Garbage Chute

a device in high-rise buildings (mainly apartment houses) for removing garbage. The most common type is the “dry” garbage chute, which consists of a shaft with a ventilation pipe (the upper part of the shaft), loading hatches, and a receiving area (with cans or containers). The shaft, which is usually made from asbestos-cement pipes 400 mm in diameter, should be vertical and have a smooth inner surface and soundinsulating casing. The loading hatches (on the feeders of the chute) are located in stairwells or apartment kitchens. The receiving area is located beneath the chute on the ground floor or in the basement of the building; it should be at least 2.5 m high, 1.5 m wide, and 2.5 m long, to provide space for garbage cans. The possibility of connecting the chute to a vacuum-pneumatic garbage removal system is promising.
