Delhi’s government is stepping up its battle against air pollution with a new study on “smog-eating” photocatalytic coatings. These special treatments can go on roads, concrete, and tiles to break down harmful NO2 gases and hydrocarbons, helping clean the air we breathe. Environment Minister Manjinder Singh Sirsa shared the news on Sunday.
Sirsa has ordered the Environment Department to create an action plan that uses cutting-edge technology and solid science to build a stronger defense against Delhi’s smog woes. “We’re evaluating the best proven photocatalytic technologies out there,” Sirsa said. “We’ll focus on safety, sustainability, and real results to bring cleaner air to the city faster.”
For many in Delhi, the fight against pollution hits close to home—think kids playing outside, seniors enjoying the day, or workers heading to jobs. “This is personal,” Sirsa added. “We’re rolling out simple, safe tools backed by science. We’ll measure the impact openly and scale up what works, so families notice fresher air right away.”
The department will handle this in clear, straightforward steps. First, they’ll pick a trusted scientific partner within 30 days. Then, they’ll test the coatings on actual city streets. Expect monthly updates on progress, with a full report ready in six months after signing the agreement.
The study will zero in on safety, eco-friendliness, and bang for the buck. They’ll also scout reliable suppliers to make scaling up easy if the results impress. If these smog-eating surfaces prove effective and affordable at cutting NO2 and pollution, Sirsa plans to push for a cabinet approval to roll them out across busy spots like roads, markets, and public areas. That means quick wins for better air quality where people need it most.
The department gets the green light to add any practical details for smooth rollout, always putting citizens first in every choice.
Sirsa also highlighted the Innovators’ Challenge as a key way to spark community-driven fixes for air pollution in Delhi. “We’ve supported innovation from the start to tackle real problems on our streets,” he said. The challenge has pulled in students, startups, and experts, with the department now picking top ideas for fast trials and checks. “Share your best concepts,” Sirsa urged. “We’ll test them, fund the winners, and expand what succeeds—so every family in Delhi can breathe a little easier.”
