That's a great question! I've noticed the same thing, and it really comes down to your specific situation. Both metal and plastic outdoor trash bins have their pros and cons, so let's break it down.
Metal bins, often made from galvanized steel, are known for their durability and sturdy feel. They're heavy, which makes them harder to knock over in windy areas, and they can handle rough handling without cracking. However, they're prone to rust over time, especially if the coating gets scratched, and they can be noisier when emptying. They also tend to be more expensive upfront.
On the other hand, plastic bins are lightweight, making them easy to move around, and they're immune to rust. They're usually more affordable and come in various colors. But they can fade in the sun, become brittle in extreme cold, and might crack under impact. They're also easier for animals to tip over.
In terms of the environment, metal is often recyclable, but plastic can be too, depending on the type. For high-traffic areas or places with harsh weather, metal might last longer, while plastic could be better for casual home use where cost and portability matter. Ultimately, it's about weighing factors like durability, cost, and maintenance to pick what fits your lifestyle best!
