Methane production from anaerobic digestion of poultry waste / Hazwani Hasmi

Chicken consumption rate had increased year by year and subsequently producing huge number of poultry waste. Lack management of poultry waste will negatively affect the environment. Anaerobic digestion is one of the technologies that can be used to manage poultry waste while producing renewable energy. In this study, the physical, chemical and biological characteristics of poultry waste, POME and wastewater sludge was examined. To enhance the production of methane gas, the optimum condition during anaerobic digestion of poultry waste was investigated; pH, temperature, ratio of poultry waste and water, ratio of substrate and inoculum, hydraulic retention time, types of inoculum, and nitrogen purging. The anaerobic digestion was performed by using serum bottle and 5 L glassware as Jbioreactors. Methane production was measured daily by GC-FID.
