To provide a process for treating organic waste without increasing the treatment amount while crushing is carried out by using a pulper when organic waste of a plurality of kinds of different characteristics and concentrations is treated in the same treatment system and useful substances are recovered therefrom.
Slurry-like organic waste such as human waste and private sewage tank slurry is mixed with solid organic waste such as garbage and a mixture thus formed is introduced into a pulper crushing process #2, and organic solid contents are crushed by eddy flows formed by the liquid content in the mixture, and then the mixture is introduced into an anaerobic fermentation process #4 and fermented under the anaerobic conditions to recover methane gas therefrom.
