GRS certification, which stands for Global Recycled Standard certification, is a comprehensive and internationally recognized standard that sets requirements for third-party certification of recycled content, chain of custody, social and environmental practices, and chemical restrictions. The GRS certification is designed to verify the recycled content in products and to provide assurance to consumers that the materials used in the products have been responsibly sourced and processed. It covers the full supply chain from the source to the final product and ensures that the materials used are both environmentally and socially responsible. GRS certification is widely used in the textile industry, but it can also be applied to other industries that utilize recycled materials. This certification plays a crucial role in promoting sustainability and transparency in the global supply chain, and it is a valuable tool for businesses and consumers seeking to make more informed and responsible choices.
