WASTE TREATMENT METHOD

The invention relates to a waste treatment furnace and method. The method consists of the following steps: a molten metal bed is generated, which moves in a forward direction such as to define a closed circuit in a cyclical and continuous manner, the surface of said bed including at least one essentially-slag-free segment; waste is loaded onto the aforementioned essentially-slag-free segment and said waste is dragged by the molten metal bed such that it floats in the forward direction; the waste is retained on the surface of the molten metal bed as it moves forward; and the waste is treated under the effect of the constant and continuous heat exchange generated by the movement of the molten metal bed beneath the waste retained thereon.
