NOVELTY - A manufacturing plant (1) of solid fuel having waste material has crusher for crushing plastic and organic group substance (S), dryer for drying crushed product, extruders (2,4), transfer apparatus, pelletizer and solidification apparatus. The extruder (2) carries out heat-mixing of substance (S), and mixture of crushed plastic and extruded substance (S) is transferred, extruded, pelletized, and solidified to manufacture solid fuel.    USE - For manufacturing waste material-containing solid fuel such as refuse-derived fuel.    ADVANTAGE - The manufacturing plant of solid fuel containing waste material, is eco-friendly. The byproduct gas produced during manufacture of solid fuel, is easily discharged through neutralization apparatus such as deodorization device.    DETAILED DESCRIPTION - A manufacturing plant of solid fuel consisting of waste material has a crusher, a drying machine, extruders (I,II), a transfer apparatus (3), a pelletizer and a solidification apparatus. The crusher crushes plastic and organic group substance (S), after separation. The drying machine dries the crushed plastic and organic group substance. The extruder (2) carries out heat-mixing of substance (S), and extrudes from nozzle hole in carbonized state. The transfer apparatus transfers the mixture of crushed plastic and extruded substance (S). The transferred mixture is heat-melted, extruded in extruder (4), pelletized, and solidified to manufacture solid fuel consisting of waste material.    An INDEPENDENT CLAIM is included for solid fuel consisting of waste material. The organic group substance (S) (10-70 wt.%) extruded from nozzle hole in carbonized state, and fragmented pellet-form plastic waste (30-90 wt.%) are mixed, melt-kneaded by extruder (4), and poured into a metallic mold cavity for solidification of predetermined shape.    DESCRIPTION OF DRAWING(S) - The figure shows a profile view of manufacturing plant of solid fuel consisting of waste material.    manufacturing plant of solid fuel (1)    extruders (2,4)    transfer apparatus (3)    metallic mold for solidification (5)    water tank (6)    solid fuel (7)
