exactly has changed the red lights, dark shadows, 6 tours and stuff all the 16 on dw, the, you've probably heard of bikes made out of woods and in the past, even cost for airplanes. what is a highly, versatile, durable, of cost, sustainable resource? one that's also used in a growing number of buildings. the problem is all forest and the supply of timber on the threads. thanks to climate change, model culture, plantations, and destructive pests. how about a natural solution? also coming up in the shows of some of the found that protects the environment and it's fish recycling comp. andres. tricky. and then you might think on

a young business woman who recovered from the phone out the big box of germany as far as this used to look like this. but now they look like this. in just a couple of years, this decades old forest has become unrecognizable. the same thing is happening in many parts of germany, europe and north america. but this isn't your typical the planet is dying story. this could actually be good news. but to understand why, let's back track a little bit some, or maybe more than a little bit to the end of world war 2. a lot of the world is in ruins and needs to be rebuilt. the allied forces, understandably, you want reparations from germany. but it's broke, so they agree that the country will pay partly in materials, for example, in bob,

lots of timber, according to some estimates equivalent to 10 percent of the countries for us. so now for us does need to replant big areas asap to rebuild germany itself. and which tree did they choose? mostly the spruce, which looking back was maybe not the best decision. but at that time, it seemed like a good idea to find out why we're driving to serena in the center of germany to meet funding for us to to fix this navy serious decisions and as fast growing regularly deliver century high quality one that can easily be processed at sawmills and of furniture flooring. it's used quite lively. as it is english, they have items and it's spa. that's why it's also a very lucrative treat german forest as planted vast areas with them in straight rows that make it easier to get in. and harvest spruce is of the most common tree

in germany and make up over a quarter of all forests. but that is changing rapidly because of what made this one of culture so profitable is also what made it so vulnerable. forest around the world, the suffering from more intense and frequent drought, wild fires, and storms weakening, entire ecosystems, and germany is no exception. the longest, some is due to climate change mean the forest to dry and the trees 1st, especially spruce street. they comparatively need a lot of water, but they root system is quite shallow. so they comp access reservoirs deep down. so while that's not the best news for the trees all for humans, there is one little creature that loves what's happening right now. into the box. this tiny little insect has been monitoring its way through many of germany's in europe. as far as the box. people of course, loves the box. it boils whole,

goes into the tree and then release its pheromones to draw a mate inside there they reproduce. emily eggs, a healthy tree usually produces resin to seal up the holes and to protect itself from the beatles. but sauce, the weak trees cannot. that's why the bulk beetle is having a se. i don't think john bodies vision likely years ago this area was holy forest. and dyslexia, if we're standing here now, and the last part of this area was infested in doing this here. that area could also be in the, in a matter of i as, as the beatles, each a way is that transport nutrients and water. the spruce is then die of fast and malnutrition. the beetle is good, at least spreading across europe and the halter. it gets, the more beetles will breed. what a full scale infestation looks like can be seen in bach beetle central, which is the hubs. national park in the middle of germany, where we're headed here about 90 percent of all spruce

is opted. the block people has come and gone, leaving behind the region. that is quite frankly shocking to look at. we're meeting the goal on peach, the head of the hots national park. the hot region is hit so hard because it had a very big concentration of spaces. but for peach and many others, this post apocalyptic looking scenario isn't the disaster, quite the opposite. for him, the bulk beetle isn't the villain. it's actually a blessing in disguise. the 5 years have a question is what's happening like, what's happening is that the old spruce trees are gone and the forest that belongs here is comic. when you see what kind of strength and how much life areas and it's beautiful, it's great and truly exciting. you push button, the pol, cut down a section of the forest as a safety barrier so that the beetle will have a hot a time spreading into neighboring forest. but apart from that, the national park decided to let nature be nature and did not find the box. and

nature is indeed doing its thing. different areas of the national park are treated differently. some parts squared trees are springing up on their own left to their own devices like this area that died off about 6 years ago. some parts need a little bit of help, meaning formerly native species that were displaced by this bruce, one of cultures a being planted. but that's just one part of the story. the national park is a protected area that cannot be used to produce tinder anymore, but only around 3 percent of all forest and germany is protected. the rest is governed by public or private forest, as, for example, to produce timber. and we'll probably be using more of it since would can be a very sustainable and renewable building. material managed and grown by forest as like back in so ring. yeah. they need to take a different approach to the bunk b to the trees are checked for interest ation regularly. once and interest stations

