Supertech's Emerald Court twin towers were demolished. It generated 80,000 tonnes of debris which will be recycled for further use. Building material will be made from the 80,000 tonnes of debris of Emerald Court likely solving a concrete problem for the environment.
Two companies are working to dispose of the concrete, bricks, tiles, and steel. Edifice Engineering will pick up 350 tonnes of iron and steel, and Hyderabad-based waste management company Re- sustainability and Recycling Pvt Ltd will handle the rest of the debris.
“First of all, steel and iron will be separated by taking the debris to the plant. After that, we will break the steel and iron into 250 mm pieces and give them to the Noida Authority. There is also a system to recycle and reroll the steel," said Utkarsh Mehta, Partner at Edifice.
Mehta said his team works all over India to sell recycled steel from 20 branches. The company has rolling mills and traders who sell their products. Once the iron is removed, the concrete and other rubble will be used to make brickbat, bricks, and tiles.
About 28,000 tonnes of tiles lie in Edifice’s rubble. Re Sustainability will take up the work to dispose of them. The company has a concrete and demolition plant in Noida for tiles. The 5-acre plant has an agreement with the Noida Authority till 2034.
Mukesh Dhiman, project head at the plant said that about 30,000 tonnes of debris from Emerald will come to the plant. Some 50,000 tonnes of debris will be buried, and the rest will come to the plant later. The plant, which has a processing capacity of 850 tonnes per day, manufactures 2,500 tiles daily, and it can scale up to 5,000 tiles. The plant receives about 350 tonnes of debris daily from Noida and recycles 95 percent.
During processing, 10, 20, and 40 millimeters of manufacturing sand and core sand are generated. Of these, tiles are made from 10 and 20 millimeters of sand. The company's tiles, branded as 'Re Sustainability', are 30 percent cheaper. They are roughly priced at Rs 18 per tile. If the government agrees to buy tiles, they will be sold in bulk at Rs 12 per tile.
About 40 millimeters of sand is used for making roads, sidewalks, and plain cement concrete (PCC). Dhiman said such sand is used for low-weight construction materials, such as flooring, plaster, and bricks. It cannot be used for laying roofs. This sand and concrete prepared during processing will also reach the market at a price of Rs 200 per tonne.
