DEVELOPMENT OF SMALL BIOGAS SYSTEM USING A DISPOSER FOR INDUSTRIAL-USE

抄録

Kitchen garbage from department stores and hotel restaurants is grinded by a disposer and transported to a biogas system (methane fermentation tank) via piping. Biogas produced by methane fermentation of kitchen garbage and kitchen waste water treatment sludge is used as gas fuel consumed in the process of boiler and cogeneration, and can reduce gas consumption. Based on long-term operation, energy return on investment, economy and CO2 reduction were verified.
