Argument: Corn feedstock is a beneficial biproduct of corn ethanol production

Issue Report: Corn ethanol

Support

The byproduct of ethanol production is a protein-rich animal food that is approximately one third the weight of the corn that comes into the ethanol plant. Although the production of ethanol reduces the corn weight by two thirds, it doesn’t change the protein content. Ethanol production reduces the feed bulk but not the feed value of corn. This byproduct is currently better fed to cows than to chickens or pigs (at least for now), but certainly isn’t taken out of the animal food supply.
In reality, the current concern in the industry is that the boom in ethanol demand will create a glut of this type of feed, not a shortage. The bulk of the corn going into the human food category goes into high fructose corn syrup, which currently sells for more than four times ethanol’s value, making it unlikely that its production will decrease in favor of ethanol.
Biofuels produced incidentally to food-crop agriculture are suboptimal in several dimensions, but their production and consumption in the medium term gives us the time and creates the infrastructure necessary to achieve more optimal production from engineered non-food crops and improved processes.”
