| Research Abstract |
Accumulated plastic waste can generate spontaneous combustion. During spontaneous combustion proceeds in a large scale, it is externally difficult to notice the minor signs indicating the start of combustion inside the accumulated plastic waste. Spontaneous combustion was simulated in a furnace using plastic waste, and the temperature change and the intensity and quality of odorous gas were measured during the spontaneous combustion process. Plastic waste composed of a mixture of a variety of single plastic film was subjected to hot temperature environment as a model plastic waste. Both the odor generated from this model plastic waste and the odor generated from each single plastic were measured. As a result, it was found that, in the case of the waste as a single specimen, the odor intensity is increased and, in the aspect of odor quality, the ratio of the similarity index aldehyde/ammonia increased in the ignition process due to heat accumulation. In addition, when the waste of each individual plastic was burnt using TG-DTA under air and Nitrogen condition, the odor also showed a similar tendency to that obtained in the experiment for the mixture as a single specimen.
