I don't recall seeing this mentioned before here. Visitors staying inside the walls have to beware of the rubbish collection days and for what things they can put out/when. Since the New Year there is an easy option, in via dei Bacchettoni there are now four rubbish chutes to underground bins- general waste, recycling, glass and green waste. They are very easy to use and a convenient option. They are situated at the via Elisa end, a short walk for the junction there.
