UNT Gets Extra Mileage Out Of Their Cafeteria

Denton County School Harvesting Kitchen Grease For Biodiesel

Reporting

DENTON (CBS 11 / TXA 21) ― The University of North Texas is turning cafeteria grease into biodiesel fuel that costs $1 a gallon.

A fully-automated biodiesel generator, called the Bio-Pro 190, takes 50 gallons of grease and turns it into 50 gallons of pure biodiesel fuel.

To make the fuel, a person adds oil, catalyst, methanol and sulfuric acid into the machine, they press a button and walk away. The entire process takes two days. Click here to see how the process works.

"Whatever you cook in there, it will have just a little bit of that smell," explained UNT Recycling Coordinator Doug Turnage. "If you cook fish, it'll have a slight fish smell to it."

The $8,400 machine is the latest addition to UNT's recycling program, which also found a way to make $56,000 by recycling 400 tons of paper and cardboard every year.

UNT has six cafeterias. The university thinks it can get 500 gallons of grease from them every month.

Eventually, 10 campus trucks will run on 100 percent biodiesel fuel. For now, they'll start with a blend.
