Imparting an ugly sight to the cityscape, piled up construction debris have for long been a major challenge for the civic administration here. As the city grew and construction activity picked up in the last two decades, absence of a prescribed disposal practise had builders dumping the pulled down masonry work, bricks, timber and iron pieces along major road corridors and most open spaces across the city.

Hyderabad, which suffered the ignominy of finding itself placed at 275 place in the recent Swachh Bharat rankings, is now all set to come up with its first Construction and Demolition (C&D) waste management project. In its bid to find a sustainable solution for construction and demolition waste management, the Greater Hyderabad Municipal Corporation (GHMC) has initiated steps for setting up of a facility where this waste could be processed and recycled. Estimates suggest around 500 tonnes of C&D is generated per day, most of which ends up indiscriminately strewn across the city. The municipal corporation has taken a decision on putting in place practices in collection and processing of the construction debris under Public Private Partnership (PPP) mode. Accordingly the selected agency would be provided land, most probably at Borabanda, to set up the required paraphernalia.

“About 30 points in different parts of the city will be notified as places where the C&D waste has to be dumped. This will help in preventing the indiscriminate dumping by the builders,” said an official. The selected agency would pick up this waste from the designated points and shift to its processing and recycling unit.

“This waste could be processed and used for different purposes and to make footpath tiles, kerbs, filling of basements and so on. The agency will have the responsibility of screening the collected material and after processing, use it to recycle,” said the GHMC Additional Commissioner (Health and Sanitation), N. Ravi Kiran.

The waste has been classified into categories of Claimed C&D waste generated in bulk and where the builder could be identified, and Unclaimed C&D waste which is dumped surreptitiously, mostly by individual house owners taking up construction and repairs. “The selected agency can lift the Claimed C&D waste from bulk generators and collect a tipping fee,” he said.

Once shifted to the processing facility, the debris would be washed to minimise dust generation and based on technology to be adopted, crushed, screened and separated. On recycling, the selected agency would be authorised to sell the recycled product i.e., tiles, fillers and kerb material in the open market.
