Preparations for a disaster, such as formulating a disaster waste disposal plan and business continuity plan, can allow for the earliest possible response to disaster waste following any incident. To maintain effectiveness, it is necessary to accurately estimate the amount of disaster waste and formulate a waste disposal plan. Our group has researched such information based on maps and satellite data that can identify areas with many artificial structures in order to calculate the estimated number of buildings from the estimated population density. We conducted a case study where we estimated the total floor area by multiplying the number of buildings with the unit area per household. This study shows the unit volume of disaster waste per area in selected cities throughout Japan, Shanghai, and Indonesia. When researching the unit volume of disaster waste for each building structure typology in other Asia-Pacific countries, we found it is possible to estimate the potential amount of disaster waste generated by multiplying the total floor area with the unit volume.
