One of the simple and affordable management techniques for getting rid of solid waste is landfill. It is employed in many places of the world. However, poor management and inefficient placement will cause environmental pollution and public health risks. Because of its improper location, the Ifo local government has long used an open dumping system that is neither ecologically friendly nor socially acceptable. This study's primary goal was to find a suitable location for the disposal of solid waste utilizing cutting-edge technology to ensure environmental sustainability and public health protection. The research area's landfill was chosen based on factors such land use and land cover, slope, water body drainage patterns, roads, etc. The geospatial decision-making process was carried out using a GIS-based Multi-Criteria Evaluation approach. To determine the external and internal weight values for each class inside each criterion and for all criteria, a pair-wise comparison module of Analytical Hierarchy process (AHP) was used. An overall land fill suitability map was created by combining the criterion maps using weighted linear combination. As a result, of the entire research area, it was determined that, in that order, 48.1km2 (10.2%), 58.1 km (12.07%), 25.5 km (5.3%), and 369.7 km (76.8%) were very, moderately, marginally, and un-suitable for disposal.
