To get a general understanding of the willow feeder idea, let's first take a quick look at alternatives.
A septic tank and drain field mixes all the poop, and greywater together, then dumps it into a tank where all the sinkers sink and floaties float. Organic matter breaks down in time. The average septic tank is pumped every four years. If you do a good job caring for what goes into the septic tank, you can go decades.
The watery layer is a sort of poop koolaid that goes to the drainfield which is placed about 18 inches below the ground level. There is a lot of bacterial activity that eats up the poopy bits from the poop koolaid, all year long. It does a pretty good job. But not a perfect job. So some poop koolaid makes it to the ground water supply. Which is why when there is enough population density, it is time to get everybody switched over to a sewage treatment plant.
The missoula sewage treatment plant, like most, collects poop, greywater, and a whole lot of awful that should not be there
(list appears. Unwanted paints, herbicides, laundry bleach, powerful soaps and detergents, household toxins, industrial toxins, industrial waste (both legal and ilegal) ...)
It also contains a heavy dose of pharmaceuticals that made it through the people that need pharmaceuticals.
Everything is sorta stirred up into a slurry, and then screened - this separates the garbage from the sewage. Garbage like flushable wipes, some TP, feminine hygiene products, plastics, etc. Garbage goes to the landfill. The remaining slurry goes to settling ponds. After 24 hours, the poop koolaid goes past a UV light and is released into the river. The floaters and sinkers go to a composting facility.
Let's try to do better. And since I am bonkers about gardening, my attempt at a solution is going to involve gardening.
A good solution requires an understanding of pathogens. For a few ailments, a person's poop can have bits of that sickness in the poop that can make other people sick. This is called a pathogen. If 4% of all people poop out pathogens, then we need solutions that will ensure that that number does not grow. For the sake of creating a good solution, lets assume that a sick person is pooping in every system.
There are some alternatives out there called composting toilets. Some of those styles actually compost. So you get a whole bunch of poop, toilet paper and sawdust together in a pile. The pile gets hot in the middle due to the composting process - often exceeding 140 degrees which makes that part of the pile sterile! Yay! Ding dong the pathogens are dead! In the middle. ... The stuff on the outside sides of the pile didn't get hot enough and still contain pathogens. Advocates for this technique encourage turning the pile frequently in an insulated container so everything (hopefully) gets hot enough at some point.
When done well, the final product is a high quality compost that smells like good soil and is gardener's gold. But .... I have some cocerns ....
I have seen some efforts at this that involve an open pile outdoors. During the composting process, can a fly land on the pile, touch a pathogen, and then fly over to somebody's food and make them sick? And if it rains, are fresh pathogens driven down into the groundwater? Further, most of the piles I have seen are either not turned, or turned only once - this makes me think that most of the contents never reached a hot enough temperature.
But here is another angle about composting in general that has *gardeners* divided.
When you compost, you might put in 100 pounds of compostable materials. To make excellent compost you turn it several times. When it is done, you have about 10 pounds of magnificent compost. Where did the rest of it go? Nearly all of what is now missing is water, carbon and nitrogen. The water went into the ground or into the atmosphere. The carbon and nitrogen went into the atmosphere. But the carbon and the nitrogen are the very things we desperately want in our soils to make our growies happy!
I want to come up with a solution that is safer when it comes to pathogens, and brings more carbon and nitrogen to my growies.
An interesting thing about pathogens ... 99% of them die in about two months. That number goes up to 99.999% in six months. And 99.9999999999% in two years. Faster in a dry environment.
As it turns out, a dry environment also stops the composting action.
So I want to dry it out and set it aside for two years - just to be super duper sure it is safe. I also want to keep it from getting onto the ground too early and keep flies out of it.
So we put it in a garbage can with a lid. The lid fits well enough that flies cannot get in, but air can move in and out. As each day warms up, the air inside expands so the moist gasses are pushed out. And as it cools at night, dry air is drawn in.
We put a piece of breather pipe in the side of the can. Then fill will four inches of sawdust. And add three more inches of sawdust to the nearly full can. Any moisture that gets to the bottom of the can is exposed to the open air through the breather pipe and can evaporate.
After two years, we have rich, pathogen free fertilizer. It would be completely safe to put on a veggie garden. Or to spread out on any garden element. But just to make sure that nobody gets weird about human poop and food, let's stick to using it on something non-food.
As the years pass, we find we want to empty the cans quickly and move on. Most plant species cannot handle this much nutrient at once. But there are a few that can. We call them the "poop beasts". Willow, cottonwood, poplar and bamboo. They will greedily gobble up as much as we can give them and then lick their plate clean. (Om nom nom nom nom)
This material is not a waste, but a valuable resource. I call all of this "the willow feeder system." Safer than a sewage treatment plant. Cheaper and scalable too.

