NEW DELHI: The Delhi government will conduct a time-bound study on “smog-eating” photocatalytic coatings, a technology designed to neutralise harmful gases like nitrogen dioxide and volatile hydrocarbons that contribute to the capital’s toxic air, Environment Minister Manjinder Singh Sirsa announced on Sunday.
The project will focus on Titanium Oxide-based coatings, which can be applied to roads, pavements, and public spaces to reduce nitrogen dioxide and other harmful hydrocarbons.
Sirsa said the initiative aims to strengthen the city’s pollution-control measures through technology-driven interventions and scientific validation.
According to the plan, the Environment Department will sign a memorandum of understanding (MoU) with a reputed scientific institution within 30 days to carry out field trials. Monthly progress updates will be released, and a final study report is expected within six months of the MoU signing.
“If the study confirms that these smog-eating surfaces are effective and cost-efficient, a proposal will be moved before the Cabinet for rapid, citywide deployment at priority locations such as busy corridors, markets, and public spaces,” Sirsa said.
He added that the department will ensure safety, sustainability, and value for money while identifying credible suppliers for potential large-scale rollout. “This is about protecting Delhi’s people with solutions that work on the ground. We are putting simple, safe, science-based tools on the ground and measuring results openly so families feel the difference in the air they breathe and in their lives,” he said.
The government has also linked the initiative with its Innovators’ Challenge, inviting students, startups, and experts to propose practical anti-pollution solutions. Sirsa noted that several ideas have already been shortlisted for pilot testing. “Bring your best ideas—Delhi will test them, fund what works, and take it citywide so every family can breathe easier,” the minister added.
Officials said the study is part of a broader 24x7 strategic environmental action plan being implemented by the Delhi government to tackle pollution through innovation and evidence-based measures.
