Biomass Magazine, “Balancing Digester Diets” by Kate Fletcher
About twice the size of JC-Biomethane is Harvest Power’s 50,000-ton food waste community digester near Orlando, Florida. Some waste from Disney World is brought to the facility, including the Ritz-Carlton and JW Marriott hotels at Grande Lakes Orlando.
After contaminant removal in Harvest Power Florida’s low solids AD process, “the mix tank is used to mix some of the fat, oils and grease, food waste and the other types of materials and blend them together so you don’t send slugs of one heavy material over another into the digesters,” says Brandon Moffatt, senior vice president of energy for Harvest Power. “It’s trying to have the right mix and always trying to keep that in balance, so we’re continuing to optimize our recipe and make sure we have balanced feeding to make sure the system is stable.”
