GRS stands for Global Recycled Standards. GRS is a tracking system to track the transactions of said material from its raw shape to final or consumer form. It covers the complete chain of GRS certified goods. GRS intends to verify the recycled contents of a good or product. GRS certification is very common in textile sector where fiber is made from the used plastic bottles and other items. First of all GRS fiber is made and then it is sold to spinning mills with GRS certificate and its transaction. After that this GRS certified yarn is used to make fabric and garments. At every stage the seller and buyer ensure the GRS transaction.
