RECYCLED POLYESTER ROUND TABLE

Polyester is a manmade fiber, synthesized from petrochemical products by a process called polymerization. With 49% of the global fiber production, polyester is the most widely used fiber in the apparel sector: more than 63,000 million tonnes of polyester fiber are produced annually. Production of polyester fabric involves significant quantities of chemicals, raw materials and by-products that are toxic and can pollute water and air and cause health issues.

Recycled polyester is promoted by Textile Exchange as a preferred fiber. It can be either mechanically or chemically recycled, with feedstock consisting of either pre- or post-consumer waste that can no longer be used for its intended purpose. This includes returns of materials from the distribution chain.
There is more to do to reach economies of scale. Challenges are still to be overcome in the factory, the marketplace, and in communities where recycling and bring-back schemes need to start.

Textile Exchange’s Recycled Polyester Working Group and its annual Round Table meeting aim to transform business – move from linear to circular, and to find solutions to technical, societal, and commercial barriers to growth.

★ Using more recycled polyester reduces our dependence on petroleum as the raw material for our fabric needs.

★ Diverting PET bottles for this process reduces landfill, and thus reduces soil contamination and air and water pollution and requires less energy than virgin polyester.

★ Garments created from recycled polyester aim to be continuously recycled with no degradation of quality, allowing us to minimize wastage. This means polyester garment manufacture could potentially become a closed loop system.

★ Solving quality issues through contaminations of various additives like antioxidants, pigments, stabilizers or anti blocking agent and shortening of the polymer chain at de-polymerization stage.

★ Finding substitutions for antimony, a polyester catalyst known to be cancer causing (potentially 500mg/kg PET).

★ Ensuring constant industrial feedstock and closing the loop by fostering feedstock from textile pre- and post consumer waste.

★ Achieving traceability and transparency in the collecting, sorting and processing with social and fair conditions.

★ Looking at lifecycle considerations: biodegradability and recyclability of polymers.

★ Outreaches to other synthetic polymers: What are the future polymers?

★ Transition towards renewable biogenic feedstock turning into technological fibers.
