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 today on mate. one of the advantages of living in a city with lots of parks as always a calm oasis to get away from it all. but there's more to greenery in cities and 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 julia high investment shows, there's room for green spaces pretty much anywhere. ah many cities in the world suffer from smoke. deli is regularly hard hit, breathing in such polluted air is 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 so long earth, one of india's biggest renewable energy companies to house it's headquarters in get a big trend of making would become glass boxes. and that would rodolfo opportunity for them. but then the management and the chairman of the company decided to my wife, we should be in both such non efficient buildings being a renewable company resource set 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 called sales. tiny forests to companies. simple and cheap on shaquilla in principle, it's a piece of primeval forest, brought into the city. this system was developed in the 1960 by japanese botanist r kiera, milwaukee. or he tries to imitate nature, forest sighted primeval forest light. so that means this is the community of trees rather than isolated urban trees, as is often the case in the city line 16 and boy. and that rings huge benefits is building. please give been, for example, here in cologne. a real estate company has decided to plant a tiny forest on this empty lot, which was actually just again, she cross image is important. it's also important to our tenants. she know if a place looks good, it's also more pleasant to live in shockley in hong should've been fortunate. 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 here. and those are a mistake they're not healthy, which does include bank to india. ponies authorities enjoy their green image though they know that the city suffert's badly from air pollution. that's one reason why puna has massively expanded its flight pants in recent years. but the city also wants to be a trailblazer in india for sustainable architecture. commercial buildings will really help in audit your thing though. climate footprint annoyed was really about of climate action. and that is weird though it and use the light thing of more efficient cooling, reducing the need for cooling and heating in the 1st place, are natural ventilation natural lighting. one example is the forest school created by architect no rou, kareem, which is due to open in 2022. it's an unusual design featuring a green facade, a blank circuit on the roof, and green a tramps. the design basically explores the relation between nature and better got you in dennis oven settlements. so the foundations of the school doctrine of horace based on the idea of grow our lawn reuse plot to play. cona 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 are viewed as 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 there's 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 tenants and investors says the founder babble, look, kima green and climate friendly will be a big selling point. comes with data to the companies that can boast. green, surroundings and real sustainability will be more attractive to customers and the community. often. no one knows exactly what green cities will look like in the future. but tiny forests and sustainable design will all do their bit to improve herb and air quality. b, as in india or germany and staying in cities has 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, 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 watch a chem 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 berlin as being flat tongue. but when the city experiences heavy rainfall, if the ground that it's 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 that 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 wasn't gonna be under the see anyway. and somebody was saying in a happen in very soon in it next 10 years, some stretches of land have already started sinking. 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 khan 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 a expand looking agnes attack because heavy rainfall has increased. the waste water systems can no longer drain that volume of water. and i factory map like wonders, compton and quincy, and that's when you get over a flyer analysis. so an aba op and large volumes of surface run of water the collects in low lying areas in banking dash baptism in to help tackle the problem. berlin aims to become a sponged city. the idea is to capture rainwater like a sponge system 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's tamma. since 2017, every new housing development in berlin has been built according to the sponge concept. a pioneering example is this residential area in se berlin. since 2018 berlin has been advised by a special agency on new constructions and rainwater management. hun krueger explains how in this development, not a single drop of rain, water ends up in the sewer. yes, the fatigue woods. 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 higher need of had done that 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 we can do that, but we need to, when everyone, les, hey, wake up and see what's gonna 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 becoming 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 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 t bottles can be crushed and processed into granules, which can then be almost a 100 percent recycle 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 lunch. if i have been germany, the consumer pays a deposit when they buy bottles, $0.12 for a single used bottle at the said, then if they return the bottle, they get the deposit back a little we'll soon as i bought here. got 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 supermarket. you insert your bottle and get a 25 cent voucher in return. germans are reputed to be well champions in recycling, 97 percent of bottles, and now recycled. here. other countries don't have anything like the same number of reversed vending machines. so the recycling rate is far lower. the bottles assorted not only by color but also by 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 has 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. and he says its own calm, the flakes are in this section, the flakes are sent down the channels of the end. 