Water Supply and Sanitation in a Green Economy Society: The Case of Finland

A green economy specifically considers the welfare of the environment and is closely aligned with sustainable development—in both, the use of natural resources should be less than their natural production. In this article, the concept of a green economy is discussed from the viewpoint of water services, a crucial part of a sustainable society, with the objective of enhancing knowledge about sustainable and resilient water services that will meet society’s future demands. Drawing from a literature review and a stakeholder workshop attended by 68 experts, it seeks to answer three research questions: (a) What are appropriate and sustainable urban water supply and sanitation policies for a society that is adopting the basic principles of a green economy? (b) What should be the role of water supply and sanitation in a green and circular economy and what are the current challenges to meeting this objective? and (c) What actions are needed in the Finnish water and sanitation services (WSS) sector to effectively meet the requirements of a green and circular economy? The results are applied to the specific case of Finland, and recommendations and conclusions for the Finnish society and its water services are presented.

Viewpoint - Paradigm Shift of Water Services in Finland: From Production Mentality to Service Mindset

In this article, the current management paradigm of water services in Finland is conceptualised. For this purpose, the managers of water utility in ten Finnish municipalities were interviewed. Consequently, the ways in which water services are perceived and managed are also described in this article. In addition, it is argued that the current paradigm produces systemic behaviour that can be considered to give rise to unsustainable ways of developing water services. Based on the problems of the current paradigm, an alternative paradigm is drafted that rethinks the value-creation logic. This alternative paradigm implies that one should be aware of the interactions between systems in which water services play a crucial role, and act accordingly.

Vapor phase processing of α-Fe2O3 photoelectrodes for water splitting: An insight into the structure/property interplay

Harvesting radiant energy to trigger water photoelectrolysis and produce clean hydrogen is receiving increasing attention in the search of alternative energy resources. In this regard, hematite (alpha-Fe2O3) nanostructures with controlled nano-organization have been fabricated and investigated for use as anodes in photoelectrochemical (PEC) cells. The target systems have been grown on conductive substrates by plasma enhanced-chemical vapor deposition (PE-CVD) and subjected to eventual ex situ annealing in air to further tailor their structure and properties. A detailed multitechnique approach has enabled to elucidate between system characteristics and the generated photocurrent. The present alpha-Fe2O3 systems are characterized by a high purity and hierarchical morphologies consisting of nanopyramids/organized dendrites, offering a high contact area with the electrolyte. PEC data reveal a dramatic response enhancement upon thermal treatment, related to a more efficient electron transfer. The reasons underlying such a phenomenon are elucidated and discussed by transient absorption spectroscopy (TAS) studies of photogenerated charge carrier kinetics, investigated on different time scales for the first time on PE-CVD Fe2O3 nanostructures.

The present study valorized Finnish mining tailings waste to identify opportunities for the use of ceramics technologies. On the basis of their mineralogical and chemical contents, the five selected tailings wastes represented felsic mining tailings (FMT) rich in quartz and alkali feldspars, mining tailings dominated by Mg- and Fe-bearing minerals (MgFeMT), and mining tailings rich in carbonate minerals (CMT). Preliminary pilot studies indicated that the FMT materials are potential secondary raw materials for mullite-type ceramics. An Al additive was needed, since the Al2O3 content of the studied tailings was too low for mullitization. In addition, carbonate-bearing tailings with Ca silicates can be applicable for chemically bonded phosphate ceramic (CBPC) synthesis. Based on a literature review, FMT are viable source materials for the production of geopolymers, but a high initial Si:Al ratio (in quartz-rich FMT) may lead to partial geopolymerization. Preliminary results from the geopolymerization of pre-heated phlogopite mica mixed with metakaolin gave promising findings, with the formation of a geopolymer having good compressive strength. The findings support the viability of MgFeMT materials rich in phlogopite mica for the production of alkali-activated ceramics.

UV-Blocking Synthetic Biopolymer from Biomass-Based Bifuran Diester and Ethylene Glycol

A furan-based synthetic biopolymer composed of a bifuran monomer and ethylene glycol was synthesized through melt polycondensation, and the resulting polyester was found to have promising thermal and mechanical properties. The bifuran monomer, dimethyl 2,2′-bifuran-5,5′-dicarboxylate, was prepared using a palladium-catalyzed, phosphine ligand-free direct coupling protocol. A titanium-catalyzed polycondensation procedure was found effective at polymerizing the bifuran monomer with ethylene glycol. The prepared bifuran polyester exhibited several intriguing properties including high tensile modulus. In addition, the bifuran monomer furnished the polyester with a relatively high glass transition temperature. Films prepared from the new polyester also had excellent oxygen and water barrier properties, which were found to be superior to those of poly(ethylene terephthalate). Moreover, the novel polyester also has good ultraviolet radiation blocking properties.

Utilizing Gelatinized Starchy Waste from Rice Noodle Factory as Substrate for L(+)-Lactic Acid Production by Amylolytic Lactic Acid Bacterium Enterococcus faecium K-1

To valorize starchy waste from rice noodle factory, bioconversion of gelatinized starchy waste (GSW) to value-added product as L(+)-lactic acid, the monomer for polylactate synthesis, was investigated using amylolytic lactic acid bacterium, Enterococcus faecium K-1. Screening for appropriate nitrogen source to replace expensive organic nitrogen sources revealed that corn steep liquor (CSL) was the most suitable regarding high efficacy for L(+)-LA achievement and low-cost property. The successful applying statistic experimental design, Plackett-Burman design incorporated with central composite design (CCD), predicted the maximum L(+)-LA of 93.07 g/L from the optimized medium (OM) containing 125.7 g/L GSW and 207.3 g/L CSL supplemented with CH3COONa, MgSO4, MnSO4, K2HPO4, CaCl2, (NH4)2HC6H5O7, and Tween80. Minimizing the medium cost by removal of all inorganic salts and Tween80 from OM was not an effect on L(+)-LA yield. Fermentation using the optimized medium without minerals (OM-Mi) containing only GSW (125.7 g/L) and CSL (207.3 g/L) in a 10-L fermenter was also successful. Thinning GSW with α-amylase from Lactobacillus plantarum S21 increased L(+)-LA productivity in the early stage of 24-h fermentation. Not only showing the feasible bioconversion process for GSW utilizing as a substrate for L(+)-LA production, this research also demonstrated the efficient model for industrial starchy waste valorization.

Utility–Customer Communication: The Case of Water Utilities

The aim of this article is to shed light on the theory and praxis of utility stakeholder communication. Our general research objective is to contrast citizens’ experiences of utility-specific information needs with the views of communication managers of municipal water utilities. Empirical data for the study were gathered using two methods. Citizens’ views were gathered from street interviews in several Finnish middle-sized cities, whereas the views of communication professionals of municipal water utilities were collected via email-based survey. Empirical analysis shows that one-way communication has its relevance, and it should actually be improved most notably in exceptional situations, such as water supply disruptions. More profound changes in customer communication require, however, that utilities support customers’ strive for sustainable and economical water consumption. The overall challenge to utilities is to get closer to the everyday needs of their customers and to develop new communication culture to support such an endeavor.

Use of factorial experimental design to study the effects of iron and sulfur on growth of Scenedesmus acuminatus with different nitrogen sources

The aim of this study was to determine the combined effects of iron and sulfur on microalgal biomass concentration and removal efficiency of nitrogenous compounds using factorial design. Scenedesmus acuminatus (currently accepted name Tetradesmus lagerheimii) was separately cultivated in batch photobioreactors using modified N-8 media with two nitrogen sources, nitrate, and ammonium. To study the interaction effect between iron and sulfur and to reduce the total number of experimentally studied combinations, a factorial design was used. Three iron (0.1, 1, and 1.9 mg L−1) and three sulfur concentrations (3.7, 20, and 35.8 mg L−1) were employed to the modified N-8 media in this study. The results show that the final microalgal biomass concentration and nitrogen removal efficiency were more sensitive to the changes in iron and sulfur concentrations in the media with nitrate than with ammonium possibly because of the different assimilation mechanisms used by microalgae for these two nitrogen sources. The created models demonstrated that iron had a statistically significant effect on the microalgal biomass concentration and nitrate removal efficiency while sulfur did not. In addition, the interaction effect between iron and sulfur was not significant on microalgal biomass concentration and nitrogen removal. In synthetic medium with nitrate as nitrogen source, the highest microalgal biomass concentration was obtained with 1.0 mg L−1 iron and 35.8 mg L−1 sulfur.

