The power of landfill gas is being demonstrated in three U.S. locations. Ethanol plants in Nebraska and Missouri are using landfill gas to replace natural gas, while a North Carolina project plans to generate electricity.

Mid-Missouri Energy Inc., a 40 MMgy ethanol plant in Malta Bend, Mo., plans to displace more than 90 percent of its natural gas usage with landfill gas supplied by Johnson County Landfill in Shawnee Mission, Kan. The deal signed in July requires the landfill to provide the ethanol plant with up to 3,300 million British thermal units per day of pipeline-quality biogas.
