This Indian startup is capturing the dirty pollutant known as particulate matter from diesel engines and turning it into ink. Dell has already begun buying Chakr’s ink to print text on boxes, a small step towards reducing the millions of annual deaths that result from particulate matter pollution. Problem Air pollution causes 4.2 million premature deaths every year. 9 out of 10 breathe air containing high levels of pollutants. Solution Emission control technology to reduce emissions by over 90%. Captured pollution is converted into usable products like inks and paints. Impact Clean air for everyone to breathe while ensuring that it does not become airborne again. We have developed world’s first retro-fit emission control device for diesel generators. Our technology can capture ~90% of particulate matter emissions from the exhaust of diesel generators without causing any adverse impact on the engine.
