services in Thailand, especially in Bangkok, and which
factors have an impact on the effectiveness of MSWM.

services and opinions on the performance or
utilization of the technology were asked. Depending on the
experts' knowledge and experience, the interview then led

the MSWM system could run successfully with these
technologies. The last question posed to interviewees was

why MSWM in Bangkok should have a
sustainable MSWM system, what the essential factors are,
and who should be involved in the system. Moreover, in
terms of achieving a sustainable waste management service,
questions like who should be involved in the MSWM
process, the roles of stakeholders, and the chances for
