in the house. i'm tired of 34 years. i was a metal. i didn't know what has the best. now i know the never ending story of asbestos starts june 21st on d w. the plastic comes with all shapes and colors. it can be hard or soft clue like gloves get unbreakable or it can be a nice day. plastic is cheap to produce and it solves lots of everyday problems. boss is also creating a problem. we're producing more and more of something that isn't biodegradable.

instead of decomposing, it breaks down into small micro policy calls so small that eventually they can no longer be seen with the naked eye. plastic particles of floating and now at oceans and accumulating. and also that means they also end up in our bodies. micro plastics have even been found in human plot. how can we get micro plastics out of the environment? how can spiders help? and how options coping with micro plastics? stay with us for answers to these and other questions. hello and welcome to tomorrow. today to science show on dw the each year a person may consume up to $90000.00 micro pasco plastic by a drinking boat. the know most of the treatment plans are you able to filter micro

plastics asked the voice. but a new process is taking advantage of a special characteristic of micro plastics. they tend to stick to air bubbles. monday 9 am. net portable in germany is that it's not just my dream that it will be a dream for everyone. they might just be a little bubbles, but they're going to change the world to the engineer roland diamond is researching a way to remove mike cray plastics from the water tested. cuz i know how close the deform micro plastics are assignment killer. yeah. since we started producing plastic on this planet, and so within around 70 years, we've produced 9200000000 tons. it's equivalent in weight to about 178000 titanic's the 2000 by the tonic. a large part of it can be found in lum, felt was disposed of callously in the environment. eventually it turns into my cri,

plastic various different types of ult, official materials end up in the wells full test. like tie of particles, credit units, and mike craig fight, that's the i. these are stuff as an investor off, all of these substances are present in the water. i'm 40, it didn't call it. you have to lean is particularly nasty, often in well, it absorbs toxins, then fish heated, and those toxins end up on our dinner plate. you think bones that's not very advertising now, particularly here. flushed every day we can see mike cray, plastics and the feet. we talk about 6 grams a week on average. it's the amount needed to make a credit card. research a suspect, the correlation between caustic particles and novelty and such an illness says like i've called you a box given disease. to roland diamond has

developed an ingenious yet simple method for removing these particles from level to use as tiny apples. notice my crate bubbles gets easier, but we extract the water here which we then put into our pressure saturated. this is where we add the compressed air and we mix everything with the water under pressure and bossa on the spot. so water and then passes through the pressure line to the release spouse and this. and then you can see how we separate the micro plastic system equal plastic. we add the micro bubbles which pull them to the surface. it's an exciting effect. and the best way to respond to to illustrate this stuff on, i'm just calling to highly concentrated mike cray plastic full to into the test base. and all turned on the entire sucked in, mixed under pressure and forced back into the base and 3 mike crude, find phones. levels are created with a diameter of up to 50 my chrome. it says about one 3rd of a human have the micro bubbles, a truck,

the plastic particles and transport them to the will to surface this works because micro plastics. a hydrophobic little hydro though big means micro, plastic, so water repellent. they don't like water when we introduced the micro bubbles into the water. the plastics are almost magnetically attracted to the bubbles, smoking the. they immediately latch around to the bubbles, outer shell, or any blossoms. they then rise to the surface on the micro bubbles and we remove them from the water. and also with this a simplified look at what's happening. the bowl symbolizes the micro bubble. and the sticky paper is the micro plastic. when the bubbles have the plastic, they stick to the bubbles due to the force about asian, the know and see the micro plas 6 that we hope to the surface is from

a large scale plan. we'd remove that with an appropriately engineered system to make sure it doesn't make its way back into the water. is your stand down on stream is to build a large scale pump. one, the computer, a fi, several heck to as of what the surface power at the depth of up to 20 meters, the palm would be my bile until i clicked on a slate. the switching part would consist of 2 components. one would be under voltage whether micro levels are produced by valves. the 2nd toss lights above it and captures the micro caustics for the 1st time dumb on his team at testing if it really works. and that's what's in this into it. if i suppose, if this works, i might jump for joy into the lake. it's always bad luck to anticipate good results

