Pathways in Construction to Deliver SDGs 11, 12 and 13 Waste Management for the Built Environment: Unlocking the Circular Economy
摘要
The effective management of solid waste generated from civil works and industrial activities is essential for promoting environmentalSustainability sustainabilityEnvironmental sustainability. This chapter addresses challenges in the actualization of three Sustainable DevelopmentSustainable development GoalsSustainable Development Goals (SDGs)—SDGs 11, 12 and 13—by integrating solid waste into the construction sector, thereby advancing green constructionGreen construction practices. It supports achieving the Sustainable DevelopmentSustainable development GoalsSustainable Development Goals (SDGs), particularly goals 11 on sustainable cities and communities, 12 on responsible consumption and production and 13 on climate action. This chapter further explores circular waste managementCircular waste management strategies that convert various waste streams, including industrial byproducts, construction and demolition residues and selected municipal solid waste, into functional construction materials. By positioning the construction industry as a significant end user, the study evaluates material performance, environmental benefits and challenges associated with practical implementation. Life cycle assessments and technical analyses reveal substantial reductions in greenhouse gas emissions, resource depletion and landfill pressure. The study highlights the importance of regulatory support, innovation in waste-processing technologies and stakeholder collaboration in facilitating the transition to a circular economyCircular Economy (CE) in the construction sector. The findings provide a scientific foundation for resource-efficient, climate-resilient and sustainable built environments.
