摘要：Solid waste generation rate plays an important role in calculation and design different elements of amunicipal solid waste management system of an urban area. The survey was carried out at 644households living in 6 selected wards of 6 districts in Ho Chi Minh City (HCMC) that have differentpopulation densities to determine generation rates and main composition (food refuses and plasticbags) in domestic solid waste. Composition of household solid waste of HCMC determined from thisstudy will help to develop a model to predict solid waste generation rate in the future. It is also foundfrom the study that, in 2015 household solid waste generation rate of HCMC is 0.41 kg/capita/day (SD= 0.313), food refuse generation rate is 0.23 kg/capita/day, plastic bag generation rate is 0.032 kg/capita/day, and percentages of food refuses and plastic bags in domestic solid wastes of HCMC are61.63% and 7.67%, respectively. Statistical data indicate that generation rates of household solidwaste, food refuses, and plastic bags are inversely proportional to the number of people in a familyand directly proportional to the household income. The rank correlation shows no significance betweenthe household solid waste generation rates and the urbanization levels as well as between householdsolid waste generation rates and days of a week. A linear regression model proposed to determinegeneration rates of household solid waste, household food refuse, and household plastic bagsshows that household size and household income explain only 14.2% of solid waste generation rate(R2 = 0.142) and 11.9% of plastic bag generation rate (R2 = 0.119). Generation rate of food refuse(within the scope of this study) can only be estimated based on household size (R2 = 0.08).
