Abstract :

The higher amount of buildings and infrastructures in India, number of construction and demolition (C&D) waste is increasing continuously. These wastes, if not completely recycled, will create the environmental problems. This research paper concentrates on the use of a system dynamics technique to develop a C&D waste recycling. The project is based on the recycling of the rapidly increasing construction and demolition waste. Through this process we want to take a step ahead, the idea of stopping illegal Dumping and ultimately save our mother Earth from destruction. The cost of recycled C&D solid waste resulting in reduction of overall construction cost.

The demolition is the most commonly pronounced word in the construction industry. As per the new building rules building should be demolished after its service period. Now-a-days the importance is given to sustainable and environmental friendly construction; there should be effective control of the demolition waste. The demolition waste can be reused for the construction. Construction and demolition (C and D) waste is defined as the solid waste generated by the construction, renovation, repair, alteration or demolition of residential, commercial, government or institutional buildings, industrial, commercial facilities and infrastructures such as roads, bridges, dams, tunnels, railways and airports. Construction and demolition waste is considered as high volume, low risk. It is commonly understood that this waste can be considered a resource, either for reuse in its original form or for recycling or energy recovery. Because of increasing waste production and public concerns about the environment, it is desirable to recycle materials from building demolition. If suitably selected ground cleaned appropriate industrial crushing in plants, these materials can be profitably used in concrete. Despite this, most Construction and Demolition waste ends up in landfills recycled aggregate and recycled sand that can be obtained. Further with the help of the obtained recycled material we intend to make various products such as concrete, paver blocks, hollow blocks, etc which will in turn be less costly as well. These recycled materials and products made from it are economical without any considerable change in the strength and durability aspect. Not only the cost effectiveness but it will also be aesthetically pleasing. According to Metropolitan region development authority the amount of construction and demolition waste (C&D waste) must be reduced by at least 70%. 3Rs model (Reduce, Reuse and Recycle) in the C&D waste management with costs savings.

 This paper finds a broader understanding of the socioeconomic implications of waste management

over time and the positive effects of these policies in the recycled to achieve the goal of C&D waste as well as the

composition of Construction and Demolition waste, the need for its recycling and options that can be implemented for its efficient use in the field of concrete technology.

Key Words:  C & D waste; sustainable construction systems, Recycling, Concrete.
