flag IIT Guwahati scientists created a low-cost, eco-friendly method using cyanobacteria to remove 92.5% of lead from water, with plans to scale it for real-world use.

flag Researchers at IIT Guwahati have developed a low-cost, eco-friendly method to remove lead from water using cyanobacteria, specifically Phormidium corium NRMC-50, which absorbs lead efficiently under sunlight. flag The technique, which uses natural biopolymers and requires minimal resources, achieved 92.5% lead removal in lab tests and may also capture other pollutants. flag The process could reduce treatment costs by 40–60% compared to conventional methods and allows for metal recovery for reuse in products like biochar or bioplastics. flag The team is now scaling the technology from lab to pilot testing in real wastewater systems.
