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.

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.

Plastics in the environment are an increasingly serious challenge. As macroplastics deteriorate, such as through tire abrasion, the resulting microplastics can enter the aquatic environment through a variety of entry points. As vehicle traffic increases, there is an inevitable increase in microplastics from worn tires ending up in the environment.
