From reading accounts of those who use the Airhead, the compost
material is some kind of coconut pith that comes in compressed blocks
and storing it is no issue. The biggest issue with the Airhead is the
liquid storage is only a couple gallons - and the price.
One thing, I haven't read it not working, although I suppose it could
somehow fail.

The liquid can be tossed overboard anywhere, as I understand it. No FCB to
worry about. I was always concerned about storing compost material, and
availability of the "official" blocks. Don't know that you can get it just
anywhere. It's also necessary to keep it warm for the composting to work, so
it wouldn't work in northern climes over the winter during haulout.
