Fashion retailer C&A has launched what it claims are the world’s most sustainably made Cradle-to-Cradle Certified jeans.

The jeans use Roica V550 and Roica EF spandex yarns, part of the Roica Eco-Smart family of premium stretch yarns from Japanese fibres business Asahi Kasei. The Roica V550 stretch yarn has held Cradle-to-Cradle Certification since 2016 and so was chosen for C&A’s C2C Certified jeans programme. It has the C2C Gold Level material health certificate, and is also a Hohenstein Environment Certificated yarn that breaks down at its end-of-life without releasing any harmful materials.

The second yarn, Roica EF, is GRS (Global Recycled Standard) certified, made through the recycled technology using more than 50% pre-consumer waste in manufacture.

“Both yarns play their special ingredient roles in products that are part of Circular Economy product development, helping to create modern wardrobe solutions that are smart, responsibly made and designed affordably for everyday life,” C&A says.
