and somehow stay a nice the nice you get their hosting for america. and babies shuttle stops oldest on d w. the, did you like to dig into stand 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 is 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. 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 how 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. 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 pouring of the concrete, the concrete will be poured non stop for 30 hours. that will mean tens of 1000

since of tons for one segment alone, then starting the rest of it here. the key is to for each element in a single for you, that doesn't mean doing the floors. that'd be 1st as usual. and then you've been doing the walls and then the ceiling, dick, them the we concrete, the entire segments and one for because we have to make sure the temperature stress is under control to avoid crack loan. and the problem is with the 2 of them are that becomes critical in water type construction, reducing constant. so i'm not totally here. you get this, then 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 big recognition for the many hours that have been put in to get here from the business side to our designers helping us in the construction organization at one done and the whole framework that surrounds the old noun ibis vehicle i'd be pass opponent to on the tunnel will consist of a total of $89.00 pre fabricated components with chew tubes for trains a to, for cars that make a 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 ratios. but it will only be a very small part of the total reef 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. you next denmark with northern germany. it will save real travelers and con drivers, 160 kilometers of driving distance. it's part of an e u project 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 to pay off. the estimated construction costs are 7000000000. yours was the number one to find that our assumptions are based on a traffic for cash that says we can expect to run a 111 trains in day on. and that's also what our financial analysis is based on weight. and we also assume that around $12000.00 cars, we use the same mind without the tunnel from 2030 onward month. it's 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 or at least another 20 years. more important is the safety of the mega project method, as toner. 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 of i'm so the is a safety buffer. it's really not a problem. the event is done hard and 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 us army base. it is, 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, and even had american fast food chains you couldn't find in the rest of germany. but after us troops relocated to a nearby v 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, here are my, we have an urban mining concept us. it's based 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 heidelberg deputy mer and heads up to the city planning department board and fair. really are lots of resources here. and we want to value these materials and use them to build the new district to interrupt type on. roughly one 3rd of the buildings will be left standing, gutted and renovated. 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, it 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. the photos will be

tough, so all of this represents a new approach to old buildings and goods improving how we build things as vital construction accounts for 13 percent of global energy related carbon emissions. and it's not just about putting up buildings. buildings are demolished, they usually end up in landfill, all told construction and demolition to 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 cards 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 like 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 look 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. this information is track for the whole neighborhood with a breakdown of all 500000 tons of material. look, i know this seems a bit try, but without any of this documentation in all of these databases, the actual mining of urban mining is remotely possible. color vin mining sometimes called circular construction is a new term. and as we get on the 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 shell and focuses on the built environment at dutch sustainability consultancy, metabolic during the most target solution. and 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 medical it's 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. they're just starting has many empty houses, office and 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 settlements, have been, have had several lives before the end up in um, in these informing areas. and how to bag this process is a lot more bureaucratic, painstakingly documenting every tile and 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 the real fun begins on 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 builds 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 degree. 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 in part combined with new concrete, some of it will be used as the base. i st. said 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 some 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. 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 an architect, this whole process to be more of a assembler of materials. instead of a design, there was

a building we'll 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 this route. we have to be incredibly careful them that none of the materials we collect here are technically considered waste. then it becomes a whole big thing and the 2nd that happened on the specific companies are allowed to handle that, say i, and then this was on and so on. and with an individual or a big binding project starting to pop up all or is it a 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 bags, 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 constructs buildings. 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, but can be used to build aircraft engines. for example, get free the printers could soon make laborious slaving a thing of the past. 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 a waste, 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 is on is on the super easy to use. so later on in the face and

basically what you do here as you load your pods. once you have your pod loaded in the location, we want it to be. then all you have to do is close the bill on test print, and you get all of the process information down here. you'll have your printing from it. it's up here. so far they have sold over 303 d printers to industrial customers. the costs per machine around $200000.00 heroes. they were different versions like this compact printer. for this one with a robotic arm, which can produce very complicated shapes. many companies today elect 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. for the laser printers use this metal wire is of different calories, which are set by a wire spills. however, printers are not able to produce all al, always have specials, steel and the object size is limited. the middle po, company is located in northern under lose the media nowadays, and impoverished former mining towns. the inventor of the technology chose this location because there 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 somebody use the objects that their printer is pretty

as ship propellers, injection nozzles, such as in the chemical and food industries and the pipes for gas as 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 design and that was able to be manufactured into a component. so with our romantic integration system, then within a design machine, 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 the top and then we will cut the dog for my senior house. and the company is profitable, but the profits are not paid out to investors. they want to reinvest all surpluses

items is to become the reference. and so i change, you can call them at approximately function the wealth and to know for this we need to grow. 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 put one 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. so if you live in pakistan and or a woman, you might find that you also need to think outside the box,

the 1st profession. so just the tickets why? so the army thoughts are like if it was this argument, fission design, and one on the or minimum of non business stock than that. now with the caught up in advance as documented the, the things they could still either be for the, the, she was an export or, or one of the 2 successful business woman. the money that is the 1st well most name business woman has and that will fit taishan with the key idea of when the case or a brand new or packaging thing on the face of men markets many keys the

mid and i'm of show her a so i'll be c, be long could 0. i am in and tripping the industry and these that are founded in seo fast, most packages, the goal, but how much that's almost 4 months. said that if they were minutes, so it took to make one so, so, but on don't have them at a cost us manufacturing the whole cardboard boxes be available. hope wisdom, us giving you will scale up everything. services, several brochures visiting card, so sorry i was still filled under one roof on go. so do you send mrs me that the and i'm a w i uploaded the phosphate the one on them with a guy. ma'am you have them other than this, you need to last example. all big female business talk you with the install. ok.

minute. good. star. key at the subsidy. what almost the financing code, the what? the, what the of home bank is that policy up ma'am. uh, which funding or financing any of the want to get it one more, more visual be you'll get somebody 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 will get going on will be made it possible for all of us so many up now going to say he's got to get with unity. 30 need be towards us darky. i thought the label to get that. i'll be gone. kia x, all the size of the label, guess all kind of machine picks are they ok? the last 2 minutes sick?

nick, a law. how to to walk you through the gain p for 10. does he have any ation, metal dealbreaker? someone can designing, told them what a little was for the kids because of the oscar little mini possible thing, guidance and they give me the last few as they have them. thank you one that of nikolai or profit to be how may have was sort of the may the bus 2540 time employees have like again the money and we'd get her last name for the sake of an instability. hyper installation, but we'll see what else again business made up of 10 don't. so i did it in the why didn't i feel better? how about angel focused on the question a i don't have money. no look, a mindset hit the little upset of breath when he care. that's a lot easier to get you off of what the and hey i thought teaching me that you have

to dr. but a so you do proficient. so i'm going to get yourself. so i'm just thinking one for a simple the woman not into the business is to, is pick on and that's, or you can go on mental or bulky. that'll build a woman's 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 maybe and click on that to you. and i want to become one of the successful amino and this, this woman of a focus on the bottom most likely this fall on the 8th, the 15th of august month. and the student with the that's out through a 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 anyone can

internationally met and is here to see them. that's already all women and follow them and feel the skill level elements become 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 pin out there will be so many within circle going to email is the whole disco guidance. he said, well that's all just met of the industry level ending or the step next to it. as a business start to know i do provide them to commit. they will have 2 people. the that's it for another edition, it's made the double use business magazine where we dug deep for the world's longest vendors. the tunnel checks out urban mining project and saw how 3

d printing could revolutionize the metal, working industry. plus, we met a groundbreaking, women entrepreneur, keeps thinking outside the box. and we hope to see you next week. the
