Project Abstract

Construction and demolition activities have a significant impact on the environment, society, and economy. This research project aims to explore and analyze the multifaceted effects of construction and demolition on various aspects of sustainability. The study will focus on quantifying the environmental footprint of construction and demolition activities, including energy consumption, air and water pollution, waste generation, and habitat destruction. Moreover, the research will investigate the social implications of construction and demolition, such as health and safety risks for workers and nearby communities, displacement of populations, and changes in the local landscape. The economic aspects of these activities will also be examined, including costs associated with resource extraction, transportation, disposal, and potential economic benefits from reusing materials and creating new infrastructure. Through a comprehensive literature review and data analysis, this project aims to provide a holistic view of the impact of construction and demolition on sustainability. By identifying key challenges and opportunities, the research will contribute to the development of strategies and policies to mitigate negative effects and promote sustainable practices in the construction and demolition sectors. The findings of this study are expected to have implications for policymakers, industry stakeholders, and the general public. By raising awareness of the environmental, social, and economic consequences of construction and demolition activities, the research aims to foster a more sustainable approach to urban development and infrastructure projects. Recommendations for improving waste management practices, reducing energy consumption, and enhancing worker safety will be provided based on the study results. Overall, this research project will advance our understanding of the complex relationships between construction and demolition activities and sustainability. By highlighting the interconnected nature of environmental, social, and economic impacts, the study aims to promote a more integrated and holistic approach to managing construction and demolition processes. Ultimately, the research findings will contribute to the growing body of knowledge on sustainable construction practices and help guide decision-making towards a more sustainable built environment.

Project Overview

INTRODUCTION

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.

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). ”
