On the influence of mechanical and chemical input preparation on the efficiency of biogas production from organic beach wastes

Abstract

Beach waste from freshwater sources is a harsh substrate to generate biogas from it. The tests showed that only high-pressure steam explosion pre-treatment can make the material suitable for biogas production on an economic feasible way. The method allows for an increase biogas yield from approximately 50 1/kg,™ to about 300 l/kgoTS using the high-pressure steam explosion technology. The technology allows therefore for almost similar biogas volume as generated from cattle waste or straw. The results strongly support the idea to use beach waste from freshwater as a co-substrate in biogas plantsVytauto Didžiojo universitetasŽemės ūkio akademij
