Post-consumer recycled PCR

Reprocessing of post-consumer recyclate (PCR) by exposing it to shear and heat stress produces polyolefins that have lower elongation at break, lower impact strength and less stiffness than required, due to the low re-... [Pg.211]

In this chapter the technical as well as legislative aspects of mechanical (secondary) recycling of post-consumer plastics will be described. For packaging materials containing a certain amount of PCR plastics the most important point is the migration of the suspicious compounds from the polymer. [Pg.206]

One crucial parameter for the evaluation of a super-clean recycling process producing a recyclate suitable for food contact is the contamination level of the input material. Due to the fact that diffusion is a reversible process, the higher diffusive polymer types should have higher input levels of post-consumer contaminants. The first step in the evaluation of PCR polymer should therefore be the determination of the input concentrations of post-consumer compounds in the polymer materials. Eor a review of concentration of post-consumer compounds in packaging materials intended for recycling see ref. 8. [Pg.208]

Class 2 PCR material which had been used for food packaging for well-known applications and re-collected pure-grade by the recycler, for instance, via a deposit system. This material typically contains only post-consumer food packaging materials. Due to its post-consumer character, the recycler usually does not have complete control of the plastics material over the time period from its first use up to its return. [Pg.209]

In 1993, collaboration between Patagonia and Malden Mills (now Polartec) led to the early development of recycled polyester fibre (from Wellman Inc.) for use in Synchilla fleece made from plastic soda bottles that diverted waste from landfills. Later, PCR filament yam was made for linings and shell fabrics from 30% to 50% post-consumer materials (bottles, polyester uniforms, tents and garments) with the remainder sourced from post-industrial waste. Clothes, at end of life, if constituted from one fibre type, can be recyclable. In theory, consumers may return a polyester garment to be forwarded to a processor to be re-made into fibre or downgraded to other forms of plastic. [Pg.31]

Post-industrial recycled plastics occur in most plastic products, wherein the plastics from the sprues runners, extrudate, etc. are added back into the virgin plastic at the plastic manufacturing plant. Postconsumer resin (PCR) refers to plastics that were made into products, for example, bottles, bags, film, packaging, used by a consumer, collected by a waste disposal company, processed into recycled pellets at an MRF, where the recycled plastic parts are converted into recycled plastic pellets. The plastic pellets are then sold to plastic companies. [Pg.117]
