Sustainable Redevelopment by Reuse and Recycle of C&D Waste in Mumbai

Abstract

Solid waste that is generated due to demolition or alteration, any renovation work, structure repairing work is known as Construction and demolition waste (C&D). This waste is considered low risk waste but found in high volume. This waste can be used as resource for recycling and reusing. Due to increase in C&D waste environmental concerns and public health concerns are also increased. This causes necessity for recycling and reusing of C&D waste. If proper waste materials are managed, cleaned and sieved in industrial crushing plants materials can be reused. In spite of this demolition waste is dumped into dumping grounds of Mumbai. Mumbai Metropolitan Region (MMR) has nine municipal corporations which has area of 4,355sq.km. Under 74th Constitutional Amendment, Municipal Corporations in India are mandated to have solid waste management. In MMR all municipal corporations have centralized waste management that is dumped into nearby landfills. There are multiple players including informal sectors who are merging in managing C&D waste to decentralized the process. Due to increase in C&D waste in dumping grounds of Mumbai necessity to develop waste management plan is important. Working towards achieving this will help to reduce hazardous effect on humans and environment. This study highlights the need of reusing and recycling of C&D waste with proper management for sustainable development in city of Mumbai.
