After reviewing this study, I found that this report has many flawed assumptions and overlooks some fundamental facts about ethanol production, which anyone familiar with ethanol in any detail would know. First of all, assuming that putting land into biofuels production rather than feed production would result in new land having to be used to replace that feed is erroneous. In fact, the process of fermenting corn starches to produce ethanol outputs a high value by-product...animal feed. It is called distillers grain that has even more protein content than soy feed (protein comes from the yeast added to a fermenter to convert glucose to ethanol). The distillers grain is better for animal digestion, and in Europe all grains are purposefully distilled before feeding to animals (to prevent stomach irritation and improve the nutrition of the feed). So basically you would get two products from one field of corn-ethanol and distillers grain...not just ethanol. How was this essential detail over looked by these so called experts???
