Brine from pickling foods helps tremendously with melting snow and ice. According to the National Geographic, pickle brine is better for the environment (than salt) because it prevents ice from sticking to the road, making it easier to remove. Using pickle brine in place of rock salt on the streets also means up to 29% less chloride added to our water systems. When used as a pre-treatment before snowfall, pickle brine prevents snow & ice from bonding to the pavement. The ice is then easily chipped off and removed, which is something that rock salt won’t do alone.
Bergen County in New Jersey faced a salt shortage in 2011 due to budget cuts. Forced to come up with a new plan-of-attack, pickle brine was their solution. The salty green liquid was sprayed on the roads and sidewalks as an experiment. It turned out to be waste-effective, because there is plenty of the stuff being discarded from factories and homes all the time. What’s more, using pickle brine is cost-effective at just 7 cents per gallon. This alternative is as effective, less expensive, and more environmentally friendly than using salt.
