The optimum mesophilic temperature of biogas production from blends The optimum temperature of biogas production from blends of animal-based wastes was determined under controlled heat supply to the digester in a batch digestion process. Cow Dung (CD) and Poultry Droppings (PD) were blended in the ratio of CD: PD: 1:3. The digester was operated at average ambient temperature of 30°C as baseline. Biogas production from the waste blends was monitored under the temperatures of 32 to 45°C. Results obtained indicate maximum cumulative gas yield was observed at the temperature of 40°C. The 40°C temperature gave the highest biogas yield of 2685 mL followed by the 35°C temperature with the cumulative yield of 2535 mL. The ambient temperature of 30°C had the least cumulative biogas yield of 185 mL. These results indicate that increased and steady biogas production can be achieved under the optimum mesophilic temperature of 40°C when these animal-based wastes are digested in batch digestion process.
