Cellulose sponge

Caption

The sponge, coated with nanoparticles that have an affinity for pollutants, can collect metals like zinc and copper, as well as phosphate, and in previous iterations has successfully pulled lead from water, and microplastics and oil from lakes and oceans. It then releases these valuable resources when it is exposed to different pH’s.
