Efficient recycling of polyester

Sustainable handling of natural resources is a global task, something that needs to be addressed now and not just in the future.

This relates in particular to the further development of the circular economy for post-consumer or post-production waste. For this reason, the recyclability of PET products made by the man-made fibre industry is attributed to special significance. For PET bottle material, the recycling of polyester materials and the possibilities for converting the waste into new high-end products within the polyester filaments, fibers and nonwovens market are state-of-the-art.

Man-made fibres and filaments made from recycled bottle flake material require corresponding single-variety collection or pre-sorting of the bottle material being recycled and comprehensive cleaning before they are shredded into polyester flakes. It is then possible to spin these flakes directly into POY filaments (DTY in the downstream process), staple fibres, nonwovens and BCF endless filaments. Today, the technology is so refined that the products achieve a quality standard that corresponds to virgin material in many applications.
