Corn is the usual feedstock for producing ethanol in the U.S, but wood could open up the growing market to states outside of the Midwest. Researchers at the SUNY College of Environmental Science and Forestry (ESF) say they have invented a method for removing energy-rich sugars from wood, a process that could help develop agricultural feedstocks for ethanol production, and increase profits for New York's and other states' pulp and paper industries.

"You can also extract these components from grasses, but grasses go dormant in the winter and they're difficult and expensive to store for use in a year-round process. And trees are dense. They can be shipped and stored economically, and they are more efficient energy collectors than annual crops. After the desired components are extracted, the residue can be burned or gasified for combined heat and power uses." - Dr. Thomas E. Amidon
