Persistence Polymers

The study of biodegradation of polymers and microplastics in environmental compartments such as soil, sediments of water is important for the regulatory ssessment of the persistency of these compounds in the environment.

Fraunhofer IME has an extensive experience in performance of environmental simulation studies on the biodegradation and fate of polymers. Our focus in these activities is on the adaption and modification of the applied test protocols for the specific challenges associated with the testing of polymers, e.g. defining new polymer-specific endpoints for regulatory assessment of biodegradation beyond mineralization.

We offer standard and specifically adapted studies on the degradation of polymers in soil, water/sediment systems, water or waste water treatment simulations in accordance with current test guidelines (e.g. OECD TG 307, 308, 309, 314B). For these purposes, we are using in-house synthesized radiolabeled polymers in cooperation with Fraunhofer IAP, as these materials are generally not commercially available. In addition, state-of-the art instrumentation for polymer and plastics analysis and characterization is available to support this research.
