Apparatus and method in converting municipal solid waste into geo-polymer briquettes and geo-polymer bricks comprising bag opener cum crushers, magnetic separators for ferrous and-eddy current separators for non-ferrous things; squeezer for removing liquid content; inter particle collision driers for drying; pulverizer for pulverizing, and devolatizing carbonization reactor for carbonisation of combustible MSW to produce solid char with low water content. Solid char is mixed with geo-polymer binding agent/starch/tar/to form combustible pellet/briquette. These highly combustible briquette/pellets have high calorific value. The pellet/briquette is formed by rotating combustible char at high rpm and compaction. Pellet has a water content of less than 5% by weight and fuel value of 5500 to 6500 KCAL. This process produces non-combustible geo-polymer brick. The non-combustible MSW separated by a trommel is crushed by inter particle collision crusher and pan mixers mixing with geo-polymer binding agent/fly ash/quarry dust/chips or china clay and moulded.

A method and system for coal ash reclamation from a land fill, the system comprising: a harvester; a screen for screening non-ash material from ash collected by the harvester; a dryer for drying raw ash thereby creating dried coal ash and fine particulate ash; an exhaust pipe to direct the ash to a dust collector; a crusher for crushing the dried ash; a classifier for classifying the crushed dried ash; and a storage container for storage. The method comprising: harvesting raw coal ash from a land fill; screening the raw coal ash to remove oversize materials; drying the screened ash to remove water; crushing the stream of dried ash; classifying the crushed ash into fine particulate ash and large particulate ash, the second stream being directed for further crushing; streams of fine particulate ash being cooled; and storing the fine particulate ash.

Provided is a food waste disposer. The food waste disposer according to a concept of the disclosure includes: a housing; a grinding device positioned inside the housing and configured to grind food waste; and a storage device positioned below the grinding device and storing the grinded food waste, wherein the grinding device includes: a grinding case configured to grind the food waste, and including an outlet opening to transfer the food waste to the storage device; and a valve assembly positioned below the grinding case and opening and closing the outlet, the valve assembly being separable from the housing together with the grinding case.

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.

Systems, apparatus, and methods for recycling battery cells and/or battery cell assemblies for metallurgical recovery. In some embodiments, the battery cells and/or battery cell assemblies can be discharged/deactivated, reduced to smaller pieces, thermally decomposed, and then sorted into different component materials.

A waste processing machine for reducing material and having a docking safety system. A cutting assembly on a frame reduces material. A feed system on the frame directs material toward the cutting assembly. A winch assembly includes a line with a line end for securing material, and a driver on the frame to urge the line end toward the driver. A keeper fixed to the frame secures the line end to the frame. A docking subassembly, spaced from the keeper, is movable between: a docked position with the line tensioned against the subassembly between the driver and the line end secured to the keeper; and an undocked position with the line loosened against the subassembly. A control unit allows operation of the feed system when the subassembly is in the docked position, and at least partially limits operation of the feed system when the subassembly is in the undocked position.

An under-sink disposal unit includes a motor, a disposal chamber, and a disposal throat. The disposal throat extends from the disposal chamber to an opening in a top of the disposal unit and defines a passageway through which objects pass into the disposal chamber for grinding. The disposal unit further includes a coil assembly including an arrangement of coils. The arrangement of coils is used to detect the passing of a metallic object in the passageway through the disposal throat. Furthermore, the arrangement of coils includes at least one coil having a loop that is oriented with respect to an axis of the passageway through the disposal throat such that objects passing through the disposal throat into the disposal chamber pass by and proximate to, but do not pass through, such loop. Preferably DC injection braking is used to stop the motor upon detection of a metallic object.

A composting garbage disposal for under sink use in a kitchen which separates food waste items into liquid and solid components. The liquid components are directed to a standard sewer or septic system. The solid components are directed to a removable storage bin. The food waste items are separated by use of a motor driven auger member which is in close proximity to the inside wall of a screened cup so that the liquid exits the screened portion of the cup and the solid exits through an aperture in the floor of the cup. A microprocessor circuit senses the strain on the drive motor and if the strain becomes excessive, automatically reverses the direction of the shaft and auger thereby releasing excess food waste that is causing the excess strain.
