master g o, a new delhi, his organization hosts a school for children of untouchables. everything is devoted to showing that excrement has value, that it can be used to make gas for cooking. for lighting, for feeding plants. dr. patrick wants to convince his fellow citizens, the toilets are desirable space. and then you should have one at home rather than defecating outdoors. he has even created a toilet museum for business, which generates the money for dr. paddock. organization is public paid toilets, thousands of which are spread all over india employing more than $35000.00 people. his even creating the taj mahal of public urinals. all this so that the hindu culture of hating excrement no longer hinders toilet adoption. in this matter,

doctor paddock inspired prime minister there, rend ramadi. a campaign is called swash by that. which means clean india mission for it emblem it uses gand, his little round glasses been not at all given. it's an unprecedented construction effort. tens of millions of rudimentary dry toilets are being built all over india and not at all, but it's also a massive communications campaign. giovanna will be on a prime minister, was filmed, sweeping streets and inaugurating toiletry. if you change nothing, nothing will change. a bollywood movie was even made about a woman who doesn't want to marry her fiance if he doesn't have home latrines. are you gonna do? isaac euclid, dodger, melbourne, idea. age of i. what i got to i me to the batch on the island. the law of mom by

became the face of toilets. mother. yup. oh. so cha about what? artificial chuckled. it's about converting a nation to defecating in a whole and i bought a dog the photo, bobby martin, bob taylor. and 5 years later on october, the 2nd 2019 on gand is a 150. his birthday, marin dra moody once again addressed his people and the world. he announced that no one deviated outside any more. oh my god, all thing i did, i did. oh, i got done, john, i got arrested doug. i saw donna minima. yes, we've got busy with the united nations, the n g o z bill gates. everyone pretended to believe that so as not to upset the

world's biggest democracy in india, their promise and the delivery are not the same. do they owe the 100 and then 1000000 by let it is anybody guess whether it is 50000000 or 30000000 or 80000000? we do not know. i think the only thing we can know is that the low bang has promised to this review, though. 1000000000 dollar through india if they can prove that the buy let it been use and today i think there has still not yet distribute that. the $3000000000.00 what to serve his own political agenda. and therein, remote, he chose to massively subsidize latrines which often went on used to this day in india, paperless till deviating by the side of the road. ah,

it will sit on the back is i, we embarked on this adventure with the gates foundation to discover the code of bad odors to see what we could do to find a scientific solution for 1st time toilet uses in china. india and other places. yeah, yeah, i see. so we did some science together for the adventure lasted several years, a prison that in 4 months german issues, researches traveled to collect fecal owed as at the source in latrines in india, kenya, uganda and south africa. from this fitted around the world trip and they brought back the conviction that beyond climatic and food specificities, there was a combination of 5 compounds which cleverly balanced could reproduce the exact odo of excrement. yes, this precious nose,

which generally designs the essences of our luxury perfumes has been assigned to the approval of feces, no taste and smell a tied to emotions. so could we bring positive emotions to the poorest among us, who lack access to toilets, but sadly dre the technique produced a powder to throw in the bowl, a spray and a hanging air freshener, and is already sold in several african and asian countries. it was tested in india in the city of pone where a start up is developing a new toilet bus model exclusively for women. that's a fundamental aspect revealed by this toilet revolution. lack of access, sanitation has a much greater impact on women that on men and belgium. marino scotia, in a world mostly made up of male engineers and technicians is an activist for this

cause. long day the law have access to toilets and hygiene for women is definitely the central issue in this conversation said this, it says it. yeah. for some women, it might mean getting up very early, and before the rest of the family, i want to plan to go and relieve themselves in the field next to their house or village, or waiting to go late at night. why don't, why, let's what her dollars, family, song peak that's dangerous snowflakes. anything else they say, we know it is lead and still leads to sexual violence may yet more problem, but also to feminine hygiene problems. infections do look was now that's why solutions like the bosses of really great because they have diapers, stations are yet information about aids, information about how to use feminine hygiene products, assistance and support for women and their personal hygiene. poly fan, don't you get none of that out in a field? genuinely fam, no, no, he and that's, and then,

nor can you wash your hands and when a sample model. and as we have all learned in recent months by lima, that can create major health problems that prima monte p. news, wasa, kaylee, gore, problem. this'll be a durbin, a south african city, with 4000000 inhabitants by the indian ocean, is playing a crucial role in the ongoing toilet revolution. because of the endemic drought in south africa. but also more surprisingly, because of the end of apartheid, martinez was to prepare for the new south africa. and as you know, the parties you had, you had a central city which was mainly what people surrounded by a sea of poverty, which was mainly african people. many of whom had no services from 1996 until 2000 . it was easy to motivate for money for water because that was the big issue. but

