Abstract: In today’s energy demanding life style, there is always a need for exploring and exploiting new sources of energy which are renewable as well as eco-friendly. Sawdust, generated by numerous sawmills situated along rivers, poses a great problem, as it gradually encroaches into the river causing environmental menace to aquatic life. This work proposes the utility of sawdust, co-digested with cow dung and water hyacinth to generate biogas as a means of its reuse and misuse. Varying amounts of sawdust waste complimented with a fixed amount of cow dung and water hyacinth was anaerobically fermented in batch-fed digesters, in the laboratory, at the same operating conditions. Biogas was measured for a period of 64 days at an average ambient temperature of 30oC. The results show that efficient biogas production rate was maximum (0.046litres/TS fed) when about 11.58 g of sawdust waste was digested in a fixed amount of cow dung and water hyacinth (7 g).This corresponds to about 8 to 9.6% total solid content in the anaerobic digester which lies within the recommended percentage range for optimum biogas production.
