Diesel Exhaust Converted Into Ink by Indian Innovators To Battle Air Pollution

Supervised by young engineers, workers at the start-up company Chakr Innovation in New Delhi cut and weld sheets of metal to make devices that will capture black plumes of smoke from diesel generators and convert it into ink.

Supervised by young engineers, workers at the start-up company Chakr Innovation in New Delhi cut and weld sheets of metal to make devices that will capture black plumes of smoke from diesel generators and convert it into ink.

In a cabin, young engineers pore over drawings and hunch over computers as they explore more applications of the technology that they hope will aid progress in cleaning up the Indian capital’s toxic air – among the world’s dirtiest.

While the millions of cars that ply Delhi’s streets are usually blamed for the city’s deadly air pollution, another big culprit is the massive diesel generators used by industries and buildings to light up homes and offices during outages when power from the grid switches off – a frequent occurrence in summer. Installed in backyards and basements, they stay away from the public eye.

“Although vehicular emissions are the show stoppers, they are the ones which get the media attention, the silent polluters are the diesel generators,” says Arpit Dhupar, one of the three engineers who co-founded the start up.

The idea that this polluting smoke needs attention struck Dhupar three years ago as he sipped a glass of sugarcane juice at a roadside vendor and saw a wall blackened with the fumes of a diesel generator he was using.

It jolted him into joining with two others who co-founded the start-up to find a solution. Dhupar had experienced first hand the deadly impact of this pollution as he developed respiratory problems growing up in Delhi.

A new business

As the city’s dirty air becomes a serious health hazard for many citizens, it has turned into both a calling and a business opportunity for entrepreneurs looking at ways to improve air quality.

According to estimates, vehicles contribute 22 percent of the deadly PM 2.5 emissions in Delhi, while the share of diesel generators is about 15 percent. These emissions settle deep into the lungs, causing a host of respiratory problems.

After over two years of research and development, Chakr has begun selling devices to tap the diesel exhaust. They have been installed in 50 places, include public sector and private companies.

The technology involves cooling the exhaust in a “heat exchanger” where the tiny soot particles come together. These are then funneled into another chamber that captures 70 to 90 percent of the particulate matter. The carbon is isolated and converted into ink.

Among their first clients was one of the city’s top law firms, Jyoti Sagar Associates, which is housed in a building in Delhi’s business hub Gurgaon.

Making a contribution to minimizing the carbon footprint is a subject that is close to Sagar’s heart – his 32-year-old daughter has long suffered from the harmful effects of Delhi’s toxic air.

“This appealed to us straightaway, the technology is very impactful but is beautifully simple,” says Sagar. Since it could be retrofitted, it did not disrupt the day-to-day activities at the buzzing office. “Let’s be responsible. Let’s at least not leave behind a larger footprint of carbon. And if we can afford to control it, why not, it’s good for all,” he says.

At Chakr Innovation, cups, diaries and paper bags printed with the ink made from the exhaust serve as constant reminders of the amount of carbon emissions that would have escaped into the atmosphere.

There has been a lot of focus on improving Delhi’s air by reducing vehicular pollution and making more stringent norms for manufacturers, but the same has not happened for diesel generators. Although there are efforts to penalize businesses that dirty the atmosphere, this often prompts them to find ways to get around the norms.

Tushar Mathur who joined the start up after working for ten years in the corporate sector feels converting smoke into ink is a viable solution. “Here is a technology which is completely sustainable, a win-win between businesses and environment,” says Mathur. (VOA)

India Says Pakistan’s Links with Pulwama Attack Clear For All to See

He said while there are claims to offer dialogue from Pakistan, it continues to shelter terror outfits

India has rejected Pakistan Foreign Secretary Tehmina Janjua’s claims denying her country’s links to the Pulwama terror attack, saying that JeM, which claimed responsibility for the attack on Thursday, is based in Pakistan, and the “links are clear and evident and for all to see”.

The External Affairs Ministry spokesperson on Friday termed as “preposterous” the demand for an investigation, saying there is a video of the suicide bomber declaring himself a member of the terror group Jaish-e-Mohammed (JeM).

The spokesperson said India has not seen any constructive approach from Pakistan on bilateral relations and it has been sheltering terrorists and terror organisations such as JeM. He said Islamabad has not taken any action against such groups despite international demands.

India also demanded that Pakistan take immediate and verifiable action against terrorists and terror groups operating from territories under its control to create a conducive atmosphere in the region free of terror.

The spokesperson’s response came over Pakistan Foreign Secretary’s briefing rejecting Pakistan’s involvement in the terror attack on a paramilitary convoy in Jammu and Kashmir that killed at least 45 troopers. Janjua met envoys of P-5 countries late on Friday.

The spokesperson said JeM has claimed responsibility for the attack.

The Ministry of Foreign Affairs said in a statement that the attack was a matter of “grave concern” and it had been condemning “heightened acts of violence in the (Kashmir) Valley”. Pixabay

“The organisation and its leadership are located in Pakistan. LeT and other terror groups have welcomed the news of the attack. These groups are also based in Pakistan. Pakistan cannot claim that it is unaware of their presence and their activities.

“They have not taken any action against these groups despite international demands, especially against groups and individuals proscribed by the UN and other countries. The links to Pakistan are clear and evident for all to see. Its own Ministers have shared the same podium with UN proscribed terrorists,” the spokesperson said.

He said there was audio-visual material linking JeM to the terror attack.

“The demand for an investigation is preposterous when there is a video of the suicide bomber declaring himself a member of the JeM. There are also other audio-visual and print material linking JeM to the terrorist attack. We have therefore no doubt that the claim is firmly established,” the spokesperson said.

He said while there are claims to offer dialogue from Pakistan, it continues to shelter terror outfits.

“We have not seen any constructive approach from Pakistan on relations with India. What we have noticed however, are claims to offer dialogue on the one hand, while sponsoring and sheltering terrorists and terrorist organisations such as JeM on the other,” the spokesperson added. (IANS)
