That's an excellent and very relevant question, especially in today's world. A focus on hygiene is more important than ever, and thankfully, yes, there are several types of outdoor trash bins designed specifically for hands-free operation to minimize contact.
The most common and reliable type is the pedal-operated bin. These feature a foot pedal that you press to lift the lid, keeping your hands completely free from the bin's surface. They are durable, don't require power, and are a staple in many parks, outside restaurants, and residential areas.
For a higher-tech solution, some outdoor spaces are installing sensor-activated (automatic) bins. These use an infrared sensor to open the lid when it detects motion. They offer the ultimate touch-free experience but require batteries or power and can be more expensive.
Another clever design is the step-can, where you step on a lever at the base to tip open a lid at the top. There are also crank-handle bins you operate with a turn of a wrist, avoiding direct contact with the main lid.
When looking for one, consider durability (stainless steel or heavy-duty plastic), a secure lid to keep pests out, and ease of cleaning. For public hygiene, these bins are a fantastic step forward, allowing everyone to dispose of waste safely and cleanly.
