Zusammenfassung:	PURPOSE:To inexpensively recover a large amt. of oil-component by adding polystyrene, PP and polybutadiene resins alone or the mixture composed thereof to plastic waste, adjusting the mixture and stably executing the dry distillation of the above-mentioned waste at a low temp. CONSTITUTION:The polystyrene, PP and polybutadiene resins alone or the mixture composed thereof is added to the plastic waste and is so adjusted that the ratio of the mixture is 10wt%, more preferably 30wt%. Such waste is dry-distilled at 200-450 deg.C by which the oil-component is gathered. As a result, the stable dry distillation of the plastic waste at the low temp. is made possible and the inexpensive recovery of a large amt. of the oil-component is made possible.
