Posted On: 07 AUG 2023 4:04PM by PIB Delhi

A pilot study was awarded wherein 30 buses were fitted with Pariyayantra Filtration units on bus roof top for dust collection from the environment in Delhi-NCR.

Several projects were undertaken to incorporate new technologies to address air pollution. Details are enclosed at Annexure-I.


Details of studies undertaken for incorporation of new technologies to address air pollution


  1. Under pilot study of WAYU, 54 Air Purification Units were installed at traffic intersection in Delhi.
  2. Pilot study on ‘Control of Dust emissions using Dust Suppressant’
  3. Pilot study on ‘Ionisation technology for reduction in ambient air pollution’
  4. 2 Smog towers as medium/large-scale air purifiers to reduce particulate air pollution were installed.
  5. Pilot project on ‘Emission measurement for in-use diesel generator sets (DG sets) and evaluating the potential of retrofitting exhaust after treatment solutions for emissions reductions.
  6. Pilot Project on ‘Retrofitting emission control devices in identified classes of in-use vehicles and recommendations for emission reduction from old/in-use vehicles (BS III)’
  7. R&D project of DST for development of indigenous photonic system for real time remote monitoring of air quality parameters.
  8. DST National Mission on Interdisciplinary Cyber Physical Systems (NM-ICPS), Technology Innovation Hub on Autonomous Navigation Foundation on ‘development of Electric Vehicle (EV) based autonomous vehicles’. Autonomous technology of EVs has potential to reduce greenhouse gas emissions by optimizing driving patterns and reducing traffic congestion.

This information was given by Union Minister of State for Environment, Forest and Climate Change Shri Ashwini Kumar Choubey in a written reply in the Lok Sabha today.
