South Dakota, United States [RenewableEnergyWorld.com] Poet Biorefining – Chancellor and the city of Sioux Falls, South Dakota have completed a landfill gas pipeline that is now providing methane gas to help power daily operations at the 105 million gallon per year (MGPY) Poet ethanol plant.
The 10-mile, low-pressure pipeline from the Sioux Falls Regional Sanitary Landfill began supplying methane to the plant at the end of February, ahead of the expected completion date. The Poet plant will use the landfill gas in a wood waste-fuel boiler to generate process steam.
Combined, the two renewable energy sources will initially offset up to 90 percent of the plant’s process steam needs currently being met with natural gas. The solution has the potential to replace 90 percent of the plant’s total energy needs (combined with waste wood) over time, the company said.
“At Poet, we take a lot of pride in helping reduce the human impact on our environment,” said Jeff Broin, Poet’s CEO. “Ethanol already cuts greenhouse gasses significantly compared to gasoline. This partnership makes that process even cleaner.”
Poet and the City of Sioux Falls are members of the U.S. Environmental Protection Agency’s Landfill Methane Outreach Program (LMOP). The program aims to reduce methane emissions from landfills by encouraging development of cost-effective and environmentally sound landfill gas projects.
