The high freshwater consumption requirements in shrimp biorefinery approaches represents one of the major drawbacks of implementing these technologies within the shrimp processing industry. This also affects the costs associated with the plant operation, and consequently, the overall economic performance of the project. The application of mass integration tools such as water pinch analysis can reduce frewshwater consumption by up to 80%, contributing to shrimp biorefinery sustainability. In this work, the economic evaluation and the techno-economic sensitivity analysis for a mass integrated approach for shrimp biorefinery were performed to determine the economic feasibility of the project when located in the North-Colombia region and to identify the critical techno-economic variables affecting the profitability of the process. The integrated approach designed to process 4113.09 tons of fresh shrimp in Colombia reaches a return on investment (%ROI) at 65.88% and a net present value (NPV) at 10.40 MM USD. The process supports decreases of up to 28% in capacity of production and increases of 12% and 11% in the cost of raw materials and variable operating costs without incurring losses, respectively. These findings suggest that the proposed design of the water recycling network coupled to a shrimp biorefinery approach is attractive from an economic point of view.
虾类生物精炼方法中对淡水的高消耗需求是在虾类加工业中实施这些技术的主要缺点之一。这也会影响与工厂运营相关的成本，进而影响项目的整体经济绩效。诸如水夹点分析等质量集成工具的应用可将淡水消耗量降低多达80%，有助于虾类生物精炼的可持续性。在这项工作中，对虾类生物精炼的质量集成方法进行了经济评估和技术经济敏感性分析，以确定该项目位于哥伦比亚北部地区时的经济可行性，并确定影响该工艺盈利能力的关键技术经济变量。在哥伦比亚设计的用于加工4113.09吨鲜虾的集成方法的投资回报率（%ROI）达到65.88%，净现值（NPV）为1040万美元。该工艺支持产量降低多达28%，同时原材料成本和可变运营成本分别增加12%和11%，且不会产生亏损。这些发现表明，从经济角度来看，所提出的与虾类生物精炼方法相结合的水循环网络设计具有吸引力。