Do you have evidence that some or most of those pharmaceuticals are disassembled by the combination of 2 years of being held in an aerated garbage can followed by surface application around a tree? If not, once released around the tree, will they get washed into the soil and into the ground-water?It also contains a heavy dose of pharmaceuticals that made it through the people that need pharmaceuticals.
Why do we care? I would add things like: this flushes all the valuable Nitrogen, Phosporus and Potassium into our waterways where it encourages algae blooms and dead zones, when in fact, kept on our land, those chemicals are a valuable resource for our plants.After 24 hours, the poop koolaid goes past a UV light and is released into the river.
Again - how does that benefit the individual? Firewood, natural cooling, feed stock for biochar to improve sandy or clay soil, feed stock for basket weaving or furniture making - I'd choose a couple of possibilities that you feel have a wide audience.But there are a few that can. We call them the "poop beasts". Willow, cottonwood, poplar and bamboo. They will greedily gobble up as much as we can give them and then lick their plate clean.

willow feeder
This is not a toilet, not even a composting toilet. This material is not "waste", it is a valuable resource - it is "candy" for willow trees.
pee outside For all practical purposes, urine is sterile.
Urine is a nearly magical fertilizer. A bit salty, but with a bit of rain, the salt is all rinsed away while the nutrients remain.
Some plants will gladly take enormous amounts of urine (willow, rhubarb, most grasses ...), while other plants enjoy just a little. If you pee in one spot about a foot away from a plant, the plant can take as much as they like. If you pee all around the plant - it could be a bit overwhelming for the more delicate plants. Try to pee in a new spot each time you pee.
Urine mixed with poop causes a lot of stink and creates about ten times more work for this system (the cans will become too heavy for two people to lift). Please pee outside or do your best to use the provided urine diverter.
eat organic! Nearly all non-organic food contains persistent herbicides. These herbicides are used on grains and will concentrate in the fat cells of animals - so meat contains more persistent herbicides than grains! The persistent herbicides are unaffected by composting or passing through an animal. They have a half-life of 7 to 11 years. So when the willow candy is presented to the willow tree, these persistent herbicides will kill (or stunt) the willow! Please do your best to eat strictly organic.
sprinkle sawdust sparingly For us, the primary function of the sawdust is to improve the view. Maybe one cup of sawdust. Too much sawdust will fill the cans a bit too quickly. Sawdust is great for mitigating smells, but it is the general design of the willow feeder that should make it never smell and, thus, never have flies. Please do your best to keep sawdust out of the urine diverter!
close the lids/flaps This system is designed so that the box is slightly pressure negative. This makes is so there is no smell and no flies. But it can only be pressure negative when the lid is down and the can access flaps are properly closed.
poop beasts Most plant species find willow candy "too rich" - if you put a lot of willow candy near such plants, they will die. But there are some species that will gobble up all the willow candy you provide. Trees that appreciate willow candy in a cold climate include willow, poplar and cottonwood. Om nom nom nom.
composting vs. not composting Most of the material that goes into this can is carbon and nitrogen. It is therefore possible to compost it all down to just ash - about 1% of the mass of the original material - all that carbon and nitrogen go into the atmosphere. But carbon and nitrogen in their solid form are the very thing that growies desperately want! And gardeners are always searching for good sources of plant nutrients. So our willow feeder systems will attempt to keep all the carbon and nitrogen in a solid form for the willows. In other words, we will try to prevent composting by keeping this material dry.
poop and pathogens Some people are sick and their poop carries pathogens. In an effort to allow those people their privacy (and to develop a poop management system that can scale to a big city) we will treat all poop as if it contains pathogens. Those pathogens are nearly all dead in two months. And they are absolutely dead in 2 years. All of our willow candy is aged two years before feeding it to willow trees - just to be sure.

If the urine is placed on the ground, the salt ends up in the soil. Not quite a biblical level of "sowing the earth with salt", but it still implies a salt buildup.

A little blood going into the cans are fine. A bit of a water spritz with the water going into the can is fine too.

A bit of a rinse in the sink is fine.
compostable pads or tampons
Really excellent options include grasses, moss, cat tail fluff and wool. All of these can go right into the can.
Commercial products labeled as biodegradable and compostable (such as seventh generation and natracare brands) are fine in the can.

I get that - my son's 20 something girl-friend is seriously shy about such things. I could see this as an area for "educating in advance". I'm assuming most visitors to the Labs have to give basic identification in advance about age and sex? I might be a bit blunt for the job, but maybe a group of us women (ideally multiple ages - I'm in menopause, and the world's a much different place than it was when I went through my 20's!) - could write up something that could be emailed in advance. I'm guessing there's already a thread somewhere on permies that covers some of this stuff, but I've never needed to look for it?

In my 20s, I would have been very insecure about using the outdoor sink and drying lines, but now I'm 40 I would be fine with it =)
I know that Paul believes in the "pee in one spot and the plants will find it" concept, however, how do the Boots and visitors choose that "spot"? I recall reading that peeing on the big manure water-heating coil was a thing - is that still happening? Is it possible to make a large mulch pile that some sort of a "pee only" shelter could get rolled over for women who need a little more privacy than men to get the job done? (with nitrogen-loving plants around it) Again, some women are more private than others, and older women may not have the knees for squatting (some days yes, some days just not!) I cut an old toilet seat so it fits fairly securely on a 20 liter bucket with biochar and mulch in it which I keep for emergencies in my back field. At some point it will have to be emptied, but mostly it evaporates due to minimal use, but that's all I need on days when squatting is a bad idea.Maybe put the "Pee outside" part outside, on the door?

I think that the mission at this point would not be for "well" but for "well enough".
My guess is that women will have more cloth pads with them that are super clean and dry and something to carry the "no longer clean pads". Some women will simply put away the used cloth for cleaning later, or maybe do a little bit of cleaning now and the deeper cleaning later.
But ... I am a guy and have no real idea. So this is all guesswork on my part .... and little bits and bobs i have learned when women talk about this sort of thing around me (this is a permaculture site, so people are less shy about these topics).
