Abstract

<p>It has been pointed out that the 3Rs of disaster waste, which include not only securing treatment capacity and advanced recycling, but also reducing the volume of disaster waste, are indispensable for disaster waste countermeasures in the event of national disasters such as the Nankai Trough Earthquake and an earthquake directly under the Tokyo metropolitan area. On the other hand, Japan has declared its goal of becoming carbon neutral by 2050, aiming to reduce greenhouse gas emissions by 46% from the fiscal 2013 level by the year 2030. In the event of a disaster, CO2 emissions are expected to be generated in the process of disaster waste treatment, such as incineration, transportation, and CO2 emissions from the fixed carbon in the wood used in houses. The purpose of this study is to develop a method for estimating CO2 emissions from the treatment of disaster waste from the demolition and transportation of houses damaged by housing damage, and to estimate CO2 emissions from the treatment of disaster waste for the 2016 Kumamoto earthquake. The results showed that the transportation of disaster waste contributes significantly to CO2 emissions from the treatment of disaster waste.</p>
