also forgiveness. i'm sure. guardians of trees, julian, his sons, and the dark secrets of war, starts to lie 27th on the w. the did you like to dig in the sand as a kid, build castles and houses assembled model airplanes or play with cardboard boxes. then you might really enjoy this week, so except here everything's much bigger and way more exciting. we'll see how it works, progressing on the world's largest underwater rail and road tunnel. a new way of building using urban mining to recycle old houses. a 3 d printer that produces precision metal parts and a pack of stanny entrepreneur who makes cardboard boxes.

these are the 1st finish parts of a record breaking project, the world's longest pre fabricated tongue. that'd be fine. it's an important project because we're bringing northern and southern europe together. the very 1st section was dedicated by the danish kings. that's so important. the project is and doing came today. it's a huge day and an important milestone for our final goal of opening a tunnel to germany in 2029. can you provide the? it's a project of superlatives. to build the tunnel, europe's largest construction site had to be created. the largest gloating drudgery in the world is also being used here. welcome to europe's and mega project with mega challenges still to be overcome. a critical moment during construction, the poor and of the concrete. the concrete will be poured non stop for 30 hours. that will mean tens of thousands of tons for one segment of the on the inside. and

the rest of the key is for each element and a single floor between the that doesn't mean doing a floor slab be 1st as usual. then you've been doing the walls and then the ceiling to come up, but we concrete the entire segments in one point because we have to make sure the temperature of stress is under control to avoid crack loan. and the problem is with a 2 by my and that becomes critical in water type construction, reducing constant. so not totally here. you could, this van things went smoothly with the 1st pre fabricated elements. each is 217 meters long and 42 meters wide to name store and it can be, it's big recognition for the many hours that have been put into get here from the business side to our designers and some of the construction organization at one done and the whole framework that surrounds the old need and all of us vehicle i'd be pass opponents. who on the tunnel will consist of a total of $89.00 pre fabricated components with chew tubes for trains a to for cars. the mega components will later be sunk into the sea and connected

that will be followed by the interior work. because we know that when we take the trench, we will destroy some rios, but it will only be a very small part of the total rece area. then for just 0.05 percent, and actually many times more rates will be rebuilt in a different location than will be destroyed. noise has upstairs the tunnel book and next denmark with northern germany. it will save rail travelers and con drivers, 160 kilometers of driving distance. it's part of an e u projects that will make rail travel between northern and southern europe, faster and air travel redundant b e u project also includes the brand new base tunnel which will connect to austria and easily at 64 kilometers. it will be the longest railroad tunnel in the world. back to denmark was a project pay off the estimated construction costs are 7000000000 euros with

the and the wonderful enough, our assumptions are based on a traffic for cash that says we can expect to run a 111 trains a day. and that's also what our financial analysis is based on weight. and we also assume that around 12000 cars we use the same on the tunnel from 2030 onwards. a total of 73 year olds per car is expected. the price squared trains is still unknown. what is certain is that the construction costs will not be recouped for at least another 20 years. more important is the safety of the mega project method us to know if water were to penetrate the middle of the tunnel, we would have a real problems on the walls are designed to withstand a train or car accident and maximum speed. so there is a safety buffer, it's really not a problem for you when it's done, husband on the sample being the tunnel is due to be completed in 2029. incidentally,

the things are paying for it all by themselves as the project is obviously more important to them then to the germans. did you know that you can build houses from recycled plastic waste or even whole plastic bottles? even the fuselage of an old airplane can be turned into a home. 3 cycling is all the rage at the moment. and it can be done using material from houses that have been demolished. the concept is known as urban mining and we'll show you what's behind it. built in the 1950s as part of the us military's significant cold war presidents in west germany. patrick henry village, was an american island on the outskirts of titled like many u. s. army base it as it was basically its own little city, with housing for thousands of soldiers and their families, schools, a church,

a bowling alley, and most importantly, that even had american fast food chains you couldn't find in the rest of germany. but after us troops relocated to nearby the spot in in 2012. patrick henry village became a ghost town, leaving behind thousands of american appliances and even outlets. since then, the jury is only been used in part to temporarily house refugees. the city has grand plans to redevelop the village into a shiny new district with housing for thousands offices in green spaces that would typically mean mass demolishing and getting rid of these old houses and putting up entirely new ones. but old buildings are only a problem if we see them as such. yeah, yeah. and like we have an urban mining concept of taste on the idea of a circular city where we treat everything left behind here as though with a mind. i can be sweet in a minute and basketball, the guy from voice you're getting a chuck is hydro bigs deputy mer and heads up in the city planning department. some

