Humanure- Composting your poop!
Human waste, in the form of menstural blood, urine, hair, and feces are all naturally occuring fertilizers we quite literally throw out instead of amend our soils with. While you can use urine, blood, and hair immediately as nitrogen-rich fertilizers, feces takes a bit more processing.
The basics of transforming your feces into fertilizer is fairly simple; use carbon-rich waste (such as sawdust, fallen leaves, charcoal, etc) to top off your pile after each use. This will help absorb and mask the foul smell, but also assist with it's transformation and removal of harmful pathogens.
A simple DIY composting toilet is using a bucket, and dumping it out into an area on soil for it to decompose/ process. Another method is to have an empty raised-garden bed closed off with windows, and using that as a dumping site for feces. The sun will assist with pathogen removal. (be sure to have a vent for the smell!) In about 6 months- 2 years, it's ready to use!
While in the video waste is gathered and transported to different locations, you can set up an innoculated deep litter type of composting toilet system, and simply scoop it out when you're ready to use (no turning needed!).
Regardless of the method you use, humanure has incredible benefits for soil and plant health. It's gold we shouldn't be flushing down the toilet.
