Popis: The objective of the present work was to investigate the influence of co-digestion of agricultural waste, food and kitchen waste and municipal solid waste with animal manure for enhanced biogas production. Cow dung has been used for the generation of biogas, but complete depolymerization is not obtained till now. So, it is codigested with other substrates to increase the depolymerization of substrates. So, co-digestion of selected substrates withcow dung has been performed. Results show that co-digestion of cow-dung with lignocellulosic biomass is good for the enhancement of bio-energy production. This has been suggested by a decrease in COD is 42.66%, 28.42%, 41.46%, 52.74%, 65.21% and 21.09% for cow dung slurry, a combination of cow dung with vegetable waste, kitchen waste, rice straw, wheat straw and municipal waste, respectively. The maximum decrease in TOC of 51.28% and 41.18% in wheat straw and rice straw sample, respectively, suggests the highest biodegradability.
