Magnets could be used to remove plastic particles

Environmental pollution caused by microplastics and nanoplastics is a ubiquitous problem which cannot be tackled using currently available cleaning concepts. Researchers at FAU have now demonstrated how magnets could be used to remove plastic particles of various types and sizes from water.
