it sounds like a name for a teddy bear on carlo. that's where finland is doing nuclear waste more safely, deep in the ground. the northern european country is leading the way when it comes to storing radioactive materials from nuclear power plants. the fins are using cutting edge technology to ensure the nuclear waste remains buried for hundreds of years. but is it safe enough to answer that in this edition of made dw business magazine. and here is also what we'll be looking at. the construction of the do of largest, the 3 d printer building. germany's biggest warehouse for returns, goods and artificial intelligence becomes the master bore of bondage and bellow. welcome to the shell. it's more than a quarter 1000000 tons of highly radioactive ways to sitting around across the world. in some places, it is leaking toxins into the environment, and no one knows what to do with it except for finland or other countries wait. the

northern european country is pioneering, a new way of storing nuclear waste. our reporter co dora traveled to on carlo finland to take a look at the wells only storage site for high level nuclear waste. it's matt. so we've arrived at minus 437 meters on the ground. we're inside the only final storage facility for spent nuclear fuel in the world. there's going to be basically no danger of within the next hundreds of thousands of years. this tunnel is defined, the ground is supposed to be the game changer for nuclear waste. there a quarter of a 1000000 tons of nuclear waste, just lying around across the globe. in some cases, leasing, talk sense into the environment. and nobody really knows exactly what to do with it yet, except for the fence. so how did they do it? and does this mean we've sold the nuclear waste problem once and for all when i 1st

had the, since we're building a nuclear waste deposit site, i thought it was going to be in the middle of nowhere like in the optic circle. so no, it's actually just a 3 hour call right away from housing in a municipality of almost 10000 people cold air. which also happens to be home to europe's largest nuclear reactive municipality actually bid to the site and was selected from full possible locations. construction started in 2004. right next to the pallet on. cell is quite straightforward, doesn't that. but it's actually really remarkable that this happens. because the final disposal facility of a spent nuclear fuel has to keep highly radioactive waste from leaking into the environment. for a couple of 100000 years. to put that into perspective, a couple of ice ages will have come and gone, invest 5 that needs decades of discussions, planning and careful selection of sites and the feet of engineering. other

countries with nuclear power plants have also been looking for their own permanent storage sites. but nobody has even started construction anywhere else without your pro or anti nuclear energy. this problem needs a solution fast or because the waste is piling up and sometimes inadequate interim storage sides worldwide, but not in finland. also decades of research and construction, the site called and carlo case, whole and finish is about to start operating in the next few years. the project is financed by the finish nuclear power companies, which are probably owned by the finish date. we're ready to go. the trip down takes almost a quarter of an hour. so we've arrived at minus 437 meters on the ground.

yeah, definitely feels like a cave all around us is crystalline bedrock, a mixture of granite and the rock cold making a tight. and that's the 1st key to why this place was chosen to store the nuclear waste the age of the wrong guess. almost 2000000000 years. it's a rather on fractured rather dry. you know, we don't have a lot of front water moments in here. i'm to your son is the head geologist at the company responsible for the facility. the whole struggle needs to be on. we're seeing a sense that there is no economic all the things that, that future generations for likes to be out from their own. but finding the right, the rock is just the 1st step because nuclear waste is unlike any other waste. they have 3 main types, low level, intermediate, and high level waste. low level waste is usually stuff that came into contact with

radioactive material, like protective equipment filters or medical waste. intermediate waste equipment used in nuclear plants or weapons production like pipes, so insulating material. it can stay radioactive for a couple of 100 years. the deacon terminated and disposed of in low level waste sites on the over ground up to 99 percent of all nuclear waste falls into that category. the one percent of high level radioactive waste is the most problematic one that consists mostly of spent nuclear fuel rods, but it also includes waste from nuclear weapons production. spend broad still contain lots of energy enough to emit heat and remain radioactive up to a 1000000 years, and that waste is sitting and cooling pools, or in dry caustics around the world. a total of over a quarter of a 1000000 metric tons says the international atomic energy agency that's as heavy as $26.00 eiffel towers. and some of it is leaking radioactive material.

