demetrius on you to see the world the subscribe. now, to dw documentary 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 our forest and the supply of timber on the threats. 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 following, that protects the environment and it's fish recycling comp. i'd race of tricky. and

then you might think on a young business woman who recovered from the phone out the big parts 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, or maybe more than a little bit to the end of a world war to 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 angry is that the country will pay partly in materials,

for example, $10.00. 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 do fish. this navy is displayed and as fast growing. got it regularly deliver century high quality one that can easily be processed at sawmills and of furniture flooring. it's used quite lively as the english stay of items and that 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 reservoir, people down. while that's not the best news for the trees all for humans, and 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 be though, of course,

loves the box. it boils holes into the tree and then release his 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 beetles. but says the weak trees cannot. that's why the bulk beetle is having a feast from john bodies vision like 4 years ago. this area was holy forest and decisive. we're standing here now wednesday, last part of this area was infested and doing this here. that area could also be in the, in a matter of fine, but the beatles either way is transport nutrients and water. this bruce is then die of fast and malnutrition. the beetle is steadily spreading across europe and the halter it gets, the more beetles will read. what a full scale infestation looks like can be seen in bach beetle central, which is the hot national park in the middle of germany, where we're headed here about 90 percent of all spruce

is opted the box. 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 a disaster. quite the opposite. for him, the bulk beetle isn't the villain. it's actually a blessing in disguise. if obviously the question is what's happening later, but 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 there is, and it's beautiful, it's great and truly exciting year rush. but the pol cut down a section of the forest as a safety barrier so that the beetle will have a heart of time spreading into neighbor ring far as necessary. but apart from that,

the national park decided to let nature be nature and did not fight the box. and nature is indeed doing its thing. different areas of the national park are treated differently. some parts where 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 person on a 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 wood can be a very sustainable and renewable building materials managed and grown by forest as like back in so ring. yeah. they need to take a different approach to the bulk b to the trees or checked for interest ation. regularly. once in anticipations,

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 bet on one tree, but on a variety of trees. by auction, it's like with a sophomore, you're diversifying your portfolio to minimize risk. that's what we're trying to do with the mix for us to buy it. oh, this is an equal fish to 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 as like the douglas, the native to north america. douglas for us 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 to serena and forestry has been conducting and now of a 10 year old experiment in the driest region of the forest, as is often design, it's more or less because in a mixed for us to have to deal with various species of trees or people 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 view, it's worth it to 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 corporate hosted thoughts and he's playing vice visits on this type of forestry, as well as the national parks approach shows where a lot of international forests could be heading. this guy's, i'll also a chance to adapting my change or speed up on the 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. someone might not be the cheapest to push on the market, but it's a popular and relatively healthy option and comes in a variety of bones conventional. some of the phones have come on to fly up and using feed containing solely and due to pa, science that post painful diseases in the fish. and no way one fish farm has taken an alternative approach. the fjords of norway of

popular tourist destination and now home to a new kind of salmon farm committed 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 simon 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 see lice, 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. this is a very bad thing for the sidewalk in their times, 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, right. 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 wildlife to examine their op spring struggle, just survive, leading to a further decline in the ocean, going population and excrement from the aquaculture facility often polluted 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. and, and we filmed that bag with water from the, from the deck. so it's a fresh water from the depth. without sea lies. the aquaculture pins are made open, impermeable plastic outer skin or bag and to prevent the fond fish from escaping. and indeed, during the wild atlantic salmon that double barrier also keeps license other power sites out of the pin. the pin scared a fresh supply of water piped in from the cold steps of the ocean. when there are no sea lice. 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 southern farm or that i know that don't time. so you lice, and when the fish gets through just drive inside of a good environment. 3 of have very good growth. 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 close in the ocean and is also where we collect the floods. and if you have any database we think collected here it take you to store and, and use it for a another value experience of the future. so 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 hear them. and while regular models create not just noise, but also air pollution, tvs have no exhaust, although they don't totally green the heat. that's 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 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 liquid pods, get expected and different methods of grinding and sifting leafy with these base materials. metals from the battery, housing, plastic and a bit of aluminum. and copper, but 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 them. but that's what my job, but there's this is new come to a doctor or research a 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 in 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 have reading all developing levels we have on the blackness into solutions. the metal way off today is cold. to bring that out. mike is using so far it as a, as a solvent. pretty nasty stuff. if it would touch 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 batch where you're citing methods. this entire process is perfect for getting rid of impurities that are still in the black moss. after all, the shredding and sifting mainly aluminum and copper as a 2nd step, the black box 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 pulse of solving in which black moss is process or our black mazda is now

edits to a nother solvents that will help bring out the cobalt in this chemical cocktail. and it's pretty colorful from greenish to doc blue and like so blue, it almost looks like ink it could like right with 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 the color change. so now the color is in the dock a reddish box, but 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 as industry scale or a little quick kind of small left 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 bite mass isn't here? well, actually of, of this technique we are able to recover more than 99 percent of the cold. one of the biggest challenges in ops getting these process is what makes it so hot. you know, of course you, we also run the run through the problem that on that scale, we are only doing this and best explain them. so step by step, very common studies, but in industry you want to and money. so you do have that, you're having a continuous process and handling a continuous process of evolved impurities and all the process steps and small things you need to consider. it's kind of challenging. that's what other research as 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, this is the stress to everybody minds who cycles by now the prices are quite new,

which is a challenge for everybody who wants to go seeks investment. a 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 homes, eric melanie. he's been analyzing the end of last that 3 market 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 the site does 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 mangan, these cold. and the last one even comes in different compositions. 121-216-2222 or aids 21 and 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 in 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 thought 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 or on

a large scale recycling 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 a home to buy products. so there's some questions that still needs to be answered. never fell down and exhausted. you do work day after day. burn out is more common than many people think on can even affect the younger generation 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 my stuff with the some of 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 life. in spite of them, the mom,

she was 14, what you started a business degree and 16 when she found it, her 1st company, when i got i'm no, no gods. i and i started my 2nd company, and i was 18 and had to college degrees by the age of 20. but then i had about enough time to come, but remarkably, she founded her 3rd company at age 22 to mr. white as the type of scientists 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. and i just couldn't wait to get started to kids that i'm supposed to. 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 all

the entities and having that huge freedoms, those creative lee and how i set my own life to the stipend, come, i'm another for to us all these my name also sure. a truly precocious challenge and one who's already working on her doctor. and 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, the myself, that experience was the inspiration for a new business idea. providing mental health support for other entrepreneurs, like the june labels a 3 month course costs $2.00 and a half 1000 bureaus. but is a 22 year old really in a position to provide coaching almost engine i was,

i was just look at their track record and the fact that she darted quit so young an age except among you founding her 1st company when she was 16 is way ahead of main female and of course because the services are available online the, when it was with the coach in the mines, normally coaching is one on one of the 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 which one is and so this is the say, 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 because 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 yourself.
