One person’s wastewater is another person’s treasure. A new Stanford University study paves the way to mining sewage for valuable materials used in fertilizers and batteries that could someday power smartphones and airplanes. The analysis, published recently in ACS ES&T Engineering, reveals how to optimize electrical processes for transforming sulfur pollution, and could help lead to affordable, renewable energy-powered wastewater treatment that creates drinkable water.
