PURPOSE:To economically and efficiently dispose all waste produced in a ship, by a method wherein the waste is heated by a heat exchanger, concentrated bilge water is fed in a sprayed condition into a second incinerator, and a vacuum generator, being capable of reducing the pressure of a gas phase part in a tank, is connected to the tank. CONSTITUTION:With a vacuum generator 5 actuated, the gas phase part of an upper space 1' is reduced in a pressure to promote vaporization of a moisture content in bilge, and along with a heating action of bilge with the aid of a heat pipe 2, efficient concentration of bilge is effected. The concentrated bilge, increased in content of oil, is stowed in a tank 4t. Meanwhile, after waste oil produced in a ship is stowed in a tank 8t, the waste oil is emulsified to feed it to a first incinerator 6. The waste oil is sprayed by an atomizer 16 for combustion. Solid combustible substance, such as solid waste, garbage, is adjusted into proper size, and is charged in the incinerator 6 for combustion. The concentrated bilge is sprayed by the atomizer 9, heat is imparted on the bilge within a second incinerator 7 under a high temperature condition, and the bilge is increased in temperature for evaporation and is burnt.
