NOVELTY - Plastic garbage (32) is separately collected, chloroethylene is removed from garbage, and garbage is thrown into garbage collection pit (2). Wastewater (9) collected in bilge pit (3) attached to pit (2) is separately heat-processed with offline, without supplying to drying furnace. Biomass material is mixed with refuse. Refuse with combustible refuse (31) and plastic garbage is separately recovered. A bark material (36) is added and mixed with refuse. Powdery municipal solid waste is dried, pulverized, classified, supplied to a molding machine and compressed to obtain solid fuel (13).    USE - Manufacture of solid fuel used as fossil fuel.    ADVANTAGE - The solid fuel with reduced chlorine content is efficiently manufactured with improved moldability without affecting environment.    DETAILED DESCRIPTION - Powdery municipal solid waste is dried, pulverized, classified and supplied to a molding machine (12) through a garbage collection unit, a primary crushing selecting unit (17), a drying furnace (8) and a secondary crushing selecting unit (18). The obtained product is compressed to obtain a predetermined shape solid fuel. Plastic garbage is separately collected, chloroethylene is removed from garbage, and garbage is thrown into garbage collection pit. Wastewater collected in bilge pit attached to garbage collection pit is separately heat-processed with offline, without supplying to drying furnace. Biomass material is mixed with refuse. Refuse with combustible refuse and plastic garbage is separately recovered. A bark material is added and mixed with the refuse. The content of chlorine in solid fuel is reduced to 0.3 %mass or less.    DESCRIPTION OF DRAWING(S) - The drawing shows the schematic view of manufacturing plant of solid fuel.
