Pune's brick kilns, coal-fired power plants, and waste burning contribute to poor air quality
Pune, India, has been struggling with poor air quality, with the city's air quality index (AQI) fluctuating between moderate and poor in recent times. The city's brick kilns, coal-fired power plants, and waste burning practices significantly contribute to this issue.
There are approximately 150 brick kilns between Pune and Pimpri-Chinchwad, mostly fuelled by coal and agri-waste. Brick kilns are recognised as one of the largest stationary sources of black carbon, contributing significantly to air pollution. The burning of coal and other fuels releases harmful pollutants such as SO2 and particulate matter (PM), including PM2.5, which has been associated with respiratory and cardiovascular health issues. The small particles produced by incomplete combustion are absorbed deep into the lungs, leading to serious health problems for workers and nearby communities.
The coal-fired power plants located outside the urban airshed also contribute significantly to Pune's air pollution. These plants release various pollutants, and stricter environmental standards need to be enforced to mitigate their impact. Additionally, open waste burning is dispersed across the city, and the lack of efficient sorting and disposal systems exacerbates the problem. The city's growing waste generation and limited capacity to manage it effectively contribute to the air quality issues.
Furthermore, Pune's well-established manufacturing, glass, sugar, and metal forging industries, along with the recent development of information technology and auto industries, have increased industrial emissions. Fugitive dust emissions from quarrying, diesel power generation, vehicle exhaust from heavy-duty trucks, and manufacturing processes all contribute to the city's poor air quality.
To improve Pune's air quality, a multi-faceted approach is necessary. Upgrading technology in brick kilns to improve energy efficiency, enforcing stricter environmental standards for coal-fired power plants, implementing better waste management practices, and promoting sustainable transportation options are all crucial steps that can be taken to reduce air pollution in Pune.
