Construction and demolition (C&D) waste comes from building, renovation, demolition, roadwork, and—in some definitions—site clearing. It can include materials such as concrete, wood, asphalt, drywall, metals, brick, glass, and salvaged fixtures. Demolition can also release fugitive dust; the U.S. Environmental Protection Agency (EPA) warns that dust may contain harmful amounts of lead. What counts as C&D waste and what dust controls apply depend on the jurisdiction and the specific project.
What is construction and demolition waste?
C&D debris is waste generated by construction, renovation, and demolition. EPA treats it as a category separate from municipal solid waste. Its material-specific estimate covers work on buildings, roads, and bridges, so the category is broader than debris from building demolition alone.

The term is useful for describing waste streams, but it does not have one perfectly uniform boundary across every dataset or jurisdiction. A report may count only materials from buildings and infrastructure, while a landfill or state definition may also include excavated or land-clearing material. When the legal classification matters, use the applicable state and local definition rather than assuming every item below is included everywhere.

This variation matters when comparing figures as well as when deciding how to classify a load. The phrase “C&D waste” can describe material grouped by the activity that produced it, by the type of material, or by what a particular disposal facility accepts. A source that counts roadwork and site clearance is not necessarily measuring the same boundary as one focused on building materials. Before comparing two totals, check both the activities included and the materials counted.

What does C&D waste include?
Common C&D materials include both structural materials and items removed during renovation or demolition. EPA’s examples span building work, roads, and site clearance.
| Material or source | Examples |
|---|---|
| Concrete and masonry | Concrete, brick, clay tile, and other masonry |
| Wood and building products | Building wood, steel, drywall, plaster, and gypsum |
| Road and roofing materials | Asphalt concrete from roads and asphalt shingles |
| Other building materials | Metals, glass, plastics, and salvaged doors, windows, and plumbing fixtures |
| Excavation and site clearance | Excavated material, earth, rock, trees, and stumps; these may be included in broader landfill categories or some state definitions |
EPA describes C&D landfill waste as typically including roadwork material, excavated material, demolition waste, construction and renovation waste, and site-clearance waste. That landfill description is not a universal rule for how each state or dataset defines C&D debris. EPA’s historical characterization report notes that some state definitions include land-clearing debris.
One practical way to read a list of C&D materials is to separate the source activity from the material boundary. Construction, renovation, demolition, roadwork, and site clearance are possible sources. Concrete, gypsum, metals, or trees are material examples. A source may include some of those activities and materials but not others. In particular, earth, rock, trees, and stumps from clearing should not automatically be assumed to fall under every state’s C&D definition.

Contaminated materials need a separate determination
Do not assume that a material belongs in an ordinary C&D waste stream simply because it came from a building. EPA says C&D landfills generally do not receive hazardous waste or industrial solid waste unless permitted under applicable standards. It also notes that building materials containing lead and asbestos are regulated by EPA. The correct handling and disposal route depends on the material and applicable rules, so check with the relevant regulator or permitting authority before disposing of suspected contaminated materials.
This is a boundary and compliance issue, not a complete disposal guide: the general description of C&D landfill contents does not determine how a specific suspected hazardous or regulated material must be handled. If a material may contain lead or asbestos, check applicable requirements rather than treating it as ordinary debris based only on its origin or appearance.

How much C&D waste is generated?
EPA estimated that the United States generated 600 million tons of C&D debris in 2018—more than twice the amount of municipal solid waste generated that year. This is a dated estimate for 2018, not a current annual total.
A separate EPA science communication page published in 2019 stated that C&D disposal facilities receive between 230 million and 530 million metric tons each year. That range describes material received by disposal facilities; it is not interchangeable with EPA’s 2018 estimate of waste generated. The figures use different measures and source contexts, so they should not be treated as competing measurements of the same annual total.

One figure estimates the amount produced; the other is a range for what disposal facilities receive each year. The 2018 generation estimate is stated in tons, while the 2019 page’s facility-receipt range is in metric tons. Keep each figure attached to its measure, unit, and source context when citing it. Neither number, on its own, tells a reader how much material was recycled, reused, or disposed of at a particular site.
These national figures provide scale, not a forecast for a local project or a current-year total. They also do not resolve the differences in category boundaries: what a source includes can affect what its total represents. For a meaningful comparison, look for the year, whether the figure is generation or facility receipts, the unit, and the included activities and materials.
How does demolition dust affect air quality?
Demolition can create fugitive dust: dust released into the air rather than captured at the source. EPA warns that this dust may contain harmful amounts of lead and identifies dust as the most common route of lead exposure. EPA also states, “Fugitive dust is a serious concern for people who are especially sensitive or vulnerable to the effects of dust.” This statement is from EPA’s “Managing Stormwater and Dust at Demolition Sites” page.

