Polymer analysis

In PLAWES, the modelling system of the German national park Weser-Wadden Sea was the first large European river basin that was investigated in detail regarding its microplastic pollution.

The spread of microplastics in rivers showed that along a given waterway there are sources as well as sinks. Thus, dams and reservoirs constitute important but until now hardly investigated parts of a water system that serve as examples for risk vs. usefulness of sedimentation of microplastics.

This project systematically detected emissions of plastics into wastewater from relevant industries. Emissions levels were analysed along all points of the value chain (production, transport, processing, and cleaning of synthetic materials).

The aim of the project was to develop concepts and preliminary planning for the implementation of an infrastructure for the collection, ship-based treatment, and marketing of plastic waste in order to reduce the input of plastic waste into the environment and marine ecosystems. The project's target regions were primarily less developed countries in the Global South.

As part of the revolPET project, a solvolytic recycling process for waste PET plastics (Polyethylene Terephthalate) from multilayer and other mixed materials was elaborated and experimentally tested.
