Abstract

PROBLEM TO BE SOLVED: To provide a method of treating garbage/combustible refuse by which the generation of CO2 which causes global warming is reduced, the risk of generating dioxin is restrained, and the quantity of final landfil disposal is reduced. SOLUTION: Garbage 1 is subjected to methane fermentation treatment by a methane fermenter 1A to recover methane. After the treated residue is subjected to fertilization treatment by a fertilization device 1B, impurities 1b are separated to obtain an organic fertilizer 1a. Combustible refuse 2 other than the garbage is pyrolytically decomposed in a pyrolytically decomposing furnace 2A to recover pyrolisis gas 2c and separate impurities 2b from solid residue to obtain carbide 2a. The obtained organic fertilizer 1a and carbide 2a are mixed to obtain a soil conditioner 3 high in performance. Heat sources of warm air 3a for heating the methane fermenter 1A and warm air 3b for heating the pyrolytically decomposing furnace 2A are fed from a gas combustion furnace 3A using methane 1c and the pyrolisis gas 2c as fuel.
