Executive Summary : | Incomplete combustion associated with domestic heating activities using solid fuels, especially during household cooking and cultural burning practices, are known for emissions of hazardous gaseous pollutants such as carbon monoxide (CO), oxides of nitrogen (NOx), sulfur dioxide (SO₂) and non-methane volatile organic compounds (NMVOCs) that adversely affecting respiratory and dermal systems of people involved with such practices. In Chhattisgarh, ~63% households rely on unprocessed solid fuels (coal balls, dung cake, agriculture residues and fuel wood) for cooking. Earlier studies conducted in the state (SERB project EMR/2015/000928) on solid fuel burning emissions exhibit two to four times higher emissions for PM2.5, carbonaceous material, ions and VOCs compared to those reported for laboratory test-chamber based studies. This project intends to estimate emissions and develop removal methods for hazardous gaseous pollutants released from domestic solid fuel combustion. The scientific research questions to be addressed are: 1) how does incomplete combustion affect combustion efficiency and gaseous emission rates for domestic solid fuels used for cooking and cultural practices in the real-world situations?; 2) how can the absorption/adsorption properties of carbon-fiber based engineered nanocomposites using metal oxides and/or metal organic frameworks (MoF) be improved to capture more multi-species pollutants?; 3) How effective are nanocomposites in removing hazardous pollutants from emissions at the source?; and 4) to what extent are nanocomposites adaptable to low-cost devices for pollution emission controls? Recent studies address reduction of hazardous components in emitted smoke from solid fuel burning mainly focused on improving combustion properties by redesigning cookstoves. This project would take the next logical step to further remove these pollutants from the smoke plume using physical chemical adsorption/absorption properties of engineered carbon fiber based nano composites. Emissions estimates for a variety of pollutants, including CO, NOx, SO2, and TVOCs, will be developed for different types of solid fuel/s burning practices in household cooking and cultural activity purposes, followed by development of functionalized carbon fiber based nano composites for pollutant removal. The PI has 27 years of continuous experience dealing with air pollution monitoring at sources and in classified atmospheric environments. Similarly, the Co-PI has 10 years of experience in synthesizing engineered carbon fiber based nano composites, potentially known for higher absorption/adsorption capabilities. |
