Abstract
An estimation model of household's waste which is available for local government to make plans of waste management was developed. The mass of household waste is estimated using household's final consumption expenditure, household's attributes, price of goods, and waste conversion rate. The model is a comprehensive multilayered model representing consumption structure. LES (Linier Expenditure System) model is applied to disaggregate the fmal consumption expenditure to expenditures of major consumption categories, and the multinomial logit model is applied to disaggregate the major consumption expenditure to expenditures of intermediate consumption categories, constant rate is used to disaggregate the intermediate consumption expenditure to the expenditures of small categories, and the expenditure disaggregated finally is converted to the mass of corresponding waste category. This model was applied to estimate the waste generation of Kyoto city using the census of household consumption, as a result, effectiveness of the model was proved through evaluating error in the estimation of kitchen garbage.
