That's a great question that doesn't have a single, simple answer, as it depends heavily on the bin's size, material, and design. However, I can give you a solid range based on common specifications.
A typical commercial-grade urban trash bin, often called a dumpster or a wheeled cart, is usually made from heavy-duty polyethylene plastic or, more commonly for larger units, galvanized steel. The empty weight is primarily about the material and structural integrity needed to handle heavy loads and rough use.
For the standard 2 to 4 cubic yard steel dumpster you see behind restaurants and apartment buildings, the empty weight typically falls between 250 to 400 pounds (115 to 180 kg). Larger 6 to 8 cubic yard containers can easily weigh 500 to 800 pounds (225 to 365 kg) empty. Smaller commercial wheeled carts (around 1 cubic yard) are lighter, often in the 60 to 100 pound (27 to 45 kg) range.
The steel's gauge (thickness), the reinforcement on the corners and lid, and the axle assembly for wheeled units all add significant mass. So, while the contents are the main challenge, moving an empty commercial bin still requires proper equipment and handling due to its substantial inherent weight.
