That's a great and practical question! The weight of an empty outdoor trash bin isn't a single number, as it depends heavily on the bin's material, size, and purpose. Generally, a standard empty 35-gallon plastic curbside bin, common for residential use, weighs between 15 to 25 pounds (7 to 11 kg). These are made from durable, molded polyethylene and are designed to be light enough for most adults to wheel to the curb.
For larger 65-gallon or 95-gallon wheeled carts, the empty weight can range from 30 to 50 pounds (14 to 23 kg). Commercial bins are a different story. A standard empty 2-yard metal dumpster can weigh 200 to 300 pounds (90 to 136 kg), while larger 6-yard models can be over 500 pounds (227 kg) empty, due to their heavy-gauge steel construction.
In summary, always consider the bin's capacity (gallons or yards) and material (plastic, metal, resin) when estimating its empty weight. For specific handling or shipping needs, checking the manufacturer's specifications is always the best practice.
