- India’s first microalgae-based air tower was installed in New Delhi to reduce air pollution from vehicles.
- The tower is set up near the Aerocity highway as a pilot project to test new pollution control technology.
- It uses microalgae and photosynthesis to absorb pollutants like carbon dioxide, nitrogen oxides and particulate matter.
- Polluted air is taken into the tower and converted into oxygen and algal biomass naturally.
- It is a nature-based and sustainable method for improving urban air quality.
