A recent study found an alarmingly high percentage of tap water has microscopic plastic fibers. In the United States, 94% of drinking water sample contained micro plastics; worldwide, 83%. The particles are so small, most filters can’t catch them: micro plastics may even cross human digestive tracts to enter organs. Could filters lead the way? Wole Soboyejo and team designed a new microporous and nanoporous water filter. Askwar Hilonga, winner of the Africa Innovation Prize, Royal Academy of Engineering, also designed a water filter based on nanotechnology. With increasing bans on plastic straws, innovation markets may open to new kinds of straws. Now is a good time for innovation. Submit your design for a personal straw – with filter.
