moisture content solid wastes into dried usable product using low energy consumption. It can
treat wide range application from waste food to sewage sludge and has wide range product from
solid fuel to liquid fertilizer8.
It can be seen from Figure 1 that the operating condition of Tokyo Tech process differs from
other processes such as sub-critical water oxidation and waste autoclave. Not only is the aspect
of temperature different but also the water phase (it uses the saturated phase) Therefore, the
operating pressure is not high compared to ordinary water-phase hydrothermal treatment, and it
will be economical to build the plant, such as shown in Figure 2 below
