Although the building stock varies physically in many ways, sometimes including ground-floor commercial spaces, residential waste management within buildings can be categorized into four typologies.
typology 1
Central Location
In the simplest scenario, residents bring waste to a central waste area. The area may be interior (at grade level or in the cellar) or exterior (in front of the building within the property line, on the sidewalk or in a side yard).
Moving bins to the exterior can remove odors and pests from the interior but be detrimental to the quality of the sidewalk experience.
Typically used with wheeled bins and no compaction and Central storage in cellar and on street.

typology 2
Service Corridor
these are large apartment buildings, often cooperatives, with doormen and staff who service the building through its separate service circulation. Residents generally place their waste in bins or bags, as well as bundled cardboard, directly outside the service door to their apartment.
Waste left by residents outside of the apartment service door
typology 3
Corridor Chute
Typically found in larger apartment complexes, this system often consists of a narrow chute that previously emptied into an incinerator. The chute door is in the egress corridor, or alongside the elevator.

Recycling is located in a central area.
typology 4
Trash Room With Chute and bins
Trash goes down the chute to a compactor. The trash room is often small and unventilated with just enough space for small recycling bins. There are multiple chute options: just trash chute, single chute with sorter, or MULTIPLE CHUTES.

typology 5
single chute with sorter
Sorter systems allow use of a single chute for multiple waste streams. Before opening the chute door, residents press a button to choose the waste stream. The sorting equipment directs the trash into a compactor and the recycling streams into containers.

typology 6
multiple Chutes
Multiple chutes allow for co-located disposal of multiple waste streams without mechanized sorting systems. Typically residents enter a trash room with three chutes: one leading to a compactor, one for MGP and another for paper. Cardboard must be left in the trash room or taken to a central location.
Three separate chute doors for trash, MGP and paper; Trash chute empties into a compactor; MGP and paper chutes empty into tilt trucks
