Two ethanol plants were honored by the Environmental Protection Agency on Tuesday with the Energy Star Combined Heat & Power Award. POET Biorefining in Ashton, Iowa, and East Kansas Agri-Energy, LLC in Garnett, Kan., were recognized with the award for reducing energy consumption and greenhouse gas emissions.
In April 2004, POET began full production at an ethanol plant in Ashton. Electricity is generated by a natural gas-fired turbine, which requires approximately 16 percent less fuel than typical on-site thermal generation and purchased electricity. Based on this comparison, the system reduces carbon dioxide emissions by an estimated 18,900 tons per year, which is equivalent to removing the annual emissions from 3,100 cars or planting 3,900 acres of forest.
The East Kansas Agri-Energy dry mill ethanol plant in Garnett, Kan., began production in 2005. The steam turbine system generates approximately one-third of the facility’s electrical demands. It requires approximately 23 percent less fuel than typical on-site thermal generation and purchased electricity. Based on this comparison, the plant reduces carbon dioxide emissions by an estimated 14,500 tons per year, which is equivalent to removing the annual emissions from 2,400 cars or planting 3,000 acres of forest.
The ENERGY STAR award recognizes projects that reduce emissions and use at least five percent less fuel than state-of-the-art comparable separate heat and power generation.
