What is C&D waste? As per the Construction and Demolition (C&D) Waste Rule 2016, ‘any waste comprising building materials, debris and rubble resulting from construction, remodeling, repair and demolition of any civil structure’ is classified as C&D waste.
Wastes also include surplus and damaged products and materials arising in the course of construction work or used temporarily during the course of on-site activities. Some municipalities also include debris recovered from desilting of drains and waterbodies in C&D waste.
Characteristics of the waste C&D waste is an inert waste, over 90 per cent of which can be easily reused or recycled. A study by Technology Information, Forecasting and Assessment Council (TIFAC) in 2001 noted that C&D waste in India typically contains soil, sand and gravel (36 per cent), bricks and masonry (31 per cent), concretes (23 per cent), metal (5 per cent), wood (2 per cent), and others (3 per cent). But the composition of C&D waste varies from region to region, depending on prevalent construction style and building material usage. There is no exhaustive study on regional variation in C&D waste composition.
