DEEP: What is C&D ?

What is Construction and Demolition Waste?

{Red Roll-Off} Construction and demolition (C&D) waste is generated from construction, renovation, repair, and demolition of houses, large building structures, roads, bridges, piers, and dams. C&D waste is made up of wood, steel, concrete, gypsum, masonry, plaster, metal, and asphalt. C&D waste is notable because it can contain hazardous materials such as asbestos and lead. Estimates vary, but a commonly accepted estimate is that between 15% and 20% of municipal solid waste comes from construction and demolition projects.

Landfills accepting C&D waste have limited capacity.  Many have already closed or are scheduled to close.  Currently, most of the C&D waste generated in Connecticut is disposed of in out-of-state landfills and only an estimated 7% of this is reported recycled. These figures are only reflective of the waste which passes through Connecticut permitted solid waste facilities and reported to the DEEP. The 7% reported recycled rate does not include most of the clean fill generated and reused or recycled, scrap metal recycled from construction projects, materials directly hauled from a job site to an out-of-state recycling end market, or materials reused on site.
