In this study, municipal wastes were divided into household wastes and nonhousehold wastes, and household wastes were classified as waste in the standard plastic garbage bag, food waste and recycling waste. Units of household wastes with city size and dwelling type were estimated to manage the effective disposal of municipal waste and to improve a waste managing system. Results showed that a unit of the special city (Type A) was 341.1 g/day/person, 364.7 g/day/ person for the metropolitan city (Type B), 421.8 g/day/person for the small and medium sized city (Type C), and 366.5 g/day/person for the agriculture and fishery village (Type D). In the cases of household wastes with dwelling type, a unit of the apartment was 373.6 g/day/person, the row house was 395.4 g/day/person, the multiplex house was 415.8 g/day/person, the house in the non-residental building was 348.2 g/day/person, and the detached house was 389.9 g/day/person.
