The government has issued an advisory directing that the use of recycled construction waste be made mandatory in all civil and construction work in Delhi by private and government agencies.
In all government projects costing more than Rs 500 crore, there may be a provision for installation of construction and demolition waste-processing plant of appropriate capacity, according to the advisory issued recently.
All government agencies have been directed to include a clause in their tenders that mandates use of minimum of 2 per cent processed or recycled products from construction waste in all future contracts for building work, and 10 per cent of recycled products from construction waste for road work.
Delhi generates over 4,000 tonnes of construction and demolition waste every day. A majority of the waste gets dumped in low lying public land, along the roads and ridge or the Yamuna river bank, creating civic and environmental problems for the city. Apart form occupying urban land, drains are choked leading to flooding.
“Reuse and recycling of construction waste will ease this problem. Processing of waste has great potential to save urban spaces, reduce negative environmental impact, conserve natural resources and address the shortage of building materials,” said a senior government official.
“The National Green Tribunal has directed no construction waste be dumped on the banks of Yamuna. It is to be processed scientifically at authorised recycling facilities. Agencies have been sending this waste to a plant in Burari,” he said.
