9:30 am
germany ah, shut them, i got my license to work as this morning instructor. and now i teach children under dose to swim. what's your story? take part serious on info migrant. ah ah romantic and mysterious moon and have long captured our imagination as a western habitat in which became slant, biomass becomes piece that makes them excellent carbon things and also the focus of a great deal of environmental research. ah, all that's coming up a
9:31 am
welcome to tomorrow. today you're saying sion dw, sorry, covered 10 times as much land area, but move capture and store far more carbon dioxide that makes in tax moreland, extremely important in the battle against climate change. over the centuries, boys have been trained for farming some 15 percent of the world must have been drained and that's released as large amounts of greenhouse gases into the atmosphere. some reasons articulate the effective, such as the european union, russia, and indonesia. today, some form of good ends up being restored to restoring deputations these inconspicuous looking moreland plans around rob nation about the clock, an electronic scan, it takes readings once an hour, tracking that height,
9:32 am
wanted to size an angle of their leaves. these researches at the university of cry, fault, and ne, in germany use that. they tend to judge how well the class to growing that very water, a nutrient levels they work also involve scanning the rates in the 100 path. longer these means more heat could be home. crucial parameters when determining the best way to re wet a more must be when we've been able to re went around 10 percent of the morland's here in the northeast. and but how did those restored morris work? when it's, what we want to see is the system where carbon is retained and the soil long term for quenched off. and this set up with combined with field studies, allows us to investigate those questions to the convenient to try that does. that's
9:33 am
why we bring together the heat and the plants and the greenhouse gas flow type of food stamps were providing insights. that will be a concrete help and future land management of to hear from good the water level, nutrient content and range of plants all play a role in a more ecosystem. the wrong combination could mean a requested more ends up producing too much me thing affecting the carbon dioxide it stores striking the right balance is key in the right balance is also key when it comes to the plans that can be sustainably and profitably grown on requested more feminine of why the choice of options to the store comes from lakes streams and ribbons and his rich and nutrients. the common read also is to the material for us. what is
9:34 am
the insulation on fire proofing ah, reach, can i re graph on the common read potential buyer fuels in pilot form, replacing oil and gas. so growing them on the west is more than twice the climate benefits. animal order can also be growing for water buffalo, for example. all this means that wet phantoms often many opportunities the sustainable farming but it's a different story on upland. most. they rely only on vein mortar, nutrient content is very low. so which france might thrive here? that's another question to the researches from the university of great fault or investigating spectrum's piece most is very much at home screen conditions offered by upland moles, and cronies. here on a large scale might really pay often. when daughter,
9:35 am
when you leave with miss asked me, you could in germany, we use around 7 or 8000000 cubic meters of pete a year for horticultural, some strength, soil. that's what most of the vegetables we buy and supermarkets are grown on me just like ornamental. and then what have, you know, channels and these are off that fossil resource that's grown over millennium. but it's being harvested and used in a short period of time, which is why we're cultivating piedmont to replace it on. did he talk more that i'm using platinum to replace the peat? well, only work if the scientists can break fast growing varieties. the researchers are using this test field to see which kinds of spectrum most might be feasible option. they selected varieties from 30 more across europe, primarily from sweden,
9:36 am
no way and finland j take out a g, an, an a teens perform regular change to keep track of how the different varieties the growing, the samples they take. and they to dry and wave in the lab that allows them to judge how the bio mass in the field is increasing. their goal is to find the ultimate super moth me, stuck in a more fish gro, year round and ready for harvest. after 3 years care on experimental fields, the researches are still using a converted digger in the future. they hope harvesting machines will be able to go directly onto the fields. they'll know the spec and the most, leaving the roots in the soil to give rise to a fresh generation of peat. most way the field was to be receded off to harvest,
