Spruce Haven Farm Anaerobic Digester Is Operational
New York State Energy Research and Development Authority (NYSERDA), Grant Program
Spruce Haven Farm

The anaerobic digester located at Spruce Haven Farm dairy, owned and operated by Doug Young, began producing biogas in early September.  By October 1st the digester had been brought up to an operating temperature of 100 degrees Fahrenheit, enabling the  anaerobic digestion of manure from the 3,360 animal herd to create  enough biogas to operate a Combined Heat and Power (CHG) system capable of producing 502kW.  The system is currently running at approximately 95% capacity, producing 480kW of renewable electricity.

The facility was designed and constructed with oversight by Larsen Engineer’s staff.  The project is funded through a NYSERDA grant program. Pictured below is the inflatable flexible membrane cover which collects the biogas produced in the 1.5 million gallon lined lagoon.  To discuss the feasibility of an aerobic digester at your farm or facility please contact Scott Fonte, P.E. of Larsen Engineers at .

Larsen was successful in obtaining 90% funding under the stimulus package energy conservation grants for sustainable green planning. A total of 294 applications were submitted for the Grant Program with only 54 awards being made. Larsen Engineers prepared the state grant application, the green infrastructure design and coordinated construction. Green Infrastructure projects include a rainwater harvesting system and installation of a green roof. Energy efficient improvements, include installation of energy efficient lighting, solar units which will provide almost 20% of the facility’s current electric needs; and a new 93.3% efficient boiler.
