Effect of N/S ratio on anoxic sulfide oxidizing bioreactors

Hydrogen sulfide (H2S) removal from biogas using anoxic bioprocesses are economic and efficient compared to physico-chemical H2S removal or other biogas upgrading technologies. Most of these biotechnologies have used nitrate-reducing, sulfide-oxidizing bacteria (NR-SOB) as the dominant microorganism for H2S removal. Anoxic sulfide removal technologies have been widely applied for both liquid and gaseous pollutants, particularly for biogas clean-up, because it is more practically applicable than the conventional aerobic systems in terms of ease of use and operational costs (Almenglo et al. 2016; Fernández et al. 2014; Soreanu et al., 2008). In this study, the performance of an attached growth bioreactor, i.e. a fluidized bed reactor (FBR) and a combined attached and suspended growth bioreactor, i.e. a moving bed bioreactor (MBBR), were tested under different operating conditions and the bioreactors were compared for their ability to perform sulfur oxidation coupled to autotrophic denitrification.In anoxic sulfide-oxidizing reactors, a crucial factor is the nitrogen/sulfur (N/S) ratio, which affects the metabolism of nitrate-reducing, sulfide-oxidizing bacteria (NR-SOB) and the ratio of the end products of sulfide oxidation such as elemental sulfur and sulfate. Thus, the objective of this study was to evaluate the effect of the N/S ratio on the thiosulfate removal efficiency in two different anoxic biofilm bioreactors, i.e. a MBBR and a FBR, as shown in Figure 1. Both the lab-scale MBBR and FBR were operated for 250 days, at room temperature (~20 ºC) and at a feed pH of 7.0 ± 0.2. The dissolved oxygen (DO) concentrations in the MBBR and FBR were 0.51 ± 0.09 and 0.26 ± 0.06 mg L-1, respectively. The FBR used in this study was previously used for thiosulfate-driven denitrification (Di Capua et al. 2017). The MBBR was inoculated by using the biomass obtained from that FBR containing Thiobacillus denitrificans as the dominant microorganism. The performance of the MBBR and FBR were evaluated under three different N/S ratios (0.5, 0.3 and 0.1). Thiosulfate was used as a substrate for sulfide-oxidizing bacteria at a constant concentration of 200 mg S-S2O32- L-1, whereas the concentration of the electron acceptor, nitrate, was decreased stepwise from 40 to 10 mg N-NO3- L-1. The performances of the MBBR and FBR can be compared in Table 1. The removal efficiency of thiosulfate was > 98% and nitrate was completely consumed during the operational time in both bioreactors at N/S ratio of 0.5. Under the nitrate-limiting conditions tested, i.e. N/S ratio of 0.3 and 0.1, the thiosulfate removal efficiencies in the MBBR (83.4 and 37.8%) were higher than those observed in the FBR (77.8 and 26.1%), resulting in a higher sulfate production.The higher DO concentrations observed in the MBBR compared to the FBR likely played a role in enhancing thiosulfate oxidation due to T. denitrificans, a dominant microorganism in the inoculum, being a facultative anaerobe which enables to use oxygen as alternative e- acceptor to oxidize the thiosulfate. Additionally, it was probably because of the different bioreactor configuration and mixing conditions.

Conclusions

The MBBR and FBR can be operated at room temperature (~20 ºC) for achieving high removal efficiencies of thiosulfate (> 98%), under autotrophic denitrification conditions, at a HRT of 5 h, feed pH of 7 and a N/S ratio of 0.5. However, the MBBR resulted in higher thiosulfate oxidation rates than the FBR after the nitrate-limiting conditions were applied. The reactor performance at a N/S ratio of 0.1 and the evaluation of the microbial community composition at different N/S ratios require further investigation.

Application oriented wear testing of wear resistant steels in mining industry

Tampere Wear Center have developed several high-stress wear testers that utilize large sized abrasive particles of natural origin and thus are able to
simulate demanding applications of the mining industry. In this work, a versatile high speed slurry-pot wear tester was developed. Research questions
studied are: 1) How to set up a wear test method for simulating the real applications?, 2) What are the wear mechanisms in high-stress wear?, and
3) What is the role of microstructure and chemical composition on wear performance of wear resistant steels?

The high speed slurry-pot tester was developed for application oriented erosion wear testing of materials used in mineral handling and processing. It
enables tests in demanding high-stress abrasive and erosive environments simulating wear, for example, in slurry pumps, tanks and pipes, dredging,
mineral crushing and grinding, screening, loader buckets, and rock drilling. The key design features of the test method are the possibility to use up to
10 millimeter sized large abrasives and sample speeds up to 20 m/s in conditions ranging from wet slurry environments to dry sand or gravel.

The work has been done in FIMECC DEMAPP and DIMECC BSA projects, the focus is in the application oriented wear testing of materials intended for
demanding wear related applications.

The effect of climate change on freeze-thaw durability of concrete structures in Finland

Lahdensivu presented in his Doctoral Thesis (Durability Properties and Actual Deterioration of Finnish Concrete Facades and Balconies, 2012) that without proper air-entrainment outdoor concrete structures have needed average of 307 freeze-thaw cycles (threshold value: t ≤ -5 °C) after a rain event in southern Finland and 388 cycles in inland for incipient freeze-thaw damage to occur. The difference between figures can be explained by the greater amount of wind-driven rain (WDR) before the freeze-thaw cycle on coastal areas.
As a consequence of climate change it has been shown that by the end of the century, the amount of WDR is going to increase 30 % at southern Finland and 40 % at inland. At the same time the amount of freeze-thaw cycles after a rain event are decreasing significantly at both locations which indicates freeze-thaw durability-wise longer service life for outdoor concrete structures. However, the latest studies show that while the amount of freeze-thaw cycles is decreasing, the amount of WDR before the cycles is also increasing significantly.
The WDR at winter time in Finland is highly orientated on west to south-east directions which can be seen also by the degradation rate observations of concrete facades and balconies based on condition assessments. In this study, the changes at WDR before the freeze-thaw events and the effect of climate change on them depending on the structure orientation are calculated to estimate the changes of climatic stress level on outdoor concrete structures.

Assessment of the Analytical Potential of HPLC-SEC for the Characterization of DOM and Nutrients in Various Types of Water

This study focused on high performance size exclusion liquid chromatography (HPLC-SEC) combined with two ultraviolet (UV, 254 nm and 224 nm) detection wavelengths to detect humic-like compounds and two fluorescence (FLU) excitation/emission (tyrosine-like and tryptophan-like) wavelengths to detect protein type compounds in water samples. Targeted particularly were further possibilities of this method, such as finding suitable chromatographic surrogates for organic matter and nutrient indicators for water types such as catchment surface waters, well waters, and onsite wastewater effluents, which have been studied little before. It was thus necessary to determine the optimum analytical conditions for exacting wastewater effluent analysis in term of eluent strength, eluent pH, and sample injection volume. Additionally, this study provided valuable information on the spatial and temporal behavior of dissolved organic matter along a catchment area and on the quality of onsite wastewater effluent and well water in sparsely populated areas.

A TSK-GEL G3000SW column, Na-acetate of 0.01 M at pH=7 eluent, and an injection volume of 30 μL guaranteed good separation of dissolved organic matter (DOM) in surface and well water samples up to 8 fractions and further up to 11 fractions in complex onsite black water effluents. For systematic analysis of high strength onsite wastewater effluents, we chose, based on calculations of global resolution at various eluent conditions, Na-acetate of 0.02 M at pH=7 eluent and an injection volume of 20 μL.

DOM concentration dropped along the catchment, as 35-75% of dissolved organic carbon (DOC) was eliminated. DOM in drains had up to 80% high molecular weight (HMW) fraction and lakes only 50-60% HMW. Drains had high DOC in summer and lakes in winter and spring with seasonal increase in DOC resulting from increased HMW fractions in these waters. The water treatment plant eliminated HMW fractions from raw water up to 100%, intermediate MW (IMW) fractions up to 87%, and low LMW fractions up to 66%. A seasonal increase in raw water DOM was detected in drinking water samples as increased IMW and appearance of HMW fractions. Of the two protein-type detections, tryptophan-type signals were clearly measured in surface water. Tryptophan-like FLU, as sum of peak height (SPH), was consistently higher in the drain affected by agriculture than in the drain in the mire area.

The study on well waters showed that, on average, shallow and deep well water differ little in quality in the sparsely populated agricultural areas studied. According to HPLC-SEC-UV254, high-DOC well water samples had clear and often dominant HMW fractions and low-DOC samples hardly any HMW fractions but dominant IMW fractions. The LMW fraction, correlating with nitrate, indicates anthropogenic influence. Nitrate was precisely calculated from the peak height (PH) of the LMW fraction detected by UV-224.

Our study on onsite blackwater effluent (BWE) and greywater effluent (GWE) disclosed the overall quality of onsite wastewater effluents with BWEs having higher mean values than GWEs for all the conventional indicators measured. The chromatograms (UV-254, tyrosine, and tryptophan) of onsite wastewater effluents showed the regular peaks for surface and well waters and extra peaks eluted over the permeation volume. Dividing the chromatograms into 3 regions helped identify the best possible surrogates for conventional indicators. Region 3 comprising the late peaks eluted over the permeation volume in the tyrosine- and tryptophanchromatograms correlated best with biochemical oxygen demand (BOD-7), showing that these fractions are biodegradable. Tyrosine-like chromatograms assess best DOC and BOD-7, trytophan-like chromatograms best total nitrogen (TN), and UV254 and tyrosine-like chromatograms best the chemical oxygen demand (COD) of wastewater effluents. Regression equations corresponding to the best correlations between the chromatographic and conventional indicators are given in the study for reliable calculation of DOC, COD, and BOD-7 and rough assessment of the TN.

This study highlights the fact that secondary interactions, unwanted in SEC can be exploited in nitrate measurement of well waters and BOD assessment of high strength wastewater effluents.

Feasibility of Flexible Biomass Utilization in Energy Systems

Globally the fastest growing renewable energy production methods are weather
dependent solar and wind power production. However, their locality and fluctuating nature may make the energy demand and production unbalanced and thus increases the need for system flexibility.
Biomass is available in one form or another almost everywhere on Earth. It has
been recognized to have potential for providing flexibility into energy systems. Even though technological possibilities for biomass utilization are numerous, detailed costs of the flexibility means are often ignored. This thesis looks in detail into the feasibility of flexible biomass utilization methods through practical examples; biomass to chemicals, biomass to heat and power and biomass as a transport fuel.
The results of this study provides suggestions how to increase the feasibility of
biomass utilization in energy system levels. The results showed that biomass can
provide flexibility through demand response, flexible production, and useful power storage. These can be achieved with currently existing technologies that can be adopted in a short timescale through introducing subsidies.. It was also shown that the feasibility of biomass utilization method can be improved through side-product, optimized running mode, or technical improvements. The most efficient way to increase the feasibility was operational optimization. The key factors in the feasibility of biomass utilization methods are investment and fuel costs. However, as sustainable amount of biomass is limited other flexibility means will be needed.
Future studies should include accurate forecasting on cost and price
development, since these are often based on assumptions. In addition, sustainability and carbon emissions of the whole biomass production chain should be studied.

Biovalorisation of liquid and gaseous effluents of oil refinery and petrochemical industry

Liquid effluents of oil refinery contain toxic selenium oxyanions and phenol, while gaseous effluents contain toxic CO/syngas. To remove the phenol and simultaneously reduce the selenite oxyanions, a fungal-bacterial co-culture of Phanerochaete chrysosporium and Delftia lacustris was developed. Two modes of co-cultures of the fungus and the bacterium were developed. The first being a freely growing bacterium and fungus (suspended growth co-culture), the second being the growth of the bacterial biomass encircling the fungal biomass
(attached growth co-culture). Both types of fungal-bacterial co-cultures were incubated with varying concentrations of phenols with a fixed selenite concentration (10 mg/L). The suspended growth co-culture could degrade up to 800 mg/L of phenol and simultaneously reduce 10 mg/L of selenite with production of nano Se(0) having a minimum diameter of 3.58
nanometer. The attached growth co-culture could completely degrade 50 mg/L of phenol and simultaneously reduce selenite to nano Se(0) having a minimum diameter of 58.5 nm.

In order to valorize the CO/syngas by bioconversion techniques an anaerobic methanogenic sludge was acclimatized to use CO as sole carbon substrate for a period of 46 days in a continuous stirred stank reactor, supplied with CO at 10 ml/min. 6.18 g/L acetic acid, 1.18 g/L butyric acid, and 0.423 g/L hexanoic acid were the highest concentrations of metabolites produced. Later, acids were metabolized at lower pH, producing alcohols at concentrations of
11.1 g/L ethanol, 1.8 g/L butanol and 1.46 g/L hexanol, confirming the successful enrichment strategy. The next experiment focused on the absence of trace element tungsten, and consecutively selenium on the previously CO acclimatized sludge under the same operating conditions. An in-situ synthesized co-polymeric gel of N-ter-butyl-acrylamide and acrylic acid was used to recover ethanol, propanol and butanol from a synthetic fermentation broth. The scope of repeated use of the gel for the alcohol recovery was investigated and every time
approximately 98% alcohol was recovered.

