Abstract

The parent patent described recovery of plastics materials by grinding followed by floatation to separate off paper and other contaiminating materials. The process is modified by pretreatment to remove at least some of the paper prior to the treatments previously described. The treatment may be physical, chemical or biological. The process is used for recovering materials such as PVC in sufficient purity for extrusion from powder or flake to profiles without surface imperfections.
