Not A Joke - Wisconsin Clearing Icy Roads Using Cheese Brine (Provolone, Mozz Best)
MILWAUKEE — In a state whose license plates advertise it as America’s Dairyland, where lawmakers once honored the bacterium in Monterey Jack as the state’s official microbe and where otherwise sober citizens wear foam cheesehead hats, road crews are trying to thaw freezing Wisconsin streets with a material that smells a little like mozzarella.
This month, Milwaukee began a pilot program to repurpose cheese brine for use in keeping city roads from freezing, mixing the dairy waste with traditional rock salt as a way to trim costs and ease pollution.
“You want to use provolone or mozzarella,” said Jeffrey A. Tews, the fleet operations manager for the public works department, which has thrice spread the cheesy substance in Bay View, a neighborhood on Milwaukee’s south side. “Those have the best salt content. You have to do practically nothing to it.”
Local governments across the country have been experimenting with cheaper and environmentally friendly ways of thawing icy thoroughfares, trying everything from sugar beet juice to discarded brewery grain in an attempt to limit the use of road salt, which can spread too thin, wash away and pollute waterways.
