Circular Economy Strategies for Construction and Demolition Waste Management: Environmental and Economic Impacts in Urban Construction Projects


Abstract

The construction industry generates substantial quantities of construction and demolition waste (CDW), creating significant environmental and economic challenges in rapidly urbanising regions. Circular economy (CE) strategies have emerged as effective approaches for minimising waste generation, maximising resource recovery, and promoting sustainable construction practices. This study examines the application of circular economy principles in construction and demolition waste management and evaluates their environmental and economic impacts on urban construction projects. The research explores key CE strategies, including waste reduction at source, material reuse, recycling, and resource recovery, and assesses their effectiveness through a review of current practices and case studies. Environmental benefits such as reduced landfill disposal, conservation of natural resources, lower greenhouse gas emissions, and decreased energy consumption are analysed alongside economic outcomes, including cost savings, revenue generation from recovered materials, and improved project efficiency. The findings show that construction stakeholders can significantly enhance sustainability performance and achieve measurable economic advantages by implementing circular economy strategies. However, challenges related to regulatory frameworks, technological limitations, and market acceptance remain barriers to widespread adoption. The study concludes that integrating circular economy principles into urban construction projects offers a viable pathway toward sustainable waste management and supports the transition to a more resource-efficient and environmentally responsible construction sector.
