in combat, even fighting directly at the front. focus on europe. in 60 minutes, pointing to all you just go to uses with lots they will grey you think? oh hello. i'm sorry. got the lady and sorry need to remove this mask. not a huge fan of it anyway. keep keeps winning my mic up. but what options do we have?

look at all of this construction. dusted on my house. anyway, i'm father got the lottery 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 gazed at least once every month and maybe also live there between october in december because of the pollution. and maybe also man john because of the big heat. i mean, i can practically live this, but i feel more deli 8th and people who live near the capital region. what share my sentiment. let me show you. this is a beautiful city located in the foothills of our himalayas in and out mountain theater or through the beautiful, pristine ganges floor through here. and it is a popular we can get over for more delegate. i mean have given a choice. no one would deny a living. yeah. i mean, also the goes deli, is

a city of extremes, 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 is stubborn. burning likely is for a couple of those months. but that is someone who has turned 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 museum, a swamis overseen construction on a hillside home for her family and husbands. patterns will move here to escape 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 antibiotics at russell in

or diabetes and pressure, et cetera. for wanted to bring them to a place which was more peaceful and more connected to them. 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 daughters because it addresses bonds so. so the stifling the smog jokes deli and other immune cities during the winter. when farmer's daughter there feels to clear them of grub residue and dine for their next sewing season. to tackle the problem. don't johnny set out to dance dublin to a source. the brig, he named a girl creed, combines groped wrist like betty stroll with the mineral binding since 2020 his company green gems has you houses of blocks that it sees have helped capture more

than 130 pounds of climate heating, carbon dioxide. so in the crop is growing, it is absorbing c o 2 from the atmosphere and it has basically embodying it. but if you leave it or be come for the burn, the theater goes back to the atmosphere. essentially the cobblins i could put in a nutshell, now we stop at that. we take the crop residues, we mix it with mineral binders. so now we're just chemically bonded within that concrete. and that is how we're actually able to go. but the cobblins cycle and put that c o 2 into this mix. and because it has chemically bonded, it does not ever go back out of 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 a continued construction boom. clean sort of needs to be fired under both 1000

degrees in degrees 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, going to be so in fact, india is the 2nd largest producer of ricks. 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 come 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. so we broke helicopter to do they come monday to lose their common multiple formats. depending on how it has 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, 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 this double is combined with a potential 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 competence 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 creed 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 breaks. that makes it 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 a 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 and you said the more did that come aaliyah it open below it is very easy to work with. first of all, one block is bigger than

a single conventional, pretty much so it gets faster to work with. i do not have to use a lot of more study that. how dare, let's see yet, i have used only one block. that's the same size that it had been a year since i would have to do this big times this week. 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 break and other things that we are going to use in this place so that it is going to be a 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 a bridge that can be produced almost anywhere. laying the foundation for a built and bundling that's designed to protect on natural resources. ah,

feel is killing me environment. yeah. the same measure that you are you dancing? oh. * 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 in the feel, your carbon footprint goes up. damn this one. but there are some things that can be done to reduce the ad was in the back of seal on the environment. this is the metal that makes the modern world tip. imagine a life without it. no cars are dutch electricity. but this one, the material that aligns are built around carries a 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,

we're actually going to need a lot more of it to clean up our economy as to 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 need of the steel by heating i annoy the charco fi as 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 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 cold. so what should still make us be doing right now? either gen hydrogen, hydrogen. it only genes wonders all hodgen. hydrogen is

a gas and fuel that can be made cleanly with renewable energy. oh, much less cleanly 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 20, the beauty about this concept is and yes, you need 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, ton of the 2nd step, but then feeding the purified ion into an electrical furnace. these devices meltdown scrap 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. first 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 there is a catch. you need a lot of hydrogen like ready loads making will to steal 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, if 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 steel making regions, dirt, habit capacity for at least don't have plans to build a top anytime soon. and piping more 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,

but still is already one of the most recycled materials in the world. more than a quarter of the steel may today come from recycled scrap steel the new need that's basically because the 1st step of purifying i nor is expensive. nothing. non allstate. 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 the 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, a box on top of the polluting pipe and suck up the c or 2 that comes out so you can use it in industry or start slightly underground. the reality is trickier. today, capture rates are often low and costs are high. what's more,

the fossil fuel industry has viewed the promise of carbon capture and storage or ccf 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 and where the department is going. and this is largely down into complete inaction on the policy level. this is a panel 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 the answers to questions like, capture rates wouldn't work in a commercial scale, is because, you know, companies have had to actually reduce their emissions. the international energy agency expects carbon capture to cover half of all steel 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 to date that we don't really know what chair of emissions cclc can actually capture from steel. if steel make

a stick to block fantasies but siesta other quickly become cheap or efficient. the cold a bond 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? not said jagat, he 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 life 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 religious once been to their homes. you are happy i will meet, 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 manhattan and put it. 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 for regional local people who worked together on the la mail. and so anyone over if you knew the entire process, 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. but we interviewed that elderly people in each region and benefit from their knowledge on the way he's on the landry of $177.00. he had all storm meas,

in keen trojan is one of the last of his kind. 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 mud was of a line. and i little this is tom. i went off seemingly wondering i have been minority and had a little bit of money and have been building with natural materials 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 does not impact whitening the little body for me off putting a t d gone back date. i didn't read the maneuver and put a little bit 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 get farmer because we wanted to provide good food, whatever the case. number 149. and since we wanted a house to stay in, when we came out here to be taught by not necessarily the book or the 7 year old twins, then by and sat to begun love to play at their country home in paris. right. 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

water for souls from a reclaimed wood market leader and her husband hampshire, among a growing number of income house owners who have opted for green building materials around manhattan and barret, bella, sabra, 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 deed and regret investment. she believes it's already paying 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 me hide 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 the solution to this as well. germany creeds, 280000000 tons of concrete waste every year. but at least of this, rob will soon be repurposed 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, bon 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 it? so the recycle products are then delivered to customers like this nearby 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 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

synchron fossil household beautiful bristles or done donato, and then warns can cause to water to evaporate muscle with eliminating hot surfaces . these are 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 per cent. the recycled look is intentional and perform a good thing. 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 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 growth 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 later 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 with

who ah, ah, there's is the story of many ukrainians before russia's invasion, marta and siri had trained as volunteers for emergencies. since the beginning of the war, they have been in combat. even fighting directly at the front

focus on europe. in 30 minutes on d, w. enter the conflicts own with sarah kelly, my guest this week on conflict sound was one of the most prominent members of russia's well connected power, elite, former kremlin advisor, and economist fair. gay gloria now is the professor of economics and provost that fee on scope. his work illuminates how authoritarian regimes like potent survive. how does he assess put his grip on power conflicts on 90 minutes on d w. oh. i wish i could have done more save you i just click away. find out best
