In this study, we carried out the research on material separation for recycling of ABS and PBT mixture plastic waste by triboelectrostatic separation. From the research on charging characteristic for choice of charging materials for removal of PBT from ABS, it was found that PP was optimum charging material to make high charging amount with opposite polarity for ABS and PBT mixture plastic waste. Therefore, we manufactured a charger of pipe line type using PP material for separation of ABS and PBT mixture plastic waste. At optimum test conditions that used PP pipe line charger developed in this study, we developed a triboelectrostatic separation technique that can removal PBT over 99.9% and recover ABS up to 92.5%. From this study, we established the material separation technique that can recycle ABS material from ABS and PBT mixture plastic waste.
