From what I've been reading it seems easy enough to make my own composting toilet. Am I missing something or is it just a 5 gal bucket and layers of peat moss or sawdust? I've seen some people put the bucket in a box(which I plan to do). Is a fan necessary in the box? Where can I get rid of the waste when the bucket is full, other than the trash preferably. Can I just dig a hole in the woods and put it in there? What am I missing? Thanks.
