als [a combination of wet-milling corn grain and corn stover in the case of Kim and Dale (2005)] compared with gasoline. Luo et al. (2009) used energy, mass, and economic allocation in an LCA to assess corn stover ethanol production and reported that replacing gaso-line with ethanol reduces the levels of numerous

The life cycles of the fuels include gasoline production, corn and stover agriculture, cellulosic ethanol production, blending ethanol with gasoline to produce E10 (10% of ethanol) and E85 (85% of ethanol), and finally the use of gasoline, E10, E85, and ethanol. In this study, a substantially broader set of eight environmental impacts is covered. An LCA of corn-stover ethanol production for Ontario (Spatari et al. 2005) is available, but did not consider changes in soil carbon stocks resulting from stover removal, and there are no similar studies examin- ing the impact of corn stover collection for EtOH in Quebec.

2014-01-30 · The carbon intensity (CI) of corn ethanol—i.e., the greenhouse gas emissions produced via the production of a volume of the fuel—is declining, while the average CI of gasoline produced from petroleum sources is gradually increasing, according to a recent report prepared by Life Cycle Associates, LLC for the Renewable Fuels Association (RFA).

Int J LCA (2002) OnlineFirst 3 Corn oil is a coproduct in the wet milling process, in which ethanol, corn gluten meal and corn gluten feed are produced as well. Estimating the environmental burdens associated with corn oil requires the environmental burdens of the wet milling process, which are expressed as Equation (5). (5) where E corn LCA system boundaries of corn ethanol and CO 2 ‐to‐ethanol pathways. High‐purity CO 2 generated from the fermentation process is used as the feedstock for additional ethanol production through a gas fermentation process plus an electrochemical reduction process (Fig.
