The portion of project debris that was recycled or salvaged rather than landfilled.

Total the weight from all recycling/salvage streams (e.g. metal, concrete, wood, cardboard) using hauler diversion reports or facility weight tickets where available.

The total weight of all debris generated by the project, recycled and landfilled combined.

This should equal the recycled/salvaged weight plus whatever was sent to landfill, from the same reporting period.

High confidence

Verify your specific certification program's (e.g. LEED) exact calculation methodology and documentation requirements (weight tickets, hauler diversion reports) — some programs exclude certain material categories or require third-party-verified weight tickets rather than estimates.

Then change the inputs to see how far the answer moves.

How this was calculated

Formula source(s)

  • Diversion rate (%) = Recycled/Salvaged Weight ÷ Total Debris Weight × 100 — the standard metric used in construction waste management plans and green building certification programs (e.g. LEED Materials & Resources credits) to report the fraction of project debris kept out of landfill.

What this calculation does not cover

  • The rate is weight divided by weight — nothing in it knows what the material was. One heavy inert stream, concrete or scrap steel, can carry the entire percentage while most of the light packaging and mixed waste on site still goes to landfill.
  • It counts weight that left site in a recycling or salvage container, not weight that was actually reprocessed. Loads rejected as contaminated at the sorting facility, sorting residues, and material burned for energy or used as landfill cover all still count as diverted here.
  • Excavated soil, land-clearing arisings, and hazardous or otherwise regulated streams are treated as ordinary debris weight if you enter them. Whether they may be counted at all, and on which side of the sum, is set by the scheme you report to, not by this arithmetic.
  • Nothing checks that your two figures cover the same scope or the same reporting period, and the calculation produces no evidence of its own. It does not replace the weighbridge tickets and hauler diversion reports a submittal is judged on, and some programs will not accept an estimated figure at all.
  • There is no threshold anywhere in this calculation. It will not tell you whether the number you get earns a certification credit, meets your project waste management plan's target, or satisfies a local diversion ordinance — those baselines and their counting rules live in the scheme document.

How to calculate C&D debris recycling diversion rate in 3 steps

  1. Recycled/Salvaged Debris WeightThe portion of project debris that was recycled or salvaged rather than landfilled.
  2. Total Debris Weight GeneratedThe total weight of all debris generated by the project, recycled and landfilled combined.
  3. Recycling diversion rateThe tool computes the recycling diversion rate from those figures and shows the formula, its sources, and a confidence rating alongside it.

Frequently asked questions

How is the diversion rate calculated?
Diversion rate (%) = Recycled/Salvaged Debris Weight ÷ Total Debris Weight Generated × 100 — the standard metric used in construction waste management plans and green building certification programs to report the share of project debris kept out of landfill.
Why does this metric matter for a construction project?
It's the standard reporting figure used in construction waste management plans and green building certification programs, such as LEED Materials & Resources credits, to document how much project debris was recycled or salvaged instead of landfilled.
Can I use this number directly for LEED or another certification submittal?
Only after checking your certification program's exact calculation methodology and documentation requirements: some programs exclude certain material categories or require third-party-verified weight tickets rather than an estimate like this one.
Preliminary estimate, not certified engineering. This tool produces an indicative quantity calculation for planning purposes only — it is not a certified structural analysis, a guaranteed material takeoff, or a substitute for building department approval. Always verify measurements on-site and have a licensed contractor or structural engineer review any load-bearing, code-sensitive, or safety-critical work before purchasing materials or starting construction.
