If you are searching for new materials for your eco-designed products Refashion recommends the Textile Exchange Preferred Fiber & Materials Report [Link 1] which identifies solutions to avoid the use of standard materials.
For sourcing biological materials, look at the list of GOTS standard-approved suppliers [Link2].
For sourcing recycled materials, look at the list of GRS (Global Recycle Standard) or RCS (Recycled Claim Standard) certified suppliers. [Link 3]
The Refashion “Eco design” platform also has numerous resources to assist in choosing the materials for your eco-design project. All you need to do is register. [Link 4]
