Janesville, Nov 30 - Seven students from Minnesota State University, Mankato’s agroecology class visited Guardian Energy on Nov 17 to learn more about ethanol production. 

During their visit, the students gained a better understanding of the various components of the ethanol production process such as incoming grain grading, grain handling, fermentation, grain storage, dried distillers grain production and storage, ethanol storage and shipment.

The students were also briefed on Minnesota’s ethanol industry. 

“As producers of clean, renewable energy from locally-grown corn, we are always happy to welcome students interested in learning more about ethanol production. These tours also provide us with an opportunity to talk more about the positive impact our industry has on strengthening rural economies, reducing greenhouse gas emissions, reducing prices at the pump and promoting energy independence,” said Jeanne McCaherty, CEO of Guardian Energy. 

Minnesota State Mankato’s tour of Guardian Energy was the second time students from the university have visited Guardian Energy this year. In September, students from its bioengineering class visited the plant.

Both tours were organized by the Minnesota Bio-Fuels Association (MN Bio-Fuels). Guardian Energy is a member of MN Bio-Fuels. 

Chris Ruhland, professor of biological sciences at Minnesota State Mankato, accompanied his students on the Nov 17 tour.

“More than ever, students recognize that renewable fuels are becoming an increasingly important part of the global economy. Having students observe how ethanol is made – from the unloading of corn kernels to the loading of ethanol into tank cars, students get to see the entire process close up. A firm understanding of how the energy contained within the corn kernel is extracted is an essential part of our agroecology class,” he said.
