A reusable and biodegradable fibrous foam developed by researchers at Wuhan University in China can remove up to 99.8% of microplastics from polluted water.
The foam is made from a self-assembled network of chitin and cellulose obtained from biomass wastes.
The foam has been successfully field-tested in four natural aquatic environments and can adsorb various types of microplastics, even in polluted water with toxic metals and chemicals.
Researchers believe that the foam, made from readily available raw materials, has great potential for large-scale production and can help address the growing microplastic problem.
