Current estimation of greenhouse gas(GHG) emissions form livestock agriculture in Korea was based on Revised 1996 IPCC Guidelines for National Greenhouse Gas Inventories (1996 IPCC GL) published in 1996 and emission data were published in National Inventory Report. New guideline book, 2006 IPCC Guidelines for the estimation of GHG emission would be necessary. Therefore 2006 IPCC GL for livestock manure made an analysis of CH₄ emission. Advanced Method Analysis was based on pig manure disposal form of "Biogas based power generation project at Jeongup-Si". In other words, Liquid and slurry system was Standardized Model. Calculated CH₄ emissions, and seemed to do the following. Annual CH₄ emissions was 0.0447 GgCH₄. Because of this, CO₂ emissions caused by livestock manure discharged for a total of 0.938 one thousand tCO₂e. Advanced Method is determined by the livestock and manure system. And Potential analysis of CH₄ Emissions has a higher reliability than the Simple Method. Data management of livestock species management system and data analysis are required for the future how to apply the Advanced Method. Because of this, CH₄ emissions can be managed according to the country"s livestock manure disposal. And The study is expected to be recognized for CH₄ emission reductions and expanded range of utilization.

Nitrous oxide (N2O), a greenhouse gas, influences global warming 295 times more than carbon dioxide does. N inputs applied to croplands including fertilizers and organic amendments are a major source of N2O emission. However, studies on N2O‐emanating organic amendments applied to croplands for improving soil fertility, especially livestock manure, are limited. Therefore, this study was conducted to measure N2O emission from sweet potato fields amended with livestock manure composts over a one‐year period. Three types of compost, cattle manure compost (CMC), swine manure compost (SMC), and poultry manure compost (PMC) were each added at rates of 10 and 20 Mg per hectare, and then the same amount of synthetic fertilizer was added to all treatments. N2O flux from fertilized soils was measured for one year, beginning in April 2018. The cumulative N2O flux from NPK, NPK+CMC 10 Mg ha‐1, NPK+SMC 10 Mg ha‐1, and NPK+PMC 10 Mg ha‐1 was 2.9, 5.5, 8.0, and 3.7 kg N2O‐N ha‐1 y‐1, respectively. The cumulative N2O flux from NPK+CMC 20 Mg ha‐1, NPK+SMC 20 Mg ha‐1, and NPK+PMC 20 Mg ha‐1 was 10.0, 14.7, and 5.8 kg N2O‐N ha‐1 y‐1, respectively. Soil treated with SMC emitted the largest quantities of N2O amongst the three composts. N2O emission factors from soils fertilized with CMC and SMC did not differ significantly from one another on the other hand, the emission factor from PMC was the lowest. A positive correlation was found between N2O emission and water‐filled pore space, with N2O emission drastically increasing at a WFPS >50%.

Livestock manure compost (LMC) can be used as an alternative nitrogen source instead of chemical fertilizer in order to reduce nitrous oxide (N₂O) emission. To evaluate the effect of LMC on reducing N₂O emission, we cultivated red pepper by treating with no treatment (Con), chemical fertilizer (CF), and the powder (LMCPD) and pellet type (LMCPE) of livestock manure compost for two years, and analyzed N₂O emission and plant growth. The N₂O emissions were 5.6 and 5.5 kg N₂O ha<SUP>-1</SUP> for the LMCPD and LMCPE treatments, respectively, which were lower by 48% than that of the CF treatment, 11.6 kg N₂O ha<SUP>-1</SUP>. The yields of red pepper fruits of LMC treatments were 70.8 - 94.7% of that of CF treatment, but the yields were not significantly (p > 0.05) different between CF and LMC treatments. The lower yields of LMC treatment were attributable to deficiency of some other nutrients such as potassium (K) rather than nitrogen. Those results suggested that LMC can contribute more positively to reducing N₂O emission than to reducing red pepper yield.

