every price of kenya, 2 in the country like to keep taking on the powers that be they risk everything, john dunbar, mit activists, journalists, and politicians living in exile. they will em tortured the live for their mission. what drives them? people need to know what is happening there are ceilings, guardians of truth watch now on youtube. d. w documentary thing oh hello. i'm sorry to cut the lady and sorry me to remove this mask. not a huge fan of it anyway. keep keeps winning my makeup. but what options do we have?

look at all of this construction. dusted on my house anyway, i'm sorry, got the lady and you're watching ego india. and today i will take you along with me to explore innovations that are offering improvements through the way we build, including how to deal with this annoying dust hand to my heart. if i could, i would go to the she gauge at least once every month and maybe also lived there between october and december because of the pollution. and maybe also man june because of the big heat. i mean, i can practically live this, but i feel more daily i than people who live near the capital region would share my sentiment. let me show you. this kid is a beautiful city located in the foothills of our him, aaliyah's, in and out mountain state, oregon, the beautiful, pristine ganges floor through here. and it is a popular we can get away for more delegates. i mean have given

a choice. no one would deny living here. i mean, also because delhi is a city of extremes, the heat wave del cold wave, and unbeatable pollution. the pollution here gets so bad that be we have it down for people who leave the city for a couple of months. the polluted months. it's quite a while you cation and i mean, one of the major reasons i cited for this pollution establish burning likely is for a couple of those months. but that is someone who has done this problem into a solution for the same problem. hook in on what it is, see for yourself. loop in the low lying mountains of education, locks me, see what swamis overseen construction on a hillside home for her family. and husband spartans will move year to skip the toxic air pollution that plagues delhi and it's greater metropolitan region. no, not the and c r. basically the idea is off for making my aim last feel more comfortable with respect all the unfortunate illnesses that you encounter in places

like n, sciatic cetera or in, or diabetes and pressure, et cetera for wanted to bring them to a place which was more peaceful and more connected to the the house is not just located in a beautiful city. it is also building materials that are easier on the and one and then conventional homes above all, with an alternative brick build, but it's makers as goblin negative. that is because it addresses one so, so the stifling the smog, the jokes deli, another indian cities during the winter. when farmer's daughter, there feels to clear them of crop residue and dine for their next sewing season. to tackle the problem. done johnny set out to dance dublin to had his source. the break, he named agreed combines grove vist like betty straw with the mineral binding since 2020 his company green gens has produced thousands of blocks that it says have

helped capture more than $130.00 tons of climate heating, carbon dioxide. so in the crop is growing, it is absorbing theatre from the atmosphere and it has basically embodying it. but if you leave it or become for the burn, the theater goes maggard, the atmosphere is especially the cobblins i could put in a nutshell. now we stop and then we take the crop residues, we mix it with a middle binders. 3rd, now it is chemically bonded within that concrete. and that is how we're actually able to, but the carbon cycle and put that theo, to ring to this mix. and because it has chemically bonded, it does not ever go back out at the atmosphere. the bricks are lightweight and easy to handle. they're also robust an offer better terminal solution than widely used clay bricks like these that make them a sturdy alternative for smaller scale buildings in a country that over the next 15 years, expect to see a continued construction boom. clean sort of needs to be fired under both 1000

degrees in degree to create good bricks. this is a high temperature. and of course, if you have such high temperatures, you usually need a lot of fuel. and most of that fuel is of course. so in fact, india is the 2nd largest producer of bricks you produce about 202260 1000000000 rick every year. and in terms of industry, it's the 3rd largest consumer of coal. so you can imagine how much of emissions i'm thinking because i grew greed doesn't just have the potential to come pollution caused by double burning, and clay killed the bricks and the factored by franchise partners who fills harvest residue from local font that generates extra income for farmers and got emissions from prosper, patient and logistics. so we broke helicopter to do they come monday to lose the common multiple formats, depending on how it has harvested. we filed them up here and you can see this tiny

