A survey to characterize municipal solid waste in Hoi An, a famous world heritage city in Vietnam was carried out at household level. The purpose of this study is to identify generation rate and compositions of household waste from different type of areas of the city. The areas surveyed covered rural, urban and suburban, tourist quarters (Hoi An ancient town), presenting three typical types of urban in Hoi An. The result will contribute to consider harmonized solid waste management for the city. A stratified sampling method was applied for selection of household waste samples in order to evaluate differences between areas of the city in waste generation rate and composition. The following statistical results were obtained: overall mean of waste generation rate was about 0.223 kg capita-1day-1, ranged from 0.207 to 0.240 kg capita-1day-1for 95% confidence interval; the average waste generation per capita in tourist old town and urban area (0.203 and 0.264 kg capita-1day-1) was almost double that of rural area (0.12 kg capita-1day-1) and those differences was statistical significant. In addition, the study found that, degradable waste counted for more than half of amount of household waste (37.5% for Food and 14.17% for Yard waste) , Combustible waste (textile, leather, wood, diapers etc.) (13.23%) was highest portions in household waste composition, which mean that biological and thermal treatment technologies could be potential options with the purpose of declining amount of waste to landfill for the city . The result of research also showed that there are differences in waste composition among tourism and other areas, but those were not statistical significant.