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 rays which re enter them sheen and are analyzed by a spectrometer. oscar that's good. the company has already sold over a 100 of these sorting machines and sales a likely to jump the e you wants to increase the share of recycled p t in plastic products. not just in bottles, but products such as yoga pops to your quote, your armed mercy, and indeed all on fixed right. on the e was aiming for a recycling quarter of 25 percent. by 2025 guns orland site has entices from price he puts and, and they're aiming for 30 percent by 2030 is was on the was also $5000.00 since the 2019. we've been seeing a growing demand for recycling machinery off fargo. not my daughters, 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 reversal vending machines which allow us to extract your plastics. so yes, this process could be used to recycle other types of packaging. diego, the granules are 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 p t 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 camped down 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 seaweed, 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 plan have develop little sa chaise for sauces or drinks made from algy and so you can eat them along with a 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 quite dry and grinds up brown seaweed, a special machine, then turns the powder into a membrane that can be filled and finally sealed. ah, it's a beauty with not are we really target cases of in some consumption out of home or things that are used near quickly where to be consuming is going to be able to have the actual progress is to deliver to packaging homes that is required. but the high is also the best sense of being reintegrated in nature each. we fail to collect a thought on the right. 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 low solution, however, is made from you guessed it, see weed, which means the boxes should palm post and 29 days. but solution to a growing problem, seeing that a recent study found food containers to be among the 10 most common items polluting the c sounds huge. we can make plastic, so sashi 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 al trinity of to po styrene. all natural and completely by degradable . how on earth you turn mushrooms into packaging material you asked? well, you put organic waste products like straw into a mold and mixed them with mushroom spores. in the space of a week the my seal young will feed on the waist and grow into the empty space. the resulting my ceiling foam is been removed and tried to prevent the spores from growing further. it's water and flame resistant, lightweight, and actually stronger than traditional polystyrene. there's things going to happen that we can't even dream of today. diane birby is the c o of grown bio, a dutch company that produces my celia packaging 35 years ago, roughly to out her 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 the 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 scale ability on an industrial level, it's certainly not yet at the level of styrofoam. and even if it would be possible to make you get 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 is a factor to lighter than ours. there are really are quite some brands will say. i don't mind being more. this is just what we should use iq of 8 of recently received a 60000000 dollar 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 nice 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 rap from us, of course, climate and environmental protection are far more than an economic factor there is central to protecting the planet for future generations. that's all for this edition of made thanks for watching caesar. ah ah ah ah ah, with who on the road, with caravans along the ancient trade. we discover a country between prefabricated buildings and 1001 night between nomadic tradition and modern life style oo discover. because tom travelling the silk road by train in 15 minutes on dw, teaches us searching for this student. in a fatherland, brazil. many children have lost contact with the school. a consequence of the school cleansers during the pandemic. the which is our campaigning for them to retire. they know without education, these children have no chance. google 3090 minutes on d. w. ah no has no limits. love is for everybody. love is live. i love matters and that's my new podcast. i'm evelyn char, mom and i really think we need to talk about all the topics that north divides and denied this. i have invited many deer and well known guests, and i would like to invite you to an end the or eternal program dynamite. and the pillar of sticks and society, a symbol of arbitrary rule and crucial tool in the struggle for justice. taxes the right to levy taxes and the obligation to pay them both inherent in the sovereignty of nation states and their citizens. but what happens when the power of taxation is undermined with won't pay check sanction. oh, so it's up to between 1st on the w ah ah, this is debbie news live from berlin. ukrainian troops retake more territory as they make rapid advances against retreating. russian forces. president zalinski says troops have liberated dozens of towns in the past week. ukrainian forces are now pressing their character offensive on 2 fronts.
