Provided are a recycling system, a recycling method, and a laminate separation and recovery method, in which a wet crushing facility capable of crushing a laminate in water and separating the laminate simultaneously with the crushing. The recycling system according to the invention is a recycling system for recycling a plastic laminate having at least two or more layers into a recycled material, the recycling system including: a wet crushing facility configured to separate the laminate into single layers while crushing the laminate in water by performing pressure feeding simultaneously with crushing; and a facility configured to dispense and recover a crushed mixture of each of the separated single layers.

The invention relates to thermoplastic molding compositions (T) comprising 10 to 99% by weight, based on the total weight of the molding composition (T), of at least one type of recycled polymer material (A), containing 20 to 100% by weight, based on recycled material (A), of recycled acrylonitrile-butadiene-styrene copolymer (A1); up to 80% by weight of at least one recycled styrene-acrylonitrile copolymer (A2); up to 10% by weight of recycled polymeric impurities (A3), different from (A1) and (A2); 0.1 to 30% by weight, based on the total weight of the molding composition (T), of at least one graft copolymer (B), different from (A); 0.1 to 18% by weight, based on the molding composition (T), of block copolymer (C); and optionally up to 89.8% by weight of further polymer component (D), different from (A), (B) and (C); optionally up to 30% by weight of filler and/or reinforcing agent (E); and optionally up to 30% by weight of further additive (F).

Disclosed is a device for processing plastic materials, having a shredding unit, a conveying unit having a screw (7), and an extruder, having at least one extruder screw (11), adjoining the screw, wherein the central longitudinal axis (3) of the screw (7) is oriented at an angle to the central longitudinal axis (10) of the extruder screw (11), in particular at an angle of 80° to 100°, preferably 90°, and the longitudinal axis (3) of the screw (7) is offset with respect to the longitudinal axis (10) of the extruder screw (11) by an offset (v) in the direction of the direction of rotation (12) of the extruder screw (11) at or in the region of the discharge opening (8) or the intake opening (16) of the conveying unit.

The invention relates to a process for devulcanizing a vulcanized rubber mixture, comprising the following steps: A) providing or producing a vulcanized rubber mixture, B) comminuting the vulcanized rubber mixture to a granular material composed of vulcanized rubber particles, where the vulcanized rubber particles have a maximum particle diameter of 100 mm, C) extruding the vulcanized rubber particles produced in step B) in a twin-screw extruder at a shear rate of less than 100 s.sup.−1, where the temperature of the vulcanized rubber particles during extrusion is less than 200° C., to give a devulcanized rubber mixture having a temperature above 100° C., D) cooling the devulcanized rubber mixture in a further kneading unit, so as to give a devulcanized rubber mixture having a temperature in the range from 50° C. to 100° C. The invention further relates to an apparatus for performing the process and to the use of the apparatus for devulcanization of a vulcanized rubber mixture.

Methods and apparatus are provided for the separation of a feedstock stream comprising a principle component and at least one secondary component such that at least one component has greater friability that the others using a rotary impact separator. The methods allow the recovery of two or more streams, one rich in the more friable component, and one lean in the more friable component.
