The constant generation of plastic wastes and their disposal generates environmental probl ems along with economic loss. In particular, mixed waste plastics are difficult to recycle bec ause of their inferior characteristics. In this work, the scale-up triboelectrostatic process for separation of various plastics from PVC has been studied. The separation efficiency of the m ixed acrylonitrile-butadienestyrene (ABS) and polyvinyl chloride (PVC) plastics considerably depended on the electrode potential (>25 kV), the air velocity (15 m/s), the relative humidity (<40%), and the splitter position (-10 cm from the center) in a scale-up triboelectrostatic se parator unit. At this time, a ABS grade of 99.5% and a recovery of 93.6% have successfully been achieved. Low-density polyethylene (LDPE), polyethylene terephthalate (PET) of over 9 9.7 grade from PVC were obtained and also general purpose polystyrene (GPPS), high density polyethylene (HDPE) and homo-polypropylene (HOMO-PP) grade of over 98.2% and a recovery of over 88.2% could be obtained.
