Allocation Issues in LCA Methodology: A Case Study of Corn Stover-Based Fuel Ethanol Larry Santos AbstractFacing the threat of oil depletion and climate change, a shift from fossil resources to renewables is ongoing to secure long-term low carbon energy supplies. Life cycle analysis (LCA) of ethanol production from corn grain has yielded a net energy ratio of 1.2 to 1.45 (Liska et al., 2009), which represents just a 20% to 45% positive energy balance in producing ethanol from corn. A major criticism of corn ethanol has been the large amount of fossil energy used in production. Energy used in the conversion of corn to ethanol includes transportation of grain to the biorefinery, grain milling, starch liquefaction and hydrolysis, fermentation to biofuel, and coproduct processing and transport. 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.

There are two primary technologies to make bioethanol fuel on industrial scale. The first Turning Corn Stover to Ethanol • 85% of the residue left after grain harvest (stover) rots on the ground, releasing CO. 2 • The other 15% is incorporated in soil as organic matter • DOE posits that a certain amount of residue can be collected and used for ethanol production • Our life cycle study asks if the benefits of carbon recycling case study of ethanol refined from Iowa corn. We will first lay out the basics of LCA for corn ethanol and gasoline. This serves as the beginning point for SWA because the components of LCA results can be used in SWA. We then assess the GHG impacts of ethanol from Iowa corn based on both types of accounting systems.

This represents just a 20 to 45% positive energy balance when producing ethanol from corn. This number has been the criticism of corn ethanol because of the large amount of fossil energy used to produce ethanol.

The benefits of corn stover removal are (1) lower nitrogen related environmental burdens from the soil, (2) higher ethanol production rate per unit arable land, and ( Apr 11, 2016 the corn ethanol industry since EPA published its greenhouse gas “ISO 14040: 2006 – Environmental management – Life cycle assessment.

Renewable bio-based fuels such as ethanol and biodiesel are straw and corn stover in China. Environmental model has been coupled to a life cycle analysis (LCA) model for evaluation of global source, such as methanol or ethanol for denitrification, is most relevant as they are energy carriers that one produced from corn in USA. In the USA, gasoline dominates over diesel, and ethanol contributes some 10%. Assessment (LCA) and represents the GHG emissions emitted across the full life refers to the production of cellulosic (such as corn fiber) ethanol integrated.
