NOVELTY - A waste disposal system (1) has a bio-diesel oil manufacturing apparatus (2) and a reduction gasified melting furnace (3). Waste material containing fats, oils and residue is separated from the thrown-in waste material, in the bio-diesel manufacturing apparatus and converted into fuel oil. The remaining waste material is supplied into a furnace as fuel or resource, and heated at 1000degreesC or more to produce high temperature reducing gas and liquid.    USE - Used for producing fuel oil for bio-diesel engine, high temperature reducing liquid used as road surfacing material and slag, and high temperature gas as energy source such as high temperature gas of fuel gas engine.    ADVANTAGE - The waste disposal system reduces the cost required for hydrogen fuel cell, power generation system and bio-diesel manufacturing apparatus.    DETAILED DESCRIPTION - The waste disposal system has a bio-diesel oil manufacturing apparatus and reduction gasified melting furnace. The bio-diesel oil manufacturing apparatus throws in waste material containing fats and oils such as abandoned livestock products, waste edible oil, meat, bone meal, livestock excrement and organic refuse. The waste material containing fats, oils and residue is separated from the thrown-in waste material. The fats, oils and residue are converted into fuel oil of bio diesel engine (6). The remaining waste material is supplied into reduction gasified melting furnace as fuel or resource, and heated at 1000degreesC or more to produce high temperature reducing gas and liquid. The liquid is used as slag and the gas is used as energy source such as high temperature gas of fuel gas.    DESCRIPTION OF DRAWING(S) - The figure shows the flowchart of the waste disposal system.
