The Global Recycle Standard (GRS) is a voluntary product standard similar to organic certification - but in this case for recycled materials. GRS certification is administered by the Textile Exchange (a global non-profit) and is a holistic standard that verifies that a product really does have the recycled content it claims to have. Like GOTS, GRS also takes into account the full supply chain, addressing traceability, environmental principles, social requirements, chemical content and labelling.
