ah, a ended glistening place of longing, mediterranean sea. he had almost roar and to fall dockery drift along, exploring modern lifestyles and the mediterranean meeting people are hearing their dreams ready to me journey this week on d. w. ah. are cities accruing 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 little bit. we have several coming up contribution. hello. welcome. to eco, india, i'm some of that i go 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 waste. ah, in furnaces such as this one includes rot, metal is melted at $1500.00 degrees celsius and cast into radius 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, um o. laundry dust is actually o hazardous, medieval, which is a byproduct of industry on so many times contains messages, heavy measures which can be how well, especially for the flood realty, all the sign as well. the walk up because this is disposed off without i mean in or one space. and if it comes and going backwards really walked up, especially rendered 3. and then what would happen is that if we get into the site, this does the flexibility of the site and on. so going back to the ground water monies what, how do you want to come mean the good rap,

the city of fun and that seeking ways to address this huge waste problem. we walked down the bridge in europe. in fact, we will find open dumping all the time and we've been all over this problem is leaving as the industry if foundry dust is collected and combined with plastic least in a 7030 ratio, you get this a silica plastic block for money's quote, hardy themed up with up psychos decorah of a recycling company in on and to create the 1st silica plastic blog in 2018 each lake. our last big block starts out as a dry mix of crushed plastic waste 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 5 mot could 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, how do you have found ways to recycle raised in more places to what area do you everything up with the problem when you have everything of a problem. so the waste is also relevant. this isn't done. so we have no way 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 problem,

trying to get your phone calls and get people on the model x one. they would add this construction site 9 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 go to many a 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 part boring book just 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 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 into the silica plastic blogs and also 2 and a half times stronger than regular breaks of the same price for the port heidi's

work has also reached this farm in the bible office. we're stuff will continue this last period, but anything that is collected does not, then this must them. the top are going to start collected. the collected plastic least is transported 35 millimeters of a ana and 40 thank ling, their plastic, separated in preparation for processing with the foundry dust while up cycle tucker 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 no may not be over to you so we can or dish and money is good, 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 us 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 2 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. that 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 leanna, 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 pad that shows you how much energy the building is producing from its solar panels and when it also shows how much energy you're using and how that sucks up against her. so called budget of this,

we're warm water too, and there were a bit over budget because the kids pay past due like taking bad. 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't ha, which is good. i think, you know, i think this whole thing is a bit it gives it's sort of a competitive fuel. while it's actually sion, the dumb 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 mosquitoes 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 avoided the building was designed as a passive house. that means it's air tight and the energy it uses. it's 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 there to 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 dr. near monkey 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 ford, which will have a flat that sure, a large common area and kitchen. so here you see we big 100 for with what, nothing is. nothing has glued its own food. so you can remove like legal crude, a 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 and was actually assembled of coffins we disassembled them and just like bo this meeting moved out of that are all very cool, but how many of us have access to the people running? you go show sourcing cycled materials, 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 is it or more of that company?

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 le map. she's the head of the german green building council, and she spent most of her time reminding developers about 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 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, it's actually the wrong strategy and a strategy is through 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 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 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 mammals task of rebuilding, it rediscovered a traditional material which it turns out can withstand natural hazards far better than most conventionally building substances. central soon away 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 7.4 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 of structure used as a traditional meeting in place and it's been it, but the details shows similarities to original cloud houses, yet called gum period polar 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 little open house, even 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 will never do. there are also ecological 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, we store 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 sana, 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, dallas, she still 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 a con grant, as seen as an indication of poverty, latin buckle, but on it, the governor must such categories affect the way we see things don't go more than mumbo nodded perception, myself, but he does. 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 im health center my one plans to move into his new bamboo house with his family soon and he is proud of what he has learned along the way ahead of 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 hospital 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 bennett 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 pay to 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. leads to mush 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 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. rich does she coat? the house has curved walls, high rounded ceilings in 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. they didn't 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. 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 health and 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, the, and 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, deep dive. 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. i've had to build houses a bit like a kid to 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 til 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 house through can lease earth houses are ahead of their time. but more and more people are taking interest in alternative living concepts led to size. i was 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 with will our understanding of architecture change? how can we live more sustainably? pages such as design may provide at least partial answers to these questions. could you imagine living in a look who like the one you just saw that on a lot of realities to consider before taking that lease? and that's why we have eco, india. we continue to give you perspective about the why in the hope of going green,

sir, do you want and we'll be back next week from our entire team. goodbye. and thanks for watching. mm. a with ah, ah, with
