NYC expands food waste-to-energy pilot

New York City is planning an expansion of its anaerobic digester pilot program launched last summer at the Newton Creek Wastewater Treatment Plant in Greenpoint.

The purpose of the one-year pilot was to test the logistics of source separating food waste, collection of the waste, preprocessing by Waste Management and injection into the wastewater treatment plant digesters, said Anthony Fiore, director of New York City’s Department of Environmental Protection Office of Energy.

From April 2013 to May 2014, the facility processed between 1.5 and 2 tons of source separate organic waste (SSO) a day. This winter, the project will be scaled up over a three-year period beginning at 50 tons per day to 250 tons per day. “This volume of SSO will allow us to better understand the ability to source separate waste from both residential and commercial sectors, the efficiency of processing the material into a consistent bioslurry and the costs and benefits of treating food waste in anaerobic digesters,” Fiore said.
