Trellis Biomass Conversion ProjectHB

This project converts a manufacturing plant’s heating system to wood pellets, saving 1,350 tonnes of greenhouse gas emissions over 20 years. 

Carbon Project Type: Biomass
Location: East Templeton, Massachusetts, U.S.
Year: 2008-2009
Volume: 1,350 metric tonnes

The project facility consists of a block building, approximately 38,000 square feet, used for wood manufacturing. During the 2006-2007 heating season 30,400 square feet was in use.

For the heating season of 2008-2009, the owners expanded the heated area of the building by 6,600 square feet for additional office and manufacturing space. This would have required approximately an additional 1,200 gallons of fuel oil. As it existed, the structure was heated by a 950,000 BTU oil burner producing steam heat with one heating zone for the entire building. This used approximately 6,000 gallons of #2 fuel oil per year when maintaining temperatures of 49°F in the evening and 58°F during the day.

The biomass conversion created 14 zones with a new hot water distribution system employing a 1,140,000 BTU pellet boiler. This boiler can also be used to burn corn.

At project inception, it was estimated that a normal heating season would use approximately 26 tons of pellets. The oil burner was completely replaced and dismantled.

Sustainable Development Benefits

This project will reduce a total of 1,350 tonnes of greenhouse gas pollution, weather depending.

Project Participants

This project is a collaborative effort between Trellis Structures, Inc. and NativeEnergy.

Validation and Verification

The project owner provides auditable pellet purchase records at least annually. The carbon-reducing impact of the pellets burned is based on the assumed displacement of the amount of baseline fossil fuel use having an equivalent heating value to that of the pellets consumed.

Financial Additionality

This project met NativeEnergy’s stringent additionality criteria, as our funding was necessary to the project’s implementation.
