Naia Renew Achieves GRS Certification for Sustainable Fabrics

Naia Renew cellulosic fiber achieved the esteemed Global Recycled Standard (GRS) certification for its use of sustainable fabrics.

Last week, Eastman’s Naia Renew cellulosic fiber attained the prestigious Global Recycled Standard (GRS) certification. This is a third-party validation for recycled content in textiles. This certification covers Naia Renew’s recycled content, chain of custody, social and environmental practices, as well as chemical restrictions.

The GRS certification process is overseen by Textile Exchange, a global non-profit dedicated to promoting sustainable change in the fashion and textile industry. Conducted through an audit by the independent certifying body SCS Global Services, this certification spans the entire supply chain, ensuring compliance with traceability, environmental principles, social requirements, chemical content, and labeling standards.

Advancing Sustainable Fabrics

Claudia de Witte, the sustainability leader for Eastman textiles, expressed pride in achieving GRS certification, stating, “We’re honored to add GRS certification to our list of Naia certifications that support our sustainability goals. Third-party certifications help us build our brand trustworthiness. It’s our goal to make sustainable textiles available to all, and we do that by building trust with our customers and collaborators. This certification adds even more credibility to our fibers and our sustainability story, which we’re proud to share.”

In June 2023, Textile Exchange expanded its Alternative Volume Reconciliation (VR2) policy. It now encompasses a broader range of chemical recycling technologies eligible for mass balance. Notably, this extension now includes gasification, the technical description of Eastman’s molecular recycling technology known as carbon renewal technology. Eastman collaborated with Textile Exchange and other stakeholders to highlight the value and contribution of its molecular recycling technology. This policy update is pivotal for Eastman as it allows the company’s innovative material-to-material recycling technology to undergo GRS certification audits.

Eastman’s Molecular Recycling and Naia Renew’s Circular Commitment

Molecular recycling technologies at Eastman break waste down into its molecular building blocks. This enables the creation of new materials indistinguishable from non-recycled counterparts. By incorporating gasification, GRS now embraces a broader approach to making sustainable textiles accessible to a wider audience.

Eastman’s molecular recycling serves as a complementary solution to mechanical recycling. Particularly effective for hard-to-recycle waste materials, including textiles with complex factors such as fiber blends, chemicals, and additives, Eastman’s Naia Renew is produced from 60% sustainably sourced wood pulp and 40% GRS-certified waste materials. The GRS certification verifies the chemical recycling, concentrating, extrusion, and spinning processes of the undyed yarns and fibers. It also solidifies Naia Renew’s commitment to sustainable and circular textile production.
