An improved waste stream homogenizing apparatus and method includes a housing with an inlet port configured to receive a waste stream and direct the waste stream to an exit port. A central shaft configured to rotate within the housing. A blade with a cutting edge connected with a blade hub, where the blade hub is connected with the central shaft and a sizing screen with sizing holes, the sizing holes arranged in a non-concentric pattern on the sizing screen, where the cutting edge of the blade is in contact with the sizing screen where the waste stream is forced past the cutting edge and the sizing screen as the central shaft rotates.

Crushing mill including a crushing chamber, an inlet pipe of the refuse to be crushed connected to the crushing chamber, and a thruster member associated to the inlet pipe; the crushing mill includes a compactor apparatus for the refuse to be crushed provided with one or more presser elements positioned in correspondence to the inlet pipe of the refuse to be crushed and configured to be moved from at least a first inactive position, in which they allow the loading of the refuse to be crushed into the inlet pipe, to at least a second active position in which they compact the refuse in the pipe; the mass of compacted refuse in the inlet pipe is sent to the crushing chamber by means of the thruster member.

A crushing mill includes a crushing chamber and a feed unit to feed the waste to be crushed positioned upstream of the crushing chamber. Upstream of the feed unit a first aperture is positioned for the inlet of the waste to be treated in the feed unit and, downstream of the feed unit, a second transfer aperture is positioned to transfer the waste to be treated toward the crushing chamber. The feed unit includes a member rotatable around a determinate axis and provided with at least a pair of cylindrical sectors angularly offset with respect to the axis, provided with corresponding inlet and discharge apertures of the waste to be crushed and configured so that, in any loading and/or crushing step of the waste to be crushed in the crushing mill, they prevent the first and second apertures from coming into communication with each other.

A waste processing apparatus is disclosed, comprising a waste processing vessel for holding waste and treatment fluid during processing; and a blade arrangement provided in the waste processing vessel, for shredding the waste; the waste processing vessel comprising a waste processing zone, in which fluid can be retained, such that waste provided to the waste processing vessel can be shredded by the blade arrangement and immersed in treatment fluid in the waste processing zone. A related method of waste treatment is also disclosed, as is a use of a solution comprising a disinfectant and a diluent in the treatment of biohazardous waste, wherein the disinfectant comprises peracetic acid and hydrogen peroxide.

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.

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 mobile polystyrene foam waste recycling method and system are disclosed. The system includes a mobile housing or mobile container that houses a polystyrene foam densifying machine. The foam densifying machine reduces the size of Expanded Polystyrene (EPS) and PS polystyrene material into a marketable product. The mobile container includes secure access doors, electrical connections, lighting, exhaust fans, and storage bins for EPS waste. The waste recycling system provides a mobile outdoor or indoor recycling facility and collection center where EPS/PS may be recycled instead of being sent to a landfill.

A method for the reduction and/or removal of pathogenic agents and microorganisms contained in solids, comprising the steps of purification of the starting material to dispose of materials that combine a great size and extreme hardness and malleability; and the adjustment of the humidity degree of the material obtained in step of purification, and the grinding and heating of the material obtained in the step of adjuisting the humidity, where the grinding and heating are carried out simultaneously by subjecting the material to a high pressure while at the same time its temperature is increased by means of an increase in the pressure on the material and the friction caused between the material and the grinding means. And A machine to carry out the method, comprising a front chamber for the entrance of the material; a contiguous rear chamber associated with the entrance chamber, by means of which the processed material is expelled; said contiguous rear chamber containing a grinding means that rotates when it is actuated by an engine; and a piston that enters into the front chamber running along said chamber into the rear chamber until it reaches a grinding means, where the grinding means consists of a solid, hard and heavy cylinder associated with a transverse axis, said cylinder being provided with a set of longitudinal slots from base to base that form edges with the cylinder surface.

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 mill includes a generally vertical, rotatable shaft having at least one set of cutter blades driven thereby and a fan assembly mounted on the shaft below the cutter blades in position to receive output therefrom. The fan assembly includes a fan disc secured to the shaft and rotatable therewith. A plurality of fan blades is secured to the fan disc in a generally radial orientation. A terminal portion of the mill includes a gradually, radially expanding outer wall configured in a volute form. The expanded outer wall decreases wear and increases efficiency of discharge and airflow through the mill.
