Yes, they do. Urban trash bins with automatic sensors are already used in many cities, airports, campuses, and busy public spaces. Most of them use motion or proximity sensors, so when you move your hand or step near the bin, the lid opens by itself. Some models also use foot sensors or touchless buttons to keep things more hygienic.
These bins are often called smart waste bins or touchless bins. The basic idea is simple: a sensor detects movement, sends a signal to a small motor, and the lid opens for a few seconds before closing again. Some advanced versions are solar-powered and can compact trash, which means they hold more waste and need to be emptied less often. Cities also use them because they can send alerts when a bin is full.
That said, they are not everywhere yet. Automatic sensor bins cost more than standard bins, and they need maintenance, batteries, or power. In very busy areas, the sensor mechanism can also get dirty or damaged. But for busy streets, parks, transit stations, and public plazas, they can be a practical upgrade.
So if you are asking whether automatic sensor trash bins exist in urban settings, the answer is a clear yes. They are part of a wider trend toward cleaner, more touchless, and more connected public infrastructure.
