Cardinal Ethanol, LLC, founded in 2005 and situated in Union City, Indiana, is a company dedicated to the manufacturing and distribution of fuel ethanol, distillers' grains, corn oil, and crude carbon dioxide. The firm, which was originally incorporated as Indiana Ethanol, LLC before adopting its current name in September 2005, supplies these products primarily within the continental United States, with a portion also being exported. The fuel ethanol produced by Cardinal Ethanol serves several critical functions: it enhances octane levels in fuels, acts as an oxygenate additive to reduce both ozone and carbon monoxide emissions, and offers a gasoline alternative not derived from petroleum. Furthermore, the company's distillers' grains are utilized as a valuable nutritional supplement for livestock in the dairy, beef, poultry, and swine industries. Its corn oil finds application as an animal feed ingredient, a crucial feedstock for biodiesel production, and in various other industrial sectors. Cardinal Ethanol also makes carbon dioxide gas available for sale. Distribution of its diverse product portfolio is managed through both direct sales and collaborations with third-party brokers.
