Abstract

In the treatment of mixed waste such as refuse for the separate recovery of paper and plastics sheet material scrap, in particular in recycling plants, a pre-sorted fraction containing paper and plastics sheet material scrap is treated in a pulper (1), the paper pulp suspension thus obtained is withdrawn via screens and paper fibre recovered and the screening residue containing the plastics sheet material scrap is flushed out of the pulper, comminuted at (6) after the removal of liquid at (5) and the plastics sheet material portion is separated from a liquid phase at (14). In particular, the dewatered and comminuted screening residue, after separation of the heavy matter at (7) and a further comminution at (10), is freed in a gravity floating basin (11) of the floating light-weight portion, such as wood and plastics foam material, with the exception of plastics sheet material scrap, and subsequently treated in a flow-floating basin (14) in which the plastics sheet material scrap rises to the surface of the liquid under the influence of flow and is skimmed off at 21. <IMAGE>
