INFLUENCE OF INOCULUM PERCENTAGE ON BIOGAS PRODUCTION FROM MUNICIPAL SOLID WASTE USING COW DUNG AS INOCULUM

Anaerobic digestion of municipal solid waste was carried out in this study for 60 days at room temperature in batch reactors with different percentage of cow dung as inoculum. The digestion was carried out in laboratory scale. The characteristics of the MSW and cow dung were analyzed. The daily biogas production from the reactors was measured. At the end of the study, the biogas yield from the reactors R1, R2, R3, and R4 was 24.88 L, 64.45 L, 79.74 L, and 109.18 L respectively. The percentage of methane in the biogas was found to be 70%.
