Abstract
Construction and demolition waste (C&DW) management is gaining attention from policy makers in India. This article estimates C&DW generation from urban building, rural building, and non-building sectors in India and calculates material, energy, and emissions savings from C&DW recycling. The method used in this study is top down up material flow analysis approach. The results indicate that India generated between 112 and 431 million tonnes of C&DW in 2016 depending upon the assumptions, which are orders of magnitude higher than official records indicate. Although per capita waste generation from rural area is less than urban areas, rural areas as a whole generate more waste than urban areas, as rural population is still over two times the urban population in India. Additionally, it was estimated that formal C&DW recycling can save upto 2–8% of natural minerals, such as sand and aggregate in urban areas, energy and emissions savings were negative, implying that recycled C&DW materials are likely to be more resource and environmentally intensive as compared to natural materials.

N.B. Descriptive scope is a count of how many of the five facets of empirical research are indicated by the words used in title, abstract and keywords. It is not intended as a judgement on the research; merely a count of the kind of word we would expect to indicate Phenomenon, Concepts, Theoretical framing, Empirical techniques, Analytical techniques. If all five are present, then a code of “5 PCTEA” will indicate this. If you feel the coding for this record is questionable, we welcome discussion around the terms we matched or the way we categorized them. The facet you would expect may not be coded, or a facet may be coded inappropriately. This can also bear on a larger question, of which facets should be treated as defining in construction management research. Please get in touch, and we will look at it. More details here