hillock of fall by the straw here. and after that happens, the once we receive it here, the next thing that we do is we using a threshold machine. it's regular farm equipment that has been used since centuries . so we use that and we resize them, which of them up into smaller plot because once jump in. so this double is combined with a pit tended binder also made from agricultural residue. i'm not dr. byproduct of the steel manufacturing. this is a bad mix up into the go the crop record years and the flyers. and the most important competence with outward aggravate cannot be made, which is by so those are the bags of bind over manufactured and why is that in our own manufacturing? unit. half. and after mixing the greeting, molded and left to sun dry for a week, rise between $26.55 pounds each less than 60 euro cent. a single block equal the

size of $8.00 to $10.00. red clay breaks. that makes it a keeper option. that's all those multiple problems. one go to the vs gets reduced to double burning, as you said, gets reduced, heard. but have the fact that you're not. if you use such a material, you're not going for virgin material which have to be extracted on mind from earth . which is a good thing and forth, but has also the fact that it can trap godwin and put it into a lot of buildings, which gives me a way to sequester my goblin into my building, which is a wonderful idea that can leave me a call back and re she gauge civil, non busy locks. me see what swami. construction side. it is the 2nd house he has been using agra, green them on the come all it is very easy to work with.

first of all, one block because single conventional break much faster to work with. i do not have to use a lot of more thought either. let's see yet i have used only one block. that's the same size that it had been since i would have to do this big times, bigger than it saves me time to learn more about going, how technology and nature can come together and how we can be responsible to not only this. so i took the responsibility with the brick and other things that we are going to use in this place so that it is going to be more sustainable. and of course, give the opportunity for my family to be more close to the nature a home close to nature, built with a bridge that can be produced almost anywhere. laying the foundation for a built and bonded. and that is designed to protect our natural resources. ah,

feel is killing me environment. yeah. the same method that you are you dancing. * home, and even the back of this watch is middle si, stainless views, but still sucks because it is very damaging for the moment. i'm not saying this x spots are telling us, which means that every time you use any the made us feel your problem footprint goes on. damn this one. but there are some things that can be done to reduce the ad was in the back door feel on the environment. this is the metal that makes the modern world tick. imagine life without it. cars are captured electricity. but this one, the material that aligns are built around carry the dirty secret that nobody is talking about. the steel industry is responsible for jaw dropping,

8 percent of the wells, greenhouse gas pollution. and bizarrely, we're actually going to need a lot more of it to clean up our economies. so how can we make steal green and what's wrong with the industries favorite solutions? there are 2 reasons. the steel making process is so dirty. the 1st is purifying the iron or needed the steel by heating i annoy choco fires o mixing it with coca cola and big blast furnaces. you can extract pure iron from rock. that's like an oxygen atoms in the ion all fly off and bind with carbon atoms in the cold. what's left behind is essentially pure iron known as reduced ion and a whole load of c o 2. the 2nd reason steel suck said that it takes colossal amounts of energy to power this process. and most of that comes from you guessed it, burning coal. so what should still make is be doing right now, either gen hydrogen,

hydrogen to hydrogen, wanda's all, hodge, hydrogen as a gas and fuel that can be made cleanly with renewable energy. oh, much less clearly with fossil gas. if you reduce ion or with hydrogen, oxygen atoms no longer react with carbon atoms to make c o 2. instead, they react with hydrogen atoms to make a h 2. 0, the beauty about this concept is ah, yes. who needs a new production process? but as a byproduct, you have water instead of c o 2 and, and this is how we can make, ah, the steel making process time. what's the 2nd step of then feeding the purified iron into an electrical furnace? these devices meltdown scrapped steel or reduced ion with high currents of electricity that turn them into liquid state. and ideally, they would be running on electricity made from renewable energy. that's pretty much what swedish steel make a s as

a beaded when it delivered the wolf 1st batch of fossil free steel to comic of over europe. steel. make a betting that hydrogen will be the future of steel right now. it costs more to make it this way. but if gas prices stay high and carbon taxes rise, switching away from fossil fuels will become increasingly attracted from a business perspective too. but of course, using hydrogen to learned doesn't make steel, greek. it's a process with several layers, kind of feels like an onion. this is kaitlin's wallack, a steel analyst at the u. s. based non profit, global energy monitor. the 1st layer is to make sure your electric arc furnace unit is running completely on like green energy. but then you need to make sure that the reducing agent and the direct reduce iron plants is hydrogen. but that's not enough . you have to make sure that that hydrogen is actually being produced through an electrolyzer that's operating on 100 percent green. ah, renewable energy. sir, time for hydrogen right?

