Microplastic-Capturing Magnetic Powders

The challenge is enormous

Researchers at Australia's RMIT University have developed a magnetic powder that may have huge implications for cleaning up the seas and oceans. The team is led by chemical engineering professor Nicky Eshtiaghi.

The magnetic powder itself is made out of recycled waste and its expertly designed nano-sized structure has the capability of capturing invisible plastic—that is, microplastic which can be less than one micrometer wide "or 1,000 times finer than human hair." In addition, the magnetic powder can also absorb other pollutants, making it an invaluable tool for waste management.

Having huge implications for wastewater treatment plants and the like, the RMIT University researchers are currently looking for industrial partners to help them scale up the technology.
