Abstract: A method for destroying asbestos in mainly organic matrix asbestos-containing waste includes the steps of: preparing the asbestos-containing waste; preparing a supercritical aqueous phase; letting the asbestos and the primarily organic matrix of the asbestos-containing waste react with the aqueous phase for a time t in an appropriate reactor at a predetermined pressure P and temperature T to maintain the aqueous phase in supercritical condition; cooling and condensing the aqueous phase flowing out of the reactor; and separating the aqueous phase from any entrained solid products therein. The step of preparing the supercritical aqueous phase includes an additional step, in which an oxidizing compound is added in a predetermined concentration Cl, the pressure P is in a range from 25 to 27 MPa, and the temperature T is in a range from 600° C. to 650° C., causing the asbestos and the organic binder to be simultaneously destroyed.

Abstract: A method for destroying asbestos in mainly organic matrix asbestos-containing waste (ACW), which includes the steps of: preparing the asbestos-containing waste; preparing a supercritical aqueous phase; allowing asbestos and the primarily organic matrix of the asbestos-containing waste to react with the aqueous phase for a time t in an appropriate reactor at predetermined pressure P and temperature T to maintain the aqueous phase in supercritical conditions; cooling and condensing the aqueous phase flowing out of the reactor; and separating said aqueous phase from any entrained solid product therein. The step in which the supercritical aqueous phase is prepared includes an additional step, in which at least one oxidizing compound is added in a predetermined concentration C1, the pressure P is in a range from 25 to 27 MPa, and the temperature T is in a range from 600° C. to 650° C., causing the asbestos and the organic binder to be simultaneously destroyed.
