►INTRODUCTION TO GRS: GLOBAL RECYCLED STANDARD
GRS certification, the Global Recycled Standard, is an international, voluntary certification system. It mainly sets third-party certification requirements for products’ recycling content, chain of custody, social responsibility and environmental practices, and chemical restrictions. The goal of GRS certification is to promote the use of more recycled materials in products and reduce potential hazards during production.
● Recycling content: stipulates the proportion and type of recycled materials used in products.
● Chain of custody: ensure product tracking and verification throughout the entire process from raw materials to final products.
● Social responsibility and environmental practices: Supply chain manufacturers are required to comply with relevant social responsibility and environmental regulations.
● Chemical restrictions: Restrict the use of certain harmful chemicals in products.
GRS certification was originally developed for the needs of the textile industry to check recycled products or the use of recycled materials in certain specific products. With the increasingly serious global environmental problems and the increasing shortage of resources, the importance of GRS certification has gradually increased. Many national governments and companies have begun to pay attention to the importance of environmental recycling and reuse. Companies certified by GRS can prove that their products comply with global recycled standard, thereby gaining more recognition and competitive advantages in the market.
