Abstract: This study was performed to investigate the characteristics of pollutants and microbial communities obtained in simulated lysimeters and to evaluate the effects of anaerobic sludge and water on the biodegradation of swine carcasses. The leachate production rates of Lysimeters 2 and 3 with the addition of anaerobic sludge were higher than that of Lysimeter 1 (control). The methane production rate of Lysimeter 3 with anaerobic sludge addition and increased water content was higher than those of other lysimeters. The result of microbial community analysis revealed that the relative abundances of Proteobacteria including pathogens in Lysimeter 3 were lower than those in other lysimeters. Overall, this study demonstrated that the proper operating conditions of lysimeters accelerated the stabilization of swine carcasses and could contribute to sustainable land use.