water fair really are lots of resources here, and we want to value these materials and use them to build the new district, to instruct type on. roughly one 3rd of the buildings will be left standing, gutted and renovated as the rest will be taken down to make space for a denser neighborhood with mixed use buildings, not just housing. but the special thing about this project is that instead of sending the deconstructed buildings to landfill, the goal is to resell for use or recycle every thing that you can see here, from literally the ground floor windows like these could typically be used for changing energy standard since these were put in means that they can't, they tend to be recycled a tricky process, but it's possible concrete can either be used or recycled as well. but then we've got to find a home for all of these big old american fridges in germany. all those will be tough cell phone. this represents

a new approach to old buildings and goods improving how we build things is vital construction accounts for 13 percent of global energy related carbon emissions. and it's not just about putting up buildings. when buildings are demolished, they usually end up in landfill, all told construction and demolition account for about one 3rd of all. the waste in europe. projects like the one in the heidelberg can do their part to change this, but it didn't actually start here. it started in an office and stood car about a 100 kilometers. so the 1st step is actually to, to get an idea of what do you have to sign which works for e t a, an environmental consulting company that's partnered with title back to build a database of the cities building stock, starting with patrick henry village. so you need to know exactly how much material you have, what is the properties of the material or the hazardous substances. for instance, you can estimate of buildings construction materials based on its age and location

and its data base hope. so these i titled may i get a sense of reusable and recyclable materials at their disposal on planning new projects titled back then confirms the estimates that means boring holes in the floors walls and ceilings and making a checklist of everything looked hanging around the former base it shows you that over 52 percent of the building is ex, the concrete in around 5 percent. this metal. and this is like a 1st overview of the inventory. me. this information is track for the whole neighborhood with a breakdown of all 500000 times of material. look, i know this seems a bit try. but without any of this documentation in all of these databases, that'd be actual mining of urban mining is remotely possible color been mining sometimes called circular construction is a new term and has begun to take off in the last 5 to 10 years. it's not

a new principle up until the industrial revolution actually urban mining was very common. me go shout and focuses on the built environment at dutch sustainability, consultancy, metabolic during the industrial revolution. i think that's what we see with a lot of production processes. that production became cheaper mazda assumption became more common and we kind of let goals for using what be already have metabolic urban mining efforts include partnering with cities, architects and construction companies. i think a very interesting case that we worked on is the building of the dutch national bank. the 14 story skyscraper was entirely disassembled, metabolic, are working with the developer to design a new building from the secondary materials. they've also built in the office park of old house boats in the global south, for example. there just aren't as many empty houses office as in shops and some of the global north. but in a way, urban mining is pretty big here. even though people don't necessarily call it that when you think of informal sacraments, for instance, they are very set, you know,

in that materials that have been using these informal supplements have been, have had several lives before the end up in um, in these informing areas. and how to beg this process is a lot more bureaucratic, painstakingly documenting every tile in an entire mini city by color may seem a little bit crazy, but you never know when it might help. and that's not even the hard part. it's now that's a real suddenly dens and the things that can be directly reused will need to be sold. we've got 2000 complete kitchens and i don't know how many built in cabinets . we've got sockets and toilet bowls and sinks, and the faucets, you might be able to reuse the process of having the buildings themselves will have to be picked apart. and then you need to figure out what to do with the materials. take the $90000.00 tons of brick and patrick henry village, most of that will be able to be reused to some degrees. but for the 230000 tons of

concrete, it's a different story to then we'll definitely have to process the concrete is combined . it will be broken down and enquired combined with new concrete. some of it will be used as the base our streets of those are some of the different utilization as we've developed, vague, and we've had to do that for every single material. yeah. you know, that's an feed up. even if we start cataloging and mining our buildings on a grand scale, will never be able to entirely eliminate the use of new building for us. it's not just about how we deconstruct what's already here. it's also about rethinking how we built to, usually in the building, you design a building and then you find materials that fits. but if you have to design and with a set of materials, then you really have to shift your way of thinking. i really have also a different position as the architect this whole process to be more of a assembler of materials instead of a designer of the building will need to use different materials if we want to make

