Colorado ethanol producer Front Range Energy moves from corn to woody biomass
Ethanol producer Front Range Energy, based in Windsor, CO, has successfully tested a new process to make ethanol from waste wood. The company has a patented technology for making fuel from woody biomass instead of corn, and is the second major US ethanol producer to do so. Front Range will begin commercial production next year and plans to covert seven percent of its ethanol production from corn to woody biomass during that time. Switching over to that much biomass will reduce corn consumption by about 1.2 million bushels a year.
The Colorado ethanol producer has signed a 15-year, $100-million deal with Rochester, NY-based Sweetwater Energy to use Sweetwater's process for converting biomass to sugars, which are then distilled into ethanol. If that conversion process works well, Fort Range will increase its use of biomass. Sweetwater plans to acquire waste wood primarily from lumber mills. Some of it may come from beetle-killed pine (pictured), a source that's plentiful in Colorado.
National Renewable Energy Laboratory bioenergy engineer Jim McMillan said several firms nationwide are testing cellulosic ethanol processes and are moving toward commercial production. Freedom from corn ethanol may be in sight.
