Abstract. Municipal solid waste management is a critical issue that directly impacts public health, environmental quality, and economic viability. The municipality of Skikda exemplifies the limitations of conventional approaches, which struggle to achieve their objectives. To transition towards a circular economy model, the adoption of decision-support tools based on robust data is essential.
This paper reports on the implementation of a Geographic Information System (GIS). Our methodology was based on the creation of a relational spatial database, synthesizing administrative and field data. The analysis of the results was conducted using advanced spatial analysis tools, including Nearest Neighbor analysis to assess the distribution of collection points, the creation of buffer zones to define areas of influence or exclusion, Thiessen polygons to delineate optimal service areas, and Kernel Density analysis to map waste concentration hotspots.
The results of this spatial analysis lay the foundation for a new, optimized waste management service aligned with the principles of the circular economy for the municipality of Skikda. The study demonstrates how GIS and its analytical tools are indispensable for diagnosing the existing situation and planning a sustainable and efficient management system.
