Hydrolysis and acidification of source sorted household solid waste (SSHSW) at 70°C was studied using continuous stirred tank reactor (CSTR). The soluble COD/total initial COD-ratio of the SSHSW increased from 25 to 35% during the CSTR treatment. A thermophilic (55°C) upflow anaerobic sludge blanket (UASB) reactor removed up to 80% of the COD in the liquid fraction of the SSHSW treated at 70°C.
