Decontamination compositions useful to decontaminate potentially toxic materials, such as PAH and others, present on clothing comprise an aqueous solution of a water soluble cerium salt or a dispersion of cerium oxide in water. The decontamination composition may optionally include at least one of an oxidizer, a surfactant, a co-solvent, a chelating agent, and a polymer. Methods of decontaminating clothing involve applying the decontamination composition to the clothing.

According to an embodiment, a process apparatus performs processing on a byproduct generated in a reaction of a raw material including silicon and a halogen element or in a reaction between a raw material including silicon and a raw material including a halogen element. The apparatus includes a process liquid tank, a processing tank, a supplier and an exhauster. A process target member including the byproduct is introduced into the processing tank. The supplier supplies the process liquid from the process liquid tank to the processing tank and performs processing on the byproduct with the supplied process liquid. The exhauster exhausts a gas generated by reaction between the process liquid and the byproduct from the processing tank.

A method for destructing and valorizing an asbestos waste including the steps of: determining the asbestos mineralogical group contained in the waste, performing a treatment on the waste which includes of: an acid treatment when the waste comprises only a chrysotile, a base treatment when the waste comprises only an amphibole, the acid treatment followed by the base treatment when the asbestos waste includes a mixture of a chrysotile and an amphibole, and valorizing at least one of the products obtained on completion of the performing of the treatment. An embodiment also concerns a treatment of a chrysotile waste through an acid treatment followed by a thermal treatment.
