Abstract:
The construction industry has been growing very fast in recent years due to increase in industrialization, urbanization and the population, due to which the demand for construction activities is increasing. As a result, there is increased generation of construction and demolition waste. The Indian construction industry generates about 10-12 million Tons of waste annually. Thus, effective management of construction and demolition waste is need of the hour. The present study on “ Construction and Demolition Waste Management in Delhi NCR: A Stakeholder’s Perspective” aimed at studying the construction management practices, different types of waste generated on the construction site, the process of collection, segregation and disposal of waste on site and stakeholder’s perspective about reclaiming and recycling of construction and demolition(C&D) waste. The study revealed that the construction and demolition waste management planning was done at construction sites, there was huge gap in planning and the actual implementation of management practices. All the construction sites were generating similar type of construction waste and the amount of waste generated depends on the scale of operation and management practices. Further, it was seen that the C&D waste generated was segregated onsite largely by scrap dealers and supplied to material manufacturers, and waste recyclers. However, most of the rubble was either used to fill the excavated land or was dumped on open plots and road sides. The study has shown that the stakeholders had a positive approach towards recyclability and reclamability of C&D waste. Thus construction and demolition waste management onsite has scope for a lot of improvement. It is recommended that there should be stringent rules by government, mandating use of some percentage of materials made out of C&D waste in every construction project. Also incentives should be offered by government along with mandates to catalyse the process.
