The study identifies the barriers that have led to ineffective and inefficient solid waste management in Karachi. This qualitative study was done using the interpretivism approach. Structured interviews with individuals who belonged to governmental institutions, i.e. SSWMB, KMC, DMCs, and the Cantonment Boards of Karachi, were conducted. After using thematic analysis, the major factors affecting waste management were developed and categorized into 6 areas. This study reveals that there is a strong institutional framework, to run the operations. The major factors that led to ineffective solid waste management are inadequate infrastructure, weak strategic planning, and lack of commitment to the targeted task assigned, non-existence of proper fee collection, challan system, political influence, and non-delegation of authority. There is not much cooperation and participation of the general public, shopkeepers, commercial institutions, and hospitals, in solid waste management activities. This study further, determines Scavengers, Shepherds, Afghan and Builder mafias are major barriers to waste management activities in Karachi. The findings of this research will be useful for the stakeholders in decision and policy-making and will improve the solid waste management system