we started to realize that just bringing water to families was causing another problem and public health problem. because then there was crating sewage and the surge was just running through the houses and causing problems. and then in, in 2002 we had a color outbreak and that changed everything. suddenly the politicians said, we need sanitation with neil mccloud at the helm. the municipality of durban has become a pioneer in the separation of urine and fecal matter to save water. it's also testing alternative solutions to the western flush toilet and waterborne sewage system. a research group at the university of choir zulu natal is neal macleods experimental branch dead. naturally one day bill gates came across neil mccloud, his pollution research group, and the crazy sanitation history of durban. and we got that phone call in december 2000 and nod please be at the hilton at 6 o'clock in the morning. there's somebody

coming to see you and you can tell anybody at i thought it was going to be bill gates his father. and. busy abduct bill gates had a new you know what you want to show me? why you keep up your deposit off that they did the rug sector. and i said, well, you know, balance which it was, i don't need your money. i need your interests. and we took him out, chris buckley came with me and we showed him what we were doing. and our partnership was evolving and he went back and he started investing his annotation and the rest was history. i mean, he started the reinvent the toilet challenge and we became the engineering field test center. yeah. for all the work and that's continued on as, as we've made all the advances. so when the reinvent the toilet competition was launched by the bill and melinda gates foundation, durban, and it's hundreds of shanty towns were chosen to test the competing toilets designed by chinese american and swiss universities. there were technical

challenges, but there was socio logical ones too. among the 10 systems tested in the shanty towns of durban, a chinese company had a spectacular failure. and china, you don't, through the toilet paper in the bow. in south africa, you do very quickly, their brand new system broke down in dublin and it took days to get it back in service. we had a lot of sledge build up. so those are things that we had to deal with on the ground and figure out how to, how to solve and, and ultimately, you know, it's sort of came to realization that the way that the process was design just wasn't applicable to south africa. yeah, that is one of the challenges when bringing in a system from another country and bringing it into a developing country where the municipalities generally did not have the skills or the capacity to maintain and operate the systems. say yeah, it is something that has to be looked at when you're bringing in

a new technology. are you able to maintain it? are you able to operate? do you have the necessary manpower to do it? ah, hello. i'm bill gates, chairman of microsoft. in this video, you're going to see the future. bill gates has a major technological bent. you can't really reproach him for that back. is that bent, which has made him one of the richest men in the world from selling computer operating systems to most of us windows environment? when he decided to reinvent the toilet, said that it could be used even in countries without waterborne sewer systems. bill gates, his geeky side naturally, came out the universities which worked for him, a developing chemical solutions reactors to destroy the bacteria in fecal matter. electrolysis based treatment was their toilets end up looking like spaceships. with highs the loft, she's done,

the injected air pushes the fecal matter into the reactor eyes and the, the aqua has been the valve closes or, and the reaction occurs. they act through its combustion. the fact we, i know m detect the fecal matter is then heated to between 40600 degrees celsius on look at about 300 bars of pressure fell by i wound up bar. i think originally bill gates were thinking in this way. he thought of when he was young, a compute the feels at silver, a rooms, they'll be able only to compute a little bit of information today. their computing power on our cell phone is able to do the job of very, very big i, b, m, compute the long of goal. therefore, his belief is when technology can be introduced, then everything becomes smaller and smaller. the only difference between the

computer and us is that the computer is in bytes, and you can just keep on growing the bytes without growing the size. whereas the put it in apple, you cannot digitize. hope you will always physically has that 200 gram. every time, well i brought a little exhibit here. ah, this is a container of human b thies. i dana think once in a speech i released mosquitoes. this we're gonna keep in the char ah, ah, but in i think even though it's very stark. ah, it's good to be reminded. ah, dead inside there could be over 200000000. rhoda virus particles 20000000000 she gallia yellow bacteria,

and 800000 parasitic were makes which you got a little animation in november 2018. when bill gates placed a jar full of fecal matter on the podium at his conference at the re invented toilet expo in beijing, the billionaire prove that he is a master of communications. he achieves the unthinkable putting toilets on the global agenda. he also successfully imposed a new narrative that excrement can be profitable if it's at the heart of new industries which produce energy and fertilizes. the toilet board coalition was built on the dream of being able to transform poor people's poop into money. one of the main ideas behind the toilet board coalition is that the collection of fecal matter in poor countries will be enough to create sufficient energy, like bio gas or electricity to finance the whole sanitation system to become tighter and beijing,

