An organic waste treatment method according to the present disclosure is an organic waste treatment method of performing methane fermentation of a mixture of poultry manure and food waste, in which the mixture contains the food waste at a ratio of 5% or more. With the organic waste treatment method, it is possible to stably perform the methane fermentation of the organic waste at low cost.

A hydrolyzer outfeed system includes a hydrolyzer having a hydrolyzer outlet, an intermediate pressure chamber having a pressure chamber inlet and a pressure chamber outlet, and an expansion chamber. A pressure chamber inlet valve selectively communicates the hydrolyzer outlet with the pressure chamber inlet, the inlet valve having an inlet valve cross-sectional area in a fully open position. A pressure chamber outlet valve selectively communicates the pressure chamber outlet with the expansion chamber. The pressure chamber outlet valve has an outlet valve cross-sectional area in a fully open position. The outlet valve cross-sectional area is smaller than the inlet valve cross-sectional area.

Provided herein are methods for degrading a combination of food stuffs and non-biodegradable food packaging, the method comprising: obtaining a combination of the food stuffs and non-biodegradable food packaging; contacting the combination of food stuffs and non-biodegradable food packaging with a superworm or mealworm; and incubating the combination of food stuffs and non-biodegradable food packaging and the superworm or mealworm under conditions in which the superworm or mealworm degrades both the food stuffs and non-biodegradable food packaging.

An organic waste processing device comprising: an organic matter-receiving container defining an organic matter-receiving chamber; a gas-propelling unit; a gas-plenum chamber in gas communication with the gas-propelling unit; and a grinding assembly at least partially contained in the organic matter-receiving chamber. The grinding assembly comprises a drive shaft and a rotatable blade assembly including a blade support sleeve mounted to the drive shaft and being engaged in rotation therewith. The rotatable blade assembly further includes at least one blade mounted to the blade support sleeve. An inner surface of the blade support sleeve is spaced-apart from an outer peripheral surface of the drive shaft to define a gas flow channel extending longitudinally into the griding assembly and providing gas communication between the gas-plenum chamber and the organic matter-receiving chamber.

A food waste disposer with an air exhaust duct capable of being disassembled, assembled and cleaned conveniently comprises a main casing, a drying and crushing device, an exhaust deodorizing device, a coil core assembly, and a magnetic rotor. The main casing comprises a device chamber, a deodorizing chamber with a rear opening, and a detachable back cover. The exhaust deodorizing device comprises a water receiving bottom box, a ventilation device, and a deodorizing box. The ventilation device comprises a longitudinal air duct and a centrifugal wind wheel. The longitudinal air duct comprises an air suction duct, a volute, and an air exhaust duct. The air suction duct is communicated with an air guide channel. The centrifugal wind wheel and the magnetic rotor are provided on the ventilation device, and the magnetic rotor rotates with the centrifugal wind wheel. During cleaning, there is no need to worry about electrical conductivity.

A food waste processing system including an enclosure secured to prevent unauthorized access to a food waste processing system housed within the enclosure. The food waste processing system including an imaging system configured to capture a plurality of images of the food waste input stream including food waste suitable for the bio-degradable input stream and contaminant material, and a processing system configured to identify types of fruits and types of vegetables included in the food waste input stream and to automatically determine a quantity of at least one of a type of fruit and/or a type of vegetable included in the food waste input stream. The system including a port configured to deposit the food waste input stream from a location outside of the enclosure. A liquid fertilizer dispensing device configured to allow a removal of liquid fertilizer from the food waste processing system from a location outside of the enclosure.

A modular organic substance processing system comprising:a modular frame arranged to support a plurality of containers, each container housing a plurality of decomposition organisms arranged to aid in the decomposition of organic substance, wherein the modular frame includes a plurality of shelf members, each shelf member being arranged to be stackable on another shelf member to define the modular frame and further comprises a shredder unit arranged to shred the organic substance and to deposit the shredded organic substance into one of the plurality of containers.

An automated food waste processing system including an enclosure secured to prevent unauthorized access to contents contained therein, the enclosure including a plurality of exterior walls and a food waste processing system housed within the enclosure. The food waste processing system including an imaging system configured to capture a plurality of images of the food waste and the non-biodegradable material received by the sorting receptacle, a processing system configured to process the plurality of images using a trained neural network to identify at least plastic waste and metal waste as the non-biodegradable material when included in the food waste input stream as received by the sorting receptacle, and a sorting system configured to, in response to instructions received from the processing system, automatically locate and remove the non-biodegradable material from the sorting receptacle to create a bio-degradable input stream to the anaerobic digester.
