cardboard boxes, then you might really enjoy this week. so except here everything's much bigger and way more exciting realty. 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 finished parts of a record breaking project, the world's longest pre fabricated tongue define. 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 floating drudgery in the world is also being used here. welcome to europe's and mega project. with mega challenge is still to be overcome. a critical moment during construction, the portion of the concrete, the concrete will be poured non stop for 30 hours. that will mean tens of thousands of tons for one segment alone inside the him. the key is to pour each elements in a single for you. 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 the we concrete, the entire segments and one poor 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 sooner totally here you could, this van,

the things went smoothly with the 1st pre fabricated elements. each is 217 meters long and 42 meters wide to name store and a 10 bits big recognition for the many hours that have been put in to get here from the business side to our designers and some of the construction organization at one time and the whole framework that surrounds the old noun, i bought the vehicle, i'd be pass opponents. who on the tunnel will consist of a total of $89.00 pre fabricated components with 2 tubes for trains and 2 for cars . the major 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 rios, 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 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 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 pay off the estimated construction costs are $7000000000.00. yours was the number one of one of 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. for

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 of i'm. so there is a safety buffer, it's really not a problem for you when it's done, husband on the sample, the in 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 bases, 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. so the city has

grand plans to re develop 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 of taste on the idea of a circular city where we treat everything left behind here as though it's 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 board and fair really are lots of resources here. and we want to value these materials and use them to build the new district and go into that 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 everything 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. all those will be tough. so all of this represents a new approach to old buildings and goods. improving how we build things. it's vital construction accounts for 13 percent of global energy related carbon emissions. and it's not just about putting up buildings, buildings, or demolish. they usually end up in landfill. all told construction and demolition account for about one 3rd of all 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 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 the 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? are the hazardous substances, for instance, you can estimate of buildings construction materials based on its age and location, and its database hopes that easily 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 and 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 has 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 tons 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. colors and 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 consumption became more common and we kind of let goals for using what be already have metabolic urban mining assets 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 offering formal sacraments, for instance, they are very sick, 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 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 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 really use 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 richard, 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 and this is some of it will be used as the base our streets of those are some of the different utilization that we've developed, big and we've had to do that for every single material. yeah, you know, that's an feed 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 simpler of materials instead of a designer of the 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 a waste. then it becomes a whole big thing. and the 2nd thing that happens on these specific companies are allowed to handle, that they are in the middle to log into all and with an individual or a big binding project, starting the 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. a

3 d printers are now being used to construct the 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 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, and 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 in the face 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 d printers to industrial customers. that costs per machine around $200000.00 bureaus. there are different versions like this come fact printer

for this one with a robotic arms which can produce very complicated shapes. many companies today, lack of specialists 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 middle wire is of different calories, which are set by a wire speeds. however, printers are not getting able 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 not is 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 nozzles, 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 or 2 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 a month it can take is on system then within

a design unless you need 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 screen in house. and 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 tickets. why? so the army. ringback thoughts hot next to begin with this argument of fish and design and one on the or uh, minimum of non business stock on that 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 woman, the money thaddeus, the 1st muslim business woman had and that will fit session with the key idea of when the case or the branding or practicing the face of man markets many keys made and i'm of show here. so obviously the loan could be moved. uh i am in entropy, the industry and these that are founded into your thoughts most package is the tool. but how much that's almost 4 months. said that if they were minnesota can make one still. so, but on the payment of goddess manufacturing,

the little cardboard boxes to be available, whole customer skinny, it will scale up anything, services, stable brochures, visiting cards, so sorry i was so sub under one roof on go study services. me that the the and i'm a w, i uploaded the phosphate the one on him with a guy, ma'am. you have the motor, the industry, you need to last that video, all big email business. talk you with the install august minute. just stark. me. i thought the substitute, but almost the finance got the what? the word of home bank is policy up ma'am. uh which funding your financing gives you the wanna get equipment more mortgage will be you'll get somebody hold up in real estate properties on the got the, the money has been going on will be the money father's going on will be at the brothers will get like a normal vs made it possible for all of us. so many up now going to say he's got to

get machine that eats or do you need the towards starkey i thought the label to get that will be gone. kia x on the side of the day, but it gets all tired of machine break. are they? ok? so was a minute. 6 nickel, how to walk you through the game? p, a force and dizzy, a 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, what sort of a, what? maybe plus $2540.00 time employees here. but again,

you'll have my invoice, get her last name, political instability, hypo 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 do that and see a ha, my angel lucky son that goes to and a i don't have money. no woke up mindset hit the will of set of breath when he care that they can not easily get you off of what the and how you at the teaching that you have to dr. but a so you do proficient. so i'm going to get you on save some, just thank you. one for simple. the woman not into the business is to stick on the 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 was to become one of the successful amino and business women of a focus on the box. most likely, just, well, i'll get it focused, it's all focused on to and the student where they, that's out to a female on in this be getting on the 5th. and i want to be the model, the model for the see most of my agents not only nationally but again to nationally met. and it showed this to the audio woman empowerment field. the skill level elements become couldn't make any use or i'll be good and could be to get man for the programs. they would love to buick at me for woman and to been out there will be say maybe within circle going be female is the whole just go by this isn't what i told just met up the industry level ending or the step next to it as

a business start to know what i do for the lead them to commit. they will have took you the that's it for another edition is made 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 on for bernard cheese thinking outside the box. and we hope to see you next week the to the points. strong opinions, clear position, international perspective,

the politics gone, brutal shooting against donald trump is just the latest example of rising political violence while motors in the us and europe are also choosing the extremes on the bowers onto the point we ask from insults to murder and you brutality and to the point next on d. w. equal method clowes, store and almost unlimited supply of water. but what to do when they won't release the pressure is liquid on their own pattern of dwindling rainfall is driving scientific innovation, turning vapor into drinking water, catching farm in response to draft the in 2 hours on the w, the

someone else's cd highlighted selected for you you every week, a new a box, subscribe. now what i know by i might just do it and i'm hosting dw, and you've called costs. thanks. trace amount because it's actually a file now. join us as we travel around your at tracy. this is a history of every day. ok. and that's something right around the well of course we're taking the juicy of stories with a little mystery of drama along the way. but no need to talk about, i just hit subscribe already. listen to process and will take you along to the

right side. the politics gone. brutal. the shooting against donald trump is another highlight of the trends towards political violence in the us and europe. the pictures of the blood stains, donald trump have already become iconic for his supporters. violence is driving radicals to what they consider the last resort to silence politicians just like here in europe with the attempted assassination of so back us prime minister roberts feet. so how do we get their elections like the ones in france also show a shift towards the extremes to the left and to the right. the center is losing ground onto the point we ask from insults to.
