Iowa State researchers using ultrasound to breakdown cellulosic feedstock

July 1, 2013 |

In Iowa, all chefs know that “you have to break some eggs to make an omelet,” and that includes engineers at Iowa State University who are using high-frequency sound waves to break down plant materials in order to cook up a better batch of biofuel. Researchers have shown that “pretreating” a wide variety of feedstocks (including switch grass, corn stover, and soft wood) with ultrasound consistently enhances the chemical reactions necessary to convert the biomass into high-value fuels and chemicals.
