The escalating global population necessitates a paradigm shift toward circular bio-economies to mitigate the environmental burden of agro-industrial waste. Cauliflower (Brassica oleracea var. botrytis) processing generates immense quantities of non-edible biomass, with stems accounting for nearly one-third of the total plant weight. Traditionally discarded or utilized as low-value animal feed, these stems represent a potent source of bioactive compounds. This review systematically evaluates the transformation of cauliflower stems into a high-value functional powder (CSP). We detail its exceptional fiber profile (up to 31%), significant protein content, and the presence of health-promoting glucosinolates and polyphenols. Furthermore, we analyse its techno-functional role in enhancing food matrices—such as increasing water retention in meat analogues and mineral density in bakery products. By integrating CSP into the human food chain, the food industry can directly address Sustainable Development Goals (SDGs), specifically SDG 12 (Responsible Production) and SDG 3 (Good Health), effectively turning environmental waste into a nutritional goldmine.
