10:30 am
ah, who did you do before? ah, i painted a she survived schmidt's thanks to music and me. he was the nazis favorite conductor to visions under this wants to go a documentary about the sounds of power and inspiring story about survival. music in nazi germany. watch now on youtube dw documentary, the oh, hello, i'm sorry because the body and sorry, need to remove this mask. not a huge fan of it anyway. keep, keep winning my make up. but what option do we have? look at all of this construction dusted on my health. anyway, i'm sorry,
10:31 am
got the body and you're watching ego india. and today i will take you along with me to explore innovations that are offering improvements to 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 or g once every month. and maybe also live 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 deli ice and people who live near the capitol region would share my sentiment. let me show you this case is a beautiful city located in the foothills of molly. as in india mountain sate also dot com, the beautiful 15 ganges flows through here under the popular we can get away for more delegates. i mean, i've given a choice. no one would deny living here. i mean, also because ali is a city of extremes,
10:32 am
the heat wave del coil 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 time to 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 husbands. patterns will move here to skip the toxic air pollution that plagues delhi and it's greater metropolitan region known as the and c r. basically the idea is off for making my aim loss feel more comfortable with respect to all the unfortunate illnesses that you encountered in
10:33 am
places like n, sciatic cetera, so in our diabetes and pressure, et cetera. so wanted to bring them to a place which was more peaceful and more connected with the house is not just located in a beach would sit. it is also building materials that are easier on the and one and then conventional homes above all, with an alternative brick build by its makers as goblin negative. that is because it addresses one source of the stifling, the small dick 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 brick, he named a girl creed combines groped wrist like paddy straw with the mineral binding since 2020 his company green gems has produced thousands of blocks that it says have
10:34 am
helped capture more than 130 tons of climate heating, carbon dioxide. so in the crop is growing, it absorbing c o 2 from the atmosphere and it has basically embodying it. but if you leave it or become for the burn, the theater goes back of the atmosphere. essentially 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. so now we're just chemically bonded within that concrete. and that is how we're actually able to run the carbon cycle and put that theo, to ring to this mix. and because it has chemically bonded, it does not ever go back. i'll get the atmosphere. the bricks are lightweight and easy to handle. they're also robust. and offer a better permanent 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 expects to be of continued construction. boom, clean sort of needs to be fired under both 1000 degrees in degrees to create good
10:35 am
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, going to be 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 call. so you can imagine how much of emissions i've taking place because i grew greed doesn't just have the potential to go pollution caused by double burning, and clay killed the bricks and the factored by franchise partners who sold harvest residue from local font that generates extra income for farmers and got emissions from transportation and logistics till we broke helicopter to do they come monday to lose their common multiple formats. depending on how it is harvested, we pile them up here. and you can see this dining hillock of fall by the store here . and after that happens, the once we receive it here,
10:36 am
the next thing that we do is we using a threshold machine. it's regular farm equipment that has been used in centuries. so reuse that and we resize them the job, them up into smaller but because once job and so the stubble is combined with a pit tended binder also made from agricultural residue. i'm not dr. byproduct of the steel manufacturing. this is up mixed up into the go, the crop residues and the flash and the most important competent without which aggravate cannot be made, which is by. so those are the bags of mine, though we manufactured it and reside in our own manufacturing unit. half an hour after mixing, the egg creek is molded and left to sun dry for a week, prized between $26.55 rupees each. less than 60 years since a single block equals the size of $8.00 to $10.00 red clay bricks. that makes it
10:37 am
a cheaper option. that was multiple problems. one, your waste gets reduced ah, to stubble burning as you said, gets reduced 3rd, but hops. 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 us, which is a good thing and for it, but has also the fact that it can trap guideline and put it into our buildings, which gives me a way to sequester mike oven, and i believe this is a wonderful idea that can we move forward with back and russia gauge, civil arm is busy at locksmiths. he was swamis construction site. it is the 2nd house he has built using agra creek. thank you said the model that come all an income below it is very easy to work with. first of all, one block is bigger. been,
