We assess the mass degradation in % of the test sample after a defined period of time as well as the ecotoxicological safety.
Criteria for awarding the label
- Only for 100 % natural fibres and 100 % materials of natural origin
- Confirmed degradation of at least 90 % (mass loss) after 12 months
- Passing of the ecotoxicity tests
- Valid only for the tested quality (construction/weight/colour)
