Marine Macrophytes as Macromolecular Resources in the Mediterranean Circular Bioeconomy: Ecology, Green Ex-Traction, Bioactivity, and Valorization of Posidonia oceanica, Padina pavonica, and Chaetomorpha linum
Marine macrophytes are major components of Mediterranean coastal ecosystems and potential sources of renewable macromolecules, functional extracts, and structural materials. This review critically compares three taxonomically and chemically distinct biomasses: the endemic seagrass Posidonia oceanica, the calcified brow...
