A disposable, single-use wipe that can be used deodorize, disinfect, and/or sterilize an object. A wipe includes a flexible membrane or cloth-like element that may apply, distribute, and/or remove a treatment agent to, over, or from a surface of the object. A treatment agent, such as micron-, or nano-sized particles of a disinfectant or sterilant chemical, Ozone, negative ions, Hydroxyl radicals, or alcohol, etc., may be applied to the surface by the wipe or another applicator. An additional treatment agent (e.g., Triclosan, Chlorine dioxide, Hydroxyl radicals, etc.), may be associated with a wipe to enhance biocidal activity. The wipe may be used alone, in combination with a holder, or in combination with an applicator of energized treatment agent. An applicator and/or a holder may be used to energize one or more treatment agent to improve its efficacy.

The present disclosure relates to a flue gas treatment system (e.g. a multi-pollutant flue gas treatment system) for removal of greenhouse gases such as SO.sub.2, NO, NO.sub.2, H.sub.2S, HCl, water and CO.sub.2 as well as heavy metals (e.g. mercury, arsenic, bismuth, cadmium, lead and/or selenium) from the flue gases of fossil-fueled utility and industrial plants by reacting the raw flue gas, firstly, with chlorine in a gas-phase oxidation reaction and recovering the resulting products as marketable products, and then, secondly, treating the cleaned gas, which includes CO.sub.2, with a Sabatier reaction to produce a hydrocarbon fuel (e.g. methane). The system also includes an electrolytic unit for electrolyzing HCl to produce hydrogen gas for the Sabatier reaction as well as chlorine gas, which may then be recycled into the reactor.
