Landfill remaining permitted capacity estimates the disposal airspace or tonnage still available under existing landfill permits.

It is a disposal-runway estimate, not current-period landfill volume.

Landfill capacity is consumed as waste is accepted

Waste companies capitalize landfill development costs and generally recognize depletion as permitted disposal capacity is used.

Republic Services states that its landfill depletion rate depends on the landfill development asset, estimated future development costs, and estimated remaining permitted and probable disposal capacity.

As waste enters the landfill, the available capacity declines and additional cells, expansions, or new permits may be needed.

Remaining capacity is an estimate

The estimate can change because of:

  • engineering design updates;
  • compaction performance;
  • waste density;
  • permit expansions;
  • regulatory decisions;
  • future development plans; and
  • changes in expected waste flows.

Companies therefore review capacity assumptions periodically and can revise depletion rates prospectively.

Permitted and probable capacity are not the same

Permitted capacity has existing regulatory approval.

Probable capacity can include expansions management expects to obtain but that may still depend on technical and regulatory processes.

Investors should preserve that distinction instead of combining all potential airspace into one certain figure.

Primary-source examples

Landfill remaining permitted capacity is most useful as a landfill disposal-runway measure. It complements Landfill Depletable Tons, but it is estimation-heavy and should not be compared across issuers without matching definitions.

Part of the Waste & Environmental Services Operating Model

Connect price, realized yield, service volume, internalization, landfill usage and capacity, recycled commodity prices, transfer and recycling infrastructure, renewable-energy facilities, and capital reinvestment to understand environmental-services economics.

How the model fits together
  • Price and service volume: Collection and disposal volume captures service activity, while core price and average yield separate announced pricing from realized revenue effects. Mix and service changes can make average yield differ from core price.
  • Network capture and commodity exposure: Internalization shows how much collected waste stays within owned disposal assets, landfill depletable tons show disposal usage, and recycled commodity price per ton adds a separate commodity-sensitive earnings driver.
  • Network capacity, resource recovery, and reinvestment: Landfill site count and remaining permitted landfill capacity describe disposal footprint and runway, while transfer-station and recycling-facility counts describe intermediate handling and resource-recovery infrastructure. Renewable-energy facility count adds landfill-gas monetization context, and capital expenditures show reinvestment across vehicles, landfills, facilities, recycling, and energy assets. These issuer-defined measures add network and capital context rather than forming a standardized cross-company formula.
