The disclosed subject matter relates to a method of treating of asbestos or asbestos-containing material, comprising applying to the asbestos or asbestos-containing material a composition including a treatment compound comprising at least one of hexafluoro titanium di-ammonium, potassium hexafluoro zirconate. ammonium hexafluoro phosphate. ammonium hexafluoro stannate, ammonium hexafluoro germanate, ammonium tetrafluoro borate or ammonium heptafluoro tantalite; and a fluorine scavenger compound.

Chemical compositions may be used to dissolve coatings and at least partially encapsulate potentially hazardous fibers or potentially hazardous particles in the coating. The chemical composition for use in the removal of a textured or smooth surface comprising asbestos may comprise an aqueous solution comprising a surfactant package and triethyl phosphate. In certain embodiments, the surfactant package may comprise an alcohol ethoxylate surfactant and sodium lauryl sulfate.

Disclosed herein are systems and methods for a waste processing system. The system comprises a container preparation area wherein containers are prepared for in-container vitrification processes, a feed area where spent media, recycled waste, and one or more of glass frit, silica sand, or glass formers, are blended to form blended waste. The blended waste is metered into a prepared container from the container preparation area as electricity is applied to electrodes placed in the waste within the container, thereby creating heat sufficient to melt the contents of the container. This results in a container containing vitrified glass product with entrained contaminants. The system includes a container cooling area where the processed container may be cooled, and a container disposition area where the processed container may be surveyed, decontaminated, sealed, shielded, and/or prepared for storage.

Systems, methods, and other embodiments for removing contaminated materials such as asbestos from railcars (i.e., train cars and subway cars) for subsequent recycling of the railcars. In particular, a collapsible inner containment structure having a HEPA negative air pressure is used. A door on the inner containment structure is opened at one end of the inner containment structure and a railcar is transported into a work area located within the inner containment structure. The door is then closed so that the inner containment structure can maintain the negative pressure within the inner containment structure. The contaminated materials such as asbestos are removed from the inside of the railcar using a mixture of pressurized water and media.
