ABSTRACT

Construction and demolition (C&D) debris is generated when new structures are built and existing structures are renovated or demolished (Figure 21.1). Structures include residential and nonresidential buildings and public works projects such as streets, highways, bridges, and piers. Components of C&D debris include concrete, asphalt, wood, metals, gypsum wallboard, and roofing. State definitions of C&D debris may also be expanded to include trees, stumps, soil, and rock from clearing construction sites.
