UW Technologies Developed Through the Great Lakes Bioenergy Research Center

The Great Lakes Bioenergy Research Center (GLBRC) is led by the University of Wisconsin–Madison, with Michigan State University as a major partner, and is one of three bioenergy research centers established in 2007 by the U.S. Department of Energy (DOE). Member institutions include a DOE National Laboratory, universities and a biotechnology company.

GLBRC is working to meet the nation’s need for a comprehensive suite of clean energy technologies, including next generation and drop-in fuels that can be used in today’s engines. The GLBRC's research supports the development of a robust pipeline from biomass production through pretreatment and final conversion to fuel, with sustainability providing a unifying theme.

UW–Madison has a rich history of developing and commercializing innovative technologies that benefit the world, including sustainable technologies. From engines that emit fewer pollutants to "smart" grids that enable more efficient use of power to solar heating and cooling systems, for decades UW–Madison scientists have been inventing solutions to the energy challenge, including several biofuels technologies developed through the GLBRC.
