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 well be looking at. The construction of the do ups largest, the 3 d printer building, germanys biggest warehouse for returns, goods and Artificial Intelligence becomes the master bore. Im to bondage and bellow. Welcome to the show, a more than a quarter 1000000 tons of highly radioactive ways to sitting around across the world. In some places, it is leading 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. Its matt, so weve arrived at minus 437. 00 me cuz on the ground were inside the only final Storage Facility for spent nuclear fuel in the world. Theres 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, leaching 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 weve sold the Nuclear Waste problem once and for . When i 1st heard the since were 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, its 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 europes 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 font style is quite straightforward than that, but its actually really remarkable that this happens because of 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 anti nuclear energy. This problem needs a solution fast or because a waste is piling up and sometimes an adequate 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. Were ready to go. The trip down takes almost a quarter of an hour. So weve 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 thats the 1st key to why this place was chosen to store the Nuclear Waste vh up the wrong guess. Almost 2000000000 years. Its a rather on fractured rather dry. You know, we dont have a lot of front water moments in here. Im to your son is the head geologist at the Company Responsible for the facility. The whole struggle needs to be on worth a in 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. They are contaminated 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. Thats as heavy as 26 eiffel towers. And some of it is leaking radioactive materials. The best solution for handling it safely is burying a deep on the ground and leaving it to the k for a couple of 100000 years until it isnt 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 sent to meet the sick 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. So deep, you can hear my echo. Then the whole is filled up with bentonite play, which is also used as capital into i can absorb ground water that might sleep in and corrode at the corporate kind of stuff. And finally, the tunnel is back filled with the same material and sealed 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 the band tonight laya, has defects or is damage and ground water containing sulfide and hydrogen does reach the canister. Research as of shown in multiple studies that copper could corrode and the canisters could fail much faster then the company in charge has calculated possibly already in a time span of decades. Research on this is ongoing and the topic is highly debated in the scientific community. But the stance of the finished Nuclear Safety authority and pals, eva, is that the uncertainty isnt so high that it would pose a significant risk. And they stress that the canister is just one protective layer of many condo is meant to house all the future ways to finlands 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 thats the question for another video. But even so, finland is way ahead of most nations. Maybe because of a unique mentality. One, a role in there might be with bab, correct my big mindset, the fin finish people there as being a kind of a mutual consensus that we need to take care of the waste not to leave them to the future. Its in that race sense. There has been very little pulsation from the society. Europes largest, 3 d printing building is going up in heidelberg, germany, and it doesnt require as many workers and resources as usual. In fact, the construction site is much quieter and more relaxed for everyone involved. A huge tweedy printing machine does the bulk of the work the technology could revolutionize the construction industry. As our reporter kristen 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. Thats how your ups and lodgers, 3 d printing building is being constructed and industrial building without windows site manager. She can easy, well go from nigeria. We studied in germany, is happy with the progress but when youre talking about stuff, you skip that. Do this like this where you have this type of fan or fed conceptual way. You have it with the next step to an order, and you obviously clear its, its best that, that perform well for this. Then we, i might have more than 3 times fast. I done called us and i did. Theres enough concrete in this time low to last for 2 days. Keep travels from the whos into the nozzle that runs along the track. The process isnt just faster. It also needs less material and review of workers. And its cleaner than unconventional construction sites on we need to build this the for the building ive seen. Yeah. Is just the people one present that or press the princess one . Press one. Thats a present missing lesson on one person that just works at a mix. Everything is good, whats the cost on the list to send it to, which is basically what i do. As construction site manager, whos responsible for checking the concrete mixer. He also takes care of office work on a smartphone. Its 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 3 d printer know what to print . So basically the process is that the, i guess thats designed to build it with all i have zillow winters without them. This is what is possible. It is what is not possible. Then after the design, it gives us this set fires. That is the, the step 5, which is what i can send the outline design of the building. Then where, where the slides is with a slides that will was suddenly a set price for the slides and then with slices. Then we get the g quote. Then we send it to the printer and then weve 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, cement 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 doesnt require any windows because it will only house computer servers. The life of the architect, young folk month, has designed the largest and highest 3 d printed building ever. Its made possible through the use of steel girders. A new development in 3 d printer construction 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. Thats not possible with any other technology. And thats what drove us feeding. 