Herein described is a bin for collecting solid waste, in particular urban waste, provided with a device for weighing the products deposited by a single user, of the type made up of two containers, the outer covering one and the inner one for collecting waste. Such bin includes a rigid frame arranged in the gap between the two containers. Such frame rests on four stanchions on the bottom of the more outer container, where the wheels are applied, whereas on the upper edge some load cells are arranged, which support the most inner container so as to be able to detect the weight of the waste deposited in the bin by the user.
