Sewage treatment plant

The project aimed to make a significant, transdisciplinary contribution to applied research on the prevention of plastic discharges into water bodies via drainage systems from a behavioural and environmental economics perspective.

This project determined sources and sinks of microplastic in the Warnow river basin, as well as relevant dissemination processes on its way to the open Baltic Sea. Separate models were linked so that the resulting model covers the entire river basin including estuary and coastal waters.

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.

Within the framework of this project,  a first-ever accounting of macro-, meso- and microplastics released into the German part of the Danube river basin was achieved, with measuring stations at its main tributaries. Microplastic particles (particles < 5 mm) were examined by using various, complementary analytical methods.

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 REPLAWA project covered questions of water resource protection in connection with wastewater treatment. The project investigated and quantitatively assessed entry points into water bodies through treatment plants, storm water drainage, and combined sewer overflows as well as swales at treatment facilities and in sewage sludge.
