Co-founders of Graviky Labs in Bangalore, India, Anirudh Sharma and Nikhil Kaushik have come up with a way to utilize soot prevalent in densely populated urban areas. Kaalink is a soot trap that can be attached to the tailpipe of vehicles, and is able to capture up to 95 percent of pollutants. The harmful soot is "then ground into an ultrafine powder and combined with solvents and oils to produce five grades of ink for a variety of applications, from screen printing to oil painting," according to the Wired article. Thus, AirInk is formed.

Though the duo do not believe this is the sole answer to the issue of air pollution, they hope to use it to at least reduce toxicity in the air we breathe.
