A recycling appliance is for processing non-organic recyclable materials and organic materials. The recycling appliance includes a non-organic processing assembly configured to receive, process and store the non-organic recyclable materials. An organic processing assembly is spaced apart from the non-organic processing assembly. The organic processing assembly is configured to receive, process and store the organic materials. A housing assembly is configured to house the non-organic processing assembly and the organic processing assembly.

A black tank arrangement is provided having a selectively operable macerator for recirculating fluid adjacent the black tank outlet back toward the black tank inlet, so as to flush or spray waste from that inlet toward the outlet. Selecting the fluid transfer components to be mountable adjacent the end face of the black tank near the black tank outlet allows the invention to be retrofit into previously installed black tanks in vehicles. Operation of the macerator can be manual, via a remote switch held down by the user for a given time period, and/or automatic, in sequence with toilet operation.

The present invention comprises a method of shredding treated medical waste, cleaning it of all traces of biological gunk, and sorting it into separate components for recycling. To clean biological gunk from materials, all materials must be first shredded into small parts to expose the interior. The cleaning is performed by submerging the gunk coated materials into a caustic solution that breaks down and dissolves the gunk off of the materials. The caustic solution may comprise sodium hydroxide, potassium hydroxide, or a similar chemical, which is highly effective in producing a corrosive chemical that can break down blood, bone marrow, urine, unused medication, food waste, organs, tissues and any other biologic materials. After all of the biological material is removed from the cleaned materials, they are sorted into component materials, such as plastics, metals, rubbers, glass, etc.

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 paper shredder includes a housing, cutters positioned in the housing, and a feeder base adapted to support a stack of paper. The feeder base includes a feeder slot. The feeder base is integrally-formed as one piece having a front portion, a rear portion, and a sidewall along first and second sides and spanning the feeder slot.

A size reduction device and method for solid particles, which are conveyed as a suspension in a liquid flow. The device includes a housing, at least two counter-rotatable size reduction components disposed in the housing, each including a plurality of cutting elements, disposed on a common rotatable shaft with a longitudinal axis. The flow direction of the suspension is at right angles to the longitudinal axes of the shafts of the size reduction components. Two mutually opposite guide rails with a longitudinal axis parallel to the shafts are assigned to components. Each guide rail includes a base plate, on which ribs with channels are constituted parallel to the flow direction on the side of the base plate towards the component.

Systems and methods for rendering cannabis-related waste materials are provided. The method may include inserting a plurality of cannabis-related waste materials into, for example, a mobile rendering vehicle. The method may further include physically altering the cannabis-related waste materials such that the cannabis-related waste materials are unrecognizable and unusable. The insertion of the cannabis-related waste materials into the mobile rendering vehicle may be recorded and/or the physical alteration (e.g., pulverization) of the cannabis-related waste materials may be recorded via one or more cameras disposed on the mobile rendering vehicle to verify proper insertion and/or alteration of the cannabis-related waste materials.

A shredding device for shredding materials is provided, the shredding device having: a housing, a rotor in the housing, a pusher element which is pivotable about an axis, so that it pushes the material to be shredded towards the rotor, and a service hatch which is mounted on the housing and configured in such a manner that in an open state it exposes a first opening in the housing with access to a rotor and a second opening in the housing with access to the underside of the pusher element when the latter is pivoted upwardly.

A cutter assembly configured for a grinder pump and including a cutter wheel and a cutter disc that interact with each other. The cutter wheel includes a shaft portion that is configured to interact with a central hole of the cutter disc, a hub portion that is connected to the shaft portion and at least two main cutting edges that in the radial direction extend outwards from the hub portion and that are configured to interact with a set of cutting holes of the cutter disc. The shaft portion includes an axially extending cutting recess. The hub portion includes only one radially extending cutting recess. The cutter disc includes a suction side, a central hole that is configured to interact with the shaft portion of the cutter wheel and a set of cutting holes that open in the suction side radially outside the central hole.

A comminution device comprises a plurality of first cutting elements having first serrated cutting edges disposed on a first circular path; a second cutting element having a second serrated cutting edge corresponding to the first serrated cutting edges for cutting through cutting material, the second cutting element being displaceable about an axis of rotation on a second circular path concentric with the first circular path. The second serrated cutting edge comprises a plurality of jags and each jag comprises a radially inner flank and a radially outer flank, each at an angle to the axis of rotation. A drive rotationally drives the second cutting element about the axis of rotation and an adjustment mechanism by which the plurality of first cutting elements and the second cutting element are displaceable relative to each other axially in the direction of the axis of rotation, that a cutting gap between them is adjustable.
