India’s first microalgae-based PureAir Tower has been installed in New Delhi along the Aerocity highway corridor to address rising vehicular pollution. The innovative biotechnology system uses photosynthetic microalgae to capture pollutants such as carbon dioxide, particulate matter and nitrogen oxides from the surrounding air. These pollutants are then converted into oxygen and algal biomass through natural biological processes. The project was developed through collaboration between C P Arora Private Limited and Carbelim Pvt Ltd, a climate-tech startup incubated at IIT Madras. The tower is designed to provide an air purification effect comparable to more than 15 mature trees, helping improve urban air quality sustainably.
