also forgiveness. i'm sure. guardians of trees, julian, his sons, and the dark secrets of war, starts july 27th on d. 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. take 3 d printer that produces precision metal parts and a pack of stanny entrepreneur who makes cardboard boxes.

these are the 1st finished parts of a record breaking project, the world's longest pre fabricated tongue. defined. 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. 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 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 thousands of tons for one segment of the on that side and the rest of it here,

most of the key is to for each element and a single floor between you that doesn't mean doing the floor slab be 1st as usual. 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 not too late to 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 it as a whole new and all of us vehicle i'd be pass opponent to on the tunnel will consist of a total of 89 pre fabricated components with 2 tubes for trains a to for cars that make a components will later be sunk into the sea and connected to 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 if there's the tunnel that connects 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 australia 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,

yours was the number one to find out. our assumptions are based on a traffic for cash that says we can expect to run a 111 trains in day one. 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 with 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, 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 i was using because it's really not a problem. the event is done hardly 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. recycling 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 heidelberg. 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, that even had american fast food chains you couldn't find in the rest of germany. but after us troops relocated to 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, yeah. and we have an urban mining concept. 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 hydro bigs deputy mer and heads up. did 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 instruct, 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 standards and things 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. 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 and 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 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 it's age and location

and it's database help. so these like title 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 and the floors walls and ceilings and making a check list of everything looked hanging around the former base it shows you that over 52 percent of the building as 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 that 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 vin 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, consult and see metabolic during the most target solution. i think that's what we see with a lot of production processes. that production became cheaper. mazda consumption became more common and we kind of let goals for using what we 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 supplements 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 sun, weekends, and things that can be directly reused will need to be sold. we've got 2000 complete kitchens and they 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 tons of brick and patrick henry village. most of that will be able to be used 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 in part 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 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 do construct 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 an architect, this whole process to be more of a assembler of materials instead of a design, 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 knew all about the listening roots. we have to be incredibly careful and that none of the materials we collect here are technically considered waste. then it becomes a whole big thing and the 2nd that happens on the specific companies are allowed to handle that, say i and then just as i can, and so on. and with an individual or big binding 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 over time, 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 showed just how much has to change to get with an a smith of those goals. 3 d printers are now being used to constructs 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 for us when we really want this, where the machine that it's autonomous and the super easy to use. so later on in the face and basically what you do here is 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 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 d printers to industrial customers. the 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 printer uses med wires, have different hallows,

which are said via wires. 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 and the lose the in the not is an impoverished form reminding count 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 that somebody use the objects that they're printers, produce, ship propellers, injection nozzles, such as in the chemical and food industries. and the pipes for gas has 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 the, the, the base place where we start to put anything on the top and then we will cut the thoughts or must be in your 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 like changing come a,

the approximate reflection of the wealth. and you 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 never 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. 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 particular voice of the army. thoughts thoughts like if in with this argument, fission design and one on the or uh, minimum of non business start going up now with the caught up in advance as documented the executive story there before the dc wasn't explored or, or what are the 2 successful business woman, 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 deal. and this is of mid markets, many keys the mid and i'm of show here. so obviously the long can see me,

i am in into the industry and these that are founded in seo fast, most package is the tool, but almost let's almost 4 months to minutes. they were minutes. so it took a make one so so but on do i have to admit of goddess manufacturing, the whole of cardboard boxes to be available? hope wisdom, us giving you will scale up anything. services stay will go showed us visiting cards, so sorry i was still under one roof angle. saudis and mrs. muniz the and i'm a w, i uploaded the phosphate the one on him. was it guy ma'am? you'll help him other than this. you need to last a good all big female business. talk you with the install august minute. the star key. i thought the subsidy, but almost the financing. got the what?

the whatever. um bank is bossy up ma'am. uh, which funding the financing give me when we get equipment mark mortgage will be you'll get her money hole up in the listed properties on naked. the other one on monday has been going on will be done by the fathers going on will be at the brothers will get i cannot be made it possible for all of us so many up now boys say he's got a game which he knew he thought he may be towards the star key, i thought the name, but to keep that i'll be gone. key x on the side of the neighbor gets all kind of machine picks. are they ok? the last few minutes sick. make a law how to to walk you through the game p for 10. does

he have any ation metal dealbreaker? someone presenting? told him what a little was for the key code of the oscar little mini possible thing guidance then it gives you the last few as they have them. thank you one, keep that of nikolai or pro 50. how may have was sort of on what made it bus 2540 time employees here. but again the money and we say hello 1040 keep an instability high for the installation, but we'll see what else again, business made up of 10 don't. so i did it in the family that adult betton. c, a hot angel, bulky sons that goes to in a i don't have money. no welcome mindset hit the little upset, oppressed with you guys. i think a lot easier to get you off of what the and how you at the teaching me that you have to dr. but a so you do proficient. so i'm giving you a tool to say if somebody i thank you one for simple. the woman not into

the business is to stick on that, so you can go on mental or bulky, that will build a woman is going to ask you to do 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 click on that to you the and i want to become one of the successful amino and this this woman alpha bucket 5 possible. thank you, this full on the 8th, the 15th of august on the, in the student where they go to do a quote female on in this be getting on the 5th. and i want to become a role model for the few. most of my agents not only nation anyone can to nationally met and to share this with electricity on

women and follow them and build a skilled development. vic, um could make any yes or a be good and could it be to get man for the programs they would have to feel it gave me for women and to find out to be so many within circle going to be female is the whole just school guidance because of all that's all just met of the industry level ending or just ethnic told us i'm business start them. no, i don't want them to commit singles up to people the and that's it for another edition is made the double use business magazine where we dug deep for the world's longest sanders, the tunnel checks out urban mining projects. and saw how 3 d printing could revolutionize the metal working industry. plus, we met a groundbreaking, women entrepreneur, chief thinking outside the box,

and we hope to see you next week. the
