**Delhi to Test ‘Smog-Eating’ Coatings on City Infrastructure**
*By Snehil Singh | Sep 22, 2025, 08:30 PM*
The Delhi government has launched a feasibility study aimed at deploying innovative “smog-eating” coatings on the city’s infrastructure to combat hazardous air pollutants through scientific and technology-driven solutions.
**Exploring Photocatalytic Surfaces**
Environment Minister Manjinder Singh Sirsa announced that the government will explore the application of photocatalytic surfaces containing titanium dioxide (TiO₂). These coatings can be applied to roads, pavements, and public spaces, where they work to break down harmful pollutants in the air.
**Evaluation Process Underway**
To kickstart the initiative, the Environment Department has been tasked with signing a memorandum of understanding (MoU) with a reputed scientific institution within the next 30 days. This MoU will initiate a six-month period of field trials and evaluation.
During the evaluation phase, the department will provide monthly progress reports and is expected to submit a comprehensive final report within six months of signing the MoU.
**Measuring Pollution Reduction and Sustainability**
The study will focus on assessing the effectiveness of the titanium dioxide coatings in reducing air pollutants such as nitrogen dioxide and harmful hydrocarbons. In addition to pollutant breakdown, the research will evaluate the cost-effectiveness, safety, and long-term sustainability of the technology.
Minister Sirsa emphasized that this effort represents a practical step towards delivering tangible improvements for Delhi’s residents. “We are putting simple, safe, science-based tools on the ground and measuring results openly,” he stated.
**Potential for Rapid Citywide Deployment**
Should the study demonstrate positive outcomes regarding efficiency and cost, the government plans to rapidly deploy these “smog-eating” surfaces citywide. Priority will be given to high-traffic corridors, busy markets, and major public spaces.
The titanium dioxide technology is low-cost, chemically stable, and compatible with traditional construction materials, making it an ideal candidate for large-scale urban application.
**A Comprehensive Environmental Strategy**
This initiative forms part of Delhi’s year-round strategic environmental action plan, designed to strengthen the city’s defense against air pollution through scientific validation and technology-driven interventions.
In addition, the Environment Department has launched an “Innovators’ Challenge,” inviting ideas from students, startups, and experts to pilot other promising air quality technologies rapidly.
Minister Sirsa reaffirmed Delhi’s commitment to evaluating and adopting proven photocatalytic solutions with a focus on safety, sustainability, and measurable impact.
