Want to meet the King of the Netherlands? Go to Emmetsburg, Iowa, Wednesday and see His Majesty Willem-Alexander break a wooden shoe across the bow of the first commercial-scale cellulosic ethanol plant in the country.
The King is coming because Dutch bioscience firm Royal DSM has partnered with Sioux Falls-based ethanol producer POET in Project Liberty, an effort to make ethanol out of something other than stuff we eat. DSM has developed the enzyme that breaks down corn-waste cellulose; POET has built the new processing plant in Emmetsburg that will use DSM's biotech to turn 770 tons of corn stover (cobs, leaves, husks, and stalks) into 20 million gallons (and eventually 25 million gallons) of cellulosic ethanol each year.
A UNL study earlier this year contended that making biofuel from corn stover would do more harm than sticking with gasoline by removing biomass from the soil and reducing farmland's capacity to capture carbon dioxide. The EPA says the study is based on the erroneous assumption that cellulosic ethanol harvesting would remove all of the stover from farm fields. POET says it is promoting sustainable corn waste harvest methods that would leave about 75% of the biomass on the ground to maintain soil nutrients and prevent erosion. We have to burn more fuel to make more passes over the corn fields to collect this biomass, but POET says removing excess corn waste will allow farmers to make fewer tillage passes over their fields to incorporate the remaining residue or make it easier to go to no-till farming.
So welkom Koning Willem-Alexander, and gefeliciteerd en veel geluk to Poet and DSM on making celluslosic ethanol commercially viable.
