with learning, like global ideas, we will show you how climate change and environmental conservation is taking shape around the world and how we can all make a difference. knowledge grows through sharing. download it now for free. with was centuries. new buildings have been a symbol of progress and economic prosperity, but construction today is a major source of waste and environmental degradation in a vsl strap, one should be really start every new project from scratch. join us as we explore the question on eco and yeah, to me, hello and welcome on sunday that i bills demolish,

repeat. it's a cycle that generates mountains of debris around the world, debris that ends up in landfills, a was in the environment. that material actually harbor great recycling potential. india in reels is only amigo, one was sent off with construction and demolition waste. our reporter hid the streets of delhi to find out why ah, the 100 meter high super tech towers in night, a city reduced to rubble in less than 10 seconds. this video is from the guardian newspapers online site. ah, 3700 kilos of explosives were used to demolish 850 apartments. the supreme court ordered the destruction after ruling that the towers had been

constructed illegally. the resulting 80000 tons of construction raised are now being dealt with by re sustainability. it's one of the few construction and demolition res recycling plans in india's national capital region. the center recycled $800.00 tons of waste here each day. bethany, i'm an ard, are 30 for our data mills. okay. we'd been commissioned by the noise authority to process 28000 tons of waste from the twin tower, demolitions assigned a victory of their brother's government process. actor processing aggregate technically we will sell the aggregates in tile form on the open market. we're gonna go margaret number a lot of these won't be turned into a new apartment like in a proper circular economy, but they can be used for building roads and foot bots every day. several trucks transport trouble from the demolish and site to the recycling center. the rubble

includes concrete. the men bored and plotting 1st, the wooden plastic are separated out by hand. then the machines move in. this is our vibrator screen. after the material gets crushed, this machine segregates the materials based on their sizes like 51030 and 40 millimeters. in the construction sector, gender, it's around $150000000.00 tons of waste each year. yet, just one percent of it is processed and used with disastrous consequences for the environment. they set up the and i'm going to say in, in the end the bills on very often through the ground water all the way to do them properly before off through evolution. the 2nd going into the impact it has on increasing the disaster effect offline. a lot of this is very often done. been

rolling, it is in floodplain. what this does is water, is it disrupt the usual channel? oh, what do i prison and that it increases the the severity of blood of psycho and often just under a 3rd of the solid waves produced in india's urban areas comes from deconstruction industrial, building and demolish and raised like this is often dumped illegally. that's what this group of volunteers is looking for on a walk about. so daily murali, neighborhood, the hindi ward for such waste is melbourne. i feel walking along the bed if there's a lot on my lot at holland years from the modem. project photograph the bias of fleece and send the images to the parties to request it's proper disposal. the city both $200.00 collection points and 5 recycling centers for such waste. all these sites are marked on

a digital map created by the mailbox. they're marked with blue and green points for that. and in the end, we have the illegal dumping points on mobile. and these were what the residents would send to us. so they would click photos of which was maybe dumb dough. so their house, we told people that if you see illegally in your neighborhood, please report it to us so that we can put it on the map so that at least we can take it to the m c. d and make a very strong case that here this needs to be cleaned up and then it is up to the municipal corporation of delhi, the em city to take care of it. back in 2016, the federal environment ministry, such raised money be collected and crosses em city as introduced fines for illegal dumping for residence and non residence. it also offers financial incentives to

encourage recycling whenever anybody can sell the house. so we ever started digging charges for the management of the c n d. and the condition that if you will give me the receipt that we send this the weights to the facility, then we will return that money and is a huge money. not very small money. when can they think even then the out, the output, you can see that sex is, is ready. although there are $100.00 collection points spread across the whole city . most construction companies take the easier route and dump illegally. the employ, informal rece, collectors to do their dirty work at night to avoid being seen the risky work is barely even recompensed. their business minded people, they want to save money. they want to make money. they're making that ends meet and illegal dumping does not make it can all make sense for them. they were the other sell their bar to someone who would you it for leg backfiling only when they're not

able to find on that placed or dumped is then out of desperation because they have to do a certain number of trips per day. ah, you know, to, to meet their financial attire, gets to break even. there is still no end to end demolition collection and transportation system for construction waste recycling, cure yet. that's essential for a proper circular economy. there's a long road ahead. and so the mulberry project volunteers look certain to have their work cut out for a good while yet from the outset, most new buildings are not conceived with sustainability in might. now that i'm growing calls for the construction industry to adopt a more soft eula model. and to take its cue from nature where there's no such thing as waste. these german buildings don't only look modern,

but they might also pave the way to a circular future. they're built according to the cradle to cradle concept. the idea is to replace our cradle to grave economy, where we take macon waste with a circular one where the products are designed in a way that its materials can be reused over and over again. normal sophie griffon is the founder of the cradle to create a lab. it's an and gio dedicated to spreading circular regenerative design thinking across industries. politicians and designers welcome to their crater to cradle out . you can come in here. we start here. you see like from the lamps that you can see it from a mushroom material totally for biological cycles. according to the concept, no, it was so fi griffon's. father michel brown got and his colleague william mcdonough created everything we built must go to either what they call the biological cycle

