Eastman’s Naia Renew is produced from 60% sustainably sourced wood pulp and 40% GRS-certified waste materials.

The company added that its molecular recycling complements mechanical recycling and offers a solution for hard-to-recycle waste materials, including textiles affected by factors like fibre blends, chemicals and additives.

Naia product manager Jason Keller said: “This first production represents years of work by our team. Our customers have been asking when we’d have GRS certification, and we’ve worked tirelessly to make Naia Renew certified. We’re so proud to offer not just a sustainable product but a certification of the fibre that establishes trust with our collaborating brands.”

Eastman believes the GRS certification process, which is owned by Textile Exchange, plays a vital role in driving sustainable change in the fashion and textiles industry.
