Recycled materials in

Recycled materials are difficult to certify. With their previous life, recycled materials are posing different challenges than regular virgin material. Therefore within the OEKO-TEX® STANDARD 100 framework these materials are treated differently.  

For the certification of recycled materials with OEKO-TEX® STANDARD 100 different rules apply as for regular materials. If recycled is mentioned in the article scope the following basic rules apply: 

  1. At least 20% of the main textile material needs to be recycled 
  2. More information about the source of the materials is requested in the application 
  3. An effective quality management system needs to be proven. This is needed to ensure a consistent product quality.
  4. The testing program can differ compared to virgin material. While there is no chemical test whether a material is recycled or not, the varying source can lead to a higher testing frequency.  
  5. A separate certificate from a virgin material is needed.  
  6. Blends with virgin materials are allowed when they are necessary for the manufacturing of the material.
