PROBLEM TO BE SOLVED : To improve a degradation efficiency of organic waste by carrying out again an anaerobic digestion to persistent solid materials separated by a solid-liquid separation apparatus and scrapped heretofore.
SOLUTION : The organic waste is anaerobic-digested in an anaerobic digester chamber 2, the effluent from the anaerobic digester chamber 2 is solid-liquid separated in the solid-liquid separation apparatus 3, and the persistent solid materials 13 separated by the solid-liquid separation apparatus 3 are sent to the anaerobic digester chamber 2 or a dry type anaerobic digester chamber 5 to carry out a re-decomposition. Further, when a dry type anaerobic digestion is carried out to the persistent solid materials 13 solid-liquid separated, a previously-carried out anaerobic digestion prevents a generation of VFA to improve the degradation efficiency.
