University uses landfill gas as its primary energy

The University of New Hampshire (UNH), in cooperation with Waste Management of New Hampshire, Inc., has launched EcoLine, a landfill gas project that will pipe enriched and purified gas from Waste Management's landfill in Rochester to the Durham campus. UNH is the first university in the nation to undertake a project of this magnitude.

The renewable, carbon-neutral landfill gas, from Waste Management's Turnkey Recycling and Environmental Enterprise (TREE) facility in Rochester, New Hampshire, will replace commercial natural gas as the primary fuel in UNH's cogeneration plant, enabling UNH to receive 80-85 percent of its energy from a renewable source.

“By reducing the university's dependence on fossil fuels and reducing our greenhouse gas emissions, EcoLine is an environmentally and fiscally responsible initiative," said UNH President Mark Huddleston.

Construction is set to begin immediately on a landfill gas processing plant in Rochester which will purify the gas, and the 12.7 mile underground pipeline which will transport the gas from the plant to the university's Durham campus. UNH is expected to fuel its cogeneration plant with landfill gas by the fall of 2008. Estimated cost of the project, including the construction of a second generator at UNH, is $45 million.

As the nation's largest owner and operator of landfills, Waste Management recently announced a major landfill gas-to-energy initiative that will result in the creation of an additional 60 renewable energy facilities.

Waste Management currently has two landfill gas-to-electric plants at TREE producing green power for over 9,000 homes which will continue to operate, while excess gas will be sent to UNH's new and innovative renewable energy project.

Once construction on EcoLine is completed, the pipeline will not be visible, running four feet underground onto UNH property. At UNH, landfill gas will replace commercial natural gas in UNH's cogeneration plant.
