Construction waste consists of unwanted material produced directly or incidentally by the construction or industries. This includes building materials such as insulation, nails, electrical wiring, shingle, and roofing as well as waste originating from site preparation such as dredging materials, tree stumps, and rubble. Construction waste may contain lead, asbestos, or other hazardous substances.
Much building waste is made up of materials such as bricks, concrete and wood damaged or unused for various reasons during construction. Observational research has shown that this can be as high as 10 to 15% of the materials that go into a building, a much higher percentage than the 2.5-5% usually assumed by quantity surveyors and the construction industry. Since considerable variability exists between construction sites, there is much opportunity for reducing this waste.
There is the potential to recycle many elements of construction waste. Often roll-off containers are used to transport the waste. Rubble can be crushed and reused in construction projects. Waste wood can also be recovered and recycled.
In England, all personnel performing builders or construction waste clearance are required by law to be working for a CIS registered business.

The traditional disposal way for construction waste is sent it to landfill sites. By directly landfill those waste, it will cause many problems in the long period:
- Waste natural resources
- Increase the construction cost, especially the transportation process
- Occupy a large area of land
- Reduce soil quality
- cause water pollution
- cause air pollution
- produce other security risks et.
