to get there housing from there in baby shudders august 3rd 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. 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 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 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 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 the inside 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 during the floor. so that'll 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 a 2 by my and 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. it's an 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 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 real travel between northern and southern europe. faster and air travel redundant. the 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 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 on the tunnel from 2030 onward and 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 to sooner 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 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 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 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 with a mind. i can be sweet in a minute and basketball, the guy from voice you're getting a chuck is hydro bags deputy mer and heads up in the city planning department.

border 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. while 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 cell phone. 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 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 hyderabad 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 helps. so these like titled, may i get a sense of reusable and recyclable materials at their disposal when 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 look 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. 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 shell and focuses on the built environment at dutch sustainability, consult and see metabolic during the most trivial solution. i think that's what we see with a lot of production processes. that production became cheaper, must consumption, 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 no 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 sun, weekends and the 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, where 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 at 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 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 an 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 knew all about the listening roots. we have to be incredibly careful that none of the materials we collect here are technically considered 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 the song and so on. and with an individual or a 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 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 building all kinds of different plastic parts are already being printed and even exact copies of sharks and can be made to the 3rd tropi 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 part 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. bare 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 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 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 have your printing from it, it's up here. so far they have sold over $303.00 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. the laser printers use this metal wire is of different calories, which are set by a wire speeds. however, printers are not get table 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, in the, not as 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 as 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 the 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 design, and that was able to be manufactured into a component. so with our robotic integration system, then with the need to sign 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 all possible reflection 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

of the plus will stations are just that i'll 100. let's take a slice of the army, salt salt lake in with this argument of fish and design and one on the or minimum of non business stock than that now with the caught up in advance of stock in the other. that's the thing that gets deleted before the the she wasn't explored or, or what are the 2 successful business woman, the money that is the 1st well most name, business woman. and that will fit taishan with the key idea of when the case or the branding or packaging. this is of mid market, many keys the mid

and i'm of show her a so obviously belong conceivable. i am in into the industry and these that are found in seo fast, most packages the to but how much that's almost 4 months to minutes they were minnesota can make one so, so, but on don't have them at a cost us manufacturing the whole 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 sub under one roof angle. saudi services. me like the sonoma dykes applied to the phosphate. the one on him was the guy, ma'am. you'll have the model, the industry need to last a good deal, all big email business, talk you with the install. okay. minute,

good star key. i thought the substitute, but almost the financing got the what? the, what the bank is policy up ma'am. of which funding or financing any of the want to get equipment more, more visual be you'll get her money hole up in the end estate properties on naked the other one on monday has been going on will be the money fathers going on will be at the brothers will get, i cannot be made it possible for all what all so many up now go say he's got a game which he knew the tory need. he took the star key. i thought the label to keep that i'd be gone key. it's all those sided up and then be able to guess all kind of machine for saturday. ok. the last few minutes technical law. how to walk you through the game. p 410. gives you a video,

simple dealbreaker. someone presenting, told them what their logos for the cure code. c d. a v. oscar low, medium, also thing, guidance then it gives me the last few as they have a thank you. when you set up nikolai or pro 50, how many of was sort of on what made it bus 2540 time employees have like again bill money and we say hello 1040 keep an instability high for installations, but we'll see what else again, business men of up 10 don't. so i did it in the yeah. why didn't i feel better feel hot, angel, bulky son because in a i don't have money. no look on mindset. hit the little upset. impressed with you guys. that's a lot easier to get you off of what the and how you have to be to me that you have to dr. but a so you do proficient. so i'm giving you

a tool to save some of this. thank you. one for a simple, the women not into the business is the stick arms, and that's a environmental or bulky that will build a woman's going ask you to do an e commerce site or walk you to a business is it just may how much you already hold up in handicraft, so guess, well there's a heart care industry insight. they'd be on clicking on that to you the and i want to become one of the successful amino and this, this woman alpha focused on the box most likely just full. i'll get it. so 50, it's all focused on the industry and where the exhibits out to a female on in this be getting on the 5th. and i want to become a role model for the see. most of my agents not only nationally went into nationally met and to share this with. and that's how i deal with

women and follow them and feel the skill development they come. can make any use or a be good and can be to get man for the programs. they will have to buick at me for women and children out there will be so many within circle going to be female is the whole just school guidance because it will that's all just met of an industry and a binding or just ethnic told that some business start them? no, i don't provide them to the method was of took you the and that's it for another edition. it's made the double use business magazine where we dug deep for the world's longest under z tunnel checks out urban mining projects . and saw how 3 d printing could revolutionize the middle working industry. plus we

met a groundbreaking woman entrepreneur, p thinking outside the box. and we help to see you next week, the

6. so with jim sebastian, few countries of what's the war and ukraine more closely than poland, which was the time. and again, the poor thing would much be on his board is no one listing my guess this week, and more so just to just pick some of this stuff out of them, but not to put warnings because the government has to use the same conflict in 30 minutes. d w. age tells nice story to people who planned

dedicated to me. i am not too dumb to tell me. all the secrets of my the the down to 75 minutes on d w the this shadows. these costs and video shed lights on the dog is devastating. colonial har is infected by germany across and he employed the scorched coast, tactic farms and destroyed lights. what is the legacy of this wide spread races, depression, today? history. we need to talk about here, the stories, shadows of german colonialism. this video changed the world. it

shows us soldiers killing civilians in the rock more often posting. it's julia songs became a wanted man. 14 years later, we can make found it is fine, is history general is done during the traces, the stories of a soldier under the volunteer of the attack. they speak to each other for the 1st time in your heart to forgive me. but that the follies don't think that i carry any resentment or a grudge in my heart towards a captivating story about this struggle for forgiveness and truth guardians of trees. julian, his sons, and the dog, secrets of war, starts july 27 on d, w. the

the this is dw news, life cumberland, us president joe biden cancelled a campaign event after testing positive for coven comes after the most prominent congressional democrats tells by them to quit his bid for a 2nd term. representative adam shift says he has serious doubts by it and can be trump in november's election. also coming up, germany cuts the military aid for ukraine by nearly a half. the government announces spending plans for 2025, but the defense spending increases slightly as germany aims to reach its native targets.
