Après le séchage des briques d'argile brute, elles sont empilées à l'intérieur d'un four de briques à cheminée fixe le long de la rivière hazy Turag à Asulia au Bangladesh. La zone est remplie de fours de briques à cheminée fixe, qui viennent de transformer leur production en grande vitesse. Pendant la plus grande partie de l'année, les fours en briques sont inondés car ils sont situés sur les lits de la rivière. Lorsque l'eau recule pendant la saison sèche, les fours reviennent à la vie alors que des centaines d'ouvriers empilent des briques fraîchement pressées en silt dans d'énormes fours à bois et à charbon. En utilisant une technique simple qui remonte des centaines d'années, la cheminée fixe bric

After the raw clay bricks are dried, they are stacked up inside a fixed chimney brick kiln along the hazy Turag river in Ashulia in Bangladesh. The area is filled with fixed chimney brick kilns, which have just switched their production into high gear. For most of the year, the brick kilns are flooded as they are located on the river beds. When the water recedes during the dry season, the kilns come back to life as hundreds of workers stack freshly pressed bricks made from silt into huge wood and coal fired ovens. Using a simple technique going back hundreds of years, the fixed chimney brick kilns provide a steady supply of cheap bricks to a rapidly growing country and importantly employ over one million seasonal workers. They are also a major source of headache. Literally. More than 23 billion bricks are produced annually in some 7000 coal and wood fired kilns. Although true and tested, the fixed chimney kilns are also very inefficient. The resulting toxic fumes literally covers the Bay of Bengal in a thick, unhealthy smog. Known as PM 2.5 (particular matter smaller than 2.5 microns) the small dust particles in the fumes are small enough to be absorbed by humans and animals through inhaling and are linked to premature death and lung diseases as well as respiratory chronic illnesses such as asthma and bronchitis. At the time of this picture, the PM 2.5 values in the area was 7 times higher than what WHO considers healthy. Flights in and out of Dhaka were suspended due to lack of visibility. Then there is the climate: While the high density of dust can contribute to a regional cooling, the sum of the impact is devastating to the planet. Direct carbon emissions from the kilns alone stands at more than 9 million tons per year. Add to that the deforestation and long-haul sourcing of the wood and coal for the kilns, and the numbers get much worse.
