Effective systems for separating, collecting and transferring organic waste from multi-unit residential buildings to deliver to composting centers are described which facilitate the reduction of contamination of the organic waste with non-compostable plastic bags. This is accomplished both by ensuring that the residents are constantly provided with compostable replacement bags for their kitchen caddies after each delivery of a bag by the resident to the recycling room, and through consistent marking that reminds residents of the system's requirements.

Waste chute devices and methods for using the same are provided. In some embodiments, a method for operating waste chutes comprises: receiving, using a hardware processor of a waste chute device, an identity associated with a user of the waste chute device; in response to receiving the identity associated with the user, allowing, using the hardware processor, a door of the waste chute device to be opened; determining, using the hardware processor, a number of items and at least one type associated with the items that have been placed in an opening of the waste chute device; determining, using the hardware processor, that the door of the waste chute device has been closed; updating, using the hardware processor, information associated with the user based on the number of items and the at least one type of items that have been placed in the opening of the waste chute device; and providing, using the hardware processor, the user with the updated information.

A two-part biowaste container for crushed biowaste includes a first part of the container for solid part of the crushed biowaste, a second part of the container for liquids separated from the crushed biowaste, which second part of the container is arranged below the first part of the container, a separating wall between the first part and the second part, a separating means arranged to the separating wall and being configured to separate at least a part of the liquids from the crushed biowaste from the first part to the second part, a drain connection in the second part for separated liquids, and a separating valve arranged to the separating wall that separates at least a part of the liquids from the crushed biowaste from the first part to the second part of the container.

A chute system for a building including: an inlet, through which an item is received; a chute, coupled to the inlet, and an outlet, coupled to the chute. The outlet includes a sealing surface, configured to form a seal with an opening of a receptacle into which the item is to be received. The sealing surface is configured to enable a seal to be formed with different receptacles having different sized or shaped openings.

A remote-controlled system and method for transporting trash comprises a carrier with wheels, a remote box having a remote transmitter and a motor, a conveyor bar attached to at least one stand, and a pair of rails. The carrier sits on the rails and moves along the rails based on its communication with the remote box. The box has a remote transmitter and a motor component that commands the carrier to move vertically down the rails at the discretion of a user. The rails are parallel to the conveyor bar and are attached to the remote box on the conveyor bar.

A diaper disposal system includes a diaper disposal container, including a container body and a slidable lid held by guide rails; a window panel; a disposal container support member with attachment points; a diaper disposal device, including an angled chute, handles, a pivotable; and a connecting chute; such that the diaper disposal device is mountable in a window opening of a building, such that an entry aperture of the diaper disposal device is exposed in an interior of the building, such that a diaper is disposable into the diaper disposal device, such that the diaper falls through the angled chute and the connecting chute, and into the diaper disposal container outside the building.

A lid assembly for use with a waste management system includes a lid having an opening defined therethrough, wherein the lid assembly is configured to couple to a container. The lid assembly also includes at least one flap assembly including a counterbalance mechanism pivotally coupled to the lid and a flap portion coupled to the counterbalance mechanism. The flap assembly is moveable between a closed position and an open position to selectively obstruct the opening.

A chute system for a building including: an inlet, through which an item is received; a chute, coupled to the inlet, and an outlet, coupled to the chute. The outlet includes a sealing surface, configured to form a seal with an opening of a receptacle into which the item is to be received. The sealing surface is configured to enable a seal to be formed with different receptacles having different sized or shaped openings.

A material handling system for the disposal of materials in multi-floor buildings. The material handling system has one or more main chutes each having one or more sets of loading stations, queue chutes, and gates. The queue chutes store material to be disposed, which is held back from entering into the main chute by the gate. The material is loaded into the queue chute via an opening in the loading station. The opening of the gates is controlled using a material handling system controller, which is controlled via a control panel or automatically using a timer or based upon the output of one or more level sensors that can determine the fullness of the queue chutes. The main chutes can have primary gates to allow for safe maintenance of the system. The loading stations can have secondary access to the main chutes.
