<p>PROBLEM TO BE SOLVED: To provide a system for converting waste-plastic into oil which reduces the energy basic unit and liquefaction cost and can reuse a decomposition gas, etc., released from a liquefaction process. SOLUTION: This system comprises a melting vessel 4 for melting waste plastics, a pyrolysis vessel 7 for pyrolizing the waste plastics melted at the melting vessel 4 to produce a pyrolysis gas, and a regenerating mechanism D for generating a regenerated gas or a regenerated oil from the pyrolysis gas produced at the pyrolysis vessel 7. Adjacent to this system, a waste plastic incineration system B equipped with an incineration oven 8 for incinerating waste plastics is installed, and a waste heat supply mechanism C is installed for supplying a waste heat generated at the incineration system B as a heat source to the pyrolysis vessel 7.</p> |
