Third update of the well-known poster showing biodegradable polymers in different environments according to established standards and certification schemes.

The expert group met again this year to discuss the latest scientific evidence in the field of biodegradable polymers in order to make meaningful changes to the poster. The generic classification on the poster is only supported by tests performed in the context of certification. Therefore, the expert group decided to include the biodegradability of polycaprolactone (PCL) in additional environments: soil, freshwater, marine and anaerobic conditions. In addition, a new certification for marine biodegradability has been published by DIN CERTCO in 2023, based on ISO 22403, the standard that provides requirements for marine biodegradability, and is now mentioned on the poster. A new poster design and a more precise definition of biodegradation and biodegradability complete the update for this year.
