Ethanol is an alcohol-based alternative fuel. The fermented product of corn starches, ethanol can be made by dry-mill, wet-mill, or biomass processing. Through one of these processes, corn is fermented, distilled, and separated into a starch-filled liquid (ultimately become ethanol), solids, and corn oil. These co-products and by-products from ...
