I never do that in a box because I don't use any paper products, I just go in the various containers I've found at the dump over the years that I keep in my house. Most of the time, I shit into a tupper ware. I also like metal containers like the ones you use for camping or in the military. then i freeze them or keep them in the refrigerator for a few days. if you really seal the container tight, the shit can be stored much longer.
Have you ever tried to shove a frozen turd up your ass? I would highly recommend it unless you are inexperienced in the practice of Anal Brutalization. Although my feces fixation originally stems from my dislike for the idea that I am leaving waste upon the earth. For as long as I can remember, I've always felt that wiping oneself after a bowel movement was a complete waste of precious natural resources. Then when I was about 12, I found out on my own that if you re-insert it, or consume it, your shit (made out of previous shits) will eventually become smaller and smaller and then waterier and waterier, and thus, produces much less physical waste than the you normally would shitting in a toilet like all the judgemental sheeple that posted in this topic.
As for my urine, I'd estimate that 3/4ths of the time it's all I drink, straight from the source too, if you know what I mean. Whenever it rains, I collect the water in a gallon bucket (that I crafted out of semi-frozen fecal material, and baked in my homemade solar kiln/oven like a ceramic pot; it turned out to be surprisingly durable so I still use it) that I place under the end of gutter and drink about half a liter once or twice a week to dilute the concentration of uric acid. In the drier seasons from late summer to autumn, it doesn't rain as much as usual, so keeping this up becomes a little difficult, but I find it to be worth it in the long run. I never use a plastic bottle because, as an amateur guerrilla environmentalist, I find using unrenewable resources to be a more repulsive act than the actions described throughout this thread.
As for hygiene, I suppose never really clean up or shower unless you count walking around in the rain once in a while. The dried shit flakes off my body and sometimes i'll brush a bit out of my beard. Hell yes, I STINK. And I've been told my mouth smells like a sewer. That's theway I like it, and I'm damn proud! I may clear a few people out of a room when I walk in (although this isn't always due to my odor, I've been told I can be very longwinded when it comes to discussing my lifestyle, which I do as frequently as possible) but I haven't been thrown out of a Trader Joe's or Church yet. I don't live the way I do for you, I do it for Mother Earth and God, if you don't like it, deal with it, cuz I ain't changing any time soon (not my clothes and especially not my behavior).
