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 system for shearing bulk material includes a shearing cartridge with an input port and an output port. A first plurality of rotatable blades are disposed about a first shaft, Each of the first plurality of rotatable blades includes a center aperture such that the first shaft extends through the center apertures of the first plurality of rotatable blades to selectively rotate each of the first plurality of rotatable blades simultaneously. A second plurality of rotatable blades is opposingly offset from the first plurality of rotatable blades. Each of the second plurality of rotatable blades includes a center aperture such that the second shaft extends through the center apertures of the second plurality of rotatable blades to selectively rotate each of the second plurality of rotatable blades in a direction opposite the first plurality of rotatable blades to shear and reduce the bulk material.

An infectious medical waste treatment system includes system control means that electrically interlocks and integrally controls an infectious medical waste treatment apparatus, a cake cutting device, a cake shredding device, a flake conveying device, a flake temporary storage tank, a sealed-type flake supplying device, a heating, dry distilling and gasifying apparatus, a gas cooling and liquefying apparatus, an exhaust gas treatment apparatus, unburnt gas burner and an unburnt gas combustion apparatus.

A drying apparatus, particularly suitable for disposing water-containing organic waste. The drying apparatus includes a drying chamber with a circular cross-section, where waste enters the drying chamber through a waste inlet and undergoes rotational movement within the drying chamber due to a negative pressure generated by an air pump. The air pump draws out airflow from the drying chamber through an air duct connected to the flow outlet, ensuring that the waste continues to rotate during the drying process. Additionally, the apparatus is equipped with a microwave generating device, which directs microwaves into the drying chamber either directly or via a microwave conduit to efficiently dry the waste. This design combines the cyclonic motion with microwave heating, significantly enhancing drying efficiency and ensuring that the waste is fully dried in a short time, making it particularly suitable for disposing organic residue that requires rapid drying.

A low-cost, portable, destructive sanitization method for solid state drives (SSDs) is provided. Preferably, an SSD is destroyed by disintegration within a given time period (approximately 30 minutes or less) using a blending device operating at a given peak power, e.g., greater than 450 W. A pulverizing agent may be admixed with pieces of an SSD printed circuit board prior to initiating the disintegration process to increase the number of particle collisions in a processing/blending chamber. The pulverizing agent may also contain moisture that mitigates suspension of processed SDD particles in the surrounding air (when the mixing chamber is opened). The overall process may be video-recorded for compliance purposes.

An apparatus includes: a disposal unit; a control unit configured to stop operation of the disposal unit; and a metal detector coil and associated circuitry, the metal detector coil located such that waste passing into the disposal unit for shredding passes through the metal detector coil. The control unit is triggered to stop operation of the disposal unit upon the detection of metal passing through the metal detector coil.

A marine vessel designed for the collection, shredding, and pelletizing of oceanic plastic waste. The vessel uses renewable energy sources such as solar panels and wind turbines to power onboard systems, including AI-enhanced sensors that detect and target high-density areas of plastic debris. Once collected, the plastic is shredded and processed into uniform plastic pellets optimized for use in plastic asphalt production. The vessel also includes storage compartments for the pellets and a crane system for transferring containers filled with pellets to adjacent vessels or shore-based transport. This integrated system addresses inefficiencies in traditional ocean cleanup methods by enabling immediate onboard processing, reducing transportation needs, and repurposing plastic waste into a valuable industrial resource, while significantly minimizing environmental impact through sustainable energy use.

A processing assembly for processing kitchen organic garbage and waste of farms includes a tank with a grinder located therein. The grinder grinds the garbage and waste by blades and rotatable blades. A transition can is connected between the tank and a deodorant pool which has deodorant bacteria received therein to remove odors. A one-way filter is connected between the transition can and the deodorant pool. A vacuum pump is connected between the tank and the transition can to suck air in the tank to the deodorant pool and to separate water from the vapor air. The water is stored in the transition can. The volume and weight of the garbage and waste are reduced and no pollution is created to the air. Hard stuff from the organic waste is ground into small pieces without damage to the blades.