9:37 am
inspect them. it's not just useful as people, it can also be used in everything from insulation to diapers and packaging. it's the most versatile material, ah, that's a farming on re record more to drive. it will need the same kind of government support that conventional agriculture enjoy. germany concepts, 100002 the land that is stated to growing spot in a month. it's a sustainable and climate friendly form of farming with lots of potential for the future. ah, some of the plans that are growing on our fields don't end up on our plate. instead,
9:38 am
they used to produce bio plastics for disposable dish where for example, but can such as corn and soy are important crops that help feed the world. so using corn starch, for example, to produce bio plastics isn't really sustainable. that's why one company in switzerland has decided to investigate the parts of plants used as creating bio plastics from waste. that's the mission of fluid solids in zurich. the materials that arrive here would normally end up in waste disposal, like the old houses that have come from a mill. so how can they be used to make plastic? because that's the 1st quick inspect shows the has the suitable span. says a wide range of natural waste materials can be used to key any cellulose
9:39 am
based materials called her o hamel. coffee grounds grew as grain would powerful. we've tried more than 50 different things, but it is all new for the car began experimenting 10 years ago. but anything out as an industrial design, and so i'm curious by nature and like to try things out and we took a potatoes peeled them and extracted the starch. we tried not chilled, which we ground. and we've really been very hands on from doing basic research. and what nice sickly and big kitchen going off at some point they came up with a solid material and the very 1st prototype was born back cause i used to develop his own bio plastic. what's known as a composite 1st, the oat has the ground and mixed with 2 other components. mixing
9:40 am
is done by chemist francesca t. a binder and a secret ingredient go into the ground. this sample is still to running. trial and error is still part of lab life here. yes, i found this open, you know, we have to optimize the manager to produce plastic material. which we can then process like regular plastic, lighten, normal stuff. and this is what it looks like when the mixture has solidified. it forms a granular it the proportions need to be adjusted for each natural fiber. the 2 inventors illustrate this with their debut product soc hangers. here to the these ones, the very elastic these ones here though you can definitely feel this difference
9:41 am
within fluid solids produces hundreds of thousands of soc hangers in competition with conventional cheap plastic. the plastic market is highly competitive. in fact, it's brutal musician, i fish all till we move in chuck infested waters. ok, maybe that sounds a bit too negative for you thought of it? no, i think it happens in any industry where there are changes and new approaches are developed. so you need to find your place me and told you ground against your competitors. and what happened was the team members demonstrate just how well the soc hangers. decompose using compost soil. once buried in the compost, the bio plastic degrade in 5 weeks. the
9:42 am
it's a much slower process in water, but even in water, the stockholder slowly starts to dissolve after 5 weeks. so this bio plastic is not completely waterproof. sure. hope depending on where it's used, that could be a problem. i wouldn't recommend using fluid solid, say 4 chairs or area paneling, but there are plenty of applications that involve no direct contact with water. then it's excellent. you can compare it to untreated would not to help. fluid solids has already produced several other prototypes, including a tv data bothers us, be sticks, and decorative stars, water solubility isn't an issue with these products. but the big breakthrough is yet to come via plastic looks set to take off in the near future. these boxes contain product designs developed with major food companies and furniture makers
9:43 am
until they're actually ready for market. they have to remain top secret. beyond this, it can be exhausting. i remember firstly, it might help us grow the business if we were allowed to say with whom we are working on these projects. crawford. and secondly, i get people saying to me, we will have a be with you anymore because you keep saying that it's all secret of making readily degradable bio plastics from waste is certainly a compelling idea whether large scale manufacturers will also make use of it remains to be seen by degradable plastic should help solve one environmental problem. we asked you what other environmental issues do you think scientists should research and what are our biggest environmental problems? one shot from nigeria wrote for us in africa, science should focus on 2 things,
