Construction waste log & diversion calculator

Short answer: Log each haul ticket, mark it landfilled, recycled, or reused, and the log keeps your running diversion rate against your target. California's CALGreen code sets that target at 65% for new construction and many additions and alterations.

How to raise your diversion rate

  • Keep concrete, asphalt, and clean soil in their own container. They are heavy, easy to recycle, and move your rate fastest.
  • Separate metal. Scrap yards take it, and many pay for it.
  • Ask your hauler which local facilities sort mixed C&D and what recovery rate they certify.
  • Keep every weight ticket. Without a ticket, a load usually can't be counted.

Questions

What is a construction waste diversion rate?

It is the share of a project’s construction and demolition debris, by weight, that is recycled, reused, or salvaged instead of landfilled. Diverted tons divided by total tons hauled, times 100.

What does CALGreen require?

California’s Green Building Standards Code (CALGreen) requires covered new construction, and many additions and alterations, to divert at least 65% of nonhazardous construction and demolition waste (sections 4.408.1 residential, 5.408.1 nonresidential), and lets the local enforcing agency require a waste management plan and documentation. Demolition-only permits fall outside CALGreen, though local ordinances can still apply. Code editions change, so confirm the current requirement with your building department.

What counts as documentation?

Usually the weight tickets or receipts from each facility, showing date, material, tons, and whether the load was recycled or landfilled. Many building departments ask for a summary report at final inspection. This log gives you a running total and a CSV you can attach.

Does mixed debris count as diverted?

Only if the facility that receives it sorts and recycles it, and can certify a diversion rate. Ask the facility or your hauler for its certified recovery rate, and record mixed loads as landfilled unless you have that documentation.
