A circular economy for salt that keep rivers clean
Solution for rivers polluted by salt.
This woman had lived along the Mississippi river most of her life and explained the importance of protecting the rivers from pollution, more specifically, salt. Her proposition had three parts but the most interesting one for me was the circle of salt. Instead of mining more and more salt for industry and roads, we can simply reuse it. We can capture the runoff and put it through a series of membranes in order to reuse the salt and keep the water free of it.
