Tiger Beer launched a special kind of ink made from recycled air pollution. Together with Graviky Labs in Bangalore they spent 3 years designing a device capturing soot from all kind of vehicles' exhausts. These devices were placed on boats, cars, chimnies all around Hong Kong and India
They made over 150 litres of Air-Ink approximating to 2500 hours worth of typical diesel car emissions. This special ink was then given to 9 street artists in Asia, who made spectacular murals.
