That's a great question, and one I hear often from smokers looking to be responsible. Yes, you can definitely find public waste bins with built-in ashtrays on top, though their availability really depends on your location.
In many cities, especially in downtown areas, parks, and outside public buildings, these combination bins are quite common. The design is smart: a sturdy metal or plastic top with one or more recessed trays filled with sand or a non-flammable material for extinguishing cigarettes. This helps keep the main bin from catching fire and encourages people to dispose of their butts properly instead of littering.
You'll often spot them near benches, transit stops, and building entrances. Their purpose is dual: to manage general litter and to specifically contain cigarette waste, which makes street cleaning easier and reduces fire risk. If you're having trouble finding one, check designated smoking areas or look for bins that have a distinct, often cylindrical or hooded, top section.
While not every single trash can has this feature, municipalities are increasingly installing them as part of cleaner city initiatives. So next time you're out, take a closer look at the public bins—chances are, many will have that helpful ashtray right on top.
