In this study, an iron\u2010carbon composite was produced from digestate through polyethylene glycol (PEG)\u2010assisted iron modification followed by low\u2010temperature carbonization. The resulting material exhibited a mesoporous texture, oxygen\u2010containing surface functionalities, and Fe\n                    <jats:sub>3<\/jats:sub>\n                    O\n                    <jats:sub>4<\/jats:sub>\n                    \/Fe\n                    <jats:sub>3<\/jats:sub>\n                    C domains, enabling efficient removal of Congo red in batch systems. Removal was favored under mildly acidic conditions. At pH\u20094 and 298\u2009K, the maximum experimentally observed equilibrium uptake reached 1267.35\u2009mg\u00b7g\n                    <jats:sup>\u22121<\/jats:sup>\n                    at high initial concentration, and removal efficiencies approached 99% under the tested conditions. The adsorbent retained more than 95% of its initial removal performance after five regeneration cycles. Kinetic and equilibrium analyses, together with FTIR\/XPS and post\u2010adsorption characterization, support that uptake involves Fe\u2010associated interactions, electrostatic effects, and hydrogen bonding, with additional high\u2010coverage accumulation contributing at elevated concentrations. Overall, this work demonstrates a practical route to valorize anaerobic digestate into a reusable adsorbent for removing azo dyes from wastewater.\n
