Unorthodox antioxidant focus drives Stover Ventures towards cellulosic dream
A remarkable and usually under the radar company known as Stover Ventures is said to be nearing its once-unliekly goal of raising capital — mostly so far from Iowa farmers — to construct a biorefinery near Osage, Iowa which will convert up to 14,400 tons per year of corn stover into a neutraceutical extract and a treated animal feed which tests are showing has a 71% higher digestability rating than a standard control feed in a University of Wisconsin trial.
But its the antioxidant product that drives the economics. The Stover Ventures team projects a 3 percent yield from corn stover and a value of $35 per kilogram for the extract.
