That's a great question, and one I've actually noticed more in cities lately. Yes, you can definitely find urban trash cans with built-in ashtrays on top. They are becoming a more common sight in many downtown areas, outside office buildings, near public transport stops, and in entertainment districts.
These specialized bins are designed to tackle a specific litter problem: cigarette butts. The typical design features a standard waste opening for general trash, with one or more dedicated metal or heat-resistant receptacles on the top or sides specifically for extinguishing and disposing of cigarettes. Sometimes the ashtray part is a simple sand-filled tray, while other models have a cylindrical stubber plate with a hole.
The main idea is to provide a convenient and safe option for smokers, encouraging them to dispose of their butts properly instead of tossing them on the ground. This helps keep sidewalks cleaner, reduces fire risks from hot embers, and makes the job easier for street cleaners. While not every single public bin has this feature, they are a key part of many modern city waste management and anti-litter strategies. So next time you're walking in a city center, take a look at the trash cans—you might spot one of these handy combo units.
