VENTED NICKEL CADMIUM

   These batteries are recycled in a pyrometallurgical process, whereby the shredded cells are blended with other nickel, chrome and iron bearing wastes and smelted in an electric arc furnace, to produce nickel alloy pigs, used as feedstock by specialty steel producers. The cadmium portion is converted to "pellets" in a retorting unit, for re-use, primarily in the battery industry.
