How a circular salt economy could protect our freshwater rivers
In short: In Pennsylvania alone, one million tons of salt were used on icy roads during the 2018-2019 winter. This video explores how industrial salt runoff threatens drinking water and presents a plan to transform waste into resources.
Physical organic chemist Tina Arrow and her proposed three-step strategy aims to prevent industrial salt from polluting freshwater rivers. The runoff from large-scale applications, such as the massive amounts used for road maintenance, contributes to a global water crisis by making river water undrinkable. The presentation focuses on creating a circular economy that repurposes industrial byproducts into valuable materials rather than letting them become environmental pollutants.