found latrice. i'm ok then that are top down and removed as soon as possible to hold the spread of the beetle. leaving behind vast areas of prematurely felled trees to prevent something like this from happening. again, the approach here is to not only bent on one tree, but on a variety of trees. by auction, it's like with a star or you're diversify your portfolio to minimize risk. that's what we're trying to do with the mix for as to why it, how this is an equal fish, be a scientist trying to identify the forest of the future. here are some of the candidates, 1st audio genes. beach ok, and sycamore trees are adapted to low elevations. they can survive with less water because they root systems are depo seconds of a new come out and select the douglas the native to north america. douglas fast can also handle more heat and droughts. these are currently seen as good candidates,

but if we continue to heat up the planet, we will need to mix in some wild cods to find out which ones may be suitable with the syringe and forestry has been conducting and now of a 10 year old experiment. in the driest region of the forest was, is open to so it's more or less because in a mixed for us to have to deal with various species of trees or supporting each have different risks and costs its price here all the way through to the marketing of the word or other product locked in for quotes with the home phone. but from our point of general, it's worth it because it reduces the rent and just go over it with you. you might have more expensive, smaller yield and budget for the forest owner. it carries less risk, the go, he's a quote hosted thoughts based explained by visits on this type of forestry, as well as the national parks approach shows where a lot of international forests could be heading. if you guys are also a chance to adapting life change or speed up by 4th version. yeah. which would

otherwise take much more time. it's best to get off of onto playing. does this, it's all good in terms of addressing the climate crisis, and it's good for resiliency as well as bio diversity. ok and see if i would, even though it might look tragic, a new batch of forest is already starting to grow. one that is more resilient than what we created before. and one that will hopefully weather and adapt to whatever is going to happen in the coming decades. some of them might not be the cheapest addition on the market, but it's a popular and relatively healthy option. and comes in a variety of phones. conventional some of the phones have come on to fly up and using feed containing soil and due to pa sites that cause painful diseases in the fish. and no way one fish farm has taken an alternative approach. the fjords of norway, a popular tourist destination and now home to

a new kind of salmon farm committee to doing things differently. the country supplies over half of global production to my smear hold is ceo of pack for the future, which operates the farm. whenever he can, he leaves his office to head out along the fjords to be with his team of labor, the trying to find a new way of in solving farming. and our goal is to reach the, the utopia of having the world's most sustainable sound with farming it's. and we live in the working pro actively to mitigate the problems before they become problems like c lice, for instance. so we don't have any c lie, sir, and also with passages and 1st i seem to face parasites are a major problem for conventional farms. the specially slice, tiny crustaceans that can even cause mass di of some of them there ost and they can also be transmitted to wild atlantic salmon whose stocks have plummeted by more

than 50 percent since the 1980s. environmental list. say it's a major problem. let's see donna's is a very bad thing for the sidewalk in their plans, but it's also it's a problem for the right side of them and the wind. so i'm in this area, is that the land think so i'm, i'm, and now it's tracking or, and the increase in numbers i've heard is there a month ago? another issue is that the fund fish often escaped through gaps in the nets. if they then meet with the wild atlantic, salmon, they are off spring struggle, just survive. leading to a further decline in the ocean, going population and excrement from the agriculture facility often pollutes the surrounding waters. that in turn promotes the spread of skin diseases and the fish . so what makes this 5 different? the key lies and its construction. instead of being surrounded by nets,

the fish pins are enveloped in plastic. or we have a, a protecting bowl like clothes and bag and up, the faces in. and we filled that bag with water from the, from the depth. so it's a fresh water from the depth without sea lies. the aquaculture pins are made of an impermeable plastic outer skin or bag and didn't to prevent the fond fish from escaping and endangering the wild atlantic salmon. that double barrier also keeps license other power sites out of the pin the pins, get a fresh supply of water piped in from the cold steps of the ocean. when there are no sea lies excrement from the fishes collected by a filter under each pen. and then pumped to the surface it's dried and then

