Anirudh Sharma: Ink made of air pollution

Ink made of air pollution

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.

Millions die each year from outdoor air pollution, much of it made up of invisible PM 2.5 particles that damage our lungs. By capturing soot from diesel engines and generators, innovators have started transforming this waste into deep black ink. What began as a homemade experiment has grown into a global movement, with artists using ink made from recycled pollution to create striking works. This approach reframes pollution as a resource and suggests creative new ways to tackle environmental problems.
