Sustainable foam can remove 99.9% of microplastics

Microplastic pollution is a serious threat to our environment. Researchers have responded by creating a foam from cellulose and chitin that effectively removes microplastics from water with up to 99.9% efficiency. The foam is made from abundant, sustainable materials and maintains its effectiveness after repeated use. This breakthrough could provide a practical and environmentally friendly way to clean up microplastic pollution in both terrestrial and aquatic environments. Initial tests have been incredibly promising, showing high removal rates in real-world water samples.