the best solution for handling and safely is bearing deep on the ground and leaving it to the k for a couple of 100000 years until it isn't dangerous anymore. to prevent the radioactivity from the rods from leaking in the meantime, it needs to be in case properly. in finland, the spent fuel rods are sealed into 5 cent to meet the 2nd and around 5 meet the high corporate canisters. they have been transported on the ground with a hoist, pulls of drilled into the bedrock along very long tunnels. the canisters are then put into the holes as in this demo drilling. wow, that. so do you hear my echo? then the whole is filled up with band tonight play, which is also used as calculus to i can absorb ground water that might sleep in and corrode to the corporate kind of stuff. and finally, the tunnel is back filled with the same material and seals with

a 6 me to 6 concrete slab. as you can see here in this demonstration tunnel, those capsules or canisters are the most controversial part of the whole nuclear waste repository. the problem is, what happens if they've been denied laya, has defects, or is damage and ground water containing sulfide and hydrogen does reach the canister. research as have shown in multiple studies that copper could corrode, and the canisters could fail much faster. and the company in charge as calculated, possibly already in a time span of decades. research on this is ongoing and the topic is a highly debated in the scientific community. but the sounds of the finish nuclear safety authority and pals, eva, is that the uncertainty isn't so high that they would pose a significant risk. and they stress that the kind of stuff is just one protective layer of many condo is meant to house all the future ways to finland's existing

nuclear power plants. nor is it clear how future generations will be able to tell that radioactive waste is located here, or if it should be kept unlocked. but that's a question for another video. but even so, finland is way ahead of most nations. maybe because of a unique mentality one, the role in there might be with bab, correct? my big mindset, the fin finished people there as being a kind of a mutual consensus that we need to take care of the ways not to leave them to the future. it's in that race sense. there has been very little, almost ation from the society to europe's largest sweetie. printed building is going up in heidelberg, germany, and it doesn't require as many workers and resources as usual. in fact, the construction site is much quieter and more relax for everyone involved. a huge

tweedy printing machine does the bulk of the work. the technology could revolutionize the construction industry. as our reporter, equipment personnel is found out of this machine does the work of several construction workers paid ladies down the concrete in layers and can build 4 square meters of wall per hour. that's how your ups and lodgers, 3 d printing building is being constructed and industrial building without windows site manager. she can easy who from nigeria, who studies in germany is happy with the progress. but when you talk about so if you skip this like this, where you have this type of fan or fed ex or where you have it with the next step to an order. and you obviously clear. it's a special type of homework for this. then we might have more than 3 times fast i done called us and i did. there's enough concrete in this time low to last for 2

days. keep travels from the who's into the nozzle that runs along the track. the process isn't just faster, it also needs less material and review of workers and it's cleaner than unconventional construction sites on we need to build this the for the, the nice thing here is just the people one present that or press the princess one present. that's a present missing lesson on one person that just works at a mix. everything is good with the cost on the list to tennessee, which is basically what i do as construction site manager who is responsible for checking the concrete mixer. he also takes care of office work on a smartphone. it's a much more relaxed atmosphere than on other sites. at intervals, they attach anchors to support the double walls. his colleague monitors the 3 d printer on the computer screen. but how does the free printer know what to print?

so basically the process is that the, i guess that's designed to build, this was all i have 0, we impose without him. this is what is possible. it is what is not possible. then after the design, it gives us this step 5, is that the, the step 5, which is what i can send the outline design of the building. then when, when slices with his lives, i will was suddenly surprised. besides them then with slices. then we get the g quotes, then we send it to the printer and then we've got to print the p as a, a german company constructed the building with the b o, d 23 d printer made by the danish company, cobalt. the structure, some and ceilings are being poured conventionally and are supported until the concrete drives. it takes 6 months to build the building, 54 meters long, 11 meters wide,

and 9 meters high. the building doesn't require any windows because it will only house computer servers. the architect you on 5 months has designed the largest and highest 3 d printed building ever. it's made possible through the use of steel girders. a new development in 3 d printer construction up to this as a result of special attraction is an experiment with this construction method to you and find out exactly what you can create within the guidelines of some very simple architecture requirements. that's not possible with any other technology, and that's what drove us happens to the owner and developer is a real estate agent who wanted to build something new and innovative. on the landmark site, the price was high, so we needed to know that it would generate a profit to you. i'm here it is because i'm so we invested a total of $2500000.00 euros here, including the land in front. and i can't tell you what it would have cost if we had

