Abstract

Apparatus for use in the recovery of polyolefin plastic comprises; a three-phase decanter centrifuge means, using water as its liquid medium and an agglomeration means; wherein the three-phase decanter centrifuge means is upstream from the agglomeration means, and the centrifuge separates the polyolefin material from the source mixture such that the polyolefin material is then fed into the agglomeration means. The apparatus may be heated to 60-99.9 oC and may contain a size control means. The size control means may limit the size of material entering the centrifuge to 25 mm or less and may comprise; a screen, filter or means for reducing the size of the source material. A method of use for the apparatus is also disclosed.
