Method and stationary or movable device for neutralizing and recycling asbestos waste
The asbestos waste neutralization device (10) comprises: an acid tank (23); a vessel (16) containing a diluted acid solution, into which waste comprising asbestos is thrown, said acid solution neutralizing the asbestos waste; a filtration unit (21) for separating, at the end of the reaction for neutralizing the waste, the inert solid from the acid solution liquid phase; a unit (22) for regenerating the etching acid solution that adjusts the hydrogen potential of the extracted liquid phase by adding concentrated acid contained in the acid tank; and a means for transferring the regenerated solution into the vessel.
