The invention relates to a method for recycling respiratory protection masks comprising a plurality of layers manufactured from a single thermoplastic polymer chosen from polypropylene, polyethylene terephthalate, polylactic acid, homopolymers and copolymers of polyamide 6 (PA6) and long-chain polyamides such as PA11 or PA12, and comprising a filtration layer made of polyvinylidene fluoride.

Processes and facilities for using one or more PET-containing materials as a feedstock to a chemical recycling facility, and in particular a solvolysis facility, are provided herein. The PET-containing materials used as feedstock may comprise a quantity of PET-containing solidified purge material. The PET-containing solidified purge material may be derived from various processes and facilities, including PET reclaimer facilities, manufacturers of PET articles, and/or a polymer manufacturing facilities. For example, he purge material may be the solidified purge material from an extrusion and/or pelletization process. Such solidified purge materials are generally undesirable or unusable to mechanical PET recycling facilities, and typically are sent to landfills and/or incinerators. However, the processes and facilities described herein make use of the PET and other plastics present in these otherwise undesirable or unusable solidified purge materials.

The present invention relates to a recycling process for a laminate and a solution used in such a process. The present invention finds particular application in the removal of an adhered overlay from an underlying substrate material such as plastic. The process includes subjecting the laminate to an impact frictional striking force, thereby substantially separating the substrate layer from the one or more surface layers of the overlay and then washing the substrate layer with a washing solution to remove the remaining surface layers of the overlay and glue from the substrate layer. The washing solution may be an aqueous solution including a surfactant, a solvent and a base.

A shredding assembly for tearing a plastic article, such as waste bottles into pieces or pellets. The shredding assembly includes rails that can be installed at a height and a shredder. The shredder includes a housing mounted on the rails and can slide from a stowed position to over one or more trash bins. The shredder includes two rollers mounted within the housing and a drive mechanism for counter-rotating the two rollers.

The present invention provides a flame-retardant styrene polymer composition comprising an organic bromine compound, zinc stearate and calcium stearate, the use for preparing styrene polymer films or foams and a process for recycling of styrene polymer-containing scrap.

A system and method for processing an artificial turf, and a product produced by the method, is provided. The method includes providing an artificial turf having an infill, separating at least a portion of the infill from the artificial turf, downsizing the artificial turf into artificial turf fragments and rotationally mixing and translating, by a melt system, the artificial turf fragments at a pressure less than a maximum predefined pressure to form a melt. The maximum predefined pressure is between about 0.08 - 20 bar.

Processes and facilities for using one or more PET-containing materials as a feedstock to a chemical recycling facility, and in particular a solvolysis facility, are provided herein. The PET-containing materials used as feedstock may comprise a quantity of PET-containing dry fines. The PET-containing dry fines may be derived from various processes and facilities, including PET reclaimer facilities and/or manufacturers of PET articles. For example, the dry fines may be collected from solid-liquid separators and/or dust collectors from processes that include conveying, drying, densification, centrifugation processes, and/or grinding PET-containing plastic material. Such dry fines are generally undesirable or unusable to mechanical PET recycling facilities, and typically are sent to landfills and/or incinerators. However, the processes and facilities described herein make use of the PET and other plastics present in these otherwise undesirable or unusable dry fines.
