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 Continues Engaging With USA Over H-1B Passport Issue

India is closely engaged with the US administration as well as the US Congress on this matter.

As Trump proposes changes in H1-B visa, India continues to engage with US

India is continuing to engage with the US over the H-1B visa, largely availed of by Indian IT companies, after the Trump administration proposed changes to the programme, a senior official said on Thursday.

“It is a very important topic for us and that is the reason why we have time and again at various levels, we have taken up this matter with the US side,” External Affairs Ministry spokesperson Raveesh Kumar said in response to queries by journalists here.

Kumar said that most recently, the issue was raised during the first ever India-US 2+2 Ministerial Meeting held here last month that was attended by External Affairs Minister Sushma Swaraj, Defence Minister Nirmala Sitharaman, US Secretary of State Mike Pompeo and Defence Secretary Jim Mattis.

On Wednesday, the US Department of Homeland Security (DHS) said that the US Citizenship and Immigration Services (USCIS) plans to come out with its new proposal by January 2019.

The DHS said it was also proposing to remove from its regulations certain H-4 spouses of H-1B non-immigrants as a class of aliens eligible for employment authorisation.

The move to end the rule could have an impact on more than 70,000 H-4 visa holders, who have work permits.

The H-4 visas are issued by the USCIS to immediate family members (spouse and children under 21 years of age) of the holders of H-1B visa.

The DHS said it will propose to revise the definition of speciality occupation to increase focus on obtaining the best and the brightest foreign nationals via the H-1B programme.

It will also “revise the definition” of employment and employer-employee relationship to “better protect” US workers and wages, the DHS said.

In his remarks on Thursday, Kumar said that India is closely engaged with the US administration as well as the US Congress on this matter.

Stating that there are certain bills which have been introduced, he, however, said that “it is important to note that none of these bills have been passed so far”.

“When we have engaged with the US, we have emphasised that our partnership which we have in the digital sphere have been mutually beneficial,” the spokesperson said.

“We have highlighted the role which has been played by the highly skilled Indian professionals who have actually contributed to the growth and development of the US economy,” he stated.

“And also they have helped the US to maintain a competitive edge in the world towards innovation and science and technology.” (IANS)
