Ethanol Industry Responds to "Flawed" Study



(NAFB)--A study from the University of Nebraska was recently published in Nature Climate Change and suggests using corn residue to make ethanol and other biofuels reduces soil carbon and can generate more greenhouse gases than gasoline. 25x’25 says the study offers nothing beyond what biofuel interests already understand - that excessively removing agricultural residue from the soil has negative impacts on climate. Growth Energy CEO Tom Buis says the conclusions reached in the study are flawed. For one thing - Buis says the study’s authors assume all 10 Corn Belt states would be harvesting 75-percent of corn stover - which is unrealistic and beyond what any cellulosic ethanol producers are actually considering. He says both USDA and EPA have refuted the study and called out the authors’ unrealistic assumptions - concluding the study doesn’t provide useful information relevant to the life cycle of greenhouse gas emissions from corn stover ethanol.  When it comes to reducing greenhouse gas emissions - Buis says a long-term, comprehensive approach that successfully partners first and next generation fuels is necessary - not a short-sighted, unrealistic and misleading study.
