To provide a garbage treating method which can exhibit high-level organic matter decomposing performance and by which garbage can surely be subjected to primary fermentation.
This garbage treating method comprises a series of steps: an agitation step in which a rotary treatment tank is rotated to agitate rubbish and garbage, the treatment tank is heated and air is supplied to the treatment tank, the decomposed rubbish and garbage thrown into the treatment tank are adjusted so that the moisture content and temperature of the heated rubbish and garbage become suitable for decomposing/fermenting organic matter; a fermentation step in which the heating and the air supply are stopped, the treatment tank is rotated slowly, oxygen is supplied to the treatment tank, and the pH of oxygen-supplied rubbish and garbage is adjusted to that suitable for decomposing/fermenting organic matter; and a drying step in which the oxygen supply is stopped, the treatment tank is rotated at the speed higher than that at the agitation step, the treatment tank is heated again, air is supplied again to the treatment tank, and the rubbish and garbage are dried to have the proper moisture content.
