The construction and demolition (C&D) industry generates a significant amount of waste, primarily consisting of concrete, bricks, and other building materials. This waste poses environmental challenges and contributes to the depletion of natural resources. This abstract explores the innovative approach of utilizing construction and demolition waste as recycled aggregates in the construction sector, promoting sustainable building practices. Recycled aggregates derived from C&D waste offer a viable alternative to traditional construction materials, reducing the demand for virgin resources and minimizing the environmental impact associated with extraction and transportation. This paper examines the technical feasibility, environmental benefits, and economic implications of incorporating recycled aggregates into various construction applications. Key aspects discussed include the processing and treatment methods for C&D waste to obtain high-quality recycled aggregates, ensuring compliance with industry standards and regulations. The abstract delves into the performance characteristics of concrete, asphalt, and other construction materials containing recycled aggregates, addressing concerns related to strength, durability, and structural integrity. Furthermore, the potential reduction in greenhouse gas emissions associated with the production of recycled aggregates is highlighted, emphasizing the role of this approach in achieving sustainability goals. Challenges such as quality control, variability in waste composition, and acceptance in the construction industry are also addressed. The abstract underscores the importance of collaborative efforts among stakeholders, including government bodies, construction companies, and research institutions, to promote the widespread adoption of recycled aggregates in construction projects. In conclusion, this abstract advocates for paradigm shifts in the construction industry towards a circular economy by embracing the use of construction and demolition waste as recycled aggregates. By doing so, the industry can contribute to resource conservation, waste reduction, and the overall promotion of sustainable development.
