What if we could capture pollution in the air around us and turn into something useful? Inventor Anirudh Sharma shares how he created AIR-INK, a useable black ink that's made from PM 2.5 pollution. Learn how new carbon-based materials could disrupt age-old processes in industries like fashion, printing and packing — and make the world just a bit cleaner in the process.

  6. These inventions are useful for life

  7. Good idea
    Now every cheap “enterpreneur” will use it to tattoo people

      How can it be used to create tattoos? If it’s used for tattoos, then there’s no meaning in recycling that and saving people from air pollution since tattoos directly involve with the body tissues and reach inner parts of the body

    Great invention brother.. Very useful for our society

  11. Brilliant. Simply brilliant

  12. *Canon and InkJet have left the chat*

  13. This is really interesting! Something that is a ‘global killer’ has been taken and made into something that can be of use for so many people! Also, Mr. Sharma is a bit awkward, and I totally could relate… 😀

    Believe me,I see RECYCLING COMPANY as the biggest business in the near FUTURE,it’s just many are still not aware,like we would be literally using the same material again.

    Hi, did you guys figure out a more handy version of your pollution filter and collector for cars shown at 3:33? There is big market for a miniaturized version of this, as long as it doesn´t affect the engine power. Thats the crucial technology here.

    • I imagine that’s mostly a proof of concept, collecting particulate diesel fumes. The real-world application (to me) seems more likely to be power plants, stationary generators, etc. Though, a practical collector for cars would be great.

      +Joe Williams India is one of the most polluted countries in the world, if not the most. The minimal amount of energy lost due to air resistance may, be worthwhile in the city/factory area of India, but is ultimately useless in other areas where pollutants are controlled by governments, for example: America, China, UK.

      But, this is a great proof of concept that there are many unexplored areas for recycled/waste products.

  16. It’s always pleasant to see smart people solving real problems

    This is really innovative.
    But there are some concerns with this technology. The technology used here is similar to particulate filter which basically removes the 2.5 micrometer particles.
    The problem with such filters is that they generate back pressure,decrease efficiency of engine and end up creating more co2 emission.
    If they can tackle this problem it would be great.
    Check out the wiki page of air ink

    • he showed another prototype filter at 3:53 that was filtering a generator and he said it didn’t affect the performance, I’m not sure if that works on cars though coz he said the filter worked on static sources of pollution (I don’t know what that means but I assume its referring to stationary machines that give out pollution) so it pros doesn’t work on cars
      edit: oh yeah you said that the filters end up creating more co2 which is a definite flaw coz it just gets rid of one problem for another

  18. İn Istanbul they used to collect candle and oil smoke to produce ink until recently .. most famous one is the ink room in the suleymaniye mosque designed by Mimar Sinan
