That's an excellent question, and if you live in a hot, sunny area, it's a very common concern. The short answer is yes, over time, the plastic on an outdoor trash can is highly likely to both warp and fade. Here’s a breakdown of why this happens and what you can do about it.
Why Plastic Trash Cans Suffer in the Heat
Most outdoor trash cans are made from polyethylene or polypropylene. While these plastics are durable, they are not immune to the elements. The primary culprit is the sun's ultraviolet (UV) radiation. This constant exposure breaks down the chemical bonds in the plastic and the pigments used for color, leading to that chalky, faded appearance you often see on older bins.
The heat itself is the other major factor. On a scorching day, the surface of a dark-colored trash can can get significantly hotter than the air temperature. Plastic becomes more pliable when hot. When one side is in the sun (expanding) and the other is in the shade, or when the bin is full of heavy waste, this can cause the plastic to sag, distort, and permanently warp.
How to Protect Your Outdoor Trash Can
You can't change the climate, but you can take steps to significantly extend the life of your bin:
1. Choose the Right Can: Look for trash cans labeled as "UV-resistant" or "weatherproof." Darker colors like black or dark green absorb more heat but may hide fading better, while lighter colors like beige or light gray reflect heat but can show dirt and staining more easily.
2. Strategic Placement: This is the easiest and most effective tactic. Place your trash can in a shaded area whenever possible. Under a tree, against a shaded wall, or under a patio eave can make a world of difference.
3. Use a Protective Cover: If shade isn't an option, consider a simple protective cover or even a specially designed trash can shelter to shield it from direct sunlight.
4. Don't Overfill: Avoid overstuffing the can, especially on hot days. The pressure from the contents combined with the softened plastic is a recipe for warping.
While no plastic bin is completely immune to a harsh, hot climate, choosing a quality product and giving it a little protection from the relentless sun can keep it looking better and functioning properly for years longer.