9:44 am
waste, disposal, and forest fires. we didn't have many large companies, so the global warming caused by these companies isn't the problem of making. ah, daniel, overwrought. i believe that science and she focused on waste water treatment and on technologies that can capture the store and treat c o 2. now we move some, a saw where says that scientists should investigate the causes of the plans that are destroying so many areas ah, pushing the hon. one scientists to focus on renewable and affordable energy, perhaps from hydrogen which could replace fossil fuels. thanks for your comments. this week's question also touches on an environmental problem. traffic analysis is leads to congestion and harmful emissions. arrived from lee had
9:45 am
a question about the how does living close to major roadways impact people's long term health. some studies suggest that living close to busy traffic on teresa cross roads is quite deadly. particular nitrogen, outside ozone, noise. all these factors increase the risk as heart attack, stroke, asthma, diabetes, cancer dementia, depression and allergies ah, the risks to health a directly proportional to proximity of toxins and noise. a long study conducted among 5400 post menopausal women in san diego, shows that the women who lived 100 meters from a major roadway were twice as likely to suffer from hypertension as women who lived
9:46 am
5 kilometers from a major roadway. the, however, the precise cause is that the increased likelihood of health problems isn't entirely clear. some research tends to focus on noise factors, other research on air quality. pollution, for example, causes approximately $8800000.00 premature deaths worldwide a year, according to a study conducted at the university of mines and the max planck institute for chemistry. but how exactly is the permit you just defined a day, a month, a year? research is calculated that the effects of abolition shows in people's lives in europe by an average of one year. recent studies also say people who have been exposed to particulate matter for extended periods of time and more likely to die when inspected by cars at 19. basically live close to busy roads is bad for
9:47 am
us and anyone who can avoid it shows me if i will let is read why i do you have a question you'd like us to send it in as a video text to voicemail feature on the show you'll get a little surprise from us as a thank you. come on, just on the news, you can find more fascinating stories from the world of science on our website and on twitter. me around the world. we produce mountains of waste. much of it ends up in africa and asia, where people who west, who recycle as labor and a terrible condition and stuff as serious health effects. that's because a lot of the ways contains many hazardous materials. batteries are also testified
9:48 am
as hazardous waste. but researchers are looking for ways to make them more environmentally friendly. here at the switch, federal authorities for materials science and technology research. as i working on the battery of the future, they'll need to store more energy, have a longer life, be more cost effective, and more eco friendly than today's batteries. to do that, they're looking to improve the chemical composition of the battery. a battery always has a cathode and, and entered the positive and negative terminal. generally made of element human copper to cathode side of a lithium ion battery is coated with compound, such as nickel cobalt and manganese oxides. and the side with graphite in between. there's an ion exchange membrane called the separator. ready the caffeine and an ode kept strictly apart, each lying in its own conductive electrolyte. as the battery charges,
9:49 am
lithium ions are released from the coating of the cathode migrate through the separated to the entered and are stored in the graphite. as the battery discharges the islands migrate back to the cathode to produce electrical energy, the electron flow between the 2 ends via an external circuit course in but talia and his fellow researches want to optimize these lithium ion batteries. over the past 20 years, the amount of cobalt in batteries has already been reduced. cobalt is a critical raw material and they want to cut it even more cobalt has in a properties that make it ideal for boosting energy density and battery life. that's what makes it so indispensable and difficult to replace with an equally effective alternative but industry is looking for alternatives.
