Title: METHOD FOR BIOLOGICALLY REDUCING THE QUANTITY OF MAGNESIUM, OR THE QUANTITY OF MAGNESIUM AND IRON, IN AN ASBESTOS WASTE PRODUCT
Abstract:
The invention relates to a method for biologically reducing the quantity of magnesium and/or iron in an asbestos waste product, characterised in that at least some of the iron and/or magnesium, which is contained inside said waste product or is on the surface thereof, is extracted by bringing said waste product into contact with siderophore-producing bacteria and/or bacterial siderophores until a modified waste product consisting of a solid phase and a liquid phase is produced.
