The average toilet uses 30,000 litres of water per person every year, but dry composting toilets only use the amount needed to clean them. And, they produce high-quality soil amendment (compost) for forestry trees. These toilet systems need no infrastructure beyond the bathroom’s footprint, and at Zaytuna Farm’s toilet block, six toilets run via manufactured batch systems that have gauzes and meshes to help aerate the human manure. Sawdust or shredded leaf material is added after each use. A solar-powered 12-volt fan adds extra aeration that whisks away any potential smells. Urine drains from the bottom into a greywater system that uses reed beds, and all solid waste and blackwater is cleaned via biological processes. The finished compost is used on forestry trees, not food crops, to be completely safe.

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.

Im sure some students/shareholders would be a little intimidated walking to the bathroom and seeing a bucket full of woodchip and 10 other peoples shit lol, its not exactly the norm in the modern age.

@svenrohark5307 3 года назад

here in spain we use very simple systems that are also much smaller, completely odorless .... For example, we use a flower pot that is under a tree that needs fertilization. Next to it is a bucket with pounded charcoal and a small hand shovel made of stainless steel, copper or half a coconut shell. If the flower pot is used for the first time, sprinkle some charcoal powder into it. Then you crouch over it. The urine flows into the earth to the tree. The shit is covered with charcoal pulfer. When the flower pot is full, it is emptied into the worm farm. We also use normal buckets. Some have a toilet seat. This is then regularly emptied into a larger container with holes. A bicycle basket is also good. It's under a tree that needs fertilizer. when the basket is full, it comes back to the worm farm.

@svenrohark5307 3 года назад

better is a worm farm compost toilet. something like this can easily be built without plastic. Turning shit into worm soil is revolutionary. it's better to always use homemade charcoal powder in the composting toilet.

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.

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?

@wyattbottorff2473 5 лет назад

Just enough to cover the deposit. Very little different, I imagine, from the bucket system in use for ages.

@joejolly3430 3 года назад

There's another video where Jeff recommends a 20l deposit of clean carbon rich material on the bottom layer to start it off. I wonder how often we should clean the shade cloth filter or just replace it after every full cycle?

@@wyattbottorff2473 - There's this permanent misconception, semantic if you will. Mixing the bucket (no composting), latrine, outhouse, etc. Putting it simply, ANY of those other "systems", if we can call that! Are nasty to say the least. The pungent smell being probably the worse of it all! And the worse give away of those systems! Generating an incredibly bad reputation to all those who cannot see beyond! Humanure as it's so politically correctly called nowadays! It's a giant step forward in the most simple form imaginable. ADDED carbon, usually in the form of sawdust and the likes! That followed by a period of real active composting. Makes a world of difference. And something we could define as a "miracle" of simplicity! Joe Jenkins "Humanure" book should be an obligatory reading! Something from where the Bill Gates foundation could get a couple of very useful tips. Instead of spending millions with ridiculous high tech "inventions". That don't stand a chance on a third world environment!

Is it safe to use humanure on trees grown for chop-n-drop put into food gardens?

@alexriddles492 5 лет назад

I found a copy of the Humanure Handbook as a PDF online. The book says it is safe for food crops as long as the compost process is managed so that the compost is all heated to a high temperature. In a compost pile this is typically about 150 F. Then it was aged for a period of time. If I remember correctly it was aged 2 years before use.

@fuckfannyfiddlefart 5 лет назад

I use a hot compost or wait two years, it important to balance the inputs, not to have just loads of poop!

@breunorboi 5 лет назад

The Humanure Handbook web site offers a free online version with all details, so long as your pile reaches 114F+ for a week or higher temps for less time, then all possible human pathogens are killed off. If you aren't depositing infected waste then even less risks overall. Then it's just a matter of time to break everything down into plant-available nutrients. Once composted it can go right into your food garden or anywhere else; just use a thermometer and make sure you are reaching the proper temps per the book.

@nothingmuch2023 Месяц назад

A standard toilet in Sweden uses 12 L per flush for very old toilets, 2-4 L for a small flush or a big flush on modern toilets. 30 000 L /year is 30 000 / 365, so roughly 82 L / day. If you're flushing a toilet 7-40 times per day per person, you've got bigger problems than water consumption. I am all for better toilets, but let's keep things in proper context, shall we? Using drinking water to flush toilets is absurd, but so is the exaggerations that make people not believe real true facts about permaculture.

