Abstract
Construction and demolition activities have a significant impact on the environment, economy, and society. These activities generate large quantities of waste, consume vast amounts of resources, and contribute to pollution. The management of construction and demolition waste is crucial to mitigate the environmental impact and promote sustainable practices in the construction industry. This research project aims to analyze the impact of construction and demolition activities on the environment, economy, and society. The study will investigate the volume of waste generated, the types of materials discarded, and the disposal methods used in construction and demolition projects. Additionally, the project will assess the resource consumption, energy usage, and carbon emissions associated with these activities. The environmental impact of construction and demolition activities will be evaluated in terms of air and water pollution, land degradation, and resource depletion. The study will also examine the economic implications of waste management practices, including the costs of disposal, recycling, and potential revenue from recovered materials. Furthermore, the social aspects of construction and demolition activities will be considered, such as the health and safety hazards for workers and the community. The research will involve data collection from construction sites, waste management facilities, and relevant stakeholders in the construction industry. Quantitative analysis will be conducted to determine the amount and composition of construction and demolition waste, as well as the environmental and economic impacts of current practices. Qualitative methods, such as interviews and surveys, will be utilized to gather insights on social aspects and stakeholder perspectives. The findings of this research project will provide valuable information for policymakers, industry professionals, and the public to enhance waste management practices in the construction sector. By understanding the environmental, economic, and social implications of construction and demolition activities, stakeholders can develop strategies to reduce waste generation, promote recycling, and minimize the overall impact on the environment. Overall, this research project will contribute to the knowledge base on sustainable construction practices and provide recommendations for improving waste management in the construction industry. By addressing the challenges posed by construction and demolition activities, stakeholders can work towards a more sustainable and environmentally friendly built environment.

</p><p><strong>INTRODUCTION</strong></p><p>Historically, construction and demolition (C&D) debris landfills have been considered nonhazardous operations, containing relatively inert wastes such as concrete, asphalt, wood, metals, gypsum drywall, and roofing materials. In recent years, however, it has become increasingly clear that emissions resulting from the decomposition of gypsum drywall and organic debris are a public health issue. Drywall, comprised of gypsum (CaSO4 •2H2 O), breaks down into hydrogen sulfide and other sulfur compounds under anaerobic conditions and in the presence of water.</p><p>Overall, the good news is that C&D landfills are not known for being particularly dangerous to human health, though certainly they do come with their risks (Colledge & Wilder 2011). In each of the case studies from New York, Wisconsin and Virginia (mentioned above) where a C&D landfill was identified to pose potential health risks to the community, there were problems with the ENST 698, fall 2011 facilities that could have been prevented or fixed (United States Environmental Protection Agency Office of Solid Waste 1995). ”</p>
