It is encouraging to see that almost all respondents
think that waste generation should be reduced. It is a good
sign for the city of Bangkok that the residents perceive
MSW as a problem and are aware of its impact. The BMA
states that waste reduction should start with changing
people's behavior to generate the minimum amount of
waste. Moreover, other studies show that in Bangkok,
waste reduction is a sound MSWM method and is more
essential than landfills. In terms of waste management
service effectiveness, 55.9% of all respondents think that
they receive a moderate level of service. The survey results
indicate that the outstanding problems requiring urgent
solutions are (1) the odor from waste (68.5%), (2) leftover
waste (51.2%); (3) waste is not collected on time (39.1%), (4)
fallen waste during transport (31.8%), and (5) no waste
management service in an area (7.6%).