Use of diluted urine for cultivation of Chlorella vulgaris

Our aim was to study the biomass growth of microalga Chlorella vulgaris using diluted human urine as a sole nutrient source. Batch cultivations (21 days) were conducted in five different urine dilutions (1:25-1:300), in 1:100-diluted urine as such and with added trace elements, and as a reference, in artificial growth medium. The highest biomass density was obtained in 1:100-diluted urine with and without additional trace elements (0.73 and 0.60 g L(-1), respectively). Similar biomass growth trends and densities were obtained with 1:25- and 1:300-diluted urine (0.52 vs. 0.48 gVSS L(-1)) indicating that urine at dilution 1:25 can be used to cultivate microalgal based biomass. Interestingly, even 1:300-diluted urine contained sufficiently nutrients and trace elements to support biomass growth. Biomass production was similar despite pH-variation from < 5 to 9 in different incubations indicating robustness of the biomass growth. Ammonium formation did not inhibit overall biomass growth. At the beginning of cultivation, the majority of the biomass consisted of living algal cells, while towards the end, their share decreased and the estimated share of bacteria and cell debris increased.

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.

Understanding sustainable development in Finnish water supply and sanitation services

Water supply and sanitation services are essential to human and environmental well-being. Globally one of the biggest challenges to sustainable development is lack of access to improved water supply and sanitation services. Yet it is less obvious what sustainable development means in countries with high coverage of these services. In this article sustainable development is explored from the perspective of Finnish water supply and sanitation services. The study consists of eight semi-structured interviews with water sector experts and their views are analysed in relation to literature. In this article sustainable development is understood as a learning process and dialogue of values. The interviewed water sector experts primarily perceive sustainable development from an environmental point of view, and treat it in a rationalistic and mechanistic manner. Challenges are tackled by technological fixes, such as improving energy and material efficiency. It is argued in this paper that this kind of approach undermines the complexity and dynamicity of sustainable development and can suppress learning. Sustainable development is mostly explored only from the perspective of water services, although some of the interviewees recognise their role for wider societal development. Interaction and dialogue between water sector experts and the community regarding sustainable development is lacking or skills to accomplish this interaction are inadequate.

Transient–state operation of an anoxic biotrickling filter for H2S removal

The application of an anoxic biotrickling filter (BTF) for H2S removal from contaminated gas streams is a promising technology for simultaneous H2S and NO3− removal. Three transient–state conditions, i.e. different liquid flow rates, wet–dry bed operations and H2S shock loads, were applied to a laboratory–scale anoxic BTF. In addition, bioaugmentation of the BTF with a H2S removing–strain, Paracoccus MAL 1HM19, to enhance the biomass stability was investigated. Liquid flow rates (120, 60 and 30 L d−1) affected the pH and NO3− removal efficiency (RE) in the liquid phase. Wet–dry bed operations at 2–2 h and 24–24 h reduced the H2S elimination capacity (EC) by 60–80%, while the operations at 1–1 h and 12–12 h had a lower effect on the BTF performance. When the BTF was subjected to H2S shock loads by instantly increasing the gas flow rate (from 60 to 200 L h−1) and H2S inlet concentration (from 112 (± 15) to 947 (± 151) ppmv), the BTF still showed a good H2S RE (>93%, EC of 37.8 g S m–3 h–1). Bioaugmentation with Paracoccus MAL 1HM19 enhanced the oxidation of the accumulated S0 to sulfate in the anoxic BTF.

Towards the EU emissions targets of 2050: optimal energy renovation measures of Finnish apartment buildings

Member countries of the European Union have released targets to reduce carbon dioxide emissions by 80% by the year 2050. Energy use in buildings is a major source of these emissions, which is why this study focused on the cost-optimal renovation of Finnish apartment buildings. Apartment buildings from four different construction years (pre-1976, 1976–2002, 2003–2009 and post-2010) were modelled, using three different heating systems: district heating, ground-source heat pump and exhaust air heat pump. Multi-objective optimisation was utilised to find the most cost-effective energy renovation measures. Most cost-effective renovation measures were ground-source heat pumps, demand-based ventilation and solar electricity. Additional thermal insulation of walls was usually too expensive. By performing only the cost-effective renovations, the emissions could be reduced by 80%, 82%, 69% and 68%, from the oldest to the newest buildings, respectively. This could be done with the initial investment cost of 296, 235, 115 and 104 €/m2, respectively.

Towards bioproduction of poly-α-olefins from lignocellulose

Bioprocesses involving more than one species can alleviate restrictions posed by limited substrate range of single species. Coupled, multistage cultures can be useful when heterogeneous substrates, such as lignocellulosic biomass, are exploited. Here, microbial production of α-olefins (C11) from lignocellulosic substrates, namely cellulose and technical lignin, was investigated. A two-stage culture with cellulose fermentation to organic acids by Clostridium cellulolyticum and subsequent upgrading of the organic acids to 1-undecene by engineered Acinetobacter baylyi ADP1 was established. As a result, A. baylyi ADP1 synthesised 107 μg L-1 of 1-undecene from cellulose. Additionally, ligninolytic effects by A. baylyi ADP1 on softwood were confirmed and downstream processing for continuous 1-undecene collection was introduced. In addition, the synthesis of poly-α-olefin trimers (C33) by the oligomerization of 1-undecene was demonstrated. This study demonstrates the potential of integrated multistage processes in treating challenging substrates.

To fractionate municipal solid waste incineration bottom ash: Key for utilisation?

For the past decade, the Finnish waste sector has increasingly moved from the landfilling of municipal solid waste towards waste incineration. New challenges are faced with the growing amounts of municipal solid waste incineration bottom ash, which are mainly landfilled at the moment. Since this is not a sustainable or a profitable solution, finding different utilisation applications for the municipal solid waste incineration bottom ash is crucial. This study reports a comprehensive analysis of bottom ash properties from one waste incineration plant in Finland, which was first treated with a Dutch bottom ash recovery technique called advanced dry recovery. This novel process separates non-ferrous and ferrous metals from bottom ash, generating mineral fractions of different grain sizes (0–2 mm, 2–5 mm, 5–12 mm and 12–50 mm). The main aim of the study was to assess, whether the advanced bottom ash treatment technique, producing mineral fractions of different grain sizes and therefore properties, facilitates the utilisation of municipal solid waste incineration bottom ash in Finland. The results were encouraging; the bottom ash mineral fractions have favourable behaviour against the frost action, which is especially useful in the Finnish conditions. In addition, the leaching of most hazardous substances did not restrict the utilisation of bottom ash, especially for the larger fractions (>5 mm). Overall, this study has shown that the advanced bottom ash recovering technique can be one solution to increase the utilisation of bottom ash and furthermore decrease its landfilling in Finland.

Tighter contracts or more trust? Outsourcing in Finnish water utilities

This article discusses the outsourcing of water utility operations and the prerequisites for successful partnerships between water utilities and external service providers. A questionnaire survey in Finland indicated that the outsourcing of various water utility operations will increase in the future. This trend includes great opportunities to utilize the best features of external service providers and efficiently develop the water services sector. However, the outsourcing also includes risks because there is a lack of trust between water utilities and private companies. Therefore, “hard,” rigid contracts are preferred to reduce the uncertainty in outsourcing such undertakings. In uncertain conditions, this approach may not be an effective and fruitful development path in the long term. If relationships are more trust based, uncertainty can actually strengthen these relationships. Thus, more attention should be paid to building trust instead of intensively attempting to reduce uncertainty.

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.

The potential of electric trucks – An international commodity-level analysis

Development of battery technology is making battery electric heavy duty trucks technically and commercially viable and several manufacturers have introduced battery electric trucks recently. However, the national and sectoral differences in freight transport operations affect the viability of electric trucks. The aim of this paper is to develop a methodology for estimating the potential of electric trucks and demonstrate the results in Switzerland and Finland. Commodity-level analysis of the continuous road freight survey data were carried out in both countries. As much as 71% of Swiss road freight transport tonne-kilometers may be electrified using battery electric trucks but Finland has very limited potential of 35%, due to the use of long and heavy truck-trailer combinations. Within both countries the electrification potential varies considerably between commodities, although in Finland more so than in Switzerland. Commodities which are constrained by payload volume rather than weight and are to large extent carried using medium duty or <26t rigid trucks trucks seem to provide high potential for electrification even with the current technology. Electric trucks increase the annual electricity consumption by only 1–3%, but truck charging is likely to have a large impact on local grids near logistics centres and rest stations along major roads. A spatial analysis by routing the trips reported in the datasets used in this study should be carried out. Future research should also include comparison between the alternate ways of electrifying road freight transport, i.e. batteries with charging, batteries with battery swapping and electrified road systems.

