material away. ready product from metal production, which is usually dumped into nature, mixed in a bit of plastic waste and it's done eco, ah, next on d w. as you go to it is a thought they were great you ah, with our cities are growing, but as new buildings rising to the skype. so the emissions pollution and waste

because construction is one of the least sustainable industries on the platform. and yet it a lot for, for ways to build better. we have several coming up on to the issue. hello, welcome to eco india. i'm some of that i now concrete is literally the foundation of modern life. the most used material in a built environment. but the list of its negative effects is long, including a colossal carbon footprint and waste that chalks landfills. a company here in india has come up with an alternative building block that makes use of not just one, but 2 types of problematic whist ah, in furnace as such as this one includes rat. metal is melted at 1500 degrees celsius and cast into radius shapes. m a detail vital to this process is natural

sand. yet after several uses the sand dunes into foundry dust, material that ends up in opened um o. laundry dust is actually oh, hazardous, medieval, which is a byproduct of the industry. it on so many things contains messages, heavy measures, which can be hard, especially for the flood realty, all the sign as well as the water, because this is disposed off without i mean, in or one space. and if it comes in, going backwards really walked up, especially rendered 3. and then what would happen is that we get into the site. this does the flexibility of the site and on so contaminate the ground water money . what,

how do you want to come mean the good rap the city often and that seeking ways to address this huge waste problem, walk down the bridge and europe. in fact, we will find open dumping on time and we've been all over this problem with leaving as the industrial brain. if foundry dust is collected and combined with plastic, least in a 7030 ratio, you get this a silica plastic luck. for money's quote, hardy teamed up with up cycles, decorah of the recycling company in on and to create the foss silica plastic blocks in 2018. each lit up last big block starts out as a dry mix of crushed plastic waste and foundry. does this mix, did it put through an extruder and comes out the other side in the form of a study ready to be molded into any shape or size required with inside mot work

could add up cycle. jekka takes pride in turning heaps of waste into something useful. hi my. my mother invites say you can make something like this from plastic one surprises them. well, i didn't understand in my village, nobody imagined we can make something like this from this race. surprises them all, 11 and i like this open. one is again, this could be a scalable new use for the 3000000 tons of foundry dust. india produces e t using just a 3rd of the energy needed to make conventional bricks. what party have found ways to recycle waste into more places to whatever you have to think of with the problem when you have everything of a problem. so the waste is also relevant. this isn't done. so we have no food, then we can work it up. it's a lot more than it can be picket on when people are you can take it to one poll,

them trying to get your phone call them could be put on the model x one. they would add this construction site, the 9 and the silica plastic dials are being used to waterproof the walls, me hot grove, all of upside construct says the tiles work much better than cement what they call me. and i'm going to go swim. india brick gum, usually when you imagine pick him in the 4th thing you pink off in the water, you for securing good isn't. that's a part boring book is full of water on it or do there's a part of the process. now what if i told you that instead of the technology that is being used to make all the corridors is using water water, which is even less than water family of 4 uses in the month. that is how much the only amount of water that goes into it. lea, a lot of the water that goes in doing the silica plastic blogs are also 2 and a half times stronger than regular breaks of the same price for the good. how you

can also reach this farm in the bible office. we're stuff will continue this not picking. it brings it to be off if it is collected, it is not in this bottom the top of what it is collected. the collected plastic waste is transported 35 kilometers of a on and 40 thank link their plastic separated in preparation for processing with the foundry dust. while upside kentucky ramos the produces bricks for construction, they create custom product to ah, add the form sauces to liquor, plastic glove, service flooring, furniture and even stationary. so no may not be over to you so we can or dish and money squat heidi's innovative process of mixing foundry dust with plastic is setting an

example for the recycling in the metals and engineering industries. such circular approaches to industrial byproduct, open up new economic opportunities while helping to preserve the environment. ah, my 2030. the, you want predict that 60 percent of the global population will live in cities. amid the rapid pace of opening vision, sustainable architecture has become a buzzword. but what does it even mean? i report a set off for berlin to find on to us. cities are growing, which means we keep on building, but no one else rises with those glossy flat emissions. we all need space to live, but building buildings is terrible for the planet. the construction history accounts for almost 40 percent of global c o. 2 emissions that makes the pace of urban i vision pretty alarming. when we heard that one of the world's biggest

