Remotely-controlled system for the in-situ treatment of infectious healthcare waste produced by small waste producers, comprising:

infectious healthcare waste collection and treatment devices intended to be installed at small-medium waste producers' premises to collect and treat infectious healthcare waste and designed to be compliant with use in venues intended for residential purposes, practicing a profession or providing a service, such as domestic venues, offices, medical, dental and veterinary practices, clinics, or the like, and

a remote control centre in communication with the infectious healthcare waste collection and treatment devices via a long-range communication system;

each infectious healthcare waste collection and treatment device comprises:

a sensory system to monitor operation of the infectious healthcare waste collection and treatment device; and

an electronic control unit connected to the sensory system and in communication with the remote control centre to transmit thereto data indicating operation of the infectious healthcare waste collection and treatment device and to receive therefrom and execute commands relating to operation of the infectious healthcare waste collection and treatment device;

the remote control centre is configured to receive and process data from the infectious healthcare waste collection and treatment devices and to monitor, control and report on the operation thereof based on the specific applications and/or users' needs.

A system for treating infectious medical waste is provided that includes a collection infrastructure, handling, and a shredding sub-system for feeding partially processed waste to an oxidizer to eliminate potential airborne infectious waste prior to transforming the medical waste into useful co-products. Waste generators of potentially infectious medical waste include, but is not limited to hospitals, medical offices, dental offices, clinics, laboratories, research facilities, veterinarian offices, and emergency medical service providers. The medical waste is collected from the waste generators, transported to a processing site in sealed containers, and transformed into value-added products including hydrocarbon based gases, hydrocarbon-based liquids, and carbonized material in a system proceeded by a negative pressure region and having as a transformative element an anaerobic carbonizer.

Featured are a two-stage grinder, an apparatus embodying same and methods related thereto. Such a medical waste grinder includes a first stage and a second stage. The first stage includes spring loaded cutter stacks mounted on two adjacent shafts between two edge plates, each of the cutter stacks including cutters arranged in a helix to create space, each cutter including a number of teeth per blade and including a major diameter and a minor diameter, each cutter turning opposite a fixed counter knife enabling a pinching action against the teeth of the cutter. The second stage includes spring loaded cutter stacks.

Efficient and adequate disposal of medical infectious waste is proportional to the reduction of the spread of infectious diseases and the disease itself among humans. The essence of this invention is that infectious medical waste is in a timely, fast, efficient, simple, and environmentally friendly safely disposed of and turned into inert-municipal waste. Previous methods and devices for the disposal of infectious medical waste involved long-term procedures for the collection, sorting and storage of infectious medical waste, which increases the risk of secondary infections. This invention skips the process of collecting, sorting and storing medical infectious waste, and the entire process in the invention takes place in three unbreakable phases whose end product is municipal-inert waste. It is important to emphasize that with this invention, even the smallest amount of infectious medical waste will be disposed of immediately in an appropriate manner. And as a result, a maximum control over all medical infectious waste is achieved.

Described herein are methods of recycling polypropylene based personal protective equipment. The method may comprise the steps of: (a) conveying a feed of personal protective equipment; (b) cleaning at least a portion of the feed of personal protective equipment; (c) fragmenting the personal protective equipment into a plurality of fragments, the plurality of fragments comprising non-polypropylene fragments and polypropylene fragments; (d) separating at least a portion of the non-polypropylene fragments from the polypropylene fragments to produce a batch of polypropylene fragments; and (e) pelletizing the batch of polypropylene fragments to produce polypropylene pellets.

A high crushing efficiency medical waste treatment machine includes a crushing cylinder, a crushing knife set provided at the bottom of the crushing cylinder, an intermittent material discharge mechanism set on one side of the crushing knife set, a pressurizing mechanism slidingly set along the axis of the crushing cylinder on the other side of the crushing knife set. The pressurizing mechanism includes a mounting frame slidingly connected to the inner wall of the crushing cylinder, the mounting frame rotatably connected to a material tumbling plate made of magnetic material; when the intermittent material discharging mechanism discharges material, the pressurizing mechanism moving in a direction close to the crushing knife set; when the intermittent material discharges mechanism stops discharging material, the material tumbling plate rotates.

Disclosed and claimed herein are devices for the treatment of medical waste using high temperature and pressure steam. The devices combine both the sterilization chamber and the steam generating component. The devices may be self-contained and may be movable by one person of average strength and ability. The devices which are self-contained require no special installation, connections, plumbing or permanent or semi-permanent electrical connections. Disclosed and claimed herein are methods using the disclosed and claimed devices.

A medication disposal apparatus and method of use with multiple stages of conversion operable to render a controlled substance useless.

A portable human and fibrous waste maceration and disposal system comprising a receiver vessel, a macerator and portable holding tank. Optionally it will be mounted on wheels or adapted for mounting on a removable cart. In some embodiments it will be a single multi-component system and in others a collection of units with detachable holding tank(s). Operation may be automated.

An infectious waste treatment system and method for decontaminating infectious waste employ a thermal friction extruder (20) in which first and second interleaved counter-rotatable augers (40, 42) include reverse pitch flight sections (62, 72) that urge waste material in a direction opposite to that of the flow stream and into engagement with the back sides of friction plates (50, 52). This increases the amount of heat generated by the extruder. The reverse pitch flight sections can be selectively replaced with forward pitch flight sections to control the amount of heat imparted to the waste material by the friction plates.
