Aztalan Bio LLC is the new owner of the former Valero ethanol plant in the town of Aztalan, WI. They are planning to revolutionize corn processing here in Wisconsin and reopen for production in the fall.

Jeff Oestmann, CEO of Aztalan Bio LLC says they have an innovative approach to biorefining that will put them on the leading edge of the transition to low- and zero-carbon renewable fuels. He explains more about the facility and how it serves as the next generation of biorefineries.

“We are thrilled to be reopening for production,” says Oestmann. “Our presence in the area will have a huge significance for the local agricultural economy as we create a new market for corn across the southern portion of the state.”

The facility will be producing around 110 million gallons of ethanol a year. What makes it notable compared to other processing plants is that it has front end dry fractionation. This means that they can separate all the constituents of corn, such as the germ, starch, gluten etc, and move them into different areas and sell those products separately or enhance and modify them into other products.