High rate anaerobic treatment of LCFA-containing wastewater at low temperature

Fats, oil and grease (FOG) are a significant constituent in numerous wastewaters such as those in dairy industry. The hydrolysis of FOG result in the production of long chain fatty acids (LCFA) which destabilize the anaerobic treatment process due to their physico-chemical and microbial toxicity effects. Harnessing the high methanogenic potential of FOG necessitates effective treatment of high LCFA loads, wherein the feasibility of LCFA treatment at low temperatures has been not investigated up to now. The aim of this thesis was to study the feasibility of high-rate anaerobic treatment of LCFA-rich wastewaters at low ambient temperatures using dairy wastewater.

The screening of mesophilic inocula for treatment of mixed LCFA containing synthetic dairy wastewater (SDW) in batch studies showed that granular sludge inoculum achieved faster and higher methane yields (76-82% of theoretical yield) than the two municipal digestates (1-72%) at both 20 and 10°C. The LCFA
degradation capacity in the granular sludge inoculum was attributed to the presence of β-oxidizing bacteria from the family Syntrophaceae (Syntrophus and uncultured taxa), the acetotrophic activity of Methanosaeta and the putative syntrophic acetate oxidizing bacteria (SAOB).

Continuous high-rate treatment of SDW was found to be feasible in expanded granular sludge bed (EGSB) reactors at 20°C (hydraulic retention time (HRT) 24 h, LCFA loading rate (OLR) 670 mgCOD-LCFA/L·d) with a soluble COD (sCOD) removal of 84–91% and methane yield of 44–51%. SDW feeding for longer than two months resulted in LCFA accumulation, which led to granular sludge flotation (36-57%) and disintegration (reduction in d50 of 24–33% and 75–84% in settled and washed-out granules, respectively). To counter the LCFA induced granular sludge disintegration and flotation, a novel reactor type, dynamic sludge chamber-fixed film (DSC-FF), was designed and achieved sCOD removal of 87-98% at HRTs from 12-72 h (LCFA loading rate 220-1333 mgCOD-LCFA/L·d) at 20°C. Moreover, even at the 12 h HRT, the unsaturated LCFAs
(linoleate and oleate) were treated and only part of saturated LCFAs (stearate, palmitate) remained after treatment in the DSC-FF reactors. An increased methanogenic activity was established in the reactor sludges during reactor runs, which was evidenced by a higher acetotrophic activity in the granular sludge (from DSC), and a higher hydrogenotrophic activity in the biofilm (from FF) indicating development of distinct metabolic capabilities in the different reactor compartments.

High throughput 16S rRNA sequencing showed that the relative abundance of the acetoclastic methanogen, Methanosaeta, increased in EGSB reactors and in the active microbiomes of granules (from DSC) and biofilm (from FF) when fed with increasing LCFA concentrations. This suggested acetoclastic methanogenesis as the predominant methanogenesis pathway for SDW and presumably, LCFA degradation at 20°C. Relative abundances of the taxa known to have β-oxidizing and methanogenic activity were high in the active microbiomes during SDW treatment in DSC-FF reactors at 20°C. The biofilm
microbiome (from FF) had a prominent presence of the β-oxidizing bacteria Syntrophus and of the hydrogenotrophic methanogen Methanospirillum in comparison to the presence of the acetogenic bacteria, Syntrophobacter, Desulfobulbus, and Geobacter, and of the acetoclastic methanogen in the
granular sludge microbiome, suggesting a role of these different taxa during LCFA degradation.

In summary, this work demonstrated successful inoculum selection at low temperatures (10 and 20°C), and high-rate anaerobic LCFA degradation at 20°C using novel reactor design (here, DSC-FF). The key bacterial and archaeal taxa involved in the anaerobic conversion of LCFA to methane at 20°C were also
deduced.

Digestate valorization for bioremediation of petroleum hydrocarbons contaminated soils

Petroleum contaminated soils constitute an environmental issue which may be solved with the help of bioremediation. Soil bioaugmentation with petroleum degrading microorganisms is an efficient clean-up strategy. Currently scientific interest is focused on searching new sources of microorganisms able to degrade hydrocarbons which serve as species pools for enrichments during inoculum preparation. Bioaugmentation strategy are especially important in soils with
low level of organic matter and low microbial counts (e.g. after intensive chemical treatments). No studies were performed up to date while considering the potential of organic fertilizers and amendments as a microbial seeding source for bioremediation. In this thesis, for the first time, digestate as an example of organic amendment, was studied in terms of indigenous microbial
community which can be involved in degradation of linear hydrocarbons. Digestate is an organic by-product of biogas production via anaerobic digestion processes and has a great potential as soil fertilizer due to concentrated nutrients and low content of easily biodegradable compounds (which could be used by bacteria as a preferential carbon source over hydrocarbons). However, the potential of microbial community of digestate was never studied in terms of petroleum hydrocarbons (PHCs) degradation.

In this thesis, digestate was examined as microbial seeding for bioremediation of weathered petroleum hydrocarbon contaminated soils. The goals were : I) to check the presence of alkanes degrading bacteria in digestate enrichments and compare alkanes degradation potential with enrichments from petroleum contaminated soils, ii) verify the effect of digestate application on soil microbial community and microbial activity, iii) study the presence of functional genes
responsible for alkanes degradation (alkB genes) in digestate and amended soils.

During the first experiment, 7 microbial enrichments were developed from various digestates (including composted digestate), a petroleum contaminated soil and from mix of soil with digestate. After 3 weeks of incubation the highest diesel fuel removal was observed for enrichments originating from composted digestate and from the petroleum contaminated soil (78 and 77 % diesel fuel removal, respectively). Enrichments obtained from digestate mixed with soil displayed lower performance than single source enrichments. In all enrichments,
presence of alkB genes was promoted during the incubation. The experiment revealed the presence of alkB genes in bacteria from digestate and confirmed their ability to degrade diesel fuel.

In a second experiment, 6 different treatments were performed in microcosm using two industrial petroleum contaminated soils having different textures: a clay rich soil and a sandy soil. After 30 days of incubation, the highest petroleum hydrocarbons removal was observed in microcosms containing: digestate together with bulking agent (17.8 % and 12.7 % higher than control in clay rich soil and sandy soil, respectively) or; digestate together with immobilized bacteria (13.4 % and 9 % higher than control in clay rich soil and sandy soil, respectively). Distinct microbial groups were formed in amended and non-amended soils. Genera containing species able to degrade hydrocarbons like Acinetobacter and Mycobacterium were abundant in digestate and soil amended with digestate. The study proved that digestate contains high concentration of alkB genes, significantly higher than contaminated soils. Application of digestate significantly increased the level of alkB genes in soils which remained high during the treatment.

In a third experiment, a contaminated soil was incubated with digestate and bulking agent (used to increase porosity of soil mixture and facilitate air transfer) in bioreactors with active aeration. Initial alkB concentration was 1.5 % in contaminated soil and 4.5 % in digestate. During incubation of soil with digestate, alkB percentage increased up to 11.5 % and after additional
inoculation with immobilized bacteria this value increased up to 60 % (alkB percentage for treatment with mineral nutrients reached 0.4 %). Addition of digestate positively affected soil respiration and bacterial density, which was concomitant with enhanced hydrocarbons degradation. Incubation of soil with digestate for 2 months resulted in 74 % of hydrocarbons removal, while extra addition of immobilized bacteria increased this value to 95 %. Digestate
increased soil bacterial density and diversity of hydrocarbons degrading taxa. The experiment clearly revealed the advantage of digestate over mineral fertilizer due to soil enrichment in TPH degrading taxa and thus a more efficient bioremediation.

This thesis for the first time analysed the potential of indigenous bacteria from organic nutrient source in bioremediation. The obtained results proved that digestate is a good source of bacteria caring alkB genes curtail in alkanes metabolism. Moreover, observed population of bacterial caring alkB genes was significantly greater in digestate comparing to contaminated soils. Application of digestate allowed to increase microbial activity and maintain high content of
alkB genes in the soil which enhanced PHCs degradation.

Experiments performed during the thesis are contributing for better understanding of bioremediation process with the use of organic amendment as a nutrient source. Presented advantages of digestate over mineral fertilizers were evaluated and confirmed. This thesis for the first time proposes organic amendment, like digestate to be considered not only as a nutrient source but also as a valuable source of microorganisms for soil bioaugmentation/biostimulation. Developed experimental treatments are a good starting point for further assessment of digestate during field scale treatments, however detailed risk assessment analysis including effect of potential pathogens contained in digestate on human health and studies analysing the effect of digestate leachates on groundwater quality need to be performed.

ADM1 Based Mathematical Models For Assessing The Effect Of Trace Elements Dynamics On Solid Waste Anaerobic Digestion

Anaerobic digestion (AD) is one of the most trace element (TE) rich metabolic processes in biology. Indeed, TEs are important structural components of various enzymes in the AD process. The role and fate of TEs (Fe, Ni and Co) in AD is poorly understood due to their complex biogeochemistry. The low detection limit of analytical instruments and the time consuming and challenging nature of the experimental procedures are major obstacles to the quantification of TEs in AD. In this thesis, three separate mathematical models based ADM1 have been developed to simulate the TEs dynamics and speciation pattern in an AD reactor. In particular, a TE precipitation/dissolution model, a TE complexation model and a TE adsorption model have been progressively developed to predict the effect, role and fate of TEs in an AD batch system. In all the models the extent of microbial activity in the AD process is a function of the free TE concentration in the liquid phase, which is in equilibrium with the physicochemistry of the AD reactor. The precipitation/dissolution model considers the interactions of TEs with inorganic carbon (e.g. HCO3- and CO32-), phosphorous (e.g. PO43-, HPO42-, H2PO4-) and sulfur (e.g. HS- and S2-) components. New chemical equilibrium acid-base and precipitation reactions have been implemented to study the interactions of Fe, Ni, Co with carbonate, phosphate and sulfide components. The effects of deficiency, stimulation, inhibition and toxicity of TEs on microbial activity have been modelled based on a hormesis type TE dose-response inhibition function. The microbial uptake of TE and the TE inhibition on special microbial activities have been defined as well. Release of TEs as a disintegration product has been also considered to account for the TE content of the organic substrate. Model scenarios have been simulated to analyze the dynamics of TEs, starvation of TEs and the effect of initial sulfur-phosphorus ratio. In the complexation model, the interactions of TEs with organic chelators have been predicted. TE complexation reactions with VFAs and EDTA have been incorporated in the extended ADM1 model in addition to TE precipitation/dissolution processes. New acid-base chemical equilibrium reactions have been incorporated to model the dynamics of EDTA species. Complexation process rates have been defined as well. The model is able to quantify the effect of EDTA/VFA -TE complexation on methane production. Further, effect of initial Ca and Mg concentration on TE complexation has been predicted in a separate modelling scenario. Finally, a general framework able to take into account the precipitation/dissolution and complexation reactions, as well as the interaction of TEs with various surfaces available in the AD system has been developed. The model tracks the TEs dynamics in a batch anaerobic digester and as an extension of the previous contributions, incorporates the adsorption reactions of TEs with biomass, inert and precipitate (FeS). The concepts of free and occupied binding sites, and binding site density for the various surfaces have been incorporated into the model. Simulation scenarios were able to predict the effect of various organic matter concentrations, initial TE concentrations, initial Ca-Mg concentrations, initial EDTA concentrations and change in TE binding site density for biomass, inert and precipitate on cumulative methane production and TE speciation.

Rating the impact sound insulation of concrete floors with single-number quantities based on a psychoacoustic experiment

Impact sounds are different living sounds directed at floors in dwellings. Objective single-number quantities used in rating the impact sound insulation of floors and between dwellings have been presented in standard ISO 717-2 (2013). It has long been recognised that the standardised single-number quantities do not correlate well with the subjective judgement of living impact sounds. The main objective of this thesis was to develop new single-number quantities that would correspond better with the subjective experience of living impact sounds transmitted from the neighbouring dwelling upstairs.
New single-number quantities concern five different living impact sounds. In
addition, the purpose was to develop a single-number quantity that explains the
annoyance caused by all five impact living sounds. Experimental data for the
development of the new single-number quantities was produced by measuring the impact sound insulation of concrete floors with a wide scale of floor coverings. Five spectrally different living impact sounds were also measured and recorded. These sounds were walking with socks, hard and soft shoes, super ball bouncing and chair moving. A psychoacoustic experiment with an extensive number of participants was conducted to find out the loudness and annoyance of the living impact sounds and, furthermore, the associations between the subjective judgement of the sounds and objective single-number quantities. The experimental data of the impact sound insulation measurements and the psychoacoustic experiment was utilised in mathematical optimisation of new single-number quantities. As a starting point for the formulation of the new single-number quantities, it was required for them to be able to be expressed as the sum of the present single-number quantity L’n,w or L’nT,w and a new spectrum adaptation term instead of CI or CI,50-2500. An optimised reference spectrum could be developed for each of the five sound types, each leading to a better correlation between the subjective judgement of the annoyance of the sounds and the single-number quantities than can be achieved by using any of the single-number quantities presented in the standard ISO 717-2. In addition, an optimised reference spectrum was derived which explained the annoyance of all five sound types reasonably well (coefficient of determination R2 = 0.93) and better than any of the standardised single number quantities (e.g. R2 = 0.86 for L’n,w + CI,50-2500). Another objective of the thesis was to study the measurement uncertainties of various single-number quantities for rating the impact sound insulation at a frequency range of 50 Hz and above. It was shown that the measurement uncertainty of a single-number quantity depends on the impact sound spectrum of the floor type. The results also indicate that the uncertainty depends on the extent that the single-number quantity weights the low frequencies. The measurement uncertainty at a low frequency range, however, does not become so large that it would prevent developing new reference curves that weight this frequency range more strictly than
the present, standardised reference curves starting at 100 Hz.

