The joint project by leading ethanol producer, POET, and the city of Sioux Falls uses landfill gas to help power POET’s Chancellor, South Dakota ethanol production facility. Methane gas created by the Sioux Falls Regional Sanitary Landfill is transported down an 11-mile pipeline to POET’s biorefinery, helping to power ethanol production.
Methane, a major factor in global warming, is captured, converted and put to use producing process steam for ethanol production–using methane offsets 15 percent of the facility’s energy needs, reducing overall CO2 emissions by more than 26,000 tons per year.

Revenue from selling methane to POET and subsequent carbon credits, earns an additional 1 million dollars per year for the city of Sioux Falls.
Earlier this month, the Environmental Protection Agency recognized the innovative work of the POET-Sioux Falls project in an award ceremony for programs that “employed unique project structures and took creative approaches to utilize (landfill gas) from municipal solid waste landfills.” The project will continue to grow as the supply of landfill gases increase, doubling capacity by 2025.
