I don't believe the typical vanlife or tinyhome scenario is a family having such high-throughput septic, water, and food requirements. For an individual with a sane diet, altering their behavior slightly by using a simple urine-diverting waterless toilet with a bucket and whatever's convenient for dry cover material like a human-scale cat box sans urine is actually a very simple and effective solution to an individual's human waste problem. A gallon milk bottle holds multiple days worth of urine, tidily emptied where and when appropriate without any drama. In my experience you don't need that large of a container, one day capacity for urine is good enough and lighter to carry. The bucket stays dry, and is a waste disposal problem no different from a cat box. You can bury its contents in a field, or you can send it to the landfill in a bag, line the bucket with a bag like a cat box for greater convenience if you wish. In my experience a 5-gallon bucket used in this manner is good for a week. Keeping the urine and feces separate is key. A bucket containing just poop and dirt or sand/litter doesn't even have an odor and there's no splashing or other mess to worry about when handling it, it's dry. Cat boxes smell predominately of urine, by separating the urine and keeping your solids covered, the negative characteristics of a cat box are eliminated. The real challenge people embracing this lifestyle have to contend with is the judgement and ignorance of society. Don't expect the average American to come by for beers and be happy to poop in your glorified cat box. They very likely won't be coming back. Nor will your minimalist storage capacity accomodate a few beer-drinking guests; they're pissing outside. Women are often uncomfortable with anyone witnessing their menstrual waste in the urine container, and will want to wash residual blood down the diverter further increasing storage demands. It can be a very solitary life. But if you have a brain and some ability to adapt to the situation, sanitation is simply not a problem. It's just a minor inconvenience like having to clean a bathroom, plunge a toilet, or take out the trash is.
