“…It can also be difficult to access this data for industrial processes where it is often kept confidential. However, it is possible to use a simplified approach to assess eco-efficiency that uses environmental impact indicators instead of environmental impact scores determined by an LCA [ 39 , 40 , 41 ] ( Table 1 ). These indicators, determined by an analysis of the process, are linked to inputs or outputs contributing significantly to the environmental impact (e.g., energy consumption, water consumption, etc.).…”

“…Different parameters can be selected to influence the selectivity and thus recover specific compounds: the pH of the feed, electrical field strength, conductivity, membrane physicochemical characteristics, the MWCO of the membrane, the mode of current, etc.) [ 11 , 39 , 75 , 76 , 77 , 78 , 79 , 80 ]. Applications in several fields have been demonstrated, such as the separation of bioactive peptide fractions [ 77 , 78 , 79 ], the improvement of protein hydrolysate bioactivity [ 80 ], the selective recovery of monovalent ions [ 81 ], the separation of antibiotics from wastewater [ 82 ], the simultaneous hydrolysis and separation of peptides [ 83 , 84 ], and also the separation or concentration of protein [ 85 ], chitosan oligomers [ 86 ], and phenolic compounds [ 87 ].…”

“…This study is part of the numerous works on the pertinence of EDUF to give a second life to valuable compounds. Moreover, this process was tested very recently and for the first time at a semi-industrial scale [ 39 , 40 , 145 ]. The potential to valorize β-lactoglobulin was also investigated deeper with the demonstration of an electrodialytic reactor, based on an EDUF configuration, for the enzymatic hydrolysis of the protein and the simultaneous fractionation of generated bioactive peptides in one step.…”

“…Hence, in the context of the industrial application of this technology, two EDUF configurations were compared at a semi-industrial scale-up and adapted to reach the most efficient and selective process. Indeed, CEM/UF/CEM and CEM/UF/AEM configurations of EDUF were tested [ 39 ]. They allowed the recovery of 10 predominantly cationic peptides from a tryptic whey protein hydrolysate.…”

Wastewater and by-product treatments are substantial issues with consequences for our society, both in terms of environmental impacts and economic losses. With an overall global objective of sustainable development, it is essential to offer eco-efficient and circular solutions. Indeed, one of the major solutions to limit the use of new raw materials and the production of wastes is the transition toward a circular economy. Industries must find ways to close their production loops. Electrodialysis (ED) processes such as conventional ED, selective ED, ED with bipolar membranes, and ED with filtration membranes are processes that have demonstrated, in the past decades and recently, their potential and eco-efficiency. This review presents the most recent valorization opportunities among different industrial sectors (water, food, mining, chemistry, etc.) to manage waste or by-product resources through electrodialysis processes and to improve global industrial sustainability by moving toward circular processes. The limitations of existing studies are raised, especially concerning eco-efficiency. Indeed, electrodialysis processes can be optimized to decrease energy consumption and costs, and to increase efficiency; however, eco-efficiency scores should be determined to compare electrodialysis with conventional processes and support their advantages. The review shows the high potential of the different types of electrodialysis processes to treat wastewaters and liquid by-products in order to add value or to generate new raw materials. It also highlights the strong interest in using eco-efficient processes within a circular economy. The ideal scenario for sustainable development would be to make a transition toward an eco-circular economy.
