NOVELTY - Electrical power generated using biogas from methane fermenter (3) is supplied to organic refuse processing facility (1), and waste heat is supplied to composting equipment (7). The fermented liquor is solid-liquid separated. The supernatant liquid is purified and discharged, therefore processing the organic refuse and livestock dung.    USE - The method is useful for processing organic refuse and livestock dung, for electrical power generation.    ADVANTAGE - The electrical power necessary for driving the organic refuse processing facility and composting equipment is supplied by converting the biogas from fermenter into electricity. Therefore, administrative and maintenance costs are reduced, and the energy is effectively used. The scum of fermented liquor is composted along with the livestock dung, and therefore there is no garbage disposal problem.    DETAILED DESCRIPTION - Organic refuse is processed by methane fermenter in organic-refuse processing facility, and livestock dung is processed in composting equipment. Electricity is generated in electricity-generation units (6) using biogas generated in the fermenter as fuel. The electrical power is supplied to facility (1), and the waste heat emitted from units (6) is supplied to equipment (7). The fermented liquor is solid-liquid separated in solid-liquid separation processor (4). The supernatant liquid of the liquor is purified and discharged by purified-treatment system (5). The scum separated from the fermented liquor is combined with livestock dung and composted, therefore processing the organic refuse and dung.
