Using fast pyrolysis to extract sugars from biomass could become the most cost-effective way to produce biofuels or renewable chemicals, according to a team of researchers from Iowa State University. "The Department of Energy has been working for 35 years to get sugar out of biomass. Most of the focus has been on use of enzymes, which remains extremely expensive," said ISU researcher Robert C. Brown. "What we've developed is a simpler method based on the heating of biomass," Brown added.
