What Is C&D Debris?
C&D debris includes concrete, wood, asphalt, steel, gypsum wallboard (drywall), brick, glass, plastics, and salvageable items from construction and demolition projects. A typical building demolition generates thousands of pounds of material that could be recovered and reused.
Recycling Rates and Opportunities
The EPA estimates that over 600 million tons of C&D debris are generated annually in the U.S. Recycling rates vary dramatically by material: concrete is recycled at over 70%, asphalt pavement at over 90% (it's one of the most recycled materials in the country), and wood, metals, and drywall at lower but improving rates.
The lowest-hanging fruit is often concrete (crushed into aggregate for road base), steel (sold to scrap yards), and asphalt (ground and reused in new pavement).
Deconstruction vs. Demolition
Traditional demolition is fast but produces mixed, hard-to-sort debris. Deconstruction — carefully disassembling a building rather than knocking it down — produces clean, reusable materials: lumber, bricks, fixtures, cabinets, appliances.
Deconstruction takes longer and costs more upfront, but the salvaged materials have real value. Habitat for Humanity ReStores buy and sell salvaged building materials. Architectural salvage companies pay for historic fixtures and materials.
For Homeowners and Contractors
If you're renovating, separate materials as you go rather than mixing everything in a dumpster. Clean wood, drywall, and metal can often be recycled separately; many C&D recyclers charge less (or pay more) for separated loads.
For large renovation projects, a 'deconstruction' approach — getting quotes from salvage companies before demolition — can offset disposal costs and reduce environmental impact.
