A pilot project using algae to filter pollutants has been launched at Anand Vihar in Delhi, aiming to improve air quality.
Delhi’s chronic air‑pollution problem has prompted officials to trial an innovative solution at the Anand Vihar hub. The pilot uses specially cultivated algae that absorb harmful particles and gases, effectively acting as a living filter for the surrounding atmosphere.
The experimental setup involves installing algae‑filled bioreactors at strategic points within the Anand Vihar complex. As the algae photosynthesize, they capture nitrogen oxides, particulate matter and other common pollutants, releasing cleaner air back into the environment.
Authorities say the trial will run for several weeks, during which air‑quality sensors will monitor changes in pollutant levels. If the results prove positive, the technology could be expanded to other high‑traffic zones across the capital.
Environmental experts note that algae‑based purification offers a low‑energy, sustainable alternative to conventional filtration methods, though its effectiveness in dense urban settings remains to be fully evaluated.
The initiative reflects Delhi’s broader push to adopt green technologies as part of its strategy to meet national air‑quality standards and protect public health.
