Pollution paint

Air pollution is the scourge of many bustling East Asian metropolises, but Tiger Beer has turned it into a potential resource called Air-Ink. Working with Indian entrepreneur and MIT Tech Review’s Innovator of the Year, Anirudh Sharma, the drinks brand has neutralised pollution and unleashed creativity.

The carbon-rich soot is harvested through a convertor that can be easily attached to exhaust outlets before being processed and decanted into safe ink. So far, Tiger has produced 150 litres of Air-Ink from sites in Hong Kong and Bangalore, which equates to roughly 2,500 hours of car emissions (or about 104 days of driving a Diesel vehicle). The Air-Ink was then given to well-known Hong Kong street artists such as Bao Ho and Kristopher H.