well, unfortunately, over the couch, you need a lot of hydrogen. like ready loads. boom, make mold steel into you out of hydrogen would require about 6000000 tons of the gulf. just to satisfy the steel industries hydrogen needs. you need almost as many wind turbines that you have to date is not impossible, but it is a logistical nightmare. and one of the big challenges is where we build these hydrogen ah, production facilities. it needs to happen in places that have that renewable energy capacity. the problem so far is lots of still making regions, dirt palette capacity. poke at least don't have plans to build atop any time soon. and piping more shipping green hydrogen from elsewhere requires infrastructure to do so. and that all means hydrogen can't be the whole solution. but the, the powerful way to simplify the problem that sounds almost too good to be true.

recycling you might not expect it, but still is already one of the most recycled materials in the world. more than a quarter of the steel may to day comes from recycled scrap steel that nobody needs . that's basically because the 1st step of purifying iron or is expensive melting. not all steel. well, that's much cheaper. but there are limits. each time you price a steel little impurities like copper and nichol can sneak in and we can the metal . that means you caught recycler forever. a 3rd solution is keep the block fences we're already using, but catch the emissions before they escape into the atmosphere. that's what advocates of carbon capture cooling for fossil fuel company said the principal, as simple. stick a box on top of the polluting pipe and suck up the c or 2 that comes out so you can use it and industry. oh stuart, safely under ground. the reality is trickier. today, capture rates are often low and casa hot. what's more of the fossil fuel industry

has used the promise of carbon capture and storage will cease? yes. as an excuse to keep on polluting. but when it comes to the company, that heavy industries, and let's do broadly agree that ccf the vital role to play alongside hydrogen, we're way behind and where will the promotional and going. and this is largely down to complete an auction on the of a policy level. this is eva penner from the cleaner task force. it's one of the few environmental organizations calling to put money into capturing carbon. one of the reasons why we, you know, we don't know answers to questions like capture rates or how would it work on a commercial scale is because your companies have had to actually reduce their mission. the international energy agency expects carbon capture to cover half of will steal production by 2050 in the climate friendly scenario. if it works, it would free up hydrogen to be used in other processes that are also hot clean. but today, we don't really know what share of emissions ccf can actually capture from steel.

if steel make a stick to blast furnaces, but c c s doesn't quickly become cheap or efficient. the cold a burn will just keep on polluting. we console steel by giving up on it, but there's a huge amount policy makes and companies can do to get the tech solutions working with age comes this them, we've all heard it. but what of the elderly and your community started welding houses with eggs, then? nuts and jagged me? well, i will not be able to sleep. oh, wink in that house even if i was forced to. i'm pretty sure a roof made of egg will certainly fall on my head. but probably that is why the elderly in a village in south india are wiser than i am. he has white arriving in gun up at the berlin. it appears to be a village like any other in india's, coming not to state the young have all left only the elderly,

demean custodians of local knowledge, including the visa vit villagers once been to their homes. you are happy i were made, but i used to watch my father make them so your father, handcrafted them, used to killing to make them yes. construction engineers out of in the manhattan and pad. but as of the money m, want to tap into this ancient knowledge. they have visited more than 40 villages around them and not do in recent years. investigating the old techniques and building materials either community bollinger rather than in the used to be only one or 2 masons per regional, local people would work together on the la mill. and so anyone over if you knew the anti prose monday, how a mud mixture should be and how to choose to monitor what to add to the lime and it's consistency and about grouping and floating with them. but we interviewed that elderly people in each region and benefited from their knowledge on the way he's on

the landry of $17070.00 at all storm meas, in keen trojan is one of the last of his guy. and he's building a house 650 square meters anadia in villa coin in the old. he had a device to the line makes to lend the plaster fat and she's in the business for 50 years. he's delighted to share the secret of traditional construction with a new generation of windows. one of the houses in my village used to be a big bag that was on the in the city. i'm going to structure like this one, but we had my was a line and i little this is tom. i went off seemingly wondering what i have in the minority and had a balance of money and have been building with natural mathias for the last 3 years . thinks like my balance not or january i shall go use in construction for

