Recycling environmental air pollution and convert it to paints/pigments and printing ink.
We introduce project KAALINK with the vision of converting/recycling air pollution into industrial grade paint/inks. Soot (Black Carbon) is a mass of impure carbon particles resulting from the incomplete combustion of hydrocarbons i.e. air pollution. It is produced by vehicles and industries alike. Breathing-in soot is linked to a wide range of serious health effects, including premature death, heart attacks, and strokes, bronchitis and aggravated asthma among children. Project Kaalink solves that.
We demonstrate this by building a contraption that supplies the ink to HP C6602 inkjet cartridge interfaced with Arduino turning it into ~ 100dpi print platform.
