Abstract
Treatment of solid waste by anaerobic digestion is a promising process of recovering and saving energy. Present study aims to estimate the mesophilic digestion of municipal solid waste by using batch scale laboratory reactors (acrylic bottle) having each bottle capacity 20 L for 90 days at room temperature, with two different inoculum sources such as Cow dung slurry and sewage sludge. Proportion of inoculum used for acidogenic fermentation of organic waste is about 30 % of operating volume of substrate. Cumulative biogas production achieved for the reactor with sewage sludge as inoculum was 457 ml/gVS and for cow dung as inoculum was 487 ml/gVS.
