Landfill gas powers Poet plant
Poet Biorefining-Chancellor, S.D., and Sioux Falls, S.D., have completed a landfill gas pipeline that is now providing methane gas to help power daily operations of the 105 MMgy Poet LLC 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. The plant will utilize the landfill gas in a wood waste-fuel boiler to generate process steam. Combined, the two alternative energy sources will initially offset up to 90 percent of the plant's process steam needs, currently met using natural gas, and has the potential to replace 90 percent of the plant's total energy needs (combined with waste wood) over time.
