1. A method of treating an organic waste containing hydrogen and carbon in molten metal contained in a vessel to sequentially form enriched hydrogen and carbon oxide gas streams comprising the steps of:

  • a) introducing the organic waste into molten metal, without the addition of a separate oxidizing agent and under conditions sufficient to decompose the organic waste and to form an enriched hydrogen gas stream and carbonize the molten metal;

    b) removing substantially all of the formed enriched hydrogen gas stream from the vessel;

    c) thereafter adding a separate oxidizing agent into the carbonized molten metal to oxidize carbon contained in the carbonized molten metal to form an enriched carbon oxide gas stream and to decarbonize the molten metal; and

    d) removing substantially all of the formed enriched carbon oxide gas stream from the vessel.
