Summary: This paper proposes a multi-objective optimization method for the layout design of chemical process plants, aiming to achieve a trade-off between economy and safety. The economic objective is evaluated by considering the total capital cost, while the safety objective is evaluated by the Comprehensive Inherent Safety Index (CISI). The proposed method is applied to optimize the layout of an acrylic acid production plant using the non-dominated sorting genetic algorithm II (NSGA-II). The results show a clear trade-off between economic and safety objectives according to the Pareto curve.

Summary: This review provides a comprehensive analysis of proactive risk reduction strategies (RRSs) and techniques for evaluating the performance of inherent safety, health, and environmental aspects. Background information is presented on the development and implementation of inherently safer process design and approaches for achieving inherently healthier and environmentally friendlier processes. The characteristics of inherency assessment tools (IATs) based on available information at different process stages are examined, and evaluation methods and historical development of IATs are investigated. The study concludes that there is a need for further research on no-chemical hazards-based IATs to improve the safety level of process plants.

Summary: This study developed a Reconciled Friendly Process Metric (RFPM) for generating Friendlier Chemical Processes (FCP) through Systematic Inherent Safety (SIS) modifications. By selecting and adapting prestigious inherent SHE and cost metrics to measure friendliness features, then reconciling them through Analytic Hierarchy Process (AHP) and Fuzzy Comprehensive Evaluation (FCE), the RFPM was validated through biodiesel production process. The results showed that the modified design was inherently friendlier than the base design, indicating the potential of RFPM as a tool for indicating the friendliness of processing scenarios and making trade-offs among safety, health, environmental, and cost concerns during design stage.

Summary: Ultrasonic waves, with a frequency greater than 20,000 Hz, have various applications in industry, medical field, and aesthetics. Recent studies have shown increased concern about the absorption of ultrasound by the human body, as people's exposure to these waves has significantly increased. Animal experiments have demonstrated organ damage from exposure to different ultrasonic frequencies. The main objective of this work was to compile and summarize recent studies on ultrasound to provide insight into its current state and establish a foundation for future research. It emphasizes the need for further research on the effects of ultrasound emissions on the human body to determine the potential impact on human health. The development of regulations by public administrations is necessary to ensure the safety and health of workers, healthcare professionals, patients, and the general public, in terms of occupational safety, indoor environmental quality, and environmental health.

Summary: This study evaluates and describes the indicators of occupational health, with a focus on medical expertise and periodic medical examinations. The results show that despite a decrease in absenteeism duration and a stable frequency of medical workers, the number of lost workdays per worker and the frequency of licenses increased. Additionally, worker adherence to periodic medical examinations showed a downward trend.

Summary: Food production has become more efficient but not necessarily sustainable. Transitioning to circular production systems can minimize waste and promote sustainability, but it can also result in the accumulation and recirculation of chemical hazards. It is important to identify and take preventive measures against these hazards in order to ensure food safety.

Summary: This study developed a synergetic and high-efficiency treatment of waste tantalum capacitors (WTCs) and polyvinyl chloride (PVC) using subcritical water process. The treatment significantly reduced the temperature and reaction time for metal tantalum recovery from WTCs, and improved the dechlorination efficiency of PVC. The optimized conditions resulted in 100% resin conversion efficiency of WTCs and 97.39% dechlorination efficiency of PVC. The interaction between decomposition products of WTCs and PVC produced a high level of benzoic acid.