Why only trees?

@TRAM1N 5 лет назад

Astrank, when dealing with human manure there is a possibility of dealing with diseases that might affect people if it comes in contact with food. This risk is minimized by the way in which the toilets are built and work, but then there's the extra layer of security, which lowers the risk to zero. You only use it on non-edible trees and that settles it!

@stropharia. 5 лет назад

@@wyattbottorff2473 Sure, I get you. In the wild, waste is typically dispersed. In this setup, the waste of many people is heading to one place: a reed bed (not sure why you think it's not...). I'm not afraid of humanure, but I put efforts into keeping blackwater out of my graywater systems. This seems prudent to me, but as always I have much to learn.

@breunorboi 5 лет назад

A urine diverter would be much better in this setup, so it's not running through the feces before going into the graywater flow, as it then becomes blackwater waste and has the chance (albeit low) of increased chance of disease. Plus as the barrel fills up, that urine takes longer to drain through, so increased smell is still possible, and relies on solar powered fans (plus batteries to power the fans at night? Or just more smell at night?) Having used the Humanure system which is far cheaper and odor free indoors, I prefer that. But I can see how this setup is designed as part of a demonstration for getting it implemented for more public use.

@ExtremePrepper 5 лет назад

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.

@ricos1497 5 лет назад

Why not just place directly onto the base of your fruit and nut trees? Given that the fruit and nuts don't touch the soil, there would be no issue. Alternatively, why not grow some non-productive trees that provide other uses?

@ExtremePrepper 5 лет назад

@@ricos1497 I thought about base of fruit trees, but then realized most of the fruit falls to ground . . . most of our stuff you shake the trees, and what is ripe falls to ground. Maybe as you suggest, planting some timber trees and using there.

@@ExtremePrepper To be honest, if it's for your own use I wouldn't concern yourself too much. A quick wash would probably do it. Bearing in mind, most people in the Western world eat heavily medicated animal's meat, with large amounts of chemicals on their fruit and veg, so a little bit of humanure won't do any harm!

@@ricos1497 I know. The think I worry is Heb B and things like that are rampant in Africa, and the composting toilet is used by the workers, hence not sure what type of contaminants might be in the starting material. Tough thing to know what to do.

@ricos1497 5 лет назад

@@ExtremePrepper I would definitely only use on trees for wood or other uses or boundary hedging then. If there is any danger at all, it's probably not worth the risk. If it was a more controlled composting system that guaranteed certain temperatures that definitely killed off all pathogens then you'd feel safer I suppose, but with these types of homemade system there is a trade-off between ease of build and maintenance and safety. Good luck to you though!

@Juno_Beach 4 года назад

so what we recycle water every single hour how do you think they manage waste on submarines and space shuttles ... water usage is irrelevant

@dodopson3211 3 года назад

Whilst I agree that the usage is irrelevant; how it's recycled is very much relevant. I just finished reading a report about sewage treatment in my own country (the netherlands) and because the same system also "processes" chemical waste it results in the sewage sludge becoming contaminated with lead, arsenic, and many other things that I don't quite know in English, which results in quite the toxic mess that can only be disposed of as chemical waste. In addition to that problem there's many places where the sewer can outflow into nature without checks if it's clean enough; resulting in contaminated ground water and the likes. The sewers in my country are very much an ecological disaster, although hardly anybody here knows this. For example 30% of ringed robs in the Baltic Sea have become sterile due to polychlorinated biphenyl contamination! I know my drinking water is Still contaminated with 1,4dioxane due to chemical disposal in the 1960s. None of this would've happened if we are more careful with our (factories) wastestreams. So why add more waste (water) to a system that's already overtaxed and so old it's leaking in various places? Although our drinking net is also hopelessly old; my water still runs through asbestos pipes!! 🙄 so much for the "clean drinking water" my country likes to present.

@crpth1 3 года назад

@breunorboi 5 лет назад

There is almost no dust in actual "sawdust", the sawdust that comes from a properly sharpened chainsaw is actual pretty chunky stuff. Also the sawdust or other cover material shouldn't be bone dry- Joe Jenkins mentions in the Humanure Handbook that if your sawdust is really dry, to leave it out in the weather so it gets a bit wet, as that will help it as a cover material. I've been to sites using sawdust as a cover material, with plenty of women using it, and nobody has had issues with "dust intrusions".
