I am going to take up the van life as a part time thing, and I definitely want a composting toilet instead of a chemical toilet or RV-style blackwater micro-shitter.
Just the thought of having both a composting toilet and a live-in van really gets my "alternative lifestyle" self excited. Squee!
I understand that Stephen has a 5 gallon bucket composting toilet in his van and he uses an ingenious method of providing ventilation through holes in the van floor. I may do that, but it makes me nervous.
Cover material seems to be an open question. Sawdust I regard as king of kings, while plenty of people use other things, even cat litter.
Using a plastic trash bag inside the 5 gallon bucket should make it easy to dispose of waste. Conceptually I grasp the importance of "humanure" yet I am not equipped with a humanure pile (I live in an apartment). So I will dispose of this waste like millions dispose of pet waste or dirty diapers. I'll throw it in the trash.
My question is for vandwellers with toilets. (Understandably, this is a small slice of the population). What sort of ventilation do you have for your toilet? Is it composting or otherwise? If you have a vent, do you use a vent fan, or is it a passive stack?
