Mumbai air polluted largely by coal-powered trade, higher tech and infrastructure wanted: CSE report

Some 1,400 medium- and small-scale enterprises in 4 industrial areas alone made up 70 p.c of polluting industries within the MMR.

Mumbai air polluted largely by coal-powered industry, better tech and infrastructure needed: CSE report

Whereas different sources of gas is utilized in all these sectors, coal continues to be the best used supply of vitality.

Mumbai’s air high quality is reportedly taking an enormous dip, and the quantity of coal being utilized in industrial sectors is essentially the most important contributor. Delhi-based non-profit organisation Centre for Science and Setting (CSE) just lately launched a report titled Enhanced Strategic Plan In the direction of Clear Air in Mumbai Metropolitan Area. The report presents an evaluation and estimate of air air pollution load from numerous industries throughout 4 areas within the Mumbai Metropolitan Area (MMR). These industrial areas are the Trans-Thane Creek (TTC), Taloja Industrial Space, Ambernath and Dombivali. A complete of 13 industrials areas exist in and round Mumbai – Ambernath, Badlapur, Chembur, Dombivali, Kalyan–Bhiwandi, Mira-Bhayandar, Marol, Patalganga, TTC, Taloja, Vasai-Virar and Wagle property.

The CSE research examined knowledge in regards to the gas consumption of those industries, with a concentrate on particulate matter (PM), sulphur dioxide (SO2) and nitrogen oxide (NOx) pollution, to get an estimate of air pollution load within the MMR. As per the European Setting Company, ‘air pollution loading’ is the quantity of stress positioned on an ecosystem by air pollution, bodily or chemical, launched into it by man-made or pure means.

Nivit Kumar Yadav, programme director, industrial air pollution unit, CSE advised Right down to Earth that the excessive air pollution ranges in Taloja is because of the usage of stable, soiled fuels like coal and agro-based fuels, and furnace oil.

“Mumbai is a coastal area and so, isn’t anticipated to have very excessive ranges of air pollution. However with speedy industrial and infrastructural improvement, air high quality of the area has began deteriorating. The town must get up and take corrective actions, to keep away from turning right into a air pollution pressure-cooker like Delhi,” Yadav added.

Gasoline, consumption patterns in MMR industrial areas

The report highlights the key industries working within the MMR: chemical (38 p.c), engineering (36 p.c), meals and meals processing (eight p.c), textile (seven p.c), development (three p.c), chilly storage (one p.c), pulp and paper (one p.c) and different miscellaneous industries (six p.c).

A complete of 1,400 medium- and small-scale operational models in simply the 4 industrial areas studied made up round 70 p.c of all of the industries working within the area, the report says. Chemical, engineering and meals processing (eight p.c) industries have been the key ones in Ambernath, Taloja and TTC. In Dombivali, chemical (38 p.c) and engineering (37 p.c) have been the dominant sectors. Whereas all sectors used different sources of gas too, coal remained essentially the most widely-used for vitality.

Simply 88 of the 1,389 industrial models of the 4 industries used PNG, as per the report. Greater than double that quantity – 196 models – used agro-based residues, and roughly 5 occasions that quantity – 419 models – relied on coal for vitality. The annual common coal consumption is about two million tonnes whereas liquid gas consumption is about 1.2 million tonnes and furnace oil is 0.2 million tonnes.

TTC was discovered to have the best coal consumption – accounting for virtually 60 p.c of all of the coal consumed within the studied space. TTC additionally contributed essentially the most to air pollution, at 44 p.c, adopted by Ambernath and Taloja, at roughly 24 and 26 p.c, respectively. Taloja’s consumption of PNG was the relative highest, and Ambernath was discovered to have the best liquid gas consumption.

Choking Dombivali

In 2019, Dombivali together with Chembur and Navi Mumbai have been recognized as critically polluted areas (CPAs) by Complete Setting Air pollution Index (CEPI) assessments. The evaluation discovered Dombivali, house to as many as 1,400 chemical corporations, was essentially the most polluted of the 4 industrials areas. An identical conclusion was arrived at by the CSE report, which discovered Dombivali and Kalyan essentially the most polluted industrial areas in Mumbai. Dombivali, being essentially the most populated space of these within the research, the poor air high quality was additionally more likely to have an effect on extra folks.

Amongst the probably causes for Dombivali’s excessive airborne PM, the report cites highway infrastructure, excessive ranges of uncontrolled air pollution from surrounding industries, and so on. Fixing these points is key to bringing the air air pollution scenario in MMR beneath management, the report factors out.


Together with the evaluation of the scenario, the CSE report additionally has a listing of actions that may be taken to make sure that Mumbai can repair its air air pollution downside. Listed here are a few of its options.

Whereas TTC and Taloja eat a big quantity of coal, there may be scope for industries in these areas to change to wash(er) fuels. Already, makes an attempt are being made by industries in Taloja to shift to PNG, and people in TTC to make use of agro-waste or briquettes. TTC consumes almost 70 p.c of the full agro-residue consumed in MMR. Controlling PM emissions in TTC and Taloja, the CSE evaluation mentioned, might help in lowering air air pollution in Mumbai and bettering the standard of air as properly.

One other measure the report recommends is to incentivize the swap to cleaner gas and inspiring polluting industries to make needed adjustments. The cleaner fuels additionally must be cheaper, so the industries discover the change equally if no more worthwhile, the report mentioned. If an space or trade isn’t capable of get PNG, CSE recommends that they not use high-sulphur gas oil. Subsidies must be given to medium- and small enterprises to assist them purchase air air pollution management gadgets whereas a correct mechanism is put into place to penalise medium- and large-enterprises for not doing the identical.

Additionally it is essential to observe Risky Natural Compounds (VOC) and different toxins within the ambient air the place chemical industries predominantly work, the report factors out. Conducting checks and shock visits to the industries to make sure compliance of the principles will guarantee ample follow-through, it added. A assertion from CSE highlights that higher infrastructure would additionally go a great distance along with the usage of know-how, like higher roads and drainage traces for public use that work extra effectively with much less vitality enter.
