Smog eating coating to decrease The Great Smog of Delhi
In 2011, a New York based company, Arconic, launched the first smog eating coating for windows called “EcoClean”. This is a special type of nano coating that helps buildings self-clean and purify the surrounding air. The smog eating coating offers a number of benefits over traditional glass windows, such as, improving the looks, maintenance benefits and reduces pollution in the air. Due to the problems of smog and the health issues that come with the smog in Delhi, this smog eating coating can be one of the greatest solutions for Delhi.
The technology behind smog eating coating
The smog eating coating of EcoClean has titanium dioxide in it. If titanium dioxide is exposed to sunlight, electrons are activated and start breaking down organic particles and at the same time it creates a water-loving surface, also known as hydrophilic. Organic contaminants are sometimes invisible to the eye. One of the major pollution particles in the air that creates smog is nitrogen oxides. Nitrogen oxides particles have a negative effect on the air quality and therefore, dangerous to breath in. One of the major problems in Delhi at the moment. EcoClean’s smog eating coating converts dangerous nitrogen oxides to harmless nitrate. The activated electrons react with water and oxygen in the air to fight the nitrogen oxides and by doing so, the coating purifies the air.
Besides that titanium dioxide brakes down the organic contaminants and converts the nitrogen oxides, it has one more major benefit for the building on which it is applied. Namely, EcoClean’s smog eating coating is super hydrophilic. The coating attracts water particles in the air, creating a cleaning shower for the building, bringing down all the broken-down organic contaminants.
The great smog of Delhi
During the winter seasons, New Delhi has to cope with heavy winter smog. After the Diwali festival in October and the start of the winter of 2017 in India, inhabitants need to cope with air pollution. Before the Diwali Festival, the government shut down a coal-fired power plant and using privately-owned diesel generators in New Delhi was not allowed. Besides that, selling the popular firecrackers that are used during the Diwali festival were temporary forbidden as well. Desperately trying to reduce the air pollution or at least try to stop the growth of it.
What causes the air pollution in Delhi
In order to solve the problem the causes of the dense smog, that takes over Delhi every winter, need to be clarified. All the causes cannot be eliminated immediately and the power to start improving the air quality in Delhi lies with the inhabitants and the authorities. However, smog eating coating might be a great idea to decrease the amount of smog and air pollution in Delhi. Besides the firecrackers used during the festival, the transportation in Delhi, heaters used in the winter season and the massive amount of crop waste that is burned after the crop season are causing the air pollution in Delhi.
The Central Pollution Control Board gathers data about India’s air pollution and smog on a daily basis.
Benefits of smog eating coating for Delhi
So what could this smog eating coating mean for The Great Smog of Delhi?
- When applied it does not need to be applied again, it is a life-long coating
- Reduces the amount of Nitrogen Oxides (NOx) in the air with 5.5 milligrams per m2 per day
- Has self-cleaning properties and therefore easy to maintain
- The original paint of the building is not attacked by the coating
- Due to the decrease of smoke, the health issues in Delhi can decrease as well.
