by Nat Williams (Illinois Farmer Today) A handful of farmers are not just raising the crops that can be used as biofuels. They’re also working on producing the fuel itself. A Minnesota-based company is in the developmental stage of offering small-scale production of ethanol and other end-products right on the farm. Mark Gaalswyk of Easy Energy Systems describes the process by using a popular toy as an analogy.
“It’s a Lego concept,” Gaalswyk told farmers at the Family Farms group annual winter conference here. “There are different parts of the process. If one part becomes obsolete, you can replace it with another part.”
The company manufactures modules that can be linked to build “micro biorefineries” right on the farm. Feedstocks include corn, grain sorghum, sugar beets and unharvested waste products, such as fruits and vegetables.
“Long term, there is a lot of interest all over the world,” Gaalswyk said.

Gaalswyk said the company’s engineers are testing 47 different feedstocks to determine feasibility of manufacturing various end-products. One project involving the manufacture of n-butanol is being tested on the Iowa farm of Harry Stine, founder of Stine Seeds. He said another project is being tested with cooperation of the Koch brothers, billionaire entrepreneurs and owners of Koch Industries.
Easy Energy is also working with Iowa State University on cellulosic technology. The company will soon begin building initial modules that convert feedstocks into sugar water and then into n-butanol. READ MORE
