– Environment Minister Dr Harsh Vardhan flags off 5 buses from Paryavaran Bhawan
– As a pilot, CPCB has given a work order of 30 buses to Manav Rachna under EPC funds

CPCB will try a new innovation this winter to improve the deteriorating air quality of Delhi. A pilot project to demonstrate the effectiveness of outdoor air pollution mitigation has been awarded to Manav Rachna Innovation and Incubation Centre (MRIIC) under EPC funds. The project Pariyayantra will be installed on the roof top of 30 buses in Delhi.
Pariyayantra was formally flagged off by Dr. Harsh Vardhan, Hon’ble Minister for Science & Technology, Environment, Forest and Climate Change and Earth Sciences from the Paryavaran Bhawan in New Delhi today. He was accompanied by senior officials from the Central Pollution Control Board (CPCB) and the Environment Ministry.
A team of researchers from Faridabad-based Manav Rachna Innovation and Incubation Centre (MRIIC) comprising Dr. B S Gill, Amit Kumar and Prachie Sharma have devised this revolutionary product “Pariyayantra” -an ‘Air Pollution Mitigation’ product that cleans atmospheric air through filters fitted on vehicles. Pariyayantra does not require any power to operate and is equivalent to the filtration provided by 6 room air filters.
These are air filter units that can be mounted on the roof of any vehicle — buses, cars, auto-rickshaws and even two-wheelers. As the vehicle moves, air passes through the holes in front of the device. The filters fitted inside the unit trap the pollutants. What comes out is clean air. At least 30 such devices will be fitted on the roofs of buses in Delhi this winter on a pilot basis.
“During experiments, we found the filters can trap up to 98% of the particulate matter and this led to the genesis of the product Pariyayantra,” says BS Gill, the professor who led the research team.
