In one embodiment, the invention discloses a hygienic odor reducing agent, characterized in that it comprises 0.25 kilograms of caustic soda in powder form, 0.25 kilograms of soda ash, 1 ml of chloroform and 5 ml of tide scent. Further disclosed is a process of preparing the hygienic odor reducing agent in sanitary areas which comprises the steps of pouring 10 liters of water in a container, adding 0.5 kilograms of chlorine, adding 0.25 kilograms of caustic soda, adding 0.25 kilograms of soda ash, adding 1 ml of chloroform, adding 5 ml of tide scent and stirring the whole mixture daily for 3 days.

A method of recycling superabsorbent polymers derived from a used absorbent article, the method including: treating the superabsorbent polymers with ozone water after inactivation; reactivating, with an alkaline aqueous solution, the superabsorbent polymers treated with the ozone water; and adding hydrophilic fine particles to the superabsorbent polymers reactivated with the alkaline aqueous solution and then drying the superabsorbent polymers.

An apparatus includes a notification unit configured to notify a user of information, and a controller configured to identify at least one unit based on an operation performed by the user among a plurality of units included in the apparatus, wherein the notification unit can notify the user of first information indicating the identified at least one unit and second information regarding disinfection of the identified at least one unit.

To provide a method for disinfecting air and/or surfaces which can be carried out truly continuously, in particular for essentially 24 hours a day, with people and/or animals present, the a method for disinfecting air and/or surfaces is proposed, wherein a disinfectant is dispersed continuously into a volume and/or area to be disinfected, wherein the disinfectant comprises electrolyzed and/or sterilized water containing hypochlorous acid, and wherein the disinfectant is dispersed at a dispersion rate between 0.5 ml/m.sup.3/h and 12 ml/m.sup.3/h.

An apparatus that disinfects hand-held devices has a sealed interior disinfecting chamber designed to fit handheld devices of various sizes and surround them with disinfectant in a gaseous state. The base of the interior chamber has vertically disposed pegs of equal height that serve as an aerated pedestal on which to place a handheld device to allow gas to circulate beneath and around it. A fan evaporates disinfectant from the sealed chamber prior to unsealing the chamber.

A method and corresponding apparatus for cleaning an enclosed space by in situ generation and distribution of hypochlorous acid. The method includes selecting an apparatus comprising a container, placing the apparatus in the enclosed space, activating generation of hypochlorous acid from the container of the apparatus, distributing hypochlorous acid throughout the enclosed space as the hypochlorous acid is generated; and allowing the distributed hypochlorous acid to dwell in the enclosed space for an effective time.

A disinfection system including an enclosed chamber and a source of a disinfecting vapor connected to the enclosed chamber, wherein the disinfecting vapor includes nitric acid. Methods of disinfecting a contaminated article are also described, the methods including placing the contaminated article within an enclosed chamber of a disinfection system and exposing the contaminated article within the enclosed chamber to a source of a disinfecting vapor including nitric acid for an exposure time sufficient to disinfect the contaminated article by achieving a reduction in colony forming units of the disinfected contaminated article relative to the contaminated article. Exposing the contaminated article within the enclosed chamber to the source of the disinfecting vapor may include alternately exposing the contaminated article to the disinfecting vapor for a first time interval, and exposing the contaminated article to a water vapor for a second time interval.

A decontamination method is a decontamination method for decontaminating the inside of a decontamination target by removing at least one of microorganisms and viruses present in the decontamination target. This decontamination method includes a step of releasing vapor containing peracetic acid into the decontamination target, without releasing mist containing peracetic acid. An average humidity inside the decontamination target during decontamination is RH82% or more. A peracetic acid vapor load that is a value obtained by adding a concentration of peracetic acid in the vapor every minute from a start of decontamination to a completion of decontamination is 2000 ppm or more.

An internet-of-things (IOT) robotic sterilization system that operates autonomously for use in the prevention of diseases, e.g., Coronavirus Disease 2019 (COVID-19), caused by pathogens such as coronavirus SARS-CoV-2 and other pathogens present within an interior space is described. A robotic sterilization device is communicatively coupled to the IOT base module via an IOT network, and includes a misting or fogging system fluidically coupled to a liquid reservoir, a sensor module including plurality of sensors, a controller, and a locomotion system. The robotic sterilization device navigates a path within the interior space while creating a disinfecting mist with the misting system, and may coordinate with other IOT-connected devices, such as the HVAC system, UV Vent sterilizers, scent dispensing appliances, and others to more efficaciously sanitize the interior space to protect humans by eliminating pathogens.
