Construction and demolition waste
From Wikipedia, the free encyclopedia
Construction and demolition waste (C&D waste) includes all wastes arising from construction/building industries, demolition or directly, to man or the environment [1]. It can include waste building materials, dredging materials, tree stumps, and rubble resulting from construction, remodeling, repair, and demolition of homes, commercial buildings and other structures and 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 sulphide, 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.
