NOVELTY - A waste disposal system (10) consists of a refuse-disposal installation (11), a boiler (31), an external superheater (32), a power generation equipment (12), and a bioethanol manufacturing equipment (13). The boiler generates steam using waste heat produced in the refuse-disposal installation. The bioethanol manufacturing equipment consists of a saccharification apparatus (42) which saccharifies foodstuff waste material, and a separator (43) for separating the saccharified liquid into oil component, aqueous solution, and solid content.    USE - Waste disposal system is used for processing foodstuff waste material generated from confectioneries, convenience stores, restaurants, foodstuff factories, residence, and hospitals.    ADVANTAGE - The waste disposal system improves electric power generation efficiency by producing superheated steam using oil component produced in the bioethanol manufacturing equipment. Since ethanol solution with an ethanol concentration of 85-95 wt.% is used and a dehydration apparatus is not required, running cost is reduced.    DETAILED DESCRIPTION - A waste disposal system consists of a refuse-disposal installation which carries out melting treatment or incineration of garbage, a boiler, an external superheater, a power generation equipment, and a bioethanol manufacturing equipment. The boiler generates steam using waste heat produced in the refuse-disposal installation. The external superheater increases the steam superheat degree to produce superheated steam. The power generation equipment has a turbine (33) driven by the superheated steam. The bioethanol manufacturing equipment manufactures ethanol from foodstuff waste material. The bioethanol manufacturing equipment consists of a saccharification apparatus which saccharifies foodstuff waste material to produce saccharified liquid, and a separator for separating the saccharified liquid into oil component, aqueous solution, and solid content. The oil component is supplied to the external superheater as a fuel. INDEPENDENT CLAIMS are included for the following:    (1) waste-material processing method; and    (2) bioethanol manufacturing equipment consisting of saccharification apparatus, separator, fermentation apparatus (44) for fermenting the aqueous solution and producing ethanol fermented liquor, and a distillation apparatus (45) for distilling the ethanol fermented liquor and producing ethanol solution. The oil component and/or ethanol solution is used as fuel for the external superheater.    DESCRIPTION OF DRAWING(S) - The drawing shows a block diagram of the waste disposal system.
