Washing machine study on microplastics published

In one of our last studies on the topic of microplastics, we looked at typical everyday questions relating to washing. One question was: Are washing machines really a hotspot for microplastics? Another was: What can everyone do quickly and easily at home to reduce the input of microplastics from textiles? Answers can be found in the blog and in our publication.

Forever Chemicals – PFAS (Part 1)

Non-stick pans, waterproof clothing, food packaging – within all these products lie toxic “forever” chemicals called PFAS (per- and polyfluoroalkyl substances). These synthetic chemicals are used in various industries for their water-, stain- and grease-resistant properties, but contaminate the air, water, and soil along the entire value chain. They have been detected everywhere from human blood and organs, groundwater, marine animals, wildlife, rain, and remote regions of the Arctic. Because of their high persistence, they can take thousands of years to degrade and thus accumulate in the environment. Combined with their toxicity, high mobility, accumulation in organisms (bioaccumulation and -magnification), they are a major concern as environmental pollutants. The EU has recently released its proposal for a PFAS ban. In our two-part blog, we get to the bottom of the issue.

Washing Maschines as a Source of Microplastics?!

Washing synthetic textiles releases large amounts of microplastics into the environment every day worldwide. This is why France is introducing mandatory microplastic filters for new washing machines beginning in 2025. But just how effective are such filters? And is this the most effective approach moving forwards? This blog post covers how microplastics are formed during washing, which factors influence their formation, the reduction and prevention strategies which currently exist, and potential solutions.

New data on microplastic removal from wastewater

Wastewater treatment plants are important point sources of microplastics and micropollutants into the environment. Many wastewater treatment plants will be required to upgrade their facilities with an advanced treatment step to remove micropollutants, but these processes do not target microplastic removal. We therefore investigated the ability of two advanced treatment methods and our novel Wasser 3.0 PE-X® process to remove microplastics at the wastewater treatment plant in Landau, Germany. Read more about the key finding of our study, which was recently published open access in MDPI Water.

EU Urban Wastewater Treatment Directive

The EU directive on urban wastewater (Council Directive 91/271/EEC) is decisive for the control and prevention of pollution. Although it has led to improvements in water quality across Europe since its introduction in 1991, a lot of pollution is still not restricted or regulated, e.g. Micropollutants and microplastics. Therefore, at the end of 2022, the EU published a proposal for a revised directive on the treatment of urban wastewater. More about this in the blog.

Quick and efficient: PFAS analysis

Perfluorocarboxylic acids (PFCAs) are anthropogenic organic compounds with very unique and useful properties, e.g. surfactant properties and immense stability. These substances are nowadays widely used in many industrial and consumer products. Analytical methods show limitations, a new derivatization method could help.
