How do University of Bonn researchers filter microplastics?

Researchers at the University of Bonn developed a filter inspired by fish gills, which effectively captures over 99% of microplastics without clogging.

Can new washing machine filters stop microplastic pollution?

Yes, a new fish-inspired filter design shows promise in significantly reducing microplastic release from washing machines.

Why are fish gills effective at filtering water?

Fish gills have a natural funnel-shaped structure with comb-like elements that filter water and trap particles without getting clogged.

Fish Gills Inspire Microplastic Filter for Laundry

Microplastic pollution from laundry is a growing concern, with washing machines releasing substantial amounts of plastic fibers into wastewater annually. While current filters exist, they often prove inefficient or clog easily. Scientists have now turned to nature for a solution, drawing inspiration from the gill arch systems of fish like sardines.

These fish possess funnel-shaped gill structures that act as highly effective cross-flow filters, trapping plankton while allowing water to pass through. This natural design prevents clogging because filtered particles roll toward the throat. Researchers have successfully replicated this mechanism, creating a filter that separates over 99% of microplastics without becoming blocked.

While promising, the technology faces hurdles for widespread adoption, including potential washing machine modifications and user maintenance. However, the researchers emphasize the filter's low production cost and simple mechanics, hoping it will be integrated into future washing machines to combat microplastic release.
