Waste stream separation as performed at the bin in Greenacre

An occupier can install three-stream bins in every room and label them perfectly, and it all becomes irrelevant if the cleaner arrives with one large bag. That happens more often than most clients realise, usually because the trolley was set up for a simpler site and nobody revisited it. The fix is a trolley configured with the number of streams the building actually uses, which is a physical change rather than an instruction.

It also has to be practical to work. A trolley carrying four bags through a narrow corridor is unusable, and a cleaner will consolidate to get through the shift. So the arrangement is designed with the route in mind: staged collection points, a second run for a low-volume stream, or bagging at a central point on each floor. Design solves this where instruction does not.

The bin store routine matters as much as the collection. Bags go into the correct bin, lids are closed, the floor is left clear and the store is left in a condition the next person can work in. Where bins are full, the overflow is not placed beside them but reported, because a bin store with bags on the floor attracts vermin and rapidly becomes a place nobody wants to enter.

Collection days change what is possible. A store emptied on a Monday morning has capacity on Monday night and none by Thursday. The crew works to that rhythm, which means knowing the collection schedule rather than discovering the constraint each week. Where capacity is genuinely insufficient, that is a service issue for the building rather than something the cleaning crew can absorb. Working with the collection rhythm is most of what makes a bin store manageable.

Some contamination is unavoidable and the crew deals with it. Persistent contamination is different: a recycling bin in one area that always contains food waste, a paper stream that always has packaging film in it. Sorting that by hand every night is neither safe nor sustainable, and it hides a problem the occupier could fix with signage or a conversation with a particular team. It also creates a health risk for the person doing the sorting, which is reason enough on its own.

So it is reported with the location and the pattern rather than quietly corrected. That gives the client something to act on and stops the cleaning crew becoming the permanent workaround for a behaviour nobody has been told about. Where contamination makes a stream unusable, the crew treats the affected bag as general waste and records that it did so. Recording the substitution keeps the client's own reporting honest as well.
