Placing a bench near a garbage can is a practical use of space, but it raises a valid concern: odor. The good news is, yes, several materials are highly resistant to absorbing and retaining unpleasant smells, making them ideal for such locations. The key is selecting non-porous, easy-to-clean surfaces.
First, consider metals like aluminum and powder-coated steel. These are inherently non-porous, meaning odors cannot seep into the material. A smooth powder-coated finish provides an extra barrier and allows for quick wiping with a mild disinfectant. They are durable, weather-resistant, and highly practical.
Another excellent choice is concrete or synthetic stone. While porous in its natural state, a high-quality sealant creates an impermeable surface that blocks odor absorption. Modern precast concrete benches often have this sealant integrated. Their solid, sturdy nature also simplifies rinsing with a hose.
For the seating slats, High-Density Polyethylene (HDPE) lumber is a top performer. Made from recycled plastics, it is completely non-porous, immune to rot, and won't absorb liquids or smells. A simple wash removes any residue. It's a low-maintenance and eco-friendly option.
Avoid natural, unsealed wood (like cedar or pine) and porous composites in these areas, as they can trap odors and bacteria. The best practice is to pair a durable, odor-resistant frame material with HDPE or metal slats. Regular, basic cleaning is still recommended to maintain hygiene and appearance, but with the right materials, your bench will remain a fresh and functional seating solution for years.
