"This paper follows the growing research of bioethanol fuels produced from farmed corn as well as corn\r\nstover in comparision to petroleum fuels. A Life Cycle Analysis (LCA) using the GaBi database was done\r\nto effectively compare results in terms of their respective emissions to the air, water, and industrial soil.\r\nVarious basis\u2019 that were also involved in the comparison include 1) Mass [kg], 2) TRACI \u2013 Global\r\nWarming Air [kg CO2-Equiv.], 3) TRACI, Acidification Rain [kg mol H + Equiv.], and 4) TRACI, Smog Air [kg\r\nNOx-Equiv.]. Production and processes of corn and petroleum from crude oils are also observed and are\r\nreplicated in the GaBi simulation. To normalize the three fuels, a functional unit of distance (km), and a\r\nconventional car (2001 Ford Taurus) was selected to describe the combustion of each fuel source based\r\non a travel distance of 100km on average road conditions.\r\nThe first section will illustrate the LCA conducted on gasoline and the results of the analysis.\r\nFollowing will show the LCA conducted for E85 produced from corn and corn stover, with\r\noverall results comparing each fuel source in the end.\r\nBased on LCA results, E85 was shown to have a 39% reduction in GHG emissions when compared to\r\ngasoline. The type of feedstock for ethanol production (corn versus corn stover) had little effect on the\r\nlife cycle emissions of E85, however, the resource inputs varied dramatically. To travel 100km, 12.9kg of\r\ncorn (food) and 190.4kg of water. In comparison, no food is required when corn stover is used as the\r\nfeedstock, however, 274.5kg of water is consumed.
