What are the by-products of making ethanol?
Years ago we sold land to Continental Carbonics, for them to construct a building. We send them our CO2, which they compress into a liquid in order to make dry ice and dry ice pellets. The latter is used for sandblasting, rather than sand. We sell our DDG, dried distilled grain. With the syrup on it, it was called DDGS, which stands for dried distilled grain solubles. Now that we have taken the syrup out of the equation—we burn that to make steam to power our facility—with the syrup off, the fat content of our feed has been reduced. But our feed looks a lot nicer now than when it had the syrup on it, when the increased heat from drying the syrup made the product look darker. Are you making a corn de-icer? No, not now. About seven years ago we were looking into using the syrup for that purpose. But now we have a much better use for it. What about zein? Zein is a form of starch—and by-product of corn—we looked at five years ago. But the process of getting the zein out—the technology wasn