or the technical cycle. that means the materials used to build the products need to decompose, thus becoming nutrients for the soil or dismantled to become what they call technical nutrients and re used in other products to with. so in here, right, you can see a lot of products that are already produced in a cradle to create a manner. this flooring you can see if i move, i can actually take it with me. pretty cool that you don't need to do this. it is made out from the packing material, losing as an a credit crate. not the best idea to do that because quite difficult to disassemble. the lab uses these carpets that are totally made of recycled fibers and not glued. and you can bring it back to the company and they can recycle it and make it totally new. carpet out of lovers of grief on argues that

there are a lot of natural alternatives to most of our commonly used toxic products. this material is quite interesting because it's like a material that you cannot just take from the inclusion and you don't need actually to change it a lot. so called damp tune balls are basically dead sea grass that could be collected on shores and used as a high quality insulation material. all these examples seem perfect and relatively easy to implement, but we need to change the way we have built our homes and priorities for the past decades. 50 years ago, we knew that there are negative environmental consequences if we have certain building habits. so in the beginning be had felt that we require new knowledges to be able to build appropriately. but right now we have a different problem. professor arnold palmer condo is an award winning architect, mostly known for her sustainable projects. like these ones. when standardization is

being imposed, then the must have the courage to question the limits of standardization. and the construction sector is especially standardized and rigorously conservative. some practices haven't changed in centuries. take concrete, for example. it's the 2nd most used material in the world, only after water. if it was a country, it would have been the world's 3rd largest carbon polluter. after china and the u. s. last year, we produced 4400000000 metric tons of concrete. according to the u. n's projections at this rate, we would be producing enough concrete to build the entire city of paris every week for the next 40 years. so that is a lot of concrete. and for several reasons, this material is not widely recycled. a big one is standardized, bad practices says marcel oser,

a circular engineer focused on cradle to cradle applications in the construction sector. if you use a, jay, lester, all concrete uncomfortable is why looks good, so it fulfilled the purpose. i used the quality of the concrete by not being able to use it later. so, gypsum plaster makes the concrete on recyclable. but a similar looking silicon based plaster doesn't affect the reusability of the concrete. or let's look at steel, a universally used material in construction that could have an infinite life cycle . just a simple decision to use bolted connections rather than welded joints will allow the structure to be dismantled, making it easier to reuse the materials. it's all about designing smarter. while these individual solutions are amazingly easy to implement, unfortunately, they alone will not be enough to make the construction sector,

environmentally friendly, says, nor was so fee grief on though we need the market. we need the politicians, and we need this society to go for this idea. and i think we are already in a state where our society sees that we need to do something different. so crater to crater can show the solution how this is actually possible. cradle to cradle is not a miraculous idea. it's just a guide for us to think and build in cycles. just like nature does blue. when it comes to prestige projects, developers like to start with a clean slate. but if a single new structure already impacts the environment, the construction of an entire city is a whole different dimension. indonesia is pushing ahead with an emb slant the z located capital from slam, couldn't a cot. i bought a wanted to move. is that when a good oh, home to over 10000000 people, indonesia,

capital jakarta has a problem. city is sinking by around $25.00 centimeters every year. some scientists predict that the metropolis will be completely submerged by 2050. that's why the government is creating a new capital from scratch dues on tara is being built on the nearby island of borneo futuristic looking buildings covered by renewable energy or no under construction and implementation is sa, paula, or rather than being a model city for thought is asia, it's going to be a distress. the idea of moving the capital was 1st proposed in the 1980s during the c harter dictatorship. but it was only in 2019 that president jo, cool with dough to approve the $33000000000.00 construction of

a new capital on the east coast of borneo. it was the capital is not just a symbol or just the nation identity, but also the representation of the nation's progress to me that this is for economic justice inequality. for the vision of an advanced indonesia. yeah. my to with the move, the president wants to boost development and regions that have been economically left behind. ah, said tara, which will be roughly twice the size of new york city, will cover over 2500 square kilometers in the province of east cali mountain. the area is currently covered in eucalyptus plantations. the government says no protected forests will be touched. according to the plan newson tighter will be green, hyper connected digital utopia in the middle of a lush landscape. it will be fueled entirely by renewable sources of highly

accessible public transportation and 75 percent of it will be covered in green space. it's a massive undertaking. indonesia has shy away from expressing is hunger for one life station and industrialization. it has been taking a very many approach to achieving dream of it from here to the high income country . more than half of indonesia, g d. p comes from java island, where jakarta is located. experts say that moving the capitol. ready is just part of a bigger development strategy, which is to jumpstart, to green industrial economy in the cali mountain part of indonesia. this is why several dams are being built. the government is constructing 5 hydropower stations on the river chaos to speed up industrialization. north of new and tara president with dodo is planning the world's biggest green industrial park. indonesia also has the largest nichol deposits in the world and raw material that the booming

