Anaerobic digestion is the biodegradation of the organic waste with the aid of bacteria which performs it work in the absence of oxygen. The main objective of anaerobic digestion is the degradation and destruction of organic substances, with consequent reduction of the pathogens. & odorous emissions. Anaerobic digestion process consists of four major steps: hydrolysis, acidogenesis, acetogenesis an methanogenesis vegetable wastes are a fine substrate with possibility to produce methane and are

A careful consideration when selecting the working method parameter such, organic loading rate (OLR), C/N ratio, Gas production rate inoculums to substrate ration (ISR) temperature & pressure hydraulic retention time, Electricity generation calculations are given. Improvement in C/N ratio, higher bio-degradability, effective volatile solids (VS) elimination, ecofriendly sludge production has been regarded as advantage of co-digestion process.
