A method for remote control of decontamination of medical waste in an apparatus includes receiving, by a server via a first network interface and from the apparatus via a second network interface, a plurality of signals, the plurality of signals comprising operation data of the apparatus generated while the apparatus performs medical waste decontamination cycles in a first configuration; analyzing, by the server, the plurality of signals according to an operation policy; selecting, by the server, a first signal based on the analyzing the plurality of signals; and adjusting, by the server, operation of the apparatus by transmitting, via the first network interface, instructions to the second network interface of the apparatus, the instructions comprising the first signal, wherein receipt of the instructions causes the apparatus to perform a medical waste decontamination cycle in a second configuration different from the first configuration.

The invention includes a system and method for delivery and storage of an absorbent for solidification of liquid waste. The system includes a plurality of nestable containers configured to receive aqueous liquid to be solidified and forming a packet safe space when nested one within another. The system also includes a plurality of packets at least partially soluble in the aqueous liquid to be solidified. The containers include at least one packet and each packet contains a solidifier for use as an absorbent composition for the aqueous liquid to be solidified. A packet may be housed within the containers inside a packet safe space. The invention also includes an improved system and method for packaging a solidifier for solidification of liquid medical wastes.

Induction heating from an induction coil (108) is used to separate a metal medical sharp (144) from its holder (142) by applying a high-frequency oscillating magnetic field that excites eddy currents and resistance heating in the sharp. The heated metal sharp melts the adhesive or plastic securing the sharp to its holder. The use of induction heating is advantageous in that it does not require direct contact between the electrical circuit and the sharp or its holder. The heating can also act to sterilize the sharp and thereby render it less hazardous at the same time that it separates the sharp from its holder. The induction coil can have a stepped or conical shape to concentrate the RF energy at the interface between the metal sharp and its holder.

The present disclosure discloses a feeding system for treating liquid medical waste. The feeding system comprises a receiving container for storing liquid medical waste and a feeding container for accommodating a coagulant. The feeding container comprises an outlet and a seal for closing the outlet, and the receiving container comprises a feeding connector with a feeding channel. The feeding container and the receiving container are provided with a guide mechanism comprising guide lugs and guide slots, and the feeding connector is provided with a plurality of splitting portions arranged along the circumferential direction of the feeding channel and spaced apart from each other by a certain distance. The guide mechanism allows the operation of rotating the feeding container by a predetermined angle relative to the receiving container, and this operation causes the splitting portions to cut the seal along the circumference of the feeding channel to destruct the seal, thereby causing the coagulant accommodated in the feeding container flows into the receiving container through the outlet. The present disclosure provides a safe and convenient operation manner for adding a coagulant into a storage container of liquid medical waste.

The purpose of the present invention is to provide a method which is for producing pulp fibers for cellulose nanofiberization from pulp fibers of used sanitary products, and which can produce pulp fibers for cellulose nanofiberization that have low lignin content and a low distribution thereof and that have excellent cellulose nanofiberization properties. This method is described below. The method is characterized by involving: a step for supplying, from a mixed solution supply port (32) to a treatment tank (31), a mixed solution (51) which contains superabsorbent polymers and pulp fibers derived from used sanitary products; a step for supplying an ozone-containing gas (53) from an ozone-containing gas supply port (43) to a treatment solution (52) inside of the treatment tank (31); a step in which, by raising the ozone-containing gas (53) while lowering the superabsorbent polymers and pulp fibers in the treatment tank (31), the ozone-containing gas (53) is brought into contact with the superabsorbent polymers and the pulp fibers, and pulp fibers for cellulose nanofiberization are formed from the pulp fibers; and a step for discharging the treatment solution (52) from a treatment solution discharge port (33), wherein the pulp fibers for cellulose nanofiberization have a lignin content of less than or equal to 0.1 mass %.

Provided is a used paper diaper processing apparatus in which a water absorption function of a superabsorbent polymer that absorbs water contained in excrement is lowered and water is removed by mixing the superabsorbent polymer and a chemical containing divalent metal ions in an outer tank, and in which weight is reduced by dehydration after an amount of water contained in a used paper diaper is lowered. In the apparatus, a lower portion of the outer tank can be opened and closed, so that weight reduction processing and a series of operations including taking-out are possible. Since an operator is not required to take out the used paper diaper after processing directly from the outer tank, it is possible to reduce work and hygiene burdens on the operator.
