Hyosung developed recycled nylon from raw materials recovered from discarded fishing nets in 2007 and produced Global Recycled Standard-certified (GRS) 100% recycled polyester from PET (polyethylene terephthalate) bottles in 2008. Hyosung also launched Recycled Claim Standard-certified, 100% recycled Regen Spandex made with the reclaimed waste from its Spandex production in 2020. To expand beyond recycled products, it launched its United States Department of Agriculture- and SGS-certified (Société Générale de Surveillance) Regen Bio Spandex partly made from renewable resources in 2021. This year, Hyosung expanded its Regen Bio Spandex programme to include yarn offerings of higher renewable resource content, and began developing a textile-to-textile recycling programme to address circularity. What is the update on Hyosung's new Regen Bio BDO collaboration with sustainable material and technology company Geno ?
