Abstract
This review paper examines the critical issue of waste management in the construction industry, focusing on techniques for reducing and managing construction waste. It begins by highlighting the importance of waste management, outlining the significant environmental and economic impacts of construction waste, and setting the research objectives. The paper then categorizes the types of construction waste and identifies the primary sources and impacts of these wastes. Effective waste reduction and management techniques are discussed, including waste prevention, reuse, recycling, and sustainable construction practices. The regulatory and policy frameworks governing waste management are analyzed, focusing on international and local policies. Best practices for implementation, illustrated through successful case examples, are provided, along with the roles of various stakeholders. The impact of modern technologies and innovations, such as Building Information Modeling (BIM) and the Internet of Things (IoT), on waste management is explored. Finally, the paper addresses current challenges in waste management and provides recommendations for future improvements, emphasizing the need for collaborative efforts among industry stakeholders. Keywords: Construction Waste Management, Sustainable Construction, Waste Reduction Techniques, Building Information Modeling (BIM), Recycling and Reuse.
