However, they are reusable – should a building be demolished, the bricks can be cleaned and reused as new building material or paving.

Why are brick kilns bad?

The brick kilns emit toxic fumes containing suspended particulate matters rich in carbon particles and high concentration of carbon monoxides and oxides of sulphur (SOx) that are harmful to eye, lungs and throat. These air pollutants stunt the mental and physical growth of children.

How does brick kiln cause air pollution?

Air pollution in brick kiln is produced both through the stack emission as well as the fugitive emissions. Use of thermally low efficient kilns, outdated technology such as Bull’s Trench kilns and inefficient firing technologies contributes to particulate and gaseous emissions.

Which gas is produced by brick kilns?

According to the report of UPPCB, the sulphur dioxide gas released from these kilns is leads to itching in the eyes, carbon monoxide and carbon dioxide cause increased temperature and the presence of oxides of nitrogen in the air leads to lung and skin infections.

What kind of pollution is caused by brick making?
