Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a method for effectively treating waste plastics without producing chlorine or the like. SOLUTION: The method for treating waste plastics comprises the step of charging the waste plastics 11 into a cylindrical oven body 12 packed with granular or lumpy CaCO313, the step of pyrolyzing the waste plastics at 320-660°C in the oven body to produce oil vapor and concurrently adsorbing an acid gas produced during the pyrolysis onto the surface of the CaCO313, and the step of extracting the oil vapor from the oven body and cooling the oil vapor to room temperature to obtain a liquid oil, and preferably furthermore, the step of dechlorinating chlorine-based polymers in the waste plastics. In this method, it is more preferable that the oven body is packed with metallic or ceramic balls 23 together with the CaCO313. It is preferable that the treatment plant has the following construction: Partition plates 22 for hindering the movement of the CaCO3in the oven body are set in the oven body and there are provided a plurality of scraping plates 24 for scraping up the balls together with the CaCO3by turning them on the circumferential wall inside the oven body.
