ABSTRACT

 

Vegetable markets generate huge quantity of vegetable wastes. These wastes are highly perishable and serve as a source of nuisance. Unscientific disposal methods result in adverse impact on the environment and human health. Biomethanation is a microbiological treatment process and appears to be an economically viable option for the treatment of vegetable wastes. It generates biogas, a source of renewable energy and fertilizer. Different effective parameters are known to affect biogas production efficiency. The present study deals with the optimization of biomethanation process parameters (viz. hydraulic retention time, organic loading rate, pH and temperature) for vegetable wastes at 1 litre level. During the present study, hydraulic retention time of 20 days, Organic loading rate of 0.320 g VS/l.d, pH of substrate 7.0 and temperature range 36-380C were found to be optimal conditions for production of biogas from the present vegetable waste mixture
