100 % compostable – Guarantee Mark ZERKOM®

100 % compostability based on binding test standards to ensure freedom from residues (no microplastic residues), soil compatibility, and complete degradation.

The "100 % compostable" guarantee mark labels products whose 100 % compostability has been independently tested and confirmed. It ensures that products are 100 % degraded after use without polluting the soil, environment, or the organisms living within it.

The mark is based on a binding guarantee mark statute, clearly defined test standards, independent testing procedures, and ongoing monitoring. This goes significantly beyond general environmental labeling or purely promotional statements.

Why companies need this guarantee mark

  1. Legally secure proof of 100 % compostability: The guarantee mark provides companies with clear, robust, and legally secure evidence. Testing covers not just the degradation process itself, but explicitly that products degrade completely and without residue, leaving no harmful substances in the soil. This ensures compliance with the Green Claims regulation, packaging and waste law, and competition law.
  2. Binding test standards instead of self-declarations: Use is only permitted after successful testing by the guarantee provider or recognized testing centers. Testing includes:
    • Biodegradability according to AS 5810
    • Terrestrial testing according to OECD 208 (soil compatibility)
    • Earthworm toxicity testing according to ASTM E 1676
    • Measurement of residue-free status (especially microplastics)
    • Material, ingredient, and spectral analyses
    • Testing of all components (printing inks, adhesives, coatings)
  3. 100 % compostability of all product components: The mark may only be used if every single component – including adhesives and material bonds – meets the requirements without exception. Products with problematic or environmentally harmful components are excluded.
  4. Monitoring, re-testing, and sanctions: The mark is subject to ongoing monitoring. Re-testing is mandatory in the event of material changes. Violations lead to the withdrawal of the certificate and sanctions, ensuring the permanent integrity of the seal.

Conclusion

The "100 % compostable" ZERKOM® guarantee mark stands for clearly tested, bindingly regulated, and traceably monitored 100 % compostability of products. It creates legal certainty, reduces greenwashing risks, and strengthens the trust of authorities, business partners, and consumers.
