for many im gonna working on with holiday destinations and drowning interesting ways, we rewind and the cars every year. europe exports 1000000 tons of plastic waste. is there another way? after all, the environment isn't to recyclable. make up your own mind. d. w. made for mines ah, ah, ah ah, ah, ah, it's true that protecting the environment is off. next pensive,

the damage caused by droughts, floods, and tropical storms is costly to not only is there a monetary toll, but a human one to a natural disaster can destroy lives and livelihoods in minutes. yet green industries can be a money spin of the economy. here in germany, they're worth over 70000000000 euros a year and employ more than 300000 people greening the economy. that's our topic to day on mate. one of the advantages of living in a city with lots of parks, there's always a calm oasis to get away from it all. but there's more to greenery in cities than meets the eye. plants and trees help to filter harmful gases out of the air and help cool down the city on a hot summer day. it's also become a lucrative business as our reporter eula hind, which man chose. there's room for green space is pretty much anywhere. ah many cities in the world suffer from smug deli is regularly hard hit,

breathing in such polluted air as a real health hazard. tuna is among the places looking for new solutions. it's one of india's most important industrial hubs. and yet home to many of the countries showcase green projects. the one earth campus, for example, was built by seuss lawn earth, one of india's biggest renewable energy companies, to house it's headquarters. endeared a big trend of making would become glass boxes. and there was a lot of opportunity for them, but then the management and the chairman of the company decided to what ways we should be into such non efficient buildings. being a renewable company, diesel said in global example. right, and that's where the whole study stocks the campus is self sufficient in energy with rainwater harvesting and gray water recycling. there are many green spaces unusual, 20 years ago when the site was built. let switch location german cities like

berlin also suffer from air pollution despite having many parks and comparatively strict pollution limits. some german cities have even imposed diesel driving bands in the past. this project could be part of the solution. handling coal cells, tiny forests to companies. he simple and cheap onto the quote. in principle, it's a piece of primeval forest, brought into the city. in this system was developed in the 1960 by japanese botanist r. kiera, milwaukee. all he tries to imitate nature forests, either primeval forest, divide. that means this is the community of trees rather than isolated urban trees, as is often the case in the city wide sustained. and boy and that rings huge benefits is building. please give me enough. for example, here in cologne. a real estate company has decided to plant a tiny forest on this empty lot as if you will just go. she croz image is

important. it's also important to our tenants. she looks, if a place looks good, it's also more pleasant to live in shock to be involved should do before she's i can imagine that many companies will follow our lead by this. a lot of real estate development has those little decorative gardens and the paved over surfaces. yes. and those are a mistake. you go there, not healthy fish does finishing that to india horn as authorities enjoy their green image though they know that the city suffers badly from air pollution. that's one reason why puna has massively expanded. it's like pants in recent years with the city also wants to be a trailblazer in india for sustainable architecture. commercial buildings will really help in reducing the climate footprint generate of really a part of climate action. and that is with and use the lighting of more efficient

cooling, reducing the need for cooling and heating in the 1st place. natural ventilation natural lighting. one example is the forest school created by architect neural kareem, which is due to open in 2022. it's an unusual design, petering a green facade, a bank circuit on the roof, and green a tramps. the design basically explores the relation between nature and better got you, dennis, of in certain lives. so the foundations of the school doctrine of forest, based on the idea of grow our lawn reuse, plotted play, tuna is blooming with new construction. a story housing has one of the biggest builders. it's director says green architecture is also profitable and less energy consumption means lower emissions and less smog by nature. we are not sustainable. you know, because the other end of the day we are treating large monoliths of concrete and steel. and you know,

in norway as the mining of steel or the manufacturing of concrete or most of them are deals that we use a sustainable. but in the way be design these buildings, we can make these buildings last longer. a few examples of how we can do that is maximize the model light that comes in. right? so we give floor to ceiling windows lodge openings for windows. so that is a lot of wind and natural light coming in. so you reduce the need for air conditioning and for artificial lighting. and back in cologne, germany, a dozen companies have already placed orders for a tiny forest. but the price tag is anything but tiny, $40000.00 heroes per $760.00 trees and shrubs and 20 square meters. the density and variety of plants means they will grow quickly. good for the and it's an investor's says the founder babble. zip kima, green and climate friendly will be a big selling point. conf. with there are 2 of the companies that can boast, green, surroundings,

