Like ethanol, biobutanol is an alcohol that can be produced through processing of domestically grown crops such as corn, sugar beets, and other biomass such as fast-growing grasses, and agricultural waste products. The ability to produce butanol from biomass sources via fermentation has existed since the early 1900s. However, these older biobutanol processes are more expensive than todays petrochemical production processes. Today, butanol is produced almost entirely from petroleum. Renewed interest in butanol as a sustainable vehicle fuel has led to the development of improved biobutanol production processes. DuPont® and BP® are making biobutanol the first product of their joint effort to develop, produce, and market next-generation biofuels.
