Absorbing it quietly is the most expensive option
When a cleaner removes dumped material as part of a routine visit, the scheme pays for it twice over. It pays in labour that was budgeted for something else, and it pays in losing the only record that would show how often it happens. A committee reviewing the budget a year later sees a service that seems to cost more than it should, with no explanation available to anyone.
Handling it as a separate item changes both. The routine attendance stays predictable and comparable year to year, and each removal appears with a date attached. That gives the committee something to work with when deciding whether the answer is better lighting, a locked enclosure, a different collection arrangement or a conversation with a particular occupier. None of those options is available to a committee working from an impression.
