At Naeco Fibers, we have obtained the Global Recycled Standard (GRS) certification, the leading international standard for verifying recycled content and ensuring traceability throughout the entire supply chain.
The GRS certification, managed by Textile Exchange, certifies that the recycled materials we use are fully traceable from their origin to the final product. In addition, it validates that our manufacturing process complies with strict environmental, social, and chemical control requirements.
A new step forward for the circular economy
With this certification, we are taking another step forward in our commitment to responsible, transparent production aligned with the principles of the circular economy.
Obtaining the GRS certification is a recognition of our business model based on traceability, quality, and environmental commitment. Not only do we manufacture 100% recycled fibers, but we can now also certify it with an internationally recognized standard.

Quality and traceability for demanding industries
The GRS certification complements the OEKO-TEX Standard 100 certification obtained in 2025, further strengthening our position as a manufacturer of sustainable, high-quality fibers.
Since our launch, we have specialized in the production of black recycled polyester fibers for the automotive industry, one of the most demanding industrial sectors in terms of technical and environmental standards.
Our factory features a long, two-stage production line, a technology that allows us to manufacture fibers with high-quality standards tailored to the needs of highly specialized industries.
A benchmark in recycled polyester fibers
With this new recognition, at Naeco Fibers we continue working to strengthen our position as a supplier of sustainable recycled polyester fibers, actively contributing to reducing environmental impact and promoting a more circular industry.
