    Abstract

    A life cycle assessment study on ethanol production in an integrated biorefinery is presented. The feedstock is corn grain as starch based biomass, and corn stover or switchgrass as lignocellulosic biomass. The system boundary includes biomass production, transportation of biomass to an integrated biorefinery, integrated biorefinery processes, transportation of ethanol to users, and ethanol fueled vehicle operation. Ethanol was used as a liquid fuel in a compact passenger vehicle in the form of E10 (a mixture of 10% ethanol and 90% gasoline by volume). The Ammonia fiber explosion process was used to pretreat corn stover and switchgrass, and a dry milling process was used as the starch based biorefinery. The potential impact categories considered were nonrenewable energy consumption, fossil fuel use (coal, crude oil, and natural gas), climate change, photochemical smog, acidification, and eutrophication. Environmental impacts were estimated by characterization factors given by the EPA. This is an abstract of a paper presented at the 2006 AIChE Annual Meeting (San Francisco, CA 11/12-17/2006).
