Calculation method
Calculation method
Measured gross waste volume (L)
Sum units/person/day × unit volume × people × days.
Packed retained volume (L)
Apply each supplied retained-volume percentage to its own measured gross volume before summing.
Whole bags required
Round packed volume up to full usable bags.
Unused bag capacity (L)
Bag count×usable bag volume − packed retained volume.
Symbols and units

- d
- Usable volume per pack-out bag (L)
Use the units shown. A list keeps the order in which you enter its values. The symbol ^ means “raised to the power of”.
Assumptions & limits
Assumptions & limits
- A common-unit volume estimate from your measured packaging rates and compaction observations. It does not prescribe disposal methods or assume items may be compressed safely.
