NOVELTY - The plant has pre-processing line that classifies waste material into flammable and nonflammable. A portion of wood made to-be-processed object is mixed with fermented material by mixing line to form mixed waste. Mixed waste is dried by heat generated during aerobic fermentation performed by fermentation dyeing store (43). Fermentation-drying line is included with deodorizing unit (44) for deodorizing air in dyeing store. The condensed water is produced while deodorizing air in dyeing store, and added to mixed waste whose moisture content is adjusted to preset level by mixing line.    USE - Recycling plant of municipal solid waste discharged from home or office.    ADVANTAGE - Since water circulates through the wooden piece by fermentation chamber water sprinkling unit, the odor of fermentation chamber is deodorized effectively and fermentation microbe is cultured effectively. Since the fermentation dry line of the recycling plant dries a waste material with the heat accompanying the fermentation of waste material, the need for obtaining the heat for drying the waste material by burning RPF is avoided and the producibility of RPF which is a product of the recycling plant is improved. The fermentation chamber is maintained at a negative pressure by inducing the air containing the water vapor of the fermentation chamber to the water-storage chamber by the air blower, so that the spreading of odor in the fermentation chamber to the outer side of fermentation dyeing store is prevented.    DETAILED DESCRIPTION - The lightweight article is classified from to-be-processed object fermented and dried by fermentation-drying line. A shaping apparatus is provided for mixing lightweight article with flammable materials so as to produce a solid fuel. A fine-grain fraction is classified from the to-be-processed object fermented and dried by fermentation-drying line, and used for producing compost. The pre-processing line is included with metal removal apparatus for removing a metal from waste material. The portion of to-be-processed object is returned before removing metal from waste material by metal removal apparatus and mixed with a fermented material. A fermentation chamber (155) is provided for mounting and accommodating to-be-processed object on the floor surface featured with air permeability and water-permeability. A water-storage chamber (154) which receives the leachate effused from the to-be-processed object is arranged on the below the fermentation chamber. A sprinkler nozzle (156) is provided to spread the water of fermentation water-storage chamber to the to-be-processed object of fermentation chamber. A fermentation chamber air-circulation unit is provided to guide the air of fermentation chamber to fermentation water-storage chamber. The floor surface of deodorizing chamber (166) is mounted with the wooden piece.    DESCRIPTION OF DRAWING(S) - The drawing shows a cross-sectional view of the fermentation dry installation.