The potential of biomethane in replacing fossil fuels in heavy transport-a case study on Finland

Electrification is a frequently discussed solution for reducing transport related carbon dioxide emissions. However, transport sectors such as aviation and heavy-duty vehicles remain dependent on on-board fuels. Here, biomethane is still a little exploited solution, and the case of heavy-duty vehicles is particularly underappreciated despite the recent technical advances and potentially notable emission reductions. This paper discusses the potential of biomethane in heavy-duty road transport in the case of Finland, where the utilization rate is low compared to the technical potential. To this end, the potential of biomethane production through both anaerobic digestion and gasification was calculated in three scenarios for the heavy-duty transport fleet, based on the literature values of biomethane potential and truck class fuel consumption. The authors find that approximately half of the heavy-duty transport in Finland could be biomethane fueled by 2030. The estimated production costs for biomethane (81-190 €/MWh) would be competitive with the current consumer diesel price (152 €/MWh). Utilizing the total biomethane potential in heavy-duty transport would furthermore decrease the respective carbon dioxide emissions by 50%. To accelerate the transition in the heavy-duty transport sector, a more comprehensive political framework is needed, taking into account both production and consumption.

The most difficult at-fault fatal crashes to avoid with current active safety technology

Objective: We studied which current fatal at-fault crashes would occur despite the most advanced current active safety devices (up to SAE level 2 of driving automation) and how frequent these crashes would be.
Methods: We carried out a cross-sectional study of passenger cars that were first registered during the period 1st January 2010 to 31st December 2017 in Finland. To gain the true exposure for these cars, we accessed the national Vehicular and Driver Data Register to obtain the mileage information and the registration count for the study period of 2010-17. Similarly, we accessed the registry of Finnish road accident investigation teams and included all fatal at-fault crashes among the cars in our study for the same period. We used a real world reference technology for each active safety system in our analysis and chose one car brand as an example. This gave us exact system specifications and enabled testing the operation of the systems on the road. We performed field tests to gain further information on the precise operation of the safety systems in different operating conditions. Finally, we gathered all information on the studied active safety systems and analyzed the investigated at-fault fatal crashes case-by-case using our four level method.
Results: Cars in our study were the primary party in 113 investigated fatal accidents during the years 2010-17. In 87 of the accidents, the leading cause of death was the injuries due to the crash, and these cases were classified as “unavoidable” (n = 58, 67 %), “avoidable” (n = 26, 30 %) or unsolved (n = 3, 3 %). Of the 58 “unavoidable” crashes 21 (36 %) were suicides, 21 (36%) involved active driver input which would have prevented the safety system operation, 15 (17 %) featured circumstances beyond the safety system performance and in one loss-of-control crash the driver had disabled the relevant safety system (electronic stability control). The registration years of the cars in our study (2010-17) totaled 3,772,864 and during this period, the cars travelled 75.9 billion kilometers. The crash incidence of the “unavoidable” at-fault fatal crashes was 0.76-0.80 fatal crashes per billion kilometers and 15-16 fatal crashes per million registration years.
Conclusions: We calculated a crash incidence for the “unavoidable” crashes which was 20–27% smaller than the observed crash rate of ESC-fitted passenger cars in our previous study. We concluded that suicides, active driver input until the crash, and challenging weather and road conditions are the most difficult factors for current active safety systems. Our analysis did not account for issues such as system usability or driver acceptance and therefore our results should be regarded as something that is currently theoretically achievable. However, the observed incidence is a good reference for automated driving development and the crash rate of automated cars.

The effect of torrefaction on the chlorine content and heating value of eight woody biomass samples

This study examined and compared the effect of torrefaction on the heating value, elementary composition, and chlorine content of eight woody biomasses. The biomass samples were torrefied in a specially constructed batch reactor at 260 °C for 30, 60, and 90 min. The original biomasses as well as the solid, liquid, and gaseous torrefaction reaction products were analyzed separately. The higher heating values (HHV) of dry samples increased from 19.5–21.0 MJ  kg−1 to 21.2–23.2 MJ  kg−1 during 60 min of torrefaction. In all samples, the HHV increased 9 % on average. Furthermore, the effect of torrefaction time on the biomass HHV was studied. Measurements showed that after a certain point, increasing the torrefaction time had no effect on the samples' HHV. This optimal torrefaction time varied considerably between the samples. For more reactive biomasses, i.e., birch and aspen, the optimal torrefaction time was close 30 min whereas the HHV of less reactive biomasses, e.g., stumps, increased markedly even after a 60-min torrefaction. Another significant observation was that torrefaction reduced the chlorine content of the biomass samples. The chlorine concentration of the solid product dropped in most samples from the original by half or even as much as 90 %. The highest relative chlorine decrease was observed in the Eucalyptus dunnii sample, which also had the highest chlorine content of all the studied biomasses. The relative carbon content of the biomass samples increased during torrefaction as the average elementary composition changed from CH0.123O0.827 to CH0.105O0.674 after a 60-min torrefaction.

The Effect of Phosphorus Exposure on Diesel Oxidation Catalysts-Part II: Characterization of Structural Changes by Transmission Electron Microscopy

Phosphorus poisoning and its effect on the diesel oxidation catalysts morphology was studied by transmission electron microscopy (TEM). The studied catalyst samples were PtPd or Pt supported on the alumina-based washcoat including additives. The laboratory-scale phosphorus exposures were carried out with two different phosphorus concentrations. The cross-sectional TEM samples were prepared from the fresh and phosphorus-treated catalysts. After phosphorus exposures, significant structural changes were observed compared to the fresh catalysts. The shape of the noble metal particles had changed from irregular to more spherical-shaped particles. In addition, phosphorus was detected throughout the catalyst TEM samples but the amount varied depending on the local composition of the support. Phosphorus accumulated mainly in the alumina-containing areas of the support and indications of dense and amorphous aluminium phosphates were found. Based on the results gained, cross-sectional TEM characterization is essential to observe these kinds of morphological changes in the catalysts caused e.g. by phosphorus exposures. In addition, cross-sectional TEM samples are needed to study the effect of local variation in the support composition on the phosphorus accumulation.

The Effect of Phosphorus Exposure on Diesel Oxidation Catalysts-Part I: Activity Measurements, Elementary and Surface Analyses

The effects of phosphorus poisoning on the activity of PtPd and Pt diesel oxidation catalysts and on the activity of the support material were investigated using the gas phase laboratory-scale-aging procedure. The catalysts were treated using two different phosphorus concentrations (0.065 and 0.13 mol/L (NH4)(2)HPO). The deactivation was studied by inductively coupled plasma optical emission spectroscopy, electron microscopy, X-ray diffractometry, X-ray photoelectron spectrometry and Fourier-transform infrared reflectance, N-2-physisorption, and activity measurements with CO, C3H6 and NO. The amount of accumulated phosphorus was higher on the Pt catalyst surface than on the PtPd catalyst and significantly higher on the surface of the bare support material. Phosphorus concentration was uniform throughout the support layer (down to the 10 mu m), and phosphorus was found as phosphate, although it can also form compounds like AIPO(4) with the support. The treatment with low phosphorus concentration was found to have a clear deactivation effect only for C3H6 oxidation activity on PtPd catalysts above 200 degrees C. The treatment with high phosphorus concentration significantly decreased the activity of both the PtPd and Pt catalysts. In particular, the C3H6 and NO oxidation activities of the fresh and P-treated Pt catalysts were higher than those of the PtPd catalysts for the entire temperature range.

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.

The effect of anode potential on bioelectrochemical and electrochemical tetrathionate degradation

The effect of poised anode potential on electricity production and tetrathionate degradation was studied in two-chamber flow-through electrochemical (ES) and bioelectrochemical systems (BES). The minimum anode potential (vs. Ag/AgCl) for positive current generation was 0.3 V in BES and 0.5 V in the abiotic ES. The anode potential required to obtain average current density above 70 mA m-2 was 0.4 V in BES and above 0.7 V in ES. ES provided higher coulombic efficiency, but the average tetrathionate degradation rate remained significantly higher in BES (above 110 mg L-1 d-1) than in the abiotic ES (below 35 mg L-1 d-1). This study shows that at anode potentials below 0.7 V, the electrochemical tetrathionate degradation is only efficient with microbial catalyst and that significantly higher tetrathionate degradation rates can be obtained with bioelectrochemical systems than with electrochemical systems at the tested anode potentials.

