A waste treatment system processes waste upon the application of energy. The system includes a vessel that contains an open space. A waste feed system feeds inorganic and/or organic waste into the open space of the vessel. One or more pairs of electrodes are within the vessel and may be supported above a bottom of the vessel. The electrodes generate energy that heats the vessel's open space, and melts inorganic portions of the waste and gasifies and dissociates organic portions of the waste into elemental components. These elemental components may be reformed into a synthesis gas which may be conditioned and cleaned to recovery a non-hazardous product.
