EPA estimates that 136 million tons of building-related C&D materials was generated in the United States in 1996.
- The majority of this waste comes from building demolition and renovation, and the rest comes from new construction.
- Roughly equal percentages of building-related waste are estimated to come from the residential and commercial building sectors.
- The estimated per capita generation rate for building-related debris in 1996 was 2.8 pounds per person per day.
The composition of C&D materials varies significantly, depending on the type of project from which it is being generated. For example, materials from older buildings is likely to contain plaster and lead piping, while new construction materials may contain significant amounts of drywall, laminates, and plastics. For building materials, EPA estimates the overall percentage of debris in C&D materials falls within the following ranges*:
|Concrete and mixed rubble||40-50%|
See EPA's 2009 study on building-related C&D materials for a detailed characterization of these materials:

Provides a summary of EPA's latest data on C&D debris.
Significant additional quantities of C&D materials are generated from the construction of roads and bridges, from land clearing at construction sites, and at military installations.
