Abstract:
Due to rapid urbanization, there is a continuous trend of an upsurge in building activities in India. Owing to this, India has started to face, a rapid increase in the amount of iConstruction & iDemolition iwaste. In our country, CDW amounts to 1/3rd of the total waste generated. Lack of accurate data about the debris generation is making its proper management quite tough for the administration. The lack of a systematic collection and disposal system for construction industry constituents is jeopardizing the waste management of many cities of India. In India, there is less recycling facility/ plant to process Construction and Demolition waste. Most of the Indian cities would have had the infrastructure to manage waste if 2016 construction & demolition waste rules were followed. The haphazard dumping of debris in unauthorized areas affects the environment adversely. Impacts on the environment which are generally observed are air, water, soil & visual emission, flooding instigated by contraction of river boundaries. There is also an increase in the number of diseases such as respiratory issues. Most of these issues are prevalent in Gurugram. Gurugram, a satellite town in NCR where rapid urbanization is happening, is still lacking in Construction & Demolition waste management. This lack of management is leading to air pollution & flooding. Gurugram had only 3 good air quality days in 2018 & the dust from construction & demolition waste contributed to about 30 percent of the city pollution. Source: (CSE, 2019) & (HSPCB, 2018) This thesis reviews present CDW / Debris management practices and justify the urgent requirement of a green tactic for reducing negative externalities of CDW in Gurugram. This can be achieved by the establishment of mobile CDW plants, new collection centers, suitable routes, controlled construction activities in the buffer area of hotspot zones. The Installation of wind barriers according to the wind pattern, removal of encroachments on natural entities, use of modern technologies (Blockchain technology), use of mechanized cleaning, prefabricated structures, recycled debris & enhancing the usage of 3Rs concept (Reduce, reuse & recycle), will greatly reduce potential environmental impact .
