What if we could capture pollution in the air around us and turn it into something useful? Inventor Anirudh Sharma shares how he created AIR-INK, a deep black ink that's made from PM 2.5 pollution. See how he hacked together a clever way to capture these tiny particles -- and make the world just a little bit cleaner in the process.

Harnessing air pollution to create AIR-INK: turning PM 2.5 particles into high-quality, sustainable ink for art and writing.

A retrofit technology captures emissions directly from diesel engines, preventing pollutants from entering the atmosphere.

From lab experiment to global art: AIR-INK transforms pollution into a medium for artists, reducing environmental impact.