and real sustainability will be more attractive to customers and the community often or no one knows exactly what green cities will look like in the future. but tiny forests and sustainable design, we'll all do their mid to improve herb and air quality. b, as in india, or germany. and staying in cities, his something we don't think about often until it goes wrong. managing water and what happens when there's too much of it? europe had its fair share of floods this past summer, causing 30000000000 euros worth of damage. and germany alone and around the world, some cities may even be totally under water and a few decades due to rising sea levels caused by climate change. city planners and the building industry will have to adapt. we take a look at 2 cities, bangkok and berlin to water came slowly like a monster and starts getting weaker, weaker and weaker,

and everywhere from bangkok to berlin flood waters. no, no, borders my mind and my balance, i feel always think of bananas being flat tongue, but when the city experiences heavy rainfall ground that dips like just a meter can fill up with 50 or 60 centimeters of water underground spaces got flooded. hello, i'm out thailand's capital city, bangkok has been hit especially hard by climate change. the city is only one meter above sea level, which keeps rising at a rate of 5 millimeters per year. scientists predict at the city could be under water by the year 2050 alex face is a graffiti artist and parent who's worried about the future of his home. and building my house right now. i spent a lot of money to building my house. i'm always thinking in ha, okay, one day i would think it'd be under the see anyway. and somebody was saying in

a happen in very soon in the next 10 years some stretches of land have already started thinking. for example, around the sandwich in temple only 20 kilometer south of bangkok. the ocean moved to the land, the last 50 years. so the local people need to move to house. drainage systems are also hitting their limits like here in berlin. heavy rainfall overwhelmed the infrastructure, leaving it unable to handle the massive volumes of water. this causes basements, low lying building entrances, and subway tunnels to flood engineer come and zika from berlin, city, water management, design, so called decentralized rainwater management. like most cities, berlin has a sewer system, but it can't always cope. event is expand looking agnes attack because heavy rainfall has increased. the waste water systems can no longer drain that volume of water from i. volcanic map light warned us compton and quincy and that's when you

get over a flyer on a lease that's own aba i'll and large volumes of surface run of water the collect and lower lying areas in banking, dash baptism in to help tackle the problem. berlin aims to become a sponge city. the idea is to capture rainwater, like a sponge, seaters and in board. and then it can be drawn into the soil buffer house that's good for the water supply and has all the benefits, like urban greenery and climate that came up. and yet house to prevent flooding. little tamma. since 2017, every new housing development in berlin has been built according to the sponge concept. a pioneering example is this residential area and se berlin. since 2018 berlin has been advised by a special agency on new constructions and rainwater management. hunter krueger explains how in this development, not a single drop of rain water ends up in the sewer. yes, the fatigue would, i can, ma'am. he, you can see the vast green re on the rooftops with that. that's one way that rainwater is captured. and from there, it evaporates with the hired movie duff. i don't study as much as 90 percent of

rainwater can be captured in this way. run off water flows through pipes into special drainage basins. there are also low lying flower beds paid areas that are not sealed, and gaps in the curves that allow water to pass. but the rainwater agency says only about 4 percent of berlin's rooftops have plants like this. the sponge city is still in its early phases. back in bangkok, the city also wants to tackle flooding with green rooftops, like in berlin. it helps to use them for temporary water storage. so the rainwater can be put to good use. that's just one of many ways to give nature a chance in concrete jungles. more importantly, it's an attempt to prevent catastrophic flooding in the future. i think they can do that. but we need to, when everyone, les, hey, wake up and see what going to happen. and we need to fix it to get plastic

bottles can either help or hinder our efforts to be better to our environment. when rubbish is dumped in the ocean, plastic waste can hang around for decades causing harm to marine life. but when recycled bottles can get a new lease on life, the coming fresh new bottles, all making their way into everything from packaging to park benches. but how does a mere bottle become something new? and how is industry innovation transforming that process? christian practice has the answer around the world. mountains of rubbish, a piling up. plastic waste is especially bad for the environment because it doesn't decompose. $1000000.00 plastic bottles of sold around the world every single minute to produce just one of those bottles. it takes a quarter of a liter of mineral oil, but there's one type of plastic that's cleaner and green up once used. p e t

baffles can be crushed and processed into granules, which can then be almost a 100 percent recycled to manufacture new bottles. but how does it work? oh, a recycling company in germany, full 100 bales of bottles are delivered here every day. one, bail weighs about 250 kilos and consists of approximately 10000 bottles. it might look like waste, but these bales have that price. dyson vacuum. i'm hoping this is valuable raw material. so we have to pay for the bail seo design. but kansas, they cost roughly $300.00 to $500.00 euros per ton. we'll put on the 1st step is to release the bottles from the bundle and separate them on a conveyor belts. all of this waste is p e t polyethylene, to rest the late for an obvious reason. as endorse loves to fight up in germany, the consumer pays a deposit when they buy bottles. $0.12 for

