Hyrax Energy, Inc. ("Hyrax") is a private company dedicated to enabling a bio-based economy. The company's ionic liquids platform combines hydrolysis chemistry developed at the University of Wisconsin with a separations technology developed by the company that recycles the ionic liquid very efficiently. The process performs at high yields starting from forestry residues, corn stover or dedicated energy crops and produces clean, concentrated fermentable sugar and intact, pure lignin products that can be converted into innumerable chemicals, materials and drop-in fuels.

Hyrax is the first company to emerge from the Department of Energy funded Great Lakes BioEnergy Research Center (GLBRC) and has licensed technology from the Wisconsin Alumni Research Foundation (WARF).
