Various innovative technologies aimed at mitigating air pollution have recently been tested with promising outcomes. The technologies under review include air purification units developed by the National Environmental Engineering Research Institute (NEERI) for traffic junctions, dust suppressants for construction sites and road dust control created by the Environmental Protection Research Institute (EPRI), bus rooftop filtration systems from Manav Rachna International Institute of Research & Studies (MRIIRS), a medium-scale air purification unit (SMOG TOWER) from IIT Bombay and Tata Projects Ltd, and ionization technology developed by the Science and Technology Park (S&TP) Pune.

Among these technologies, the results for the dust suppressant were particularly encouraging. Consequently, an advisory has been issued recommending its use in Delhi-NCR to address dust pollution.

The project summaries, including the sanctioned costs and expenditures for these initiatives, are detailed in Annexure-I.
