Corn Milling, Processing and Generation of Co-products

1970's and recent clean air legislation have contributed to an expanded dry-mill industry. Currently legislative issues are before Congress that could triple the demand for ethanol as an oxygenate component in gasoline. This increased ethanol demand will likely come from the dry-milling of corn thereby offering an increased amount of co-products.
