It really depends on the type of bin. For most urban household and small-business collection, the common wheeled bins are 120L, 240L, and 360L. A 120L bin is usually around 8–12 kg empty, a 240L bin around 10–20 kg, and a 360L bin around 15–25 kg. Once they are loaded, the weight changes a lot: a normal 120L bin might be 30–50 kg, a 240L bin 50–80 kg, and a 360L bin 80–120 kg or more if the waste is dense. Public street litter bins can be heavier and may be fixed in place, while large commercial dumpsters are in a different category and usually need a truck.
So, can one person move them for collection? Usually, yes—for a normal wheeled bin on flat, paved ground. A collection worker or resident can roll a 120–360L bin short distances if the wheels are working, the load is balanced, and the path is clear. But that does not mean one person should lift it. Most bins are designed to be rolled to the truck, then emptied mechanically. If a bin is overloaded, has broken wheels, is on a slope, or must go up steps or over a high curb, one person should not force it. In those cases, use two people or ask for a special collection. A good rule: if it will not roll smoothly, it is too heavy or unsafe for one-person handling.
