Good news for Delhi residents! A device that has the power to turn pollutants into ink. Yes, you read that right. Delhi people can heave a sigh of relief and expect the pollution levels to come down to normal levels soon. A startup known as the Chakr Innovation has recently tied up with the Delhi government and is testing the device that can convert air pollution from diesel generator sets to ink, according to Indian Express. The device which is being called as ‘Chakr Shield’ has a ‘chakr’ or circle that denotes the closing loop for black carbon. The device has the power to capture 90% of particulate matter emissions.
The device is currently being tested at the Indian Institute of Technology (IIT) Delhi and also at some factories in Gurgaon, Noida and Ghaziabad. Retrofitting the device to diesel engines is key, as they are one of the major sources of air pollution. Dhupar said that the device traps not just PM 2.5 particles, but particles as small as 0.3 micrometres in diametre, the report stated.
Chief technology officer, Amit Dhupar while talking of the device which is currently being tested said, “It uses a solion-based method and is one of a kind. It doesn’t cause an adverse impact on the environment. The captured pollutant — essentially black carbon — is processed and converted into ink and paint.” The Chakr Innovation is a Delhi based start up that was founded back in 2015 by three tech graduates — Dhupar, Kushagra Srivastava (22) and Prateek Sachan (22). They launched theit pilot project in 2016 and won the University of Chicago’s ‘Urban Labs Innovation Challenge’ in the same year. The University of Chicago’s ‘Urban Labs Innovation Challenge’ is a partnership between the university and the Delhi government and it seeks to crowd-source local ideas to cut pollution in the capital.
Dhupar added, “This year, we are going to test the system at 25 different locations in Delhi. These tests will take place alongside 25 other sites where the device will not be present. Throughout the year, pollution levels in these locations will be compared. Our own monitors will check the air pollution levels continuously, while a third party will monitor the air in the area twice a month,” as quoted by Indian Express. The report added that the device’s performance will be the basis on which the Delhi government will decide on whether the technology deserves large-scale implementation.