centuries to bind line, glasgow or the reading of it. i'm going to go home shoes, local media, one local soil. luckily, sources for a lot only then easy to structure. it does not impact whitening the little body for me off putting a t d gone back there. i didn't read the maneuver and put a bunch of money to build her and always staying holiday home in the countryside. again, the natural foaming. i'll be wanted a lazy, couldn't, organic farming because we wanted to provide good food or whatever the case number one to 49. and since we wanted a house to stay in, when we came out here to be part of why not do the book or the 7 year old twins then by and sat begun love to play at their country home in paris to write the walls are quoted with 5 layers of lime plaster that allowed the house to breathe. this natural material keeps the house cool in summer and warm during

winter. the what for the for source from a reclaimed wood market. when he got a d. d and her husband hammer dodge among a growing number of income house owners who have opted for green building materials . i don't rent manhattan and, but at the balance of the money em have already completed numerous sustainable projects, mainly in rural areas including schools. depending on model and workmanship, building, cor surprised it around $3000.00 rubies, or $35.00 euros bar square meter. by contrast, a conventional house costs less than half that some wanted to have a deep de doesn't regret, investment. she believes it's already being dividends in a cleaner, more sustainable environment for her children. we all feel this rather breaks the incessant construction sounds and the dust we while been there. whether

it's our own house being built, our back new house around the corner, which is being reconstructed. but these, this material is literally the building block of the concrete jungle that we live in today. but after all of this, construction is done. it leaves behind tons of this wasted material, but like more things that we have talked about on the shore today. there is a company in southern germany which has found the solution to this as well. germany creeds, 280000000 tons of concrete waste every year. but at least this rubble soon be re purpose into new concrete face. accompany in southern germany, specializes and recycling building materials. a crushing machine turns the concrete pieces into small granules, which are sorted by size. the granules are then sold to cement, manufactures what's good for face can also be good for the

environment. china onsite processing can save millions of truck kilometers how the kilometer inch bomb sand used to pre is concrete, is usually done from large pets, then transported hundreds of kilometers. the same is true for gravel. the 2nd component in concrete, but sand and gravel are becoming scarce. at this construction recycling plant, old red roofing tiles are also used to produce concrete, recycled sand is taken from an old construction pit. it's cleaned and served before being sorted by size of the of a bomb. everything here used to be a bridge or a floor slab or a house and we're making something new from it was the problem of all this material would have ended up in landfills on, in some dump loganville. and now we can use it to make high quality building products that are used in new construction project. will i use the recycled

products? are then delivered to customers like this near by concrete manufacture. this company is different than most of its competitors. because globally, only 2 percent of building materials get recycled. but this company depends on recycled materials, which account for 30 percent of its entire production. and the recycled concrete is less expensive to le materials are mixed in this plant and then delivered to customers. the final product will look like this. a building material that many customers prefer over conventional products. other solutions are also being developed at this cement plant, for example, permeable, concrete that can absorb rain, water, helping improve urban climates. this is some of the big mazel this inch date. rainwater seeps through this concrete and goes under ground

one which can help improve ground water level. cinco vasa, household beautiful basal or done the enough her and then warm dry can cause to water to evaporate. muscle with eliminating hot surfaces is all mount him unkindness or heisen selection. i could talk this could help prevent concrete deserts, with completely sealed surfaces. recycled construction materials are also brought to this southern german company, which uses it to make concrete blocks. ingredients include recycled sand and recycled rock granules. they are constantly testing new stone formulas in the lab, experimenting with different colors, shapes and components to increase the portion of recycled content, which is 30 to 40 percent. the recycled look is intentional

and performing for you. we're primarily talking about up cycling horn quantity, we want to produce a very high quality design. b, this tile pattern creates an entirely new surfaces. you look on the, on the gum loyal what. this is, what it should look like. a new generation of recycled sidewalk with lots of green grass sprouting up in between and space for water to seep into the ground. this is what many customers now want. it's a new growth market for the concrete industry. i hope you found this episode interesting and filled with some solid concrete fact. colgate, no jokes. but do let me know what did you like the most about the shop? and what would you like to see more of write to us at ego india, at the rate of d, w dot com? we will keep bringing more stories to you about the impacts on our environment. and i hope you continue being a part of this journey with me. thank you so much. i will see you next week until

then have a lovely week number scott, thing with
