zayed our private lives through surveillance. opaque, secretive. what's true? what's vague? it doesn't matter. the only criteria is walked. we'll hook people up. we shed light on the opaque worlds who's behind her benefits. and why are they a threat to us all opaque worlds this week on d. w with cities and communities are growing faster? often their research systems gone to keep them whether it's from humans, animals, or industry. what we leave behind is a burden on people and the environment on eco,

and yesterday we meet individuals with bright ideas, a handling whist, hello, and welcome. i'm son of that. i hope we start with the basics, functioning toilets, a more than a convenience there. weitel to public help about a quarter of indian population lives without regular access to standard to the facilities. one social enterprises working to change that with smart public toilets that improve hygiene and restore dignity to the open port. ah, philly and vandalized, public toilets in a slum of 40 the bad in northern india. the cities way system has buckled under explosive population growth, colony resident manascale, my seas. there are lots of toilets here, but many more are needed. save a landline,

that's no sewage land in the colony that so people dig holes and create toilets at home. it's live over here. but the people who can't afford that go out dos of difficulty either without c, which pipes or solid waste management. fiegel waste ends up in bonds and water bodies around the colony. tap for to here is so contaminated residents frequently fall, ill, waive i still have kids here are constantly suffering from stomach aches and diarrhea, my grandmother, and now that the heat is so severe, the water problems are worse in 2014. the un identified india as the country with the highest number of people practicing opened education. that same year, the government launched such bad admission or clean india mission. since then, more than a 100000000 toilets have been installed across the country. experts say to day, only one percent of the urban population and 20 percent in rural areas. still decades in the open. a navy, in slum areas,

we have installed community toilets at many locations. so the problem is that people living there don't use them properly to use an eco buttons, toyota. the have to happen with our little bulbs get stolen. fetal seats get broken and that's get stolen. people break the wash recently. we don't know why people do these things, but these are the issues be face that make toilet maintenance difficult. it is a problem. the problem of toilet maintenance isn't confined to oven slumps. it also affects people who travel or walk on routes as kashmiri gate, a bustling metal stop in delhi, there is a clean and smart alternative. the sanitation center was built by the company, got toilets, and installed in partnership with the deli metro real corporation. now how coil is in charge of the project?

my unc meta is the company, c e o and co founder. they show us why the thing this facility can make a difference. they are separate cubicles for women and men, as well as for transgender and disabled customers. we are using stainless steel because though it's indestructible, as you know, this is a high football video. so a lot of fob, i mean people, government, i do will do some vandalism and people on break this oh, so before entering the toilet we have indicator lights here which you can check and all know whether the toilets are occupied or not. oh, we have vall send surveys, operations deals, so after every usage of flush, we'll get a trigger, even the basins tyrol since a best a. so you don't need to touch anything to a washer. hence, the company monitors data like user numbers via an app centers, middle air quality. if values dip, stuff are dispatched to pin up about

800 people use this facility every day. one visit costs 5 rupees, about half of your cent i was in math. i use at 2 to 3 times a week, but because these toilets are clean and safe. yeah. the problem, li, oh yeah, for safety via xander. unlike government on public toilets, the private ones are clean the use of more basic words are free of charge. they are financed by central or local government bodies, or companies with social responsibility programs. god sees these doyle itself, some 60000 slum residents across india. there equipped with wash basins ventilation and also rely on sensor technology to flush automatically we will not clearly depending on or user to either flush the dollar and even the

cleaning self to come in and clean the toilet. so the toilet was managing all by itself. so self cleaning and sell flushing envelop good man 40 the bad 50 are all set. deal with these spends her days selling flowers on the pavement from morning to night. finding the clean, usable public toilet. she tells us has always been a challenge. up until now. she's had no choice but to walk hoffer kilometer to get to one. today she's using a smart toilet for the 1st time, recently installed a stone's throw from where she walks out of the ha ha. and now there are no issues like there were before. no stench, they're clean and there's water too. of course i'm happy now that i can use these toilets. the fiegel sludge is treated onsite in digester tanks and don't into liquid for the laser. and in areas where grid connectivity is scarce, the toilets are solar powered. the company sees it installed more than

2100 of its toilets nationwide catering to 230000 people from low income communities. people like flour, cello sat there would be it's a service that's made her long workday a little easier. while human excrement is not something generally viewed as useful, but in mexico it's been employed as an effective organic fertilizer. since ancient times we visited farmstead a composting it to grow veritable gardens of eden. yes, all last long. thomas leah nueva is so pleased with the day's harvest that he breaks into sung as he delivers the sample for the kitchen. their laughter are these jo. yes. jo, his wife liliana, randolph will use the to prepare lunch. after working our doors, every one is hung, every one is hungry. and thank the