energy plus apartment buildings was in germany. well, what did you think we did? we've come to the most energy efficient of them. all that keeps house in frankfort . this building actually generates more energy than it consumes, hence, energy plus and like proper reporters, we just barged into someone's house. this is david and his daughter, lo. i'm a few liana, and one year old marrow. they live in a pretty nice, pretty normal looking slot, with a disco ball in the city center. but under this normal veneer, there's a robot lurking amongst them and visit the well, the energy center of the house. so to speak, every flat comes with this, i ipad that shows you how much energy the building is producing from its solar panels. and when it also shows how much energy are you and how that sucks up against her. so called budget. this were warm water too, and there were

a bit over budget because the kids take baths. do you like taking bath? yeah. what was the weirdest thing about this whole thing is, is the ranking over all 74 units of the house are rated and concerning their energy and we're water using the picture. you can see what are your neighbors. yeah, i think you can't ha, which is good. i think, you know, i think this whole thing is of it gives, this is sort of a competitive fuel. while it's actually shut down, humans, new competition for change to happen. anyway, the main question is, does the i pad work that we 1st moved into the apartment? i did check it every day or every week or so, and we were like, oh yes, were above the average or something. and now it gives you a kind of motivation to, to change your habit. at the end of the day were soon frankfurt, where the average salaries almost 60000 years a year. living green is inexpensive privilege here and,

and just because the building has green doesn't mean all it's residents are normal . people live here. i mean, there is head the mercy, just g class parking in the parking leg downstairs. most people here with normal frankfurt life, i don't know any fridays for future. i to this living here or something like that. we had to cut our visit short because guess what? we got to meet the person behind the i pad. frank anchor is the chairman of frankfort city housing management. and he was in the basement. just kidding, he showing us how this whole thing works. just avoidance of the building was designed as a passive house. that means it's air tight, and the energy it uses is regenerative. but i didn't know was that it also comes from sewage division of either stuff. there are massive sewage canals in every city, and that dirty water flows into a treatment plan which has temperatures between $16800.00 degrees celsius. these

plates remove energy from the wastewater that energy has been sent to a heat pump, which is this massive device here. this generates heat for the whole building. i thought it was using the boys to get there to start. house may be a success story, but it's built with all new materials, including lots of concrete, a circular house in berlin. it's a co working and residential space that takes a totally different approach to green architecture in professional speak. this is called a circular economy concept. so what does that mean? when we say we the circular, that 2 main aspects. this is simon lee. he's the head of the circular house project . one is the, from waste, from secondary resources, basically. and in a way that after the life cycle of bidding, you can actually remove everything and we use it or throw it on the compost. for

starters, the structure itself used to be the loading haul of an o brewery. everything has embedded value with this. this is dr. near marquee shawnee, a professor at the national university of singapore, and an expert who was involved in that concrete to build that took a lot of conflict. and so you begin by recognizing the building itself as the kind of as an asset. we got a peak of the construction side of the residential for which we'll have 8 flaps sure. a large common area and kitchen. so here we big 100 percent with what? nothing is. ne, nothing exclude. it's all screwed. so you can remove like legal conclude 100 percent organic. so this is just play and behind the clay, it's just for all you have just put in a lot of lin strong and water invested. they also used woodward for installation compress the straw up cycle plywood. help create a natural alternative to concrete of hampshire line and recycle plastic bottle

doors. dancers nicole working area simon and his colleague sasha, showed me perhaps the world's most unknowingly famous meeting booth. rescued actually material from a yoko ono exhibition in light thick. it was actually assembled of coffins we disassembled them and just like built these meetings out of that are all very cool, but how many of us have access to the people running, you know, show sourcing cycled materials is not only hard. we simply don't have enough people doing it, take it from an architect, you need a whole industry to support that. it has to be done at scale. it's about building an ecosystem around this idea. i don't think it's just simple gesture of putting a piece of something from the old building into the new building. so is it always better to repurpose mental structure than to build a new one? if you look at it from you to perspective and why is either more of that happening,

because it's just more difficult, you need to put in the extra work to basically analyze the building. what can i do with it? what kind of resources structural system have enabled to repurpose for many they feel if we just knew we have everything under control and we don't have all these unknowns and we don't have any on calculated risk. this is dr. christine the map. she is the head of the german green building council, and she spent most of her time reminding developers about the death and cultural and climate context where the buildings are happening. and that building has to react locally to, to the surroundings. but good architectures also about access. if greener buildings are just there for one person, then it fails as a social project. 40 percent of the living space and circular house would be devoted to social housing, and most of its residents will be clear when of color. but these are just some of

