The RIN credit a biofuel receives is based on the combination of feedstock, fuel and process that produce it. We applied both LCA and SWA to assess the GHG impacts of ethanol based on Iowa corn. Growing corn in rotation with soybeans generated 35% less GHG emissions than growing corn after corn. Based on average corn production, ethanol's GHG benefits were lower in 2007 than in 2006 because of an increase in continuous corn in 2007. Cellulosic ethanol should earn producers carbon reduction credits, higher than those given to producers who grow corn for ethanol, which is about 3 to 20 cents per gallon. It takes 0.76 J of energy from fossil fuels to produce 1 J worth of ethanol from corn.

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.

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.

Our BAU scenario assumes a continuation through 2022 of current trends in average corn yields per hectare, process fuel switching from coal to natural gas, and increasing fuel efficiency in heavy -duty trucks.

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. 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.

av P Paulsson · Citerat av 4 — Abstract. In this thesis an energy analysis of ethanol production at the ethanol plant of fabrik i Winnebago, Minnesota, som drivs av ett kooperativ kallat Corn Plus har i in agriculture- a comparing study using Life Cycle Assessment (LCA).

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.

The battle over corn-based and sugarcane-based ethanol — which one is cheaper? — has been brewing for weeks, and I’ve received emails and tweets last week about statements released from both camps: the Renewable Fuel Association (RFA) and the Brazilian Sugarcane Industry Association (UNICA).
