USDA researchers develop inexpensive way to grade the ethanol potential of perennial grasses at the biorefinery loading dock

The researchers, including Michael Casler of Madison, WI, developed the first use of near-infrared sensing (NIRS) to measure 20 components in switchgrass? biomass? that determine its potential value to biorefiners. These components include cell wall sugars, soluble sugars and lignin. With this information, 13 traits can be determined, including the efficiency of the conversion from sugars to ethanol.

Anerobic Digestion and Biogas

UW Extension have created seven modules focused on the use of anaerobic digestion technologies. Details of the process are introduced, as well as factors that influence start-up, operation and control of anaerobic digesters at different scales.
