ISU study, EPA analysis indicate vast potential for POET's cellulosic process
Sioux Falls, SD (PRWEB) May 21, 2009 -- Corn cobs are both economical and environmentally friendly as a feedstock for cellulosic ethanol, university and government reports indicate, reaffirming POET's strategy for commercializing its new technology.
Removing corn cobs from fields for use in cellulosic ethanol production appears to have no substantial impact on soil nutrient content, based on results from the first year of a multi-year study by Iowa State University (ISU).
POET's process for producing cellulosic ethanol uses corn cobs as the feedstock. POE's pilot-scale plant in Scotland, S.D. is already producing cellulosic ethanol at a rate of approximately 20,000 gallons per year, and plans are on schedule for 25 million gallons per year of commercial production in Emmetsburg, Iowa in 2011.
The ISU research was funded by POET as part of the company's ongoing internal study into the sustainability of using corn cobs as a cellulosic feedstock.
Results from the first year of the study, conducted on a test field near the Emmetsburg site, indicate that fertilizer treatment for a field in which cobs have been removed would be almost identical to treatment of a field in which cobs were not removed. ISU researchers will continue their work this year on the test plots, compiling more data to help farmers manage their land well while taking advantage of an additional revenue source from their fields.
"This information reinforces previous research showing that corn cobs are a sustainable, environmentally friendly feedstock for producing cellulosic eth
