Abstract(s)

The production of hydrochars from compost through hydrothermal carbonization (HTC) was studied as valorization alternative against organic waste accumulation. Temperature, time and load of compost were varied in the HTC process and the carbon content of the solid and the liquid effluent were used as dataset to develop a kinetic model able to predict the carbon content in the hydrochars and in the effluent at different operating conditions. Furthermore, the treatment of the liquid effluent resulting from the HTC process was assessed by Fenton reaction.