Biochars from solid digestates as sorbing materials for metal(loid)s removal from water

Sewage sludge digestate (SSD) and the organic fraction of municipal solid waste
digestate (OFMSWD) are currently considered as alternative feedstocks for biochar production due to the high amount of the organic solid waste remaining at the end of the treatment. The pyrolysis of solid digestate is known as an alternative to promote the recycling of organic wastes and generate added-value bio-products (e.g. biochar). Generally, the digestate biochar has a much lower sorption capacity for metal(loid)s compared to activated carbons. Therefore, chemical treatment is considered as a potential option to improve the biochar surface properties and thus inducing a better sorption ability for metal(loid)s on the biochar surface.

In this present work, the SSD and OFMSWD derived biochars were treated with 2 M KOH or 10% H2O2 followed by batch washing or batch and subsequent column washings with ultrapure water. The physicochemical properties including the pH of point of zero charge (pHPZC), the Brunauer-Emmett-Teller surface area (SBET) and cation exchange capacity (CEC) were determined for all the biochars in order to link their improved surface properties to the enhanced sorption ability for metal(loid)s. All the biochars were then used to study the influence of chemical treatment and biochar washing procedure on the sorption behavior of Pb(II), Cd(II) and As(III, V) through the batch sorption kinetics and isotherms. Moreover, the As redox state distribution (i.e. As(III) and As(V)) during the As(III) sorption onto the biochar surface and in liquid solution was determined by using solid-liquid extraction followed by liquid chromatographic analysis.

Results showed increases of the pHPZC, SBET and CEC after chemical treatment of the biochar, in accordance with the enhanced sorption ability for Pb(II), Cd(II) and As(V). For instance, the maximum sorption capacity (Qm) was increased from 1.6 µmol g−1 (As(V)) and 15.4 µmol g−1 (Cd(II)) on the raw SSD biochar to 8.1 µmol g−1 (As(V)) and 306.1 µmol g−1 (Cd(II)) after the H2O2 and KOH treatment, respectively (at initial pH 5.0). Similarly, the Qm of Pb(II) was also increased from 31.4 µmol g⁻1 (raw SSD biochar) to 121.9 µmol g⁻1 on the H2O2 modified SSD biochar. However, the sorption capacity for Pb(II) was not determined after KOH treatment due to the failing of the Langmuir isotherm model to fit the experimental data. This indicates that insufficient washing of
the KOH-modified SSD biochar can hinder the Pb(II) sorption due to the release
dissolved organic compounds from this biochar that may interact with Pb2+ and thereby forming Pb-ligand complexes in the solution. In addition, the As redox distribution showed a large oxidation (70%) of As(III) to As(V) in KOH-modified SSD biochar with batch washing, while As(III) was partially oxidized (7%) in the KOH-modified SSD biochar with batch and subsequent column washings. This highlights an important role of washing procedure for sorption of metal(loid)s, particularly for Pb(II) and As(V).

The As extraction followed by liquid chromatographic analysis was successfully
established to quantitatively recover and preserve As(III) oxidation with the use of ascorbic acid. During the sorption kinetics, As(III) may be stable or partially oxidized depending on the biochar treatment. In addition, the oxidation of As(III) was strongly induced by the biochar material and to a lesser extent by the release of dissolved compounds from the biochar.

In summary, digestate biochars with the chemical treatment followed by a proper
biochar washing procedure can be successfully used as potential sorbents to enhance the Pb(II), Cd(II) and As(III, V) sorption capacity. Moreover, the determination of As redox distribution on the biochars and in liquid phase during the sorption process can be achieved through the As extraction and chromatographic analysis, providing a better understanding of the transformation between As(III) and As(V) in the biochar-liquid sorption system.

Fate of trace elements during and after anaerobic digestion: a sequential extraction method and DGT technique to assess bio-accessible trace elements in digestate

Different chemical interactions between trace elements and organic/inorganic compounds originating from the substrate and generated during the anaerobic digestion process will determine the speciation of trace elements in anaerobic digesters. After anaerobic digestion, digestates are exposed to oxidizing conditions which may favor a change of trace elements’ speciation and consequently bio-accessibility for soil microorganisms and plants when digestates are spread on lands as organic amendment. Several techniques were used to assess the mobility, accessibility, and potential bio-availability of
trace elements in digestates for environmental risk assessments of digestate utilization as a soil fertilizer. The aim of this thesis is to evaluate a sequential extraction procedure and the diffusive gradients in thin films technique (DGT) to assess bio-accessible trace elements in digestate samples. Samples were taken from full-scale anaerobic digestion plants treating a mixture of industrial and municipal solid wastes or sewage sludge. The elements investigated include Al, As, Cd, Co, Cr, Cu, Fe, Mn, Mo, Ni, Pb, Sb, Se, Zn and W.

A sequential extraction procedure, originally conceived for organic matter fractionation, was implemented to simultaneously extract organic matter and trace elements in a substrate and digestate sample. It was observed that more than 60% of total As, Cd, Co, Fe, Mn, Ni and Zn were extracted along with the operationally defined organic matter fractions in both samples. In contrast, a lower recovery was observed for Al, Cr, Cu, Mo and Pb. These elements were mainly found in the dissolved organic matter fraction where soluble trace elements (e.g. free ions and complexed with organic/inorganic ligands) are
likely bio-accessible for microbial up-take. Moreover, a high portion of elements was found in the mineral fraction (e.g. sulfide), which was considered poorly bio-accessible. However, the feasibility of using the aforementioned method was questioned following the low efficiency of extraction of certain trace elements during the extraction procedure. Moreover, it was acknowledged that chemical reagents employed during the extraction procedure could have promoted a dissolution/precipitation of trace elements and therefore a change in their fractionation.

Therefore, DGT technique was tested to fractionate trace elements and it was observed that this technique increased the sensitivity of trace elements monitoring compared to conventional dissolved elements measurements in digested sewage sludge. However, it was observed that the DGT samplers’ deployment time in digested sewage sludge should be carefully evaluated. Additionally, the digestate matrix lowered the accumulation of some trace elements in the DGT samplers. Therefore, DGT labile trace elements (i.e. most bio-accessible species) can be correctly estimated provided a careful adapta-
tion of the deployment time as well as an evaluation of the matrix effect is performed in digestate samples. Unless this, general trend of labile trace elements over time could be estimated such as the distribution of labile trace elements over time in digestate exposed to air. Therefore, the effect of atmospheric air on the mobility and bio-accessibility of trace elements, including labile and soluble fractions, in digested sewage sludge was investigated. The exposure of digestate to air promoted dissolution of Al, As, Co, Cr, Cu, Fe, Mn, Mo and Pb, suggesting that a possible increase in their mobility may likely occur
during digestate storage in open tanks or handling before land spreading. Labile elements’ fraction increased only during an increase of aeration (except for Fe and Mn), suggesting that their short-term bio-accessibility can increase only after significant aeration as the one assumed to occur when digestate land spreading takes place.

These results open new fields of investigation for improving estimation of bio-accessible trace elements in digestate samples. For example, DGT technique should be further explored to accurately estimate labile trace elements concentrations in digestates.

Nutrient and organic matter removal from wastewaters with microalgae

Use of microalgae in wastewater treatment has been increasingly studied to integrate with or replace the present treatment systems for removal of nutrients and other pollutants. The potential advantages of this integration (wastewater treatment and microalgal cultivation) could be simultaneous recovery of nitrogen and phosphorus and the use of produced microalgal biomass as feedstock for e.g. biofuel, fertilizer and/or energy. However, the use of microalgae in wastewater treatment is mainly in research stage due to e.g. low nutrient removal and microalgal biomass growth. The aim of this thesis was to enable efficient nutrient and organic matter removal from wastewaters by microalgae while promoting microalgal biomass production. Chlorella vulgaris and Scenedesmus acuminatus were successfully grown in batch photobioreactors with liquid digestates from anaerobic digestion (AD) of biosludge from a municipal wastewater treatment plant (ADMW) and a pulp and paper mill wastewater treatment plant (ADPP). The final ammonium removal efficiencies were above 97% when cultivating both microalgae separately in ADPP, however, only 24% and 44% of ammonium were removed from ADMW by C. vulgaris and S. acuminatus, respectively. Both microalgae efficiently removed phosphate (>96%), while color (74–80%) and soluble COD (27–39%) were partially removed from ADMW and ADPP. The obtained highest S. acuminatus biomass concentration (7.8–10.8 g L-1 VSS) in ADPP is among the highest yields reported for microalgae in real wastewaters. Higher S. acuminatus biomass yields were obtained in thermophilic ADPP (without and with pretreatment prior to AD: 10.2±2.2 and 10.8±1.2 g L-1, respectively) than in pretreated mesophilic ADPP (7.8±0.3 g L-1). In addition, the highest microalgal biomass concentration and methane yields were obtained in the same integrated AD and microalgal culti- vation system (thermophilic AD with pretreatment). The iron (0.1, 1.0, and 1.9 mg L-1) and sulfate-sulfur (3.7, 20, and 35.8 mg L-1) concentrations were found to affect nitrogen removal efficiency and microalgal biomass concentration more in the media with nitrate than with ammonium, probably due to different microalgal assimilation mechanisms for nitrate and ammonium. In this study, synthetic medium with nitrate as nitrogen source with 1.0 mg L-1 iron and 35.8 mg L-1 sulfate-sulfur enabled the highest microalgal biomass concentration. The effect of iron concentration on nitrate removal efficiency and microalgal growth was more significant than that of sulfate concentration, while the interaction effect between sulfate and iron was not observed. The average ammonium removal efficiency (14 to 30%) and microalgal biomass concentration (0.50 to 1.17 g particulate organic carbon per L) in continuous-flow membrane photobioreactor were promoted by adding a low concentration of zeolite (0.5 g L-1). The zeolite likely provided a habitat for attached growth of microalgae and high availability of ammonium for growth on the surface of the zeolite due to ammonium adsorption to zeolite. Further increase in zeolite concentration (from 0.5 to 1 and 5 g L-1) did not improve ammonium removal efficiency or biomass concentration. This was likely due to the increased solution turbidity caused by breaking apart of added zeolite particles into finer particles, which reduced light availability. In summary, this work showed the possibility of utilizing microalgae in wastewater treatment to efficiently remove nutrients and organic matter, and simultaneously promote microalgal growth. Selecting suitable microalgal species for the specific wastewater to remove nutrients and organic matter is essential to promote algae-based wastewater treatment applications.

Hydrogen sulfide removal from synthetic biogas using anoxic biofilm reactors

The aim of this work was to develop and study anoxic bioreactors for the removal of reduced inorganic sulfur compounds from liquid and gaseous waste streams. In addition, the aim was to enable process integration for the simultaneous treatment of H2S contaminated gas streams and NO3--containing wastewater. The experiments related to sulfide oxidation in the liquid phase were conducted in two different attached growth bioreactors, i.e. a fluidized-bed reactor (FBR) and a moving bed biofilm reactor (MBBR), inoculated with the same mixed culture of sulfur-oxidizing nitrate-reducing (SO-NR) bacteria. The bioreactors were operated under different nitrogen-to-sulfur (N/S) molar ratios using S2O32- and NO3- as an energy source and electron acceptor, respectively. Results revealed that both the FBR and MBBR achieved S2O32- removal efficiencies (RE) >98% and completely removed NO3- at an N/S ratio of 0.5. Under severe nitrate limitation (N/S ratio of 0.1), the S2O32- RE in the MBBR (37.8%) was higher than that observed in the FBR (26.1%). In addition, the MBBR showed better resilience to nitrate limitation than the FBR as the S2O32- RE was recovered to 94% within 1 day after restoring the feed N/S ratio to 0.5, while it took 3 days to obtain 80% S2O32- RE in the FBR. Artificial neural network models were successfully used to predict the FBR and MBBR performance, i.e. S2O32- and NO3- RE as well as sulfate production. The SO-NR biomass from the MBBR was used to inoculate an anoxic biotrickling filter (BTF), which was studied for simultaneous treatment of H2S and NO3- containing waste streams. In the anoxic BTF, a maximum H2S elimination capacity (EC) of 19.2 g S m-3 h-1 (99% RE) was obtained at an inlet H2S load of 20.0 g S m-3 h-1 (~500 ppmv) and an N/S ratio of ~1.7. As some NO3--containing wastewaters can also contain organic compounds, the anoxic BTF inoculated with Paracoccus versutus strain MAL 1HM19 was studied for the simultaneous treatment of H2S, NO3- and organic carbon containing waste streams. With this BTF, NO3- and acetate removal rates of 16.7 g NO3--N m-3 h-1 and 42.0 g acetate m-3 h-1, respectively, were achieved, which was higher than the values observed in the BTF inoculated with the mixed culture of autotrophic SO-NR bacteria (11.1 g NO3--N m-3 h-1 and 10.2 g acetate m-3 h-1). Anoxic BTFs were operated under several transient conditions (i.e. varied gas and trickling liquid flow rates, intermittent NO3- supply and H2S shock loads) to evaluate the impacts of sudden changes that usually occur in practical applications. The different transient conditions significantly affected the H2S EC of the anoxic BTF. After applying H2S shock loads, the H2S RE fully recovered to >99% within 1.7 days after resuming normal operation. In summary, the MBBR was more effective for the removal of S2O32- than the FBR, especially under nitrate limited conditions. Based on the short recovery times after exposure to transient-state conditions, the anoxic MBBR and BTF were found to be resilient and robust systems for removal of reduced sulfur compounds under autotrophic and mixotrophic conditions.