germany's approaches to making architecture, greener. it focuses energy conservation through technology, which of course, isn't a solution for everyone. once it's all in the building industry, it's actually the wrong strategy and the strategy that followed through so many years. and now we have to deal with all the consequences by 2025, 2 thirds of the world's mega cities will be in asia, where the pace of urban is ation and need for housing is and comparable to that of germany. after 3040 years have being torn down and being replayed, quality was not modern and anymore the whether 0 or asia building better will be a challenge everywhere. because capital will always be impatient. as architect romero tra said, investors want faster returns, but a building has many other stakeholders. we have very different definitions of what a good building is. how do you negotiate this mindset? how do you align people to? it's a common goal. i think this is one of the biggest challenges that we face in industry

. the real solution might involve a total reconstruction of what we think architecture is to indonesia now. and the community in central philosophy proven that was devastated by a period of natural disaster in 2018 face to the mammals task of rebuilding it. we discovered a traditional material which had thumbs out can withstand, naturally have far better than most conventional building substances. ah, central civil way c is no stranger to natural disaster in 2018, the province was hit by a tsunami lance lines and a series of hers quakes, including one with a magnitude of 7.4. bull on papa was one of the many villages affected in we district, an area that's popular with tourists from paolo city,

together with the organization architecture. so frontier indonesia, a group of young men are now rebuilding flattened homes from scratch with bamboo. it's also hope the project will provide economic stimulus that's affiliated with that. the little man at a glance, this looks like a logo, a structure used as a traditional meeting place. it's been it, but the detail shows similarities to original cloud houses. yeah. called gum period buller noah b. there are slight differences. most people today are only familiar with lobos, and as soon these new bamboo houses are like them yet little open house even in fact, these houses are the same shape as older co valley houses. but some of the kind of my main motivation was the need for shelter. we were informed that besides getting a house, we would also learn skills. we would get that i'm feelin, they were shown the design and then were taught the whole process to turn the idea into reality. from harvesting the bamboo to finishing the construction long ago,

kalauia used to have a tradition of wood and bamboo architecture with modernization. people began to build their homes with brick and concrete. brick houses were prestigious, but the mass of earthquake caused these houses to crumble, and many people were crushed under the heavy structures. now residents are looking for safer alternatives. bamboo is grown widely in indonesia. it's lightweight and flexible and is more earthquake resistant rabbani romance has worked with marwan and his friends for several months and we see that when that gets you there are also go logical benefits to using bamboo such as low carbon emissions and water conservation. because bamboo plans can restore groundwater in dry areas, bamboo will also be able to restore damaged ecosystems in the region. most importantly, bamboo is very interesting to him because it requires skilled manpower at the at that means. in addition to rebuilding homes for disaster survivors,

we can also provide economic benefits for those who have joined the training program and that has some bamboo houses do still, however, have an image problem. according to rama solid, he's the director of the central solar ways a carsa institute, which is implementing the bamboo housing project in partnership with architecture. so frontier indonesia, the alarm system found out that kamisky nandita on poverty, conducted by social and statistics agencies include certain indicators, gone into got one of them is the material that people use for their housing. ah, not the real em dual duncan on the use of anything other than kong, grant, as seen as an indication of poverty. latin buckroe button at the governor must such categories affect the way we see things done go more than mumbo nodded perception. myself. housing built with concrete, became an aspirational goal for many upwardly mobile families. even though it was not a construction material that was well suited to conditions here in the region. the

carsa institute has now developed various building designs that use bamboo for private use and for public buildings like local schools and the policy on to health center. my one plans to move into lou bamboo house with his family soon and he's proud of what he has learned along the way. i say to the study this chair that i'm sitting on now as a result of this training process. before this, i found making your chair like this really difficult. it's a side benefit of the few months of training. before he built this house, my one earned his living, doing on john's. but with his new set of skills, he hopes to make a new career for himself. just like marwan many residents here now have safe homes, as well as the means to make

