UNH Uses Garbage to Go Green


Colleges are going green all over New England by installing solar arrays to illuminate campus paths to starting grassroot groups to pressure politicians to pass carbon limiting laws. There is even an effort to make students take shorter showers to save on heating hot water.

But few are doing as much as the University of New Hampshire. The five million square foot campus is now getting up to 85 percent of its electricity and heat from a nearby landfill’s methane gas. It is the first university in the country to use landfill gas as its main fuel source.

Called Ecoline, the project gets its methane from a landfill at Waste Management’s Turnkey Recycling and Environmental Enterprise in Rochester. Methane is a natural by-product of decaying waste and is collected via 300 extraction wells and miles of collection pipes.

After the gas is purified and compressed, it travels through a 12.7 mile pipeline to UNH’s power plant where it is replacing commercial natural gas.
