"GRS Certified", or Global Recycled Standard, is a voluntary, third-party certification that verifies the recycled content of products and also ensures that social and environmental standards are met throughout the production process. The Textile Exchange developed the standard to verify the percentage of recycled materials in a product and to ensure responsible environmental and social practices, including worker safety, fair wages, and chemical restrictions. GRS certification provides traceability and transparency in the supply chain from the waste stream to the finished product.
