The present invention comprises a method of shredding treated medical waste, cleaning it of all traces of biological gunk, and sorting it into separate components for recycling. To clean biological gunk from materials, all materials must be first shredded into small parts to expose the interior. The cleaning is performed by submerging the gunk coated materials into a caustic solution that breaks down and dissolves the gunk off of the materials. The caustic solution may comprise sodium hydroxide, potassium hydroxide, or a similar chemical, which is highly effective in producing a corrosive chemical that can break down blood, bone marrow, urine, unused medication, food waste, organs, tissues and any other biologic materials. After all of the biological material is removed from the cleaned materials, they are sorted into component materials, such as plastics, metals, rubbers, glass, etc.

Control apparatus and corresponding method for controlling a high power electric motor, preferably of the order of megawatts, preferably of or associated with a shredding plant which is preferably usable for shredding very bulky and heavy objects and is provided with a rotating shredding member connected to the rotor of the electric motor, where a control circuit is configured to control the electric motor so that it can operate selectively in different operating modes.

This application discloses a separator for separating and recovering materials from a waste stream. The separator has a cyclone having a top section and a bottom section, an impeller within the cyclone, a media inlet for accepting a flow of media or a pulsating flow of the media operatively connected to the impeller in which media or fluid flows through the impeller into the separator; a first discharge passage for a collecting a light fraction, and a second discharge passage for collecting a heavy fraction.

A system and method for reclaiming select components containing rare earth metals of electronic media electronic storage devices such as hard disk drives, solid state drives and hybrid hard drives and destroying the data containing components thereof comprising first devices to loosen various components of the storage device, the components including the components containing the rare earth elements and the data containing portions. Second devices are provided for removing components from the storage device. A holding chassis receives the storage device, and moves the storage device for engagement with the first and second devices. A section is provided for destroying the data containing portion of the electric storage device when it is removed from the storage device.

A disclosed system and method are configured to process waste via a frontend processing module configured to crush, grind, aggregate and concentrate waste from a coarse material to a finer material including an iterative reprocessing of any oversized components. The disclosed system also includes a classifying module to separate the coarse material from the finer material via a process water and at least one microgrinder and fractioning centrifuge. The disclosed system further comprises a backend processing module configured for further classifying the respective coarse and fine material for energy production and dewatering, recovering and combusting component materials. System submodules are configured to microgrind and gasify or pyrolize a resulting particle slurry into a combustible synthetic gas release for electricity generation and heat. The system is applied to waste recovery of waste glass, electronics waste, coal piles, coal water fuels, biofuels, algae lipid oils, and various precious minerals.

A plant for the treatment of car fluff is disclosed having one or more magnetic iron separators, followed by one or more eddy current separators that receive the negative coming from the magnetic iron separators, followed by one or more inductive sensor-based recovery separators that receive the negative coming from the eddy current separators, followed by at least two inductive sensor-based polishing separators respectively calibrated for the separation of stainless steel and copper wires arranged for receiving the material separated by the inductive sensor-based recovery separators, an unravelling shredder also being arranged between the latter and the polishing separator(s) calibrated for the separation of copper wires.

Control apparatus and corresponding method for controlling a high power electric motor, preferably of the order of megawatts, preferably of or associated with a shredding plant which is preferably usable for shredding very bulky and heavy objects and is provided with a rotating shredding member connected to the rotor of the electric motor, where a control circuit is configured to control the electric motor so that it can operate selectively in different operating modes.

A separation device includes a first shredding unit, a first beating unit, and a first separation unit. The first shredding unit shreds a disposable diaper (processing target) containing a plastic (first material) and a water-absorbent polymer (second material) adhering to the plastic. The first beating unit beats the disposable diaper shredded by the first shredding unit with a first beating member, thereby promoting dissociation of the water-absorbent polymer from the plastic. The first separation unit rotates a first tubular portion in a state in which the disposable diaper beaten by the first beating unit is accommodated therein, thereby separating the water-absorbent polymer passing through first holes from the disposable diaper.

A modular system and method for producing urea from bio-mass includes means and steps for “homogenizing” a biomass feedstock stream having components with different bulk density BTU content into a stream having a consistent bulk density BTU content. The steps include cleaning the incoming bio-mass feedstock stream to remove non-organic matter, blending the cleaned bio-mass feedstock stream to obtain a homogeneous blend having a consistent bulk density BTU content, and milling the homogeneous blend bio-mass feedstock stream to a predetermined size no greater than 12 mm.

A method and apparatus for deconstructing a mattress of the type having steel coil springs held within fabric pockets. The apparatus includes a frame and an opener mechanism mounted to the frame and operable for opening a plurality of fabric pockets at a first end thereof to create an opening in the first end of the fabric pockets and expose the steel coil springs contained therewithin. A gripper mechanism is provided for gripping the plurality of fabric pockets at a second end thereof, opposite the first end. An extractor mechanism is mounted to the frame for extracting the steel coil springs from the fabric pockets through the openings formed in the first end of the fabric pockets.
