<p>This invention relates to a method and an apparatus in the recycling of plastics, by which it becomes possible to handle and to take care of the materials in a plant without preceding sorting into different kinds of plastic. After a possible coarse sorting for removing foreign materials the waste plastic is supplied to an apparatus (5) for disintegration and washing with water containing a grease and oil emulsifying agent. Wash liquid and disintegrated material are then pumped to a tub (10) for separation by means of flotation and sedimentation. The method is particularly suited for bottles and liquid containers of plastic where a great portion of the material is comprised of polyolefines, which on account of their low density rise to the surface in the tub (10). The recycled material can be dried and granulated to be used in the manufacture of products, e.g. tubes. <IMAGE></p> |
