An assembly and method for processing human waste includes providing a supporting base having an opening within which a waste reservoir is affixed. The assembly may be installed on or below a rim of a toilet bowl. Solidification and pathogen killing materials are provided. The materials are deposited in the reservoir either prior to or upon accumulation of waste in the reservoir. The reservoir with the solidified waste is then sealed and transported to a collection facility.

A process for immobilizing a mercury-containing waste, which comprises: stabilizing the mercury of the waste by precipitating the mercury as mercury (II) sulfide; thenencapsulating the waste by cementation, the cementation comprising coating the waste in a cement paste obtained by mixing a composition comprising a powder of at least one binder chosen from hydraulic cements, alkali-activated cements and acid-activated cements, with an aqueous mixing solution, then hardening the cement paste; and which is characterized in that the precipitation of the mercury as mercury (II) sulfide is obtained by reacting the mercury with a thiosulfate in a basic aqueous medium, while stirring and in the presence of a sulfide of an alkali metal, the molar ratio of the thiosulfate to the mercury being at least equal to 1. Applications: immobilization of any mercury-containing waste regardless of the origin thereof and, in particular, of mercury-containing waste from nuclear facilities.

Disclosed are materials for decontamination of compounds having a phosphorous-sulfur bond or a phosphorous-oxygen bond. A porous polymer, such as poly(dicyclopentadiene), contains particle of zirconium hydroxide. The polymer optionally has hydroperoxide groups.

A polymeric polysulfide is disclosed. The polymeric polysulfide is formed by reacting a fatty acid composition comprising at least one unsaturated fatty acid or derivative thereof with sulfur, at a weight ratio between 9:1 and 1:9, under inverse vulcanisation conditions to produce a polymeric polysulfide wherein at least 50% of the fatty acids or derivatives thereof in the fatty acid composition are unsaturated.

The potential for substance abuse involving residual amounts of abusable substances remaining in used skin-worn patches is reduced by the provision of a system and method for combining the abusable substance with a separate anti-abuse substance agent as part of a removal or disposal procedure.
