Hydrothermal treatment is a technology to produce dried, uniform solid fuel or organic fertilizer by
converting unutilized bio-resources such as food residues, sewage sludges, animal manures,
agricultural residues, high moisture content solid wastes and MSW using low energy
consumption [16]. The process began by loading the raw MSW and injecting saturated steam of about
200 °C and 2 MPa for a certain period into the stirred hydrothermal treatment reactor. After finishing
the reaction and discharging the steam, a wet, uniformly-crushed material was extracted from
the reactor.
