The Supertech twin towers in Noida were pulled down within 9 seconds at 2:30 pm on Sunday.
For the demolition, about 3,700 kg of explosives, which were brought from Haryana's Palwal was used. It was a mix of dynamite, emulsions and plastic explosives.
According to the estimates prepared by project officials, the demolition would leave behind approximately 35,000 cubic metres of debris to be cleared and clouds of dust to dissipate.
Noida Authority’s General Manager (Planning) Ishtiaq Ahmed said 21,000 cubic metres of the debris would be moved out and dumped at an isolated land.
At least 4,000 tonnes of iron and steel is expected to emerge from the debris, which Edifice will use to partly recover the demolition cost.
Cleaning is underway at twin tower demolition site. 22 anti-smog guns are being used to ensure clean dust environment for the residents.
