What are you doing for grid down sanitation? Poop Plan?
I have been using the Humanure Handbook method for about two years. Hardwood sawdust is hard to come by so I’ve used softwood sawdust, shavings, peat moss, grasses/leaves and even wood ash. The shavings are too large to contain the odors, the grass/leaves can be too, but everything else is easy.
I get about 2-3 weeks out of a 5 gallon bucket as a single person. I’ll be using my first batch of 2 year compost this year. I like how I keep fertility on my land and save on septic pumping and whatever disposal method is used. Just keep all 5 exposed sides of your compost pile protected from animals and you’re good to go.
