NOVELTY - An organic refuse is fermented by methane fermentation and methane is recovered. When the residuum has high water content, solid-liquid separation is performed and liquid is discharged and solid is processed to form an organic fertilizer. Inflammable refuse is thermolyzed using methane fuel. Metal impurities are separated and a carbonized material is obtained.    USE - For processing of organic-inflammable refuse by incineration which is useful to enhance soil.    ADVANTAGE - The organic inflammable refuse is processed without using a refuse incinerator. The processed refuse has excellent soil enhancing property. The total carbon dioxide generation amount is reduced compared to conventional method. The processing of organic-inflammable refuse inhibits dioxin and reduces the quantity of reclamation to an ultimate disposal field. The refuse is disposed without causing environmental problems.    DETAILED DESCRIPTION - An organic refuse is methane fermented using a methane fermentation apparatus and methane is recovered. When the process residuum has high water content, a solid liquid separation is performed. The liquid part is discharged after water treatment and the solid part is processed to a fertilizer using a composting apparatus to form an organic fertilizer. Inflammable refuse other than the organic refuse in the fertilizer is thermolyzed in an external treating thermal decomposition furnace using the recovered methane as fuel. Impurities such as metal is separated from solid substance residuum and a carbonized material is obtained. A portion of the carbonized material is utilized as a moisture content regulation material of the composting apparatus. The obtained organic fertilizer and the carbonized material are mixed and used as soil enhancer with a high property.
