ifying and adding nutrients back into the pretreated cellulose are three separate steps," Dale said. "Each step is expensive and adds to the cost of the biofuel. Breaking down cellulose into fermentable sugars cost effectively has been a major issue slowing cellulosic ethanol production. Using AFEX as the pretreatment process can dramatically reduce the cost of making biofuels from cellulose."

The next step could be a pilot plant, Dale said, perhaps at MBI International. MBI, a subsidiary of the MSU Foundation, partners with universities and companies to commercialize technology.

"There are several companies including the Mascoma Corp., which plans to open one of the nation's first cellulosic ethanol plants here in Michigan that may be interested in using this technology," Dale said. "We are working to make the AFEX technology fit these companies' needs."
