Via the Wisconsin governor:

Let me recognize another innovator who did more with what he had, who saw more than just a cheese processing plant at the crossroads of a small central Wisconsin town. This is someone who took the leftover ingredients of cheesemaking – whey permeate – and found a way to turn it into a renewable fuel. He then set up a local distribution network for his cheese-based ethanol. I am proud to introduce Joe Van Groll.
You know, in other places, they just eat cheese. But here we wear it on our heads when we watch football and now, thanks to Joe, Wisconsin is the state where we can even use it to drive our cars.
Creativity, ingenuity and innovation have always been behind the hard work that allows us to meet our challenges. Let’s not forget to think in new ways as we work to protect Wisconsin’s values, rebuild jobs and lay a foundation for growth.
