GRS – Global Recycled Standard
GRS is an international, voluntary product standard that verifies recycled content, chain of custody, social and environmental practices, and chemical restrictions. Designed for companies processing or trading products with recycled materials, GRS certification through Control Union provides third-party verification of sustainability claims and responsible production.
About GRS
The Global Recycled Standard sets comprehensive requirements for recycled content verification (minimum 50%), chain of custody tracking, social responsibility, environmental practices, and chemical restrictions. Companies across textiles, plastics, and other industries choose GRS certification to substantiate quality claims, meet customer demands for verified sustainable products, and enhance market credibility.
As the original developer of GRS in 2008, Control Union offers expert certification services through our global network spanning 80+ countries. Our ability to combine GRS with other certifications creates efficiency and cost savings, while our extensive experience and knowledge support your organisation as a sustainability leader.