like that. but of course it would be an impressive milestone for our project if it works today for you. with us, the demo on his team has been waiting for the stay for road for a year and a half bought in to stop the engine. the parts are tied is controlled from the show just like the model and the power tray arrant was for a pressurized and the compressor. and the mixture is fet street hayes as to the floating ring and this approach bounds to my critical shift then rise to the surface. typical this is canada effecting this is exactly the effect we want a lot. we have a small defined bubble pattern. you can see the micro bubbles forming in the water . it's an incredible effect on is i can put it into words. i'm not often speechless, but i'm a bit at the moment. it's the foundation has been laid now. roland,

man, on his team, come back in the next phase, will take the system into a flowing body of water. just see how it behaves in that environment. it's an indescribably happy moment. by 2026, the experiments should be completed. and the micro bubble floating system should be ready for market chosing made of synthetic. microsoft is a soft, doable, and can retain a loss of moisture. that's why it's a popular choice for sports. but each time it's washed micro plastic particles end up in the environment. plus synthetic textiles on not biodegradable, so all the,

any better alternatives. what about the threads made by these tiny little spinning mazda is a, spider silk is empty, allergenic stereo, and 100 percent biodegradable. it consists of structural proteins that make it a fascinating material. in fact, when it comes to mechanical stress, it's the strongest material we know of. spiders, so can bring large insects in flight to a complete stop. it's a safe, we're all familiar with. but being the scale really puts it into perspective. so many, if you wanted to stop a boeing $747.00 on approach without engines or breaks, you'd only need a thumbs thickness worth of spiders. so right inside, you'd need a lot of space because spider so stretches. you'd need about 3 point those kilometers and ends, but the plane would come to a complete standstill. come off, can you meet the bracket and go through some common spiders? so because the holy grail of materials research but breeding spiders in large

numbers and harvesting there. so naturally isn't easy. because spiders are cannibals in a farm, they would just eat each other. but despite so many laboratories around the world feverish, the working on it attempts to recreate this, marvel of nature have always failed. the biochemist thomas tribe is one of the scientists trying to recreate spite yourself and to harness it's amazing properties. to do that easy, using genetic engineering and bio technology, the piece approach is to copy the piece of dna from the spider's genome that's responsible for the spider. so protein and to then insert it into the genetic material of bacteria. they would same produce the spider. so protein and release it

to the outside where it to be harvested the but it's not as simple as it sounds. and many researchers, including trauma, shribel, have failed to put it into practice. but then shribel spotted with the mistake by july, the gene for spiders. so consist of numerous individual blocks of dna represented here with lego bricks. researchers usually connect the dna blocks together using additional smaller pieces of d n a. so the result is not quite an exact copy of the gene. the. so what would happen if you left down to connecting elements and there was a way to seamlessly connect the dna sequences for the spider. so protein the the

molecular tools to implement this new ideas didn't yet exist. toma shribel and his team spend to years inventing and developing the methodology. so it was for the exciting thing about the process was going to get why has no one managed just before? what's so special and so different about the spider. so proteins, if that makes it not doable, if most of our motto was failures not an option. we were firmly convinced that it couldn't somehow be done in the most of us. and they were right. the gene did eventually manage to get back to area to produce spiders. so, but to produce it in large quantities would require enormous amounts of bacteria. that's where the bio reactor comes in. inside the machine, researches can give us a bacteria, all the nutrients they need to produce the spiders. so protein on mice at the end of the process and they're left with a solution that's full of a coveted material. the next total is turning the protein

