Increasing heat creates hardship for kiln workers in Chennai ...
kilns are estimated to consume roughly 25 million tons of coal per year, making them among the highest industrial consumers of coal in India [CATF, 2012], [UNEP, 2011]. Switching to sundried mud/clay bricks would change the way bricks are made, making the process itself less hazardous for workers, and less polluting for the environment.
