In this study, cattle and pig slaughterhouse wastes (SHWs) were hydrothermally carbonized at 150–300 °C, the properties of SHW-derived hydrochar evaluated for its use as a solid fuel. The results demonstrated that increasing hydrothermal carbonization (HTC) treatment temperature improved energy-related (i.e., fuel ratio, higher heating value, coalification degree) both hydrochars. However, impr...

Spent coffee grounds (SCG) are industrial biowaste resulting from the coffee-brewing process, and they often underutilized end up in landfills, thereby leading to emission of toxic gases environmental damage. Hydrothermal carbonization (HTC) is an attractive approach valorize wet biomass such as SCG valuable bioproducts (i.e., hydrochar). Thus, this work, HTC was carried out a 500 L stainless s...
