Some will seriously scoff at this but we have a Wrappon Green portable toilet. Originally designed for Crane Operators and disasters but it’s a “flushable” toilet that completely seals the waste and allows it to be disposed of with normal trash. Yes I know it’s sealing your waste in Plastic, the company is working on a biodegradable solution. But it’s not an all the time thing. Most of the time there’s a bathroom or a place to dig a hole but not always. Plus we do a fair amount of desert camping and you can’t leave waste buried in the desert at all. The other plus is no water, which is obviously a valued commodity camping in the desert. Anyway I’ll prob get flamed for vacuum sealing my waste but it keeps my wife happy, it’s super sanitary and certainly quick and easy. Just food for thought. Only downside I’ve found is the unit, and the “per flush” price are quite high. But again it’s not like it’s used everyday, it’s a very small price to pay to have my wife along with me.