Characterization and biological stabilization of fine fraction from landfill mining

Landfilling has been the major method to dispose waste for the decades, thus there are thousands of landfills around the world. Landfills contain large amount of resources, which could be used as material or energy. There is an increasing interest for landfill mining which means excavation and processing of waste materials mined from landfills. While previous landfill composition studies have focused especially on metal recovery and combustible materials, they have shown that landfills contain significant amounts of soil type material with small particle size, referred as fine fraction (FF). As redisposal of FF after landfill mining is expensive and causes emissions for decades, FF should be treated to increase value for reuse. The aim of this thesis was to assess in details the characteristics of the FF and to evaluate the effects of different biological treatment methods on stability and characteristics of FF. In this study, FF was sampled from two landfills representing different eras of material consumption and waste management practices: Kuopio, landfilled 2001–2011, and Lohja, landfilled 1967–1989.

The Kuopio landfill was found to contain 38–54 % of FF (< 20 mm) and the Lohja landfill 40–74%. FF contains in various amounts of organic matter (VS 6–27% of TS), nutrients (1.4–8 kg N/t TS, 1–1.5 kg P/t TS) and soluble organic compounds (e.g. 0.5–4.6 kg COD/t TS). The organic matter content, biomethane potential (0.4–27 L CH4/kg TS) and respiration activity (1.4–2.4 g O2/kg TS) were detected to be higher in top layer of new landfill (1–5 years old) while bottom layer of new landfill (6–10 years old) was similar to old landfill (24–46 years old). Biological activity may limit the utilization of FF after landfill mining, thus FF needs to be stabilized to reduce biological activity. Furthermore, FF may also contain hazardous compounds, which needs to be assessed when evaluating the use of FF.

To reduce biological activity of FF, the anaerobic and aerobic stabilization of FF were studied in two laboratory experiments employing simultaneous four leach bed reactors operated for 173–180 days. In anaerobic stabilization, methane production was found to range from 9 to 18 m3 CH4/t VS for FFs from both landfills. Irrigation of FF was necessary for efficient methane production while sludge addition providing both moisture and inoculum deteriorated the characteristics of FF.

Aerobic stabilization reduced more efficiently organic matter content and biological activity from FF compared with anaerobic treatment. Ammonium nitrogen in the leachate was removed rapidly in aerobic treatment due to nitrification. Organic matter and soluble compounds were efficiently removed with continuous water adding, regardless of anaerobic and aerobic conditions, while leachate recirculation introduced those back to the reactor. The scaling up of the anaerobic and aerobic stabilization methods of FF showed that applied technology, for example aeration or irrigation method, and size of treatment area have major effects on the costs of FF treatment. However, anaerobic stabilization and aerobic stabilization with passive aeration without continuous irrigation would have similar costs in similar sites.

In conclusion, FF may need stabilization due to organic matter content and biological activity before utilization. Both anaerobic and aerobic stabilization improved the quality of FF by reducing organic matter content and biological activity. Both treatment methods can be used in full scale stabilization of FF. The treatment of FF has potential to increase the value and usability of FF. Treatment concept and technology should be further optimized in pilot and full scales.

Rural Water and Sanitation: Community Managed Project Approach for Sustainability in Ethiopia

Water is a natural need and basic requirement of humankind. Civilization, human settlements, establishments of industry, and locations of agricultural farms have been linked to the presence of water sources. However, the availability of freshwater resources is gradually becoming more challenged by climate change, and service production is being influenced by several factors, including population growth and service breakdowns. A potable water supply for all is unquestionable for enhancing development, education, economies, and social performance. Moreover, sanitation is mandatory for maintaining clean and potable water supply sources. Striving to improve water and sanitation services and focusing on service delivery are fundamental to societies’ overall wellbeing.

The concept of service delivery extends beyond investment in the initial implementations of systems. Instead, it includes sound operation and maintenance of facilities and ensures availability of services throughout the lives of the built systems. Service delivery endeavours are overwhelmed by the implementations of new systems because most of the actors in the sector are actively building new schemes instead of rehabilitating existing ones. Therefore, the tendency in service coverage often means moving two steps forward and one step back because of service failures. To overcome this challenge, the future paradigm should be to intensify the service delivery and make it as important as the implementation of new systems. Stakeholders, particularly user communities, should be involved in every step of the process of implementing the systems that serve them to establish feelings of ownership and to give them active roles during post-construction.

The objective of this study is to obtain insight into service delivery in which the user community is at the centre of service production. It assesses the effects and effectiveness of the Community Managed Project Approach (CMP) in Ethiopia. The study was conducted in the Amhara and Benishangul-Gumuz regions in northwest Ethiopia. These regions were selected because of the presence of CMP and the availability of other implementation approaches for comparison. Data were collected using numerous methods, such as household surveys (n = 1806), focus groups (n = 49), field observations (n = 49), and personal interviews with governmental officials at the district, regional, and federal levels (n = 7). Based on these data, four peer-reviewed journal articles and one international peer-reviewed conference paper were published.

The results of this study indicate that community management is a preferable way to extend water supply and sanitation services in rural areas. The participation of user communities should be managed so that genuine participation leads to feelings of ownership. However, all types of participation (labour, financial, and material contributions) are not always possible to achieve ownership. In some circumstances, the concept of participation might be abused, which might lead to forced involvement. In that case, the dream of community participation might not be realized. Regarding this, CMP has remarkably performed for reaching and involving user communities. To create strong, cohesive, and collective actions, exploring local experiences is crucial. For example, the traditional water management of the Borana and Konso communities in southern Ethiopia are significantly more sustainable than the modern systems built in these areas because of the philosophical differences in management between the community schemes and the introduced schemes.

This study suggests that a wide variety of perspectives on service provision and production should be considered. Community participation should be clearly defined and sensibly implemented. Failure of community participation in the process of building community management might be due to technical experts’ lack of understanding of the reasons that a community should be involved and to citizens’ resistance. Several factors are identified as reasons for frequent service failures in rural water supply, including institutional and social aspects. Therefore, understanding the factors behind the problems, incorporating social capital, and engaging traditional knowledge could improve efforts to sustain service delivery.

Negotiating Groundwater Governance: Lessons from Contentious Aquifer Recharge Projects

Groundwater is an invaluable part of our natural, built, and socio-economic environments. In global context, groundwater is the largest freshwater resource: almost half of all drinking water is abstracted from underground. During the last few decades, Finnish community water supply has increasingly relied on natural and artificially recharged groundwater as raw water source. Currently, their combined share of the water supplied is some 66 percent, out of which 16 percent is artificially recharged. However, potential groundwater areas and places for groundwater recharge are sparsely situated. Thus, large city centres, with their increasing need for fresh water supply, are obliged to withdraw groundwater from afar, often crossing municipal borders. This may cause tensions between different jurisdictional units; generally, between rural and urban areas. This research illustrates how cooperation between municipalities can turn into a conflict. Indeed, there are several examples of local conflicts around the inter-municipal groundwater projects in Finland. Many projects which are justified on both technical and economic grounds have problems in gaining legitimacy among local inhabitants. Oppositions emerge and projects may go through long litigation processes.

A contentious groundwater project can be classified as a complex management problem: it is unpredictable, uncontrollable, and it has several, often contradictory interpretations. Therefore, conventional groundwater management approaches, drawing from expert-based instrumental rationality, often are insufficient for successful project planning and implementation. Indeed, the emerging paradigm emphasizes collaborative approaches to complex management problems in the fields of natural resources management as well as urban planning. Water services (water supply, wastewater treatment, and storm water management) are inherently bound to these fields through their multiple connections with aquatic environment, required technical infrastructures, and influence on socio-economic development.

The main objective of this study was to find new perspectives for groundwater governance by analysing contentious cases that operate in field of water services, thus connecting the contexts of natural resources management and urban planning. Accordingly, the research problem was formulated as follows: Which are the major constraints in large scale groundwater projects from the perspective of collaborative governance, and what lessons can be drawn for future collaboration?

The research problem was addressed through negotiation theory and discursive framework which adhere to social constructionist tradition. Through these theoretical and methodological considerations, this study enclosed conflict analysis and discourse analysis. These methods were exploited in a comprehensive analysis of the two case studies where inter-municipal water supply projects, based on the managed aquifer recharge (MAR) technology, were contested by local inhabitants. First case is situated to southwestern coastal area of Turku Region. It started already in the 1970s as a long-distance water transfer project, and was finalized in 2010 when an MAR plant started to operate on the esker of Virttaankangas. However, the other case, situated to Tampere Region, started in 1993, and the process is still unfinished.

The results of this study indicate that the water management sector is strongly grounded on instrumental rationality when solely expert knowledge is considered as a legitimate source of information. Accordingly, planning and management of the MAR projects concentrated mainly on the visible tip of an iceberg, instead of managing the whole. The interaction between parties was based on competitive mindset and zero-sum game; thus, the underlying interests and the complexity of the project were not recognized. Strong positions were taken, which precluded the possibility of finding mutual gains.

Although cases involved some collaborative efforts, they were used only as casual tools without really relying on collaborative rationality. However, in groundwater governance it should be other way round: the core should be in collaborative rationality while some of the tools can be obtained from rationalistic expert-based planning. Thus, legitimacy for the project should be gained through joint knowledge production as well as interaction, where addressing stakeholders’ interests instead of predefined goals could help in finding mutual gains and creative new options for collaboration. Furthermore, in this process, water managers and experts should be more like facilitators than holders of the only legitimate source of knowledge and the stakeholders like partners rather than informants or adversaries.

Paradigman jäljillä: Tutkimus vesihuollon ajattelumalleista

The municipalities of Finland are facing interesting times; the public sector as a whole is struggling with economic and productivity challenges and is striving to find innovative development strategies for the future. The prevailing conditions are reflected in the built environment, in the technical sector of municipalities and, therefore, in infrastructure services such as water services. Generally speaking, water services are perceived to be static in nature that have operated successfully in the relatively unchanging conditions of history. However, the increasing complexity and faster rate of change in the operating environment are forcing water services to be more innovative and able to explore their own role as a part of variety of systems as well as to formulate problems accordingly. The way water services are thought and seen ultimately defines what kind of solutions are produced and services delivered. Thinking patterns related to water services shape its future.

These thinking patterns – the paradigms of water services – are in the spotlight in this doctoral dissertation. For this purpose, the conceptual framework of two alternative paradigms of water services is constructed. Paradigm 1 represents a production-oriented world view that rests on reductionist thinking, production-based value creation logic, and closed-context expertise. Paradigm 2 embodies a service-oriented world view that is based on holistic systems thinking, service-based value creation logic, and open-context expertise. Based on this conceptual framework, the four selected research articles are explored, following the principles of qualitative research. The purpose is to find and clarify the paradigm related clues of the articles, and hence approach the question: how are water services thought?

The theme of the first article relates to the relationships between water utilities and external service providers. It shows that the relationships are based on mistrust that must be managed by continuously tightening contracts. As a consequence of the dominant paradigm, there is no foothold left for building trust between parties. The second article highlights the identity of water services by asking what kind of meanings water utilities place on water services. Reflecting the findings in relation to the paradigms, it is seen that the aim of water services is perceived to be the realization of top-down imposed goals. This explains why sense-making with wider systemic meanings hardly occurs. The theme of the third article relates to the idea of inverse infrastructure, which refers to user[IV] driven developed infrastructures that have the characteristics of self-organization and volunteerism. These kinds of alternative infrastructure solutions shift the power of decision away from formal systems, hence this tendency is not necessarily favoured in the municipal infrastructure policy. In the light of paradigm exploration, municipal infrastructure policy should be enabling and integrative. The theme of the fourth article, in turn, deals with social norms. It is argued that following social norms over sectoral boundaries has an effect on trust and acceptance towards the water services.