into a thread it took the gene chain years to understand the chemical and mechanical processes that happened within the spiders body so that they could copy them and carried them out on an industrial scale. and eventually they also managed that to create the 1st, artificially produce the thread made of spider cells which crystallizes from the spider. so protein in a special solution is the 1st us then be able to bio technologically produced by just so proteins on a large scale. but because that was a you'll, you'll become a major and it allows those a lot of interest from industry. i'm interested cubic toma shribel also managed to slightly modify the genes for spiders. so which means his grades from the labs are now even more elastic and stable than natural ones. they've named the new thread bio steel. for demonstration purposes,

they even made the 1st speakers out of artificial spiders. ok. what else could the future bring? because if it's the last disagree, there are lots of potential applications for spiders, so it could make clothing much more durable and protective. after all, spiders self is much stronger than the careful are in a bullet proof vest. the material is longer lasting and more resilient than any plastic humans have ever produced. and it's biodegradable spiders. so it's a miracle material that is short to play a big role in the lives of future generations. the whether it's clothing packaging or drinking bottles. most things made of plastic end up in the garbage

after a short time, worldwide, less than 10 percent of class to garbage, as we saw in coats. because recycling is expensive and labor intensive. stores have an india of once to v that work to a machine that can recycle 500 tons of plastic a day the trash as far as the i can see in rivers involved landfill sites listed in the streets. this is bungalow india, but it's a wealth wise problem. growing populations mean the fml waste is produced. some animals feed on garbage. that's too much waste for garbage collection services. to cope with the beta r m decided it was a problem. she could no longer renewal. the guys in the house then done all this but the but

unfortunately, despite the rules and regulations like the ones you'll see the on the slides, there wasn't the collections and millions of dollars being spent to create of adams . this is how the streets of my country all for that matter. amy, either developing countries looks like when to fade to r. m was still an engineering student. she developed the technology to segregate waste into fire degradable, unknown biodegradable components. and so the technology to reuse them 70 taken a good if i paid if you're not able to recycle the oldest the transfer case for the landfill. so yeah, that's a waste of land. you may need to look in developing countries. there's a shortage of space and system and then again, i mean like, looks like waste is in center right off working in the dump. it took us 3 to 4

years of working and the those to develop on machine watch a lot. but both it's separate or 200 tons of dry and what waste every day? the meaning by degradable food and the number of degradable waste up. you know, also they use top haven't savings to found the business trashcan in bungalow 2 years later, she employees 50 people. the crews found us. our of jane gave up his job as an economic advisor to go into business with the family. but anyway, the announcement from when i 1st met ebay, that at a dumpsite, i saw a woman who was separating the plastic waste with their hands to load up. the other thing is up to pick at that time waste pickers used to manually separate the waste . any the local is the typical hot fix that's going to get you to the young, quick, dignified. so we decided to develop a machine to help these people. so they no longer have to use their hands when

handling waste the high tech here. the 1st customers were like low seventies. and see the best thing about the prescott is. nothing was the rest here. for the rest becomes the menu for the davis comes, it is produced like gold and made as different from nature best went of that's the basic principle. salting plastic waste from organic waste. this gets recycled into an old comic fertilizer which is sold to farmers in the region. the plastic is shredded salted under cycled into furniture, shelving chest and tables. of the we are focusing on certain applications that focuses on that strength. so this

isn't what the proof would be 100 plus in order to get this done, wasteful and best buy could, can be recycled again and again, and josh calling, meanwhile, selves it's machines and bangladesh. nicole, i'm at least the young indian entrepreneur is hoping to solve the wealth waste problem. one, i'm so up to time pains and bonuses also contain micro plastics present in binding agents. for example, particles end up in the air when painful sprayed force. i stick to the wall until the paint withers and falls off. that's why this have up to the fiji. seen this a loss of micro plastics and the so what effect is that, how the lump sum field research in berlin's malware park psychologist from the cities free university

