Optimization of biogas production and quality from chicken droppings by anaerobic co-digestion withCymbopogon citratuswas investigated. The anaerobic digestions of chicken droppings, chicken droppingswithC. citratusas well asC. citratusalone were carried out for a period of 30 days at an average ambienttemperature of 33.1�2�C using identical reactors (AeC) respectively. Results obtained indicate thatchicken droppings produced on the average 1.8 L/kg/day of biogas, co-digestion of chicken droppings andC. citratusproduced 1.3 L/kg/day of biogas whileC. citratusalone produced 1.0 L/kg/day with estimatedaverage methane content of 41.71%, 66.20% and 71.95% for reactors AeC respectively. The water boilingrates of biogas from chicken droppings, chicken droppings withC. citratus, andC. citratusalone were0.079 L/min, 0.091 L/min and 0.12 L/min respectively, after the gases were scrubbed with water andslaked lime. It was observed that notwithstanding the higher biogas volumetric yield from chickendroppings digested alone, the co-digestion of chicken droppings withC. citratushad better gas qualitywith respect to the methane content present and cooking rate. This study has shown that the methanecontent of biogas from animal manure substrates could be improved by co-digestion with energy plants
