Solid waste management is a process that involves the collection, processing, recycling, refuse, reuse and disposal of waste to protect public health and ensure environmental sustainability in a longer run. In Bangladesh, rapid urbanization along with limited waste-management infrastructure have caused significant challenges, resulting in large portions of municipal waste being unmanaged or disposed of in open dumps. This study investigates the challenges of solid waste management in Narayanganj City Corporation (NCC) using a mixed-methods approach. A sample of 138 participants was selected based on a 99% population proportion. The results identify key issues in solid waste management within NCC and provide a foundation for future research. A regression model incorporating five independent variables was analyzed using STATA 14. Disposal location (p = 0.000) and timeliness (p = 0.040) were significant at the 99% and 95% confidence levels, respectively, demonstrating strong associations at P <= 0.01 and P <= 0.05. The p-values indicate an absence of multicollinearity in the model. Qualitative analysis further revealed challenges, consequences of mismanagement, and the procedures involved in waste management.
