Cheese Brine to be Used in Place of Road Salt
Brine is a liquid cheese-making byproduct; if you’ve bought fresh mozzarella, it often comes floating in the stuff. To cheese-makers, it’s a hassle — they spend many thousands of dollars to dispose of cheese brine each year, trucking it to wastewater treatment plants.
Several years back, a rural highway employee named Emil Norby — people call him Moe — had a flash of inspiration. What if this salty brine could be used on icy roads, a companion for rock salt and sand? “I knew we had a lot of dairies looking to get rid of this stuff,” Norby says. “I figured why not give it a whirl.”
In the first year alone, tiny Polk County saved $40,000 in rock salt costs. Conversely, F&A Dairy saved on brine disposal costs — to the tune of nearly $30,000. “Everybody wins,” says Chuck Engdahl, F&A’s wastewater manager.
