The factory makes thousands of hand-made bricks everyday, but the technology is over 150 years old. In that time, it's received little upgrading and continues to use high-sulphur coal and wood.
It is one of the country's biggest sources of greenhouse gas. In fact, according to the United Nations Development Programme, the brick kilns emit between 3.3 to 6 million metric tonnes of carbon dioxide annually.
It's estimated as much as 30 percent of the pollution comes from the brick kilns. The thick smoke is a big factor in respiratory illnesses such as asthma.
People living around the industry, not only inhale the fumes, but the wind whips up dust blanketing everything with a thick sand layer. Children are particularly susceptible, many suffering from coughs, colds, fevers and breathing problems.
Even worse, rich alluvial topsoil is used to mould the bricks. Once the topsoil is used, it can no longer be utilized for farming. Fruits and vegetables are also unable to grow because of the smoke.
The effects of air pollution are particularly bad for children, mainly because they don't go indoors or stop playing when air quality decreases.
It's an extremely devastating situation, with at least 1,999 brick fields operating without the proper government clearance -- most of them near Dhaka.
The government will enforce a plan starting at the end of the year. They'll stop renewing operation certificates for traditional brick-makers. The hope is that workers will adopt the proper environmentally friendly practices.
