WASTE TREATMENT SYSTEM AND METHOD, AND BIOETHANOL PRODUCTION FACILITY

摘要

PROBLEM TO BE SOLVED: To provide a waste treatment system and method for collecting oil from food waste of waste materials and effectively using it as the fuel of an external superheater, and to provide a bioethanol production facility.;SOLUTION: The waste treatment system 10 includes: a garbage disposal facility 11 for performing incineration treatment or melting treatment on garbage; a power generation facility 12 having a boiler 31 which generates steam, using a waste heat generated in the garbage disposal facility 11, the external superheater 32 which generates superheated steam by further rasing the degree of superheating of the steam, and a turbine 33 which is driven by the superheated steam; and the bioethanol production facility 13 for producing ethanol from food waste. The bioethanol production facility 13 includes: a saccharification device 42 which generates a saccharified solution by saccharifying the food waste; and a separation device 43 which separates the saccharified solution into oil, aqueous solution and solid. The oil is supplied to the external superheater 32 as the fuel of the external superheater 32.;COPYRIGHT: (C)2012,JPO&INPIT
