Abstract: A method for reusing waste including organic components in a bath of molten salt including providing to a reactor, at least one salt or a mixture of salts including at least one alkali metal hydroxide, providing the waste to the reactor, heating the at least one salt or mixture of salts in the reactor at a temperature above the melting point of the salt. Thus, the provided salt melts to form a liquid reaction medium, and induces an at least partial oxidation of the organic components. At least one compound resulting from this oxidation is recovered. At least one alkali metal hydroxide includes water of crystallisation, acting as oxidising agent for the organic compounds in the reaction medium, in such a way as to participate in the production of dihydrogen, the latter being recovered for the reuse thereof.
