Swedish recycling firm Renewcell has signed a letter of intent to collaborate with Eastman to develop Naia Renew ES yarns sourced from Circulose, Renewcell’s 100 percent recycled textile raw material. This is Renewcell’s first agreement with a U.S.-based fiber producer. Renewcell has described the deal as “an important step in developing the first acetate-based applications to use Circulose feedstock.” Eastman has said that the agreement is at the heart of its strategy to lower its reliance on virgin feedstocks and to launch a portfolio of products with increased recycled content.

Circulose is a 100 percent recycled, recyclable and biodegradable material made from 100 percent textile waste, such as worn-out clothes and production scraps. Eastman’s Naia cellulosic staple fiber, filament yarn and Naia Renew products provide sustainable choices for fabrics used in ready-to-wear, sweaters, loungewear and casual wear. Naia is sourced from sustainably managed pine and eucalyptus forests. Naia Renew’s recycled content is obtained by the allocation of recycled plastics through a mass balance process with International Sustainability and Carbon Certification (ISCC).
