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).

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. 1).

Corn Ethanol Key conclusions • Corn grain ethanol has a slightly positive net energy on average, but is very dependent on – Ethanol production efficiency – Location and practices in corn production – Transportation distances • Improved corn yield, conversion and purification technology can help, but most gains are incremental

LCA of Corn‐Ethanol Systems. Direct‐effect life cycle energy and GHG assessment of corn‐ethanol considers the energy used for feedstock production and harvesting, including fossil fuels (primarily diesel) for field operations and electricity for grain drying and irrigation (Liska and Cassman 2008). 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). Selection of corn ethanol plant type affects LCA results Dry mill (nearly 90% of fleet) Wet mill Process fuel –Natural gas –Coal –Biomass Corn oil extraction Integrated production of corn and stover ethanol 11 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.
