<p><P>PROBLEM TO BE SOLVED: To provide a plastic sorting method which is capable of efficiently sorting plastics where chlorine containing plastics have been excluded from waste plastics and the like mixed with various types of plastics without necessitating a particular heating device, a generation device of ozone and the like. <P>SOLUTION: In the plastic sorting method to separate the chlorine containing plastics from the mixture of plastics, it comprises the steps of sorting and collecting plastics with high specific gravity by performing the specific gravity separation, then drying the plastics with high specific gravity sorted and collected and further performing the wet type specific gravity separation of the dried plastics with high specific gravity to sort and collect the plastics of the precipitation side. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
