Construction and demolition debris, also known as C&D, includes; asphalt, concrete (with or without rebar), lumber, drywall and other building materials. Waste generated during C&D activities can also include large quantities of material found in the general waste stream. For example, corrugated cardboard from packaging, a variety of plastics (PVC pipe, packaging, etc.), glass, yard wastes from site work and clearing, and even plastic bottles and aluminum cans are commonly produced on job sites.
Most C&D materials can be reused or recycled into new construction materials or other beneficial uses. For example, aggregate (produced by crushing concrete or asphalt) is widely recyclable. Recycled aggregate can be used for many purposes; the primary market is road base.
C&D materials are heavy, not easily compacted, and take up space in the landfill. That’s why it’s important to separate and recycle or divert these materials from the landfill. Keeping different types of building materials separated will result in significantly lower fees and charges and save some money on your next project.

Several local Salinas Valley jurisdictions have adopted C&D ordinances as an effective method for diverting this material from the landfill. While ordinance requirements may vary slightly the main objective is to require contractors to deconstruct, reuse, salvage, recycle and/or divert C&D materials from construction projects and document those efforts.

In addition, the California Green Building Standards or CalGreen Code requires the diversion of at least 65% of the construction waste generated during most “new construction” projects. Subsequent amendments have expanded upon what types of construction are covered; see the updated code that was effective Jan 1, 2017.
