box with one miss all guessing through as rainy as a senses. and striking the c s. lights on. and that is what we have time for. we will have more coverage of this rails on the side with the 7 collaborations throughout the day. time money comes mckinnon. thank you for watching the news. the, the the is it is simple is currently more peaceful than ever on the move world wide and such a big part of what i find out about baby story info, migraines. we might have

a tiny problem with sola, and this was a zone for these energy is not what started delivering clean energy in the 19 fifties and took off in the late 2000 is all ready for the dumpster work because the technology is trash. but because solar panels are built the last 22, so soon we could be looking at 27000000 tons of out of the solar waste. and only a tiny fraction gets recycled around a 2 percent of old panels. landfills big from one plastics end up in the environments to precious metals wouldn't just go to waste and 3 recycling save emissions. so i'm hand the front jobs to find a fix. and this has to do with baking and bathing. now we have the french company,

rosie found it in 2017. they are one of the pioneers. and so the recycling this is antoine. hello. he has been working here for the past 4 years. so what are the main pro steps in your recycling process? so the 1st step is to get suite of the cleaners. so we do it with a demo treatments. it's up to release processing attorneys that any municipality moves, and then we separate the metal. we make any consultation. and then you have the last step because that's what the, what they send something different metals and these methods, we want to separate them from each other. so we have the chemical treatment, small night chemical treatment that we do that this i choose the city calling from the see the and this way at the end of the all the materials inside to give you basically a solar panel is made of a few main ingredients that need to be separated during the restocking process. you've got tempered glass thermal plastic glue the cells with silicon silver and

copper, a plastic backseat and an aluminum frame that holds everything together. of course, the precise mix of components varies by manufacturer. why is it so hard to recycle these panels? so the good thing we still up and then said them made to last very long 20. so to use outside anyways, a condition they can last because of the cost function. this construction with this phone, glass seating, the problem was pulling, they're screwing everything together. it's very, what's are resistance. the problem is now we need to recycle them and we need to separate all these materials to put them back in the economy. and the old music is always pulling there. so the most settings, the 1st step is to separate the materials from the putting those. this is not a possibility to crush sheets because if you crush you to create small plastic goods, all glued together with these pulling or less than the plastic is literally everywhere . so even when you now remove this,

if you still complexes the cells, right, exactly, you have different types of floating. there's even more years, there's even more. oh wow, this is difficult. so. yeah. so the 1st step is to get rid of the plastics. the panel, let's get put into this big grey furnace, and because rosie is still in the pets and same process. everything today is pretty much top secret. the mazda mind behind this process is b, c, c, u, c, t o, and co founder of rosie. the panel of bake for between one and a half and 6 hours, turning the plastics inside into gas. what is really important when you look at this process because it depends on the temperature, how the panels of the 2nd one makes the difference. what's next to the funds and

what these our, our noise and protection id protection. ease, of course, is not this time the full size is customized optimized for the truth. most of you sold off on it. so we think that's we, uh, once we, uh we, we manage to do this to improve the genuine regulation of the oven, depending on the, on the, on the so smart that your watch. so the, the most used to contribute to the process. it's not, i know, but we have paid old. it's a combination of the 2. it's covered. meaning we use the energy from the load your to heat up the oven so we can save energy, please. the combination of the competing between the machines, equipment, the oven and the fatal with the combination of the to make small mexico efficient rosie sense has it, is gases and it goes to through a 5 stage filtering system. they say only c o 2 and water vapor are released in the end. but despite the c o 2, recycling steel saves emissions compared to mining fresh silicon. creating the base

silicon, some quotes cold and which ships release us between 8 to 12 tons of c o 2 pets. one of silicon, rosie says, very cycling process only produces 3 times a reduction of at least 5 tons of c o. 2 per ton of silicon, the company wouldn't let us show you the solar panels going into the furnace. but this is what the solar panels looked like off the beam, baked in the oven. this batch is about 20 kilos and represents the content of one solar panel. you can see the glass. you can see the silicon waivers which are like super thin. yeah. and you can just move. yeah. and then you've got the complement. now this mess goes into the next range of machines that take on the salting job. when you look at

a typical solar panel from the weight perspective, it's about 76 percent last 10 percent plus the 8 percent aluminum, 5 percent silicon, one percent copper and 0 point one percent suv are. and it's that really valuable silva, that's the main goal of this whole process. so 1st, we need to extract the copper and glass. but this whole process is, is the only way to recycle solar panels. other companies are trying it with mechanical recycling, for example, is less energy intensive. it costs less and you don't need to be able to come in afterwards. however, the recovery rates can be low. sounds like solar materials and gemini, i using hate like rosie at the start of that process. but no 10, a co boss in japan, there's either one wholesale parts of place and likes the name suggests a really health and softness is used to separate the glass from the rest. another german company is putting it very,

