I've been watching a lot of van conversion videos on Youtube and lots of folks are using a composting toilet and it got me thinking about my river toilet. Seems like you could use coconut coir or peat moss in the groover to have a cheap and natural solution to reducing smell. Am I way off base or is this something that would work? Seems like that is basically what the "Selway Solution" is that Cascade sells. FYI - this isn't something I would run in a SCAT machine, just use an RV hose and dump after the trip.
