Abstract: The management of municipal solid waste (MSW) is a global challenge of a complex nature. The organic fraction of rapidly degrading MSW, which can be recycled via composting provided it is segregated at the source, is an incipient or non-existent practice in low- and middle-income countries. This study aimed to identify the barriers and opportunities for composting MSW based on the perception of local stakeholders through a qualitative and quantitative exploratory case study in the municipality of São José dos Campos (SP). The study identified and interviewed local stakeholders engaged in composting in the territory, surveying the local market for organic agricultural inputs. Education, infrastructure, and social influence were the main factors that led to the decision to start composting. For home composting, the efficiency of generated waste diversion is from 42% to 59%, and management difficulties at the beginning of the practice are recurrent. Engaging people is the main challenge of community initiatives and 32% ended their composting activities due to the COVID-19 pandemic. Vermicomposting can be an opportunity to value organic waste in the local market. The insights gleaned from the perceptions of local stakeholders provide valuable input for more effective planning within a municipal composting scheme.
