A reagent set includes an oxidant, acid, and adsorbent, which is used in a method for reducing the leachability and release of PFAS, mercury, and other contaminants from soils, sediments, and other solid materials or waste when treated materials are exposed to acid rain, snow melt, runoff, landfill leachate, etc. The reagents are mixed with a quantity of contaminated material and water is added as needed in order to reduce the leachability of the contaminants from the treated host material, where the admixture end-product suitably removes contaminants from fluids that contact and/or otherwise permeate and/or pass through and/or around the treated admixture. The reagent set and method of use offer environmental professionals long-term, economically viable waste management solutions for removing contaminants from contamination source areas, spill and manufacturing release sites, impacted media, and landfills, as well as from the fluids that contact reagent-treated material.

This invention refers to a method for preparing a chemical digester characterized by using organic and inorganic elements used for multiple purposes such as an accelerator in the decomposition of organic matter, as a water flocculant, as an organic soil fertilizer and as a means to eliminate the concentration of flies and other inserts in organic matter to decompose. The method comprises heating water in a reactor at a temperature of 38 C., adding a polysaccharide, an anti-thickener and an antifoam. The method then comprises the addition of two organic acids, one of them previously mixed in a second reactor and, finally, an inorganic acid until the mixture is homogenized. Optionally the method comprises the packaging of the mixture and the treatment of organic matter.

Decontamination compositions are described. The decontamination composition comprises 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 are also described.

Processes and apparatuses for degrading PFAS into calcium fluoride, carbon dioxide, and water. PFAS are heated and introduced to a calcium base which will degrade the PFAS. The PFAS may be in a stream that is a PFAS enriched stream formed by desorbing the PFAS from an adsorbent which removed the PFAS from a contaminant stream. The PFAS may be desorbed in the presence of the calcium base. The calcium base may be calcium hydroxide, calcium oxide, calcium carbonate, or combinations thereof.

Disposal means for large scale efficient disposal of medication and controlled substances comprising a homogeneous mixture of one or more surfactants, aerobic enzymes, anaerobic enzymes, soluble bitterants, insoluble bitterants, colorants, excipients, thickener agents, and humectant. Unwanted medication and controlled substances, such as opioids, are introduced to the solution and rendered inert and/or useless.
