Abstract

This paper reports the research work carried out on the study of anaerobic co-digestion of non-uniform multiple feed stock availability and composition in Nigeria. Organic municipal solid wastes comprises of the composition of corn cobs, potato peels, pineapple peels, rice waste, yam peels, cassava peels, orange peels, garri leftover and banana peels, was digested separately and the same time co-digested with wastewater collected from septic tanks, abattoir, and cold room in Benin City, Nigeria. The results obtained shows that the co-digestion of organic municipal solid wastes and wastewater had better average biogas yields (0.625), shorter retention period of 29 days, frequent number of evacuation and average rate of biogas yield of 0.0217 when compared to anaerobic digestion of organic municipal solid wastes only with an average biogas yield of 0.4025, longer retention period of 38 days and average rate of biogas yield of 0.0106. Therefore, anaerobic co-digestion of organic municipal solid wastes and wastewater enhances better biogas yields.
