Where the streets smell like cheese: Milwaukee tries dairy waste as de-icer

In response to the winter storm striking the area last weekend, street crews of Milwaukee, a city in Wisconsin, will be spreading cheese brine(卤水)along its ice-covered streets this winter as an alternative of normally used rock salt, which serves as an essential road de-icer despite its damaging impact on the environment.

The trial was inspired by a successful experiment in rural Polk County. In addition to being a more effective de-icer due to a lower freezing point, the cheesy liquid prevents rock salt from bouncing and scattering off roadways, which means less has to be used and less of it ends up entering the surrounding environment.

Milwaukee can make good use of the difficult-to-dispose type of organic waste found in great abundance across the state: salty leftover cheese-making juice. Sometimes you just have to get creative and work with the type of waste byproduct and turn it into something beneficial. When the first cheese brine salt trucks of the city appeared in the street last week, Tom Barrett, Mayor of Milwaukee, compared the act to “thinking outside of the cheese box”.

To be clear, Milwaukee won’t completely replace rock salt with thousands of gallons of salty cheese juice. The project, which will first be tested in Bay View neighborhood, will involve a mixture of rock salt and cheese brine. The brine will be sourced from a production plant owned by F&A Dairy in Polk County. Milwaukee will save in rock salt costs while F&A Dairy, which transforms 900, 000 pounds of milk into cheese every day, will save cash in the brine disposal.

While it is noted that the cheese brine solution has a “distinctive odor.” Emil Norby, the gentleman who originally thought of using cheese brine to treat ice-covered roads, explains that Milwaukee residents can expect to experience the slight bad milk smell once the cheese brine is applied to streets. He smiles, “I don’t really mind it. Our roads smell like Wisconsin!”
