Environmental and Structural Implications of Sustainable Construction and Demolition Waste Management

The construction industry is a major contributor to global solid waste generation, with significant consequences for both the environment and the built environment. This paper provides a comprehensive overview of the environmental and structural implications associated with construction and demolition (C&D) waste. We examine the negative environmental impacts of improper waste disposal, such as resource depletion, landfill overflow, pollution, and increased greenhouse gas emissions. The paper also delves into the structural consequences of using recycled aggregates and other repurposed materials, addressing concerns regarding long-term durability, strength, and overall performance. By synthesizing current literature and best practices, this paper aims to highlight the critical need for effective C&D waste management strategies, emphasizing the "3Rs" (reduce, reuse, and recycle) and other advanced techniques. We conclude by outlining future research directions to promote sustainable construction practices that mitigate environmental harm without compromising structural integrity.
