GRS is recognized as the most important international standard for the sustainable production of garments and textile products made from recycled materials.
Global Recycle Standard certifies products obtained from recycled materials and manufacturing activities.
It enhances products made with recycled materials, in compliance with environmental and social criteria extended to all stages of the production chain.

It is promoted by Textile Exchange, one of the most important non-profit organizations promoting responsible and sustainable development in the textile sector at an international level.

With this standard, Textile Exchange recognizes the fundamental importance of recycling for the growth of a sustainable production and consumption model; aims to favor the reduction of the consumption of resources (virgin raw materials, water and energy) and to increase the quality of recycled products.

The GRS provides for the release of an environmental declaration verified by a third party that proves:
- The content of recycled materials of their products (both intermediate and finished)
- Compliance with environmental and social criteria in all of the production chain.
All products that are composed of at least 20% pre-consumer and post-consumer recycled materials can be GRS certified.

The GRS criteria extend to the following areas:
- Composition of the product and content of recycled materials
- Maintaining traceability throughout the entire production process
- Restrictions on the use of chemicals.
- Compliance with environmental criteria
