Production of biogas from food waste in laboratory scale dry anaerobic digester under mesophilic condition

Organic matter specifically food and vegetable waste contains the utmost proportion of the composition of solid waste in Bangladesh. It is estimated that the food waste generation rate of Bangladesh University of Professionals (BUP) from its two major waste generation sources field mess and vista cafeteria is around 130–140 kg/day. There is an increasing concern to reduce this food waste burden by adopting appropriate measures. Therefore, the prime objective of this study was to manage the food waste generated in BUP by producing biogas through laboratory-scale dry anaerobic digestion processes under mesophilic conditions. The proximate analysis of food wastes or feedstock revealed that the solid content of feedstock was more than 15% which is considered suitable for dry anaerobic digestion.…
