An ozone cleaning system includes a first chamber, a second chamber coupled to the first chamber, and a utility assembly disposed within the second chamber. The utility assembly includes an ozone generator configured to provide ozone to the first chamber, a humidifying unit configured to provide water vapor to the first chamber, and a blower configured to at least one of (i) reduce air pressure within the first chamber or (ii) draw the ozone from the first chamber following a decontamination process.

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.

A hierarchical catalyst composition comprising a continuous or particulate macroporous scaffold in which is incorporated mesoporous aggregates of magnetic nanoparticles, wherein an enzyme is embedded in mesopores of the mesoporous aggregates of magnetic nanoparticles. Methods for synthesizing the hierarchical catalyst composition are also described. Also described are processes that use the recoverable hierarchical catalyst composition for depolymerizing lignin, remediation of water contaminated with aromatic substances, polymerizing monomers by a free-radical mechanism, epoxidation of alkenes, halogenation of phenols, inhibiting growth and function of microorganisms in a solution, and carbon dioxide conversion to methanol. Further described are methods for increasing the space time yield and/or total turnover number of a liquid-phase chemical reaction that includes magnetic particles to facilitate the chemical reaction, the method comprising subjecting the chemical reaction to a plurality of magnetic fields of selected magnetic strength, relative position in the chemical reaction, and relative motion.

An ozone cleaning system includes a decontamination chamber, a utility chamber coupled to the decontamination chamber, and a utility assembly disposed within the utility chamber.
