A unique Gas to energy (G2E) system at the F. Wayne Hill Water resources Center (Hill WRC) in Buford, Georgia uses by products of the wastewater treatment process to reduce operating costs and sanity sewer overflows. The Hill WRC produces methane gas by digesting biosolids from wastewater along with fats, oils, and grease (FOG) from area restaurants and other high-strength industrial wastes (HSW) to produce financially viable results. This low British Thermal Unit (BTU) digester gas generates just over two megawatts of electric power (enough for 1,500 homes) and provides process heat by recovering more than seven million BTUs of heat. This can supply up to 40 percent of the entire plant’s power needs in addition to all of the heat needed for the anaerobic digesters.
