This invention relates to a method for recycling plastics, e.g. plastic films.

A method for manufacturing a polyamide B comprising melt-mixing a polyamide A and a salt C of a diacid and a diamine, wherein the polyamide B has a lower viscosity number than the polyamide A, and having a specific ratio of the ratio of the concentration of amino end groups of polyamide B to the concentration of amino end groups of polyamide A to the ratio of the concentration of carboxyl end groups of polyamide B to the concentration of carboxyl end groups of polyamide A; a polyamide B obtained by the abovementioned process; a polyamide B1 constructed from a polyamide B* and units derived from a diacid and a diamine forming the salt C; a polyamide composition comprising: the polyamide B or the polyamide B1; a filler material (D) and optionally at least one further additive (E); a polymer product comprising the polyamide B, the polyamide B1 or the polyamide composition; the use of the polyamide B, the polyamide B1 or the polyamide composition for producing polymer products; and a process for preparing a polymer product comprising the polyamide B, the polyamide B1 or the polyamide composition.

A system and method for sorting and recovery of materials in a combination of a plastics processing facility (PPF) and a plastics recovery or recycling facility (PRF) is provided. The system can include a first line comprising a polyethylene terephthalate (PET) processing line, a second line comprising a polyethylene (PE), polypropylene (PP) and polystyrene (PS) processing line, a third line comprising a plastics residuals recovery line, a fourth line comprising a fines and glass residue processing line, and a fifth line comprising a flexible plastic packaging processing line. The first line, the second line, the third line, the fourth line and the fifth line can all be located in close co-operational proximity on the same physical footprint and at the same site to process recovered plastics thus creating economies of scale and efficiency while meeting or exceeding minimum material quality specifications.