everything seemed to be going great so universities were proudly presenting their new toilet solutions in you and bill gates announced that the technology that his foundation had financed are ready to be adopted by the market. here. our goal is to create a, a multi $1000000000.00 business opportunity. all that at some point is getting by without any sort of philanthropic grant money that it really just a balls are into companies competing to buy the best product using these new paradigm. 3 years later, in a world in which we are questioning our development models, priorities have changed. the high per technological solutions advocated by bill gates are having a hard time finding a foothold in the real world. they're probably too costly and they don't challenge all waste management. it was an afternoon like any other biologist. felipe malaysia

knows home in a village in the swiss alpine foothills. there he's testing experimental toilet models which use nature, particularly earthworms, for fecal matter treatment solutions. on that compet won't be able to contact i, vic, we've completely lost touch with the side on proximity of our excrement lap hawks. him, it did not come off at that juncture, we excrete it. we flush on an old, disappears toward this, but it's gone. the i think the on the thing, we don't know what happens to it or not, but there are no risks. was no odors good of what? when you see a feel was big enough to feed a cow throughout the year. i mean, there's 500 killers of meat on that cow and 3 tons of earthworms right there under its cache. yet, quad done the vet that there. it's the earth worms that are hard at work on of idea

worms, our fire reactors, all the gaudy blue doctor. you don't, we consider even the shape prevail? 3rd there long intestine and newly more come the low even more so than us that just packed in a thin skin embody, didn't put it cushion to put their even better by reactors than we are. yolk act up and then the so much so this fecal matter inhabited and colonized by mushrooms and earth worms in your becomes edible again for one fact the when you commit to eat what they excrete that 4 times or 5 times it gap for sulfur filipe malaysian who uses earth worms in his home made toilets to kill bacteria and render the fecal matter harmless. he relieves himself in a tube to give his vegetables the good nutrients contained in his urine. oh, you might think that this professor calculus of the restroom, this earth worm fanatic isn't

a very serious person and that he's not going to so the global toilet problem. ah, then phillipe invited us to follow him to geneva. ah, this is a building in the heart of the city it's residence decided to develop a more ecological sanitation system, which could re inject waste water into a very low volume flush toilets. so they called felipe malaysia knew who rounded up his worms it welcome what you were. what do you envision already that far it was just in your house, but now it's for a 100 people then for 350 and then law street. but she,

by the buildings with $300.00 people, would be pretty good on there after that. the next thing the neighbourhood could do this in a whole neighborhood. if you look at these lovely earthworms, your people, a nice big bunch of them, are you it's a big pool in the buildings court yard full of straw excrement and earth worms. a giant filter which makes it possible to treat organic matter. and even a lot of chemicals, the earth, worms eat, eliminate, and re ingest everything dangerous, purifying it the combust can then safely be used to fertilize the gardens. it doesn't smell bad at most. there's a slight smell of humus wafting in the pit. oh, it, mcdonald, there is maintenance, right? if it's in a city, don't you have to take some of that out from time to time, which is the level not just the with no, everything is transformed off of it. oh, here we have the decomposition of all component was the whole, the sugar polymer,

sickle into carbon dioxide and water through this affair just perform windows and all of the residual minerals are flushed out with the excess water grill of it. in fact, i've ethnic food, it said legal latonya. so when you see this hyper modern building in central geneva, it's 38 dwellings. it's a $140.00 residence. you'd never imagine that there are millions of worms on cleanup duty in the courtyard. that's good said the hotel goal is to get water. that's clean isn't what comes out of the treatment plant or at least it's clean but cleaner? if possible, it's not hard to achieve because water from treatment grants isn't very clean. that's all. depends on the thorpe up up. it's that he counted on rapidly digested through, injecting oxygen get here, but coach helps develop bacteria that consume residual sugars effectively. that's all easy to digest, isaac, to scare fatty luxury or at the 1st stage of waste water treatment. this involves

removing the large waste that comes in from the sewers. if we find tree branches, sanitary wipes, all kinds of waste. it's vital that we remove it from the water before it gets treated at 1st, you focus on the p. poop side of this story. of n, you realize that it's about something else entirely. this sanitation revolution challenges our entire waste management system because all sorts of things end up in our treatment plants. i was just as quick and easy or, you know, what is waste water? is okey san gina. it's the water generated by our household activities. sun toilet water earlier gray water from our daily activities activity you can keep, you could, you could see it's also the water use for artist law and industrial purposes. only . there's one to latina. lastly, you know it's rainwater, which washes the air and the city and then flows into the collector's. it's all and

