Mr Trash Wheel, Garbage Gobbler powered by river

BALTIMORE’S HARBOR IS cleaner than it has been in decades thanks to two anthropomorphic trash wheels pulling debris from its waters.

Mr. Trash Wheel and Professor Trash Wheel, the latter of which was installed in December, are solar- and hydro-powered trash interceptors based in Baltimore’s Inner Harbor, clearing debris before it enters the Chesapeake Bay. Over a million pounds of trash has been pulled out of the water by Mr. Trash Wheel since it was installed in May 2014.

The contraption works by drawing power from solar panels and the current of Jones Falls River to turn a waterwheel, which in turn powers a conveyer belt. Containment booms direct the trash towards the conveyer belt, which then drops the debris into a waiting Dumpster. That bin sits on its own platform and can be floated out when it’s time to change it.

Kellett keeps track of the garbage pulled out of the water. The haul includes almost nine million cigarette butts and over 300,000 plastic bags. The data is used to support environmental legislation. For example, the Waterfront Partnership recently supported a bill that would ban Styrofoam containers. Mr. Trash Wheel picks up an average of 14,000 Styrofoam containers a month, second only to cigarettes.
