Abstract

Biogas production from anaerobic co-digestion of cow dung (CD), chicken manure (CM), pig manure (PM) sewage waste (SW) was evaluated in laboratory batch scale at ratios 1:1:1:1, 2:1:1:1 and 3:1:1:1. Highest methane yields were achieved from CD to CM, PM and SW at ratio of 1:1:1:1 (58% CH4/d). The effect of temperature on methane yield was also investigated at 35, 40, 50 and 55 f degrees C. The optimum temperature for anaerobic co-digestion was found to be 40 degrees C with the highest methane yield of 62% CH4/d on Day 6 of the gas production. Ratios of 3:1:1:1 had the highest impurities followed by ratios of 2:1:1:1 and 1:1:1:1, respectively. The study has shown that co-digestion of animal waste or other organic wastes is more advantageous than processing each feedstock separately.
