|a In this study, hydrochars were prepared at varying temperatures with distinct mixing ratio, and then the hydrochars were characterized and evaluated for heavy metals to ascertain its potential as a soil conditioner. The application of elevated temperatures resulted in a reduction in the yield of hydrochars, whereas the incorporation of coffee grounds led to an increase in the yield. The blended hydrochar displays elevated ash, fixed carbon, and diminished H/C, O/C, and (O + N)/C ratios, indicating enhanced stability in soil treatment and potential for enhanced soil fertility. The application of hydrothermal carbonization facilitated the stabilization of heavy metals within the sewage sludge, with the stabilizing effect being enhanced by the addition of coffee grounds. Following the application of SCC as a soil conditioner to the heavy metal-contaminated soil for a period of 90 days, it was observed that the heavy metals Cu, Cr, and Ni present in the contaminated soil underwent a transition from an unstable to a stable speciation. Of the treatments tested, AK15 was identified as the most effective, demonstrating a significant reduction in the risk of leaching and biotoxicity associated with Cu, Cr, and Ni in the contaminated soil
