A garbage bin includes a bin body, a first frame, a second frame, and a lid body. The bin body has an opening and an internal space. The first frame is disposed on the bin body and includes a first engaging unit. The first frame encloses a first opening communicating the opening of the bin body. The second frame includes a second engaging unit and encloses a second opening. The second frame is detachably connected to the first frame by an engagement of the first engaging unit and the second engaging unit and communicates the first opening. Each of a direction of the second opening and a direction of the first opening is the same with the direction of the opening of the bin body. The lid body is pivotally connected to the second frame to selectively cover the second opening.

A mobile cart that holds a bag for receiving solid waste generated during a medical or surgical procedure. The cart includes a sensor that monitors whether or not an object containing metal is placed in the bag. A processor monitors the signal output by the sensor. If the sensor signal indicates that an object with a minimal amount of metal is placed in the bag, the processor momentarily asserts an audible alarm and continuously asserts a light alarm. The light alarm remains asserted until turned off. If, while the light alarm is on, the sensor signal indicates a second object with the minimal amount of waste is placed in the container, the processor again momentarily asserts the audible alarm. This provides notice that it may be necessary to investigate the contents of the bag to determine if not one but two or more objects were inadvertently discarded.

A waste or recycling container system is disclosed. The container system includes a container and a rigid liner for inserting into the container. The liner includes a supporting structure provided on a wall of the liner. The liner also includes bag retention structures. The liner is capable of being placed in the container in a first position and a second position. In the first position, the bag retention structures are below an opening of the container. In the second position, the supporting structure rests on a resting portion of the container walls and the liner is elevated with respect to the first position such that the bag retention structures are above the opening of the container.

The receptacle includes an outer body, one end of the outer body forming a base, the other end of the outer body forming a rim extending inwardly from the periphery of the outer body, and at least one inner waste containing compartment extending inwardly and downwardly from the rim. The outer body, rim and at least one inner waste containing compartment are integrally formed.

A bag (200) includes an elongated bag body (201). The elongated bag body can define two opposing ends, namely an openable end (202) and a closed end (203). An adhesive strip (308) can be disposed upon an exterior of the elongated bag body. The adhesive strip can be disposed in a horizontal orientation parallel to the openable end. A flexible strip (208) can be disposed upon the exterior of the elongated bag body. The flexible strip can be bendable to retain the openable end in an open position (601). The bag is suitable for use as a suture collection bag.

A 3 in 1 reverse vending machine. A vending machine that is solar powered and accepts bottles and cans made of plastic, aluminum, and glass. The machine includes a conveyor system, barcode reader and cleaning system, this prepares the bottle and cans to be shredded and then granulated into small pieces. The machine houses a delivery system that carries the smaller pieces of processed material to its predetermined receptacle for storage. Each bottle and can has a monetary value once received by the machine that will be issued to the user once all bottles and cans are received and calculated per user per transaction.

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.

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.
