Hydrothermal carbonization (HTC) is a novel thermochemical process that turns biomass into hydrochar, substance rich in carbon has potential uses advanced material synthesis, energy production, and environmental remediation. With an emphasis on important chemical pathways, such as dehydration, decarboxylation, polymerization, control the conversion of lignocellulosic useful this review critically investigates fundamental chemistry HTC. A detailed analysis conducted effects variables physicochemical characteristics including temperature, pressure, composition, water ratio, residence time. Particular focus placed new developments HTC technology improve sustainability efficiency, like recirculating microwave-assisted co-hydrothermal carbonization. Furthermore, improvement adsorption capacity for organic contaminants heavy metals explored relation to functionalization activation namely through surface modification KOH treatment. The performance hydrochar biochar adsorption, catalysis, storage compared, emphasizing unique benefits difficulties each substance. Although comparatively high higher heating value (HHV) can be good substitute coal, issues with reactor design, scalability, secondary waste management continue limit its widespread use. In order maximize sustainable profitable avenue valorization, study addresses critical research gaps future initiatives.

Abstract The application of hydrochar as a cost-effective solution has received much attention for the remediation contaminated water. An economical and environmental approach to enhancing physicochemical adsorption performance is essential. In this study, green technology ball-milling was firstly employed improve capacity typical antibiotics norfloxacin. Aqueous batch experiment using both pristine ball milled derived from water hyacinth, prepared by hydrothermal carbonization at three temperatures (180, 200, 220 °C) conducted. results showed that decreased specific surface area hydrochar, but still greatly enhanced their on Surface functional groups, aromatization degree, hydrophobicity were increased after ball-milling, evidenced measurements Boehm titration, Raman spectra, contact angle, respectively. With these changes, all ball-milled hyacinth exhibited better norfloxacin than hydrochar. Ball-milled °C greatest (68.53 mg g −1 ) compared unmilled (24.29 ), enhancement effective in wide pH range (5–9) aqueous solutions. thermodynamics study indicated physically spontaneous exothermic. Combined characterization suggest owing boosting H-bonds, π-π electron-donor–acceptor, hydrophobic interaction. This suggested can be served facile, green, method obtain modified removal pollutants
