抄録
This study aimed to investigate the actual existential scenarios of consumer goods possessed by people, specifically earthquake resistance of consumer goods in elderly-only households. A 'basic unit' of consumer goods focusing on elderly-only household units was developed in this study. A web questionnaire survey was conducted for household units in the Kansai region of Japan for inhabitants over 65 years of age. The principal questions were related to the quantity and type of consumer goods possessed and/or not used on a daily basis (unnecessary consumer goods). The results of the survey revealed that the total micro-material stock in household units was 1216 kg/housing unit. The average quantity of unnecessary consumer goods was 20.9%, and the average rate of earthquake resistance for all consumer goods was 35.4%. Case studies in two cities, Minami-Ise and Kobe, were conducted to estimate the quantity of potential disaster waste. In Minami-Ise, the potential disaster waste derived from consumer goods (12,400 t) is equivalent to 83% of the micro-material stock derived from consumer goods in the city; 54% of the disaster waste may be generated from household units alone. The results revealed that if the rate of earthquake resistance of consumer goods was 100%, 22.5% of the potential disaster waste may be reduced. The potential disaster waste derived from consumer goods was estimated at 430,000 t in Kobe. Areas with particularly prominent potential disaster waste derived from elderly-only household units were visualized using GIS.
