【 摘 要 】

In order to know the risk of fire of disaster waste, radioactive waste and recycled materials, thermal analysis and gas emission test were conducted. Huge amount of disaster waste and radioactive waste were produced after the Great East Japan Earthquake (March 2011). During recovery work, we experienced many fires and accidents due to spontaneous ignitions from massive disaster and radioactive wastes. Some of wastes should be recycled for biofuel and constructive materials. To know the risk of ignitions and fires, we conducted risk evaluation for these materials using high sensitive calorimeters and gas emission. The investigation process and results are shown. Microorganism in the wastes caused faint heat generation which might be a trigger of fires. However disaster wastes are much safer than most solid biofuel, because disaster wastes contained large amount of incombustible materials.
