Story summary

Researchers at the University of Bonn have developed a patent-pending filter for washing machine wastewater.
The filter removes over 99% of plastic fibers and is inspired by fish gill systems.
Current washing machines produce up to 500 grams of microplastics annually from textile abrasion.
The Federal Ministry of Research and the European Research Council support the project, which aims to integrate the filter into future machines.
