Potawatomi Food Waste to Energy Project

The Forest County Potawatomi’s food waste-to-energy project began generating electricity in Menomonee River Valley of Milwaukee in October.  The $20 million project produces biogas in two 1.3 million-gallon tanks from food waste turned into liquid organic feedstock for microorganisms.  The microorganisms breakdown the feedstock which produces biogas that is used as fuel for electricity generation.  The project uses two GE engine generators built in Waukesha, WI and has a capacity of 2 megawatts—enough to power approximately 1,500 homes.    The plant can also capture waste heat from biogas production and supply hot water and heat.  Some of the food waste comes from local bakeries, cheese plants, and a soy production facility.  This Potawatomi project received $2.6 million in funding from the U.S. Department of Energy and a grant from Wisconsin’s Focus on Energy program.
