The great majority of us are wasting the nutrients we excrete. This state of affairs makes not a bit of sense at all. For homesteaders, finding some way to utilize the nutrients that are leaving our bodies seems like it should be something of a priority. We can’t afford to hemorrhage nutrients out of our living systems and we shouldn’t even if we can re-import them from somewhere else. While saving urine to use as a fertilizer will catch the vast majority of the useful plant nutrients leaving your bodies, and is a great first start, doodie also has a lot of good stuff that can be turned to advantage. This system seems very promising to me. It’s going to be too much work for some people, but for tough and scrappy homesteader types and less “developed” cultures and areas, it is probably fine. The prospect of the opportunity to create super soil zones by utilizing immediately available resources and a trickle of labor from already daily activity, gets me all hot and bothered and would light a fire under my ass to go start digging if said ass wasn't glued to a chair most of the time. I mean that shit is exciting people!
My proposal is really for a system which modifies the soil to quite a depth, but I suppose it could be used in a shallower form too. For a system that required more upfront investment, but less labor over all, the ecosan system with charcoal added to the ash might be a good way to go. Briefly, the Ecosan system uses two pits. Urine is diverted out of the system and collected in containers for direct use. Each time a solid deposit is made, a handful of ash is added to cover it, help dry it out, and alkalize it, all of which kills off microorganisms. The collection chambers are ventilated to encourage drying. Once one pit is “full” it is closed off to dry completely, and the other side is used. By the time pit two is full, six months or more later, pit one is completely dry and innocuous. If charcoal was added, it would pre-charge the char as well and the whole lot could be pulverized as a very rich, fertilizer for use primarily on annual crops.
Here at Turkeysong I could see running both systems eventually. I’m pretty tough, and am used to inconvenience from years of re-training my entitlement set points. I'll spare you the details, but trust me, I have gotten through the worst of times with the most inconvenient toilet and living situations, like no toilets at all and extremely ill, rain or shine, day and night. But, um, honestly, tough or not, I’d rather sometimes have a close outhouse to visit! Inconvenience isn’t the goal or noble in and of itself. Sometimes simple solutions are still the most elegant ones though and being constantly besieged by convenience can make us into weak and whiny people.
I’m pretty opposed to the idea of indoor bathrooms. Digging little holes in the forest or crapping in a trench might seem crude, but pooping in your house just seems plain uncivilized to me. I could see both the Ecosan and trench systems eventually operating simultaneously in a place like this. The cozy, luxurious Ecosan, (maybe with a door, or a light and some reading material even! How about a stereo, wide screen t.v... wifi...) close to sleeping quarters for late nights and rainy days, and the biochar trench latrine for the rest of the time, or for special soil improvement projects.
I hope this idea will appeal to someone enough to try it out and we can see what the profits and pitfalls might be. Obviously, making a bunch of charcoal is in order, quite a lot actually. The good thing is that once it's made, it keeps forever. I managed this past winter and spring to experiment a little with the top down burn pile and pit methods of charcoal production. Both are easy and accessible and can be used with random scrappy brush. I’ll leave you with the super condensed version of both, but stay tuned for more on those in future posts or videos.
Top down piles: Pile brush in a tall narrow pile. A tall narrow pile is more work, but it burns better than a mound shaped pile. Light from the top which produces way less smoke. Throw unburned pieces from the outside into the center as burning progresses. When most of the wood is charred and no longer flaming, douse with water.
