It is very important to treat infected livestock carcasses safely and quickly. In this study, the degradation characteristics and odor generation characteristics of carcasses were investigated during the treatment of swine carcasses using the anaerobic burial composting method. While the carcasses were decomposed, the temperature remained high, at 4055C on average, and most of the carcasses were decomposed rapidly. The major odorcontributing substances in the buried composting method are sulfuric odor substances such as H2S, CH3SH, dimethyl sulfide (DMS) and dimethyl disulfide (DMDS), and the odor contribution of these substances is 9399%. Among them, CH3SH, which accounts for about 5689% of odor contribution, was the most representative indicator substance. Despite the anaerobic digestion process, the methane concentration in the digestion process was as low as 0.50.8% at the burial point of the carcass. The odor and methane produced during the decomposition of the carcasses decreased considerably during the discharge to the surface layer through the buried layer consisting of compost. These results suggest that anaerobic high temperature burial composting is one of the most useful methods to treat carcasses of infected livestock.
