Wisconsin has a history of cheese production, but did you realize that they plan to use it to de-ice the roads in the winter?
Well, not exactly the cheese, but the cheese brine. Currently, they use rock salt to maintain the roads during the winter. Someone got the idea to take the brine, the waste used when making the curds, and use this salty mixture on the roads rather than just disposing of it. This process doesn't eliminate the use of salt on the roads, but severely reduces the amount needed.
Polk county has been doing this for four years and has reduced the salt usage by 30%. Milwaukee is further south and expects to have better results. They'll create a pilot program this winter and monitor the results. Let's hope is Gouda.