10:38 am
are single conventional, pretty much so it gets faster to work with. i do not have to use a lot of more study that a 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. this saves me time to learn more about going, how technology and nature can come together and how we can be responsible or not on this. so i took the responsibility with the break 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 of a home close to nature built with the bridge that can be produced almost anywhere laying the foundation for, built and bundle. and that's designed to protect our natural resources. ah,
10:39 am
feel if killing me in my mind. yeah. the same measure that you are you dancing? got home and even the back of this watch is middle si, stainless steel. 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 meter in the feel, your carbon footprint goes up. damn this one. but there are some things that can be done to deal with the ad was in the back door feel on the environment. this is the metal that makes the modern world tip. imagine a life without it. no cause homes, gadgets, 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 wealth, greenhouse gas pollution. and bizarrely,
10:40 am
we're actually going to need a lot more of it to clean up our economies. so how can we make steel green and what's wrong with the industries favorite solutions? there are 2 reasons. the steel making process was so dirty. the 1st at purifying the iron or needed the steel by heating i annoy choco fires o mixing it with cooking cole. in big blast furnaces, you can extract pure iron from rock. not because 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 lot of c o 2. the 2nd reason steel sucks of that it takes colossal amounts of energy to power this process, and most of that comes from you guessed it, burning cold. so what should still make us be doing right now? either gen hydrogen, hydrogen, only. jim's a wonders all hodgen hydrogen is
10:41 am
a gas and fuel that can be made cleanly with renewable energy. oh, much less cleanly with fossil gas. if you reduce ion all 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 20, the beauty about this concept is yes, you 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 timing of the 2nd step and then feeding the purified ion into an electrical photos. these devices meltdown. scrapped steel or reduced ion with high currents of electricity that turn them into liquid state. and ideally that 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 deliver the wealth 1st batch of fossil free steel to comic of over
10:42 am
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 lives. kind of feels like an onion. this is caitlin'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. i'm renewable energy sir. time for hydrogen. right? well, unfortunately there was a catch. you need a lot of hydrogen,
10:43 am
like really loads make mold steel into you out of hydrogen would require about 6000000 tons of the golf. just to satisfy the steel industry, hydrogen needs. you need almost as many wind turbines that you have to date is not impossible, but it is a logistical nightmare. 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 steel making regions, dirt, habit capacity, or at least don't have plans to build a top anytime soon. and piping or shipping green hydrogen from elsewhere requires infrastructure to do so. and that all mean hydrogen can't be the whole solution. but the powerful waste simply by the problem that sounds almost too good to be true . recycling you might not expect it,
10:44 am
but still is already one of the main recycled materials in the world. more than a quarter of the steel made today comes from recycled scrap steel that nobody needs that basically because the 1st step of purifying iron or is expensive, nothing non wholesale. well, that's much cheaper. but there are limits each time you price a steel little impurities, like cauffron nickel can sneak in and we can the metal. that means you can't recycle it forever at that solution has to keep a blast furnace as 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 companies say the principal, a simple stick box on top of the polluting pipe and sack up the c or 2 that comes out so you can use it in industry or start safely underground. the reality is trickier. today, capture rates are often low and costs are high. what's more, the fossil fuel industry has used the promise of carbon capture and storage or ccf
10:45 am
as an excuse to keep on polluting. but when it comes to be caught by the heavy industries, analysts do broadly agree that ccf the vital role to play alongside hydrogen. we're way behind them where they're going. and this is largely down into the inaction on the policy level. this is eva penner from the clean at hospitals. 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 the answers to questions like capture rates wouldn't work in a commercial. is because your companies haven't had to actually reduce their emissions. the international energy agency expect carbon capture to cover half of all steel production by 2050 in the climate friendly scenario. if it works, they would free up hydrogen to be used in other processes that are also hard cleaned. but today, we don't really know what have a mission cps can actually capture from steel. if steel make a stick to blast furnaces, but sees yes, does of quickly become cheap or efficient,
10:46 am
