Global Recycled Standard (GRS): What You Need To Know

The development and utilization of nature by human beings have never stopped. With the deepening of the understanding of nature, human beings gradually realize the importance of protecting the environment while developing and utilizing the environment, so many regulations and certifications have been formulated.

Today, let’s take a look at Global Recycled Standard certification.

What is Global Recycled Standard (GRS)?

The Global Recycled Standard (GRS) is an international, voluntary, full-product standard that sets requirements for third-party certification of recycled input, chain of custody, social and environmental practices, and chemical restrictions.

The primary goal of the GRS is to increase the use of recycled materials in products and reduce the harmful social, environmental, and chemical impacts of production.

Who invented Global Recycled Standard (GRS)?

The Global Recycling Standard (GRS) was originally invented by Control Union Certifications in 2008 and ownership was transferred to Textile Exchange on January 1, 2011.

Textile Exchange is a global not-for-profit organization driving positive action on climate change in the fashion and textile industries.

What is the newest version of Global Recycled Standard?

After a multi-stakeholder review, the latest version 4.0 of the Global Recycling Standard was published on 1 July 2017.

Based on the news from Textile Exchange, after a comprehensive multi-stakeholder review, a new standard system may be released in Q4 of 2023 (subject to change).

What are Global Recycled Standard requirements?

If you want to be certified by the Global Recycled Standard, you can apply to an accredited certification body after meeting the following conditions, which will make your work easier and save costs.

  • Claimed Material accepted for the standard meets the established definition of Recycled Material.
  • Products with 20% or more recycled content.
  • Claimed Recycled Material follows a complete, verified chain of custody from input to final product.
  • Workers employed at facilities involved in the production of GRS products are protected by a strong social responsibility policy.
  • Facilities involved in the production of GRS products have strong environmental protections in place.
  • Chemicals used in the production of GRS products do not introduce unnecessary harm to the environment or workers.

What products does the Global Recycled Standard apply to?

Global Recycled Standard is for finished or intermediate products based on recycled materials, such as:

  • recycled garments, clothes, and final textile products
  • recycled home textiles
  • recycled fabrics
  • recycled yarns

Why is GRS important?

  • Define “recycled material” and verify recycled content in products.
  • Provide greener and more informed purchasing decision-making solutions for brands and consumers.
  • Reduce the harmful impact of production on people and the planet.
  • Ensuring that products are processed in a more climate-friendly manner.
  • Encourage a higher percentage of recycled content in products.
