POET signs on for another decade of landfill gas for Chandler plant

In South Dakota, POET has signed on for another 10 years of using methane extracted from the Sioux Falls landfill for use at its Chandler ethanol plant. During the past decade, by using 5.7 million BBTUs worth of methane from the landfill instead of natural gas, the company has saved 200,000 metric tons of CO2 emissions from its ethanol production process. The first decade saw the company pay about $17 million for the energy but the new contract is valued at $12.7 million for the next 10-year period.
