Rob Rohde-Szudy has a nice article over at Duckworks Magazine outlining making your own composting toilet. Composting (or dry) toilets are all the rage for the marine world I think... given the growing limits on dumping and waste removal, having a toilet that has not holding tank, no pumpouts, etc. might be just the thing.

Sun-mar and others make commercial units, but something like this might work really well for me on my boat. What I didn't see outlined is what you do with the toilet paper... anybody know?
