Abstract
<jats:p>Pollution associated with armed conflicts poses a complex threat to marine environments, including heavy metals, hydrocarbons, persistent organic pollutants, plastic debris, and contaminated sediments. In this context, the article analyses the potential of geopolymer technology as a sustainable solution for remediating contaminants generated by military and industrial activities, with a focus on the conservation of marine ecosystems. Geopolymers, due to their aluminosilicate structure, controllable porosity, and capacity for adsorption, ion exchange, and encapsulation, can contribute to the retention and immobilization of hazardous pollutants. The paper highlights the main mechanisms through which geopolymeric materials can reduce the mobility of contaminants and limit their impact on biodiversity and water quality. The proposed approach supports the development of integrated decontamination and conservation solutions, in line with the current need to protect the marine environment affected by civil and military pollution.</jats:p>
