Conversion of Slaughterhouse Wastes to Solid Fuel Using Hydrothermal Carbonization

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, improvements hydrochars not dramatic hydrochars, due to lipid-rich components do participate in HTC reaction. regard, there was no merit using on SHW production or terms energy retention efficiency. On other hand, mild approximately 200 °C deemed suitable converting value-added findings study suggest conversion SHWs can provide an environmentally benign method waste recovery from abandoned biomass. efficiency varies depending chemical composition raw feedstock.
