However, a major drawback of this technology is the production of hypersaline brine. This by-product contains salts and contaminants that have been removed during the desalination process, including antiscalants, cleaning agents, heavy metals, and organic compounds. Instead of disposing of this brine and causing environmental harm, new strategies should be developed to transform brine from a burden into an opportunity with environmental and economic benefits. Brine can harbor halotolerant and halophilic microorganisms, making it a valuable resource for studying microbial diversity, adaptations and exploring untapped biotechnological opportunities in pharmaceutical, industrial, and ecological fields. We propose two strategies of innovation: (i) using brine to cultivate micro- and macro-organisms, both of which can create circular economy models tailored to global and local needs. (ii) In addition, the amount of brine generated by desalination plants can be reduced by integrating or coupling them with biodesalination modules. These modules would harness halotolerant and halophilic organisms to retain and assimilate salts, reducing the environmental impact of desalination.