a single used bottle and then if they return the bottle, they get the deposit back. i'll do it up. we'll soon as i bought, getting up so here in germany with our deposit and return system has clearly defined standards law because the quality rivers vending machines can be found. in most supermarkets, you insert your bottle and get a 25 cent voucher in return. germans are reputed to be world champions in recycling, 97 percent of bottles, and now recycled. here. other countries don't have anything like the same number of river vending machines. so the recycling reaches far lower. the bottles assorted not only by color but also by material material. the system recognizes any material that isn't p t. that also gets recycled, for example, labels and garbage bags. in the next step, the bottles

a shredded and washed at a temperature of 80 degrees celsius. then the fragments is stripped of any remaining residue, leaving pure p e t fragments known as p e t flakes. this machine has to scan vast quantities of bottle fragments. a laser scans the pallets a 1000000 times per 2nd, identifying parts that still need to be separated. this is where the machine was developed. machine manufacture out when is and saw in south germany. the prototype was designed by stephanie cliques, father, a physicist. that is of its own. com. the flakes are in this section. the flakes are sent down the channels, and at this level, they reach the laser. eva, the laser focuses on the flake of the flank, absorbs the energy, and then re releases it in the form of res, which re enter the machine and are analyzed by

a spectrometer oscar vegetable. the company has already sold over a 100 of these sorting machines and sales a likely to jump the e u wants to increase the share of recycled p t in plastic products. not just in bottles, but products such as yoga pops to your good job and mercy and they will um, fix light on the e. u as aiming for a recycling quota of 25 percent by 2025 guns orland. why 1000 dies from pies? he puts an end aiming for 30 per cent by 2030 is was on the muscles outside 1000 since 2019. we've been seeing a growing demand for recycling machinery in our fargo. not my daughter, christina. the p e t. recycler uses high pressure to melt down the pre sorted flakes at a temperature of 280 degrees celsius. the process

results in these granules. they can then be sold and used to make new bottles, which in turn can be recycled. a number of times 5 could the same process be used to recycle other products. because of the are, the main thing is to have reverse vending machines which allow us to extract your plastics. so yes, this process could be used to recycle other types of packaging ego, the granules, the delivered to bottle manufacturers in big bags. it's more expensive than standard plastic, but environmental regulations obliged industry to use recycled material. the recycling company is already planning to construct a new plans. bottle. recycling is a well functioning system, but if we want to reduce more of the world's waste mountains, a lot more p e t packaging will have to be recycled. recycling petty bottles works well,

but not all types of plastic lend themselves to reduce. that's why the likes of germany in the u. k. of camp bound on single used plastics, like straws and cutlery. these often just end up being burnt or buried to get rid of the waste. neither very good options when there are alternatives out there. i'll next report, take a look at some up and coming packaging alternatives made from some rather unusual materials. we all know plastic is convenient, durable, and everywhere. and at the same time, plastic killers, marine life contributes to global warming and poses health risks. but what if we could use all natural materials like mushrooms see we'd or would to cure ourselves of our addiction to plastic? what are the alternatives out there? and why aren't they everywhere?

we start working with sewage as an untouched material and to try to basically develop a range of new solutions that are completely by the gridable natural. and sometimes even edible peer pathway is the co founder of not law, a startup that uses seaweed to replace plastic packaging. sewage was always a good candidate for us because it grows very fast. some of the sued the reuse can grow up to one meter per day, and in terms of and the flight, it's been around 400000000 years. so nature has no problem dealing with, it's anywhere it ends up in the environment. and that happens a lot with plastic. 40 per cent of plastic produced is for packaging. in 2018, just 13.6 percent of plastic containers and packaging were recycled. to counter this? no plot have developed little sashes for sauces or drinks made from algy. and so

you can eat them along with our contents. and even if they're not consumed and are thrown away, not le claims they will buy degrade in 4 to 6 weeks. to make these vanishing sashes, not blood dries and grinds up. brown seaweed, a special machine, then turns the powder into a membrane that can be filled and finally sealed. oh, ah gbc with no, we really target cases of instant consumption out of home or things that are used very quickly where to be consuming, he's going to be able to have the functional properties too, that you are the packaging. humans that is required, but that has also the best sense of be reintegrated in nature. each will fail to collect your thoughts on the right bit. the firm also makes a special coding for take away containers. usually,

