Methane Fermentation of MSW and Power Genelating of Biogas

Abstract

Recycling of Municipal Solid Waste (MSW) is vigorously promoted in Japan and the necessity of energy recovery from organic waste is increasing. A methane fermentation demonstration plant for organic waste in Kyoto City is operated of about three years. Three kinds of wastes (commercial waste from hotels, yard waste and used newspaper) mixed at various ratios are used. The plant has maintained stable operations with each mixture, generating biogas by the decomposition of VS at the rate of about 820m^3_N-dry/ton-VS. Methane average content is 57.4%-dry in biogas. We obtained the technical evaluation from the Japan Waste Management Association in Sep. 2001 in terms of methane gas recovery and composting as Kompogas methane fermentation System.
