Brickyard Pollution in Bangladesh

Faridpur, Dhaka.


Brickyards are the top air polluter in seven significant urban communities in the nation, especially during the dry season when most blocks are made, turning the air nature of these cities "seriously undesirable". Additionally to fault are development stir that kicks up dust, ineffectively kept up vehicles that discharge extreme destructive particles and harmful gases, and mechanical air contamination, as indicated by the Department of Environment (DoE).

Department of Environment (DoE) Research in Bangladesh

A five-year review by the office discovered Narayanganj has the most contaminated air, trailed by Dhaka. Third is Gazipur, which is trailed by Rajshahi, Chattogram, Khulna, and Barisal. The air in Sylhet city, in any case, is cleaner. The research was done somewhere in the range of 2013 and 2018 with assets from the World Bank.

Despite the fact that Dhaka came out second most exceedingly terrible in the nation, the World Health Organization (WHO) in 2018 said Dhaka was the world's third most noticeably awful city regarding air contamination, behind Delhi and Cairo.

Brickyards are the main CULPRIT

The examination discovered the air nature of these urban areas dives among November and April when brick ovens work and when there are many particles that are noticeable all around. The DoE installed gear at 11 spots in the eight urban areas to gather everyday information to set up the Air Quality Index (AQI).

The hardware gathered different information, including airborne particles, Sulfur Dioxide, Carbon Monoxide, and Nitrogen Oxides, which are all hurtful for wellbeing.

The AQI of 0-50 was sorted as acceptable,

  • 51-100 as moderate,

  • 101-150 preventative,

  • 151-200 unfortunate,

  • 201-300 exceptionally undesirable,

  • and 301-500 seriously unfortunate.

In 2018,

  • Narayanganj had 105 days with its AQI more than 301 (seriously undesirable).

  • Dhaka had such air on 83 days,

  • Gazipur 72 days,

  • Rajshahi 45 days,

  • Khulna 39 days,

  • Chattogram 13 days,

  • Barisal 9 days,

  • and Sylhet 8 days,

the overview report said.

On January 20 this year,

  • Narayanganj scored 475,

  • Gazipur 400, Dhaka 382,

  • Chittagong 361,

  • Rajshahi 356,

  • and Barisal 335.

In the 2017-18 financial year, a large portion of the air contamination in Dhaka was brought about by brickyards while development work contributed around 25 percent and vehicle discharge 10-12 percent. So the brickyards are the main culprit of air pollution.

There are 7,707 block ovens in the nation, remembering

  • 366 for Barisal division,

  • 1,529 in Chattogram,

  • 256 in Sylhet, 2,295 in Dhaka,

  • 873 in Khulna

  • and 1,176 in the Rajshahi division,

as per the most recent DoE information.

The advanced innovation

Making blocks utilizing these following strategies requires less coal or wood, henceforth less contamination. For instance, a regular block oven requires 20 tons of coal to make 1,00,000 blocks, far more than 13-14 tons expected to make an equivalent number of blocks utilizing present-day innovation.

The administration is currently advancing present day innovation for brickyards like Hybrid Hoffman and Tunnel innovation. Half and half Hoffman Kiln (HHK) innovation was created and is broadly utilized in China. The HHK consolidates the utilization of green blocks delivered by blending powdered fuel in with mud; and usage of waste warmth by moving the warmth to a contiguous passage.

Health Issues

As indicated by a World Health Organization (WHO) report delivered in May in 2019, around 7 million individuals kick the bucket all-inclusive consistently from presentation to fine particles in contaminated air that enter profound into the lungs and cardiovascular framework. It causes ailments including stroke, coronary illness, lung malignancy, ceaseless obstructive aspiratory ailments, and respiratory diseases, including pneumonia.

Open-air contamination alone caused some 4.2 million passings in 2016 while air contamination inside, from cooking with dirtying energizes and advances, caused an expected 3.8 million passings during a similar period.

In excess of 90 percent of the passings were in low-and center salary nations, for the most part in Asia and Africa, said the WHO report.

"The WHO perceived that air contamination is a basic hazard factor for non-transmittable maladies, causing an expected one-quarter (24 percent) of every single grown-up death from coronary illness, 25 percent from stroke, 43 percent from constant obstructive pneumonic sicknesses, and 29 percent from lung malignant growth," it read.


As we have seen the reports, brickyard pollution has become an alarming issue in Bangladesh. And in the countries where you can find the cole brickyard. Air is at high risk. And already being damaged.

Trees are being cut down; to give the fuel to the brickyards. If there are any brickyards near a fertile land, that would be damaged very soon. It has gone to an extreme level in Bangladesh.

If we don’t start Greenism at this time, It will be very late. And the next generation will suffer the consequences.
