That's an excellent and very practical question! It's a common frustration for municipalities, businesses, and property managers. The good news is, yes, there are definitely outdoor trash bins designed with special surfaces to combat stickers and adhesive graffiti.
The most common solution is a type of non-porous, smooth coating or laminate applied to the bin's exterior. Often called "anti-graffiti" or "anti-adhesive" coatings, they create a surface that doesn't allow adhesives to bond strongly. When someone tries to stick a poster or sticker on it, the adhesive doesn't penetrate the surface. This means the sticker can often be removed much more easily—sometimes just by peeling it off by hand or with a simple plastic scraper, without leaving that horrible, gummy residue behind. Some coatings are even "sacrificial," where you remove the graffiti/sticker along with a top layer of the coating and then reapply a fresh coat.
You'll typically find these features on higher-end, durable public litter bins made from materials like powder-coated steel, stainless steel, or heavy-duty polymer plastics. Brands that specialize in municipal or commercial site furnishings often offer this as an option. It's a bit of an investment upfront but can save significant time and money on maintenance in the long run.
When searching for them, look for product descriptions that mention "graffiti-resistant," "easy-clean surface," "anti-adhesive," or "vandal-resistant" properties. It's always a good idea to contact the supplier directly to ask about the specific coating technology and its proven effectiveness against stickers. While not 100% magical, these bins are a huge step forward in keeping public spaces looking clean with less effort.
