AIR-INK is currently available as 2mm, 15mm, 30mm and 50mm markers, and as 150ml of screen printing ink.

What is AIR-INK made of?

AIR-INK is made out of air pollution particulate matter––namely the unburned carbon soot you see coming out of the exhaust pipe of cars, chimneys, generators, and more.


The process


AIR-INK is created through a three-step process.


Step 1. While cheaper carbon black inks are manufactured through the deliberate burning of fossil fuels, we use our proprietary device––what we call KAALINK––to capture soot that is already being emitted from vehicles. KAALINK is retrofitted to the exhaust pipe of vehicles/generators to capture the outgoing pollutants. 


It takes just 45 minutes worth of vehicular emissions captured by Kaalink to produce 1 fluid ounce of ink––enough to fill one of the pens being offered through this Kickstarter campaign.

Step 2. The soot they collect undergoes various proprietary processes to remove heavy metals and carcinogens. The end product is a purified carbon rich pigment.

They purify the carbon pigment by cutting out the heavy metals, dust particles, and all other harmful materials.


Step 3. The carbon is then used to make different types of inks and paints.

They use standard industrial processes to create ink that is as safe as any on the market.


The end result


They have created several grades of AIR-INK with different applications: 2mm round tip and 15mm, 30mm and 50mm chisel tip markers, and screen printing ink.

How can I use AIR-INK? 


AIR-INK is currently available as 2mm, 15mm, 30mm and 50mm markers, and a 150ml screen printing ink set. If this campaign is a success, we will be able to work towards releasing oil based paints, fabric paints, outdoor paints, and more.
