I've heard it implied and outright stated numerous times that corn based ethanol was at least partially responsible for rising food costs. This has never made any sense to me. My reasoning: A) The majority of corn goes to feeding livestock B) When producing ethanol, there are wasteproducts which are DDG or DDGS (Dried distillers grain) C) Both of the waste products can be fed to livestock. D) DDG is suppose to have near the same level of nutrients as traditional feed. DDG is also far more compact, which should ease transport costs. So why would corn based ethanol affect food prices? What am I missing?
