<p>PROBLEM TO BE SOLVED: To provide a method for recycling hybrid-type plastics by which the recycling rate of a material of nonindustrial waste-based plastics disposed from a household is heightened, the plastics can be reused as a reclaimed material having a high additional value, the amount of a residue discharged to the outside of the system can be reduced, and the amount of the recovered formed oil can be increased. SOLUTION: This method for recycling the hybrid-type plastics comprises manually selecting the waste plastics to recycling raw materials of each separated polyethylene, polypropylene, polystyrene and polyethylene terephthalate, and oil-forming raw materials comprising other mixed plastics in a step for sorting mixed various kinds of the waste plastics received in an installation, removing foreign matters from the product at a wet gravity selecting step 8 after crushing each material of the recycling raw materials at a crushing step 7, granulating each crushed material at a granulating step 11 after removing the foreign matters to provide material-recycling products, crushing the oil-forming raw materials 4 at the crushing step 7, removing iron materials and aluminum materials from the crushed product at a magnetic selecting step 13 and an aluminum-selecting step 14, subjecting the iron materials and aluminum materials-removed product to a vinyl chloride-removing treatment at the wet gravity selecting step 8, and forming the product obtained at the foregoing step 8 into the oil at a thermal cracking and oil-forming step 18.</p> |
