[en] The escalating crisis of waste mismanagement underscores the need for innovative treatment strategies, highlighting the inadequacy of conventional evaluation methods in the face of evolving waste management techniques. This study introduces a robust tool applying two decision-making methodologies to an existing multi-objective optimization framework. This framework can assess various waste-to-resource transformation processes, which was applied to the case of mixed plastic waste management within the circular economy. It yielded a set of 16 Pareto optimal recycling pathways according to four competitive objectives. Here, this new decision-making tool is applied to those Pareto solutions using user inputs as weight parameters to systematically rank them according to criteria weighting. Eventually, its capability is tested by a sensitivity analysis, assessing the robustness of solutions.
