Abstract

This study reports the production of biogas using poultry manure and banana peels as a co-substrate, the experiments were carried out in a 20 litre biodigester and incubated for 50 days at mesophilic temperature of 34oC and pH of 6.8. The results show that the production of biogas began on the 10th day with a yield of 1.90 ml and increased continuously to the 20th day with an optimal yield of 17.30ml. Then, the yield decreased for the remaining period but did not cease till the 50th day. Kinetic models were used to compare biogas production at the ascending limb and the exponential and first order kinetic model had a better correlation and fit.
