Synergistic Biogas Production: Optimizing Methane Yields from Egg-Laying Chicken, Broiler Chicken, and Cow Dung Waste Mixtures.

Anaerobic digestion for biogas production was assessed utilizing egg-laying chicken, broiler chicken and cow dung as co-substrate. This was demonstrated in varying reactors named R1, R2, R3, and R4 containing various proportions of egg-laying chicken, broiler chicken and cow dung with a total solid concentration of 8%. This experiment was carried out for 40 days at a temperature of 25ºC. The volatile solid and chemical oxygen demand for all the reactors were as follows; 29.1, 56.6, 44.7, and 36.6% and 54.5, 89.17, 70.1, and 64.01% respectively. R2 contains 75% egg-laying chicken and 25% cow dung gave the optimal outcomes; a methane yield of 85.4%, and VS reduction of 56.6%.
