Noida: On August 28, 2022, the twin tower building in Noida's Sector-93A Supertech Emerald Court was demolished, resulting in 80 thousand of tonnes of debris. The deadline for disposing of the debris was set for November 30, 2022, but due to various obstacles, the work could not be completed on time. The Noida Authority had given the demolition company Edifice a deadline to dispose of the debris by November 30, 2022. However, due to the introduction of the Graded Response Action Plan (GRAP) on November 9, 2022, the work was halted. The debris removal work resumed in March 2023, and as of now, 70% or 56,000 metric tonnes of debris have been disposed of.
The remaining 24,000 metric tonnes of debris will be used to fill the basement, and a 310-meter pathway will be constructed. The RWA had raised concerns about the vibrations caused by the raft breaking during the debris removal work. The Noida Authority had asked the Central Building Research Institute (CBRI) to examine the vibrations and submit a report. The report was satisfactory, and the work resumed.

The RWA again raised concerns about noise pollution caused by the debris removal work in December and January. The pollution control department conducted a survey and found that the noise level was 10 decibels above the standard limit. The authority directed Supertech and Edifice Engineering to carry out the work between 6 am and 3 am, and they can work until 10 pm if they take appropriate measures to reduce noise levels. The RWA agreed to this.
Under the agreement reached between Edifice and Supertech, the cost of demolishing the tower was 17 crore, of which 4 crore was paid by Supertech. The rest of the money would have been collected by the company through the sale of the bars. The company management stated that Rs 13 crore would be recovered by selling rebar and steel coming out of the debris. In which rebar worth nine crore rupees has been removed. While 3 crore bars are in this basement, which can only be extracted after digging the raft.
The debris of the Twin Towers has been disposed of at the C&D Waste Plant in Sector-80, Noida. Tiles were manufactured from this debris. Supertech paid a processing fee of Rs 156 per meter cube for the disposal of debris in the plant.
