Embassy's under siege have an immediate need to destroy electronic devices. An electronic shredder is provided. A hand crank as backup. This invention relates to a portable electronic shredder. Further, shredder relates to the shredding of electronic devices to a very small size so as to make the shredded remnants untraceable, wherein the mobiles and laptops, CPUs and monitors can be placed for disposing of, following which the electronic devices are exposed to a pulverizer. The pulverizer crushes and cuts the electronic devices to minute remnants. The portable shredder is lightweight, compact and portable, thus making it easy to transport to an e-waste stacked place.

A food recycler includes a case, a control system within the case, and a set of user interface components that are usable to at least cause the control system to initiate a food recycling cycle. The food recycler also includes a motor within the case and a bucket that has a volumetric capacity between 2.51 and 10 liters. A filter system configured to accommodate air filters is also included in the case of the food recycler. To remove water from waste food items, the food recycler includes a drying component.

A shredder includes a shredder box having first and second opposite end walls, and first and second opposite side walls that extend between the first and second end walls. The shredder further includes a shredder rotor positioned within an interior of the shredder box, an access door that is pivotally moveable, and a control system for monitoring various parameters to operate the shredder. A side access region is defined between the first and second end walls when the access door is in the open position. The side access region provides access to the shredder rotor and includes an open region defined between the first and second end walls at the second side of the shredder. The open region has an open top which is free of obstructions extending between the first and second end walls.

A control unit for a food waste disposer has a controller that determines operational status of the food waste disposer based on motor loading of an induction motor of the food waste disposer.

A device for comminuting media materials that store sensitive information. The device is a rotating mill core with removable flat edged blades, a set of stacked bed knives and a screen. The mill core rotates in close proximity to adjustable bed knives to shear the material being fed before passing through a screen in order to grate the material. The mill core has an angular positioned blade constructed and arranged to shear material with said bed knives. The mill core has a mass and is operated at 1000 rpm. A flywheel is further attached to the mill core in order to conserve rotational energy and improve the efficiency of the device. Vacuum ports facilitate cleanup.
