NASA's Goddard Space Flight Center, Greenbelt, MD, will burn landfill gas to heat its buildings under a new contract awarded. "This project will prevent as much pollution as planting 68,000 acres of trees or removing 100,000 cars from Maryland highways by reducing harmful gases produced at the Center and the landfill" said Barry Green, Goddard energy manager. The sole-source contract was awarded to Toron Energy of Maryland, for utility service of landfill gas.
