PROBLEM TO BE SOLVED: To provide a treatment method and apparatus for organic wastes which are fast in a decomposition rate of sludge, but are little in the generation amount of debris and further are large in the recovering amount of digestive gas. SOLUTION: The treatment method for the organic wastes comprises agitating the untreated sludge in an anaerobic state within a digestion tank 1 to ferment and decompose organic materials, heating a part of the sludge drawn out of the digestion tank 1 by the digestive gas produced by the decomposition through a heat exchanger 2 and returning the heated circulating sludge into the digestion tank 1. A solubilization apparatus 3 is disposed behind the heat exchanger 2 and the circulating sludge heated by the heat exchanger 2 is subjected to solubilization treatment. COPYRIGHT: (C)2005,JPO&NCIPI
