DIN CERTCO
DIN CERTCO, TÜV Rheinland, is an independent certification body in the bioplastics market.
DIN CERTCO is a global leader in validating the compostability and biodegradability of materials. In an increasingly stringent regulatory environment, holding this certification mark represents the gold standard for demonstrating compliance with circular economy requirements.
What labels does DIN CERTCO grant and what do they mean?
Certification is not a single, uniform process; rather, it is adapted to the end-of-life environment of the product. DIN CERTCO has recognised the laboratories of AIMPLAS to carry out the tests that enable companies to obtain these certifications:
- DIN Industrial Compostable: Certifies that the material degrades in industrial composting plants (standard EN 13432).
- DIN Home Compostable: Ensures that the material degrades under home composting conditions, where temperatures are lower.
- DIN Biodegradable in Soil: Specific to agricultural products (such as mulch films) that must integrate into the soil without leaving microplastics.
- Biowaste Bags DINplus: A certification specifically designed for organic waste bags, ensuring optimal compostability.

DIN CERTCO Certification process: step by step
