Air-Ink – Converting air pollution into ink
Air pollution is an environmental hazard that is taking a toll on each and every person’s life. A major source of air pollution is the emission of hazardous fumes from vehicles. Diseases affecting the lungs are on the rise.
Gaviky Labs has developed an ingenious method to reduce air pollution by recycling the soot emitted through the exhaust fumes of vehicles. Soot is composed of fine black particles, mainly carbon, produced by incomplete combustion of fossil fuels. Researchers at the MIT Media Lab have come up with Air-Ink which literally captures pollution from air and converts it into ink. This ink is used in a variety of art products.
The process makes use of a device called Kaalink which is retrofitted to the exhaust pipe of vehicles to capture the soot emitted. The soot which is collected is passed through various processes to remove heavy metals and carcinogens. This results in a purified carbon based pigment which in turn is used to make different types of inks and paints.
Air-Ink is currently available as 2 mm, 15 mm, 30 mm and 50 mm markers which are water resistant, and as 150 ml of screen printing ink through Kickstarter project. Using 30 ml of Air-Ink would mean confining 45 minutes worth of pollution.
