Polymers in the underground: on the biodegradation of synthetic polyesters in soils
"Biodegradable plastics have been heavily used in agricultural applications for years, while the biodegradation of these materials in soils remained poorly understood on a fundamental level. This contribution will present highlights on our past and ongoing work on the key steps involved in polyester biodegradation in soils: microbial polymer surface colonisation, polyester hydrolysis by extracellular microbial esterases, and the microbial utilisation of polyester hydrolysis products. The talk will also summarise remaining knowledge gaps on polyester biodegradation in soils and present some ideas of how these can be addressed."

Towards non-persistent polyethylene-like materials by polymerization catalysis methods
Polyethylene is the most important plastic with excellent materials properties due to its crystallinity, yet it is persistent in a natural environment. We pursue approaches to endow polyethylene-like materials with a non-persistent nature by introducing low densities of functional groups as break points in the chain. Key are polymerization catalysis methods that are compatible with such functional groups. These also provide access to unique polymer micro- and nanoparticles for studies of the fate of microplastics in the environment.

Microbial Degradation of Plastics: Searching the Needle in the Haystack
"Bacteria as plastic waste disposal? Will microorganisms be able to eat microplastics in the future and thus remove them from the environment? What is behind the microorganisms, what effect they have and what opportunities there are for the reduction of nano- and microplastics will be explained here. Further I will address our latest attempts to identify plastic-degrading enzymes and bacteria by mining global metagenomes."
