Founded in 1994, Al-Corn is located in Claremont, MN. For two decades Al-Corn Clean Fuel has created a guaranteed and stable market for corn, maintained a strong cash position during an uncertain economy and made investments that added significant value for members and their local communities.
The Al-Corn Clean Fuel plant utilizes a dry milling process, the most commonly used method in the ethanol industry. The whole corn kernel is ground into a powder, mixed with recovered process liquids to form a mash (similar to oatmeal) and then cooked with enzymes that turn the starch into glucose. Yeast is added and the mash is fermented.
The resultant “beer” is distilled to separate the ethanol from the solids and remaining liquids. These are further processed to recover liquids for the mashing process, and to produce high protein livestock feed and corn oil.
Annually Al-Corn grinds almost 42 million bushels of corn and produces 125 million gallons of ethanol. In addition, the plant produces 269,000 tons of high protein livestock feed and 44 million pounds of corn oil. The majority of these products are consumed by refiners, livestock feeders, meat packers and biodiesel producers throughout Minnesota. Al-Corn ships its products to markets across the United States and around the world.
The company is an industry leader in the utilization of the best available control technologies in order to reduce energy consumption and production costs, thereby increasing efficiencies and reducing emissions.
In 2006 the Claremont, MN plant utilized approximately .802 Kilowatts Hours (KWH) per gallon of ethanol produced. Today, Al-Corn has reduced that number to .185 KWH per gallon of ethanol produced. This incredible reduction is due to the installation and operation of a combined heat and power unit (CHP) which burns natural gas to generate both electricity and steam.
In addition, the Al-Corn plant has reduced water consumption to 2.2 gallons of water per gallon of ethanol produced and was the first plant to achieve “zero liquid discharge”. The environmental benefits of these best practices include increased water available to local streams and wetlands, as well as their natural inhabitants.
Energy conservation efforts have reduced the plant’s energy use by more than 38% compared to the original plant design.
