Electrostatic Separation of Mixed Plastics Waste

A major environmental problem is mixed plastics waste. Because of the incompatibilities of the properties of different polymers, mixed waste is either land filled or reused in low value applications such as plastic wood. The barrier to economic re-use of these materials is separation into pure components. Recycled pure plastics can be used in place of virgin material and thereby much of the original value of these polymers can be gained. A dry, low cost, non-polluting process originally invented at The University of Western Ontario has been successfully scaled up to a commercial size of one tonne/hour. Several applications of this technology are explored.
