How IIT-Delhi is trying to combat air pollution with tech solutions

The Indian Institute of Technology, Delhi (IIT-Delhi) has devised technological solutions to combat air pollution in the country. With the establishment of Centre of Excellence for Research on Clean Air (CERCA) in February 2018, the institute has come up with devices to control polluted air.

The cost-effective devices, as per a release by IIT-Delhi, can provide temporary relief from air pollution in the national capital and other states of north India. One such device, the Chakr Shield, helps to convert pollutants to ink that can be used for drawings. The retrofit device by the IIT Delhi alumni can trap 90 percent of particulate matter in the exhaust, thus reducing the pollution caused by the diesel generators.
