Every year, beer breweries discard thousands of tons of surplus yeast. Researchers from MIT and Georgia Tech have discovered an innovative method to repurpose this yeast to absorb lead from contaminated water.
Using a process known as biosorption, yeast can quickly absorb even trace amounts of lead and other heavy metals from water. The researchers have demonstrated that yeast can be encapsulated within hydrogel capsules to create an effective filter for removing lead. These capsules allow for easy removal of the yeast once the water is purified.