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 unions because um, we invested a total of 2500000. 00 euros here, including the land. And i cant tell you what it would have cost if we had billed 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 because this and i did. I people came invest 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 doesnt ever want to go back to conventional construction. I really dont think i would be moving back to the convention, arkansas sideboards. I mean, nobody knows the future, but i didnt believe that the printer prints and wed go on grow higher. Ive done with this. Uh, i think i would remain with the tray to print and building with 3 d printers is rapidly moving out of the experimental phase and into the commercial market. As for to get easy t and just 3 d printer have enough Construction Contracts for the next 2 years. The or sometimes its a case of buyers remorse or delivery going wrong Online Shoppers 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 germanys 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 hair most returns that are in the western german region of westphalia. They are big and heavy articles from the pump, tow online shops. The customers didnt want to keep a creative home. They were usually between 34000. 00 seasons a day, or whether its wood, electrical components, smart tvs, or washing machine on the front of the most of its electronics that might have been damaged during the delivery time where the customer didnt like them. After all, they dont think maybe it was the sound quality. Theyre just so many reasons. So, you know, got to see the pressure and theyre going to get stuff. Some customers order 5 bicycles or even sofa, but only keep one as often happens with clothing and accessories. Luckily it doesnt happen often, but the logistics specialist here sometimes just have to shake their hands on one customer wanted a freezer. Youre good. Bought 4 of them by mistake. So 3 have to go back. Thats just one example for large tvs. A customer might reject the delivery because they see this huge package coming out to me on the stairwell and cant believe how big the tv is, i think didnt think about the size one. Ordering 5 guns force their thought. Any returns, regardless of the size or weight, have to be unwrapped and checked for transport, damage, dense, and scratches. Has the product been used for . Is that just like new . According to daniel, the pricing of most returns can be directly return to the sales department. Hes 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 hasnt moved into the station on the inside, due to food residues less than somebody moisture then forms and the appliances come a total loss. Im going to attempt to solve it died, so even for resale, theres simply no longer in perfect type jimmy condition. In this i find even im a fun to 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. Thats exactly what happened to furnishing specialist home 0. 24. 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 that they can also touch it afterwards, many customers change to the color or size they want to spend so much you, they spend ones and i know i always find it difficult when im sitting in my living room looking at some furniture on the tv screens boxed in my account revision, i would there need a picture in front of me and id like to look into 3 dimensionally. Im strong, its 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. Thats 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, but we have to move them into the warehouse. And these are all factors that we want to reduce. Now one thing, one home 24. 00 also tries to reduce the return rate by offering accurate descriptions and meaningful pictures on the website. If theres high demand for a particular item, the companys 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 companys own workshop can also repair damage that occurred while shipping them. The products dont have to be thrown away repair man, its extend. Vaughn can says that that not only reduces costs for the company, it also makes their ecological footprint smaller. Is a 100. 00. They might take an hour or 2, sometimes 5 minutes of all, depending on what it is in the cabinets, chairs, shelves, sofas, sideboards, or even all kinds of decorations. And they are right 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 im fighting, its 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. Thats in this house. Back at the hermas return center in west valia, 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 cons of the defects, collect the appliances with dfcs, and then we invite the suppliers or do identify the problem with our colleagues. What thoughts did the customers find and how can we avoid them in the future so that there are no more returns for 200. 00 . Every 10th of a percentage, points that the number of returns phones save money and reduces the burden on the environment. Several 100 unnecessary truck trips. Germany are appointed every day a be a recipe developed with
