|a This study investigates the development of bone hydrochar via hydrothermal carbonization (HTC) and its potential for arsenic removal, with a comparative sustainability assessment against biochar and bone char. Bone hydrochar was synthesized at 180 °C using a 1:10 water-to-bone meal ratio for 1 and 2 h. Characterization revealed a decrease in CO32- content from 15 % to 8 % with increased HTC duration. The arsenic sorption capacity of bone hydrochar reached 3.5 mg∙g-1, surpassing that of torrefied and pyrolyzed bone char but remaining lower than engineered biochar. Artificial neural network (ANN) modeling highlighted the importance of applying Leave-One-Out Cross-Validation (LOOCV) to ensure robust evaluation and minimize overfitting risks under limited-data conditions. Life cycle assessment (LCA) indicated that hydrochar production exhibited a higher global warming potential (GWP) than biochar, with values of 9.93 kg CO2 eq for rice husk hydrochar and 9.85 kg CO2 eq for bone hydrochar, compared to 0.696 kg CO2 eq for rice biochar and 0.679 kg CO2 eq for bone char. Bone meal production emits only 0.027 kg CO2 eq, while rice husk production generates significantly higher emissions, at 0.107 kg CO2 eq. Conventional torrefaction consumes 0.75-0.83 kWh of energy, while hydrochar production requires significantly more energy, at 9.7 kWh. These findings highlight the trade-offs between arsenic sorption efficiency and environmental sustainability, informing the optimal selection of biochar and hydrochar for water treatment applications
