Impact
Approximately 3,650 tons of manure and 36,500 tons of food and beverage waste are combined annually in the Haverhill anaerobic digester. Methanogenic bacteria break down the manure and organics to produce biogas which powers a 1 MW engine to produce renewable electricity. The digestate material byproduct of the process is a highly potent, low-carbon liquid fertilizer used by the farm to reduce commercial chemical fertilizer use and increase crop yields.
The engine powered by the biogas produced in the Farm Powered anaerobic digester generates more than 8,000 MWh per year of renewable energy, which is provided via net metering credits to the City of Haverhill’s schools and public facilities.