collect soil samples by a graffiti wall. oh yeah, that's good with the they want to measure how much micro plastic deride from spray paint is in the ground. the at the end of this study is about finding out whether pigment micro plastic particles are in the soil, particularly important. that's why we've come to this place in berlin, where we have the highest likelihood of finding pigment particles the most toil. okay, that's my pigment, particularly, and the micro plastic that goes along with it. that's important from that i'm groups and is the result up to $25000.00 particles per gram. the highest concentration of micro plastic they've ever measured. this shows the researchers how much urban soil can be polluted. a construct zoning, the base. yes it is,

and that's what it's cut off. the concentrations that we're finding here are obviously crazy, but we live in a very colorful city. so everywhere we look, we see painted surfaces and all of us of paints, plastic as a binding agent problem. that's why we assume we'll find these pigment plastic particles in the ground where ever we look at these a pick min plastics, i think. but i think that an important will be shown. the researchers have developed their own method of measuring the pigment plastic, because soil can be filtered like water. the, the, what's interesting is when you look at the soil like this, you can see the material it vanishes into the ground, straight away opens and it's also incorporated right into the soil. it becomes the soil. so if you look at it without these extraction methods, you won't see a thing. but the microscope shows exactly how much micro plastic is in the sample.

target level watches. let's, let's completely photo here. what you see here is just the millimeter, and it's really completely full of these particles. so it's actually quite breathtaking. it is often below even at 1st glance, the pain particles differ greatly. plastic is a complex problem. this must published and that's what makes is micro plastic problem so interesting, but also so difficult to solve. unlike other pollutants, we don't have a particular substance that we can concentrate on because it's almost a whole palette. in this case it's actually a pallet of pain type thing, but also a power plastics of forms of sizes can still from, from foreman from to worse. and it's not just threw paint that plastic ends up in the soil car tires. foil covers on fields. polyester, clothing, they all the residue,

it's estimated that humans that produce more than 8000000000 tons of plastic. so far. most of that can now be found in the environment about to use village wants to find out what consequences that has on plants. the experiments with various types of plastic, like films, phones and granules, each has a different effect on the soil. in this green house, his team is studying how fibers and the soil effect plants, grasses and other plants are under drought, stress. the soil in their ponds has been purposely enriched with fibers. similar experiments produced some surprising results. yeah, me on by the 1st studies, especially those with plastic fibers, showed that the effect on plant growth could be quite positive. who has biologist that surprised us? because this material clearly doesn't belong in the soil, but at the community level, this leads to a shifting community composition and plant diversity,

sometimes in an unwanted direction plugs. sometimes open will continue to be still less diversity due to plastic fibers. though these can also loosen the soil in one field experiment really team expose plans to 10 types of stress. pest sites, solid war antibiotics act alongside sheet or dryness and tire abrasion. for a while, you could see it quite nicely and it looked like the structure together on the soil surface when you. but looking here over a year later, the materials almost disappeared. and clearly it's been incorporated into the soil . the experiments simulates global developments. micro plastic is only one of many evils here. and that really says is a problem. the business list, new a plastic, the effect of it was also known. so it's not just plastic that causes an effect, but plastic together with other factors and. and that's the emphasis of this

experiment that we study this multitude of interactions with other factors. and there we saw a very clear effects after just one year use of the more factors you activate, including tires with tire, abrasions, and so micro plastics. the more the production of plant bio mass decreases. if you put the fewer pollinators, visit the fewer flowers there are. and in the future, we'll metrowood consequences that has in terms of biodiversity. it means who comes off know what's important to know. the beauty of us a tape what plastic works in which way that's what really gangs to research for there by the graffiti wall in malware park. again, he's study here was just the 1st step for me. so i thought that was new for me to i didn't know that pain contains plastic binding agents. and i think creating this awareness is, may be one of the main achievements of this study to help a human, as often as a student really hopes that such awareness will lead to the development of new

plastic free pains. because he says the world would be adult place without color for was the inside the face deluxe to learn about my car. plastics. so now thanks for joining us on tomorrow today. d w sign show. see you next time. stay curious by the the