used by bio gas plants to generate green electricity or by farmers as fertilizer. where the only 7 farm or that i know that don't time. so you lice and when the 2 steps to just drive inside of a good environment, 3 of have very good growth. so you have very low mortality, and very good quality of the fish that to harvest. in 2023, the average farm semen mortality rate across norway was 17 percent. with infectious diseases, i'm major factor q. the rate is just 4 percent. thanks to a very low level of disease transmission. the boss shows us the filter systems that are installed under the pens in the assembly hall pump units are being built, which will then be welded together. the company has a patent on the high tech filters. this is outlets,

so this actually regulates how everything is floating in the ocean and is also where we collect the floods. and if you have any dentist we think collected here it, take you to store and, and use it for uh, another value experience of a future size. it's making a profit and that it salmon is no more expensive than what sold by conventional producers. a re purposing the filtered sludge also helps in keeping costs down the for now, at least the semen industry is skeptical of the innovative young ceo will his approach bring a lasting, sustainable change to semen. farming to him, i smell holt is optimistic and is already hatching plans for an expansion. the

you see a lot more that 2 vehicles on the roads, roads these days, even though you can barely hid them. and while regular models create not just noise, but also app pollution tvs have no exhaust, although they don't totally green the heat. this the c o 2 from that production plus the environmental impact of battery minerals mining. so how about just recycling old batteries? this little part of good was once an electric. com. that's where you can, ford went through all that the and know you have all the good stuff, cobalt, nickel, manganese and lift him in here. and the idea is to turn these raw materials into a new venture where you get there are several ways, but this is one of them. first, the battery arrives at a recycling facility and gets discharged after it's taken upon the battery, then gets shredded. the liquid parts get expected and different methods of grinding

and sifting leafy with these base materials, metals from the battery, housing, plastic, and the bits of aluminum and copper bunk. the stuff that everybody is after is this black mass. this contains all the valuable materials, like lithium coal, both nickel and manganese, but also graphite. that's why it's black. and today we're going to get all of them out of there, but that's not my job. but there's, this is new, come to a doctor for research. i add to close todd and his chemical lab technician might, could come in at the university as part of a larger research group that is trying to figure out how to do this on a larger scale. and by the way, this is what the end goal of this process is supposed to look like. seen metal foil, ready to go into a battery again. so what are we doing now with the black box? so now we're going into the leasing operation with the blameless. so we are bringing all the valuable metals we have on the blackness into solution. the metal

way off today is called to bring that out. mike is using sulfuric acid as a solvent, pretty nasty stuff. if it would touch her, i was going, it would instantly costs a via buttons. we're using a process called hydro metallurgical recycling. it's a low temperature process, but only use a small amounts of energy compared to other vets where your 2nd method, this entire process is perfect for getting rid of impurities that are still in the black moss. after all, the shredding and sifting mainly aluminium and copper as a 2nd step, the black boss also gets filtered. lucas, as throughout the entire recycling process, they are able to remove 95 percent of impurities. on a scale, a little bit bigger. the whole process looks like this massive parts of solving in which black moss is processed. our black moss is now

edits to a nother solvent that will help bring out the cobalt in this chemical cocktail. and it's pretty colorful from greenish to doc blue. it's like so blue, it almost looks like ink it could like right, but that and it's this dark blue pod actually that the coal both sticks to to get a higher concentration of coal. both. we need to do another round of this. this time we're going from blue to red. now that's a color change or so now the cobalt is in the dock of red as pot spot to be able to use the metal in new batteries. you of course need to get it out of the solvent. you can do that by hitting it up as you would at, in the scale or a little quick kind of small up like this, with yet another solvent. really can see the crystals a lots here that even accumulates that the bottom like how much cold is that now

