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.

The present invention relates to a system for continuously treating solid waste and an associated process based on steam injection at a temperature greater than 100° C. and at a pressure greater than the atmospheric pressure, which allow a high productivity to be achieved, require a smaller volume of the pressure vessel needed carry out the solid waste treatment, and reduce the amount of steam needed to carry out said treatment.

This present invention is a convenient automatic apparatus for handling sewage and grey-water which is tapable of removing waste from a waste holding tank, disinfecting a holding tank, and further allowing waste to be moved into a sewer or septic system through the use of a plurality of electric servo motors, sensors, cameras, hoses, booster motor, actuators and hydraulic system. This present invention can receive and transmit data via a wireless communication system, record information about the amount of waste product received and can communicate with the server software, generate a bill and generate a receipt. This present invention can allow a Recreational Vehicle, Autonomous Vehicle, Automobile, Travel Trailer, Airplane, Boat, Portable Toilet, Railroad Passenger Car, in a designated area, to connect the automatic electric electronic waste handling apparatus to the Release Mechanism affixed to a variety of vehicle holding tanks to remove waste from a black water, grey water holding tank, clean the holding tank and disinfect the holding tank. This present invention allows the vehicle to automatically dispose of waste matter, urine, feces, toilet paper and grey-water hands free in a manner that is safe for the environment and the end user, allowing for greater ease of use and efficiency as well as increased profits for businesses through labor savings.

The present invention relates to a pressurised-vapour autoclave characterised in that, in addition to sterilising instruments in a main chamber, it allows a second or third hermetic, exchangeable sterilising chamber to be housed inside the autoclave and connected, by means of a quick connection, to the main sterilising chamber, thus allowing access to the internal components of the autoclave such as compressors, water heaters, solenoid valves, etc., in order to sterilise sanitary waste without contaminating the main chamber with steam or ozone gas, thereby producing two or three completely autonomous and separate chambers. The present invention also relates to a method for operating the autoclave, wherein the autoclave reports the number of kilos treated by means of weight sensors on the feet of same, as well as all the internal parameters thereof by means of a GPRS-SIM circuit board.

In one aspect, a composition for decomposing pharmaceutically active agents comprises an oxidizer comprising a permanganate, and an isocyanurate; and an immobilizer. In another aspect, a composition comprises up to 50 wt. % of an oxidizer comprising potassium permanganate and sodium dichloroisocyanurate dehydrate, wherein the wt. % is based on a total weight of the composition.

A multi-stage lid ultraviolet sterilizing waste container is disclosed which contains a housing, base, lid assembly, support structure for receiving flexible bag assemblies and at least one UV light source for sterilizing the inside of the container. The waste container further includes sensors and motors to automate certain steps.

Mixed solid waste is transported from a waste collection vehicle to a first room of a waste treatment facility. The first room defines an enclosed isolation zone that is configured to receive the mixed solid waste from the waste collection vehicle. The mixed solid waste is treated in at least one process vessel in the first room to destroy a majority of pathogens in the mixed solid waste to yield a sanitized waste. The sanitized waste is transported to a second room of the facility. The second room defines a clean zone that is separated from the first room by a barrier.

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.
