The Potawatomi casino recently installed a nonsewered food waste recycling system called Grind2Energy, made by InSinkErator, a business unit of Emerson. Annual generation is about 180 tons/year. About 3.5 tons/week of preconsumer food waste from the casino’s two largest kitchens - the production kitchen and the buffet kitchen - are being captured, according to executive chef Peter Gebauer. The casino is located across the parking lot from the Forest County Potawatomi Community’s new food waste biodigester facility, which started up last year and can generate up to 2 MW of electricity.

Downtown Milwaukee is close by, just north of the property (not shown in photo).

It is located on a former brownfield on the western edge of the Potawatomi Bingo Casino’s property (see casino #2). The anaerobic digestion facility (#1 and bottom photo) has two 1.3 million gallon reactors, sized for 30-day hydraulic retention.
