Method and system for neutralizing asbestos

A system for asbestos neutralization, that comprises a neutralization unit comprising, in an atmospheric containment:

• a module configured for sorting of asbestos waste,
• an asbestos waste grinder, which is configured reduces the size of the asbestos waste to a dimension ranging from one-tenth of a millimeter to one millimeter,
• a concentrated sulfuric acid tank,
• a vat containing a hot diluted acid solution, for which temperature is between 70° C. and 100° C., in which grinded asbestos waste containing asbestos is dipped, said solution is configured for neutralizing asbestos contained in the grinded asbestos waste,
• a filtration unit to separate, at the end of the neutralization reaction, a solid inert waste from a liquid phase of the diluted acid solution,
• a regeneration unit for the diluted acid solution, which adjusts the hydrogen potential of the extracted liquid phase by adding concentrated sulfuric acid from the tank, and
• means for transferring the regenerated solution into the vat.