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.

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

Sustainable nutrients recovery and recycling by optimizing the chemical addition sequence for struvite precipitation from raw swine slurries

Livestock farming contributes heavily to nitrogen (N) and phosphorus (P) flows into the environment, a major cause of eutrophication of coastal and freshwater systems. Furthermore, the growing demand for N-P fertilizers is increasing the emission of anthropogenic reactive N into the atmosphere and the depletion of the current P reserves. Therefore, it is essential to minimize the anthropogenic impact on the environment and recycle the wasted N-P for agricultural reuse. This study focused on enhancing struvite (MgNH4PO4*6H2O) precipitation from raw swine slurries in batch and laboratory-scale reactors. Different chemical addition sequences were evaluated, and the best removal efficiency (E%) was obtained when the chemicals were mixed before the precipitation process. Struvite was detected at a pH as low as 6 (E%N-P∼50%), and high E%N-P was found at pH 7–9.5 (80–95%). Furthermore, air stripping was used in place of NaOH to adjust pH, returning the same efficiency as if only alkali had been used. XRD and FE-SEM analysis of the precipitate showed that the recovered struvite was of high purity with orthorhombic crystalline structure and only trace amounts of impurities from matrix organics, co-precipitation products (CaO and amorphous calcium-phosphates), and residuals of added chemicals (MgO).

Subpicosecond to Second Time-Scale Charge Carrier Kinetics in Hematite-Titania Nanocomposite Photoanodes

Water splitting with hematite is negatively affected by poor intrinsic charge transport properties. However, they can be modified by forming heterojunctions to improve charge separation. For this purpose, charge dynamics of TiO2:alpha-Fe2O3 nanocomposite photoanodes are studied using transient absorption spectroscopy to monitor the evolution of photogenerated charge carriers as a function of applied bias voltage. The bias affects the charge carrier dynamics, leading to trapped electrons in the submillisecond time scale and an accumulation of holes with a lifetime of 0.4 +/- 0.1 s. By contrast, slower electron trapping and only few long-lived holes are observed in a bare hematite photoanode. The decay of the long-lived holes is 1 order of magnitude faster for the composite photoanodes than previously published for doped hematite, indicative of higher catalytic efficiency. These results illustrate the advantages of using composite materials to overcome poor charge carrier dynamics, leading to a 30-fold enhancement in photocurrent.

Students’ Perceived Priorities on Water as a Human Right, Natural Resource, and Multiple Goods

s often noted, water is one of the most critical natural resources in the world—one we must take care of so that future generations can enjoy safe water. This study specifically explores university-level water and environmental students’ views on perceived priorities on water. The recent debate on water policy and its complexity is first reviewed, followed by a study on how students perceived water through six predetermined criteria. Interactive learning events (n = 241) were arranged worldwide in 2011–2015 in seven countries and one region: Finland, Latvia, South Africa, Brazil, Mexico, Sri Lanka, USA, and Southern Africa region. The relative distribution of the criteria totaling 100% were as follows: Basic human right 31%, natural resource 25%, economic good 15%, public and social good both 11%, and cultural good 7%. The views did not substantially differentiate despite the different socio-economic conditions. Yet, basic human right should be interpreted wisely remembering environmental, economic, and other realities. Here, the target group consisted of water and environmental students, and it would be very interesting to conduct a comparative study among students in other fields (sociology, economics, etc.). On the whole, we should further analyze the value of water and its priorities to make it easier to manage water resources in the future.

Struvite precipitation in raw and co-digested swine slurries for nutrients recovery in batch reactors

The release of nitrogen (N) and phosphorus (P) from agro-industrial sources is a major environmental concern. Furthermore, the scarcity of mineable P and the growing demand for food worldwide necessitate that we find an alternative P source. This study applied struvite precipitation for N-P recovery to slurries with high levels of organics and ammonia to achieve environmental protection from excessive nutrients diffusion and to generate a sustainable P source. Batch tests were carried out on raw and co-digested swine slurries to study the feasibility of struvite precipitation and the effect of several parameters, including pH, reaction time, competing ions (Ca<sup>2+</sup>, K<sup>+</sup>), total solids (TS), and alkalinity. The batch assays with raw swine slurries showed high N-P removals (up to 80%), while the anaerobic liquor returned lower recovery efficiency due to the high solids and alkali content. Struvite crystallization was detected at pH values as low as 6, and the characteristics of the recovered struvite matched those of the theoretical. Slight co-precipitation of calcium-phosphates occurred and was dependent on the Ca<sup>2+</sup>/Mg<sup>2+</sup> ratio rather than on varying pH values. Struvite precipitation was shown to be feasible in complex matrices as agro-industrial effluents, characterized by high NH<inf>4</inf><sup>+</sup>, alkalinity, solids and organic content, and interfering ions such as Ca<sup>2+</sup> and K<sup>+</sup>.

Stabilization of fine fraction from landfill mining in anaerobic and aerobic laboratory leach bed reactors

Fine fraction (FF, <20mm) from mined landfill was stabilized in four laboratory-scale leach bed reactors (LBR) over 180days. The aim was to study feasibility of biotechnological methods to treat FF and if further stabilization of FF is possible. Four different stabilization methods were compared and their effects upon quality of FF were evaluated. Also during the stabilization experiment, leachate quality as well as gas composition and quantity were analyzed. The methods studied included three anaerobic LBRs (one without water addition, one with water addition, and one with leachate recirculation) and one aerobic LBR (with water addition). During the experiment, the most methane was produced in anaerobic LBR without water addition (18.0LCH<inf>4</inf>/kgVS), while water addition and leachate recirculation depressed methane production slightly, to 16.1 and 16.4LCH<inf>4</inf>/kgVS, respectively. Organic matter was also removed via the leachate and was measured as chemical oxygen demand (COD). Calculated removal of organic matter in gas and leachate was highest in LBR with water addition (59gCOD/kgVS), compared with LBR without water addition or with leachate recirculation (51gCOD/kgVS). Concentrations of COD, ammonium nitrogen and anions in leachate decreased during the experiment, indicating washout mechanism caused by water additions. Aeration increased sulfate and nitrate concentrations in leachate due to oxidized sulfide and ammonium. Molecular weight distributions of leachates showed that all the size categories decreased, especially low molecular weight compounds, which were reduced the most. Aerobic stabilization resulted in the lowest final VS/TS (13.1%), lowest respiration activity (0.9-1.2mgO<inf>2</inf>/gTS), and lowest methane production after treatment (0.0-0.8LCH<inf>4</inf>/kgVS), with 29% of VS being removed from FF. Anaerobic stabilization methods also reduced organic matter by 9-20% compared with the initial amount. Stabilization reduced the quantity of soluble nitrogen in FF and did not alter concentration of soluble and insoluble phosphorus, and insoluble nitrogen. All four stabilization methods decreased organic matter and thus are possible stabilization methods for FF, but aerobic treatment was the most efficient in this study.

Spatial variations in bacterial and archaeal abundance and community composition in boreal forest pine mycorrhizospheres

Mycorrhizal fungi have a strong impact on soil biota. In this study, bacterial and archaeal populations in different parts of Suillus bovinus - Pinus sylvestris mycorrhizospheres in boreal forest were quantified and identified by DNA analysis. The numbers of bacterial and archaeal 16S rRNA gene copies were highest in uncolonized humus and lowest in fruiting bodies. The numbers of bacterial 16S rRNA gene copies varied from 1.3 × 107 to 3.1 × 109 copies g−1 fw and archaeal copies from 4.1 × 107 to 9.6 × 108 copies g−1 fw. The relatively high number of archaeal 16S rRNA gene copies was likely due to the cold and highly organic habitat. The presence of hyphae appeared to further promote archaeal numbers and the archaea:bacteria ratio was over one in samples containing only fungal material. Most detected archaea belonged to terrestrial Thaumarchaeota. Proteobacteria, Actinobacteria and Acidobacteria were predictably the dominating bacterial taxa in the samples with clear trend of Betaproteobacteria preferring the pine root habitats.

