ABSTRACT:
Disclosed is a refuse disposal apparatus in which refuse fed into a fermenting vat can be disposed by subjecting the refuse to methane fermentation, the fermenting vat including a heating device for heating the refuse in the fermenting vat to a proper temperature for accelerated methane fermentation, and the refuse being agitated by an agitating device in the fermenting vat, so that methane produced in the fermenting vat by the methane fermentation may be externally collected by means of a gas collecting pipe for use as an everlasting heat source, and that sludge produced by the methane fermentation of the refuse in the fermenting vat may be discharged to the outside through a discharge pipe for use as fertilizer.
