One of the biggest components in the design of composting toilets(even redneck designs) is separation of urine from the “poop pot”. You must do this to eliminate moisture from the compost, and decrease and eliminate the smell associated with latrines. This weekend I built the second prototype for urine diversion. The first had several glued and over-layed strips of PVC, so I built a simpler design with two pieces – one that is inserted onto the frame of the toilet, and the other, a funnel that is inserted into the urine container. I have been pooping and pissing in it all week. It works great!!
