Management systems and techniques are currently being developed to decrease the environmental burden of waste generation, but there is still a need to provide a sustainable waste management system that effectively supports resi- dents. It is essential to apply appropriate technologies to waste management systems. In this paper, the objectives are to identify the technological challenges facing the cur- rent MSWM system and to overcome the technological gaps in Bangkok, Thailand as a representative urban city in a developing country. Technological gaps in management processes are one of the main causes of poor performance in waste management systems. To identify the success factors for a sustainable MSWM technology transition, the paper is aimed to incorporate human aspects of technology for MSWM by investigating service providers and service recipients' experiences and attitudes of MSWM.
