C&D Debris

Construction and Demolition (C&D) Debris: C&D debris results from construction, remodeling, repair or demolition of buildings, roads or other structures. It includes (but is not limited to) wood, concrete, drywall, masonry, roofing, siding, structural metal, wire, insulation, asphalt, packaging materials related to construction or demolition.

ADC (Alternative Daily Cover): Cover material other than earthen material which is placed on the surface of the active face of a municipal solid waste landfill at the end of each operating day to control vectors, fires, odors, blowing litter, and scavenging.

Appropriate for Processing: Loads of C&D materials entering a facility of which most of the material (˜90%), as determined by the processor, can be sent on by the facility for recycling. Usually charged a lower rate.

Beneficial Use: The use of C&D waste as an ingredient in a manufacturing process, or as an effective substitute for natural or commercial products in a manner that does not constitute recycling and in a manner consistent with all applicable laws. Beneficial Use includes but is not limited to use as hog fuel and alternate daily cover.

Commingled C&D: Pure loads of Recyclable C&D Waste that contain mixed types of recyclable materials stored in one on-site container, which is taken to a sorting facility where materials are separated for recycling. Non-recyclable material may no be placed in a commingled container.

Hog Fuel: A specific grade of ground up wood and bark. It varies in size but is generally between ½" and 6" screen size. In the Pacific Northwest, hog fuel from C&D recycling facilities is generally used to fuel boilers for the wood and paper processing or other industries.

Inappropriate for Processing: Loads of C&D materials entering a facility of which less than 90%, as determined by the processor, can be sent on by the facility for recycling. Usually charged a higher rate.

IWS (Industrial Waste Stabilizer): Material which is mixed with industrial ash to structurally stabilize the ash.

Mixed C&D Waste: C&D materials containing both recyclable and non-recyclable C&D materials that have not been source separated. C&D waste is considered to be mixed C&D waste if it contains more than 10 percent but less than 90 percent recyclable C&D waste by volume.

Pure Loads of Recyclable C&D Waste: Loads of single or mixed types of recyclable C&D waste that contain at least 90 percent recyclable C&D waste materials by volume.

Recyclable C&D Waste: C&D waste that can be diverted from C&D waste and reused, recovered or re-manufactured into a reusable product or put to a beneficial use. Recyclable C&D waste may consist of a single type of recyclable material or a mixture of two or more types of recyclable materials.

Source-separated C&D Waste: A single kind of recyclable C&D waste material that has been separated from other C&D waste materials at the site of remodeling, repair, construction, demolition, or land clearing before it is transported to a receiving facility.

Total Inbound Tons: The total tons of recyclable C&D waste, mixed C&D waste and non-recyclable C&D waste entering a receiving facility.
