Air pollution is one of the biggest environmental and human health threats in the world, according to a 2016 World Health Organization report:
“To date, air pollution – both ambient (outdoor) and household (indoor) – is the biggest environmental risk to health, carrying responsibility for about one in every nine deaths annually. Ambient (outdoor) air pollution alone kills around 3 million people each year…Air pollution continues to rise at an alarming rate and affects economies and people’s quality of life; it is a public health emergency.”
Engineer Anirudh Sharma was familiar with the problem. The MIT Media Lab student was walking down a street in Mumbai, reported, when he noticed that diesel exhaust from passing buses and cars was staining his clothes black.
The experience sparked an idea: Was it possible to recycle air pollution and use it to make something useful? Like ink?
During the past few years, Sharma has developed technology to create the world’s first line of art supplies derived from air pollution. He and his team have built an exhaust filter that captures carbon soot as it is emitted from cars, generators, and ferries. Once pollution has been gathered, impurities are removed. The remaining soot is ground into pigment and mixed with vegetable oil to create inks, markers, and paints.
One artist commented, “I don’t know if it’s the pollution, but the quality of the ink is really special…It’s pitch black, really thick and dries incredibly quickly.”
Last month, the first Clean Air Gallery opened in London. It features work by artists from London, Glasgow, Leeds, Southampton, and Nottingham – some of the most polluted cities in the United Kingdom – using Sharma’s ink. Other exhibitions are expected to open in Berlin, Singapore, and New York.
