N2 - Coffee waste is rich in organic material and is a potential raw material for biogas production. In this study, 5kg of coffee waste was anaerobically digested for 40 days. The changes in the coffee waste chemical oxygen demand (COD), biological oxygen demand (BOD) and total solids (TS) was monitored every 10 days as well as the biogas production. The amount of biogas produced was measured for both mesophilic conditions of 35 C and thermophilic conditions of 55 C. The amount of biogas produced increased with increase in time with a 60% conversion to biogas being achieved for mesophilic conditions. The enhanced biogas production under mesophilic conditions was related to the 88%, 91% and 90% decrease in COD, BOD and TS. The biogas produced had an average methane content of 70%.