Regarding all four articles, this study revealed that, along with material and quantitative dimensions, there resides invisible system dimensions affecting the service that is ultimately provided. If water services are perceived by a production-oriented paradigm, these less obvious system dimensions are ignored or formulated in an inappropriate manner. A service-oriented paradigm is, in turn, more responsive to different system dimensions; it also emphasizes that the less obvious phenomena can have an influence on the service as a whole. From the research that has been carried out, it can be concluded that if the purpose of water services is to create well-being for the wider society, then there seems to be a need for a paradigm shift that puts more consideration on the changing and ever more complex operating environment. In that case, the ways water services are thought and understood have to change towards a world view outlined by the serviceoriented paradigm. It helps to rediscover the linkage between the water services and societal development.

Access to Water? Dynamic Capacity Change for Sustainable Rural Water and Sanitation Services for All

The lack of adequate safe drinking-water together with poor sanitation and hygiene imposes an extremely high disease burden on millions of children and adults. This compromises well-being and productivity, and aggravates the cycle of poverty. Cultivating capacity for change is an important element of practically every policy reform, development programme, and country strategy aiming to improve well-being of its citizens, and with it also, e.g., water services and sanitation. The purpose of this dissertation was to recommend ways for rural water and sanitation sector specific programmes and projects to inspire capacity change for continued learning, adaptation, and innovation in the face of ever-new challenges in a volatile and unpredictable local and global environment, while the system in itself was assumed to be complex and wicked already at the present time.

The specific objective was to develop futures-oriented frame of reference that can be applied for policy, programme, and project purposes. It draws from a wide range of action research the author has been involved with in Nepal, Guyana, Tanzania, and Bangladesh. It consists of six international peer-reviewed scientific articles and three case studies. The approach is constructivist and actororiented, it pays attention to agency and institutions, is plural rather than singular, differentiating rather than generalizing. The frame of reference is based on three analytical levels: 1) individual, 2) organizational/institutional, and 3) enabling environment.

Rural water sector must pay attention to rural livelihoods and cross-sectoral issues to truly benefit rural development and well-being. This can be done through the multiple-use water services paradigm, adding ecological sanitation. Two of the articles studied a bi-lateral water project in Nepal that combined water supply, sanitation, irrigation, and hydro-energy with livelihoods, small cottage industries and micro-finance (cooperatives) within one project operating through local government.Conceptually and policy-wise complex system translated into tangible benefits and positive impacts in the poorest and remotest corners of Nepal once the enabling environment was conducive to allow this. It proved out to be a useful instrument for making change happen, empowering communities and encouraging continuous learning, innovation, and adaptation. Empowerment is here defined as group’s or individuals’ capacity to make effective choices and then transform these choices into desired actions and outcomes and with these, into services and benefits.

Capacity related interventions need to have a vision that goes further than just the present state of affairs. Appreciating the complexity and dynamic nature of the rural water sector, the system should not be split into individual components or activities, such as individual training courses or narrow mandates that do not consider the broader framework within which they must operate and change.
The ‘capacity cube’ in this dissertation represents the ‘present’ that moves across its different dimensions simultaneously and is in constant change in time. Framing the ’cube’ allows the project or programme planners to establish the external layers of reference to give shape for the time dimension, the expected results (‘services’), the external and internal drivers and barriers to change in terms of enabling environment, and the institutions and humans therein. Among others, it recommended to further study scale application of multiple use water services with ecological sanitation in the livelihoods context and the rural water service delivery paradigm.

Production of Oleaginous Microbial Biomass by Reusing Wastewaters

Global energy demand continues to increase, which raises the question regarding how to solve the energy crisis caused by diminishing fossil fuels. There is no single alternative energy source that could substitute the fossil fuels, but microbial single cell oils (SCO) could be part of the solution. SCOs can be produced by cultivating microorganisms in wastewater in which nutrients and carbon from the wastewater are used for biomass production. In optimized conditions, microorganisms begin to accumulate lipids, and these lipids can be further refined for the production of biodiesel or renewable diesel. The lipid accumulation of the microorganisms may be enhanced by culturing the microorganisms under stressful conditions. The most commonly used strategy for enhancing lipid accumulation is nitrogen starvation, but it is even more effective when combined with another stress factor, such as moderately increased salinity. In microbial lipid production, the major cost factor is often the substrate needed for the microorganisms. Therefore, utilizing inexpensive substrates and waste materials for the cultivation of oleaginous microorganisms is very desirable. Various wastewaters from municipalities, agriculture, and industrial sources have been studied, and many of these wastewaters have shown the potential for lipid-rich biomass production. Unfortunately, most of the studies have been conducted using sterilized wastewater. In large-scale applications, the sterilization of the wastewater is not cost-effective; therefore, lipid-accumulating microorganisms able to compete with the indigenous microorganisms of the wastewater need to be further studied. The aim of this work was to sustainably produce oleaginous biomass by reusing the carbon and nutrients from wastewaters. This work included an evaluation of the suitability of various wastewaters for lipid-lipid rich biomass production (Paper I), the isolation of yeasts and fungi, which could possibly accumulate lipids by utilizing wastewater as substrate (Paper II), and the determination of the ability of the isolated microorganisms to accumulate lipids by comparing them with known lipid accumulating yeasts (Paper II). Unlike yeasts and fungi, microalgae are able to use an inorganic carbon source for their growth. This feature enables the combination of wastewater and flue gas treatment. Therefore, the growth and lipid accumulation of three microalgal species were compared (Paper III), and the suitability of the most potential microalgal species for accumulating lipids in sterilized and non-sterilized wastewater was studied (Paper III & IV). Based on the results of this study, palm oil mill effluent (POME) has more potential for lipid production than chemithermomechanical pulp mill effluent (CTMP) or municipal wastewate r (MWW) (Paper I). The residual lipids and solids of POME obstructed the analyses of the microbial SCOs. Eukaryotes isolated from POME with agar plates were genetically identified as Candida silvae NRRL Y-6725 (with 100% similarity), Galactomyces geotrichum LMA-20 (with 99.8% similarity), Lecythophora hoffmannii CBS245.38T (with 96.7% similarity), and Graphium penicillioides JCM9300 (with 99.3% similarity) (Paper II). The fungus Graphium penicillioides had a great potential for lipid accumulation based on the comparison study with well-known oleaginous yeast strains (Yarrowia lipolytica DSMZ8212, Cryptococcus curvatus DSMZ70022, & Cryptococcus albidus DSMZ701097) in a synthetic medium (Paper II). The lipid content per dry weight was higher with G. penicillioides compared to C. curvatus after 15 days of incubation (29.1±3.0 wt% vs 20.2±2.9 wt%, Paper II). Unfortunately, the overall lipid concentration was lower due to a lower biomass concentration. G. penicillioides contained more than 20% lipids, so it can be called oleaginous. From the three microalgae isolated from a Taiwanese freshwater area (Chlorella sorokiniana CY1, Chlorella vulgaris CY5, & Chlamydomonas sp. JSC-04), C. vulgaris accumulated more lipids when various media, nitrogen sources, and nitrogen concentrations were studied (Paper III). The C. vulgaris in the BG-11 medium, initially containing 0.38 g NaNO3/L, produced 3.8 g/L biomass and 57.5 wt% lipids after 12 days of incubation. The most suitable wastewater dilution for the lipid accumulation of C. vulgaris on sterilized anaerobically treated piggery wastewater was 5x dilution, which resulted in initial chemical oxygen demand and total Kjeldahl nitrogen of 75.4 mg/L and 57.4 mg/L, respectively. C. vulgaris was suitable for accumulating lipids on both sterilized and non-sterilized anaerobically treated piggery wastewater (PW) (Paper IV). The highest lipid content and productivity with the non-sterilized wastewater were rather promising (32.5±3.2 wt%, 71.2±2.2 g/L/d). However, under the conditions of these experiments, C. vulgaris excreted dissolved organic carbon (Paper III & IV), and the aim in wastewater treatment is the removal of organic carbon. In summary, this work demonstrates the potential of indigenous eukaryotic microorganisms for lipid-rich biomass production. G. penicillioides isolated from POME has the potential for lipid-rich biomass production in a synthetic medium, which has not been previously reported. Similarly, C. vulgaris has the potential for lipid-rich biomass production in non-sterilized piggery wastewater, while most of the studies in the literature on C. vulgaris and wastewater have been conducted using sterilized wastewater. To enable simultaneous accumulation of lipids and efficient treatment of wastewater, special attention should be focused on the growth conditions.

Heap Bioleaching of Low-grade Multimetal Sulphidic Ore in Boreal Conditions

The bioleaching of metal sulphide ore has developed into an important industrial process to recover valuable base metals from low-grade ores, because high grade ore resources are depleting. The Talvivaara deposits in Finland have been known for decades, but have not been utilized until now, because of the low nickel concentration. The aim of this work was to study the bioleaching process of a Finnish complex multimetal black schist ore in boreal conditions. The effects of pH and leaching temperature on the dissolution of valuable metals and gangue minerals were studied. The effect of low temperature on iron oxidation and mineral bioleaching was investigated. Microbial community development at different pH values and temperatures was tested in laboratory-scale bioleaching columns and finally the community dynamics were studied in a demonstration-scale bioheap over a period of three years in Talvivaara Finland.

The experiments were carried out using laboratory-scale columns containing about 9 kg of agglomerated ore. The columns were loaded with the ore, irrigated with pregnant leaching solution (PLS) by recycling and aerated from the bottom. The tested pH range was from 1.5 to 3.0 at 21 ºC and temperature range was from 7 to 50 ºC at pH 2.5. The particle size (d80) of the ore was 7.6 mm. Surface water taken from lake near the Sotkamo deposit (slightly affected by acid mine drainage) supplemented with nutrients was used for irrigation. Aeration was provided through a diffuser inserted at the base of the column. The iron- and sulphur-oxidizing bacterial culture used in inoculation of the columns, was enriched from surface water samples (pH 4.5-6.9) obtained from the ore deposit. The pH of irrigation solution was maintained with continuous titration with H2SO4. The ore was acid consuming in all tested conditions. The actual pH of the irrigation solutions after 140 days were 0.1-0.5 units over the target values in all columns. Leaching at low pH resulted in increased acid consumption of 160 and 38 H2SO4 g kg-1 ore at pH 1.5 and 2.0 after 140 days. Temperature, at pH 2.5, had also effect on acid consumption. At 50 ºC acid consumption was highest and lowest at 21 ºC, being 29 and 8 H2SO4 g kg-1 ore, respectively.

The pH of the irrigation solution clearly affected to the dissolution of nickel and zinc. Nickel solubilization rate was 3.3 times higher at pH 1.5 than at pH 3.0, being 0.42 and 0.13 % (Ni) d-1, respectively. At pH 1.5 valuable metals yields were 59 % for Ni, 52 % for Zn, 13 % for Cu and 16 % for Co, whereas at pH 3.0 yields were 15 % for Ni, 10 % for Zn, 0.5 % for Cu and 6 % for Co after 140 days of bioleaching. No significant bioleaching happened after that at pH 1.5, 2.5 or 3.0. At pH 2.0 the maximum yields were achieved after 230 days of bioleaching. Nickel and zinc leaching rates and yields decreased nearly linearly as pH increased. Copper did not bioleach at high pH (2.5-3.0). After the beginning, no further cobolt dissolution happened at pH 3.0. Decrease in leaching rates may be due to a lack of dissolved ferric iron, serving as a leaching agent, or metal dissolution barriers created by precipitates on the ore surfaces. The ferric iron concentration in PLS increased all the time at pH 1.5, being 36 g l-1 after 140 days. At pH 2.0 the ferric iron concentrations varied, being highest 3.8 g l-1 after 97 days. At 2.5 and 3.0 no ferric iron was present in PLS and iron concentration remained low, being 15 mg l-1.

After 60 days of bioleaching the leach liquor at pH 1.5 became jelly-like due to solubilization of Si from the ore, which contained 42 % (w w-1) of SiO2. Quartz, phlogopite, and feldspars (anorthite and microcline) were the main Si-containing phases. After 110 days the Si concentration reached 2.96 g L-1 at pH 1.5. Soluble Si increases the solution viscosity and thus hinders leach liquor percolation trough the heap, lowers the oxygen transfer rate, and complicates subsequent metal extraction. Although, dissolved Si did not affect the solubilization of valuable metals, the pH value of the PLS must be kept at over 1.5 to slow down Si-containing mineral dissolution. At pH 2.5 less than 200 mg L-1 Si was solubilized and different temperatures had no effect on Si dissolution at that pH.

Based on an optimisation between the maximum valuable metal yields, leaching rates, the acid consumption, and the low dissolution of cations (Si, Al, Ca, Mg and Mn), the leaching solution pH of 2.0 was recommended for a bioheap application. At pH 2.0, the maximum leaching yields were achieved after 230 days, being 54 % for Ni, 37 % for Zn, 13 % for Cu and 12 % for Co.

