In Wisconsin winters, you can drive on a cheesy road to get your cheesy bread and cheese pizza!
The state, affectionately known as America’s dairyland, looked to its cheesemakers for help in keeping the roads clear in the winter. According to NPR, Wisconsin has been experimenting with using waste from cheese production for its roads for some time. Liquid cheese brine, used to salt wheels of cheese, is mixed with rock salt once it’s done with at the dairy plant.
Sounds like a good use of what has been traditional waste, but one does have to wonder... Do the roads smell like cheese when applied?
As well as making use of a waste product, there are practical benefits of using cheese brine to clear roads. According to NPR, the solution helps salt stick to the road, rather than bouncing off into the hard shoulder. It has also been found to speed up the melting of ice and snow that falls onto roads, as well as saving the state thousands of dollars in rock salt orders every year.