This is a potential concern, not a claim that every demolition project produces lead-bearing dust or that all nearby people experience the same exposure. The cited EPA guidance does not quantify concentrations, exposure distances, or health risks for particular activities or sites. Actual conditions depend on the materials and work underway, among other site-specific factors; a universal neighborhood impact cannot be inferred from the general warning.
The source supports a specific pathway: demolition activity can release fugitive dust, and dust may contain harmful amounts of lead; EPA identifies dust as the most common way people are exposed to lead. It does not provide a quantified air-quality profile for each demolition task or a numerical estimate of a neighbor’s exposure. Avoid turning the warning into a claim that lead is present at every site, or that a particular distance or duration is safe or unsafe based on these pages alone.
That distinction is useful for residents and project teams alike. The general warning explains why dust deserves attention, especially for people who are sensitive or vulnerable to its effects. It is not a site assessment, a measurement, or proof of the composition of dust from a particular building. Site-specific concerns require the applicable project information and regulator guidance.
How do you control dust during demolition?
EPA illustrates water spraying during home demolition as a dust-control measure. A water spray or misting nozzle can apply suppression, but the equipment alone does not establish that a project meets its requirements. Applicable controls can vary with the site, jurisdiction, permit, and contract.
- Check the project’s permit and contract. Look for dust-control provisions and any required work practices or monitoring. A demolition permit or contract may set conditions even when a general rule is not immediately apparent.
- Ask the relevant authorities what applies. Contact local and state environmental regulators and, where applicable, the office issuing the demolition permit. Requirements may come from local, county, state, or federal rules.
- Plan controls for the actual work. Use the applicable project requirements to determine how dust will be suppressed during demolition. EPA’s water-spray example illustrates one method, not a universal prescription or guarantee of compliance.
- Recheck if conditions or scope change. If the work, materials, or site conditions differ from what was covered by the original plan or permit, confirm whether the required controls need to change with the issuing office or regulator.
For a practical first check, identify who is issuing the demolition permit, review the permit and contract for dust provisions, and ask local and state environmental regulators which requirements apply. This directs the project team to the authorities named in EPA’s general advice without assuming that one rule applies everywhere. Where a permit or contract specifies controls, those project terms matter even if a general rule is not obvious to the reader.

EPA’s guidance is general. It does not replace the rules, permit conditions, or regulator directions for a specific project. Confirm requirements before work begins rather than assuming a single piece of equipment is sufficient. Water spraying is an example of a dust-suppression method, not evidence by itself that all dust is controlled or that a project complies with every applicable requirement.

Two useful questions clarify why estimates and requirements may not line up:
- What activity is counted? A category may cover construction, renovation, demolition, roadwork, or site clearance—or only some of these.
- Which materials are inside the boundary? Some accounting focuses on building and infrastructure materials; other definitions may include excavated or land-clearing debris.
Dust controls have a similar project-specific dimension: the work and its conditions matter, while the applicable requirements may be set at different levels of government or in permit and contract terms. For a waste statistic, check what activities and materials the source counted. For a project, check the local and state definition and the actual permit conditions.
In short, there are two separate questions to keep straight: what a jurisdiction or dataset classifies as C&D debris, and what dust measures a particular demolition project must follow. EPA’s national examples help explain the category and the potential dust concern; they do not establish a universal legal definition or a universal control plan. If the classification affects disposal, or if a project’s requirements are unclear, consult the relevant state or local regulator and permitting office.

Is construction and demolition waste the same as municipal solid waste?
No. EPA describes C&D debris as a type of waste not included in municipal solid waste. EPA’s 2018 estimate said U.S. C&D debris generation was more than twice the amount of municipal solid waste generated that year.

Does C&D waste always include trees, soil, and rocks?
No. Trees, stumps, earth, and rock from site clearing appear in broader landfill descriptions, and EPA notes that land-clearing debris is included in some state definitions. Check the applicable state and local definition rather than assuming those materials are included everywhere.
Does demolition dust always contain lead?
No. EPA warns that fugitive dust may contain harmful amounts of lead; that is a potential concern, not a claim about every demolition site. The cited guidance does not quantify the lead content or exposure level at a specific project.
Is spraying water enough to meet demolition dust requirements?
Not necessarily. EPA illustrates water spraying as a dust-control measure, but requirements are site-specific and may come from local, county, state, or federal rules, permits, or contracts. Confirm the project’s conditions with local and state environmental regulators and the applicable permit office.

Which EPA C&D waste figure should I use?
Use the figure that matches the question and preserve its context. EPA estimated 600 million tons generated in the United States in 2018. A separate 2019 EPA page gave a range of 230 million to 530 million metric tons received by C&D disposal facilities each year. These are different measures and should not be treated as competing totals for the same year.
Where should I check if a material may contain asbestos or lead?
EPA notes that building materials containing lead and asbestos are regulated by EPA, and that C&D landfills generally do not receive hazardous or industrial solid waste unless permitted under applicable standards. For a specific material, check applicable rules with the relevant regulator or permitting authority rather than assuming ordinary C&D disposal applies.
The Bottom Line
C&D waste can include debris from buildings, roads, and site clearance, but its exact boundary varies by source and jurisdiction. EPA’s 2018 generation estimate is historical, and its separate disposal-facility range measures something different. Demolition dust may contain harmful amounts of lead, so check the project’s permit, contract, and applicable regulator guidance for dust controls; a water spray is an example, not a compliance guarantee.
