Three other GM facilities – an engine plant in Toledo, Ohio, and assembly plants in Michigan and Indiana – also use landfill gas to power plant boilers, and a fifth project is underway at an assembly plant in Oklahoma City.
GM’s service parts operations headquarters in Grand Blanc, Michigan also uses landfill gas by purchasing eight million kilowatt-hours of electricity annually, generated from the Granger Energy landfill gas-to-electricity project.
According to the World Resources Institute and the Green Power Market Development Group, GM is the largest non-utility user of landfill gas in the US.
“All of GM’s landfill gas projects have proven to save money, generating annual savings greater than $US500,000 at each plant,” a spokesman said.
GM has reduced its natural gas consumption 21% since 1995.
Landfill gas is 50% methane and is released from waste as it decomposes in landfills.
