Chicken manure (CM) is a nutrient-rich but environmentally problematic biomass that requires sustainable management. This study applied three-step process consisting of hydrothermal activation (ZnCl2 or H3PO4), catalytic carbonization (HCl FeCl3), and low-temperature pyrolysis (250 °C) to develop an energy-efficient method for producing biochar. The resulting biochars were systematically analyzed their physicochemical properties, heavy metal content, carbon sequestration potential, compared with conventional pyrolysis-based biochars. Among the tested samples, biochar produced via H3PO4 HCl-catalyzed HTC [P-HTC(HCl)] exhibited most favorable characteristics, including highest content (59.5 wt.%) lowest H/C ratio (0.65). As result, it achieved total potential (TPC, 158.8 gcarbon/kgbiochar) CO2 reduction (CRP, 465.9 gCO2-eq/kgbiochar), attributed strong dehydration decarboxylation reactions effective inorganic removal induced by Brønsted acid action. In contrast, showed significantly higher concentrations metals—up 633 mg/kg Cu 2331 Zn—due thermal concentration effects, whereas P-HTC(HCl) presented more balanced acceptable profile. conclusion, proposed hydrothermal-assisted demonstrates great high-performance from chicken enhanced environmental safety storage efficiency.
