Take a look at the sawdust toilet (

I had to laugh at this line:

Experience has shown that 150 people will require four five gallon
containers during a serious party. Therefore, always be prepared for
the unexpected, and maintain a reserve toilet capacity at all times by
having extra toilet receptacles available, as well as extra cover
material. Incidentally, for every full container of compost material
carried out of a toilet room, a full, same-sized container of cover
material will need to be carried in.


I don't know how I'd find 150 people willing to attend a "serious
party" where the toilet facility was a bucket of sawdust. :-)

If you use a sawdust or peat moss toilet aboard a boat, you need to
haul a quantity of sawdust or peat moss- hardly practical if there
isn't room for a typical porta-potti...
and then you still have to figure out a way to dump it somewhere. I
can't imagine that it would be easy to get the sawdust or peat moss
into the "pump out hose" at the marina.
