BHUBANESWAR: The Odisha State Pollution Control Board has directed the Bhubaneswar Development Authority (BDA) to promote use of fly-ash bricks in construction work.
"BDA officials were told to impress upon builders, coming for plan approval, to use these bricks," said OSPCB senior scientist D K Behera.
He said the board would facilitate procurement of fly ash from thermal power plants, located within 100-km radius of construction area. "Fly-ash bricks are stronger than the clay ones. These bricks were earlier used in areas close to the plants. To dispose of fly ash dumped in ponds, which is a threat to the environment, the board mooted the idea," Behera added.
BDA vice-chairman Krishan Kumar said use of fly-ash bricks would soon be made mandatory. "It will be included as a clause in the building plan approval. We will finalize the modalities in the next meeting," he added.
According to OSPCB report, around 110 million tonne of fly ash are stacked in the ponds of 40 major thermal power plants. Only 54% of the total ash generated from industries is being utilized. "Fly ash contains at least 22 heavy metals of which 18 are cancerous and can lead to lungs, bone and other diseases. Its disposal and utilization should be a top priority," said a senior pollution board officer.
