jet 5 side, diluted and destroyed prophecy. europe today said just after a short break, our environment show kind of a looked at how to recycle an old u. s. military base. and there's plenty more using information on our website, dw, dot com, and you can follow some social media. for me, the team here to take care of the cream was like a stepping points, you know, 5 or 2 into that warranty wants to finish your studies. now you have a safety from the train, you can choose to go back or somewhere else, come and see more people than ever on the world wide in such a passion, life categories, something that is common very, very sense. and yeah, can we learn more about or know when a story info, migraines can you see is what cod tires have to do with you production? here's a hands on the

really indeed the snow on youtube. the. this 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 close for more than a decade. like many old bases around germany, we usually continue to rock or be torn down. instead, this many city is up for a makeover in this part of the massive urban experiments. 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 or of and minus

a construction trend that's picking up steam around the world. so how exactly does it work in tenant live up to the higher 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 u. s. army basis, 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, isn't it a circular city? is it a case of cause 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 chuck is hydro bigs deputy mer and heads up in the city planning department. some water shut seduce here. i can just see games, and these are sets of all the of that section. i'm going to do some a tie in. these annoying shop 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 deacons to of the buildings

the 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. either quit development of they may have gotten this route assessed by that as to what allowed me to. and this was one that comes with my not much improving how we built 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 account for about one 3rd of all 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 instead 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? are the hazardous substances, for instance, you can estimate of buildings construction materials based on its agent location and it's database hope 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 in the floors walls and ceilings and making a checklist of everything looked hanging around the former base to do it shows you

that over 52 percent of the building is actually concrete and around 5 percent of the 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 and all of these databases, the 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 with. and so how do we manage materials so they don't become waste, but we can use them again as a resource color been 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. 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, 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 urban mining isn't one size fits all in the way we tried to solve the problem

is not the same in different regions in different countries. boucher iran ego researches, the built environment and co leads to un sustainable buildings program in the global south, for example, there just aren't as many empty houses, office and shops as in 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 many 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 fun weekends and things that can be directly reused will need to be sold the,

or the title's in cushion on the. i'm also going to, if i say 3 feet, if you 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 like to buy to haven't been unlocked. if it's in that in session had 2nd thoughts on and the pro locks in the courage to some of the been to gotten of the title of the sort of them to 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 reused to some degree. but for the 230000 tons of concrete, it's a different story with an inventory and literally for all right and this, and that would combine that and the to liked some type of components. my tell you all knowing the tone to refute that some time. that's what the ball punch last and to the end of this looks like before she didn't for the items vegas, it's a good time for you to add from. i tell you, i, you know, that some feet of,

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 deconstruct what's already here. it's also about rethinking how we built. so 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 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. if we are going to be building um st. 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 knew all about. the listening really intense eve of person. um does this my tell you all of us who yeah me months um basically a pleasure to buy the bike up for this. uh, how about the leasing team? us definitely looking to push them to the t, but these are my tie ends, ends, which was on and so on. 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 also have to step in to help overcome what might be the biggest challenge cost. so when you look at version materials the day and made

a lot of c o 2 and they're very helpful for the environments, but they are often a lot cheaper than secondary materials because labor, it's quite expensive. now current system, incentivizing urban mining and making it cheaper will help drive change, but it will still take time projects like fido bags, patrick henry, village, redevelopment or a start. but also show just how much has to change to get with an a smith of those goals. the name is i think i wanna say guns fee to mention for me that for the and size of the guys them cutting them into movies. feed of out of anything that you can go off if we need to get westwood. and then even to this guys low, i'll buy it and this kinds of things and this, this open of overdraft though. 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
