Delhi initiates Smog-devouring Road Tests

In an attempt to find more ways to curb air pollution, Delhi has launched a time-limited feasibility discussion to investigate the implementation of photocatalytic surfaces on roads, pavement, and public areas. The government envisages trial of titanium dioxide (TiO2) based surfaces capable of decomposing toxic substances such as nitrogen dioxide (NO2) and hydrocarbons under sunlight. An MOU with a scientific institution will be signed by the Environment Department not exceeding 30 days after which field tests, appraisals, and monthly progress reports will be provided. The ultimate report should be presented six months upon the signing of MoU.

The principle of operation of Photocatalytic Coatings.

Photocatalytic thin films are based on the TiO2 to initiate such chemical reaction as photocatalysis. The stimulant to the coating is sunlight, which enables the coating to transform toxic gases to less hazardous compounds. Such coatings might be applied on asphalt, concrete and other urban surfaces. They are stable, cost-effective, and passive-capable, which makes them appropriate to the implementation over the city in large quantities.

Government's Approach

The Environment Minister of Delhi highlights the practical science based solutions, which make sense and are quantifiable. The paper shall also be an evaluation of effectiveness, safety and cost effectiveness of the coatings. In case it succeeds, there will counter a citywide implementation involving high roads and markets, as well as the common place. The process is an extension of a 365 3-year ecological activity plan, which will cut pollution with ecological technology and use of scientific innovations.

Scientific and Technical Conceptions.

Scholars affirm the fact that TiO2 finishes can be applied to the conventional building materials. Suppliers will as well be evaluated in the study to facilitate quality and sustainability. Monitoring will avoid unwanted impacts. Also, the government is championing student, startup, and researcher opportunistic movements with an aim of speeding up pilot projects and carrying out complementary solutions.

Potential Impact

In case of proving that a photocatalytic-coating can be effective, the state of applying the coating passively, even continually, and to a considerable degree enhancing the quality of air can become possible. This technology could also decrease the respiratory health hazards through a cutback of smog and other polluters and enhance densities in cities. Such a long term deployment would be an addition to the existing pollution control mechanisms that would offer cleaner and healthier environment to the residents of Delhi.

The effort is the first step in a sensible and scientific technology-oriented work towards solving one of the most burning environmental problems, which affect India, and that other congested cities in the country will emulate.
