An apparatus for continuously separating specific plastic from plastic mixtures was devised. The apparatus consisted of a triboelectric section and an electrostatic separating section according to their polarities. Various plastic sheets were frictionally electrified in the first fluidized bed and then introduced into the second fluidized bed where plastic sheets were blown off into the electrostatic separation unit. The recovery of plastics was more than 70% for polyvinyl chloride, and 80% for other plastic sheets. The purity of recovered plastics was more than 90% for polyvinyl chloride, and 70% for other plastic sheets. The separation performance of a continuous flow apparatus was slightly lower than that of batch operation.
