Abstract

This study presents a comprehensive Multi-Criteria Decision-Making (MCDM) framework, enhanced bythe Taguchi approach, to evaluate and prioritize wastemanagement strategies for accomplishing a “Clean Province”initiative. The research concentrates on critical aspects ofenvironmental sustainability, emphasizing waste managementand its impact on ecosystems, public health, and resourceconservation. Six essential criteria—source-level wastesegregation, reduction of waste generation, efficient collectionby local administrative organizations, adherence to academicwaste disposal standards, management during epidemics, andeffective handling of plastic waste—serve as the foundation forevaluation. Preference Ranking Organization Method forEnrichment Evaluations (PROMETHEE), Technique for OrderPreference by Similarity to Ideal Solution (TOPSIS), andAnalytical Hierarchy Process (AHP) are all incorporated intothe proposed framework. AHP determines the relativesignificance of criteria, whereas TOPSIS and PROMETHEErank strategies according to their proximity to ideal solutionsand preference flows, respectively. The Taguchi approach,which implements the “smaller-the-better” principle forranking strategies, further fortifies the analysis’s robustness,guaranteeing consistent and dependable evaluations. The resultsindicate that this framework is effective in identifying the mosteffective waste management strategies, thereby contributing tothe overarching objectives of environmental sustainability andresource efficiency. These results emphasize the significance ofstructured decision-making in addressing solid wastemanagement challenges, which have implications for wastevalorization, reuse, and recycling practices. This researchemphasizes the integration of waste-to-energy technologies andsustainable approaches to waste reduction, providingpolicymakers and stakeholders with actionable insights. Thisstudy provides a replicable model for improving solid wastemanagement systems, thereby assuring societal well-being andecological balance, in accordance with the objectives ofenvironmental science and development.