a secure living in the future. ever wonder what it would be like to live in a hobbit hole. then stay too because unmixed report explores the walk of swiss architect me to wish whose organic look homes are the epitome of climate friendly desires. ready at 1st glance, this earth house in switzerland invented nature looks more like a hobbit whole than a conventional home. but its esthetic exterior conceals one of the most environmentally and climate friendly homes available. there, the brainchild of swiss architect, feita fetch who invented these earth houses over 40 years ago. this is down. this is just a logical solution in terms of environmental protection, integration and ecology hill. their color, we normally houses take space away from nature here. vegetation can grow on the earth, covered roof,

and house smelled harmoniously into the landscape. is too much been so here there is a 50 centimeter layer of earth, but the cover increases in depth. further up on the top, there's a $120.00 centimeters of earth. so a lot can grow, there isn't much ceiling, we are restoring green space. being the, the green. placing earth houses are low energy, foster biodiversity, and are cheaper to bill than conventional houses. first, a woven steel grid is erected. this is then filled with concrete. and then covered with a layer of polyurethane or clay. but what about the inside of the house? our host was already expecting us. we reached osha co. the house has curved walls, high rounded ceilings and fanciful paintwork. the rooms fused together elegantly

habit only she has been living in this earth house for 31 years. he was fascinated by pate of fetches, designed from the 1st time he saw it, then to threaten and b. o. mad you don't notice you're on the earth. you've got these big windows and you see greenery everywhere you look all i'm comfortable living here and the indoor climate is very steady it in. is he steve middle school? i think cream off these stone carved houses in tunisia or these and cap and osha turkey serve as inspiration for peter fetch. he built his 1st earth house, 1974 for his own family. today there are about a 100 and switzerland, austria, germany, and on the crimean peninsula. he also designed an earth house style public park in the small town of d dakota near zurich. generally, he's wary of the trend to integrate ever more high tech elements in architecture.

is the savvy, the, and there's a returns in nature to simplicity and why all these expectations people are born from the womb after all, you have to have just felt like you clicked. why do we keep building everything? square shaped eyes. yeah. what about if he had a key? ah, he's been retired for a long time, but that's not slowing him down. even at age 79. he's always working on new projects. he's currently designing an environmentally friendly apartment building robin booth about this building method involves very few materials. i don't need to be all let precisely i'm not fitting boards down to the centimeter. so i can follow my intuition a lot more effort to build houses a bit like a kid playing in a sandbox, increasing the height here all there. it's creative. if i could use 3 d printing, that would be the best total. then i could make the design here in switzerland,

send it to china, and they'd print the houses and we fixed and blah, he know the couldn't as he always had out through these earth houses are ahead of their time. but more and more people are taking interest in alternative living concepts lit society. obviously, lately i've been getting more and more requests. people are paying greater attention to the environment and they're realizing building a freestanding box isn't environmentally friendly. again, with will our understanding of architecture change? how can we live more sustainably? peter, such as design may provide at least partial answers to these questions. could you imagine living in a cool, like the one you just saw that on a lot of realities to consider before taking that lease? and that's why we're the going deal. we continue to give you perspective about the

why in the house of going green, 51, and we'll be back next week from our entire team. good bye. and thanks for watching . mm. ah ah ah ah ah, ah, with

who o one, continent. 700000000 people with their own personal stories. europe, with everyday life,

with what europeans fear and what they hope for focus on europe in 30 minutes on d. w. and to the conflicts own no sooner had president putin, amex, for regions in ukraine, than these troops were forced to flee from a key city. and one of them for humiliation wasn't lost on russian commanders. i guess this week from care of a horse off craft deputy head of the presidential administration. as you craig back to the food and into a corner where he might use his nuclear arsenal. conflict zone it 90 minutes on d o. w. oh, they are determined dynamite and the pillar of sticks and society,

a symbol of arbitrary rule. in the struggle for justice. taxes the right to levy taxes and the obligation to pay them both inherent in the sovereignty of the nation states and their citizens. but what happens when the power of taxation is undermined a tax on top of the tax on top of the tax that was due. well that broke the camel's back. i've been rambling forever, thinking to myself, when is it all going to come crashing down? hey, will pay taxation and politics starts october 21st on d w ah

ah. this is d. w. live from burly shooting and thailand leaves more than 30 dead, including more than 20 children. as a man opens 5 in a day care center. also on the program, russian rockets, lima, to homes in the ukranian city of separation.
