Analysis of Operational Parameters in a Municipal Landfill – Case Study

This paper presents an integrated analysis of the operational parameters in a municipal solid waste landfill, based on a representative case study. Unlike traditional approaches that address waste management processes separately, this study investigates the interdependence between key operational variables, including leachate level and flow, biogas production, internal temperature, waste density, and slope stability. A mathematical modelling framework is developed to describe the relationships between biological, hydraulic and mechanical processes that take place within the landfill. The results highlight significant seasonal variations, showing that the increase in temperature increases biogas production, but also leads to greater leachate generation and accumulation. This, in turn, negatively affects the stability of the slope due to increased pore pressure. The study reveals a critical trade-off between operational performance and structural safety, highlighting the need for integrated monitoring and control of waste management processes. A synthetic performance indicator is proposed to assess the overall behavior of the system and identify critical operating conditions. The findings contribute to a better understanding of landfill dynamics and provide practical support for optimising operational strategies, improving environmental protection and reducing risks associated with landfill operation.
