the mediterranean, ah, it's waters connect people of many cultures seen of almost rock enter far dockery drift along with exploring modern lifestyles and mediterranean where has history left its traces reading regal, hearing their dreams, ready to me this week on d. w. ah, with our cities are growing, but as new buildings rising to the skype, so to no 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 today, so hello, welcome to eco, india. i'm some of that are good. 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 of 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 waste. the ah, in furnace is such as this one includes rot, metal is melted at $1500.00 degrees celsius and coughed into radius shapes. material vital to this process is natural sand. yet after several uses the sand

dunes into foundry, dust agrees material that ends up in oakland. um o. laundry dust is actually oh, hazardous, medieval, which is a byproduct of industry on so many things going things matches have measured, which can be how well, especially for the, for going to be all the science as well as the walk up. because this is disposed of without i mean in all one space. and if it comes in, going backwards really walked out, especially rendered 3. and then what would happen is that we get into the site. this does the flag be off the site and on so contaminate the ground water? my nice what, how do you one second, i mean,

the good rap the city of fun and that seeking ways to address this huge race problem. walk down the bridge europe. in fact, we will find open dumping all the time and we've been all over this problem is increasing as the industry if foundry dustin collected and combined with plastic waste in a 7030 ratio, you get this a silica plastic block for money's quote, hardy themed up with up cycles decorah of the recycling company in on and to create the foss silica plastic blogs in 2018 each lake. our last a glock starts out as a dry mix of crushed plastic waves and foundry. does this mix did is put through an extruder and comes out the other side in the form of a study, ready to be moulded into any shape or size required within by mot. good add up

cycle. jekka takes pride in turning heaps of waste into something useful. hi my. my mother invites it. you can make something like this from plastic surprises that 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 each year using just a 3rd of the energy needed to make conventional bricks. what party have found ways to recycle waste into more places to what area do you ever think of this 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 calls and get people on the model x one. they would add this construction site in on and the silica plastic dials are being used to waterproof the walls, the heart of upside construction. i says the tiles work much better than cement what they call me. and i'm going to assume india brick gum. usually when you imagine pick him in the 4th thing you think of the water you for securing good is a part boring book is full of water on it. 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 products is using water than what, which is even less than what a family of 4 uses in the month. that is how much this 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 brakes on the same price. well,

that's good. how you can also reach this farm in the bible office. we're stuff will continue this. not picking it but anything to be off if it is collected. so it has not been this but them the top are going to start the collected book. the collected plastic waste is transported 35 kilometers of a on and 40 thing. their plastic is separated in preparation for processing with the foundry dust. while upside kentucky mostly produces bricks for construction. they create custom product to ah, add to form sauces to liquor, plastic glove, service flooring, furniture and even stationary. so you know, make is not based on the tv. so we end up on or dish and money. you could 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, by 2030. the un predict that 60 percent of the global population will live in cities amid the rapid pace of opening ation. sustainable architecture has become a buzzword. but what does it even mean? our reporter set off from berlin to find on to us. cities are growing, which means we keep on building but know what else rises with those glossy flat emissions. we all need space to live, but building buildings is terrible for the planet. the construction history counts from 40 percent of global c, o. 2 emissions that makes the pace of urban invasion. 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. dec keeps house in frankfort. the 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, lola. i'm su liana, and one year old mirror. they live in a pretty nice, pretty normal looking flight with a disco ball in the city center. but under this normal veneer, there's a robot lurking amongst them and visit well the energy center of the house, so to speak. every flight comes with this. i path that shows you how much energy the building is producing from its solar panels. and when it also shows how much energy are using and how that sucks up against her so called budget. and this were

warm water too. and there were a bit over budget because for kids to play fast. do you like taking bath? yeah. what would the weirdest thing about this whole thing is, is the ranking. so the all 74 units of the house are great and concerning their energy and warm 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 a bit to your gifts. this is sort of a competitive fuel. while it's actually sion, the dunc 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 a habit. at the end of the day were soon frankfurt, where the average salaries almost 60000 years a year. living green is an expensive privilege here. and,

and just because the building a screen doesn't mean all it's residents are all the people in here. i mean there's that the mosquitoes g class parking in the parking lot downstairs. most people here with normal frankfurt life, i don't know any fridays for future exist, 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's showing us how this whole thing works. that's the boy does. the building was designed as a passive house. that means it's air tight and the energy it uses its generative. but i didn't know was that it also comes from sewage to disney stuff. there are massive sewage canals in every city, and that dirty water flows into a treatment plan which has temperatures between $16.18 degrees celsius. these plates remove energy from the waste water. up of that energy has been sent to

a heat pump, which is this massive device here. this generates heat for the whole building of the input using the boys to get their teach. that house may be a success story, but it's built with all new materials, including lots of concrete. this is a circular house in berlin. it's a co working and residential space that takes a totally different approach to green architecture and professional speak. this is called a circular economy concept. so what does that mean? when we say we circular? there are 2 main aspects. this is simon lee. he's the head of the circular house project. one is nick from waste, from secondary resources, basically. and flip the boot in a way that after the life cycle of bidding, you can actually remove everything and we use it or throw it on the composed. for starters, the structure itself used to be the loading hall of an

