A circular economy for salt that keeps rivers clean

Combining science, circular thinking & disruptive innovation to preserve water sources

During the winter of 2018-2019, one million tons of salt were applied to icy roads in the state of Pennsylvania alone. The salt from industrial uses like this often ends up in freshwater rivers, making their water undrinkable and contributing to a growing global crisis. 

Tina Arrowood understands that water is the world’s most valuable resource — and one of the most finite. How can we better protect these precious natural resources? Physical organic chemist shares a three-step plan to keep salt out of rivers — and create a circular salt economy that turns industrial byproducts into valuable resources.
