the that's it for now we'll be back soon with more headlines the meantime. you can find this online dw dot com. check it out on youtube as well under the dw news channel, obviously from beardsley invalid. thanks for watching the welcome to put tire time. that's kind of sofas. thanks tourism. what do you get here? you can't get anywhere else in the world. in germany, if you go to a prostitute twice or 3 times as much and the other half the service in 2023, a documentary, uncovered corruption on child abuse. the youngest one, for example, let me show you this was now the film team investigates the the was executive

has changed. the red light, dark shadow, 6 tourism the list goes to town in the german city of heidelberg, used to be a bustling us army base housing, nearly 5000 people but it's been closer more than a decade. like many old bases around germany with usually continued a rock or be torn down. instead, there's many cities up for a makeover in this part of a massive urban experiment. while many of the nearly $300.00 buildings here are set to be referred to as those that don't fit into the plans aren't just going to be demolished, they'll be picked apart and their materials will either be recycled or reduced. this technique is called urban on

a construction trend that's picking up steam around the world. so how exactly does it work in tenant live up to the high, the 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 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 are mining concepts within the circle of the city of that kind of stuff because i some stuff with this was mentioned, huntington, the less than that, i can be sweet. i mean, that's all the guy from voice you're getting a chunky is titled bags deputy mer and heads up. did city planning department some board and fed citizens here? i use the games and when do the shots of, or the of that section, i'm going to do some a tie in des moines for 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, 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. quite a lot to me that they haven't gotten this fault is asked by that as to quite a lot me to that it was my mouth and some comes with my mouth, much improving how we built things. it's 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 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 . but to use henry square extra e t a and 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? are the hazardous substances? for instance, you can estimate of buildings construction materials based on its agent location. and it stated this hopes that he's 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 and the floors walls and ceilings and making a checklist of everything. look hanging around the former base to tells you that

over 52 percent of the building is x, the concrete in the wrong 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 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. and mining is the systematic management of everything that's mandate. so before everything is coming to waste. and so how do we manage materials? so they don't become waste, but we can use them again as a resource. paula urban 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 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 go of, we're using what we 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 an office park out of old house, but it's similar been mining projects that popped up from switzerland to belgium. and cities in the us are increasingly building material databases and passing laws that require buildings to be deconstructed, not demolished. but irving mining isn't one size fits all. so the way we tried to

solve the problem is not the same in different regions in different countries. boucher iran ego research has the built environment and co leads to un sustainable buildings program. and the global self, 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 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 the real fun begins on the things that can be directly reused will need to be

sold. the or the title is in cushion on the i'm also going to, if i see that the, i'm a stick doors on to that and sure thing on bus picking on. i'm a to and i'm a to and come on for life divide. i haven't been unlocked if it's in that, in session that's taking dodge dental and the pro marks in the groups. the amount of they've been, they've gotten to the title of the sort of the, 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 degree. but for the 230000 tons of concrete, it's a different story. the tone literally for all right, and this and that would combine that and of it select some type as components my tell you all knowing the tone to refute that some time. that's what the punch last until then, the lessons that started before she didn't for the items to be a good. the ticket time for you to out from i tell you, i, you know, that some feed or 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 the architect this whole process to be more of a assembler. also 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. if we are going to be building, um, say office buildings and the build this out. can we design these buildings so that these buildings could be deconstructed easily? thing 20 or 30 years, or 40 years. 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 me. listen really intense eve of putting and that's, that's my tell you all of us who you me months um basically a pleasure to buy the bike up for this. uh, amenities and team us. definitely looking to push them to the t. but these are my tie ends which was on and so on. and with an individual or been 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. so when you look at,

in materials the day it meant a lot of c o 2 and they're very helpful for the environments. but they're often a lot cheaper than secondary materials because labor, it's quite expensive. now current system, incentivizing urban mining and making it cheaper, we'll help drive change, but it will still take time. projects like fido bags, patrick henry, village, redevelopment or a start, but also showed just how much has to change to get with an a smith of those goals. the name is i think shonda say guns for you to mention a funny that for the and size of the guys them come on the movies, feet of office, of anything that you can go off, you to put new posts them. so, and then even to this guy's low by this kinds of things, and this all kind of overdraft out. let us know in the comments if there are any urban mining projects happening where you live. thanks a lot for watching and don't forget to subscribe. we've got new videos for you every friday, the

kinds of crisis ice, hockey, 50, rotates and has a big 3. mean she wants to qualify for the national but there is less time for training because winters are getting shorter. despite that, how can she get closer to realizing her dream? she lives up next on d w. they want to make that dream of in house come through. the best way to do is stress new homes with plate or renovate old buildings and say resource. and there's nothing wrong with it because well that's of the house to fill sustainably. a construction revenue
