  • U.s. Corn Usage for Ethanol Dry Mill Ethanol Co-Products

    Figure 2 breaks down the monthly corn usage for dry and wet mill fuel alcohols production. Corn usage in 2017 for dry mill ethanol production averaged 90 percent with the remaining 10 percent used in wet mill ethanol production. While there is some month-to-month fluctuation these percentages are nearly identical for 2016. "Our process does both and also will greatly reduce the need for natural gas to dry the non-fermentable material " he said in a release. The system would allow a standard dry-grind ethanol plant to produce several products on site including Corn oil for food and biodiesel A nutrient-rich feed ingredient for use in swine and poultry production
