Quincy Herald-Whig (March 25) -- Research at the Integrated Bioprocessing Research Laboratory at the University of Illinois continues to improve the dry-grind process used to produce ethanol from corn. "One of the major challenges in the dry-grind process is use of high corn solid loadings needed to achieve high ethanol concentrations and make distillation more economical," said Vijay Singh, director of IBRL and a professor in the U of I Department of Agricultural and Biological Engineering.
