A precise total cannot be calculated from currently available data because there is no global system that records human waste generated aboard all forms of transportation. Operators generally measure only what is removed from waste tanks during servicing, and many transport modes discharge into sewer systems or use toilets only intermittently. Vomit, mucus, and similar biological waste are almost never tracked separately.
However, a rough engineering estimate can be made using average human excretion rates and assumptions about passenger occupancy.
Example global estimate for transportation
Suppose, on an average day:
Around 5 billion passenger trips occur worldwide across road, rail, air, and water.
Only 5–10% of travelers actually use a toilet while traveling.
Average toilet use produces:
Urine: ~0.3 L
Feces: ~0.15 kg
That gives approximately:
By transportation category
Approximate contribution to onboard toilet waste:
Road
Luxury coaches
Long-distance buses
Motorhomes/RVs
Some limousines
Rail
Metro systems (limited)
Intercity trains
High-speed rail
Sleeper trains
Luxury trains
Air
Regional aircraft
Commercial airliners
Private jets
Business jets
Water
Ferries
Cruise ships
Luxury yachts
Cargo ships (crew)
Naval vessels
Important considerations
Cruise ships generate the highest amount of onboard human waste per vehicle, because thousands of people remain aboard continuously for days.
Commercial aircraft generate relatively little waste per passenger because flights are short and not every passenger uses the lavatory.
Long-distance trains generate much morewaste than commuter trains.
Luxury buses and sleeper coachesproduce more onboard waste than citybuses because of longer journeys andonboard toilets.
Most private cars, taxis, and motorcyclesgenerate essentially no onboard toilet wastebecause they generally have no restroomfacilities.
So, if you're asking about all public andprivate transportation worldwide, a reasonable order-of-magnitude estimate is:
Urine: roughly 27–54 billion liters (7–14 billion US gallons) per year
Feces: roughly 1.4–2.7 million metric tonnes per year
Vomit and mucus: no credible globalestimates exist because they are infrequentand not systematically measured.
