Abstract

Although landfills are among the most important structures for municipal waste disposal worldwide, they are sometimes less preferred due to their impact on people and the environment. This research examines the health, safety and environmental (HSE) factors affecting the municipal solid waste (MSW) landfilling process’s performance. Next, it prioritises these factors using the conventional AHP and fuzzy AHP methods. Based on the findings, three main sub-criteria were determined from the 26 sub-criteria, and the environmental, health and safety criteria ranked the first, second and third, respectively. Leachate permeation control, control of pollutant production and hazardous gas monitoring were ranked the highest in terms of relative weight. In the environmental criteria, leachate control, in the health criteria, pollution and in the safety-related criteria, hazardous gas control were ranked the first. In addition, leachate permeation control had the highest global weight. Overall, experts are recommended to pay more attention to environmental issues and prioritise controlling the environmental impact of landfills in their design, construction and operation. © 2025 World Scientific Publishing Europe Ltd.