water for watering. the plants was the compost for feeding them. kilogram. the net that composite was made from human excrement, all perfectly normal farmer, thomas villanueva and his family. on the edge of the small mexican town of tampa, takes law in the state of mexico. the all entirely farm grows, fruits and vegetables. everything here is fertilized, exclusively with homemade human dung. no such was gonna so complete in the cycle chic lord comes from me or if it's digested and excrete out of whatever. so that he castiano that he had a process of composting allows us to give back to the soil what we took from anchor bold barrel at vieira lockerbie. so we complete the cycle and live continues the lobby, that a c they eat their own vegetables, but they also saw them at markets. all plants need nutrients to grow, especially in nitrogen and phosphorus. all in t ali is a fully organic farm,

and artificial fertilizes are banned. thomas via new eva says they're expensive and bad for the soil. so he and his team invest a lot of time and effort, collecting excrement from dry toilets, mixing it with natural ingredients like stone powder or straw to transform it into a rich compost over a number of months. the activity of bacteria leads to high temperatures during compositing. that heat kills any pathogens, elk, our guy, philip, the name of said, miss compost here is now ready yet, and it's most pleasant. like fertile soil, be of a verity. they used to grow various types of cabbage, beetroot broccoli, fruit, and a whole lot more. lead come to the small town of aucker to peck in the state of maryland. here, architect says are, and your van has also looked at ways of recycling feces. if somebody can look upon

the earth, this is an ecological neighbourhood that i set up more than 20 years ago. i wanted to show that homes can use dry toys and not pollute any water knock on seminary light. in other words, toilets that divert the urine away from the feces and that are not flushed with water. these toilets are not connected to the sewage system, either number with here and lands in the front here. hope at the back. just add a bit of soil. it is a little and that's it. either a lot of raw sewage in mexico flows directly into lakes rivers and the see something says are on your bay, finds outrageous. he believes dry toilets of the solution and gives workshops, teaching people how to build and use them. look at your stuff in the ethan trickle . but what i'm doing is reviving the knowledge and understanding of water that our

ancestors had. if they didn't see excrement as something dirty, but it's something that meets to be returned to the earth's window. ah, this ancestors used human feces and other organic ways to develop fertile islands known as channel pass used for growing crops. in wetland areas they've been used in mexico since ancient times on one she nampa on the edge of mexico city. lucio was so bianca wants to keep that heritage a line. latino passes from oil of book that she numbers are one rare example of how we humans have helped to promote life and biodiversity. so they're a very powerful example of how we can live in harmony with nature. not one year, colon up with alice. he runs a regenerative farming project called ad cut yetta. the idea is to grow organic, produce working as closely as possible with nature. the produce is then sold to restaurants in mexico, cities. he no longer need to give back to the earth. what we've received the ship

of food. otherwise you get an imbalance leading to pests and depleted soil. the summit of efficiency us to feed the plans properly. you need to return all that's left over, back to the soil, and some follows this polish back to the old in t ali organic fun. thomas via new age as customers know how his vegetables are grown and they whole heartedly approve. la got got in illness. obscene no pump has a bad image in our society, them both. but we know that this composting process makes it perfectly hygenic than amazon gravel garcia. and we always like to say as that with a point, you never lose a harvest and but i go now must get going. yet michael said chuck as at the end of a cycle of giving and taking eating. and dick squeezing something that triggers revolves and elsewhere is seen here as the most natural thing in the world.

why convulsing human excrement may be a novel concept to some animal dung is widely used in for production. but when communities live in close quarters with livestock, large amounts of manure are dangerous. the people's health and the environment. a startup in india south has come to the rescue. one willis that now don's done into energy. cows are central to the livelihoods of people in the village of roger, roger, purim and family modesty, a village with farmland, husbands, solider. but the push of arbin grew from the state capitol janai roughly a 3rd of its 900 households. still keep livestock and sheds next to their homes and rely on the milk to support the families. but all those goes great. massive amone's manure village resident parker, you saw me says it's a problem for the community, and it's ground water. in the la maya, the pl de la rezani and lots of called angus dumped into the back. it goes into the

many open drains in clarkston, which stops terrain water from floating through. this causes disease and mosquito infestation fever and vomiting at all. for coleman, we wanted the government to do some to help my wi fi router. the authorities turn to karen agger was for help the former banker and as a startup carbon loot and wise industrial plant operators, educational institutions, and authorities on all aspects of waste management. they approached us and we had given them our presentation on how this waste can be used in a very positive way for the electrification of felonies. the authorities awarded to start up a contract to build a bio, guest blonde and the public sector and rested equivalent of almost 700000 years in it. the blonde on processes between $1.00 and

