Cob collection trials for cellulosic biomass successful

Texas harvest kicks off POET research for 2009

Monday, July 27, 2009

The first cob collection of 2009 is complete as POET continues to work with agricultural equipment manufacturers and farmers to find the most efficient and affordable means for harvesting cellulosic feedstock.

Equipment for harvesting corn cobs was tested in fields near Harlingen, Texas from July 6 – July 22. The trials were a precursor to larger harvesting efforts this fall. In all, the effort will see as many as 25,000 acres harvested in Texas, South Dakota and Iowa.

Corn cobs are already used by POET at its pilot cellulosic plant in Scotland, S.D. and will be used at its first commercial cellulosic ethanol plant, Project LIBERTY, in Emmetsburg, Iowa in 2011. Project LIBERTY will produce 25 million gallons of cellulosic ethanol per year.

“Agriculture equipment manufacturers are putting the final touches on a variety of harvesters that will be on the market soon,” said Scott Weishaar, Vice President of Commercial Development. “Farmers will have a lot of ways to take advantage of corn cobs as a new revenue stream.”

POET will continue work with 15-20 farmers in the Emmetsburg area in further tests this fall and will purchase cobs for use in Project LIBERTY.

“Farmers will play a big role in our nation’s energy future,” Weishaar said. “Their support has been instrumental in the success of grain-based ethanol and will continue to be crucial in commercializing cellulosic ethanol.”

About POET
POET, the largest ethanol producer in the world, is a leader in biorefining through its efficient, vertically integrated approach to production. The 20-year-old company produces more than 1.54 billion gallons of ethanol annually from 26 production facilities nationwide. POET recently started up a pilot-scale cellulosic ethanol plant, which uses corn cobs as feedstock, and will commercialize the process in 2011. For more information, visit
