A pulverizer is provided having a top having an inlet and a bottom having an outlet. A modular drum has a drum housing wall with a plurality of planar panel portions extending between the top and the bottom and connected together. A drum liner is disposed inside the drum housing wall, the drum liner including a plurality drum liner portions to attached to the planar panel portions, each drum liner portion being at least partially planar and extending along a corresponding planar panel portion, each drum liner portion being detachable from the planar panel portion independently from the other drum liner portions. A rotating shaft is mounted within the modular drum and has radially extending arms creating flow currents within the pulverizer for reducing a size of product input fed into the inlet and producing a size reduced material that is discharged through the outlet.

Disclosed herein are systems and methods for processing waste egg shells into (i) a first product including calcified egg shell particles having diameters of 3μ or less, and (ii) a second product including calcified egg shell particles having diameters in a range from about 3μ to about 7μ. The first product may be used as a CaCO.sub.3 substitute for paint compositions and plastics compositions. The second product may be used as a CaCO.sub.3 blasting media substitute for use with abrasive blasting equipment.

An aggregate production method includes procuring stone waste by-products, sorting the stone waste by-products by type and color, and subjecting the sorted stone waste by-products to a two-stage crushing process to produce aggregate. The aggregate is screened into different sizes and placed according to size into a bag or container.

A pulverizer has arms connected to a vertically oriented rotating shaft at hubs. The arms are angled relative to radians extending from the shaft to be canted or offset. Pads can be oversized relative to the arms while being one of coplanar with the arms or recessed while possibly also having their radially inward face(s) angled to assist in resisting catching material thereon. A mechanical fuse connection can assist in connecting arms to the hub to prevent dangerous situations as well.

Aspects of the present disclosure include devices, systems, methods, and control systems for processing waste into usable products, such as fuel stock, soil additives, and usable byproducts. Various system components may include: 1) a material loading area; 2) a pre-shredder; 3) a magnet based separator; 4) an eddy current separator; 5) additional sorting devices, such as a ballistic separator and/or an optical separator; 6) a mechanical pulverizer, such as a vertical shaft impactor (VSI); 7) a moisture separation device, such as a cyclone; 8) a compressor, such as a ram baler; 9) a packager, such as a bale wrapper; 10) analyzers, such as for moisture and caloric data analysis; 11) a thermal pressure chamber, such as a thermal screw; and 12) a control system to control operation of the system.

A 3 in 1 reverse vending machine. A vending machine that is solar powered and accepts bottles and cans made of plastic, aluminum, and glass. The machine includes a conveyor system, barcode reader and cleaning system, this prepares the bottle and cans to be shredded and then granulated into small pieces. The machine houses a delivery system that carries the smaller pieces of processed material to its predetermined receptacle for storage. Each bottle and can has a monetary value once received by the machine that will be issued to the user once all bottles and cans are received and calculated per user per transaction.

An apparatus and a method for composting organic material. The apparatus comprises a container (10) having a first end (11), a second end (12) in the form of a hemispherical wall, and a jacket (13) extending between said ends. The container operates in an inclined (al) position. A transporting and mixing device (30) in the container transports organic material in a transport direction (L1) from the first to the second end and simultaneously mixes the organic material. The transporting and mixing device directs the organic material towards the hemispheric wall, whereby the organic material is first directed upwards along the hemispheric wall and then turned back against the transport direction. A fluffing device (40) in the container comprises a shaft (41) being perpendicular to the transport direction (L1) and cutter blades (50) extending outwards from the shaft (41).

A portable shredder unit includes a lightweight housing with an interior cavity divided into a battery storage cavity and a collection cavity, said housing includes a top opening, two opposite ends, two opposite side walls, and a floor; a removable lid attached to said top opening on said housing; a high capacity electric shredder component configured to shred paper, said shredder component includes at least one feeding slot opening, an electric shredding mechanism, and electric motor and an exit discharge opening said shredder component being oriented on said lid so that said feeding slot opening is exposed when the lid is placed over the top opening of said housing and said exit discharge opening is oriented above and over said collection cavity in said housing so that shredded material exiting the exit discharge opening is deposited into said collection cavity; at least one pair of wheels attached to said housing near one said end; a handle attached to said housing; a GFCI receptacle having a ground wire; a 110 VAC main cable with a male electrical plug attached to one end configured to manually plug into an external 110 VAC female plug, and an opposite end being connected to said GFCI receptacle; at least one 12 VDC rechargeable battery located inside said battery storage cavity; an inverter configured to convert 12 VDC into 110 VAC, said inverter connected to said rechargeable battery to convert 12 VDC current into 110 VAC, said inverter; a control panel or set of switches electrically connected to said shredder, to said inverter and to said GFCI receptacle, said control panel or set of switches are configured to allow an operator to select the source of electricity either from said GFCI receptacle when said main cable is connected to an external 110 VAC female plug or from said inverter when connected to said rechargeable battery; and a ground roller ball attached to the floor of the housing and configured to contact a surface under the housing when the portable shredding unit is placed onto the surface said ground roller ball electrically connected to the ground wire of said GFCI receptacle.
