Technological solutions being devised by IIT Delhi for reducing & tackling air pollution in the country

IIT Delhi has established a Centre of Excellence for Research on Clean Air (CERCA) in February, 2018 to help researchers and scholars promote scientific research and devise effective solutions to the problem of air pollution through a collaborative, constructive and solution oriented approach.

The following projects have been undertaken by the CERCA:-

a. Studying the best practices on Air Pollution Reduction Programs around the World especially Japan and China with a specific focus on policy formulation, governance and Implementation Issues.

b. A study for prediction of PM2.5 levels at different locations in Delhi-NCR using machine learning and impacts of various interventions to curb air-pollution using advanced modelling techniques.

c. Identification of upwind districts in Punjab and Haryana from where crop burning contributes most to air pollution in Oct-Nov in Delhi-NCR by studying the extent of burning and wind patterns using satellite data. The final report including findings and policy recommendations have already been sent to government of Punjab, NITI Aayog and MoEF&CC.

d. A Study is being done for identification of brick kiln clusters which contribute most to pollution in Delhi-NCR and feedback to policy makers to judge the effectiveness of the mitigation measures implemented to curb pollution due to these sources.

e. A study on Identification of coal fired thermal power plants within a radius of 100 Kms of Delhi NCR which because of their emission levels and wind patterns cause maximum air pollution in Delhi-NCR and feedback to policy makers to judge the effectiveness of the mitigation measures implemented to curb pollution due to these sources.

f. A study is being planned to deploy air pollution sensors on DIMTS buses in Delhi to measure the extent of air pollution in different areas and routes in the city and develop forecasting models based on the study.

g. A base line study is being carried out to measure Indoor air pollution at various schools, residential complexes, metros, malls, restaurants in city of Delhi.

g. A base line study is being carried out to measure Indoor air pollution at various schools, residential complexes, metros, malls, restaurants in city of Delhi.

h. It is proposed to develop an air quality performance index for cities which would be integrated with NCAP.

i. A study is being planned to carry out the carbon foot print of IIT Delhi and making it carbon neutral with support from NITI Aayog. The model once approved and accepted by NITI Aayog would be extended to other cities as well.

j. IIT Delhi has developed a process to convert agro-waste such as stubble into pulp which can be used to make bioethanol, paper, and tableware and also helps the farmers generate profits from their waste instead of burning it off and can help in reducing pollution caused by burning of crop residues. IIT Delhi is working on collaborating with industry on developing an In Situ Rapid Waste Decomposition Technology.

k. IIT-Delhi, is working on creating low cost air pollution monitoring network using low-cost air pollution sensing devices to predict the real time concentration of pollutants such as PM (1.0, 2.5, 10), C02, CO, Ozone, SOx and NOx on a single compact platform at any given point in a mapped area.

i. CERCA is also conducting various workshops on sensitizing stakeholders on various aspects of air pollution. Some of the workshops conducted include “Workshop on stubble burning”, “Workshop on a path to clean air”, Conference on “Reducing fine particulate matter concentrations”, Air quality round tables etc.

Startups working to combat air pollution:

  1. FITT Incubated startup: Nanoclean Global Pvt. Ltd. - Nano clean has developed preventive measures for combating polluted air. The team has developed a Naso-filter that can stick to the nose orifice and does not cover the face as a regular mask, thus allowing prolonged use while communicating with others. The startup has also developed products like AC mounted filters to convert ACs into air purifiers, window screens to prevent entry of particulate matter and also industry grade masks.

  2. FITT Incubated startup: Kriya Labs Pvt. Ltd - Kriya labs provides Packaging Solutions using only eco-friendly value-added materials from waste natural materials/fibres. The startup has developed an efficient process to convert paddy stubble into pulp that can be converted to value added products like food packaging, tableware and textiles. The initiative on one hand helps reducing air pollution caused by rice stubble burning, while simultaneously providing alternatives to plastics for disposable food packages.

  3. FITT Incubated startup: Aerogram Pvt. Ltd - The Ezio air pollution monitor is a small handheld device that can monitor the level of pollution in our local environment like inside a room, car, or outdoors. The data from these devices can also help to create a detailed map for entire cities and figure out the levels of pollutions in different areas. This can help in planning our activities and preventing exposure to high levels of particulate matter.

  4. IITD Alum promoted startup: Chakr Innovations’ Chakr Shield is the first retro fit device that traps the particulate matter in the diesel generator exhausts and converts it to ink that can be used for drawings. The patented technology can trap 90% of particulate matter in the exhaust, thus reducing the PM pollution caused by diesel gensets.

  5. ShudhVayu Innovations is a startup which has been offered incubation at FITT. It works on a unique concept which claims to remove PM10 in bulk by installing the design registered air purification device on a multitude of vehicles.
