Factsheet 11: Microplastics in wastewater treatment - Development of sampling and analysis methods for detection of input quantities into surface waters

It is not easy to determine how much microplastic is contained in wastewater and sewage sludge. In addition to plastic, countless other particles and substances are present. To reliably determine the concentration of microplastic particles, complex procedures for sampling as well as for removal of foreign substances and analysis of the microplastic particles are required.

Factsheet 5.1: Removing microplastics from industrial wastewater - Process improvements through the use of flocculants

Microplastics can enter our wastewater along the entire value chain. Removal options exist primarily in wastewater treatment plants, here in the form of filtration, flotation and sedimentation processes. The removal performance of wastewater treatment plants determines how much microplastic is discharged into the environment.

Factsheet 2: Valuable waste plastic - Floating recycling plant recovers plastics before they enter the sea

In this factsheet, joint project KuWert shows how plastic recycling can be profitable. The research team developed a floating recycling platform, mobile and independent of local structures. The system was tested in coastal cities in West Africa, where a lot of plastic ends up in the sea.

Environmental Policy Instruments to Reduce Plastic Pollution of Inland Waters through Drainage Systems
January 2019
December 2021

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.

MicroCatch_Balt

Investigation of Sinks and Sources of Microplastics from a Typical Catchment Area to the Open Baltic Sea
August 2017
April 2021

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.

Microplastic Contamination in the Weser- Wadden Sea – National Park Model System: an Ecosystem-Wide Approach
September 2017
April 2021

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.

MicBin

Microplastics in Inland Waters – Investigation and Modeling of Entries and Whereabouts in the Danube Area as a Basis for Action Planning
October 2017
March 2021

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.
