Magnetic Powders Tackle Microplastic Pollution in Water

In October 2025, researchers from the Durban University of Technology have unveiled a groundbreaking solution to the growing problem of microplastic pollution in water. They have developed specialized "magnetic cleaning powders" that can effectively remove up to 96% of small microplastic particles from water samples, including drinking water and municipal wastewater.

The powders work by attracting and attaching to the microplastics, forming clumps that can then be easily extracted using a strong magnet. This innovative approach has proven successful not only in laboratory conditions but also in real-world water samples, making it a practical and scalable solution.

Notably, the powders are particularly effective at capturing the smallest microplastics, which are the most harmful to health and the environment. Unlike many existing filters, these magnetic nanocomposites can efficiently remove even the tiniest plastic particles from the water. The researchers are now focused on scaling up the method and designing simple, affordable devices that can be adopted by households and water treatment plants.

This breakthrough offers a promising path to clean water and protect ecosystems from the growing threat of microplastic pollution, which has been found in tap water, fish, and even the air we breathe. With their cost-effective and environmentally friendly approach, the researchers hope to make a real difference, especially in resource-limited settings where advanced filtration systems are often impractical.
