State-of-the-art on Recycling of Construction and Demolition Waste in a Circular Economy: An Approach Towards Sustainable Development
The exponential growth of global population, economic development, and urbanization has demanded more infrastructure and utilities, causing the accumulation of a large volume of construction and demolition (C&D) waste and subsequently increasing pressure on natural construction materials with a high depletion rate. Various research studies have proven that C&D waste has enormous potential to use it as construction materials. Across the globe, the recycling rate of C&D waste is varying from 5% to 95%; worldwide, the current economy towards C&D waste management is not in a favorable position, mainly raising more demand of the raw materials, the construction the sector needs to take serious measures on fulfilling the demand gap of raw materials and increase resource efficiency. The development of technology to recycling of C&D waste as secondary materials can supplement natural construction materials and would be a viable solution to eliminate environmental pollution, alleviate the problem of waste, and meet the demand for construction materials. Worldwide at present generation of C&D waste is almost 10 billion tonnes, only 9% is recycled, and rests have remained as the unmanaged condition. To promote recycling facilities of C&D waste on a large scale, policymakers, and Government authorities should be informed about various options and the scope of the recycling and valorization of C&D waste. This paper describes the present state of the art of recycling and valorization opportunities of C&D waste through the circular economy principle, leading to replenishing the depletion of natural construction materials and increasing the sustainability of the natural resources.
