This IIT Guwahati Innovation Cleans Toxic Wastewater Without Harsh Chemicals

Lead pollution is one of India's most overlooked public health crises. According to a 2020 UNICEF and Pure Earth report, India is home to over 275 million children with elevated blood lead levels, nearly half the country's child population.  A major source of this contamination is wastewater from battery recycling units, which often carries high concentrations of dissolved lead into rivers and soil. Now, researchers at the Indian Institute of Technology (IIT) Guwahati have developed a biological process that could offer a cleaner way to deal with this problem. Instead of relying on chemical...
