Michigan University Uses Excess Mayonnaise To Generate Power

By Nicole Caldwell

In the quest to tap into renewable resources to power our homes, businesses, farms and industries, biogas is a particularly attractive option for its ability to take any organic material and turn it to power—a fact not lost on Michigan State University this past winter, when more than 1,200 gallons of mayonnaise was converted to fuel.

Atlas Obscura reports that last December, temperatures around the Midwest campus turned freezing and caused 500 containers of dining hall mayonnaise to turn. Every one of those containers held 2.5 gallons of the creamy white stuff, which was shipped to the school and served to students—who quickly complained that the flavor was off, The State News reported.

University policy is to donate unusable food to the local food pantry. But in this instance, the quantity was just too enormous for the food bank to take the donation.
