Abstract
We propose a method of analyzing data obtained by household questionnaire surveys, employing quantification theory. Through the case study in Tokyo metropolitan area, we quantitatively analyzed the waste generation structure as well as the factors pertaining to the awareness and action of waste discharge.
It is important to predict the quantity of municipal solid waste in the future and be also to grasp the actual awareness of waste reduction for the waste management planning. Thus our proposed method consists of following three parts, i ) ; analysis of waste generation structure using quantification theory type-1, ii) ; classification of the factors relating to the awareness and the action for waste reduction with quantification theory type-3, iii) ; analysis of waste reduction awareness with quan-tification theory type-2. In considering the case study with the questionnaire data, our approach starts analyzing the waste generation structure in households, finding the factors which relate to quantity and then describing the forecasting model of the amount of waste generated from each type of household. Moreover we show the process to classify the factors of awareness and actions into four groups. Finally we describe the factors relating to the awareness of waste reduction.
