Floating Trash-Eaters Clean Up Baltimore Harbor

Waterfront Partnership of Baltimore

Mr. Trash Wheel and Professor Trash Wheel, the solar- and hydro-powered trash interceptors cleaning up Baltimore’s inner harbor, have the ability to suck up plastic bags, Styrofoam containers, cigarette butts and other debris. The waste is burned to generate electricity, and plans exist to increase recycling capabilities in the future.
