Construction and demolition waste
From Wikipedia, the free encyclopedia
Construction and demolition waste (C&D waste) includes all waste material incidental to the construction/building or demolition industries. [1]. As well as waste building materials,it can include dredging materials, tree stumps, and rubble including pavements. C&D waste may contain lead, asbestos, or other hazardous substances[2].
Certain components of C&D waste such as plasterboard are hazardous once landfilled. Plasterboard is broken down in landfill conditions releasing hydrogen sulfide, a toxic gas.
There is the potential to recycle many elements of C&D waste. Rubble can be crushed and reused in construction projects. Waste wood can also be recovered and recycled.
Government or local authorities often make rules about how much waste should be sorted before it is hauled away to landfills or other waste treatment facilities. Some hazardous materials may not be moved, or demolition begun, before the authorities have ascertained that safety guidelines and restrictions have been followed. Among their concerns would be the proper handling and disposal of such toxic elements as lead, asbestos or radioactive materials.
