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.

India to Set Up “Border Haats” with Myanmar

The Minister said, The success of the "Border Haats" running along the Bangladesh border in Meghalaya and Tripura has prompted us to go for similar 'haats'

The success of the “Border Haats” with Bangladesh has prompted other northeastern states of India to go for similar arrangements with Myanmar. At the instance of the Mizoram government, the Centre is likely to set up four “Border Haats” (market) along the border with Myanmar to boost local trade and livelihood of the people living there.

“To carry out border trade with Myanmar, the location for the construction of ‘Border Haat’ has been identified in four places — Hnahlan, Zote, Vaphai (Saikhumphai) and Sangau (Pangkhua) in southeastern Mizoram,” Mizoram Commerce and Industries Minister R. Lalthangliana told IANS.

The Minister said, “The success of the “Border Haats” running along the Bangladesh border in Meghalaya and Tripura has prompted us to go for similar ‘haats’ with Mynmar in Mizoram.”

Mizoram Commerce and Industries Department Director J. Hmingthanmawia said that the state government has sent the detailed proposals in this regard to the Ministry of External Affairs (MEA) for its approval.

“Once we get the green signal from the MEA, we would seek funds from the Union Industries and Commerce Ministry,” Hmingthanmawia told IANS. He said that officials of the Mizoram government and Myanmar have recently conducted a joint survey and identified the locations to set up the “Border Haats”.

Mizoram Chief Minister Zoramthanga in his Independence Day speech had said that the proposed “Border Haats” would become important trade points between India and Myanmar.

“Land Custom Station (LCS) at Zokhawthar, the lone trade route for Mizoram with South East Asian countries, is being proposed for upgradation. Construction of Trade Facilitation Centre at Tlabung has already been completed.”

“The Indian government has also proposed construction of an Integrated Check Post (ICP) at four places at the border in Mizoram — Marpara, Tuipuibari, Silsuri and Nunsury. The construction of ICP at Kawrpuichhuah is also expected to commence shortly,” the Chief Minister added.

Mizoram has an unfenced international border of 404 km with Myanmar and 318 km with Bangladesh. The Border Security Force (BSF) has been guarding the Bangladesh border and Assam Rifles personnel are posted on the border with Myanmar.

Experts and various studies suggest that if the “Border Haats” are set up, smuggling of drugs and other commodities would be checked to a large extent. Security expert Manas Paul said that large-scale smuggling of drugs from Myanmar via Mizoram and other neighbouring states has increased in the last few years.

“What is really worrisome is the fact that these synthetic drugs have got a domestic market inside the state, especially among the younger generation. Cross border legal activities including setting up of “Border Haats” could curb the smuggling of drugs and other contraband,” Paul, who has authored books on security and terrorism in the northeast, told IANS.

The CUTS International, a Jaipur based international NGO, with support from the World Bank, had conducted a study in 2016 to understand and examine the effect of “Border Haats” on poverty alleviation and other multiplier effects such as informal trade.

CUTS International Executive Director Bipul Chatterjee said that trade will increase income, curb smuggling, and cross-border crimes will also go down.

“‘Border Haats’ have contributed to the border area development, roads have improved, trafficking of women has stopped, unemployment issues have been addressed,” said Chatterjee.

Currently four “Border Haats” are operational in Meghalaya and Tripura. The first “Border Haat” was started on July 23, 2011 at Kalaichar (India)-Kurigram (Bangladesh) in the West Garo Hills of Meghalaya. Three other “haats” followed in Meghalaya and Tripura.