that was one or liquidity la cruz's it to. so i always let it have the credible to where the activated sledge treatment stage. it removes nitrogen and phosphorus from the water, sorta it, oh, how do we do it on forever? again, we use nature. we cultivate the naturally occurring bacteria in the water. of course, in addition to feces, waste water carries a whole bunch of chemical products called micro pollutants. and they're much harder to treat but any hopeful your cool about we are on the micro pollutants in our sludge. and this is the problem if they come from many different sources and acquisition, our cell us in particular. nor was yeah perfectly. what you were saying is quite right, lost over when we go about our business. so last, when we're washing the dishes or washing her hair, when we'd our garden remove moss from our roof, et cetera, we're not, we're not, none of those activities lead us to not where you are without

a realizing it exceeded fish and to use many compound songs all mentally and multiple components. how many today due to non bush molecules, workem foyzey, could i get the clean the bathroom go? all stuck with a nasty, has job in the house naked guns that total action vanish. try it. see total action vanish, lifts off water stains, disinfect bleachers. he believes it's true that for decades we were encouraged to throw as many chemicals as possible into our toilet bows, to eradicate the slightest bacterium jobs right under the rim and leaving the problem. the makeup of the problem is that micro pollutants are getting worse as human kind invent new compounds. when i'm produces new compounds without having studied the hom, they might do to human health of the environment and they look are backed up unless you meet. they pour latso, do men april says to love you all were creating an increasingly serious problem. don't recall, not only of these synthetic compounds not removed in treatment plans and also mon

this'll. they also accumulate in places where we really don't want them to approve it both sac remotely. i dissolved waldrook rapidly to can suck at the outset of this toilet revolution stemmed from the idea that we have to give sanitary facilities to those who don't yet have any. it's also about giving developing countries, small treatment plans to avoid investing colossal sums for waterborne sewage systems and giant treatment plans, especially in south africa where yeah, we don't have that the space. so i think that, you know, the facilities to put in more big large, you know, central waste water treatment works. and it makes more sense, economically and also environmentally to have on site sanitation treatment or decentralized and treatment systems. rather than putting in extensive, you know, piping cetera, to, to take everything to a central place, it's much better to treat it as source. and if you can take that in and produce

something useful out of it, that's, that's even better at the truth is the new toilets, new wastewater treatment models also sold our 1st world problems. decentralization treatment in each neighborhood or each residence could enable us to better control what we release into nature. and maybe it would make us more responsible i really believe that the for onsite treatment, the centralized treatment, we can really improve the overall sanitation system. i there will always be a place for centralized systems, definitely, but not for every location. so we, we can also, we also have to rethink the water use. so now we have to water supply and it's, it's such a big achievement that we have fresh water drinking water supply by pipes. but do we really need drinking water for toilet flushing? and we really need 50 lettuce per person per day for tight flushing. we don't need

that, so we can, we can actually recycle water. so in large buildings we can treat the gray water, so that's water from the bathroom and from the kitchen and will not the toilet water. we connected 3, there are the easily to reuse it for toilet flush. we should do that. we should explore new options. mm hm. so it's not just about the little boys or little girls room for the last 10 years. this broad, re think of the way in which we manage our most basic waste is a definite point of no return around the world. the vast majority of waste water, more than 80 percent goes untreated, how stool are urine contribute to the over 30 lies ation of the oceans to excessive al gay growth until the us fixation of the sea floor. the way in which we manage our excrement isn't insignificant. it's the very heart of life.

fecal matter and urine have always fed the ground which feeds us back when fear of disease in cities lead us to banish our waste. as far away as possible, we replaced natural fertilizers with chemical fertilizers on the moon. who knew that had thought when we dr. giving back to the soil one, we took out of it because i started living in cities. and it was too costly to return to the earth things which should be returned to the earth that we created. instability helped us out as a cuba, but we might not all end up with earth worms at home to eat our excrement. this idea that faces should return to the ground, but we can't content ourselves with getting rid of these substances without transforming them. and re integrating them into the life cycle. will certainly be

the foundation for the launch of the upcoming toilet revolution. doesn't go jose beaumont well, that doesn't go as a verbal oh, i will look at more. no more at home. that room with blue me ah, a teachers are searching for their students in a fatherland, brazil. many children have not contacted the school. a consequence of the school closures during the pandemic. the teachers are campaigning for them to return