Improving sustainability of peat moss through its application in reducing livestock emissions

Nugrahaeningtyas, Eska,Park, Kyu-Hyun 한국기후변화학회 2024 한국기후변화학회지 Vol.15 No.2

Peat, also known as peat moss, is comprised of decomposed plants. Peatland ecosystems act as natural carbon sinks and carbon storage systems and support biodiversity. Owing to its beneficial properties, peat moss has been widely used in the horticultural and agricultural industries as a substrate and in the waste management industry as an absorbent. However, its harvest from peatland releases anthropogenic greenhouse gas (GHG) emissions. Thus, using peat moss to reduce GHG emissions from other sectors could compensate for the emissions from peat moss harvesting. Livestock practices emit GHGs, including methane (CH₄) and nitrous oxide (N₂O), and release non GHG emissions such as ammonia (NH₃). Though peat moss has been used as bedding material in animal pens, its effect on reducing emissions from livestock practices remains unknown. This paper reviews the potential of peat moss in livestock manure management to reduce CH₄, N₂O, and NH₃ emissions, presenting alternatives for sustainable use of peat moss. Manure treatments using materials with similar attributes to peatmoss, e.g., acidification treatment, showed that CH₄, N₂O, and NH₃ emissions were effectively reduced. Further, the use of peatmoss as bulking materials in manure enhanced the sorption of NH₃. Hence, peatmoss application in manure may potentially reduce CH₄, N₂O, and NH₃ emissions. Moreover, the benefit of peatmoss application is not only limited to reduction of emissions, but it may also improve soil health when peatmoss-treated manure is applied to soil due to its high carbon content. Therefore, peatmoss application in the livestock industry should be further explored.

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 40~55°C 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 93~99%. Among them, CH3SH, which accounts for about 56~89% 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 0.5~0.8% 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.

가축분뇨 연소과정의 미세먼지 배출계수 개발 - 우분을 중심으로 -

유재호,전의찬 한국기후변화학회 2020 한국기후변화학회지 Vol.11 No.5

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.

축사 악취 특성 및 관리 (II) : 악취 배출 특성

조경숙,류희욱 한국냄새환경학회 2023 실내환경 및 냄새 학회지 Vol.22 No.1

In this review paper, the sources of odor, major odor compounds, and emission characteristics from livestock farms are summarized. The main sources of odor on livestock farms are barn facilities, manure storage facilities, manure composting facilities, and wastewater treatment facilities. High concentrations of odor are emitted during the manure removal process, and livestock odor tends to be the most severe in summer. There was a remarkable difference in odor intensity depending on the farm size and the cleaning condition, and odor intensity varied greatly depending on the weather parameters such as wind direction and speed. The concentrations of ammonia and hydrogen sulfide were high among the odor compounds emitted from livestock farms, and these compounds also contributed to odor intensity. The odor intensity in poultry and swine farms was higher than in cattle farms. Information on livestock odor emission is very useful for managing livestock odor complaints and designing odor abatement technologies.

The purpose of this study is to improve the ammonia (NH3) emission inventory estimation in the domestic CAPSS(Clean Air Policy Support System). Currently, the ammonia emissions rate is obtained by multiplying the activity(number of livestock) by emission factors. The amount of movement and treatment are not considered in theestimation of ammonia emission rates. However, livestock manure is currently moved and treated in accordancewith the energy recycling policy. In this study, the new emission estimation method were suggested consideringthe moving and treatment characteristics of livestock manure. A new ammonia emissions was calculated for Bcityand Y-gun at Chungcheongnam-do province. It was shown that the moving and treatment ratio of ammoniaemissions were 4.3% and 8.4%, respectively. Furthermore, this ratio would be increased rapidly with the continuousestablishment of large-scale manure treatment facilities.

In this study, researches on the development of country specific greenhouse gas measurement and sampling methods from the livestock sector were reviewed. Research on greenhouse gas emission factors was started in early 2000 but was not actively involved in the development of livestock sector based emission factor: since 2009, works are underway for the development of livestock sector based emission factor. Most of the research on greenhouse gas emission in the field of animal studies were done by National Institute of Animal Science, because of the uniqueness of the research laboratories. Methods of emission measurement are still not internationally certified and therefore, measurement and sampling methods for Korea livestock sector are being studied, consulting the worldwide research trends. Flux chamber method are commonly using in Korea for green house gas emission factors measurement. In recent years, continuous measurement of the microclimate was introduced to measure greenhouse gases from livestock manure storage facilities and the micrometeorology method should be adapted as recommended by Intergovernmental Penal on Climate Change (IPCC) Guideline.
