About the Facility

In 1993, Metro Waste Authority formed a partnership with MidAmerican Energy and Waste Management to provide a safe and smart solution to an environmental problem -- landfill gas emissions.

  • Metro Waste Authority captures the landfill gas created when the garbage breaks down.
  • Waste Management oversees the plant that converts the gas into electricity.
  • MidAmerican Energy's power grid takes this electricity and powers area homes and businesses.

Previous to this solution, the gas was flared off into the atmosphere, wasting a valuable resource and potentially causing an environmental hazard. Landfill gas is comprised of approximately 55 percent methane and 45 percent carbon dioxide. Methane is the primary component of the natural gas commonly used for cooking and heating in homes.

Second Plant Launched in 2014

In February 2014, a second plant was completed to capture the methane gas and produce electricity.  The new plant provides 4.8 megawatts of energy to power 4,800 homes. The other plant produces 6.4 megawatts of energy. In the case of the new plant, the Municipal Energy Agency of Nebraska (MEAN) is the power grid delivering the electricity to area homes and businesses.
