This is a badge bit (
BB) that is part of the
PEM curriculum. Completing this BB is part of getting the
straw badge in
Waste Streams.
Are you ready for a sticky subject? You guessed it, it's
poop. I like the
Humanure Handbook but Paul Wheaton has some ideas about poop as well. Let's make an adaptation of his
willow feeder that stays put. This is intended to be for infrequent use, perhaps near a garden.
Here's the idea. It is a garbage can with a toilet seat in the place of the lid. You contribute to it like a normal willow feeder except there is no
urine diverter and you can urinate into it (ideally only when pooping). The can can be sunk into the ground but emptying in the future will be trickier. A black vent pipe extends 20 or more feet up the sunny side of a tree or post to draw air up like a chimney. Another vent enters the can through the lid and goes down an inch from the bottom. There is an insect screen on that vent. This is intended for infrequent use, perhaps 5 times a week. It might take many years to fill up. At that point the normal lid is attached (with the same vents) and it rests and ventilates for two years before going to a willow tree. A second willow can would then be put into service.
This is a new idea so there aren't any videos of it. Here's one of emptying willow cans though:
Minimum requirements:
- Experiment with a simpler willow feeder for infrequent use
- Twenty foot high
solar chimney vent at least 2" in diameter
- Screened air vent to bottom of can (from lid) at least 2" in diameter
- Body of garbage can is not modified
- Toilet seat for comfort
- Copious sawdust for covering deposits
Provide proof of the following as pictures or
video (<2 min):
- Can with new toilet seat lid and vent pipe holes
- View into can when ready for its first deposit
- Black vent pipe in a tree or up a pole on the sunny side
- Paragraph or two about how it has worked after at least 20 deposits
