Chakr Innovation: Printing with Pollution

New Delhi | India

Chakr Innovation is a two year old start-up based out of Delhi which converts soot into paint.

Chakr is trying to bring down Delhi's air pollution level, largely caused by diesel generator emissions. Such emissions lead to PM density as high as 300 micrograms per cubic metre while WHO's safety limit is 23 micrograms per cubic metre.

Chakr Shield, a retrofit device by Chakr Innovation fits in the exhaust pipe of a diesel generator and captures 70-90 per cent of the particulate matter, ranging from PM 1 and PM 2.5 to PM 10. The captured material is passed through an air cooler exchanger pipe and stored in a solvent. The soot produced is converted to ink in Chakr's processing unit, which can be used for printer cartridges and paint.