Temperature strongly affected the valuable metal yields at pH 2.5. Leaching at low temperature (7 ºC) resulted in yields of 24 % for Ni, 17 % for Zn, 2 % for Cu and 6 % for Co after 496 days. The Cu leaching increased all the time during the experiment at 7 ºC, while at other temperatures it slowed down after 100 days. The highest yields were obtained at 21 ºC (26 % for Ni, 18 % for Zn, 0.5 % for Cu and 6 % for Co) after 153 days. After re-inoculation (day 65) with a thermophilic Sulfolobus culture, leaching at 50 ºC accelerated but slowed down soon and resulted in 18 % for Ni, 11 for Zn, 0.3% for Cu and 2% for Co (after 140 days). In the column leaching study, after the maximum yields, longer leaching time did not result more metals in solutions.

The redox increased during the first two months at 7 ºC and reflected the start of ferrous iron oxidation and microbial activity. The concentration of ferric iron was around 400 mg L-1 after two months. After that ferric iron was present all the time at 7 ºC and this demonstrated that more ferric iron was available for the oxidation of the mineral sulphide than at other temperatures. The leach liquor redox potential stabilized to 500-600 mV (Ag0/AgCl reference) at 7 ºC after 40 days and at 21 ºC right after beginning, whereas at 35 ºC and at 50 ºC it varied between 300-500 mV. At 50 ºC, all dissolved iron was in ferrous form inspite the variation of redox. After 50 days Fe2+ and Fetot were both 350 mg L-1 indicating that iron oxidation and precipitation occurred at the same time. Brown precipitates accumulated to the surfaces of the agglomerated ore in columns from 7 ºC to 50 ºC. Additionally, bright yellow precipitates were formed indicating elemental sulphur or Na-jarosite accumulation at 7 ºC and 21 ºC.

After 50 days of bioleaching, at 7 ºC leach liquor total cell counts (108-109 cells mL-1) were significantly higher than at other temperatures (106-107 cells mL-1). Cell counts remained that high troughout the column study. At the end of the experiment, total cell counts in the leach residues were studied. At 7, 21, 35 and 50 ºC cell counts of the leach residues were 3.4· 108, 2.3· 108, 1.1· 107 and 8.7· 106 cells ore g-1, respectively. The pH did not affect at 21 ºC the numbers of microorganisms in the PLS and cell counts remained at 106-108 cell mL-1 throughout the study and the leach residues contained about 108 cells g ore-1.

The microbial community composition and dynamics was by investigated by DNA extraction PCR-DGGE-sequencing approach. The microbial community were not affected by pH. In contrast, temperature affected the microbial populations. After the first months, Acidithiobacillus ferrooxidans AP 310 (96-99% sequence similarity, accession DQ35518) was the only species detected at 7 ºC and was also present at other temperatures. After the data of this study was published (2007), two new Acidithiobacillus species were described, A. ferrivorans and A. ferridurans. Genetically these species are very near each other. The 16S rRNA gene sequences of the bands that corresponded 99% of A. ferrooxidans AP310 (DQ35518) were identified again in 2015 using the basic local alignment search tool (BLAST). The 16S rRNA gene sequences of A. ferrooxidans at temperatures of 7 and 21 ºC corresponded 99% as A. ferrivorans SS3 (CP002985). One of the 16S rRNA gene sequences of A. ferroxidans strains at 35 ºC corresponded 99% as A. ferridurans ATCC 3302 (NR_117036). At 50 ºC, no proper A. ferroxidans 16S rRNA gene sequences were gained with the used methods. The presence of A. ferroxidans at 50 ºC was concluded based on the fact that the DGGE band was in the same place as the other A. ferrooxidans bands. The 16S rRNA gene sequences of Acidithiobacillus ferrooxidans strains in pH between 1.5 and 3.0, at 21 ºC, corresponded also 99% as A. ferrivorans SS3 (CP002985). In the light of increased knowledge, these species cannot be separated with the denaturing gradient from 40 to 70% that were used in the DGGE. A. ferrooxidans, A. ferrivorans and A. ferridurans are able to oxidize both iron and sulphur compounds.

Leptospirillum ferrooxidans DSM 2705 (98-100%, X86776) and Sulfobacillus thermotolerans KR-1 (99%, DQ124681) were mainly detected at 21 ºC and 35 ºC. Sb. thermotolerans was present at 50 ºC. L. ferriphilum D1 (99 %, DQ665909) appeared after 300 days of bioleaching and was present in every leach residue, except at 7 ºC and pH 3.0. L. ferrooxidans and L. ferriphilum are able to oxidize only iron. Sb. thermotolerans is able to oxidize both iron and sulphur compounds.

Archaeal species were analyzed two times from leach liquors and three species were detected. A species related to an uncultured archaeon clone ant b7 (99%, DQ303249), nearest known species Thermoplasma acidiphilum DSM1728 (91%, AL445067) was present in all of the leach liquors except at pH 1.5. Archaea related to Sulfolobus metallicus DSM 6482 (98%, SM16SRRN1) were present at pH values 2.5 and 3.0 and in all other temperatures, except at 7 ºC. Sulfolobus metallicus is able to oxidize both iron and sulphur compounds. Ferroplasma acidiphilum DR1 (98%, AY222042) that can oxidize only iron, was present at pH 2.5 and 2.0, and in all temperatures, expect at 35 ºC.

The mixed iron- and sulphur-oxidizing culture in the recirculation solution at 7 ºC was used in the experiments where Fe2+-oxidation rate and optimum temperature were determined over a temperature range of 2-40 ºC. Two temperature optima of 22.4 ºC and 32.4 ºC were observed. This indicated the presence of both psychrotolerant and/ or mesophilic microorganisms in the culture. This supports the suggestion that A. ferrooxidans was actually A. ferrivorans, or both species were present. The specific oxidation rates for the culture were similar, with 13.5·10-8 and 12.8·10-8 mg Fe2+ cell-1 h-1 for 22.4 ºC and 32.4 ºC, respectively.

The two demonstration-scale bioheaps (17 000 t) at the Talvivaara mine site were operated and monitored by Talvivaara Mining Company for 30 months. After the start-up of heap irrigation, oxidation of pyrrhotite and pyrite increased the heap temperature in central locations up to 90 ºC. In the second winter temperatures inside the heaps decreased being still 80 ºC at the hottest spots. Leach liquor temperatures varied between 60 ºC and 15 ºC over the whole operation period. The target pH of the PLS was 2.0. Inspite of continuous titration pH varied during the 10 months between 3.5 and 3.0 and after that between 3.0 and 2.5.

The bacterial community composition on the heaps was monitored over time from manholes and the leach liquor collection ponds. At the end of the primary bioleach phase (18 months) cell counts were around 106 cells mL-1. Large temperature gradients resulted in the simultaneous presence of mesophilic and thermophilic iron- and sulphur-oxidisers in the heap. In the beginning diversity was broad, but decreased with time. A. ferrooxidans/ ferrivorans SS3 (99%, CP002985) was the dominant bacterium and an unknown bacterium related to clone H70 (91%, DQ328625) was present. After six months of bioheap operation L. ferrooxidans DSM 2705 (98%, X86776) was observed for the first time and it was present thereafter in nearly all samples. Archaea were analysed during the primary leaching phase from leach liquors. Two novel archaea and one archaea related to Thermoplasma acidophilum strain 122-1B2 (91-93%, NR_028235) were detected.

Several ore samples were drilled from the primary bioheaps after one year of bioheap operation. A. ferrooxidans/ A. ferrivorans SS3 (99%, CP002985) was present in nearly all samples. The novel bacterium related to clone H70 (91%, DQ328625) and A. caldus related bacteria (95%, AY427958) was detected from the areas of wide temperature variation. Sb. thermosulfidooxidans strain YN22 (99%, DQ650351) was found from the high temperature zones of the heap. Ferrimicrobium acidiphilum T23 (99%, AF251436) was present in the areas where temperature varied between 20 and 35 ºC. After 18 months of demonstration-scale heap operation, the heaps were reclaimed and restacked to the secondary bioheap. At the secondary leaching phase the community remained steady. A. ferrooxidans/ ferrivorans SS3 (99%, CP002985) dominated and the novel bacterium related to a clone H70 (91%, DQ328625) and L. ferrooxidans DSM 2705 (98-100%, X86776) were present in the leach liquors of secondary phase bioheaps.

Ecological Sanitation - A Logical Choice? The Development of the Sanitation Institution in a World Society

Sustainability, encompassing ecological, economic as well as sociocultural aspects, has become a driving force for many political and administrational decisions. It is no longer enough to follow old practices or rely on profit margins – it is necessary to consider the needs of society and nature in a more holistic way as a larger whole. Sustainability is the key word also in terms of sanitation; ecological sanitation, or ecosan for short, has come to mark the sustainable approach to handling human excreta.

In 2014, there are still approximately 2.5 billion people in the world without access to adequate sanitation; 1.1 billion practice open defecation. Lack of sanitation is often – but not necessarily – linked to lack of clean drinking water and poor hygiene. However, poor wastewater treatment also occurs in more developed countries as well as in times of crisis. In the case of natural disasters, even waterborne sanitation, which is often considered the norm, does not prevent the risk of contamination from pathogens. Ecological sanitation aims at a closed cycle of nutrients and absence of water; dry toilets, composting and urine diversion help to return nutrients back into the soil.

Based on these challenges, it is necessary to examine alternatives to the current toilet institution that considers waterborne sanitation as the norm. This dissertation explores the feasibility of ecological sanitation as a potential alternative to the mainstream option and the aim is to discover which issues affect the development and change of the current waterborne toilet institution. From a multi- and interdisciplinary point of view, the dissertation determines the various aspects affected by ecosan, such as water and environment, health, culture, education, agriculture, business and technology, and from these points of view develops futures scenarios for sustainable sanitation practices. Technology is here defined beyond artefacts and processes encompassing also knowhow as well as the sociotechnical systems of use, including legislation, culture and practices.

The data collected for this research includes expert interviews (n=11), case studies from Ethiopia, Finland, New Zealand and Zambia, and literature review including various policy documents and legislation of the aforementioned case countries to shed light to the current state of ecological sanitation and how it is taken into account from a legal perspective. In addition, a two-round consensus-Delphi survey (n1=44, n2=22) together with theme seminars was conducted among Finnish experts to determine the future potential of ecological sanitation.

Through qualitative data analyses, the potential futures and desirable outcomes are mapped with the help of futures research and environmental scanning. The overall challenge of potentially changing the waterborne toilet institution is discussed in the light of the World Polity Theory – with the understanding that global norms are valid everywhere and that change eventually must start from intergovernmental actors rather than political decision makers.

This research brings more insight to the relatively unknown and overlooked subject of ecological sanitation. The integrated approach offers new insight into sustainable sanitation practices and closed loop approach from view points of the various sectors of society, including social, economic and ecological aspects. The undisputed challenges of inadequate sanitation facilities faced by 2.5 billion people worldwide are generally not recognized in scientific literature, although several invaluable studies have contributed to the field. Still, concrete results for improvement are still required.

The results of this study find that ecological sanitation must be approached from a multidisciplinary point of view in order to understand the variety of sectors impacted by these sustainable practices. As a conclusion it can be stated that the traditional norms in waterborne sanitation are difficult to change but the pressure of limited phosphorus resources and deteriorating or non-existing infrastructure require alternative solutions to the norm. As yet, legislation has generally not allowed or considered the use of human excreta as fertiliser, but practices are slowly changing along with attitudes. Institutions do not change easily but can do so while attitudes, policies and practices all start adopting new ways of operating.

It is possible that in the future ecological sanitation will indeed be accepted as a feasible option along with other sanitation methods. This is supported also by the increasing need for sustainable practices in societies. However, in more daunting futures the lack of closed cycles will lead to shortages in resources as well as the lack of wellbeing in communities without access to sanitation. Thus, the research of sustainable sanitation solution is significant and necessary – also in the future.

Teräsrumpujen uudet korjausmenetelmät: Halkaistu sisäputki, puolipohjaus ja pohjan betonointi

Tässä tutkimuksessa arvioitiin uudentyyppisten korjausmenetelmien soveltuvuutta teräksestä valmistettujen tierumpujen käyttöiän pidentämiseksi. Tutkimuksessa rajauduttiin tarkastelemaan sellaisia korjausmenetelmiä, joita käyttämällä rumpuputken aukon koko pienenee mahdollisimman vähän. Rumpujen korjaaminen on kannattavinta kohteissa, joissa rummun asennussyvyys on suuri tai tien aukikaivaminen aiheuttaa suuret liikenteenjärjestelykustannukset.

Tutkimuksessa on tarkasteltu kolmea uutta menetelmää: halkaistu sisäputki, puolipohjaus ja pohjan betonointi. Näistä kahta ensinnä mainittua kokeiltiin verraten matalalla peitesyvyydellä olevissa rummuissa, mistä johtuen niistä oli mielekästä mitata myös rumpurakenteen mekaanista toimintaa raskaan ajoneuvoyhdistelmän ajaessa mittauskohteen yli. Pohjan betonointimenetelmän koekohteena toimineella rummulla peitesyvyys on sitä vastoin niin suuri, että rumpuputkeen ylittävästä ajoneuvosta mobilisoituvat muodonmuutokset jäävät oletettavasti merkityksettömän pieniksi. Tästä johtuen kyseiseltä koekohteelta kerätyt havainnot rajoittuvat pelkästään korjausrakenteen periaatteen ja toteutuksen dokumentointiin. Niitä kahta koekohdetta, joilla tehtiin mittauksia, tarkasteltiin myös tarkemmin elementtimenetelmään perustuvien mallien avulla.

