The impact of construction and demolition (c&d) landfills: emerging public and occupational health issues

Thesis Abstract

Abstract
Construction and demolition (C&D) landfills play a crucial role in managing the waste generated from building and infrastructure development projects. However, the operation of these landfills can have significant implications for public and occupational health. This research project aims to explore the emerging health issues associated with C&D landfills and their impact on both the general population and workers in the construction and waste management industries. The study will investigate the potential environmental contamination resulting from leachate and gas emissions at C&D landfills. Leachate produced from the decomposition of waste in landfills can seep into the surrounding soil and water sources, leading to the contamination of groundwater and surface water bodies. This can pose serious health risks to nearby communities through the ingestion of contaminated water or exposure to polluted soil. Similarly, the release of gases such as methane from landfills not only contributes to greenhouse gas emissions but also presents health hazards to individuals living or working in the vicinity of these sites. Furthermore, the research will examine the occupational health concerns faced by workers at C&D landfills. Employees involved in waste sorting, disposal, and landfill maintenance are exposed to various physical, chemical, and biological hazards on a daily basis. These hazards include heavy machinery accidents, exposure to toxic substances, respiratory issues from airborne particles, and the risk of infectious diseases. The study will assess the prevalence of work-related health problems among landfill workers and explore potential strategies to mitigate these risks through improved safety protocols and training programs. In addition to environmental and occupational health impacts, the research will also investigate the social implications of C&D landfills on surrounding communities. Issues such as noise pollution, traffic congestion, and decreased property values can affect the quality of life for residents living near these sites. Understanding the full range of health and social consequences associated with C&D landfills is essential for developing effective policies and regulations to protect both public health and the well-being of workers in the waste management sector. Overall, this research project seeks to raise awareness of the emerging public and occupational health issues linked to the operation of C&D landfills. By identifying and addressing these challenges, stakeholders can work towards promoting sustainable waste management practices that prioritize human health and environmental protection.
