Abstract: The primary issue facing the municipality of San Francisco, Cebu, Philippines, is the treatment of Municipal Solid Waste (MSW); failure to do so would divert attention from the tourism sector, which is the municipality’s primary source of income. Thus, this study covers the identification of sustainable waste treatment through ranking using fuzzy AHP and TOPSIS as well as the cause-and-effect factors of municipal solid waste management using fuzzy DEMATEL. In this study, various commonly used municipal solid waste alternatives and factors are investigated. Five waste alternatives are selected such as anaerobic digestion, composting, incineration, recycling, and landfill and the solid waste management factors are technical, socio-cultural, cost, environmental, land required, and time required. The findings in fuzzy DEMATEL show that the environmental and land requirement are the effect factors in solid waste management, while the technical, sociocultural, cost, and time requirements are the cause factors. Anaerobic digestion ranked first, composting came in second, and recycling came in third. These results show that the most sustainable waste treatment options in fuzzy AHP and TOPSIS are based on ranking. The results of this study would be useful in prioritizing factors and choosing the most suitable plan of action for municipal solid waste management. All parties involved, such as government agencies, civic associations, and the general public, would be able to understand the various techniques and tools used in the study and hence make judgements.
