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 7.1: Microplastics around dams - How do plastic particles behave in reservoirs?

Plastic is now ubiquitous not only in the sea but also in many inland waters. In certain areas, such as at barrages or in dams, the flow velocity decreases. As a result, the particles previously held in suspension by the current begin to sink to the bottom of the water and can then accumulate in the sediment.

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.

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

The project aims 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.

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

This project determines 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 will be 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 is the first large European river basin that is investigated in detail regarding its microplastic pollution to.

Ship-Based Treatment of Plastics for the Implementation of Value Chains in Less Developed Countries as well as for the Prevention of Plastic Inputs into the Environment and Especially in Marine Ecosystems
August 2017
December 2019

Since it is technically and economically impossible to reduce the amount of plastic waste in oceans, solutions to cut the entry of such substances into the environment must be developed. Developing countries, however, often lack land-based approaches to such solutions.

Tyre Wear in the Environment
August 2017
January 2021

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.