Sorption of zinc onto elemental selenium nanoparticles immobilized in Phanerochaete chrysosporium pellets

The use of a novel hybrid biosorbent, elemental selenium nanoparticles (nSe0) immobilized in pellets of Phanerochaete chrysosporium, to remove Zn from aqueous solutions was investigated. Fungal pellets containing nSe0 (nSe0-pellets) showed to be better biosorbents as they removed more Zn (88.1 ± 5.3 %) compared to Se-free fungal pellets (56.2 ± 2.8 %) at pH 4.5 and an initial Zn concentration of 10 mg L−1. The enhanced sorption capacity of nSe0-pellets was attributed to a higher concentration of sorption sites resulting in a more negative surface charge density, as determined by analysis of the potentiometric titration data. Fourier transform infrared spectroscopy (FT-IR) analysis of fungal pellets prior to and after being loaded with Zn showed the functional groups, including hydroxyl and carboxyl groups, involved in the sorption process. The experimental data indicated that the sorption rate of the nSe0-pellets fitted well to the pseudo-second order kinetic model (R2 = 0.99), and the sorption isotherm was best represented by the Sips model (Langmuir-Freundlich) with heterogeneous factor n = 1 (R2 = 0.99), which is equivalent to the Langmuir model. Operational advantages of fungal pelleted reactors and the Zn removal efficiencies achieved by nSe0-pellets under mild acidic conditions make nSe0-pellet based bioreactors an efficient biosorption process.

Social Norms in Water Services: Exploring the Fair Price of Water

The aim of this article is to analyse price fairness in water services. Although a considerable amount of literature has been published on water pricing, these studies have mainly approached the question from instrumental and rational perspectives. Little attention has been paid to the human side of water pricing. Therefore, the general objective of this research is to shed light on these softer factors, filling the gap in knowledge of the emotional connections with water services. In this research, we explored people’s ideas and views about water pricing by conducting 74 interviews in 11 municipalities in Finland. The results suggest that people are not just rational consumers of a good but also have emotional ties to water utilities and municipal decision-making. The general attitude towards a water utility is confident and sympathetic if its operations and municipal decision-making processes are considered as fair, and vice versa. This is a topical issue as many water utilities are facing pressures to increase water prices; being fair appeared to be crucial way to gain appreciation and support through difficult times. Because fairness seems to be an emergent property of social experiences, special attention should be paid to the “soft side” of water services.

Simultaneous nutrient removal and lipid production with Chlorella vulgaris on sterilized and non-sterilized anaerobically pretreated piggery wastewater

Piggery wastewater is a potent nutrient source for microalgal lipid production. Wastewater has been usually sterilized when used for microalgal cultivation. This is uneconomical in large-scale applications. Therefore, lipid productivity of Chlorella vulgaris CY5 using sterilized and non-sterilized diluted anaerobically pretreated piggery wastewater was studied in batch reactors. The maximum average lipid productivity was obtained after 12 days of incubation and it was higher with the sterilized wastewater than with the non-sterilized one (117g/L/d vs. 91.3g/L/d), due to the higher biomass concentration. Because of the unexpected increase of dissolved organic carbon (DOC) in the cultures, second experiment was conducted to characterize the composition of produced DOC in non-sterilized wastewater. Carbohydrate content increased in the liquid phase but decreased in the biomass after nitrogen had been exhausted. After 12 days of incubation, soluble chemical oxygen demand (COD<inf>s</inf>) was 414±56mg/L, biomass production was 2.8±0.15g/L, and lipid content was 30.3±1.2wt%. Average lipid productivity from day zero to day 12 was 70.5±1.1g/L/d. C. vulgaris removed nutrients from the non-sterilized wastewater and produced oleaginous biomass, although the lipid productivity was higher with sterilized wastewater.

Short Global History of Fountains

Water fountains are part of every human settlement, and historical and mythological stories. They are the source from which life-sustaining water was distributed to people until piped systems started providing fresh tap water inside buildings. In many places, people visit fountains to experience the freshness of running water, to prepare for prayers, or to make a wish. Fountains have also provided water for the people of cities under siege, and purified believers as part of holy rites. The Castalia shrine in Delphi, Greece, for its part, is a spot where various groups of people come to socialize, which greatly improves the quality of their lives. This paper is a look back through the history of fountains in various parts of the world. Experts from various areas have identified the historic, cultural, and ritualistic aspects of fountains and their findings are summarized. The paper concludes by providing a glimpse into the role of fountains in modern society and their continued influence in our lives today.

Service Failures of Rural Water Supply Systems in Ethiopia and Their Policy Implications

As the world is striving to improve water supply coverage, a significant number of rural communities are forced to turn back to unprotected sources due to service breakdowns of their water supply systems. Yet, these communities do not seem to receive the same attention as those building new systems. The purpose of this article is to reveal and diagnose the determinant factors of service failures and to propose mitigation measures to the rural water supply in Ethiopia. The study is conducted through a literature review and field discussions with experts (n = 48) and artisans (n = 35), who have been involved in the implementation, operation, and maintenance of the systems. Moreover, failed schemes (n = 20) were visited, and discussions were held with village elders of each water point. The findings indicate that lack of uniformity of implementation approaches, and institutional and organizational incapability of the local government aggravate the service failures. The further capacity building, institutionalization, and improving remuneration of employees are likely to reduce the problems substantially.

Selecting an indigenous microalgal strain for lipid production in anaerobically treated piggery wastewater

The aim of this study was to select a potential microalgal strain for lipid production and to examine the suitability of anaerobically treated piggery wastewater as a nutrient source for production of lipid-rich biomass with the selected microalga. Biomass and lipid productivity of three microalgal strains (Chlorella sorokiniana CY1, Chlorella vulgaris CY5 and Chlamydomonas sp. JSC-04) were compared by using different media, nitrogen sources, and nitrogen concentrations. The highest lipid content and productivity (62.5 wt%, 162 mg/L/d) were obtained with C. vulgaris with BG-11 with 62 mg N/L. Secondly, C. vulgaris was cultivated in sterilized, diluted (1–20×), anaerobically treated piggery wastewater. Biomass production decreased and lipid content increased, when wastewater was more diluted. The highest lipid content of 54.7 wt% was obtained with 20× dilution, while the highest lipid productivity of 100.7 mg/L/d with 5× dilution. Piggery wastewater is a promising resource for mass production of oleaginous microalgal biomass.

Screening biological methods for laboratory scale stabilization of fine fraction from landfill mining

Abstract Increasing interest for the landfill mining and the amount of fine fraction (FF) in landfills (40–70% (w/w) of landfill content) mean that sustainable treatment and utilization methods for FF are needed. For this study FF (<20 mm) was mined from a municipal solid waste (MSW) landfill operated from 1967 to 1989. FF, which resembles soil, was stabilized in laboratory scale reactors in two phases: first, anaerobically for 101 days and second, for 72 days using four different methods: anaerobic with the addition of moisture (water) or inoculum (sewage sludge) and aerobic with continuous water washing, with, or without, bulking material. The aim was to evaluate the effect on the stability of mined FF, which has been rarely reported, and to study the quality and quantity of gas and leachate produced during the stabilization experiment. The study showed that aerobic treatment reduced respiration activity (final values 0.9–1.1 mg O2/g TS) and residual methane potential (1.1 L CH4/kg TS) better than anaerobic methods (1.8–2.3 mg O2/g TS and 1.3–2.4 L CH4/kg TS, respectively). Bulking material mixed in FF in one aerobic reactor had no effect on the stability of FF. The benefit of anaerobic treatment was the production of methane, which could be utilized as energy. Even though the inoculum addition increased methane production from FF about 30%, but the methane production was still relatively low (in total 1.5–1.7 L CH4/kg TS). Continuous water washing was essential to remove leachable organic matter and soluble nutrients from FF, while increasing the volume of leachate collected. In the aerobic treatment, nitrogen was oxidized into nitrite and nitrate and then washed out in the leachate. Both anaerobic and aerobic methods could be used for FF stabilization. The use of FF, in landscaping for example, is possible because its nutrient content (4 g N/kg TS and 1 g P/kg TS) can increase the nutrient content of soil, but this may have limitations due to the possible presence of heavy metal and other contaminants.

