even if they are trying the connection, the connection of the issue be in india is where most of the ways gets collected. but the problem is most of it gets collected in an informal way to collect a large role in south and southeast asia and africa. when they pick out plastic from unsophisticated ways, it is often contaminated, which means it's recycling value and the amount that can be recycled. a significantly lowered western countries also often export that waste to developing countries which adds to the burden back in germany. one reason the streets do look cleaner is the deposit system. it also means that uncontaminated waste with the recycling value gets systematically collected but hasn't met if other additional objective of moving towards a greenow system. research shows that since 2003,

the share of plastic refill above the market has actually significantly dropped. one reason is that supermarket giants have had the financial power to stick to single use in order to streamline the return process. countries of the global not including germany, still produce much more packaging waste than those in the global south. so the most environmentally friendly solution would be to reduce that 2nd place goes to refilling and then recycling for my boss, i started getting my own water bottle, so i need to use the amount of waste that i created on the state level. of course, you can push for policies like germany's that have proven to work for reducing and reusing muscle. now trees need water just as much as we do, if not wall trees and cities often locked in the middle of concrete and store and need extra k that are more than 400000 trees in germany's capital city. berlin and

some of its residents have developed a project to make sure they're looked after. water at berlin has experienced 3 years of below average rainfall and the trees are dying out. ready a tree needs at least 10 of these watering cans of water a week. this group of volunteers wants to be part of the solution. they've gotten together today to water their cities, trees as hazardous lessons, norma last summer, the tree in our backyard dying because it couldn't withstand the drought and it was just gone and i thought the ones in front of the building might be next. and i didn't want to see that happen the next then before i'm home on religion is a project based at berlin city lab, set up the neighbourhood watering initiative online and in the platform shows how much water the different trees need. city lab is

a nonprofit foundation based in the german capital where innovations are born with the aim of making the city and more sustainable. the data comes from the city administration, with daily weather updates and information about whether or not the trees have had enough water. given, you know, this map contains more than 625000 tree points, range tree and you can find out what type it is, the age and its water requirement in that's what we have for now. but there are other features we could include. i was like the high, the diameter of the crown, the diameter of the trunk. it's really exciting, especially in terms of watering. you could almost 2000 berliners have registered so far. some of them just water trees occasionally. others have taken responsibility for a single tree on their street. or land has 2500 parks there. the

green lungs of the city, the trees improve the climate and filter out exhaust dimensions and more people are becoming aware of their importance. there are now several environmental initiatives in berlin. this neighborhood enclosed back at some regular gardeners. today there's bruising up the flowerbeds and planting bulbs for next year's flowers. we're all in this together, regardless of where we come from and it's a global environment. so we planted flowers and different sorts of things to have a healthy environment to bees. and above all, we just like getting all these people together to do something together, the happy to be together. the watering group has their work cut out. there's been no rain for nearly 3 weeks. the volunteer can easily stay on the app, which trees need water. they're hoping the initiative will spread beyond berlin.

when comes off, i'm still here, but you could use this platform for other cities because an open source. in principle, any city that has a train register available, and that has weather data, which is most of them i could implement this app themselves. that's kind of the volunteers will keep up the good work until winter, helping to keep the 30 trees of berlin alive. are planted to need for water is only increasing and never decreasing. treating water may be a useful solution to meet this rising demand, but there are technical challenges to achieving this. and even if it's block is crossed, people university frown upon having to consume treated water. a company in delhi is trying to change this by demonstrating how sewage water can be converted into safe drinking water. the,

the yamuna river delhi most important source of drinking water at the cities northern edge. it's still quite clean, but it's a different story entirely once it leaves the southern parts of delhi. because all the city sewage flows into the river, including industrial waste water, from the lease is up. so what your biggest problem in delhi today is the availability of clean water will a lot of work has gone into cleaning efforts, etc. but there is an urgent need to address the issue of making more water available demand phase calling. you can do public zation is occurring rapidly and with it, the demand for water is rising just as fast can carmen. similarly, these other ones could help solve the problem. that part of the facility designed to transform waste water into drinking water. in many parts of the world, treatment plants only clean sewage to a certain extent. before re directing the water back into the rivers. the new

method aims to change that to a single came up with the concept together with her father after she was angered by the water quality in their home. this whole idea came about is also because i have seen personally in my own home where the switch line and the drinking water supply line normally gets mixed up, especially in the veins. so at that point of time, it is, you know, it was, it was crazy. i mean, you could mail it in your, by your be being, you know, we were having a prob, stomach issue. we were having infections and all that kind of stuff. so it was about what can one do about this, and i've seen kids being and would what though, you know, it's quite disheartening to watch. so that's where basically the whole concept came about the jelly job board, the government agency responsible for most of the city's water supply, installed the plant and it's cash per se, right? in west daily run on solar power. the absolute water facility generates 100000

gallons of clean possible water each day and help clean up the rivers. sewage is collected from surrounding districts in tank containers and trash and tiny plastic particles filtered out of the waste water. it's then sprayed over 5 layers of bio filter beds filled with wood, chips, pebbles, and sand. here the worms get to work, breaking down the pollutants. the recycling process was developed and refined by company founder for nielsen guy who was a chemical engineer. technically the thing exist, there's some people i've done some experiments for example, using the will me coach. but at this scale it had not been done. and then the challenge was that they took operate by from 50 degrees, which experience this to minus couple of degrees. that for example,

lake and approach and then to keep those ones alive. so that required some working to do and also the toxicity that is present in the sewage. because in india, a lot of which is also mixed with industrial sewage. so it's not just domestic storage. using nano filtration technology, the water is transformed into what's classified as high quality drinking water that meets the world health organization standards. the plan to control the full 1000 liters and water every hour. the technology is expensive to install. it's convention is offset by lower running costs compared to conventional sewage treatment plants, all s t p 's. the most important thing is the operational cost, which currently in the market we are the cheapest $1.00, each of of the conventional f t p. the other most important part is that being

green we, we are not subject to very heavy equipment. so therefore i like that the cost conduction is the lowest. so all in all is a full sustainable green system, and it is constantly cyclical, as i call it, absolute waters, the various facilities. now treat some 3000000 liters of sewage daily. that's just a small portion of what deli produces. still, the firm's found is convinced that in future, 80 percent of its residents, water needs to be met using purified water. water gives us life. we need to protect it. i hope to these show his health to pink about your water use and how it could affect the rest of the organisms living on out on leave you with that talk and see. we'll get next week from all the funds in india and germany, goodbye. and thanks for watching the news
