Global Recycled Standard is a standard that checks the use of recycled ingredients in textile products. Certifying that the recycled ingredient of the products and the social, environmental and chemical practices in the production are inspected, the GRS certificate defines the requirements for good working conditions and to minimize harmful environmental and chemical effects.

It aims to encourage a responsible and sustainable production and consumption model in the textile industry and to increase the quality of recycled products by developing products made with recycled materials in accordance with environmental and social criteria spread across all stages of the production chain.

In order for products to be GRS certified, they must contain at least 20% pre-and post-consumption recycled material.
