What Is GRS (Global Recycled Standard)?

GRS is a product standard managed by Textile Exchange and used to verify recycled content in the textile, plastic, metal and paper sectors. The standard covers raw material origin, traceability throughout the supply chain and social and environmental production practices.

To carry GRS certification a product must meet the minimum 20% recycled content threshold. Sesli Tekstil achieves recycled content levels significantly above this threshold in its regenerated cotton yarn production.

Note: GRS does not certify how much recycled content a product contains, but rather that this content is genuinely recycled and documented across the entire supply chain. It's important not to confuse the two.

How Does GRS Supply-Chain Auditing Work?

GRS certification requires not a single product group but every layer of the supply chain to be separately certified. These layers are:

  1. Raw material collector / recycling facility: The stage where PET bottles or textile waste are collected and processed. GRS auditing starts at this point.
  2. Yarn manufacturer: The facility producing fibre and yarn from recycled raw material. Sesli Tekstil's suppliers are within the GRS scope at this stage.
  3. Fabric / product manufacturer: The Sesli Tekstil factory. A Transaction Certificate (TC) is issued for each production batch.
  4. Exporter / brand: The company that sells or exports the finished product. TC documents are passed on to the buyer.

Regenerated Cotton Yarn: GRS Use at Sesli Tekstil

Sesli Tekstil's GRS certification is focused on its regenerated cotton yarn production line. Regenerated cotton fibre — recovered through mechanical recycling from textile waste and cotton production scraps — is spun back into yarn and offered within our yarn category. This yarn is also used as a blend component in our blanket and pique production.

Environmental Contribution: From Waste Back to Value

Compared with virgin cotton production, regenerated cotton yarn offers clear advantages:

  • Water savings: While 1 kg of virgin cotton requires roughly 10,000 litres of water, regenerated cotton fibre uses only a small fraction of that volume.
  • Raw-material circularity: Textile waste and production scraps are returned to value and brought back into the production line instead of going to landfill.
  • Energy consumption: Significantly less energy is required compared with virgin fibre production.
  • Carbon emissions: The carbon footprint of raw-material farming, transport and processing is reduced.

Sesli Tekstil's circular approach: Producing from Uşak since 1967, our brand places regenerated cotton yarn at the centre of its sustainability vision. This approach delivers both raw-material cost stability and a meaningful contribution to environmental targets.

GRS Verification for Buyers: The Right Questions to Ask

With the EU Textile Sustainability Strategy and rising ESG reporting obligations for buyers, demand for GRS-certified products is growing rapidly. Buyers working with Sesli Tekstil can request the following documents:

  • Scope Certificate (SC): Lists the product categories at our factory under GRS scope.
  • Transaction Certificate (TC): Issued for each order, verifying that the product was manufactured under GRS scope.
  • Supplier SCs: The GRS certificates of our raw material and yarn suppliers.
Note: GRS documents can be verified in Textile Exchange's public database (textileexchange.org). Sesli Tekstil shares certificate numbers on request.

Frequently Asked Questions

What does GRS certification mean?
GRS (Global Recycled Standard) verifies that recycled raw material in textile and other products is tracked and documented by independent auditors from raw material to finished product. GRS certification can be obtained for a minimum of 20% recycled content.
What is the difference between GRS and Oeko-Tex?
GRS verifies the source and traceability of recycled content (supply-chain traceability). Oeko-Tex Standard 100 tests that the finished product is free of harmful substances (chemical safety). The two complement each other; Sesli Tekstil carries both on selected products.
Which Sesli Tekstil products are GRS-certified?
Sesli Tekstil applies GRS certification to its regenerated cotton yarn production. Regenerated cotton yarn — recovered from textile waste and cotton production scraps — is manufactured under GRS scope and can be supplied with this verification upon request.
