| Résumé : |
Polyethylene terephthalate (PET) is a linear polyester that is used both in the production of plastic bottles and in the production of fibers and filaments for textile applications. PET bottles are a prime example of successful mechanical recycling, and polyester fiber and filament can likewise be recycled very well. The 2 types of input material are obtained from different sources : while PET bottles are available as post-consumer waste from bottle collection systems, polyester waste typically accrues in the form of production scrap from a textile mill. This article covers upcycling options for PET and polyester by means of mechanical recycling into pellets and reuse for polyester continuous filament. In polyester upcycling, fine filtration and IV increase are the key aspects that need to be addressed ; the article therefore provides a detailed discussion of how to optimize these steps. |
