Abstract

The method according to the invention enables a facility having a rather reduced dimension, for incinerating to be used, melting and vitrifying mixed waste () introduced into a reactor (), by means of a basket () in turn passing through an air lock (). Plasma torches () burn all waste () contained in the basket (). The waste is then lowered in a melting bath of a furnace () with an inductor () including a crucible-forming container (). A combustion gas treatment train completes the facility. The furnace () can be dismantled, after a series of treatments of several baskets () of waste () for disassembling the crucible-forming container () from the furnace (). Application in treating different radiologically contaminated and/or toxic mixed waste.
