The world’s leading poster on biodegradability has been updated by the nova team of experts: current standards and certifications as well as the latest scientific findings
Hürth, 22 August 2024: The biodegradation of a material is a process that depends on the complex biological conditions at each site. In addition, only a handful of polymers have the inherent ability to biodegrade in different environments. Therefore, specific standards and certificates have been developed in recent years to provide a framework for declaring whether or not a product can biodegrade in an environment. Scientific verification and certification of the communication of environmental claims is becoming increasingly important under the Green Claims Directive. Biodegradability is one environmental claim that will need to be verified by third party certification.
In order to improve the understanding of biodegradation and biodegradability and their certification, a group of experts came together a few years ago to develop a poster showing which polymers biodegrade in which environments according to established standards and certification schemes. This group includes experts from the nova Institute (Germany) together with a number of leading experts from Normec OWS (Belgium), Hydra Marine Science (Italy/Germany), IKT Stuttgart (Germany), Wageningen University & Research (The Netherlands) and in cooperation with DIN CERTCO (Germany) and TÜV AUSTRIA (Austria/Belgium).
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.