Kaikki tutkimukseen valikoituneet korjausmenetelmät osoittautuivat rakennettujen koekohteiden perusteella toteuttamiskelpoisiksi. Kahdessa kohteessa kuormituskokeiden perusteella saatujen mittaustulosten perusteella korjausmenetelmät arvioitiin myös rummun mekaanisen toiminnan kannalta toimiviksi ratkaisuiksi. Mittausten avulla todennetut jännitys- ja muodonmuutostasot jäivät verrattain maltillisiksi, vaikka rummun peitesyvyys oli koekohteissa melko pieni.

Aiemmissa rumpuputken mekaanisen toiminnan mallinnuksissa käytetyn PLAXIS 3D-ohjelmiston rinnalla mallinnettiin tässä tutkimuksessa rumpuputkeen syntyviä rasituksia tarkemmin myös ANSYS-ohjelmistolla. Tämän osalta todettiin, että korjatun rumpuputken mekaanista käyttäytymistä ei saatu verifioitua uskottaviksi arvioiduilla materiaaliparametreilla. Suurin yksittäinen laskennallista virhettä aiheuttava tekijä oli ANSYS-ohjelmistossa käytössä ollut materiaalimalli, joka mahdollisti vetojännitysten syntymisen sitomattomiin tien rakennekerroksiin. Tällöin liikennekuormitus ei vaikuta etenkään tierakenteen syvyyssuunnassa tarpeeksi suurena, ja myös rummun yläpintaa rasittava puristusjännitys jää laskentamalleissa liian pieneksi. Tulevia korjausratkaisuja ei siis tutkimuksen tulosten perusteella pystytä verifioimaan pelkästään laskennallisesti tässä tutkimuksessa käytetyllä lähestymistavalla, mikäli rajaudutaan uskottaviksi arvioituihin materiaaliparametreihin tien rakennekerrosten ja pohjamaan osalta. Näin ollen laskennallisten parametrien määrittämisen tueksi tarvitaan tarkempia tietoja joko rumpuputken käyttäytymisestä tai rumpa ympäröivistä maakerroksista.

Rakennusten energiankulutuksen perusskenaario Suomessa 2015-2050

Ilmaston lämpenemistä aiheuttavista kasvihuonekaasupäästöistä noin 80 % on peräisin energian tuotannosta ja kulutuksesta (ml. liikenne), mikä tarkoittaa, että energia- ja ilmastopolitiikka ovat tiivis kokonaisuus. Vuonna 2016 Suomessa valmisteltiin uutta energia- ja ilmastostrategiaa, johon kuuluu myös skenaarioiden valmistelu. Tässä raportissa esitetty työ tukee strategian valmistelutyötä. Raportti jakaantuu kahteen osaan: rakennuskannan energiankäytön ennustamiseen ja puun pienpolton lisäämisen tarkasteluihin. Työssä tehtiin rakennustyypeittäin perusskenaarion mukainen tarkastelu, joka jatkaa tulevaisuuteen energiatilastojen lukuja vuodesta 2015 aina vuoteen 2050. Perusskenaariolla arvioidaan jo päätettyjen ja toimeenpantujen politiikkatoimien vaikutusta tulevaisuuden kehitykseen. Rakennuskannan energiankäytön osalta tehtiin ennuste peruskehityksestä ja lisäksi matalamman talouskasvun ennuste. Energiankulutus on esitetty sekä hankitun energian tasolla että hyötyenergiana. Varsinaisten asuinrakennusten (pientalot, rivi- ja ketjutalot, asuinkerrostalot) hankitun energian määrässä on pieni laskeva trendi, mutta energiantarve pysyy oleellisesti samalla tasolla tarkasteluajanjaksolla. Aurinkolämmön kehitykselle muodostettiin maltillinen lineaariseen kasvuun perustuva ennuste. Toiseksi työssä tarkasteltiin puun pienpolton lisäämisestä aiheutuvia pienhiukkaspäästöjä ja niiden vaikutusta väestöaltistukseen. Laskentaesimerkin perusteella voidaan todeta, että myös modernien, verrattain vähäpäästöisten varaavien takkojen kasvava käyttö lisää hengitysilman pienhiukkaspitoisuuksia.

Modeling of Finnish building sector energy consumption and greenhouse gas emission: specification of POLIREM policy scenario model

Monitoring needs have increased in recent years, and answers to various questions related to the energy use of the building stock are needed faster than before. POLIREM model is a calculation model that assesses the effect of different policy scenarios on the Finnish building stock. The model determines the energy consumption and greenhouse gas emissions, and its purpose is to assist in the reporting and scenario work. The model has a strong linkage with the statistical data, and a top-down approach, which makes the POLIREM different from previous bottom-up style building stock models.

The POLIREM model was originally developed at the Tampere University of Technology in MS excel environment. In this work, the model was converted into a coded version that ensures flexible scenario building, including ease of updating the input data, as well as enabling further integration of new features and/or data sources. This report provides a technical specification of the python-coded scenario model POLIREM.

This report is part of development work to establish national reporting system/evaluation scheme, and fulfils requirements for openness by describing transparently the used evaluation method for building
stock modelling.

Enabling and Integrative Infrastructure Policy: The Role of Inverse Infrastructures in Local Infrastructure Provision with Special Reference to Finnish Water Cooperatives

Infrastructures are necessary to support the functionality of urban communities. Globalization, increased polycentricity, new trends in governance and tightening public budgets have increased interest in alternative ways of providing such infrastructures. One product of this trend is the ‘inverse infrastructure,’ which refers to a modularized, semi-autonomous and user-driven infrastructure that is a result of the self-organization of local actors. In this study, we discuss the nature of such infrastructures and the challenges they pose to local infrastructure policy with special reference to the case of water cooperatives in Finland. Our conclusion is that inverse infrastructures have a potential to contribute to local infrastructure services either as cost-effective alternative or as supplement to large technical systems. Their full utilization requires, however, enabling and integrative infrastructure policy.

Deterioration mechanisms and life cycle of concrete monoblock railway sleepers in Finnish conditions

Thirty eight sleepers aged 30 to 40 years old were removed from Finnish railway lines and were loaded. Twelve new sleepers were also tested. The old sleepers fulfilled most of the requirements specified for the new ones. The old sleepers were also much more resistant to loading than predicted by structural calculations. The purpose of field tests was to establish the role of traffic loads in the life-cycle of sleepers: the actual stresses and moments in sleepers due to traffic loads; the distribution of the load through the underside of the sleeper to the ballast; and the variation in ballast-sleeper reaction on different sections of track in different seasons. Strain changes at the top surfaces of sleepers were measured on tracks while the rail was loaded by passing trains. Ballast-sleeper reactions tended to be concentrated under the rail along a length of sleeper of approximately 350 mm towards the centre of the track. The mean bending moments determined at the rail seat and centre of sleepers were about ±2.5 kNm, and the maximum moments were up to ±10 kNm. The purpose of fatigue loading tests was to analyse the long term properties of the sleepers and the effect of fatigue on the stiffness of sleepers. Several load levels were chosen in order to estimate the significance of the fatigue in a real operating situation. The fatigue limit determined based on the loading tests and the computational limit state of crack formation were clearly higher than the bending moments measured in the field tests.

Dry Toilet Sanitation as an Alternative Solution to the Rural Ethiopia

This paper intended to explore the sanitation situation of the rural Ethiopia and evaluate how the existing situation can welcome dry toilet as an alternative for sanitation. The study was based on the field survey, literature reviews and field observation during November-December of 2012 and 2013, and June 2014. The survey found out that a lot has been done in the area, but it is too early to declare that the question is solved. In terms of DT sanitation policy and promotion intra-ministerial collaborations are improving. Moreover, the traditional use of night soil for the crops that are eaten cooked is an interesting part to be taken into account when considering dry toilet.

Are Finns walking the talk? : Examining the national collaboration process on engineering education for sustainable development five years later

In 2009, the National Collaboration Group for Finnish Engineering Education published a proposal for action on sustainable development (SD). The aim of this paper is to analyze how the three main universities providing engineering education have fulfilled their commitments. The study consists of interviews with key stakeholders supplemented with the analysis of documented material. It is argued that the studied universities are now committed to SD in their strategies. However, a lot of work remains to be done before the strategies are implemented and SD is integrated to all degree programmes. Recommendations for the next steps are presented.

Factors affecting the elimination capacity of a passive methane biofilter

Passive biofilters are used for controlling CH4 emissions from different sources with the help of methanotrophic bacteria. The CH4 elimination capacity of a biofilter can be affected by different factors, such as the structure and composition of the filter material and formation of bacterial exopolymeric saccharides (EPS). Recognising these factors and resolving their effect on the elimination capacity is important for efficient greenhouse gas emission control. Hence, we studied the evolution of the elimination capacity of a passive CH4 biofilter containing soil as low-cost filter material. We aimed at identifying the factors affecting the elimination capacity and tested the effectiveness of a mechanical regeneration method for improving the operation efficiency. A laboratory-scale biofilter containing landfill soil was operated for 148 days. The CH4 removal efficiency reached 70 % in the beginning of the operation (0–7 days), but stabilised at 25 % after 50 days. The filter bed was mixed and loosened twice during the operation. As a result, the glucose content of the soil representing the clogging agent secreted by bacteria (EPS) remained stable throughout the experiment (23 mg gdw-1) and O2 penetrated deeper in the filter bed indicating improved gas diffusion. However, the CH4 removal efficiency did not increase from 25–30 %. The reason for this remained unknown, but the results indicated that soil as filter material was able to maintain its elimination capacity despite the formation of EPS. Mixing was shown to be an effective and necessary method for improving the gas diffusion properties of the filter bed.

Historian hajuista tuoksujen tulevaisuuteen: pääkaupunkiseudun jätevedenpuhdistuksen keskeiset päätökset Espoon näkökulmasta

"From Stinky History to Fragrant Future. Waste water treatment of the metropolitan area - central decisions on the point of view of Espoo is written by Adjunct Professor, PhD Petri S Juuti. The book examines how water and waste water services started and developed in Espoo from the 1950s to the 2000s. Furthermore, it is discussed what are the challenges of the future looked from the point of view of the professionals of the water sector."

Tässä kirjassa käydään läpi pk-seudun jätevedenkäsittelyn historia ja yhteistyövaiheet aina 1950-luvulta 2010-luvulle asti Espoon näkökulmasta. Tutkimuksen pääkysymyksiä ovat mm.:

– Miksi jätevesien puhdistaminen on keskitetty vain yhteen puhdistamoon?
– Miksi Espoossa tehdään ylikunnallista yhteistyötä jätevesienpuhdistuksessa?
– Miten jätevesien puhdistusyhteistyö on alkanut ja muuttunut vuosien varrella?
– Miksi puhdistetaan naapurikuntien jätevesiä?
– Millaista keskustelua jätevedet ovat herättäneet menneisyydessä ja millaista tulevaisuutta koskevaa keskustelua niistä on käyty?

Oikean strategian toteuttamisessa tarvitaan yhteistyötä ja osaavaa johtamista. Espoo on voinut historiassa käyttää omien resurssiensa lisäksi vesihuollossa myös naapurikuntien resursseja. Nyt tarkastelukohteena olevan jätevesienpuhdistuksen osalta tämä on tarkoittanut sitä, että naapurikunnat ovat maksaneet osansa ja osin enemmänkin kuin osansa jätevesiensä puhdistamisesta ja varsinkin Suomenojan jätevedenpuhdistamosta. Näiden lisäresurssien turvin historian saatossa kertyneet resurssit ovat mahdollistaneet nykyisen hyvän tilanteen pitkän tähtäimen strategisten päätösten avulla. Näistä strategisista päätöksistä yksi konkreettisin näyttö ovat jätevesiä koskevat sopimukset naapurikuntien kanssa. Sopimukset ja niiden takana olleet päätökset ovat hyvin kaukonäköisiä ja kaikkia osapuolia sitovia.

Ne osaltaan mahdollistavat, että valittavana on ollut kehityspolkuja, joita kaikkialla ei ole ollut käytössä. Vuoden 2010 alusta alkaen Espoon vesihuolto on toiminut yhdessä pk-seudun organisaatiossa alueen muiden vesilaitosten kanssa, HSY:n organisaation alaisuudessa.

Full scale test structures were constructed in sumemr 1996 to the Ämmässuo landfill to gather experience on quality control during the constructionand long term behviour of mineral liner and combination liners. Actual leachate was used to create the chemical loading and a hydraulic pressure of one meter. The leachate was implemented in October 1996, and the structures were monitored for two years. The structures were continously monitored by temperature and soil moisture sensors installed into the liner. The leachate seeping through the line structure was colledted to the lysimeter basins and further to the lusimeter wells, in which the amount of the water was measured automatically by pressure sensors. In addition, frost penetration and infiltrometer measurements were performed and samples were taken for laboratory tests during the two-year period. The structures were pulled down under control in November 1998.

