Project Profile

L.P Gill Landfill and Siouxland Ethanol Project

  Self Developed (Absence of third party developer)

Jackson, Nebraska
End User(s):
Siouxland Ethanol LLC
Industrial (ethanol production)
L.P. Gill Landfill
Landfill Size:
3 million tons waste-in-place
Project Type:
Direct Thermal (thermal oxidizer)
Project Size:
600 standard cubic feet per minute (scfm)
$250,000 per year in fuel costs
Environmental Benefits:
Carbon sequestered annually by 15,100 acres of pine or fir forests, annual greenhouse gas emissions from 13,500 passenger vehicles, or carbon dioxide emissions from more than 165,000 barrels of oil consumed. Annual energy savings equate to heating 2,000 homes. Estimated emissions reductions of 0.019 million metric tons of carbon equivalents.

Ethanol production facility, where landfill gas is used to offset energy needs.

The L.P Gill Landfill, in partnership with Siouxland Ethanol, is harvesting energy from its 3 million tons of waste. Fully operational since April 2008, the L.P. Gill Gas Recovery Project, located in Jackson, Nebraska, collects landfill gas (LFG) produced by the landfill and sells it to Siouxland Ethanol, where it is blended with natural gas to power a 50 million gallon per year ethanol production facility.

The infrastructure of the project includes 42 wells, two blowers, a gas purification system, and a 1.25-mile pipeline between the landfill and Siouxland Ethanol. The methane provided by the landfill reduces Siouxland Ethanol's annual natural gas requirements by 10 percent. Furthermore, LFG is available to Siouxland Ethanol at a lower cost than the replaced natural gas, saving an estimated $250,000 annually.

In addition to revenue provided by the sale of the landfill methane, the project also has qualified to be a 'carbon offset provider,' for its destruction of methane and for the displacement of fossil fuel use.

Without the sale of methane and carbon credits, a collection system was simply too expensive for a medium-scale operation such as ours. —Leonard Gill, Owner/Operator of the L.P. Gill Landfill
