If I saved the sawdust from the firewood I cut up every year we would have plenty to use in an outhouse or for composting. Right now I throw it out. My wife composts her garden with maple leaves of which we have tons every year and food scraps. Sometimes we buy a pickup bed worth of horse manure. We could do rabbits or chickens manure but the nimby town ordinances are against it. Buying it is ok we just can’t produce it. We used to have ducks as pets. Not anymore, too much poop! It also became a chore livetrapping all the critters they attracted. Humanure is a psychological issue with my wife. She might do it if the circumstances were survivalist but otherwise no no no. We’re not down to the bucket yet.