9:50 am
ah, china has already invested at least $60000000000.00 in the electric car sector. europe as being slow off the mark up and it took the europeans, used to wake up and see this new trend on the horizon. now we're fast followers, which means we 1st need to catch up on the expertise that asia has built up over the course of many years. in the meantime, europe a set up a range of research initiatives. so about 10 years from now, we should be able to assume a leading role in the battery sector. battery market. the european battery alliance currently support some 70 different research project, including at the switched materials science research facility. it's experts are also testing alternative electrolyte materials with a high lithium conduction, right? they've already succeeded in the bar tree. instead of the conventional electrolyte
9:51 am
liquid, they use a lightweight solid version as the lithium conductor. that makes the battery lighter and safer. it's the liquid that makes lithium ion batteries hazardous. finally, there are safety benefit shuttles, but we also hope it will make them charge faster a lot, and then it would be okay for them to get warmer batteries out as a global undertaking to make him ability fit for the future, making it placer cleaner and more sustainable and the research is here determined to make that a reality eco friendly battery would have huge environmental benefits. last year they were some 11000000 registered electric vehicles worldwide, and new records, and 50 times the number just 9 years ago. the piston ration e cause will seen reach the end of their last spend. what will happen for all those
9:52 am
dead battery here and this former factory in berlin, a startup is found a solution to cut the overall carbon footprint of car batteries. i know her niche and his team give them a 2nd life. as the company's name suggests, they call them beggars. he's gotten the balance on the bus. when we get the batteries, the storage capacity is down to 70 percent. first we dismantle them, and we take the $48.00 modules out and analyze them. then we use them to build a new better packs. so the old battery still have about 70 percent of their original capacity and are far from spent. there just meant to check and reassembled, the old battery package up, cycled into a better pack, a compact 35 key, low energy storage module, reborn power back that also benefits the environment. so get to this is our product
9:53 am
vital energy supply system. this is tim. why are we doing because it is we want to help prevent c o 2 emissions and this is clean energy, the energy the powers climate agreement commit. nations to cutting c o 2 emissions to 0 by 2050, better pass could contribute towards that goal. they offer a clean alternative as an energy supply and for mobility to better fit comfortably into a truck. a 2nd lie for old car batteries. it's especially practical for parts of africa and asia as a handy option for clean mobility. i know whom it was once a managing director, ed rose rose germany not only is pursuing a green agenda and he's looking for partners to get on board at this
9:54 am
facility outside powers. his idea is going to be wrapped up in europe's 1st factory dedicated to recycling cars. automaker they know is eager to lead the way in sustainable mobility and is already set up joint ventures with start ups like batteries, family seem to fly as it only magic. we want to make our facility a pioneer because we're also convinced of the economic benefit to cos bulletin, movies, turner. this is a future of the automotive sector, meeting the demands of society and customers, climate and environmentally friendly evolution. committed by example. it's already paying these for shipping containers are packed to the brim with $54.00 repurposed e car batteries. they're stuck in groups of 6, forming a miniature power plant connected to the electricity grid. they serve as
9:55 am
a buffer to compensate for power fluctuations in the grid. the foot containers together can supply $8800.00 households with electricity for one hour on the banks of the river sand. in paris, the former car batteries have taken to the water d spot runs a tour boat company and was quick to get them on board. ah, so be sure to do the future for everything connected with the transportation. both the 2, especially even all the criticism about their environmental pollution. ah, but is refitting his entire fleet with the revamped batteries. they already powered his smaller boats with enough capacity for 2 trips a day. he wants almost all his both running on electric power in time for the paris olympics in 2024 and supplied by seconds live car.
9:56 am
batteries that for today will be back next week with another exciting addition of tomorrow today. until then by, by the the me, the news, the news
9:57 am
the news, the news the ah, we shoot the easier for just a traitor. julian assumes the price, the two's once in hiding then arrested. but he continued to fight. a film team has been following him closely for 10 years in 75 minutes on w. every day counts for us and for our
9:58 am
planet. the global ideas is on its way to bring you more conservation. how do we make, or how can we protect habits? what to do with them all our ways we can make a difference by choosing smartness solutions. overstaying said in our way the global ideas. mental theories included 3000 on the d. w online. ah, me. me, i cannot. because you
9:59 am
owe me. no, no, no, the i i use
10:00 am
a w need live from berlin you way for under fire is the euros appear to fuel rise and covert infections. world health, organization, official sites, social distancing rules have been forgotten, not just inside stadiums, but outside to after the tournaments. will the continent wake up to a huge koran of ours hang over also coming up.
