Abstract:

The compost, landfill waste, paddy soil and kitchen waste were used for development of microbial inoculum for the enhancement of biogas production from cattle dung under anaerobic batch conditions. Six digesters were set up containing, biogas slurry, compost, paddy soil, landfill waste and kitchen waste along with cattle dung in different concentration. The dehydrogenase activity, cellulase activity, N, P, K content, volatile solids, total solids, total volatile fatty acids, C/N ratio and biogas production was studied in samples at different time intervals. Enhanced biogas production from cattle dung supplemented with kitchen waste @ 10% was observed under anaerobic batch digestion. The maximum dehydrogenase and cellulase activities (1464.0 μg TPF g-1 sample per 24 hr and 296.2 μg glucose g-1 sample per 24 hr respectively) were found at 4th week in digester no. 6. Total volatile fatty acids, total solids and volatile solids decreased after 8 weeks of digestion. The N, P and K content was increased whereas C/N ratio was found to decrease. Supplementation of kitchen waste with cattle dung through anaerobic digestion for biogas production is cost effective and environmental friendly technology. It also improves microbial growth which enhanced biogas production during digestion.
