Assessing the role of preparation for reuse in waste-prevention strategies by analytical hierarchical process: suggestions for an optimal implementation in waste management supply chain

Reuse is one of the most important waste-prevention strategies. Although the importance of preparation for reuse is clear, preparation centres for reuse are not common in the traditional waste management supply chain. An analysis of their contribution in waste-prevention strategies is therefore needed. Our research evaluates three preparations for reuse scenarios in municipal solid waste management with an analytic hierarchy process (AHP). These alternatives were assessed with three criteria: economic, social and environmental. Sensitivity analyses were performed to study the impact on the final ranking of changes in various parameters. Results highlight that the best alternative is to include the preparation for reuse in the waste management supply chain, with a moderate recourse to it. The study sheds light on how managers can better plan preparation for reuse activities and provides new trajectories for future research.
