An apparatus for separating a specified plastic from other kinds was devised. It consisted of a triboelectric section and a separating section with both polarities. Various plastic sheets were frictionally electrified in the fluidized bed and then were blown off into the electrode unit, in which they were separated according to their own polarity.
The recovery of plastics was more than 70% beyond the electric field strength of 100kV/m, and the weight ratio of recovered plastics was more than 80% in the separation of the four kinds of plastics.
