Abstract
In this study, we carried out the research on triboelectrostatic separation for heavy group plastics (PET, PVC) recovered from wet gravity separation. From the research on charging characteristic for the choice of charging materials, it was found that PP was optimum charging material to make high charging amount with opposite polarity for PET and PVC of heavy group. Therefore, we manufactured a charger of cyclone type using PP material for separation of PET and PVC. At optimum test conditions that used PP cyclone charger developed in this study, we developed a triboelectrostatic separation technique that can separate PET plastic up to grade of 98.5% and recovery of 86.2%. We established new separation technology that could recycle the PET and PVC heavy group plastics recovered from wet gravity separation.
