Then the discharged solids are screened by a screening means 4 to remove metals 5 which are not granulated. The remaining materials are supplied to a pyrolysis furnace 6 where the materials are thermally decomposed at 400W1,000°C. Hydrogen chloride evolved in the pyrolysis is neutralized with the lime preset in the granulating material 2 to form CaCl 2  which is then removed as a residue 9. Hydrocarbons produced by the thermal decomposition are fed to a purifier 7 where cooling, washing and separation are carried out to obtain the desired fuel. In this way, the fuel can be produced from the waste plastic without causing environmental pollution and the corrosion of the apparatus.