$1.00 half, dozens of common miller each day. a huge relief for the dairy farmers. community leaders say that disposing of the dung is no longer a problem. it will rudy with on our way to santa fe or little and then the thought be now collect common load from each house and process into out i guess it out of the gas agenda. age can be used for cooking and electricity radiates, is stored in a generic tunnel either monday and i'm a elect, as didn't paula's $1250.00 street lights each night is one of the gonna lemons out there to learn a little bit on the community used to pay up to 1700 euros the electricity. now it cost about a 3rd less pollution levels in the local water have also gone down the race from the bogus blonde. and don is

a top quality for delighted high nitrogen compound. local farmers are more than happy to take it gamino isn't the only type of race that can be used to generate electricity. carbon loops recently put a blonde into operation in another municipality that addresses food waste and the currently $1.00 tons of grace from the market, including vegetable rays and hotel food which is collected and brought to this facility. again, we are processing it turned out by a gas plant lead and converting it into electricity. both by august, plants have the same effect, the protect the environment, and increase people's quality of life by producing energy and the former rice farmer. a peculiar sammy now works for the bio guess blonde in his community.

the pilot now and the topic isn't manure. it's much easier. the fashion industry produces it every year, but a lot of it is discarded because it's either unused on damaged to bank of based on the panels are working to keep dead stock fabric out of the dumb with a website that gives materials a new lease on life banks full of fabric that are like new but surplus to little to create a new collection, but to valuable to shred. the store room of tama one village ions garment factory is jam packed with them. over production is just part of the business model . every account, let me order the family for each particular order. we have to always on an expire presentation. just to be sure that we have enough fact me if the defect happen, or if buyer decide to change some quantity off eyes,

then we have enough to colbert to hold quantity. the young entrepreneur can't do much to change that. still for years, she looked for ways to solve her surplus fabric problem. then, 5 years ago, friends introduced her to financial manager. aman paule, who won on a man with a mission. i wanted to make a change in terms of waste management. and given that we are into digital ish, i think the best way to now manage to list and make it into a scalable business is through the internet. in 2018 in bangkok they founded more loop and online platform for fabric remnants of symbol yet clever concept. we're like a, b and b fossa fabric. so these quality fabric, we was sauce them from different warehouses and then they would give us the data

off death, abby and a sample. and then we basically put these on to the internet so that people can come and browse and shop online. but the business got off to a rocky start. few believed anyone could produce quality fashions from fabric remnants. after 4 months, the founders were ready to throw in the towel. but then they had the bright idea of creating their own collection. wendy upon deals into the t shirt and easier to danny, have a sense of quality than delay when they pass. if they showed off their t shirts at a trade show and sold out in just 2 days from then on, things went quickly at 1st, just 5 factories sold their surplus fabric to more loop. now, more than 70 textile producers and to remnants into the database,

the selection is large enough to attract corporate clients. more luke now produces tailor made products for 150 companies, like insurance firms, allianz. oh wow. i think it makes sense. instead of producing the new fabric, why don't we just use whatever that already available? and, and, and, and that's good because i, it means that i, you also help all the factory are in the country. asheville, paula, she's ordered, 18000 polo shirts. masks and baseball caps all with the same design. i. huh. that's a big challenge for the startup. oh yeah. we have to make and match with many on different type the different test on fact make because the quantity in to be an one left all of us me could affect the quantity yet major clients

overlooked these little differences to show their green credit as an additional service more loop calculates how much c o 2 they've saved, depending on the color we've and production method of the chosen material. i mean, it's not just big companies who make purchases over more loop. so does young designer t i e dot own blue runner, won all the bags and clothes. the boutique artist creates for her label. marianna z um are one of a kind. she adapt sir ideas to the materials, not the other way around less. i only can make on her for now. my pin gap can oh, it's more like giving new life to unused fabric like my why. so it doesn't feel like 2nd hand fabrics appointment and the customer's feel the same lesson. can he that and been can, it's just re purposing he and giving more value to the fabric. why that,

that can time will a hassle pam aqua lisa. hi, lisa. it's a win win situation. to date, more loop has saved some 500 tons of carbon dioxide. the equivalent of the c o 2 emitted during 5000000 kilometers of car travel. but that's still not enough to satisfy its founders. you want to be to pass off the global transition to a circular clammy. we want to play that part and we want to be part of making this new equilibrium a reality. there long term goal is to keep growing and get 500 textile firms putting fabric into the more loop. and they plan to offer more of their own products, along with t shirts, masks and p, p. now, more loops concept aims to prevent new waste. but or junk is often the legacy that simply ignored over the french capital batteries. an 11 year old single handedly

tackling trash in the re will sim dredging up relics from its depth on any given saturday morning, 11 year old rafael is likely to be out doing what he likes, best fishing, but not in a conventional way. let us only more in thunder. this is a magnet that can lift up to one ton almost immediately. i fail together with his father strikes anything, shopping trolley chicken was i will i will do it in good, unique. i started doing this because i thought it would be fun to do that, but it quickly became some kind of hobby or rather a job. now we are doing this almost every weekend. we have to do it as other adults are doing nothing the built open. so that will be all working for you. i shall hit

brunt of the waist adults produced to be and he understands that being conscious of how much waste we produce and taking action to transmute it is the need of the our, i'll see we'll get next week with an equally informative episode. good bye. and thanks for watching with, ah, with
