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 calculated emissions across models ranged from 16 to 45 for sugarcane, 43–62 for corn, and 45–68 g CO 2 eq MJ −1 for wheat ethanol. Harmonizing the three public models with VSB assumptions for sugarcane ethanol produced in Brazil, the range was reduced to 16–17 g CO 2 eq MJ −1 for sugarcane ethanol. LCA FOR RENEWABLE RESOURCES Life cycle assessment of bio-based ethanol produced from different agricultural feedstocks Ivan Muñoz & Karin Flury & Niels Jungbluth & Giles Rigarlsford & Llorenç Milà i Canals & Henry King Received: 3 August 2012 /Accepted: 11 June 2013 # Springer-Verlag Berlin Heidelberg 2013 Abstract While this LCA was on greenhouse gas emissions and not the energy gains/losses from producing ethanol, the calculation does show that even if you look 30 or 100 years into the future, the benefits of corn ethanol over gasoline depend highly on the production method (some methods actually increase emissions relative to gasoline). 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.

(2012), Environ. Research Letters and CO2 Figure 1 illustrates the Iowa Corn (Kernel) Ethanol Monte Carlo LCA results compared to four published studies, all with the same system boundary, as reported by Farrell. This is used to validate the Monte Carlo approach and to clarify the debate over the energy benefits of corn kernel ethanol (Figure 1) (3). products like corn stover. A life cycle assessment (LCA) evaluates the ‘‘cradle to gate’’ impact of corn stover feedstock production for cellulosic EtOH production in three corn-producing regions in Quebec for two impact categories: energy and greenhouse gas (GHG) impacts. This study focuses only on corn stover-based ethanol as one case. Further studies may include other types of cellulosic feedstocks (i.e., switchgrass or wood), which require less intensive agricultural practice and may lead to better environmental performance of fuel ethanol.

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. 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).

Keywords: life cycle assessment (LCA), bio-ethanol, CO2 balance 1 INTRODUCTION Bioethanol derived from biomass is often considered a significant contributor for a sustainable transportation fuel.

In this study, a substantially broader set of eight environmental impacts is covered. Emissions ranged from 16 to 45 for sugarcane and 43–62 g CO 2 eq MJ −1 for corn ethanol. • LCA tools produce similar results when harmonized to the maximum possible extent.

The study also states that when ethanol is refined at natural gas-powered Since 2010, the RIA LCA for corn ethanol has dominated policy discussions and federal regulations related to ethanol as a renewable fuel and a GHG mitigation Carbon Intensity of Marginal Petroleum and Corn Ethanol Fuels.
