An Overview of Compost Toilets, AKA the “Magical Waterless Toilets”


There, this is our waterless toilet. Average flush toilet uses 30,000 liters of water, per person, per year. This toilet is a dry composting toilet. You might only use some water
to wash and clean yourself. It’s a minimum water use toilet and the end product is a
high quality soil amendment you can use to grow forestry trees. Doesn’t smell, it’s clean, it looks exactly like a
normal toilet, on the use end, it gets delivered to a
sensible processing system. Local, no infrastructure required, outside of the building footprint. We have six compost toilet systems here. And they’re all batch systems. They’re a manufactured item. They’re set up inside with
aeration, gauzes and meshes to aerate the humanure
which has sawdust or leaf, spare leaf material put in after each use. There’s a 12 volt fan running
here, it’s solar powered which gives us extra aeration and takes any potential smells
away so they don’t smell. And there’s a urine drain at the bottom that joins our gray-water drainage system coming from our kitchens and our showers, which goes down to a reed bed which is a biological cleaning system. So all the cleaning here, all the waste water, all the black water, is cleaned with biology. There’s biology decomposing
the humanure here with high carbon additives after each use and there’s reed bed reeds with their roots taking
out the suspended nutrient and potential minor toxins
out of the gray-water, then soak into the landscape. So the gray-water’s dealt with and is part of the
re-hydration of the landscape and all cleaned up with biology reeds. Here, the composted material
is kept in these units until when they’re full,
they sit for a few months and turn to a soil amendment. It becomes a high
quality compost to add to tree growing systems. So we take it out, we
don’t put it to food crops. Just to be absolutely safe and sure, we have general, we have the
public coming through here so we put it onto farm forestry trees and it grows on and
becomes high quality trees.

  1. Absolute need of the day , specially they should be installed in public toilet systems and places of tourism interest.

  2. My compound in Africa has composting toilet outhouse for the workers which work like yours in the video, but were made from local materials. They do produce very nice compost looking material and do not smell. I really struggle with what to do with the composted material. The property is 5 acres and has food gardens and fruit and nut trees. I do not understand where the material could be used safely. How far from food gardens and trees should it be used? Where could I learn more.

  3. Will you be doing a video on the use, cleaning, and maintenance of the system? You mentioned in this video that extra carbon is put in after each use, but didn't explain how, amount, etc. Is there a bucket of wood chips and a shovel in the bathroom or what? Isn't it odd that something so basic to human needs is such a mystery to many of us these days?

  4. I've been using the humanure composting system for about 5 years and loving it. Since I live alone, in my 224 sq ft cabin, I use 5 gallon buckets instead of the large system you have designed.
    Makes some of the richest compost I've ever seen.

  5. Видео надо начинать словами: "если у вас на участке завалялся лишний морской контейнер, то не спешите его сдавать на металл. Сделайте лучше из него туалет на 6 человек."

  6. I like that you dont divert the urine first, allow it to flow through and out from the humanure.

  7. Hey! Where Can we found a list of "légumes tree" because there is no équivalent words in french

  8. Waaaaaaay too high-tech in my opinion. A bucket, a self-made seat, sawdust, a compost pile, that’s all that’s needed. Joe Jenkins makes it low-tech and easy, and it works wonderfully. If anyone wants low-tech ideas, read The Humanure Handbook by Joseph Jenkins.

  9. Seems awfully complicated, my favorite dry toilet is a two story system with a cubicle built above a compost heap, really simple, no playing with faeces, easy to empty and you get to "go" in the trees!

    All built from sustainable lumber and home built in a day.

    What could be better!!

  10. Somebody tell Bill Gates, the waterless toilet he's been investing millions in, is already invented.

  11. Women should not use toilets with sawdust: the tiny particles that fly with the smallest breeze (to open and close the door or to move the seat are enough) will give irritations in a place of yourself where you don't want them.

  12. The flushing toilet …the best and worst invention in history. Can’t wait to install composting toilet in new house 👌
