The number of livestock and amount of livestock manure are steadily increasing in Korea. The largest demand for livestock manure is from farms that use it as fertilizer. Approximately 72% of livestock manure is used in farmland through composting and manure. However, as Korea’s farmland area has been continuously decreasing, the supply of livestock manure has increased while the demand has decreased. Livestock manure is not included in greenhouse gas emissions calculations due to carbon neutrality. It can also be used as an energy source. However, if not properly managed, it can cause environmental pollution. Therefore, it is necessary to calculate accurate air pollutant emissions through research on pollutants such as particulate matter caused by livestock manure combustion. This study utilizes the weight concentration method, which is a method of measuring particulate matter according to air pollution process test criteria. The purpose of this study is to analyze the concentration of fine particulate matter (PM-10) and ultra-fine particulate matter (PM-2.5) from combustion of livestock manure and develop emission factors. The PM-10 emission factor ranged from 2.48 g/kg to 7.72 g/kg, with an average value of 3.93 g/kg. The PM-2.5 emission factor ranged from 2.18 g/kg to 7.57 g/kg, with an average value of 3.62 g/kg. The correlation coefficients between the moisture content of cattle manure samples and PM-10 and PM-2.5 emission coefficients were 0.76 and 0.80, respectively; this indicates a strong positive correlation. As the moisture content of the manure sample increases, PM-10 and PM-2.5 emissions increase. This study described the particulate matter emission factors of manure burning processes for cattle manure, which is considered a potential alternative fuel. KCI Citation Count: 0