The role of inorganics in modelling of biomass gasification

In this work, a summary of the research carried out about the role of inorganic elements in biomass gasification is presented. The research work has focused on the catalytic effects of alkali and alkaline earth metals in char gasification. The work has included gasification experiments using thermogravimetric analysis (TGA) and fluidized beds as well as modeling techniques. The results of the research presented in this paper indicate that the laboratory measured TGA reactivity numbers and correlations (including the effect of fuel ash inorganics) are possible to be converted to numbers predicting carbon conversion in a large scale fluidized bed gasification reactor. The model, called Carbon Conversion Predictor, is a relatively simple and transparent tool for the comparison of the gasification reactivity of different fuels in fluidized bed gasification.

Need of Services and Understanding of Service Providers in Water and Sanitation: A Case of Ethiopia

Water and sanitation services are basic requirements for the development of a nation. The provision of these services should necessarily be arranged by the national government through policies, and long-term and short-term plans. Moreover, follow-up of the implementation of principle in policies and plans will determine the service level on the ground. This paper is intended to explore gaps in the policy-making and implementation in the areas of water supply in Ethiopia. Review of Ethiopian water sector policy, universal access plans, growth and transformation plans and other literature are employed to achieve the objective of this paper. Moreover, the experiences of the first author that he acquired during data collection for his doctoral study are taken into account to draw conclusions. Hence, the study shows that standards set at the federal level fail to consider the actual situation on the ground and the experts at implementation level are to interpret some aspects of the policy ambiguously. Therefore, this paper recommends the policy-makers and higher officials to consult the people in charge of putting policies in effect to have contextualized and work for uniform desired- output. Service providers need to understand the notion of the receiving community in order to provide the services that satisfy the users.

To decrease the use of non-renewable natural resources as well as environmental effects of earth-works, natural aggregate materials can be replaced with recycled materials acquired from surplus soil, industrial by-products and waste, etc. When wishing to increase the usage of these reclaimed materials (=“UUMA”-material), the usage must be straightforward for developers, designers and constructors alike. To make this possible, the materials must have design guidelines for their appro-priate applications. They must be productized and CE marked or otherwise authorized, and the con-struction guidelines for the materials must be included in the Finnish general specifications for in-frastructural construction works (InfraRYL). As productization is especially important in increasing the usage of UUMA materials, guidelines for vendors are being drawn that present information on commercializing reclaimed materials to be used in earthworks. The guidelines for productization are being prepared in the Finnish national UUMA2 programme (2013-2017, www.uuma2.fi), which was created to promote the use of recycled materials in earthworks.

Modelling of anisotropic fatigue

A continuum approach for anisotropic fatigue is described. The approach is based on the idea of a moving endurance surface in
the stress space where the movement is described by a back-stress type tensor. The evolution associated with the movement is described by
a rate type equation. In addition, damage accumulation is governed by a rate type evolution equation, thus facilitating its use under arbitrary
complex loading conditions. The main emphasis of this paper is to discuss the possible forms of the endurance surface and pertinent
evolution equations to model high-cycle anisotropic fatigue. Suggestions towards a unified model capturing the low-cycle regime are also
given.

Fungal treatment of landfill mining fine fraction to increase its stability and end-use potential

Landfill mining, i.e. extraction, processing, treatment and recovery of landfilled materials, is conducted to prevent pollution and to recover materials and energy from waste (Krook et al., 2012). On average, half of landfilled waste is material resembling soil, i.e. its fine fraction (FF, < 20 mm) (Kaartinen et al., 2013). The end-use potential of the FF is limited due to its organic matter content, a possible presence of harmful contaminants as well as its stability. The aim of this study was to evaluate if fungal treatment stabilises FF and removes organic contaminants thus allowing an end-use of FF as soil-like material. Basidiomycetous fungi were obtained and maintained according to Valentin et al. (2008) prior to experiments and were screened for their potential to grow in FF originally landfilled between 1967 – 1989. Screening experiments and previous experiences with contaminated soil (Valentin et al. 2008) led to the selection of Phanerochaete velutina for fungal treatment experiments, which were carried out at room temperature for 58 days. Two acryl columns (height 600 mm, radius 75 mm) were filled with 1 – 2 cm layer of gravel at the bottom and 5.8 kg of FF on the top as well as 500 mL of tap water. The fungal column was amended with fungal bark inoculum to the middle of the column. Two ports at the bottom of the columns were used to collect leachate and aerate columns with humidified air at 0.1 L/min, respectively. Carbon dioxide (CO2) production was followed during the experiment with gas chromatography. The columns were covered with aluminium foil to stop germination of seeds present in FF. Total solids and volatile solids (VS) were analysed from FF according to standard SFS 3008. Organic contaminants mentioned in criteria for landfilling were analysed from FF in an accredited laboratory. Aerobic stability of FF was determined by the Oxitop method and anaerobic stability of FF was determined as biochemical methane potential. In less than one month, fungal mycelium was observed throughout the FF in the column inoculated with Phanerochaete velutina while no mycelium was observed in the control column. At this stage the experiment was continued in order to allow fungal mycelium to degrade and produce CO2. Concentrations of mineral oils (C10-C40) and organic matter, measured as VS, were higher in FF than in waste that can be placed to landfills. Mineral oil concentrations exceeded Finnish criteria set for contaminated soil. The aerobic stability of FF was high even initially and it did not increase in control or fungal treatments. Fungal treatment reduced organic matter content of FF and reduced mineral oil concentrations, although the criteria set in legislation could not be met in these experiments.

Influence of Diffusion Barriers on Thermal Ageing Behaviour of Solar Absorber Coatings on Copper

The thermal stability of magnetron sputtered and electroplated solar absorber coatings were investigated at elevated temperatures of 200-500°C. Diffusion barriers of aluminium and nickel were studied towards thermal diffusion of copper substrate atoms.

The diffusion barriers studied were experimental magnetron sputtered Al layers and an industrial electroplated Ni layer between a Cu substrate and an absorber coating. The thicknesses of Al barriers were 0.1 µm and 0.5 µm, and a Ni barrier was 3 µm thick. As absorber coatings, magnetron sputtered chromium-based coatings and industrially electroplated black chromium coatings, were studied. The sputtered absorbers were a 3-layer stack of CrOx/Cr/CrOx with layer thicknesses of 0.05/0.03/0.05 µm, respectively. The electroplated black chromium coating had a thickness of 0.2 µm. Copper was used as a substrate for all of the absorbers studied.

The degradation of the absorber surfaces and influence of diffusion barriers were analysed by optical measurements (solar absorptance with a UV/Vis/NIR spectrophotometer and thermal emittance with a FTIR spectrophotometer), microstructural analyses were performed using a field-emission scanning electron microscope (FESEM). The absorbers were aged by means of heat treatments in a circulating air furnace at 200, 300, 400 and 500°C for two hours. The experimental analyses were performed before and after the ageing studies.

The results showed that without a barrier coating copper substrate atoms can diffuse into the absorber coating and through the coating to the surface of the coating and form CuO islands on the surface. These phenomena degraded optical selectivity of the absorber surface. The diffusion can be prevented or retarded with a diffusion barrier layer between the Cu substrate and the absorber coating. The 3-µm-thick Ni barrier prevented Cu diffusion and retained optical selectivity up to 500°C for two hours and the 0.5-µm-thick Al layer up to 400°C.

Leveraging concepts for environmentally sustainable business management in construction - a focused review

The main objective of this paper is to advance applied conceptual knowledge about environmentally sustainable business management (BM) in construction. Environmentally sustainable BM is herein defined to encompass the utilization and development of natural resources in ways which are compatible with the maintenance of these resources, and with the conservation of the natural and built environments, for current and future generations. In principle, concept designers can incorporate environmental sustainability into their BM concepts as a dimension, an element, or an attribute of managing, or as a criterion in decision making. Readily, the 71 construction-related BM concepts have been published between 1990 and 2013. A focused review resulted in the expected findings, i.e., only the 11 (15%) construction-related BM concepts have been designed along the environmental sustainability dimension. Thus, it is posited that high-sustainability BM concepts be designed by coupling environmental sustainability with the three other necessary dimensions, i.e., content-free frames of reference on BM, schools of thought on generic BM, and focal contexts in construction, respectively. In turn, CIB-related researchers may adopt these couplings and engage themselves with cross-disciplinary BM conceptualization programs in collaboration with farsighted business managers in construction.

Technical suitability of the fine fraction of municipal solid waste incineration bottom ash to the landfill capping liner

To protect the natural aggregates and promote the circular economy the suitable secondary aggregates have been studied intensively in last decades in Finland. One promising secondary aggregate is bottom ash from the municipal solid waste incineration (MSWI) process.
The municipal incinerator bottom ash (MIBA, also called MSWI BA) contains heavy metals and other contaminants limiting its environmental acceptability. The fines contain typically the highest concentrations of contaminants. The portion of inert particles such as rock, glass and mineral waste is higher in coarser fractions.
The aim of the study was to assess the suitability of the fines of MIBA to the mineral liner in landfill capping. Based on the environmental permit, the target permeability value for capping liner is k ≤ 1 · 10-9 m/s. The permeability of the fines of MIBA is typically around 1 · 10-7 m/s when well compacted. In order to achieve the required permeability, bentonite or other additivies are needed. The grains are porous and the pH is high, typically 10-12, which effect on the amount of bentonite required. In addition, the MIBA contain high concentrations of diluting chlorides, sulfides and calcium, which decrease the swelling properties of the bentonite. The swelling capacity of bentonite decreases when permeating aggressive leakages with high cation concentration. Therefore a special polymer treated bentonite were chosen for the tests. The addition of superabsorbent polymers, which have much higher resistance to aggressive leakages, greatly improve the performance and self-healing capacity of bentonite.
First, laboratory tests were performed to estimate the proper amount and quality of the bentonite needed to achieve the permeability required. Two bentonite types were tested, the common natural bentonite and a special polymer modified bentonite produced by Cetco. The swelling index of both types of bentonite were tested by a eluate of MIBA. Several permeability tests were performed to evaluate the effect of dry density, bentonite quality and dose, and portion of coarser grains (2-5 mm).
After laboratory testing, a test area was constructed on an old waste fill to the Ämmässuo. During the construction, it was noticed that the water content effects significantly on the compaction result. The mineral liner was covered by a 1,5 mm thick LLDPE geomembrane and protective geotextile. The liner structure is covered only by a 0,5 m thick drainage layer from crushed rock. No surface layer were constructed.
After one year, the liner was exposed and studied. The quality of the structures, especially the mineral liner were visually evaluated and gas emissions were measured from the surface. The density of the layer was measured by volymeter and troxler and the water content and permeability were measured in laboratory. Based on the visual inspection the surface of the mineral liner was smooth, and the layer homogenious and hardened

Operationalising the right to water and sanitation and gender equality via appropriate technology in rural Nepal

Can a tap, a squat toilet, or an improved cooking stove – all simple rural technologies – make a contribution to achieving human rights and the Sustainable Development Goals (SDGs)? What are the ‘soft’ elements, beyond the technology, that are needed? This article explores how, the principles of human rights based approach (HRBA), gender equality and social inclusion (GESI) are mainstreamed and operationalized through two bilateral rural water projects in Nepal - the Finland and Nepal-funded Rural Water Supply and Sanitation Project in Western Nepal (RWSSP-WN) and the Rural Village Water Resources Management Project (RVWRMP). The projects utilise a combination of hands-on technical assistance, community participation and appropriate technologies to achieve the Right to Water and Sanitation, as well as making a contribution to the SDGs. The technologies include water supply systems; renewable energy, including micro-hydropower schemes, improved cooking stoves, improved water mills and hydraulic ram pumps; as well as water seal toilets. However, simply providing technology is not enough. It is critical that it is applied within a strong planning and implementation framework, integrated in local government and communities, but supported with skilful facilitation. This case study focuses on the results achieved and critical lessons learned regarding gender equality and empowerment (SDG 5), and access to water and sanitation (SDG 6). The lessons learned, including the important role of the technical staff in the project modality, are valuable for planners and implementers of water and sanitation projects elsewhere.

Unipoli Green - Four Universities Working Together for Sustainability

This paper introduces the Finnish context for promoting sustainable development in higher education and describes and analyzes the development of cooperation in Tampere, Finland: its benefits, challenges and limitations. The expectations for universities to promote sustainable development are rising while the resources for sustainability work are scarce. In Tampere there are four universities, Police University College, Tampere University of Applied Science, Tampere University of Technology and University of Tampere, educating and employing over 40,000 people. Promoting sustainability is in different phases at each of these universities. The coordinators of sustainable development in these universities met in spring 2014 and agreed on information sharing and cooperation in the form of concrete events and thematic days. This initiative was supported by the existence of the universities’ cooperation platform UNIPOLI. Later the cooperation has found three major fields: (1) awareness raising, (2) sharing information and influencing management and (3) curriculum development. Possibility of sharing knowledge and experiences and building a community has enabled more efficient actions in all these fields, but the vague mandate of network has caused confusion and hindered realization of some ideas.
