Abstract
Purpose: This study aims to investigate the potential of recycling spent coffee grounds (SCG) as an auxiliary biofuel to improve energy efficiency and odor reduction in low-temperature sludge drying systems. Research Design & Data Collection: A pilot-scale closed-loop belt dryer equipped with an inverter-driven scroll compressor (30–200 Hz) was tested under varying compressor frequencies (130, 160, 180 Hz). Experimental data were collected for power use, temperature, pressure, and moisture content. Pilot-scale validation was supported by certified industrial testing (KTI and Daejeon Analytical Research Institute, 2025), confirming a mean SEC of 0.579 kWh kg⁻¹-H₂O and a final moisture of 7.4 wt %, both within design targets. Research Results: The system achieved an average Specific Energy Consumption (SEC) of 0.607 kWh/kg-H₂O and reduced final moisture content to 4.6 wt%, outperforming target thresholds of 0.64 kWh/kg-H₂O and 10 wt%. Operators also reported a noticeable reduction in odor emissions, suggesting SCG's adsorption capacity, though quantitative odor profiling remains a subject of future study. Conclusion: The findings confirm that SCG can serve as an effective auxiliary fuel, enhancing both energy efficiency and environmental performance. The developed system presents a scalable solution for sustainable sludge management within the framework of circular economy principles
Abstract
Purpose: In this study, pollutants generated in industrial areas were measured using a Portable Air Quality Measurement System(PAQMS). This study intends to examine in detail improvement measures and operational capabilities to operate a more efficient PAQMS. Research design, data and methodology: This study compares and analyzes the measurement values of the PAQMS and the measurement values of the national air quality measurement network. It is intended to develop a PAQMS corresponding to the data of the national measurement network by minimizing the errors that occur during comparative measurement and analysis and supplementing and improving the problems that occur during the current equipment calibration. Results: A PAQMS is an essential equipment for faster and more accurate measurement and analysis of pollutants in case of untimely measurement and civil complaints due to Micro Climate(local weather and environmental influences). Currently, there are many atmospheric measurement equipment in Korea, but only equipment for each item is produced and sold. Currently, these devices on the market must satisfy various conditions such as stable power, temperature, and humidity to calculate accurate measurement values. Conclusions: Therefore, there is no equipment that satisfies the conditions for performing detailed measurement in the field where accurate measurement is required. In this study, these field work conditions and contents for stable measurement were mentioned in the text.

Abstract
Purpose : This study investigates the biochemical mechanisms and removal strategies for aging odor (2-Nonenal) and indoor air odor (VOCs, H2S, NH3). Both odor types share volatile aldehydes as key contributors, making them persistent and challenging to eliminate with conventional deodorization methods. While aging odor originates from lipid peroxidation in sebaceous glands, indoor air odor is primarily caused by microbial metabolism and environmental pollutants. This study aims to develop a bio-based odor removal strategy integrating plant-based antioxidants, marine bio-adsorbents, and microbial degradation technologies for long-term odor control. Research Design & Data : A qualitative, literature-based research approach was employed, incorporating a systematic review of peer-reviewed journals, patents, and industrial reports. The study utilizes comparative analysis to evaluate the persistence, chemical structure, and removal techniques of aging and indoor air odor. Bio-based solutions are explored, including polyphenol-rich plant extracts, fucoidan-based marine bio-adsorbents, and enzymatic microbial filtration systems. Research Results : The findings reveal that conventional deodorization methods, such as chemical masking agents and activated carbon filters, provide only temporary relief and fail to address the underlying biochemical reactions leading to odor formation. In contrast, bio-based solutions offer sustainable, long-term odor management, effectively neutralizing both aging odor and indoor air pollutants. Conclusion : By integrating plant antioxidants, marine bio-adsorbents, and microbial enzymatic degradation, this study proposes a holistic, eco-friendly odor removal system applicable to personal hygiene, indoor air quality, and elderly care environments. Future research should focus on experimental validation and real-world application testing to optimize and commercialize bio-based deodorization technologies
Abstract
Purpose: The purpose of this study is to reduce odor complaints by identifying problems with odor management at the site of the water regeneration center and researching odor management methods. Due to the high population density of Korea, sewage treatment facilities are adjacent to residential and industrial areas. According to previous studies, the main malodor-emitting facilities of sewage treatment facilities were preliminary treatment facilities (2,220 times), sedimentation basins (4,628 times), and sludge treatment facilities (9,616 times). Research design, data and methodology: Compound malodors and designated malodor-producing substances were collected from five site boundaries of the water regeneration center and analyzed according to the official methods to test malodor, and a total of two times (August and September 2020) were conducted. Results: As a result of the measurement, in the green area in front of the center office, compound malodors were detected at a maximum of 8 times and at least 3 times during the dawn time. As for the designated malodor-producing substances, 0.1ppm of ammonia was detected in the green area in front of the center office and the park golf course. This is within 15 times the maximum allowable emission level of compound malodors and within 1ppm of the maximum allowable emission level of ammonia. Conclusions: Even if the dilution rate of the compound malodors did not exceed the maximum allowable emission level, the odor could be recognized, and more research is needed in the future to establish effective reduction measures according to the subjective and individual and seasonal odor characteristics.
