2 teens won $50,000 for inventing a device that can filter toxic microplastics from water [View all]


Two teenagers from Woodlands, Texas invented a device that could help address one of the most pervasive and challenging forms of pollution on Earth: microplastics.


Huang and Ou's device is remarkably small, about the size of a pen. It's essentially a long tube with two stations of electric transducers that use ultrasound to act as a two-step filter.

As water flows through the device, the ultrasound waves generate pressure, which pushes microplastics back while allowing the water to continue flowing forward, Ou explained. What comes out the other end is clean, microplastic-free water.

The two teens tested their device on three common types of microplastics: polyurethane, polystyrene, and polyethylene. In a single pass, their device can remove between 84% and 94% of microplastics in water, according to a press release.