o brewery. everything has embedded value, and this is dr. near marquee shawnee, a professor at the national university of singapore, and an expert who said that concrete to build that took a lot of conflict. and so you begin by recognizing the building itself as a kind of, as an asset. we got to pick up the construction side of the residential for which we'll have a flat that sure, a large common area and kitchen. so here you see we big 100 for and with what, nothing is, nothing exclude its own food. so you can remove like legal crude, 100 percent organic. so this is just play and behind the clay it's sprawl. and you have just put in a lot of lin strong and water invested. they also used woodward for insulation compress the strong up cycle plywood concrete and natural alternative to concrete me to hampshire in 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 life thick and was actually assembled of coffins we disassembled them and just like bo, this meeting moves out of that are all very cool, but how many of us have access to the people running? you go searching a 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. ringback putting a piece of something from the old building into the new building. so is it always better to re purpose and structure than to build a new one? if you look at it from the you to perspective and why i think they're more of that

company. because it's it is 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 to re purpose 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 le map. she is the head of the german green building council, and she spent most of her time reminding developers that's a cultural climate context where buildings are happening. and that building has to react locally to, to the surroundings. but good architecture is also about access. if greener buildings are just there for the 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 women 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 is actually the wrong strategy and the strategy is to so many years. and now we have to deal with all the cars. by 2025, 2 thirds of the world's mega cities will be in asia where the pace of urban ization and need for housing is and comparable to that of germany. after 3040 years being torn down and being replayed, quality was not good or modern and anymore the, whether it's europe or asia building better will be a challenge everywhere because capital will always be inpatient. as architect romero tra said, investors want fast returns, but a building has many other stakeholders. we have very different definitions of what a good building is. how do you negotiate and mindsets, how do you align people towards a common goal? i think this is one of the biggest challenges that we face in industry today. the

real solution might involve a total re conception of what we think architecture is and promote indonesia now and a community in central. so let me see province. that was devastated by a series of natural disasters in 2018. faced with the mammoth task of rebuilding, it rediscovered a traditional material which it turns out can withstand natural hazards far better than most conventionally building substances. 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 earthquakes, including one with a magnitude of $7.00 bull on papa was one of the many villages affected and calmly . district, an area that's popular with tourists from polymers, 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 the table. and then at a glance, this looks like a logo, a structure used as a traditional meeting in place and 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 assume these new bamboo houses are like them or yet little open house either. in fact, these houses are the same shape as older co valley houses. but the metal kind of, i mean my main motivation was the need for shelter. we were informed that besides getting a house, we would also learn skills. we let them be life. 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 massive 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 romeus has worked with marwan and his friends for several months and we see that when you do there are also a 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 out of the it. that means and addition to rebuilding homes for disaster survivors,

we can also provide economic benefits for those who have joined the training program and that he 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, including 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 the con, grant, as seen as an indication of poverty, latin buckle button it. gus, i know 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 his 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. and i wonder what it would be like to live in

a hobbit whole then state you. because our next report explores the work of swiss architect me to wish whose organic look homes are the epitome of climate friendly design. ready at 1st glance, this earth house in switzerland and bennett nature looks more like a hobbit hole than a conventional home. but its aesthetic exterior conceals one of the most environmentally and climate friendly homes available. there, the brainchild of swiss architect peter fetch who invented these earth houses over 40 years ago. this is sound. it's just a logical solution in terms of environmental protection, integration and ecology. hill. they're colorful. normally houses take space away from nature. here vegetation can grow on the earth covered roof and the house smelled harmoniously into the landscape. they used to much been

so easy as a 50 centimeter layer of earth, but the cover increases in depth. further up on the top, there's a 120 centimeters of earth, so a lot can grow. there isn't much ceiling, we're restoring green space. being in the beginning of 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. rich does she coat? 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 pater fetches, designed from the 1st time he saw it. they didn't b. o, mad you don't notice your under earth, you've got these big windows and you see greenery everywhere you look. oh, i'm comfortable living here and the indoor climate is very steady. it indeed is esteem at us, glided clean moth. 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. decamp near zurich. generally, he's wary of the trend to integrate ever more high tech elements in architecture.

is the savvy that i know there's a returns in nature to simplicity and why all these expectations people are born from the womb after all thrift. i had just felt like no clue. why do we keep building everything, square it, dive into the room bowing. 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, this is 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. i've had to build houses a bit like a kid to playing in a sandbox, increasing the height here, or 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 fix them, blah. he know the couldn't see. i was had, oh still can lease earth houses are ahead of their time. but more and more people are taking interest in alternative living concepts, blue litter size. obviously, 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. we k, hulu, will our understanding of architecture change? how can we live more sustainably pay to fetch his design, may provide at least partial answers to these questions. could you imagine living in an earth who like the one you just saw that on a lot of realities to consider before taking that lead? and that's why we have eco, india. we continue to give you perspective about the why in the house of going

green city wound and we'll be back next week from an entirety. good bye. and thanks for watching. ah ah, ah ah, ah, with

who a is the end of the pandemic in sight. we show what it could look like. return to normal. and we visit those who are finding it difficult.

with success in our weekly coven 19 special. every thursday on d. w. 2016. as like a bunch of the queen customer wants to see if germany was for me the last few years, have been quite a ride. get it early in touch with it on the homework when it comes to jem a bid on. of course, always look right in the algebra kids, but perhaps the biggest on the new hobby applies. i'm no longer approved. i want to be in the news report americans. but when you're feeling altogether, you'll realize that culture, the not the way of living, are you ready to meet the driver and then join me, right? just do it on b, w. ah ah a

ah all we can be the generation that ends it for good malaria must die. i'm millions can live ah

ah ah ah ah, this is dw, live from berlin, ukrainian forces achieve their biggest breakthrough in the south of the country since the war began. that been pushing forward with our friends in the strategic southern regional kept song one of 4 regions illegally annexed by moscow last week .
