PRODUCTION OF BIOGAS FROM SOLID ORGANIC WASTES THROUGH ANAEROBIC DIGESTION

Abstract

Anaerobic digestion treatments have often been used for biological stabilization of solid wastes. These treatment processes generate biogas which can be used as a renewable energy sources. Recently, anaerobic digestion of solid wastes has attracted more interest because of current environmental problems, most especially those concerned with global warming. Thus, laboratory-scale research on this area has increased significantly. In this study, the production of biogas from solid wastes according to its origin via various anaerobic technologies was presented. Food, agriculture, garbage and chicken manure were investigated for producing biogas production under mesophlilc conditions. Animal manure was added as a starter to facilitate the anaerobic digestion process. The obtained results show that, the biogas produced ranged between 23.32.to50.11.L/L. The highest biogas yield was observed with chicken manure waste to50.11.L/L compared to other wastes.
