A Sustainable Approach towards the Construction and Demolition Waste

Shishir Bansal, S K Singh

With the growth of society on all the fronts, lot of construction activities are seen everywhere. Mega construction activities are increasing exponentially. Also, the demolition of existing structures, which have outlived its service life, is going on simultaneously. It is not essential that the structures need to be demolished only after their service life span is over, but also due to ongoing trend of reconstruction of even healthy structures just for creating more space in order to meet the present requirement. All such activities are generating huge amount of waste, called the Construction and Demolition (C&D) waste. Disposal of such debris in a sustainable manner is a big challenge for the builders, developers and owners. While the disposal of debris is a challenge, on the other hand there is an acute shortage of naturally available aggregates for construction of buildings. Reduction of this demand in a small way is possible with the reusing or recycling of construction and demolition waste generated from the construction activities. Hence, the construction sector must accept the use of C& D waste wherever feasible
