Household waste management is currently a major environmental challenge for all local authorities in Morocco. This study aims to evaluate the use of a new decision-making method—the analytical hierarchy process (AHP), which is based on matrix calculations—to select the most suitable waste management system for the Khenifra region of Morocco. A management system appropriate for the context of the region is suggested from a sustainable development perspective. Firstly, several schemes are examined and analyzed by applying the AHP method, which consists of a multi-criteria analysis of parameters and constraints linked to financial, technical, environmental, and socioinstitutional aspects. Secondly, five alternative management systems are compared and classified according to their performance levels and efficiencies. The results obtained using the complete priorities vector show that system 3 is the most appropriate household waste management scenario for this region, because it receives the greatest appreciation in all decisions made by the decision maker. The selected system (waste sorted at source, recycling–composting) follows the 3R principle (recycle, reduce, and reuse) and provides better control of integrated household waste management while respecting the environment and taking into account the conditions in developing countries. The multi-criteria analysis method and the evaluation criteria processing procedure proposed in this study provide decision makers with recommendations for the future of integrated household waste management in the Khenifra region in particular and developing countries in general.
