An installation for destroying waste comprising at least traces of energetic materials, wherein the installation comprises:

• an enclosure delimited by lateral walls, a base and a roof, the enclosure being at least partially filled with a liquid medium, preferably water, up to a first level;
• a chamber comprising:
• an inlet, said inlet being intended to supply the chamber with waste to be destroyed by combustion in the chamber;
• an outlet;
• the chamber being immersed in the liquid medium of the enclosure, the inlet of the chamber opening at one of the lateral walls of the enclosure,
• a discharge line extending between a first end and a second end, the first end being connected to the outlet of the chamber, the second end being situated in the liquid medium, preferably in the vicinity of the base of the enclosure, the discharge line rising, between its first end and its second end, to a second level which is higher than the first level, the discharge line being configured to discharge, at the second end in the liquid medium, gases and volatile solid residues which are produced in the chamber during combustion.
