Recycled polyester : manufacturing, properties, test methods, and identification

Recycled polyesters are basically derived from the used and waste polyester bottles, old garments and industrial polyester waste, subsequently these recycled polyesters are prepared using two various methodologies such as Chemi- cal and mechanical recycling methods. There is no much difference between virgin polyesters and recycled polyesters in terms of high strength, durability, versatility, and performance. As the Co2 emission is less in the production of recycled polyesters, it does not pose any threat to the environment. This polyester also reduces the wastage of petroleum fuels which is a major constituent in the production of polyesters, More- over, it leads to a reduction of overall carbon foot print of the polyester production. The recycled polyesters possess outstanding and enhanced mechanical and thermal properties. This chapter depicts the various fantabulous properties and characteristics of recycled polyesters in detail.
