Abstract

Kinetic investigations of biogas produced from Cow dung and Elephant dung were carried out. Three samples tagged: 1 (100% Cow dung), 2 (50% Cow dung and 50% Elephant dung) and 3 (100% Elephant dung) were investigated in prototype batch bio-digesters using anaerobic digestion process. In addition, the kinetic studies of the three samples investigated were carried out. Results obtained revealed that Sample ‘2’, the co-digestion of Cow and Elephant dung gave the best cumulative biogas production of 3.92*10-4 g/cm3 and average yield of 0.084 5 over a period of 33 days. The kinetic of the process followed a shifting order (0-1); the kinetic parameters obtained can be used to size bio-digester and also monitor the rate of biogas produced. Therefore, the co-digestion of Elephant and Cow dung in equal proportion can be used to increase yield of biogas.
