Global positioning system (GPS) technology is applied to the management and control of waste collection. To deal with the growth of the population and the consequent in- crease in waste, to increase the efficiency of waste management service, and to ensure the city's cleanliness, the BMA has set a budget of 5 billion baht for waste collection and disposal in 2015. Collected waste is weighed at waste disposal stations and the data is then recorded and transferred to the central database of the DoE on a real-time basis. This enables all responsible persons to access the information anytime through each district's computer system. The efficiency of a waste management system depends on many factors, including collection routes, amount of waste, transport distance, traffic conditions, collection methods, number of trips, weight per trip, and treatment methods. As mentioned earlier, it is clear that MSW contributes to severe environmental problems, and waste management technology has recently ceased to evolve. Although the BMA has performed well overall in Bangkok, there are some areas in which waste management services have failed to respond to the growing amount of waste. If technology remains unchanged, additional resources to manage the generated waste are needed. In terms of a sustainable and effective waste management system, it is important to take into account the importance of technology.
