In Pollution-Choked Delhi, a Team of Engineers Is Turning Diesel Soot Into Ink and Paints

It all started one day when Arpit Dhupar, an IIT Delhi alumnus, and his friends were at a roadside stall, getting their fill of sugarcane juice. The cane crusher was running on a diesel generator but its emission was not visible because the vendor had attached an exhaust pipe to divert the carbon emissions to a wall.

For Arpit, it was a moment of epiphany. He noticed that the emitted soot had painted the wall black and wondered if it could be something bigger. “If it can colour the wall black, it can surely be utilised as paint,” he thought.
