Sewage sludge

Analysis of Microplastics - Sampling, preparation and detection methods

This status report was prepared within the framework of the cross-cutting topic 1 "Analytics and reference materials" of the research focus. It summarizes the contents of the project discussions and coordination within the cross-cutting issue. The organization of this ongoing process of development or elaboration has been supported by several events.

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.

InRePlast

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.

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 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.

PLAWES

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.

REPLAWA

Reduction of the Input of Plastics via Wastewater into the Aquatic Environment
January 2018
December 2021

The REPLAWA project covers questions of water resource protection in connection with wastewater treatment. The project will investigate and quantitatively assess 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.

PLASTRAT

Strategies for Reducing the Entry of Urban Plastics into Limnic Systems
September 2017
December 2020

The common element of all investigations in PLASTRAT is the development of solution strategies for sustainable limitation of the spread of plastic residues in the aquatic environment on technical, environmental, scientific and social-ecological levels. The objective consists of developing a multi-criteria evaluation approach for the environmental compatibility of different types of plastics.
