A new chemical treatment turns deadly arsenic-rich groundwater waste into useful raw materials. A two-step process converts the hazardous sludge into a raw material for electronics, batteries and semiconductors. The process is still at the lab scale, and the key challenge for scaling up the technology is developing the most cost-effective and efficient method of operating.