they're coded with plastic to grease proof them. but that makes them hard to recycle and also makes them non biodegradable. not the solution however, is made from you guessed it. weed, which means that the boxes should palm post and 29 days solution to a growing problem. seeing that a recent study found food containers to be among the 10 most common items polluting the c sound huge. we can make plastic, so sasha waste simply unsustainably disappear. but to be precise, the trial is only running in 11 restaurants for now. and speaking of production, the custom made machine that makes the seaweed south chaise is still being trialed . so it's not turning out big volumes just yet. but seaweed is not the only

promising material out there. another rapidly growing substance and a favorite of a little italian plumber, the mushroom or to be exact. my celia, my celia mar, the roots of mushrooms that form an underground network called high fe. if treated right, they can be turned into a form that is a sustainable alternative to polystyrene all natural and completely by degradable. how on earth you turned mushrooms into packaging material you asked? well, you put organic waste products like straw into a mold and mix them with mushroom spores. in the space of a week, the mice jojo will feed on the waist and grow into the empty space. the resulting my sylium foam is van removed and tried to prevent the spores from growing further . it's water and flame resistant, lightweight,

and actually stronger than traditional polystyrene. mm. there's things going to happen. don't. we can't even dream of today. diane birby is the c e o of grown bio, a dodge company that produces my sylium packaging. 35 years ago, roughly 2 elder small and medium companies, reduce the environmental footprint of their packaging. and i, somewhere i found the term mushroom packaging, which brought me to, we created young's company is a licensee of eco vate, of design, the inventor of the material, one of the 1st companies to adopt my ceiling packaging was hardware manufacturer, dell for selected shipments. others looking to foster a green image like lush, have since jumped on the bandwagon using it for a limited edition gift pack. the 1st drawback, though, is that it's way more expensive than polystyrene grow and bio didn't disclose any prices. but one study estimated the cost of my seal young could be around $3.00 per

pound compared to $0.04 for styrofoam. the 2nd problem, it's hard to scale up production. the packaging grows in these containers for 5 days and takes up a lot of space while doing so. i kia announced its use of my ceiling packaging and 2020 only to abandon it a year later. because of the lack of scalability on an industrial level. it's certainly not yet at the level of styrofoam, and even if it would be possible to make it at the same cost, then you still need to scale up enormously, which just takes time to build all those factories. but also because even though we say this is our alternative, it's not one on one alternative. even though our product extremely light, styrofoam still ways affect or to lighter than ours. there really are quite some

brands will say. i don't mind being more. this is just what we should use iq of aid of recently received a $60000000.00 investment so they can scale up their production and potentially lower costs. the big question is whether it'll become cheap enough to truly compete with polystyrene on a large scale. there are alternatives to plastic out there, and yes, big brands are dipping their toe into the market, but prices are still high. and despite all the big brands cooperating, the scale is extremely small. raising the question whether they're going into the market for the right reasons. because if big brands don't adopt more sustainable alternatives, this will continue to be a niche market only to reduce or plastic use as much as possible. we need to create all natural scalable alternatives for specific use cases.

and that's a wrap from us. of course, climate and environmental protection are far more than an economic factor they're essential to protecting the planet for future generations. that's all for this edition of mate. thanks for watching c c. ah ah ah ah, with

who 0 one continent. 700000000 people with their own personal stories. a everyday life with

what europeans fear and what they hope for focus on europe in 30 minutes on d. w. and to the conflict zone. no sooner had president putin annexed for regions in ukraine, and these troops were forced to flee from a key city. and one of them for humiliation wasn't lost on russian commanders. i guess this week from care of you who are short craft deputy head of the presidential administration as you, craig back to the food and into a corner where he might use his nuclear conflict zone in 90 minutes on d, w o. d r e a. and the pillar of sticks and society,

a symbol of arbitrary rule in the struggle for justice. taxes the right to levy taxes and the obligation to pay them. both inherent in the sovereignty of the nation, states had their citizens. but what happens when the power of taxation is undermined a tax on top of the tax on top of the tax. that's the rule that broke the camel's back. i've been rambling forever, thinking to myself, when is it all going to come crashing down your pay won't pay. taxation and politics starts october 21st on d w. ah,

ah ah ah. this is d w. news line from berlin, ukrainian troops re take more of the territory illegally annexed by russia. ukrainian president, the landscape says the army making fast and powerful progress as the russian president signs final annexation papers.
