Waste valorization strategies are key to achieve more sustainable production within the shrimp industry. The crustacean exoskeletons can be potentially used to obtain value-added products such as chitosan. A comprehensive analysis including both safety and sustainability aspects of chitosan production from shrimp shells is presented in this study. The inherent safety analysis and sustainability evaluation was performed using the Inherent Safety Index (ISI) methodology and the Sustainable Weighted Return on Investment Metric (SWROIM), respectively. The process was designed for a processing capacity of 57,000 t/year. The return on investment (%ROI), potential environmental impact (PEI output), exergy efficiency, and the total inherent safety index (ITI) were used as indicators to evaluate process sustainability. The total inherent safety index was estimated at 25 indicating that the process is inherently unsafe. The main process risks were given by handling of flammable substances, reactivity, and inventory subindices. The overall sustainability evaluation showed a SWROIM of 36.33% indicating that the case study showed higher weighted performance compared to the return on investment metric of 18.08%.

哥伦比亚虾外骨骼壳聚糖生产的固有安全性分析和可持续性评估

废物增值策略是在虾类行业实现更可持续生产的关键。甲壳类外骨骼可潜在地用于获得增值产品,例如壳聚糖。这项研究提出了包括虾壳壳聚糖生产的安全性和可持续性方面的综合分析。固有安全性分析和可持续性评估分别使用固有安全指数(ISI)方法和可持续加权投资回报率(SWROIM)进行。该工艺的设计处理能力为57,000吨/年。投资回报率(%ROI),潜在环境影响(PEI输出),火用效率和总固有安全指数(I TI)用作评估过程可持续性的指标。总的固有安全指数估计为25,表明该过程固有地不安全。主要过程风险是通过处理易燃物质,反应性和子索引来确定的。总体可持续性评估显示,SWROIM为36.33%,表明该案例研究与18.08%的投资回报率指标相比,具有更高的加权绩效。