from the black mass isn't here, will actually leave of this, technically able to recover more than 99 percent of the cold. what are the biggest challenges in ops getting these process is what makes it so hot? you know, of course you, it, we also run the run through the problem that and let scale we are only doing dozen pets. explain. and so step by step, very common studies, but in industry you want to have the money. so you have that you're having a continuous process and handling a continuous process of, of all the impurities and all the process steps and small things you need to consider. it's kind of challenging. that's what other researches say as well recovering more than 90 percent of materials is possible. but this requires optimal conditions which you don't always find in the real world. if the recovery rates drop, the business case becomes even more difficult. when attended to you in the market is, is stressed to everybody minds who cycles by now the prices are quite new, which is a challenge for everybody who wants to go seeks investment basically is price is

a high recyclers make more money, but the question is, how much consulting firm mackenzie expects recyclers to make around $800.00 to $1600.00 per ton of battery. it's really about how much do you pay when you acquire the materials? this is hans eric mel and he's been analyzing the ends of lock. that's remarket for yes. so if you get material for free and then you process it, then sell it to market price, you able to use it and make a lot of money. you will most probably make more than many mining operations. but if we select those, what need to pay for the batteries? the economics can shake. this could mean recycling is more expensive than just mining new materials. and this isn't the only issue for commercial size ponds. another challenge, other materials used in the battery itself. it could be a whole bunch of combinations, lithium, ion phosphate, lithium, manganese oxide,

lithium, the cold, cold, many um, or lithium, the cold manganese cold. and the last one even comes in different compositions. 121-216-2222 or aids. $21.21. it's the wild west out there when it comes to bed 3 manufacturing, which makes it more difficult to build payload commercial off. the bottom line is and the real world recycling is much, much harder then on pay for another problem for recycling, batteries doesn't have anything to do with the recycling process itself. but with the missing feedstock, electric car batteries last longer than previously sold and off. so that they get used for all kinds of other things, like storing renewable energy, which means that does money batteries to be recycled on a left scale reciting. batteries is no issue at all. 9 to 9 percent cobalt because

it's insane. but on a commercial scale, not so much info that for example, well, it's only going to do with the home to buy products. so there's some questions that still needs to be on. so it never fell down and exhausted. you do work day after day. fun out is more common than many people think on can even affect the younger generation for res. hope. even if it's main starting from scratch, we met a young woman who managed to make it come back. it's been that even of advice, the best model, the things that increased as being able to make great money from a 6 hour work day left for me, but also having another leisure time to enjoy. like i said, i'm leaving home. she was 14. what you started

a business degree and 16 when she found it, her 1st company, when i got a loaner guy and i started my 2nd company and i was 18 and had to college degrees by the age of 20. but then the mission i had about enough time to come, but remarkably, she founded her 3rd company at age 22. mr. white, as the type of guy does this from being able to study and set up a company at that age was really liberating. is funds would not have the privilege of knowing early on what i wanted to do to move and i just couldn't wait to get started to keep them sports. i'm from wells her 1st company flopped. she was able to sell the 2nd edit decent profit and then developed an app for lifelong learning and in company training the semester to ensure the engine or shift for names, creating something out of nothing and solving problems for people in scale and off in seats and having that huge freedoms,

those creative lee and how i set my own life to the stipend, come and go back to us all these my name, also sure, a truly precocious challenge. and one who's already working on her doctor a while running her own company. being a highly challenging individual with a very high i q obviously helps when it comes to career advancement. but as with anyone else working too hard can lead to burn out syndrome. and i remember feeling to myself myself, that experience was the inspiration for a new business idea. providing mental health support for other entrepreneurs, like the june liable, a 3 month course costs $2.00 and a half 1000 bureaus. button visit a 22 year old, really in a position to provide coaching almost as long as i was just look at their track record and the fact that she'd already quit and so young an age expect to come. you

founding her 1st company when she was 16 is way ahead of main fema is and of course because the services are available online. the one of those with, with coach in the mines, normally coaching is one. i'm one of you to team, but there are a range of issues with group approach works really well. it is on that journey. so i'm glad taking time out is crucial, but she doesn't feel like networking is really work. this one is and so this is this, it's great just knowing i belong to by the yahoo, that i've been able to establish myself and be part of this. it goes to the one with what is the requisite loaner cars. he knows she's benefited from a lot of luck over the years, she has supportive parents and investors interested in her work, and she's always open to reinventing ourselves.
