Composting / soil generation
Humanure Handbook
This method of composting includes poop, so if you don't want to read about composting your poop, please skip to another section.
Including your poop attracts bacteria who really heat up the compost and break down the contents, and they can also break down toxins if you apply the compost to a toxic environment.
This method involves a lot of buckets. Some buckets are for poop and pee, and other buckets are for the usual kitchen scraps. For your poop and pee bucket, you could use a toilet seat on top, and you could make or buy a fancy box to hide the bucket. Along with this setup, you would have a lot of wet sawdust, and in another bucket, you would keep some wet sawdust. Outside, you'd have a whole pile of sawdust underneath the sky where the rain can keep it wet. After pooping/peeing, you would add enough wet sawdust to eliminate the smell.
After about a dozen buckets, it's time to make your compost. You would make a box out of pallets. Then, you would line the pallet box with bales of hay. Next, you would dump the contents of your buckets into the hay pallet box. Lastly, you would cover the contents with more hay and let it sit there undisturbed until it finished turning into compost.
