Abstract: Migrated Rohingya community in southeast Cox Bazar in Bangladesh is experiencing poor or absence of waste management. An intensive questionnaire survey covered around 0.85 million migrants to observe the existing waste management practices. The selected area comprises of Ukhia, Kutubpalong mega camp, Gundum, Balukhali Bazar and Phalungkhali. The geospatial technique was applied based on three selected criteria, vis., social, economic, and physical. Physical measures include land use, soil type, geomorphology, slope, and drainage datasets from secondary sources. Secondary and primary data sources cover the social and economic criteria, i.e., population and their residence from both the road and drainage networks. The study's findings suggested that gender biases exist regarding awareness of poor waste management. Finally, to ensure green community, an overlay weightage approach was adopted using the geospatial technique; the study area was classified based on suitable dumping site as very high (0.09%), high (0.05%), medium (0.34%), low (17.96%) and very low (81.55%). This is envisaged that the acquired suitable waste dumping site map would provide relevant information to the adjacent community and the service provider.

Keywords: waste management; dumping site; overlay weightage.