Scaling up the treatment of the fine fraction from landfill mining: Mass balance and cost structure

The treatment of the fine fraction (FF) obtained from landfill mining is necessary in order to reduce the amount of organic matter and biological activity in FF, thus increasing its potential to be utilized after landfill mining. This paper suggests the scaled up anaerobic and aerobic treatment of FF, with or without continuous irrigation, and presents the mass balance and cost structure of such treatment based on two hypothetical landfills. The physical treatment structure for the treatment of FF should prevent emissions, and in this paper, it includes suitable bottom and top liners as well as the collection and treatment of the gaseous and leachate emissions formed during the treatment. Methane produced in anaerobic treatments could either be utilized for energy recovery or be flared. The cost of the anaerobic and aerobic treatment of FF, including investments and operation costs, are 20–65 €/t FF, depending on size of the landfill. The costs of anaerobic treatment and passive aeration are similar, and active aeration is slightly more expensive, but the cost of the continuous irrigation is the most significant, as it multiplies the leachate treatment costs. The overall cost of treatment could be lowered by reducing the treatment time and utilizing existing landfill structures. The results of this paper can be used in planning and estimating the cost of the biological treatment of FF when evaluating landfill mining projects, as the fate of FF may have a major impact on the economics of landfill mining projects.

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.

Rewiring the wax ester production pathway of acinetobacter baylyi ADP1

Wax esters are industrially relevant high-value molecules. For sustainable production of wax esters, bacterial cell factories are suggested to replace the chemical processes exploiting expensive starting materials. However, it is well recognized that new sophisticated solutions employing synthetic biology toolbox are required to improve and tune the cellular production platform to meet the product requirements. For example, saturated wax esters with alkanol chain lengths C12 or C14 that are convenient for industrial uses are rare among bacteria. Acinetobacter baylyi ADP1, a natural producer of wax esters, is a convenient model organism for studying the potentiality and modifiability of wax esters in a natural host by means of synthetic biology. In order to establish a controllable production platform exploiting well-characterized biocomponents, and to modify the wax ester synthesis pathway of A. baylyi ADP1 in terms product quality, a fatty acid reductase complex LuxCDE with an inducible arabinose promoter was employed to replace the natural fatty acyl-CoA reductase acr1 in ADP1. The engineered strain was able to produce wax esters by the introduced synthetic pathway. Moreover, the fatty alkanol chain length profile of wax esters was found to shift toward shorter and more saturated carbon chains, C16:0 accounting for most of the alkanols. The study demonstrates the potentiality of recircuiting a biosynthesis pathway in a natural producer, enabling a regulated production of a customized bioproduct. Furthermore, the LuxCDE complex can be potentially used as a well-characterized biopart in a variety of synthetic biology applications involving the production of long-chain hydrocarbons. © 2014 American Chemical Society.

Revisiting the feasibility of biomass-fueled CHP in future energy systems – Case study of the Åland Islands

Biomass has been widely recognized as a sustainable fuel for balancing energy systems with high amounts of varying renewable energy production, mainly from wind or solar power. Combined heat and power (CHP) is an efficient technology for biomass utilization and energy system balancing. Currently, the increasing amount of renewable power production often reduces the price of electricity, which makes CHP plants uneconomical. However, this might not be the case in the future, when the subsidies for developing renewable energy sources are reduced or removed. This paper presents a feasibility analysis of the potential for operational flexibility in a bio-fueled CHP plant in a real-life environment using a spreadsheet model. Three different renewable power production schemes for the Åland Islands were analyzed: the present system, a balanced scenario and a high-wind scenario. The analysis was conducted for three different-sized CHP plants run in modes which followed either the heat or the power load. Moreover, in one case two more parameters affecting the magnitude and rate of the flexibility were thoroughly examined: the start-up time and the minimum plant load. The results showed that biomass does have a place in future energy systems, and the spreadsheet tool can effectively be used for a CHP feasibility assessment in different operational environments; both for existing CHP plants and for planning new investments. The results indicate that the availability of inexpensive fuel and sufficient income from heat sales have to be secured as the operational environment of the CHP plant changes. The examination of the operational mode revealed that in the power-following mode, where the CHP plant can offer flexibility services, the plant’s profitability depends on the rate of compensation for the excess heat or spinning hours.

Revisiting cellulase production and redefining current strategies based on major challenges Article reference: RSER5103

Lignocellulosic biomass has been considered as an important and sustainable source of renewable energy. Cellulose constitutes the major component of the lignocellulosic biomass and also offers maximum recalcitrance towards its fullest utilization. The enzymatic breakdown of cellulose is achieved through cellulases. Diverse forms of microbes including fungi, bacteria, actinomycetes and yeast are known to produce cellulases that have found extensive application in various industries. Due to the current global political unrest over oil prices and the threat of global warming following combustion of fossil fuels, the paradigm of research is now focused on biofuel production from plant biomass. Conventional approaches have not been economically feasible for meeting the demands of the industry. This review provides an update regarding the status of present microbial cellulase production technologies and research with special reference to solid state fermentation and different molecular techniques such as mutagenesis, metabolic engineering and heterologous gene expression of cellulases from different microbial domains with improved catalytic and stability properties. Metagenomic and genomic studies for mining of novel cellulase genes in addition to screening of culturable strains using conventional methods have been advanced. In addition the bottlenecks associated with cellulase production and how the future research needs to be directed to provide a comprehensive technology for the production of cellulases with novel traits for application at an industrial level without economic constraints are discussed.

Resilient Asset Management and Governance Fordeteriorating Water Services Infrastructure

This paper argues that strategic asset management and a sound regulatory regime are required urgently if we want to change the current paradigm of aging and decaying water services infrastructure and expand the coverage of improved water services in the developing economies. In the OECD countries access to safe water supply and sanitation has largely been ensured through substantial investment over many decades. Yet, significant investments will still be required to rehabilitate the existing infrastructures, to bring them into conformity with more stringent environmental and health regulations, and to maintain service quality in the future. In the non-OECD countries the challenges are more daunting. Large parts of their population have no access and many suffer from unsatisfactory services. Nearly one billion people lack access to clean drinking water and 2.6 billion people lack access to improved sanitation services.Lack of sound economic regulatory frameworks and enforcement regimes, and poor asset management practices, in particular underpricing of water services is a common problem throughout the world.

Replacing centralised waste and sanitation infrastructure with local treatment and nutrient recycling: Expert opinions in the context of urban planning

Solutions for resource scarcity should be sought from urban waste management and sanitation, which are characterised by central plants and long networks. The socio-technical transition to more sustainable infrastructure is expected to include partial decentralisation based on local conditions. This paper focuses on drivers, barriers and enablers in implementing a decentralised circular system in a new residential area (Tampere, Finland). In the alternative system, biowaste and feces are treated in a local biogas plant, and nutrient and energy output are utilised within the area. This research aims to understand what kind of urban planning enables alternative infrastructure, as well as the characteristics of an innovation capable of making a breakthrough. Seventeen infrastructure planning experts were interviewed, then assembled to re-develop ideas arising from the interviews. Based on these qualitatively analysed data, 11 factors which help the adoption of the alternative system were formulated. The results indicate that sustainability transition can be facilitated through impartial urban planning that allows the early participation of actors and improved communications. Additionally, studying the impact of alternative solutions and city guidance according to environmental policy aims may enhance transition. Innovation success factors include suitable locations, competent partners, mature technology and visible local benefits.

Recycling potential of post-consumer plastic packaging waste in Finland

Recycling of plastics is urged by the need for closing material loops to maintain our natural resources when striving towards circular economy, but also by the concern raced by observations of plastic scrap in oceans and lakes. Packaging industry is the sector using the largest share of plastics, hence packaging dominates in the plastic waste flow. The aim of this paper was to sum up the recycling potential of post-consumer plastic packaging waste in Finland. This potential was evaluated based on the quantity, composition and mechanical quality of the plastic packaging waste generated by consumers and collected as a source-separated fraction, within the mixed municipal solid waste (MSW) or within energy waste.

Based on the assessment 86,000–117,000 tons (18 kg/person/a) of post-consumer plastic packaging waste was generated in Finland in 2014. The majority, 84% of the waste was in the mixed MSW flow in 2014. Due to the launching of new sorting facilities and separate collections for post-consumer plastic packaging in 2016, almost 40% of the post-consumer plastic packaging could become available for recycling. However, a 50% recycling rate for post-consumer plastic packaging (other than PET bottles) would be needed to increase the overall MSW recycling rate from the current 41% by around two percentage points.

