How Technology can be used to Tackle Pollution


Recently, the air pollution in New Delhi has been the talk of the town. Various factors contribute to this. Vehicle emissions in New Delhi are the prime reasons behind the creation of smog around the city. The National Environmental Engineering Research Institute (NEERI) and The Central Pollution Control Board (CPCB) have declared this to be the major reason behind air pollution in New Delhi. With more population, the pollution levels increase as the demands and uses of people increase and the capital of India is well known for being overpopulated. Along with being known for lack of proper infrastructure, Delhi is known for incomplete infrastructure projects. Delhi Government has stalled the construction activities in and around Delhi NCR for the fact that it was the second major contributor towards New Delhi’s air pollution. Delhi has a lot of industries and industrial pollution also contributes to air pollution. Badarpur Thermal Power Station produces 80 to 90% of the particulate matter pollution from the electric power sector in Delhi.

How Technology can be used to Tackle Pollution

To curb this, a myriad of technological solutions can be implemented. Introduction of monitoring devices using optical particle counters and optical sensors can be one of the solutions. Optical particle counters detect particulate pollution by measuring the light scattered by particles. Optical sensors detect gases like carbon monoxide and carbon dioxide by measuring the absorption of infrared light. Using these devices in vehicles can help in monitoring three air pollutants viz., Sulphur Dioxide (SO2), Nitrogen Dioxide (NO2) and Particulate Matter size equal to or less than 10 micron (PM10) which contribute to air pollution. Vehicles can get an alert if the emissions exceed the specified levels and defaulters failing to abide by the ideal levels of particulate matter can be penalized.

Installing particulate matter monitoring devices near traffic signals and in the vicinity of industries can be promoted. At the traffic signals, a proper calculation and display of particulate matter in the air can be calculated and displayed by sensors and this can be used as a method to increase awareness among the citizen. Such devices near industrial regions can help monitor the emissions from industries and then they can be kept in check.

The Indian Government is trying to switch to an initiative of all-electric cars by 2030. This initiative will not only curb the issue of vehicular emissions of particulate matter, but it will also address the issue of rampart air pollution in high-end metros like New Delhi. Electric vehicles (EVs) are steadily gaining traction, thanks in part to favorable government initiatives and the entry of international players like Honda, Suzuki, Ford, Toyota, Volvo and Hyundai as well as startups such as Ather Energy, ION Energy, Ultraviolette Automotive, among others.

Technology today has grown by leaps and bounds and a problem which is as pestering as pollution levels in cities can be easily curbed by the use of technology. Thus, it is only wise at this stage of time that technology is implemented so as to address the burning environmental issues.
