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.

World’s Anti-Corruption Day

The U.S. Statement Department said in its Friday statement that it pledges "to continue working with our partners to prevent and combat corruption worldwide."

Corruption costs the world economy $2.6 trillion each year, according to the United Nations, which is marking International Anti-Corruption Day on Sunday.

“Corruption is a serious crime that can undermine social and economic development in all societies. No country, region or community is immune,” the United Nations said.

The cost of $2.6 trillion represents more than 5 percent of global GDP.

The world body said that $1 trillion of the money stolen annually through corruption is in the form of bribes.

Patricia Moreira, the managing director of Transparency International, told VOA that about a quarter of the world’s population has paid a bribe when trying to access a public service over the past year, according to data from the Global Corruption Barometer.

Moreira said it is important to have such a day as International Anti-Corruption Day because it provides “a really tremendous opportunity to focus attention precisely on the challenge that is posed by corruption around the world.”

Anti-corruption commitments

To mark the day, the United States called on all countries to implement their international anti-corruption commitments including through the U.N. Convention against Corruption.

In a statement Friday, the U.S. State Department said that corruption facilitates crime and terrorism, as well as undermines economic growth, the rule of law and democracy.

“Ultimately, it endangers our national security. That is why, as we look ahead to International Anticorruption Day on Dec. 9, we pledge to continue working with our partners to prevent and combat corruption worldwide,” the statement said.

Moreira said that data about worldwide corruption can make the phenomena understandable but still not necessarily “close to our lives.” For that, we need to hear everyday stories about people impacted by corruption and understand that it “is about our daily lives,” she added.

She said those most impacted by corruption are “the most vulnerable people — so it’s usually women, it’s usually poor people, the most marginalized people in the world.”

The United Nations Development Program notes that in developing countries, funds lost to corruption are estimated at 10 times the amount of official development assistance.

What can be done to fight corruption?

The United Nations designated Dec. 9 as International Anti-Corruption Day in 2003, coinciding with the adoption of the United Nations Convention against Corruption by the U.N. General Assembly.

The purpose of the day is to raise awareness about corruption and put pressure on governments to take action against it.

Tackling the issue

Moreira said to fight corruption effectively it must be tackled from different angles. For example, she said that while it is important to have the right legislation in place to curb corruption, governments must also have mechanisms to enforce that legislation. She said those who engage in corruption must be held accountable.

“Fighting corruption is about providing people with a more sustainable world, with a world where social justice is something more of our reality than what it has been until today,” she said.

Moreira said change must come from a joint effort from governments, public institutions, the private sector and civil society.

The U.S. Statement Department said in its Friday statement that it pledges “to continue working with our partners to prevent and combat corruption worldwide.”

It noted that the United States, through the U.S. Department of State and U.S. Agency for International Development, helps partner nations “build transparent, accountable institutions and strengthen criminal justice systems that hold the corrupt accountable.”

Moreira said that it is important for the world to see that there are results to the fight against corruption.

“Then we are showing the world with specific examples that we can fight against corruption, [that] yes there are results. And if we work together, then it is something not just that we would wish for, but actually something that can be translated into specific results and changes to the world,” she said. (VOA)
