1. A method for controlling chemical reaction of a waste, comprising the steps of:

  • a) directing the waste into a reactor within which a molten metal bath is disposed, the molten metal bath causing chemical reaction of at least a portion of the waste, whereby an intermediate component and atomic constituents are formed, a portion of the intermediate component combining with an off-gas formed in the reactor and being emitted from the reactor;

    b) separating at least a portion of the intermediate component from the off-gas to form an intermediate stream;

    c) directing said intermediate stream into the reactor for chemical reaction of the intermediate component which is returned to the reactor to form atomic constituents and subsequent exothermic reaction of at least a portion of the atomic constituents with an oxidant in the molten metal bath; and

    d) directing an oxidant into the molten metal bath which exothermally reacts with said atomic constituents, whereby heat generated by the exothermic reaction initiates additional chemical reaction of the waste and of the intermediate component, thereby controlling chemical reaction of the waste.
