IIT graduate Kharagpur develops device to stop air pollution

NEW DELHI: A graduate of IIT Kharagpur has invented a device called PM 2.5 that, according to him, was placed near the muffler pipe in vehicles to curb air pollution.

Debayan Saha, a mechanical engineering graduate from IIT Kharagpur, who invented the device, says a car equipped with the device can neutralize the pollution emitted by 10 cars in its vicinity.

The technology developed by us uses a combination of electric energy and wave energy to influence pollutants such as PM 2.5 so that they act as a magnet that attracts other particulate pollutants from the ambient atmosphere to adhere to it. As they grow in size, they become heavy and fall safely on the ground like soil, said Saha, who was also a researcher at AIIMS and worked on air pollution.

A car on the street can now relieve pollution in its immediate surroundings and potentially neutralize the pollution emitted by 10 cars in its vicinity. When they really immersed themselves in the problem, they found that the main culprit is not PM-2.5 but its small size because it can easily enter our lungs and bloodstream, he said.

Saha, is in talks with several organizations to market the product.

A layer of toxic mist covered the region of the national capital on Wednesday, as air quality in Delhi and adjacent areas fell to very poor levels, affecting visibility and causing residents discomfort.

The Delhi government attributed the drop in air quality to the burning of unbridled stubble in neighboring states, a common feature in October-November.

The period between October 15 and November 15 is considered critical, since the maximum number of incidents of stubble burning occurs in this period in Punjab and the adjacent states, and is one of the main reasons for the alarming increase of pollution in Delhi-NCR.