future urban mining easier. with that in mind, it builds with materials that are prime for easy reuse, pencil all of the, and treated wood furniture in their office. they've also designed a circularity passport for new buildings that logs materials for future reference and tracking. this data could soon be a requirement in germany, despite the different contexts, lessons from these projects could be useful all over the world. but to make this happen in the 1st place, they just might have to cut some red tape, which is something heidelberg planners know all about the listen route. we have to be incredibly careful them that none of the materials we collect here are technically considered a waste. then it becomes a whole big thing. and the 2nd thing that happened on these specific companies are allowed to handle, that they are in guns, which was on and so on. and with an individual urban mining project, starting to pop up all over the place, governments will have to help coordinate these complicated logistics. and they'll

also have to step in to help overcome what might be the biggest challenge cost, incentivizing urban mining and making it cheaper will help drive change, but it will still take time. projects like fido backs, patrick henry village re development or a start. but also show just how much has to change to get with an a smith of those goals. 3 d printers are now being used to construct the building. all kinds of different plastic parts are already being printed and even exact copies of sharks and can be made to deter trophy shark hunting. but what has seemed impossible for a long time printing metal parts that can be used to build aircraft engines. for example, get free the printers could soon make laborious, leaving a thing of the past.

a small technical parts that is required for a very large machine. like for gas fired power plant turbines, the technology consists of thousands of these precision metal parts. to do this, to components have to be mailed to the 9 a meter and made to fit but one spanish company has an alternative. their metal parts come out of a printer ready to use with this kind of technology replace conventional production in the future. this is what they were 3 d printer for metal looks like. and that's what it can do. the experts call it additive modeling. that means that no material is built away, but the shape is created by permanently applying new layers using laser technology . the idea came from lucas hop out for us when we really want this, where the machine that it's autonomous and the super easy to use. so later on it

size and basically what you do here is you load your pods. once you have your pod mode and the location we want it to be, then all you have to do is close the bill on the test print and you get all of the process information down here. you have your printing from is up here. so far they have sold over $303.00 d printers to industrial customers, that costs per machine around $200000.00 bureaus. they were different versions like this compact printer. for this one with a robotic arm, which can produce very complicated shapes. many companies today, lack of a specialist who can still do this. a lot of problems that our customers are facing is trying to replace a specialized workforce that doesn't exist anymore. and some of the more traditional jobs, but more and more industrial customers want to make their own spare parts. and printing is the solution. however, this takes time. it can take up to 20 hours before

a part is ready. the laser printers uses metal wire is of different calories, which are set by a wire speeds. however, printers are not get table to produce all eloise of special steel and the object size is limited. the middle po, company is located in northern under lose the, in the nowadays, an impoverished form reminding count the inventor of the technology chose this location. because that was already a company here in spain that specialized in 3 d printing technology. he was able to benefit from this, such as in marketing. according to the startup, it's precisely because of the high unemployment rate of around 30 percent. that it's easy to find new people who thought about is a really small team. now a 100 people. and you know, i'm going to say every week that somebody use the objects that they're printers, produce, ship propellers, injection as also such as in the chemical and food industries and pipes for gases,

ends, liquids. the printer's can print up to 2 meters in length owing to parts such as this exhaust pipe from a car manufacturer. and this is a very complex of design, and that was able to be manufactured into a component. so with our logic integration system, then within a design my seen a machine processing is what the head of technology means by milly. the company is developed a 3 d printer that can do both printing and then milling and polishing until the printed parts are shiny and as smooth as glass. this is a, the, the base place where we start to put anything on top and then we will cut the dog for my senior. the company is profitable, but the profits are not paid out to investors. they want to reinvest all surpluses

