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.

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.
