Delhi is digging hard to don a smart green look for the Commonwealth Games in October. In the process, it’s producing 4,500 metric tonnes of construction and demolition waste every day, up from the 2,500 metric tonnes till a few months ago.
The Municipal Corporation of Delhi (MCD), meanwhile, has hit upon an ingenious idea to deal with the waste.
The civic agency has tied up with private firm IL&FS Waste Management & Urban Services Limited to collect the waste and recycle it to produce tiles, kerbstones and pavement blocks.
The company has already received orders from Delhi Development Authority and Delhi Metro Rail Corporation to start the recycling and production.
Breather for landfill sites
“The sanitary landfill sites where such waste is dumped are already overflowing as result of which construction waste is left on the streets,” said MCD director, press and information, Deep Mathur.
“We have started this pilot project wherein the construction waste is collected by the private firm from various collection points. The waste is then transported to a plant in northwest Delhi’s Burari where it is processed.”
The waste is collected from 42 sites located in three zones under the civic agency — Sadar Paharganj, City zone and Karol Bagh zone.
“Either bins are placed at collection points or waste is loaded in tipper trucks,” a senior MCD official said. If the project turns successful, the model will be replicated across the city.
“Most landfill sites are overflowing and through recycling the waste, we will be able to increase their life,” said Mahesh Babu, managing director, IL & FS Waste Management & Urban Services Limited. “There was no solution of treating such waste which is why we came up with this idea.”
The plant in Burari has a ‘mobile crushing facility’ to handle approximately 500 tonnes of waste every day.
“The Supreme Court has put restrictions on the mining of such material. So, we will have to rely on recycled building material in future. It will also save us from spending money on transport of debris to the sanitary landfill sites,” the MCD official added.
The private firm is able to use 80 per cent of the construction waste and needs to add only 20 per cent of cement to produce footpath tiles.
“The quality of products that are made using recyclable material have been tested and verified by the CRRI. They are as good as those that are made using normal construction material,” the official said.
