Municipal corporations of small cities in India are struggling with the challenges that emerge from the unstructured solid waste management system. For successful implementation of the municipal solid waste management system, all the essential components of this system need to work effectively and efficiently. Identification of performance indicators is completed with the help of a literature review and expert information. Interviews were conducted with experts working in solid waste management, and three decision criteria, i.e., importance, performance, and understandability, were defined to evaluate the selected performance indicators. For uncertainties, criteria weights were established using the spherical fuzzy analytical hierarchy process approach, and the combined pair-wise comparison matrix was aggregated by applying the spherical fuzzy TOPSIS method. Eventually, the indicators responsible for sustainable waste management were selected and ranked. An assessment of the conceptual framework of MSWM is also proposed for practical implementation of the rated indicators for the MSWM system in Dinanagar and other cities with similar situations.