The share of monotype plastics in the overall MSW plastics fraction was 80%, hence by volume the recycling potential of MSW plastics is high. Polypropylene (PP) and low density polyethylene (LDPE) were the most common plastic types present in mixed MSW, followed by polyethylene terephthalate (PET), polystyrene (PS) and high density polyethylene (HDPE). If all the Finnish plastic packaging waste collected through the three collection types would be available for recycling, then 19,000–25,000 tons of recycled PP and 6000–8000 tons of recycled HDPE would be available on the local market. However, this assessment includes uncertainties due to performing the composition study only on mixed MSW plastic fraction. In order to obtain more precise figures of the recycling potential of post-consumer plastic packaging, more studies should be performed on both the quantities and the qualities of plastic wastes.

The mechanical and rheological test results indicated that even plastic wastes originating from the mixed MSW, can be useful raw materials. Recycled HDPE showed a smaller decline in the mechanical properties than recycled PP. The origin and processing method of waste plastic seemed to have less effect on the mechanical quality than the type of plastic. The applicability of a plastic waste for a product needs to be assessed case by case, due to product specific quality requirements. In addition to mechanical properties, the chemical composition of plastic wastes is of major importance, in order to be able to restrict hazardous substances from being circulated undesirably.

In addition to quantity and quality of plastic wastes, the sustainability of the whole recycling chain needs to be assessed prior to launching operations so that the chain can be optimized to generate both environmental and economic benefits to society and operators.

Recycling mine tailings in chemically bonded ceramics - A review

Mine tailings account for most of the environmental incidents related to the extractive industry, with risks increasing due to steadily rising tonnage of low-grade ore and extreme weather events. Recycling of tailings in raw-material-intensive applications presents an interesting alternative to costly tailings management with associated restoration efforts. Chemically bonded ceramics may offer a route to upgrading mine tailings into raw materials for ceramics. In this review such chemically bonded ceramic methods that may be used to recycle mine tailings as raw materials, are reviewed while focusing in particular on two methods: 1) geopolymerization/alkali activation and 2) chemically bonded phosphate ceramics. The aim of the review is not to give exhaustive review on the wide topic, but to scope the required boundary conditions that need to be met for such utilization. According to the findings, alkali activation has been studied for 28 separate silicate minerals in the scientific literature, and presents a viable method, which is already in commercial use in calcium-rich cement-like binder applications. Phosphate bonding literature is more focused on phosphate containing minerals and waste encapsulation. Very little work has been done on low-calcium tailings utilization with either technology, and more knowledge is needed on the effect of different pre-treatment methods to increase reactivity of mine tailings in chemically bonded ceramics.

Recent advances in nutrient removal and recovery in biological and bioelectrochemical systems

Nitrogen and phosphorous are key pollutants in wastewater to be removed and recovered for sustainable development. Traditionally, nitrogen removal is practiced through energy intensive biological nitrification and denitrification entailing a major cost in wastewater treatment. Recent innovations in nitrogen removal aim at reducing energy requirements and recovering ammonium nitrogen. Bioelectrochemical systems (BES) are promising for recovering ammonium nitrogen from nitrogen rich waste streams (urine, digester liquor, swine liquor, and landfill leachate) profitably. Phosphorus is removed from the wastewater in the form of polyphosphate granules by polyphosphate accumulating organisms. Alternatively, phosphorous is removed/recovered as Fe-P or struvite through chemical precipitation (iron or magnesium dosing). In this article, recent advances in nutrients removal from wastewater coupled to recovery are presented by applying a waste biorefinery concept. Potential capabilities of BES in recovering nitrogen and phosphorous are reviewed to spur future investigations towards development of nutrient recovery biotechnologies.

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.

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.

Radon, fungal spores and MVOCs reduction in crawl space house: A case study and crawl space development by hygrothermal modelling

In this case study was to investigate how ventilation of the crawl space will influence on concentrations of radon, fungal spores and MVOCs in the crawl space and indoors of detached house. The crawl space pressurisation by exhaust air from indoors was successful to prevent the convective flow of radon from the soil, but it increased microbial growth in the crawl space. After installation of the supply and exhaust ventilation in the crawl-space and in the living space, the concentrations of fungal spores in the crawl space and also entry of radon and MVOCs into a house decreased. A microbiologically safe crawl space was determined with hygrothermal simulation utilizing the Finnish Mould Growth Model and a two year examination period. The optional structures of the crawl space being depressurised with exhaust ventilation included an open base uncovered ground and various air-sealed closed structures. When mould growth of building materials was at medium resistant sensitivity class, mould was not observed during different air change rates in any of the examined structures. Open base uncovered gravel ground is a functional solution of a crawl space, only when there are no organic materials. The air-sealed ground structure is recommended build with concrete + insulation and when air exchange rate (ach) varied from 0.2 to 1 h−1. A concrete ground in the crawl space having ach from 0.2 to 0.6 h−1 is also very effective. XPS insulation and plastic sheet covered ground are not recommendable due to their high mould index.

Pt-functionalized Fe2O3 photoanodes for solar water splitting: the role of hematite nano-organization and the platinum redox state

Pt/alpha-Fe2O3 nanocomposites were synthesized on fluorine-doped tin oxide (FTO) substrates by a sequential plasma enhanced-chemical vapor deposition (PE-CVD)/radio frequency (RF) sputtering approach, tailoring the overall Pt content as a function of sputtering time. The chemico-physical properties of the as-prepared systems were extensively investigated by means of complementary techniques, including X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), field emission-scanning electron microscopy (FE-SEM), energy dispersive X-ray spectroscopy (EDXS), secondary ion mass spectrometry (SIMS), and optical absorption spectroscopy, and compared to those of the homologous Pt/alpha-Fe2O3 systems annealed in air prior and/or after sputtering. The obtained results evidenced that the material compositional, structural and morphological features, with particular regard to the Pt oxidation state and hematite nano-organization, could be finely tailored as a function of the adopted processing conditions. Pt/alpha-Fe2O3 systems were finally tested as photoanodes in photoelectrochemical (PEC) water splitting experiments, evidencing a remarkable interplay between functional performances and the above-mentioned material properties, as also testified by transient absorption spectroscopy (TAS) results.

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.

Preferential adsorption of Cu in a multi-metal mixture onto biogenic elemental selenium nanoparticles

Preferential adsorption of Cu contained in wastewaters is desirable as the Cu can then be reprocessed and reused more easily. In this study, biogenic elemental selenium nanoparticles (BioSeNPs) were assessed for their ability to preferentially adsorb Cu from an equimolar mixture containing Cu, Cd and Zn. Variations in metal to BioSeNPs ratios and initial metal solution pH improved the preferential adsorption capacity of BioSeNPs toward Cu, with the ratio of Cu adsorbed to combined Cd and Zn adsorbed varying from 2.3 to 6.6. More than 78% of the added Cu was adsorbed at an initial metal solution pH of 5.2 and metal to BioSeNPs ratio of 0.21mgmg-1 when the ratio of Cu adsorbed to the sum of Cd and Zn adsorbed was 2.3. Infrared spectroscopy revealed that the Cu, Cd and Zn were interacting with the hydroxyl and carboxyl surface functional groups of the BioSeNPs. The modeling of BioSeNPs' acid-base titration revealed the presence of high concentrations of carboxylic groups (C=60.3molkg-1) with a pKa of 3.9, providing further evidence of their interaction with Cu. The adsorption of Cu resulted in a lower colloidal stability of the BioSeNPs as indicated by more than 99% retention of added BioSeNPs after adsorption of heavy metals and filtration. BioSeNPs showed a good preferential adsorption capacity toward Cu as compared to other adsorbent. This study provides a proof-of-concept for the preferential adsorption of Cu onto BioSeNPs which are present in the effluent of a bioreactor treating selenium oxyanions containing wastewater.

