This study investigates the settlement behavior of Municipal Solid Waste Fines (MSWF) retrieved from varying depths of a dumpsite, assessing their application in foundation engineering. Using Finite Element Method (FEM) analysis, the settlement responses of MSWF-based foundations are evaluated. The research reveals diverse settlement patterns influenced by MSWF properties such as unit weight (ranging from 16.06 to 16.58 kN/m3) and secant modulus (from 1150 to 2900 kN/m2). A significant decrease in settlement was observed, notably from 7.56 cm at the surface to 1 cm at a depth of 10 m under staged loads of 10, 20, and 30 kN/m2. This study highlights the potential of MSWF as a foundation material, emphasizing both its mechanical stability and chemical implications. It contributes to sustainable construction practices by promoting the responsible reuse of hazardous waste materials, particularly in environments where they are least exposed to the open environment.