e car industry urgently needs the new capital as part of a wider development plan. but there is the price to pay the move will displace indigenous people, make up 20 percent of indonesia population. at least 20000 people from 21 indigenous scripts are at risk. property prices are already surging in nearby bolick, python and indigenous residents are angry. and bring the roles from jakarta, but these rules don't fit here. we are being offered just a fraction per square meter of the price of land and new capital area. what if we sell? where can we buy land again? anywhere around here is impossible. they are slowly driving us out. gara movie, mika. banu is also home to many endangered species,

including the pr boscus monkey barney and gibbon. and soon doub hangal in the barn in rang a ton in particular, has faced a huge decrease in population and will be severely affected by the construction work. the base will be like a cancellation gate to the capital area, right? if the watergate, the chemical area, if i'm on the same time, it is where all of those protected species are there, east cali mountain is rapidly losing its forest to industries like palm oil and logging. also disappearing our mon grooves, and pete lens, which are important carbon sinks. scientists are worried about the impact of the indirect carbon, an ecological footprint which could extend 200 kilometers from the center. local industries such as fishing that the pen and the mongrel forests are also at risk of being displaced. that america, i hope once it gets crowded,

that the people benefit there will be more jobs for us, and that locals can work in the new capital. with this entire as green plans look great on paper, but there are problems looming. kevin dice actually sitting on the handle of co. oh for of indonesia is 5 biggest cool plants are in east cali mountain. much of the energy from building the capital will come from here, which could mean disastrous pollution. it's uncertain how the new capital can be emissions free by 2045 as planned for talking about beauty intensity. and it's the address. yeah. michelle, from us, russia materials as well. only 11.5 of indonesia, national energy is renewable. solar and wind power are planned for new san tara, but no one knows exactly how it will be implemented. everything is fi answers at many comes to this and i've not even really. ready quite natural to consider the

resources they have like this hydropower and they hope all months to power the city the construction of new centera has only just begun and is expected to take another 20 years. but the scorecard for cities built from scratch is patchy. brazil's capital brazilian ended up notoriously segregated me in mars. ne p dog is mostly a ghost city. and in nigeria, a boucher lack of affordable housing created slums. and so that was only far a political agenda. it's not going to work a good city if it's a city is an inclusive and, and that is a lie and there is a song in that city until then jakarta will continue to sink. the metropolis remains the capital and economic center of the anesha. it's hard to imagine that this will change any time soon for what good home look like that really,

resources are rely sodden on materials that are readily available. we met an indian architect who strives to cut consumption by embracing such materials as an asset and got a house store in delhi. ah, the new daily skyline is a mixture of modern skyscrapers, and energy intensive, poorly designed constructions. carbon emissions from buildings are often neglected from the climate debate, but in india, buildings alone are said to contribute to 40 percent of energy related carbon emissions. ocoee, daphne london, paval has been designing sustainable functional buildings for over 20 years. he says the need is now urgent, but there are still a lot of misconceptions about what green building design really means. the big gift meant that is that people believe that equity in home is one that has a lot of green plants. you put in a lot of plans, lawn and glass. it becomes green,

which is not so in the green building is actually green because it respects nature . and it kind of uses the lip lanesha will sources early sources and that it uses via stage and it uses consumption and me the cycle. a lot of my ideas, who one above all designs in new delhi, is famous for being in the us. first, 5 star rated green home called green one. the home has been certified by research and policy organization. the energy and resources institute. large windows provide lots of natural light. while double glazing a relatively new feature in india, insulates the building, keeping it cool in, in dallas, hot summers. who have i worked with green one or no prashant, or do i command to make his home sustainable?

one important factor for going green was sourcing local materials. the house also generates renewable energy and harvest strain water to day it is able to capture 75 percent of its water demand and can also save up to 40 percent of its power. at the moment, india has around $1400000.00 modern homes that are built with the green concept, which constitutes less than 5 percent of all residential properties. however, this to distill excludes the countless temporary homes. and those bit by hand is rural india, traditional homes that are often green in the own right. we are always inspired by history has to be studied because

historically, what people have built naturally, it is known that they are the best structures. and what we do is we can temporized it a bit so that we can use the same materials, but in a more contemporary way using modern technology so that it is relevant so that it's easier to maintain it today. move out of innovated, his own house in the year 2000. he was inspired by the traditional methods of reusing and building based on the environment. i used all the broken pages that came out from the toilets. so all that were broken and used in the form of a pattern. and since a lot of them were light color days, it reflect, a lot of heat has been more people can now afford the initial investment. and more indians are getting conscious about the impact of their choices on the environment . they strongly feel that

sustainability has to start from home. and you have to adopt assessed in a belie, stayed before you want to nibble and been building. so i think the consciousness has come in and we have been receiving a lot of calls from client saying that let us simply fire our homes. let us keep more open areas lead to reduce the area that is going for more green major. let's go and plant more trees because they help in, you know, taking care of pollution as well as the link between lost no choice and the environment becomes clearer. architects like bull valley, hope this need will only continue to grow who rebooting the building and living in green holes may not be possible for each one of us immediately. but every single step towards sustainability gulf. don't forget that and tell us how you are going green on eco india a d w dot com until next week. good bye. and thanks for watching.
