Evaluating Sustainable Waste Collection Models Using the Analytical Hierarchy Process (AHP): A Multi-Criteria Decision-Making Approach

The growing issue of disposable baby diaper waste requires an effective collection model to support sustainable waste management. This study designs a community-based collection model using the Analytical Hierarchy Process (AHP) method to identify the most effective approach. Three models are evaluated: Model 1 (Community-Based Diaper Bank), Model 2 (Scheduled Diaper Pick-Up Program), and Model 3 (Diaper Collection Points at Public Facilities). Results show Model 1 is the most effective, with the highest Global Priority score of 0.415, due to its contributions to reducing environmental impact, raising public awareness, and incentivizing participation. Model 2 and Model 3 follow with scores of 0.353 and 0.261. The environmental criterion holds the highest weight (0.504), emphasizing its importance. These findings suggest that community-based models can enhance waste collection efficiency and support sustainability. The results can inform policy development and help guide future research on sustainable waste management practices.
