Clean India mission: Mandatory for CPWD, NBCC to use recycled portions of construction, demolition waste

New Delhi, Mar 28 (UNI) Taking another path-breaking initiative under the ambit of the Swachh Bharat Mission, the Ministry of Urban Development today said it is mandatory for Central Public Works Department(CPWD) and National Buildings Construction Company(NBCC) to use recycled construction and demolition waste in all their constructions. The Ministry issued a notification from the CPWD, making it mandatory for CPWD and NBCC to use recycled portions of construction and demolition (C & D) waste in their construction activities, if it available within 100 km from the construction site. The notification specifies that coarse and fine varieties of recycled concrete aggregate (RCA) and Recycled Aggregate (RA) derived from the C&D waste are to be used in lean concrete, plain concrete cement (PCC) and Reinforced Concrete Cement (RCC) used in construction, an official statement said. In this regard, the Bureau of Indian Standards (BIS) has revised the existing IS specification (IS 383) to IS 383: 2016 and specified that for load bearing structures, up to a maximum of 25 per cent of coarse and fine RCA can be mixed with PCC, and up to a maximum of 20 per cent of coarse and fine RCA can be mixed with RCC. For lighter, non-load-bearing structures using lean concrete, the entire amount (100 per cent) of coarse and fine aggregates of both RCA and RA may be used. States are also being advised to get similar notifications issued by their state works’ departments, and follow similar guidelines for construction. India produces approximately 25 – 30 million tonnes of Construction & Demolition (C&D) waste annually, of which less than 5 per cent is processed, the remaining being sent for dumping, adding to the already overburdened dumping sites and attendant problems. This notification is expected to go a long way in solving the problem of disposal of Construction and Demolition waste in India. It will also help address to a significant extent the projected shortage of nearly 14,000 crore tonnes of aggregates required for the housing and road sector in India in the coming years.
