The brine was a cost center \u2014 an environmental liability requiring expensive diffuser systems to minimize ecological damage. No board of directors saw brine as anything other than a problem to manage.<\/p>\n<p>That paradigm is shifting rapidly. In <strong>June 2026<\/strong>, the <strong>World Economic Forum<\/strong> identified brine valorization \u2014 the extraction of commercially valuable minerals from desalination concentrate \u2014 as one of five water-security technologies reshaping global industry.