built conventionally equipment because we switched to 3 d printing relatively quickly each time i just wanted to know, can i make it economically viable with 3 d printing figures this? and i did. i did pull team one best option because the site manager also has to do some work by hand, especially the places where the printer stops and starts. he might have to make small corrections, but he doesn't ever want to go back to conventional construction. i really don't think i would be moving back to the big convention article. so sideboards, i mean, nobody knows the future, but i didn't believe that the printer printed with go on grow higher. i done with this. uh, i think i would remain with the tray difference in building with 3 d printers is rapidly moving out of the experimental phase and into the commercial market. as for to get easy, g, i just 3 d printer have enough construction contracts for the next 2 years.

sometimes as a case of buyer's remorse or delivery going wrong online shopper is and always satisfied with what they get. so they send it back and all of that needs to be dumped somewhere in germany. a little bit goes to the return facility of mail order from auto. it is huge. it would help 15 football fields. so imagine what that looks like when stacked with we turned packages. our reporter done has spelled, was a germany's largest warehouse for returned goods. the washing machines, refrigerators and large pieces of furniture, a huge hall crammed full of them. sometimes $100.00 trucks come here each day to the hammers returns that are in the western german region of westphalia. they are big and heavy articles from the poto online shops. the customers didn't want to

keep a creative home. there were usually between $34000.00 seasons a day, or whether it's wood, electrical components, smart tvs, or washing machine, either go to the front of the most of its electronics that might have been damaged during the delivery time or the customer didn't like them after all, they don't think maybe it was the sound quality. they're just so many reasons. so, you know, got to see the pressure and they're going to get stuff. some customers order 5 bicycles or even sofas, but only keep one as often happens with clothing and accessories. luckily it doesn't happen often, but the logistics specialist here sometimes just have to shake their hands on one customer wanted a freezer. you're good. bought 4 of them by mistake. so 3 have to go back. that's just one example for large tvs. a customer might reject the delivery because they see this huge package coming out to them on the stairwell and can't believe how big the tv is, i think didn't think about the size one. ordering 5 guns force their thought, any returns regardless of the size or weight,

have to be unwrapped in ship for transport, damage dense, and scratches. has the product been used, or is it just like new? according to daniel, the pricing of most returns can be directly return to the sales department. he's there to check, returned refrigerators and ben. sometimes he and his colleagues experience some very unpleasant surprises. you have not heard. we also sometimes get heavily used equipment which is worn out for me inside the north end due to the transport of sometimes hasn't moved into the station on the inside, due to food residues less than somebody moisture then forms and the appliances come a total loss. i'm going to attempt to solve it died, so even for resale, there's simply no longer in perfect type jimmy condition. in this i find even i'm a find some, some items that can no longer be sold, make up a single digit percentage here. but every return comes and great expense in terms of money and also to the climate. that's exactly what happened to furnishing

specialist home 24th. that's why the online furniture retailer opened up show rooms and major cities, mike berlin, so that potential customers can try out the products before ordering. not only can they see the fabric cover, but they can also touch it. afterwards many customers change to the color or size they want, since i'm not sure they spend ones, and i know i always find it difficult when i'm sitting in my living room, looking at some furniture on the tv screens, boston my account revision, i would there be a picture in front of me, and i'd like to look into 3 dimensionally. i'm strong, it's very practical. when you can see the proportions, then you have a better idea of the product as well as the income. around 7 percent of all orders are returned. that's good, so slowly on goods with online clothes shopping for example, the number is well over 50 percent across the industry when it

comes to large pieces of furniture. the return costs are only part of the problem, but he knows the environmental aspect is very relevant. every return also leads to c o 2 emissions. of course, not only do we have to repack the product and we have to pick them up. apple, we have to move them into the warehouse. and these are all factors that we want to reduce. that wasn't going home. 24 also tries to reduce the return rate by offering accurate descriptions and meaningful pictures on the website. if there's high demand for a particular item, the company's own photo studio will take new or additional shots within a few hours. they also photograph items that are frequently returned due to the color or shape looking different from the website. the company's own workshop can also repair damage that occurred while shipping them. the products don't have to be thrown away repair man's extend von can says that that not only

