Story summary

Researchers found that magnetic cleaning powders, known as magnetic nanocomposites, can remove up to 96% of small polyethylene and 94% of microplastics from South African tap water.
The method is environmentally friendly and could be integrated into household water systems.
While effective for small plastics, the powders are less successful at removing larger particles.
The reusable and cost-effective nature of these powders presents a promising solution for global microplastic pollution.
