<p>PURPOSE:To recover a curable resin part, etc., and reutilize the recovered part, etc., as a fuel, etc., by blending a waste plastic with a specific mixture in a specified proportion, heating the resultant blend at a specific temperature or above and efficiently liquefying a matrix constituting the waste plastics. CONSTITUTION:This method for liquefying waste plastics is to blend (A) 100 pts.wt. waste plastic such as an FRP molding with (B) 30-500 pts.wt. mixture of (i) a hydrocarbon, having >=180 deg.C/760mmHg boiling point and containing >=1 benzene nuclei such as diethylbenzene with (ii) a polyhydric alcohol having >=180 deg.C/760mmHg boiling point and >=2 hydroxyl groups in one molecule such as diethylene glycol [at preferably (30-99)/(1-30) blending ratio of the components (i)/(ii) expressed in terms of weight ratio] and then heat the resultant blend at >=180 deg.C.</p> |
