METHOD FOR TREATING GARBAGE AND BURNABLE TRASH

摘要

PROBLEM TO BE SOLVED: To provide a method for treating garbage and burnable trash, capable of reducing generation of CO2 causing global warming and reducing final landfill. SOLUTION: The garbage (1) is subjected to a methane fermentation treatment by a methane fermentation device (1A) to recover methane (1b) and the residue of the treatment is composted by a composting device (1B) to make an organic fertilizer (1a). The burnable trash (2) other than the garbage is pyrolyzed by an external heating pyrolyzer (2A) using the methane (1b) obtained by the methane fermentation and separated from impurities (2c) such as metals, tiles and pebbles to obtain a carbonized material (2a). A part of the carbonized material is utilized as a moisture control material for composting treatment of the methane fermentation residue. The obtained organic fertilizer (1a) and the carbonized material (2a) are mixed to obtain a high-performance soil modifier (3).
