Air Ink by Graviky and Tiger Beer

Tiger Beer, in collaboration with MIT-spinoff Graviky Labs and agency Marcel Sydney, has launched Air-Ink; an innovative range of pens, markers and spray cans made from air pollution.

To create Air-Ink, unique devices were developed to capture soot from vehicles' exhausts. These were fitted to trucks, ferries, chimneys and even cranes around Hong Kong and India. The captured pollutants were then purified and turned into safe, reliable ink for everyday use.
