In North America, a roll-off is a usually open top dumpster characterized by a rectangular footprint, utilizing wheels to facilitate rolling the dumpster in place. The container is designed to be transported by special roll-off trucks. Roll-offs are commonly used to contain loads of construction and demolition waste or other waste types. While most roll-off containers have a swinging door on the end for easier disposal of waste, some roll-off containers are not open top and are used with commercial or industrial trash compactors.
Construction debris may originate from a building site where something is being built, renovated, or demolished. Roll-off dumpsters are also used for various jobs that need much material to be taken away. The material in the roll-off may be taken to a landfill, recycled or disposed/recovered of in some other way.
