If you live in a city that gets scorching hot during the summer, you've probably noticed that plastic items left outside can sometimes soften, bend, or lose their shape. Your outdoor trash can is no exception. So, to answer your question directly: Yes, the plastic on an outdoor trash can can absolutely warp under intense and prolonged heat.
Why does this happen? Most standard trash cans are made from plastics like polyethylene. While durable, these materials have a melting point. Even if the air temperature is only 90°F (32°C), the sun's radiant heat can cause the surface of a dark-colored plastic bin to reach temperatures of 150°F (65°C) or more. At these high temperatures, the plastic polymer chains become more flexible and can sag under their own weight or the weight of the trash inside, leading to permanent warping.
However, not all plastics are created equal. Higher-quality trash cans are often made from high-density polyethylene (HDPE) or are labeled as "UV-resistant." These are much more resilient to heat and sunlight, but even they have their limits during a relentless heatwave.
So, what can you do to protect your bin?
* Seek Shade: The simplest solution is to move your trash can to a shaded area, even if it's just for the hottest part of the day.
* Choose Lighter Colors: If buying a new can, opt for white or light beige. These colors reflect sunlight instead of absorbing it, keeping the plastic cooler.
* Check the Plastic Type: Look for bins made from HDPE or those specifically marketed for all-weather or UV-resistant use.
* Avoid Overfilling: An overstuffed bin is heavier, putting more strain on the plastic walls when they are softened by heat.
In short, plastic trash can warping in a hot city is a common issue, but it's largely preventable. By understanding the cause and taking a few simple proactive steps, you can extend the life of your outdoor bin significantly.
