I often read from users, like above, that urine goes overboard. I would love to hear why its okay to put uric acid and pharmaceuticals in the ocean but not bio-degradable solid waste that has already been liquified with salt water.
Minne, I've found that guests quickly get the hang of using my composting toilet. I made up a little laminated card (bilingual, of course) with instructions on using the Nature's Head toilet. I also give non-boating guests a quick run-down on how the toilet works as I go through all the other boat stuff with them. No problems so far. A composting toilet is not very complicated to use.
I don't know what you mean by "uric acid and pharmaceuticals". What pharmaceuticals??
