for mines, imagine how many portion of lunch us her and out in the world right now, the climate change, very hot. the story. this is my flex the weight from just one week. how much was going to really get we still have time to go. i'm going all with what 1st his subscriber all morning was like oh 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 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 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 with ah, in furnaces such as this one includes rot, metal is melted at 1500 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 oh, hazardous, medieval, which is a byproduct of industry. it on so many things going things matches have measured, which can be hard, especially for the, for going to be all the science as well as the water. because this is disposed off without i mean, in all bun space. and if it comes and gone backwards really walked up, especially rendered 3. and then what will happen is that we finally get into the site. this does the flexibility of the site and 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 race problem, walk down the bridge europe. in fact, we will find open dumping of time and waste. and all of this problem is leaving as the industrial brain if foundry dust is collected and combined with last degrees in a 7030 ratio, you get this a silica last big luck. for money's quote, hardy deemed 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, the glock starts out as a dry mix of crushed plastic waves and foundry. does this make sure it is put through and extruder and comes out the other side in the form of a slutty ready to be moulded into any shape or size required with inside my work or add up cycle. jekka takes pride in turning heaps of waste into something useful.

hi am i? my mother invites it. you can make something like this from plastic. surprises that 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 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 whatever you have to think of with the problem when you have everything of a problem. so the waste is also relevant. this is the we have no food, then we can work it up. it's a lot more than it can be picked on. when people are you can take it to one poll,

them trying to get your phone call them, give 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 forcing you pink off in the water, you for securing goodness, 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 walker, 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. what does what,

how do you work has also reached this farm in the bible office. we're stuff will continue this. not picking it, but instead of the 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 transport date, 35 kilometers of a on and 40. thank ling. their plastic is separated in preparation for processing with the foundry dust. while up cycle tucker mostly produces bricks for construction. they create custom product to the ad, to form sauces, to liquor, plastic glove, service, flooring, furniture and even stationary. so that's not, is not, not based on the t. so we cannot asian 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, my 2030. the you, when 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? our reporter set off from berlin to find on the 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 industry accounts for almost 40 percent of global c, o 2 emissions that makes the pace of urbanized nation pretty alarming. when we heard that one of the world's biggest energy plus permanent 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 lola. 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 this is the, well, the energy center of the house, so to speak. every flight 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 would the weirdest thing about this whole thing is, is the ranking over all $74.00 units of the house are raining 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 a bit it gives it's sort of a competitive fuel while it's actually sion down humans, new competition for change to happen. anyway, the main question is, does the i pad work that we 1st moved into the public? 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 $60000.00 euros a year. living green is inexpensive privilege here. and, and just because the building has green doesn't mean all its residents are normal

people in here. i mean there is head, 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 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 16 make team 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 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 comes up. so what does that mean? when we say we the circular? there are 2 main aspects. this is simon lee. he's the head of the circular house project. one is big from waste, from secondary resources, basically. and the big and 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 hall of an old brewery. everything has

embedded value with this is doctor near market 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. sure, a large common area and kitchen. so here you see we big 100 percent with what? nothing is. ne, nothing exclude. it's all screwed. so you can remove it 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 installation compress the straw up cycle plywood and create a natural alternative to concrete made of 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 light thick 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 to 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 it is more difficult,

you need to put in the extra work to basically analyze the building. what can i do with what kind of resources structure to have enabled 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 death and cultural climate context where buildings are happening and then 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 career men 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 pointed to a 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 being torn down and being replayed, quality was not good at modern and anymore. but whether it's 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 in denisia now and the community in central. so let me see proven that was devastated by a series of natural disaster in 2018. based for the mammals task of rebuilding, it rediscovered a traditional material which had tons out can withstand, naturally have a far better than most conventional building substances. ah, the central silhouette see is no stranger to natural disaster in 2018. the province was his science who nami landslides and a series of earthquakes, including one with a magnitude of $7.00. bull on papa was one of the many villages affected in we district, an area that's popular with tourists from palo city to gather with the organization

architecture some frontier, indonesia, a group of young men are now rebuilding flattened homes from scratch with bamboo. it's also hope the project will for find economic stimulus that's affiliated with the theme. and then at a glance, this looks like a logo, a structure used as a traditional meeting and place listening. but the details shows similarities to original cloud houses, yet called gum period polar know off b, there are slight differences. most people today are only familiar with lobos, and as soon these new bamboo houses are like them and yet little open house. in fact, these houses are the same shape as older cool bough. we houses, america, and my main motivation was the need for shelter. we were informed that besides getting a house, we would also learn skills that that would be like 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 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 restore damaged ecosystems in the region. most importantly, bamboo is very interesting 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 carson institute, which is implementing the bamboo housing project in partnership with architecture. so volunteer indonesia. the alarm system found out on 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 con, grant, as seen as an indication of poverty, latin buckle, but on, as the governor must such categories affect the way we see things done, go more then mumble 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 used 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 is 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. i wonder what it would be like to live in

a hospital then state you because on next report explores the walk of swiss architect me to wish who's 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 whole than a convention home. but its aesthetic 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. their color who normally houses take space away from nature. here vegetation can grow and the earth covered roof and the house smelled harmoniously into the landscape. is too much been so easy as

a 50 centimeter layer of earth. but the cover increases in depth. further up on the top, there is a $120.00 centimeters of earth, and 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 to reach those a 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 pate of 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 the dust glided cream. all these stone carved houses in tunisia or these and cap and osha. turkey serve as inspiration for pay to fetch. he built his 1st earth house in 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 you have done, it just felt like will click, 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 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. build houses a bit like a kid 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, fixed and blah, blah. he know the codes 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, lids, ties. obviously, i've been getting more and more requests. people are paying greater attention to the environment and they realizing building a freestanding box isn't environmentally friendly. we gave, hulu. will our understanding of architecture change? how can we live more sustainably better fetches design may provide at least partial answers to these questions? could you imagine living in a know 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 have eco india. we continue to give you a perspective about the why in the house of going green,
