The Global Recycled Standard (GRS) was originally developed by Control Union Certifications in 2008. Responsibility passed to the Textile Exchange on January 1, 2011. The GRS is an international, voluntary, full-fledged product standard that sets out requirements for independent certification of recycled materials, chain of custody, social and environmental practices, and chemical restrictions.
The Global Recycled Standard (GRS) aims to record the exact percentage of recycled materials in products and to make the composition more transparent. Overall, the standard aims to increase the use of recycled materials in the manufacture of textile products.
The recycled basis is industrial waste (pre-consumer waste) and waste generated by private end use (post-consumer waste). Among other things, GRS ensures that the recycled materials can be traced back exactly. It also sets standards for production to reduce harmful effects on people and the environment. GRS stands for the the social component between man and nature.
The GRS logo itself may only be used if the recycled content is at least 50%.
The standard is international, voluntary and fully fledged. It also provides guidelines on the additives used, environmental management and social responsibility and does not end with the raw materials themselves.
