The Central Pollution Control Board (CPCB, 2016) defines the construction and demolition waste (CDW) as ‘waste generated from the construction, repairing, remodelling or demolition of building etc. which include waste materials, soil, debris etc.’. The CPCB has estimated solid waste generation in India to be around 48 million tonnes per annum of which the construction industry accounts for approximately 25%, i.e. 12 million tonnes per year (TIFAC 2015). However, the Ministry of Urban Development (MoUD) India estimated that the Indian construction industry generates about 10–15 million tonnes per year. The estimates given by CPCB and MoUD are outdated. The waste generation rate (WGR) is considered as a significant factor in decision making and waste management (Lu et al., 2011). Ram and Kalidindi (2017) demonstrated WGR method to estimate the CDW in India under limited data availability. The usages of the WGR method is to predict the quantity of demolition waste (DW) produced from the demolition work, predicting fees and number of trucks required for disposal (Yuan and Shen, 2011). |
