“…This stage is required to avoid the hydrolysis of chitin in further processing [ 28 ]. The main stream feeds into an interstage neutralization process using 1 M sodium hydroxide solution and further washing [ 29 ]. The resulting wastewater containing NaOH is mixed with the freshwater stream and sent back for neutralization and washing according to the proposed water recycling network.…”

“…A nitrogenous extract results from this stage as a by-product with potential applications as fertilizer. The chitin-rich stream leaving the deproteination stage is neutralized using HCl solution at 1.5 M and washed thoroughly [ 29 ]. The wastewater from the chitin washing stage is also recycled to the previous interstage neutralization and washing (water recycling network) process.…”

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.

“…The criteria considered to evaluate the sustainability of the process are economic, environmental, energy, and safety. The information required to perform the safety analysis and the technical indicators (%ROI, PEI output, and exergy efficiency) for the sustainability evaluation were obtained from process simulation, techno-economic evaluation [14], environmental analysis, and exergy analysis [13] previously developed by the authors. The general methodology applied in this work is depicted in Figure 1.…”

“…The return on investment percentage (%ROI) of 18.08% reveals that the process is economically attractive. Next, the potential environmental impact output and generated by the process were evaluated [13]; the key data and assumptions used in the environmental assessment include the use of oil as a fuel and the evaluation of energy and product stream contributions. The results are presented in figures 6 and 7.…”

“…Therefore, several works have been addressed to evaluate the economic, energetic, and environmental aspects of this process on a large scale. Meramo-Hurtado et al [13] simulated a plant for chitosan production from shrimp exoskeleton in Colombia and carried out the environmental analysis and the exergy analysis, while Cogollo-Herrera et al [14] performed the techno-economic evaluation of this same process.…”

The recovery and valorization of waste are some of the key aspects of sustainable production. 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/y according to shrimp production in Colombia. The economic (%ROI), environmental (PEI output), energy (exergy efficiency), and safety (ITI) technical parameters were included in the sustainability evaluation. The three first were obtained from the previous analysis performed by the authors. The total inherent safety index was estimated at 25 indicating that the process is inherently unsafe. The main process risks were given by the dangerous substance, reactivity, and inventory subindices. The overall sustainability evaluation showed a SWROIM of 36.23% indicating that the case study showed higher weighted performance compared to the return on investment (ROI) metric of 18.08%.
