What is the GRS?

The Global Recycled Standard (GRS) is an international standard developed by Textile Exchange, a non-profit organisation that promotes sustainable practices in the textile industry. The GRS establishes requirements for the verification and certification of products manufactured with recycled content.

What does it include?

The GRS covers a wide range of materials, including polyamide (nylon) and polyester, as well as other textile materials. The standard focuses on the supply chain of products and establishes criteria to ensure the traceability and integrity of recycled content at each stage of the manufacturing process.

Minimum content

In terms of the minimum recycled content required by the GRS, the standard states that a product must contain at least 20% recycled material to be eligible for certification. This means that at least 20% of the weight of the product must come from recycled materials. This percentage refers to the total content of recycled material in the product, including both post-consumer recycled material and pre-consumer recycled material (production offcuts, factory surpluses, etc.).


It is important to note that the GRS also has additional requirements in terms of social and environmental practices in the supply chain, such as proper management of chemicals, compliance with labour standards, waste minimisation and traceability of recycled materials. These requirements aim to promote responsible and sustainable production in the textile industry.