. i'm just to become the reference and so i changed, you can call me at all possible reflection the wealth and to know for this we need to grow up. they don't want to get rid of the old technology, but change the market. instead. these 3 d printers are ready for shipping this one is packed up and ready to go to the us to a car manufacturer that wants to become more independent from suppliers. with a new 3 d printer from spain ever jumped out of a cardboard box or foot went over your head. you can have a lot of fun with cardboard boxes. but you can also use them to build your own business. for instance, to set up a company that manufactures them that way if you live in pakistan and or a woman you might find. but you also need to think outside the box, the

of the 1st professions or just the but taking the life of the army. ringback thoughts, thoughts next? step in with this argument, fission design, and one on the or uh meant end of non business start going up now would be caught up in advance of stock in the positive. nothing. they could still either be for the she was an export or, or one of the 2 successful business women, the money that is the 1st well most name business woman has and that will fit session with the key idea of when the case or the branding or packaging the face of man markets, many keys made

and how much ahead. so obviously the loan could 0 and enter for the industry. and these that are founded in seo fast, most packages the so but how much that's how it was for 4 months to minutes. they were minutes so it took can make one still so, but on don't have a minute of cost us manufacturing. the whole cardboard box has to be available. whole customer skinny, it will scale up everything, services, stable brochures, visiting cards, so sorry i was still sub under one roof on go study services. me that the good now may be like the blue phosphate. the one on i'm with a guy, ma'am. you have the motor, the industry need to last a good, all big female business talk you with the install. okay. minute,

good star key. i thought the subsidy. what almost the financing got the what? the what the of home bank is a policy up there of which funding your finance and gave me it. the only beautiful edmond more mortgage will be to get her money hold up in real estate properties on the got the, the money has been going on will be done by the father's going on will be at the brothers were good economic. this made it possible for all what all so many up now going to say he's got to get wishing that eats or do you need the towards starkey i thought the label to get that i'll be gone. kia x on the side of the day, but it gets all tired of machine break. are they ok? the last 2 minutes sick? nick, a law. how to to walk you through the game p for 10 dizzier

radius in middle, the biggest, the monthly designing told them what a little was for the co code of the oscar little mini pulse i think guidance. they make it a lot. thank you. when you set up a nikolai or profit to be a man who was sort of on maybe bus 2540 time employees here. but again, the invoice getting a lot of political instability, high for installation. so we'll see what else? again, business man of up 10, don't. so i did advance the fan. why didn't i do better? how about angel focused on the question a, i don't have money. no look, a mindset hit the will of set of breath when he care that they can not easily get you off all of the, in a, at the beating me that you have to dr. but

a so you do proficient. so i'm going to get you on save some of this. thank you one for simple. the women not into the business as though it's become so natural. you can go on mental or bulky, that will build a woman, cannot sit up to an e commerce site or walk you to a business. is it just ma'am? i do already whole lot in handicraft, so guess, well there's a heart care industry insight. they'd be on clicking on that to you and i want to become one of the successful amino and business women of a focus on the box. most likely this. well, i'll get it the so 50, it's all focused on thing. this didn't with the that's i'll do a quote female on in this be getting on the 5th. and i want to become a role model for other females of my agents. not only nation and even going to nationally met and to share this with. and that's how the old

woman and followed him and filled the skill level elements pick um. couldn't make any or a be good and could it be to get man for the programs they would have to buick at me for women and to been out there will be so many within circle going be female is the whole disco guidance? you said, well that's all just met up the industry level ending or the step next to it as a business start to know what i do for them to commit say was up to you the that's it for another edition. if made t w's business magazine, where we dug deep for the world's longest vendors, the tunnel checks out urban mining projects. and saw how 3 d printing could

revolutionize the metal working industry. plus we met a groundbreaking woman entrepreneur. she's thinking outside the box, and we help to see you next week. the

look at us. we 2 off from and so long the sun, muslim women speaking out against antonio in hostility towards foreign is, has become mainstream here. when we hear them, it can feel like we're the problem, like we're not true french citizens when, in fact, frances, also us the focus on in 30 minutes on the w conflict with tim sebastian countries of what's the war and ukraine more closely than poland, which was the time and again, the poor thing was much beyond his borders. no one listening my guess this week it

was all congested, smooth this. i had them both know seals for warnings because the government has to use the same conflict in 90 minutes on d w. the little guy, this is the 77 percent, the platform for advocacy issues and share ideas. the, you know, or the side that will be a north of bridge attacks and they look at the top of the applicants population is really fast. the young people clearly have the solution. the future

is 77 percent. every weekend on dw, the dream of revolution. in 1979, the hate to dictate is the most i was forced out of nicaragua. the people hoped for service society and received international solidarity. i imagine we would change the world and for 1000 republicans had to help with reconstruction. but the end the garage was a dream of revolution. dogs, july 20th on d, w. the,
