‘Chakr Shield’, captures and converts soot emitted by diesel generators into ink pigments, which in turn is used for painting, textile printing, and paper printing. The shield, when attached to the exhaust system of diesel generators, captures around 75 to 90 percent of particulate matter, a kind of air pollutant, which is also one of the main constituents of soot. “Along with controlling emission at the source, our technology also ensures that the collected particulate matter is not disposed-off or burnt but is used as a raw material for inks and paints,” says Kushagra Srivastava, CEO and co-founder.
