That's a great question! Finding an outdoor trash can that's easy for one person to move is all about balancing weight, durability, and design. For the absolute lightest option, you'll want to look at resin or plastic models. These are significantly lighter than metal or stone alternatives.
Many brands offer lightweight bins in the 10-20 gallon range, which is ideal for manageable weight when full. Key features to look for include integrated handles or hand grips, and models with two wheels (like a dolly) rather than just a bottom slider. A wheeled bin, even if slightly heavier empty, becomes the easiest to maneuver when loaded.
While specific model names change, searching for "lightweight outdoor roller bin" or "portable patio trash can" will point you in the right direction. Always check the product's empty weight in the specifications. For the ultimate in portability, consider a small, handled bin you can carry or a two-wheeled model you can easily tilt and roll, making taking the trash out a one-person breeze.
