Mechanical or chemical recycling of post-consumer or post-industrial polyester
Mechanical recycling of polyester waste material is often done by shredding – washing - melting and this results in new polyester grades. These grades are used for packaging, strapping, monofilaments, high tenacity yarns, fibers and other high demanding technical applications.
With mechnical recycling the colour of the extruded output (polyester grades) follows from the colour of the waste input: clear PET bottles will lead to clear new material. Because mechanical recycling has the highest CO₂ reduction figures we are also exploring mechanical recycling of other polyester waste streams like polyester textiles and carpets.
In 2013, we started with the recycling of post-consumer bottles, back into a grade suitable for direct food contact and the development of special grades based on recycled materials. Nowadays, 60% of our capacity is occupied with the upgrading of recycled PET and 40% with virgin specialties with experience in PET, Copolyesters, PBT, PEF, etc.
Each day we recycle 1 million PET bottles into valuable, food contact approved polyester grades (rPET). We are continuously expanding and improving our processes and know-how of mechanical recycling.