reduces costs for the company, it also makes their ecological footprint. smaller is a $100.00. it might take an hour or 2, sometimes 5 minutes, much depending on what it is. in the cabinets, chairs, shelves, sofas, sideboards, or even all kinds of decorations they arrive here every day you come some or a big, broken, scratched, or something is broken off and, and if, for example, scratches or broken parts can be repaired perfectly, they are sent to use if you need them to, to the outlet for so called be great products next door. this way home 24 can tap into a completely new group of customers. and it hardly has to throw anything away anymore . so i'm fighting, it's mainly coupled. so let me being in together, the bang for your buck ratio is just too good to ignore things here around to around longer than a week and we have no extra storage that for the goods have to be sold immediately

. such as hell. back at the hermas return center, in westphalia, a washing machine is being dismantled. workshops like this one are now common. the aim is to reduce the number of returns, the inspectors check, the customer ratings, and the reasons for the return. they also analyze the costs of the defects, collect the appliances with dfcs, and then we invite the suppliers or do identify the problem with our colleagues. what faults did the customers find and how can we avoid them in the future so that there are no more returns for every 10th of a percentage point that the number of returns falls save money and reduces the burden on the environment. several 100 unnecessary truck trips announced germany are appointed every day a be a recipe developed with artificial intelligence. could that be the future for

germany's be a industry for name and base be a brand backs is experimenting with artificial intelligence to mock. it's 150 of anniversary it has use a i to make a new beer from start to finish. the recipe, the production process, and the design and marketing campaign, well old generated with artificial intelligence. so is this all just a marketing gimmick? or the future of the you're making a reporter, alexa miles wasn't planning to find out. and he's one of the very few people so far to try bex, autonomous so what does he make of it? very good. this time it wasn't master on videos, calling to develop the recipe. but the artificial intelligence tool chat, g b t said with information from the internet. that's what's on demand. and it's what you find online or recipes from amateur brewers used to be a professional brewery. we operate in a different league,

but we're always looking for ideas what amateur brewers are doing. and these ideas have, let us to play with other types of hops that we've never used before to go for it on the anger. that's so that's a 150 year old traditional brewery. suddenly at the mercy of a, i, the hundreds of thousands of bottles roll off the production line every day in all kinds of varieties. because beck's now belongs to a b in best. the world's largest brewing company, and they're keen to stay current. not only do the recipe come from chat g p t, but also the name autonomous and the design of the can. i think the green comes out really well. how i chose? no, we've never seen the power of technology in

a to do something that was very groundbreaking, us this and you can see. and that was to be ready, one for our consumer. so yes, design was done. leveraging the power of a i, we are very much overwhelmed by the impulse to for action of the consumers, angles of the public. and we had $119.00 newspaper articles being published throughout europe about 6 ton of us. and we reached 17000000 people within the 1st 2 weeks. another a i was less than throw a bean chat was asked by check new service. hi sir, to judge the not get released clear. my conclusion that so economist is a joke. it's, we're for people who don't have a clue about here and want to be told by a machine what to drink. it's beer for people who have lost all respect for the tradition and crap. the brewing. when you do something can do, it's always going to come under the debates. right. and i do think that being the

1st to really scale and work without special intelligence and brewing has created that debate, i think. but there are many trends in the food and drug industry and with a i being such a hot topic that it's maybe going to encourage those comments. but the thing that we get, so i'm coming back to is that it has real, can seem a reticence, like these platforms are at scale. real people still work for backs down. aren't you worried about your job at night? how do you know? because the recipes we find online are from hobby brewer's hobbies we have our own recipe. manual for brewing backs, ibex, 50 pages faults. and since we haven't published it online nor have our competitors . and so i'm not worried about my descendants and the line to not come kind of all fixed only to about 450 cans about china missed a competition winners. if there is thrilled with the result is entre as condos more a i b, or might be available in the future. i wish i could get

a taste of that beer, especially now as we are at the end of today's edition of made. thank you so much for watching and to join us again next time until then from me and the entire team here in berlin is good bye. take care. the
