like the long 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 during this week on d. w. ah . are cities accruing but as new buildings rising to the sky, 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 to me, so hello, welcome to eco india. i'm son of that. a 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 talks 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. ah, in furniture such as this one includes rot, metal is melted at $1500.00 degrees celsius and cast into various shapes. amandito

vital to this process is natural sand. yet after several uses the sand dunes into foundry, dust, grease material that ends up in oakland. so foundry dust is actually o hazardous material, which is a byproduct of industry on so many things contains messages, heavy measures, which can be how, especially wonderful ability all the science as well as the water. because this is disposed off without banging in or one space. and if it comes and gone backwards really walked up, especially rendered 3. and then what will happen is that we get into the site. this does the flexibility of the site and on so contaminate the ground, more money. what. how do you want to come mean the good rap the city often and that

seeking ways to address this huge race problem, walk down the bridge in europe. in fact, we will find open dumping upside and waste and all of this problem is leaving as the industrial brain if foundry dust is collected and combined with plastic waste in 7030 ratio, you get this a silica plastic luck for money's quantity themed up with up cycles decorah of the recycling company in on and to create the foss silica plastic blogs in 2018 each lake up 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 slutty ready to be moulded into any shape or size required within by mot could

add up cycle. jaqakira takes pride in turning heaps of waived 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 or tardy. have found ways to recycle waste into more places to what area do you everything with the problem when you have everything of a problem. so the waste is also relevant. so we have no food, then we can get a good fight. the lab morning can be put on when people are you can

take it to one, told them trying to get your phone call them. could you 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 florida is using water water, 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 into 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 to our office. we have stuff continuous, not picking it, but if it is collected, it has not been this, but them the top are going to be collected book the collected plastic least is transported 35 kilometers of a do our non 40. thank ling. their plastic is separated in preparation for processing with the foundry dust. while upside contract 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 that's not is not on base. it is all my team, so we can or dish and money. you could how he's innovative process of mixing

foundry dust with plastic is setting an example for the recycling in the metals and engineering industries. set 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 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 a few liana, and one year old mirror. they live in a pretty nice, pretty normal looking flat, 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 flat 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 the kids take baths. do like 2 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 considering their energy and warm water using the picture, you can see what are your neighbors. yeah, i think you can ha, which is good. i think, you know, i think this whole thing is a bit if this is sort of a competitive fuel, while it's actually should be done, 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 is green doesn't mean all it's residents are all the people in here. i mean, there is that the mercy does g class parking in the parking leg 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. dusk, avoidance of the building was designed as a passive house. that means its air tight and the energy it uses its generative. what 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. i saw 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 big 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 in a way that after the life cycle of bidding, you can actually remove everything and we use it or throw it on the composites. for starters, the structure itself used to be the loading haul of an

o brewery. everything has embedded value with this. this is doctor near monkish on a professor at the national university of singapore and an expert in 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 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, a 100 percent organic, so this is just plain and behind the clay 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 and was actually assembled as coffins we disassembled them and just like both these meetings out of that are all very cool, but how many of us have access to the people running you go 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. 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 are there more companies?

because it's 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 structure have been able 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 met. she's the head of the german green building council, and she spent most of her time reminding developers about the cultural climate context where the buildings are happening and that the 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 a 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 response to a 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. earnings after 3040 years have been 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 to what's 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 sol, obviously province. that was devastated by a series of natural disasters in 2018 face for the mammals task of rebuilding. it rediscovered a traditional material which it turns out can withstand natural hazards far better than most conventional 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 palo 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 details shows similarities to original cloud houses. yeah. called gum period buller noah b. there are slight differences. most people to day are only familiar with lobos and assume these new bamboo houses are like them. and yet the open house, even in fact, these houses are the same shape as old rico valley houses. but i meant to 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. at that, i'm glad 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 romeus has worked with marwan and his friends for several months and we see that 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 at the at that means and additional to rebuilding homes for disaster survivors. we can also

provide economic benefits for those who have joined the training program and the the sun. bamboo houses do still, however, have an image problem. according to rama sana, he's the director of the central solar ways a carson institute, which is implementing the bamboo housing project in partnership with architecture some faulty indonesia. dallas is simpler than kamisky nandita on poverty conducted by social and statistics agencies, including certain indicators on india. got one of them is the material that people use for their housing. ah, not the real em dual duncan with the use of anything other than con, grant. as seen as an indication of poverty, latin buckle, but on it, luciana, must such categories affect way. we see things. don't go more than mumble, 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 and um health center. my one plans to move into his new bamboo house with his family soon and he's proud of what he has learned along the way. they do 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 state you 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 and bennet in 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. leather brainchild of swiss architect peter fetch who invented these earth houses over 40 years ago. this is done. it's just a logical solution in terms of environmental protection, integration and ecology. hill. the color all 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 here there is 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 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. those a coat. the house has curved walls, high rounded ceilings and fanciful paintwork. the rooms fused together elegantly

habit ovation has been living in this earth house for 31 years. he was fascinated by pater fetches, designed from the 1st time he saw it lengthening and b. o man, 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 indeed is he steam at us, glided 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 that i know there's a returns in nature to simplicity and why all these expectations people are born from the womb after all the rest of it just felt like no clue. why do we keep building everything square? it died? 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, this is about this building method involves very few materials. i don't need to be all that precise. i'm not fitting boards down to the centimeter. so i can follow my intuition a lot more. 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 codes he also ouster can lease earth houses are ahead of their time. but more and more people are taking interest in alternative living concepts. led to side of a slightly 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 gave lou will our understanding of architecture change? how can we live more sustainably, pater fetches design may provide at least partial answers to these questions. could you imagine living in a cool, like the one you just saw? that 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. stay tuned and we'll be back next week from an entirety. good bye. and thanks for watching. ah i ah ah, ah, with

you oh oh, who doesn't know that a band that has reinvented himself again and again since the 70s. what is their secret?

look behind the scenes of what is probably the most famous band in the world. barked 21 in 30 minutes on d w. and what's going on here with who do they think they are? good questions. you can find the answers here. oh again. all the goals. the point is that you got highlights 20 minutes on dw. imagine how many portion of love us heard out in the world climate change in comp, the story. this is my plan, the way from just one week. how much was going to really get

we still have time to go. i'm going all with hello guys. this is the 77 percent the platform for africa. you beat issues and share ideas. you know, are these channels we are not afraid to. young people clearly have the solution. the future. the 77 percent of every weekend on d w. a a
