Aztalan's story is just beginning and is off to a great start. Aztalan Bio and its sister company in Europe, Pannonia Bio, are the world's only two large grain processing plants equipped with dry front-end fractionation systems, serving as an essential launching point for biorefinery innovations.

Over the next several years, Aztalan will invest hundreds of millions of dollars into a biorefinery transformation uniquely suited to Wisconsin's strengths.

These innovations will support thousands of jobs, both directly and indirectly, and will result in annual greenhouse gas (GHG) savings in the millions of tons.
