Anaerobic digestion process of wastes containing cellulose

摘要

The present invention relates to an anaerobic digestion process of wastes containing cellulose, in which, after liquefying by bringing wastes containing cellulose in slurry state into contact with facultative anaerobic bacteria with pH adjusted between 6.5-8.0 and oxidation-reduction potential controlled between -50-300 mV with oxygen supply, the liquefied slurry is then converted into methane and carbon dioxide by bringing it into contact with obligatory anaerobic bacteria to recover methane efficiently.