the cold, a bird will just keep on polluting. we cancelled 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 gone, visit him. we've all heard it. but what of the elderly in your community started willing houses with eggs and not said jagat. 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. we'll 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 way iving in going to put the plan. it appears to be a village like any other in india, from in 9 to state. the young have all left only the elderly, demean custodians of local knowledge, including the reason which religious once been to their homes. you are happy i will
10:47 am
meet, but i used to watch my father make them so your father, handcrafted them, used a killing to make them yes. oh, construction engineers out of in manhattan and product. 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, but regional board local people would work together on the la mail. and so any $1.00 oh $1.00. if you knew the anti pro slender, how a mud mixture should be and how to choose to model what to add to the lime and it's consistency and about grouping and floating with them. we interviewed elderly people in each region and benefited from their knowledge on the way he's on aladdin 3, opening $7070.00, or stone mason. cain at trojan is one of the last of his guy,
10:48 am
and he's building a house 650 square meters. the media in villa point in the old style advice to the line makes to lend the plaster effect 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. on the more particulars of all the houses in my village used to be a big bag. this was on the, in the city structure like this. but we had mud walls of a line plaster and tile room. this is tom. i went off, seemingly wondering what i have in my head and had a balance of money and have been building with natural materials for the last 3 years. things like my balance not are january i sugar use in construction for centuries to bind line glasgow. me, what reading of it,
10:49 am
i'm going to go home shoes, local media, local soil. luckily sources for a lot of only then is it a structure? does not impact whitening the little body from that army off? put it have a t t contacted the maneuver and put a bunch of money to build her and all started holiday home in the countryside. again, the natural foaming. i'll be leaving the organic farming because we wanted to provide good for, for our number 149. and since the wanted to house to stay in when we came out here, we target. why not do the book or the 7 year old twins then by and certainly gun love to play at their country home in bed on dry? the walls are quoted with 5 layers of line plaster that allowed the house to breathe. this natural material keeps the house cool in summer and warm during winter. the vote for the roof for saws from
10:50 am
a reclaimed wood market. pulido at 80 and her husband hemorrhage are among a growing number of middle income house owners who have opted for green building materials. i rented manhattan and barret valesa, romania 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 per square meter. by contrast, a conventional house costs less than half that sum. when it ever did, d doesn't regrettably invest wind. she believes it's already paying dividends in a cleaner, more sustainable environment for her children. we all seen this rather breaks the incessant construction sounds and the dust we while been there, whether it's our own house being built on that new house around the corner which is
10:51 am
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 are that we have talked about on the shore today. there is a company in southern germany, which has found a solution to this as well. germany creed, 280000000 tons of concrete waste every year. but at least this rub will 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. so be good for the environment which either onsite processing can save millions of
10:52 am
truck kilometers. how many kilometers i'm spawn? sand used to produce 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 called let them up. all this material would have ended up in landfills on in some dump. and now we can use it to make high quality building products that are used in new construction project will i use it? so the recycle products are then delivered to customers like this nearby concrete
10:53 am
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 the 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, as cuz some of the vague mazel this interstate rainwater seems through this concrete and goes under ground one which can help improve ground water level
10:54 am
synchron fossil household beautiful bristles or done donato, and then warns can cause to water to evaporate. muscle with eliminating hot surfaces is all mountains, unkindness. ohausen flatten, 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 perform a good thing. we're primarily talking about up cycling horn quantity. we want to
10:55 am
produce a very high quality design speed. this tile pattern creates an entirely new surfaces . you look on the, on the guns loyal 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 gross market for the concrete industry. i hope you found this episode interesting and filled with some solid, concrete fact. colgate noah jokes. but do let me know what did you like the most about to the shore, and what would you like to see more of right to us at eagle 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. no must gotten through
