About Mr. Trash Wheel
Baltimore found a way to make pollution control look like a gigantic hungry cartoon character. At the mouth of Jones Falls, two enormous googly eyes stare over a conveyor belt while a fourteen-foot water wheel turns beside them. This is Mr. Trash Wheel, a machine whose job is to eat the garbage flowing toward the harbor.
Environmental scientist and shipbuilder John Kellett developed the system after watching litter move down Jones Falls toward the Inner Harbor. The first trash interceptor of its kind was commissioned by the Waterfront Partnership of Baltimore and installed in May 2014. Floating booms guide debris toward the machine. Rakes lift the material onto a slow conveyor, and the belt carries it into a dumpster mounted on a separate barge.
The machinery uses both the river and the sun. Flowing water turns the wheel whenever conditions allow. When the current is too weak, solar panels power pumps that move water onto the wheel and keep the conveyor operating. The system can handle ordinary bottles and food containers along with tires, mattresses, branches, and other objects that have no business floating into the harbor.
The giant eyes and name came later, turning useful infrastructure into a Baltimore celebrity. Mr. Trash Wheel now has a family of related interceptors around the harbor, each with a name and personality. The original remains at Jones Falls, quietly performing the serious job underneath the joke: waiting for the city’s trash to arrive, swallowing it, and dumping it into a dumpster.
