Air Pollution has been one of the most conspicuous of all the problems we face today. If not captured it causes health problems, global warming, haze- billions of dollars worth of losses to governments.

“Pollution is nothing but the resources we are not harvesting. We allow them to disperse because we've been ignorant of their value. - Buckminster Fuller “

Both. Fossil fuel based air pollution is rich in carbonaceous particulate matter. Hence, the idea is to confine and bind that captured pollution into high grade inks that everyone can use and express themselves with through art or writing.

KAALINK is a post tailpipe retrofit. It’s a mechatronic system which consists of filters, sensors, and a capture unit. Our capture technique is a fusion of electrostatic filtration, depth filtration, wall flow filtration, etc. The filtration technologies are pipelined with each other to achieve the desired filtration granularity.

The system is under rigorous testing process right now, and is installed adhoc on diesel generators and automobiles, that produce fossil fuel emissions.

The captured pollution contains toxic impurities like re-entrant dust, heavy metals, oils, VOCs etc. This is purified by proprietary chemical processes beginning with gravity based separation for high-mass particles, to comminution and catalysed activation. Finally the recovered soot is taken through a grinding process to bring to a consistent particle size, as good as an ink pigment.

The process of making Air Ink not only eliminates soot from polluting the air, but it also doesn’t burn extra fossil fuels that making regular ink does.

The generated waste during the process are mainly of type A4, B1 and B2 according to the MoEFCC. We use the services of a leading waste management company to sort and recycle them accordingly.

The particulate matter derives its carcinogenic properties from its ability float in air and thus being able to enter into our respiratory system and settling in lungs. By binding the captured pollution into inks, we are able to take away its ability to float in air.

No, AIR-INK is as safe as any other ink available in the market. However, Graviky is yet
to test and declare it safe for children below 6 years of age. And, our inks are not edible, no! :)

We are a PCT patent-pending technology. Papers with details on our testing and results will be submitted to SAE, and other journals for publishing.
