Turning Air pollution into ink by Chakr Innovation
Sep 9, 2017
Great innovation and love recapture/repurposing of "waste" materials!
You have developed a well-rounded proposal that draws on appropriate expertise, but there is some confusion between air pollution and greenhouse gases. Whereas air pollutants cause respiratory problems, greenhouse gases exacerbate climate change. Interestingly, historic solutions to air pollutants (NOx, SOx, PM, etc.) have had the counter effect of increasing GHGs--solutions can be at cross purposes, unfortunately, which leads me to the question: Does your process for capturing air pollutants inadvertently increase the GHG potential of the exhaust system?
I am also curious about the health standards of diesel-based ink. People are physically close to ink when they are using it (or even reading it or throwing paper printed with it into fires or compost piles, etc.), what are the health implications of using ink made up of air pollutants captured from diesel engines?
Finally, an interesting irony in capturing particulate matter is that the smaller the PM (e.g. PM25) captured, the smaller the PM still out in the environment. So, we first captured PM10 and stopped seeing hideous black exhaust, but still suffered respiratory problems. Then we refined our filters and captured PM25, but realized that everything smaller was now passing through without detection--we think there is less pollution, meanwhile the most incipient of particles continue to enter people's lungs. Have you looked into such implications?

Great work Charkr,
But have you thought of ways of collecting the ink from the different generation point. Because I was just thinking that how many people will consider the option of going to sell the ink other than just emptying it down the drain. Does this device incorporate a mechanism that keeps the ink inside a form of casement until it is ready to be use? Or would you rather incorporate a buy back process of the ink for those that purchase your device?
Wish you best of luck at the semis.

Congratulations for making it to the finalist selection stage.
I just want to know the extent to which you consider the sustainability of your product, because the future of fossil fuels for energy generation is getting dim as we are moving towards renewables. if there are no more emissions from diesel generators (because we probably didn't need them again), what other use can your product be put to?
All the best.

Thank you for liking our project.You are right that as we are moving towards renewables, our dependability on fossil fuels will diminish and the usage of diesel generators will also reduce. But in many developing countries such as India, Bangladesh etc., there is still lack of constant grid energy or feasibility of renewable energy in densely populated areas. So there is huge dependence on DGs for power backup for 5-10 years.
Also in parallel, we are continuously working on new technologies for other sources of Air pollution such as boilers and chimneys which are used in industries.
