That's a great question, and yes, they absolutely do! You've probably seen them without even realizing it. Many cities, especially in areas with high foot traffic like outside office buildings, in parks, or near public transit stops, install trash receptacles that have a small, often metallic, tray or cylinder built right into the top or on the side. These are specifically designed for cigarette disposal.
The main idea behind these bins is to tackle the issue of cigarette butt litter. By providing a safe and convenient place to extinguish and discard cigarettes, cities hope to keep sidewalks cleaner and reduce fire risks. The ashtray component is usually separate from the main trash compartment to prevent potential fires from smoldering butts mixing with other waste.
So next time you're walking around, take a closer look at the public bins. You'll likely spot these integrated ashtrays, a small but important feature in urban design aimed at promoting cleaner and safer shared spaces.