Power generation in fed-batch and continuous up-flow microbial fuel cell from synthetic wastewater

Up-flow bioreactors have the advantages of retaining very high cell density and having high mass transfer efficiency. The recirculation rate could improve the up-flow rate in up-flow bioreactor. A two-chamber UFMFC (up-flow microbial fuel cell) is constructed with flat graphite electrodes and anion exchange membrane for electricity generation. The anode chamber is seeded with compost culture enriched on xylose and operated on synthetic wastewater with 0.5 g/L xylose, external resistance of 100 Ω, at pH 7.0 and 37 °C in fed-batch mode. The cathode chamber in the top of the UFMFC is filled with potassium ferricyanide (pH 7.0) as the electron acceptor. The effects of different recirculation rates of 1.2, 2.4, 4.8 and 7.2 RV (reactor-volumes)/h to increase the mass transfer and electricity production are determined in fed-batch mode. At a recirculation rate of 4.8 RV/h, a power density of 356 ± 24 mW/m2 with CE (coulombic efficiency) of 21.3 ± 1.0% is obtained. Decreasing HRT (hydraulic retention time) could improve the electricity production performance of UFMFC in continuous mode. The power generation is increased to 372 ± 20 mW/m2, while CE remains at 13.4 ± 0.5% with HRT of 1.7 d and optimum recirculation rate of 4.8 RV/h on continuous mode. Microbial communities were characterized with PCR (polymerase chain reaction) - DGGE (denaturing gradient gel electrophoresis). In the end of the experiment, the biofilm contained both fermenting and exoelectrogenic bacteria, while fermenting and nitrate-reducing bacteria were mainly present in the anodic solutions. Moreover, some changes occurred in the microbial communities of the anodic solutions when the MFCs were switched from fed-batch to continuous mode, while the differences were minor between different recirculation rates in fed-batch mode.

Plasma-Assisted Fabrication of Fe2O3 - Co3O4 Nanomaterials as Anodes for Photoelectrochemical Water Splitting

Nanocomposite Fe2O3?Co3O4 photoanodes for photoelectrochemical H2O splitting were prepared by a plasma-assisted route. Specifically, Fe2O3 nanostructures were grown by plasma enhanced-chemical vapor deposition, followed by cobalt sputtering for different process durations. The systems were annealed in air after, or both prior and after, sputtering of Co, to analyze the treatment influence on functional performances. The interplay between processing conditions and chemico-physical features was investigated by a multi-technique characterization. Photocurrent density measurements in sunlight-assisted H2O splitting revealed a performance improvement upon Co3O4 loading. A cathodic shift of the onset potential was also observed, highlighting Co3O4 activity as catalyst for the oxygen evolution reaction.

Planning land use for biogas energy crop production: The potential of cutaway peat production lands

Each year, thousands of hectares of peatland that had been harvested are being released in Finland, which can offer an opportunity to increase energy crops and attain the bioenergy targets for non-agriculture lands. In this study, the Geographic Information System (GIS) method was used to improve the assessment of decentralized renewable energy resources. The amount of peat production lands and future cutaway areas for energy crop production was calculated as a case study by using ArcGIS and the Finnish Topographic database. There are almost 1000 km2 of peat production lands in Finland, and theoretically, approximately 300 km2 of cutaway peatlands could be used for energy crops after 30 years. The dry biomass yield of reed canary grass (Phalaris arundinacea) or timothy-fescue grass (mix of Phleum pratense and Festuca pratensis) could be higher than 100 Gg a-1 in these lands indicating methane potential of approximately 300 GWh. The exhausted peat production areas in the western region of Finland have significant potential for use for energy crops; North and South Ostrobothnia account for almost 45% of the total peat production land. A future goal could be to use the cutaway peat production lands more efficiently for bioenergy to mitigate climate change. Since the use of wastelands (including peatlands) are being considered in Europe as a way to avoid competition with food production, the GIS method used in the study to identify suitable peat lands could be applicable to biomass resource studies being conducted in many countries.

Particulate Mass and Nonvolatile Particle Number Emissions from Marine Engines Using Low-Sulfur Fuels, Natural Gas, or Scrubbers

In order to meet stringent fuel sulfur limits, ships are increasingly utilizing new fuels or, alternatively, scrubbers to reduce sulfur emissions from the combustion of sulfur-rich heavy fuel oil. The effects of these methods on particle emissions are important, because particle emissions from shipping traffic are known to have both climatic and health effects. In this study, the effects of lower sulfur level liquid fuels, natural gas (NG), and exhaust scrubbers on particulate mass (PM) and nonvolatile particle number (PN greater than 23 nm) emissions were studied by measurements in laboratory tests and in use. The fuel change to lower sulfur level fuels or to NG and the use of scrubbers significantly decreased the PM emissions. However, this was not directly linked with nonvolatile PN emission reduction, which should be taken into consideration when discussing the health effects of emitted particles. The lowest PM and PN emissions were measured when utilizing NG as fuel, indicating that the use of NG could be one way to comply with up-coming regulations for inland waterway vessels. Low PN levels were associated with low elemental carbon. However, a simultaneously observed methane slip should be taken into consideration when evaluating the climatic impacts of NG-fueled engines.

Particle growth with photochemical age from new particle formation to haze in the winter of Beijing, China

Secondary aerosol formation in the aging process of primary emission is the main reason for haze pollution in eastern China. Pollution evolution with photochemical age was studied for the first time at a comprehensive field observation station during winter in Beijing. The photochemical age was used as an estimate of the timescale attributed to the aging process and was estimated from the ratio of toluene to benzene in this study. A low photochemical age indicates a fresh emission. The photochemical age of air masses during new particle formation (NPF) days was lower than that on haze days. In general, the strongest NPF events, along with a peak of the formation rate of 1.5 nm (J1.5) and 3 nm particles (J3), were observed when the photochemical age was between 12 and 24 h while rarely took place with photochemical ages less than 12 h. When photochemical age was larger than 48 h, haze occurred and NPF was suppressed. The sources and sinks of nanoparticles had distinct relation with the photochemical age. Our results show that the condensation sink (CS) showed a valley with photochemical ages ranging from 12 to 24 h, while H2SO4 concentration showed no obvious trend with the photochemical age. The high concentrations of precursor vapours within an air mass lead to persistent nucleation with photochemical age ranging from 12 to 48 h in winter. Coincidently, the fast increase of PM2.5 mass was also observed during this range of photochemical age. Noteworthy, CS increased with the photochemical age on NPF days only, which is the likely reason for the observation that the PM2.5 mass increased faster with photochemical age on NPF days compared with other days. The evolution of particles with the photochemical age provides new insights into understanding how particles originating from NPF transform to haze pollution.

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.

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.

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.

Numerical modeling of fine particle and deposit formation in a recovery boiler

In kraft pulp mills, black liquor is concentrated and burned in recovery boilers to produce steam and power and to recover pulping chemicals. Black liquor contains a large amount of alkali compounds, which form ash with low melting temperatures upon combustion. This causes many problems in recovery boiler operation, including fouling of the heat transfer surfaces, plugging of the flue gas passages, reduction of the heat transfer rate, and corrosion of the superheater tubes. This paper presents a model for simulating fine fume particles formed as a result of condensation of alkali compound vapors in the recovery boiler. The modeling method combines CFD modeling, equilibrium chemistry, and fine particle dynamics in a way that enables simulation of a full scale three-dimensional boiler environment. The model has been partially validated with measurements performed in an operating recovery boiler. The modeling results, particularly for the fume particle composition, agree well with the actual measurements. (C) 2014 Elsevier Ltd. All rights reserved.

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.

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.

Municipal challenges in managing a building with noted health symptoms

Purpose

This study aims to present property management challenges that municipalities have encountered regarding a public building with noted building-related symptoms. The study goes on to provide reasons for the failure of attempts to manage the symptoms and discusses the current challenges concerning the process.

Design/methodology/approach

A participatory case study was used as the research methodology to identify the current challenges concerning a municipal approach to managing the building-related symptoms in a case-study building. The researchers scrutinised the history of the health symptom management process and attended the project planning meetings focused on the investigation of the condition of the building.

Findings

Multiple challenges concerning maintenance and omitted or postponed repair actions, as well as vagueness in the management process were found. In addition to this, it was noted that the complexity of the initial design of the building and vandalism have resulted in challenges for the maintenance and moisture performance of the building structures. According to the study, more orderliness and a more systematic process is needed when managing a municipal property.

Practical implications

The identified property management challenges may be of practical value for the facility managers and the property owners, especially when managing the building-related symptoms and a damaged building.

Originality/value

This study highlights the importance of having an in-depth understanding of condition assessments as well as proper maintenance and timely repairs for the successful management of the building-related symptoms in a municipal building. This is a pilot project in a larger project of management of building refurbishment.

Modelling of plastic culvert and road embankment interaction in 3D

A series of 3D Finite Element simulations was performed to investigate the effect of different factors influencing the distortions undergone by a plastic culvert tube while subject to external loading from a heavy truck. The applied simulation model was verified by full-scale loading tests carried out on a number of actual culvert installation sites. Based on the results of the study, it can be concluded that both installation depth and quality of the material surrounding the culvert have a dominant effect on culvert distortions while the effects of material quality above the culvert and the type of tyre configuration transmitting the wheel load are much less pronounced.
