Who is Aztalan Bio?

Aztalan’s story is just beginning, and you can be part of it!  ClonBio Group acquired Wisconsin’s largest ethanol plant in 2022 located in the village of Aztalan, just outside Jefferson, WI.  The facility will process 40 million bushels of locally grown feed corn per year, turning that into food-grade corn oil, vegetable protein concentrates and isolates for food applications, aquaculture feeds, renewable natural gas, organic fertilizer, ethanol, and dietary fiber for foods, among other things.  We are scheduled to start the facility in the fall of 2023 and are currently hiring! 

Aztalan’s sister facility, Pannonia Bio in Hungary is one of the most technologically advanced grain biorefineries in the world.  Over the next several years, Aztalan will invest hundreds of millions of dollars into a biorefinery transformation every bit as innovative as Pannonia’s but uniquely suited to Wisconsin’s strengths.  Aztalan Bio is owned by ClonBio Group who is family-owned and invests in their people for long-term success.  We have a dedicated internal team of engineers and scientists from 23 countries and 5 continents, an investment in people that explains why ClonBio’s biorefineries are so technologically advanced.
