Calculation method
Calculation method
Initial full food-package mass (g)
Sum packages×gross mass.
Food content consumed across supplied meals (g)
Sum packages×(gross−empty wrapper).
Total empty-package mass generated (g)
Sum packages×empty wrapper.
End-of-day carried mass including retained wrappers (g)
Fixed mass+remaining full food packages+retained wrappers after the last meal of each day.
Empty packaging still carried at finish (g)
Generated empty packaging minus packaging removed at declared disposal points.
Packaging removed at declared disposal points (g)
Remove accumulated empty packaging only when a supplied record explicitly marks a disposal point.
Symbols and units
- a
- Meal records in day order: ID, day number, full packages consumed, gross grams/package, empty-wrapper grams/package, declared disposal point after meal yes/no
- b
- Nonfood fixed carried mass (g)
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 supplied food/packaging mass ledger. Disposal flags represent externally confirmed suitable disposal points; wrappers are not assumed to vanish when food is eaten. This is not a nutrition prescription or waste-disposal permission.