very simply hitting the solar panels with lightning. this bus them into several components which i'll then salt about. i don't think i can take a key of favorites right now. mario's in pits us has been researching photo takes the load in 20 years and is concerned about how to deal with all the plastics in solar panels by not exactly happy, for example, with a, from a process in which the polymers of incident are right. if i, because we would use those polymers to go into a space for which the, the elements are still there. now that being said, it is very hard currency to take upon them, or that's inside the solar panel. get it out of the solar panel and, and tweak it in the way that we can reuse it as a polymer. it's very energy intensive to do that. and it doesn't really compete both energetically or economically or ecologically with making a new column. so plastics are going to stay a pain to deal with. but what about the remaining materials off to the mechanical

soul taishan? now most of them is here is a separate input. we still need to get out the most valuable one that is still in this photo of, of how excel is connected to the silicon. it's the silver, the thousands of pieces are 1st of all take sales and these containers go through a set of $5.00 to $8.00 kemi co wet boss that are connected to each other. here the silicon episode of us separated from one another. it is these tiny, tiny silver lines that we are talking about here. then jump into solar panel is to make the electricity available for an entire year's oil storage in a battery. for example, in case you wondering, this is as much of the process as we could show you the can you specify a bit what kind of a chemical to use? because chemistry is like a really wide so we avoid the use of organic slogans. it's turned assets and we

have specific condition was different best to treat the diff, what's it will take? so that's as specific as they would get because we can't really show you the inside of the process. we set up a small experiment. so you 1st have a photo of a takes out as they enter and every step you can see the syllabus thing is detached the to more. it's like really tiny small fingers. yes, it is very, very soon. and elizabeth like hair. yes. once the purity on the silver and on the silicon. 3 comes out of this. so our process is in general, unable to keep this impurity for the material when they come in. so we do degrade the purity. and so for example, for the silver, it comes from silver paste on the, on the sales and silver paste or in general above 90 percent. sure. which for the suited cool. it's

a 99.9 to 9 percent. oh okay. that sounds quite sure. the recovered purity is in line with scientifically published papers, but for the economics of the process, another number is important. how much of the materials is actually covered with that combination of thermal and chemical recycling steps, rosie says they are able to recover a 99 percent of the glass aluminum and copper 90 percent of the silicon and 95 percent of the silver. which means that they get about 10 us dollars worth of silver out of each solar panel. the other stuff, glass aluminum copper and silicon is with another 10 bucks. but of course, the recovered materials costs more then version materials. do you have the feeling that companies are willing to pay these premiums that you have for recycled material? yeah, unfortunately, the don't say the premium. but today,

all the big companies, all the induced companies in europe have very strong targets on c o. 2 reduction and using recycling that they all use a very good way for them to reduce their c o 2 emission from their real materials. so already we city coding, for instance, the suits we missions of city can function is very high. so far of custom, there is crucial that they use let's see what we intend to use. my tails and our city con. confuse people to these targets. i would have loved to compare the price is we covered materials to actual market prices, but rosie wouldn't tell me the numbers. luckily for them and fonts that is a so called gauge fee that every solar and pull to also must pay to recycling companies to make sure the panels arrived fully taken care of at their end of life . just to put this in perspective, as study by the us national renewable energy lab, put the cost of trashing edge solar panel at on the $5.00. whereas recycling one

would cost $15.00 to $45.00. so how do you make recycling pay? rosie? say they can process around $3000.00 tons of solar panels per year here. not really that much compared to the millions of tons of trash expected in the upcoming years . and it's not even enough for them to break even. but they're already planning to build a facility 10 times bigger in germany by the end of 2025, which should be able to handle $30000.00 tons per year. however, up scaling such a process is a real challenge. as the c o told me what the very big scale recycling sites will have to organize it very well. the operate test engineers technician is to or the cheese ability system and also how to integrate the operate test. so human beings with the automation to reduce the cost to protect your maximum,

the safety of the, of the sites. also, you cannot use this recycled silicon straight way to form and repeating module. one of the reasons being the technology moved on 2030 years ago. silicon of 99.999 percent purity was use. sounds pretty pure. however, today silicon more than a 1000 times pura is required. so you need another purification process off to this to create new silicon ingots and new wafers to put in to new modules. this has been done on the science sides. for example, by germany's count who are for institute research buddy that works closely with industry pods. but rosie is taking a different route and it's selling it's recovered materials to the automotive building and electronics industries. if it is, or the video like it calling on it, sarah,

and don't forget to start our title. we've posted the videos on the environment every friday, but the over the past months, we've had all eyes on euclid protests in kenya, and seeing youth raising their voices across the continent. and today we wanted to meet some of these people and discuss the issues you're addressing. welcome to the 77 percent. i'm your host. ok to english not. so here's what we've got. first, an exclusive interview with k as president william until the pro fee. why act of us like keeping up the pressure on kenya's supplement.
