Abstract
A waste disposal system for gasification and melting of various waste materials such as solid waste, waste in a solid container, granular waste, and liquid waste, and mixtures thereof. The system includes a reactor vessel which is closed to the atmosphere, and also includes a bottom portion capable of serving as a slag pool. An active feed mechanism eliminates the entry of air from the atmosphere into the vessel and also blocks the expulsion of by product gases into the atmosphere. The feed mechanism includes mechanisms to feed solid waste, waste in a solid container, granular waste and liquid waste into the reactor vessel. A plasma arc torch is located for plasma arc activity within said reactor vessel to produce a high temperature processing zone to gasify or melt solid waste, waste in a solid container, granular waste, and liquid waste and mixtures thereof as such waste is actively fed into the reactor vessel. In preferred embodiments a waste receiving reservoir is located within the vessel and positioned to initially receive and retain waste from the active feed mechanism for thermal decomposition and melting of the waste by the arc torch.
