Pollution turned into clean ink

Street art made from ink from air pollution is helping beautify cities around the world. The Air-Ink device captures air pollution from diesel exhausts before it enters the atmosphere, which is then turned into ink for artists. Since its launch in 2016, more than 770 litres of Air-Ink has been harvested. “Growing up in India and experiencing the effects of air pollution first-hand motivated me to think of ways to turn this harmful pollution into something useful – purified, safe ink,” says Air-Ink inventor Anirudh Sharma.
