What Are C&D Materials?

Construction and demolition (C&D) materials are generated when new building and civil-engineering structures are built and when existing buildings and civil-engineering structures are renovated or demolished (including deconstruction activities). Civil-engineering structures include public works projects, such as streets and highways, bridges, utility plants, piers, and dams.

C&D materials often contain bulky, heavy materials such as:

• Concrete
• Wood (from buildings)
• Asphalt (from roads and roofing shingles)
• Gypsum (the main component of drywall)
• Metals
• Bricks
• Glass
• Plastics
• Salvaged building components (doors, windows, and plumbing fixtures)
• Trees, stumps, earth, and rock from clearing sites
