Located outside Jefferson, WI - Aztalan Bio is a biorefinery that utilizes a dry front-end fractionation system which separates corn components (starch, protein, germ) before the distillation process, leading to a wider range of products and potentially higher efficiency - producing corn oil, ethanol, corn germ, bran, and distillers’ grains. These outputs support a wide range of markets, including food production, animal nutrition, and renewable energy.

The plant has been in operation since 1898, first as a malting company and then, in 2006, was converted to ethanol production, becoming Wisconsin’s largest ethanol operation. Over the coming years, Aztalan Bio will undergo a similar transformation to its sister facility, Pannonia Bio in Hungary, to create a next‑generation biorefinery tailored to Wisconsin’s agricultural strengths and diversity.

Building on more than a century of history, this next chapter is about investing in people, progress, and community. With the revitalization of this historic plant and the hiring of a new workforce, we are creating opportunities for local employees while reinforcing generations of partnership with farmers.

Aztalan Bio is owned by Clon Bio Group who is family‑owned and invests in their people for long‑term success.
