In this study, actual odor conditions were investigated in restaurants, livestock facilities, and major odor discharge facilities around daily life, and an odor modeling program was performed to find ways to improve odors in odor discharge facilities. The odor modeling results of restaurants around daily life showed that the complex odor concentration of large restaurants, which are close to residential areas, is higher than the acceptable complex odor standard at the receiving point. It was judged that a plan to increase the height of the restaurant odor outlets and a plan to reduce the amount of odor discharge was necessary. As a result of modeling the life odor of livestock housing facilities, when the distance from the housing facility is far away, the actual emission concentration is much lower than the acceptable emission concentration at the receiving point. It was judged that such facilities need to be reviewed for ways to reduce the emission of odorous substances, such as sealing the livestock housing facilities or improving the livestock environment. The main odor emission business sites that show complex odor concentration as 1,000 times or greater than the outlet odor emission standard were businesses associated with surfactant preparation, compounded feed manufacturing, textile dyeing processing, and waste disposal. Due to the separation distance and high exhaust gas flow rate, it was found that odor reduction measures are necessary. In this study, it was possible to present the allowable odor emission concentration at the discharge facilities such as restaurants, livestock houses, and industrial emission facilities by performing the process of verifying the discharge concentration of the actual discharge facility and the result of living odor modeling. It is believed that suitable odor management and prevention facilities can be operated.

In this study, real-time monitoring of air quality using a real-time mobile monitoring system was conducted to identify the emission characteristics and current status of air pollutants and odorous substances that are mainly generated in domestic dyeing industrial areas and to trace the pollutant sources. The concentration of toluene in the industrial area was detected up to 926.4 ppb, which was 3 to 4 times higher than that of other industrial areas. The concentration of methylethylketone was 124.7 ppb and the concentration of dichloromethane was 129.5 ppb. Acrolein concentration was highest at E point at 521.6 ppb, methanol concentration was highest at D point at 208.8 ppb, and acetone concentration was highest at M and N points at 549.3 ppb. The most frequently detected concentration of pollutants in the air quality monitoring results in the industrial area was, in descending order, toluene > methanol > acrolein > dichloromethane > acetone, which was similar to the chemical emissions used in the industrial area by the Pollutant Release and Transfer Register data. The concentration of odorous substances measured in real time was compared with the concentration of minimum detection, and the concentration of hydrogen sulfide was about 10 times higher than the concentration of minimum detection at A point, which was judged to be the main odorous cause of A point. In the future, if the real-time mobile measurement system is constructed to automatically connect wind direction/wind speed, PRTR (Pollutant Release and Transfer Register) data and SEMS (Stack Emission Management System) data, etc., it was judged that more accurate monitoring could be performed.

바이오디젤은 석유기반의 디젤을 대체할 수 있는 유망한 대체에너지원으로 각광받고 있으나 그 생산 공정의 경제성을 확보하는 것이 관건이다. 따라서 사회성, 경제성, 환경성을 동시에 고려할 수 있는 값싼 원료를 찾는 다면 지속가능성 측면에서 매우 유용할 것이다. 이에 따라 본 연구는 다양한 육류(소, 돼지, 오리)를 이용하여 판매하는 음식점에서 버려지는 폐지방을 대상으로 전이에스테르화 반응을 수행하여 바이오디젤을 생산하였으며 fatty acids methy ester (FAME)을 추출하여 그 구성특성을 규명하였다. J시 음식점 중 소, 돼지, 오리를 찌거나 훈제하는 음식점으로부터 발생된 폐지방을 수집하여 KOH와 메탄올을 이용한 전이에스테르화 반응을 통해 바이오디젤을 생산하였고, 간단한 n-hexane을 통해 FAME만을 추출한 뒤 GC-FID를 이용하여 정량하여 그 구성특성을 분석하였다. 실험결과에서 FAME의 프로파일 분석결과는 폐지방성분이 유용한 바이오디젤원료가 될 수 있는 것으로 나타났다. 37도에서 한 시간 동안의 전이에스테르화에 있어 KOH는 폐지방을 FAME으로 우수한 효율로 전환가능하게 하는 촉매로 판단된다. 소, 돼지, 오리의 폐지방에 대하여 각각 48%, 45%, 55%의 질량이 총 FAME으로 전환되는 것으로 나타났다. 총 지방의 2%이상의 질량비율을 갖는 주요 FAME은 소의 경우 C16:0 (13.1%), C18:1 (22.4%), C18:0 (8.6%) 이었고, 돼지의 경우 C16:0 (12.3%), C18:1 (26.5%), C18:2(8.0%), C18:0 (5.3%)이었으며, 오리는 C16:0 (9.4%), C18:1 (23.0%), C18:2 (7.2%), C18:2 (2.7%)로 나타났다. 이러한 높은 FAME 수율과 C16:0과 C18:1 의 우점화는 일반적인 바이오디젤의 특성과 유사한 것으로 살료된다. 종합하면, 본 연구결과는 동물성폐지방 성분의 바이오디젤화의 가능성을 열어주며 최적반응조건 도출을 통해 실현가능한 대체에너지생산 및 페자원 에너지화 방법임을 보였다.
