It depends if you are near your listing or a remote Host. If near your listing, then many Hosts just take care of it themselves as @Shelley159 . If not, then remote Hosts either pay their cleaners extra to come back to the listing on trash day and take the bins to the street and return them after trash pickup, (most cleaners will charge extra to do this), or pay someone as @Mike-And-Jane0 said to do it.
If the guest is staying at the property on trash pickup day, we usually message them and ask if they would please take the trash to the curb for pickup. This is added to our House Manual and Addl House Rules on the listing. Most guests are perfectly fine with that, as it gets the trash out of the house and gives them an empty bin to use afterwards when they check-out. We have never had a guest refuse to do this if they happen to be staying on trash pickup day. However, I guess they could refuse; its possible. Then you should have a backup plan as previously discussed to handle the trash.
