The bin store is a shared constraint, not a detail
In a mixed building the waste store is used by tenants who generate very different volumes. A food business below can fill a shared store well before collection day, which leaves an upstairs office with nowhere to put its own waste through no fault of its own. That is a scheduling problem as much as a building management one.
Knowing the collection days changes what can be done about it. If the store is emptied on a Tuesday and a Friday, the office waste run is far better placed on those evenings than on a Monday, when the store is at its fullest. It is a simple adjustment and it removes a recurring frustration without needing anyone else's cooperation.
