A method for recycling polymeric materials, including a plurality of mechanical separation steps (B), a first density separation step (C), an intensive cleaning step (E), a second density separation step (G, V), a third density separation step (M, W) and optionally a fourth density separation step (Ga, Gb). Further less essential steps such as wetting (A), grinding (D), air flow separation (K), drying (I), electrostatic sorting (Z) and optical sorting (Za) steps may also be carried out to achieve optimised and refined separation. Polymeric materials from refuse or crushed motor vehicles may thus be separated, and polyethylene, polypropylene, polystyrene and acrylonitrile-butadiene-styrene resins may be recycled. |
