11:30 pm
you, these places in your 1st record gets into a globe. adventure is the treasure map for modern globetrotters. discover some of us record breaking on your into and know also in book form the o romantic and mysterious moon and have long captured our imagination. who is a western habitat in which became sant biomass becomes piqued that makes them excellent carbon things and also the focus of a great deal of environmental research. ah, all that's coming up a welcome to tomorrow.
11:31 pm
today you're saying sion. d, w forest is covered 10 times as much land area but moves catch store more carbon dioxide. that's in tax moreland, extremely important in the battle against climate change. the over the centuries have been drained for farming. some 15 percent of the world must have been drained and that releases large amounts of greenhouse gases into the atmosphere. some regions of particularly effective, such as the european union, russia, and indonesia. today's conforming move ends up being restored to restoring their better taishan. these inconspicuous looking moreland plans are under observation about the clock, an electronic scan. it takes meetings once an hour, talking that height,
11:32 pm
as well as the size and angle of their lead. these researches at the university of christ and northeast in germany, used to judge how well the clans to growing at varying water, a nutrient levels in their work. also involved scanning the rates in the 100 path longer, these means more pete could be home crucial parameters when determining the best way to re wet. the 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 more work? and what we wanted to see is a system where carbon is retained in the soil long term. and this set up, combined with field studies, allows us to investigate those questions. really convenient to try that. that's why
11:33 pm
we bring together the heat and the plants and the greenhouse gas flow type of food . or providing insights that will be a concrete help and future land management of to have good the water level, nutrient content, and range of plants all play a role in a more ecosystem. the wrong combination could mean a re, west is more ends up producing too much methane, 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 a re wetted mall tendons of why to choice and options to the store comes from lakes streams and rivers and his rich and nutrients. the common read also it's used as a fucking material for read. why does fit insulation fire proofing?
11:34 pm
ah, reach can i re graph and the common read potential buyer fuels in pilot form replacing oil and gas. so rubbing them on the west is more than twice the climate benefits animal. florida can also be great for water. buffalo, for example. all this means that wet funding off many opportunities for sustainable farming. but it's a different story on upland moles favorite lie only on vain motor duty and content, it's very low. so which france might thrive here? that's another question. the research is from the university of great folks on investigating the spectrum piece most is very much at home. many stream conditions offered by upland mold and criminal here on a large scale flight really payoff and conduction venue. allison has even asked me,
11:35 pm
you include in germany, we use around 7 or 8000000 cubic meters of pete a year for horticultural, some strength i soils that that's what most of the vegetables me buy in supermarkets are grown on just like ornamental planet. what have you, not shannon provider, 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 the top. more than using stock number replace to pete will only work if the scientists can breed fast growing variety. 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,
11:36 pm
norway and finland. data godek, teens perform regular checks 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 mos me. spec, no more fears, grow year round and ready for harvest. after 3 years care on experiments will fields, the researches are still using a converted speaker in the future. they hope harvesting machines will be able to go directly onto the fields. they'll know the spect namath, leaving the roots in the soil to give rise to a fresh generation of peep muff. way the field was seated off to harvest
11:37 pm
spectrum. it's not just useful. it can also be used in everything from insulation to diapers and packaging. it's a most versatile material ah, so farming on re wet, it moves to thrive. it will need to same kind of government support that conventional agriculture enjoy. germany 100000 pictures of land that is suited to growing spot in the most. it's a sustainable climate friendly form of farming with lots of potential for the future . ah, some of the plans that are grown on our fields don't end up on our plates. instead,
11:38 pm
they used to produce bio plastics for disposable dish where for example, but can such as cone and soy are important crops that help feed the world. so using cornstarch, 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 food creating bio plastics from waste. that's the mission of fluid solids in zurich. the materials that arrived here would normally end up and waste disposal like the boat husks that have come from a mill. so how can they be used to make plastic? because that's the 1st quick inspect shows the, the suitable spat casa, says, a wide range of natural waste materials can be used to any cellulose
11:39 pm
base materials caught her role, hammock coffee grounds grew as grain would powerful. we've tried more than 50 different things for the car began experimenting 10 years ago and also got an out as an industrial design. and so i'm curious by nature and like to try things out and we took the potatoes peeled them, and extracted the starch. we tried not show which we ground we've really been very hands on from doing basic research. and what are nice think lea a big kitchen, the goal of africa. at some point they came up with a solid material and the very 1st prototype was born back cause i used it to develop his own bio plastic. what is known as a composite 1st, the oat has the ground and mixed with 2 other components. mixing in
11:40 pm
by chemist francesca cheney a binder and a secret ingredient. go into the ground husks. this sample is still to running trial and error is still part of lab life here. yes. and i found the from open, you know, we have to optimize the manager to produce plastic material, which we can then process like regular plastic light in the normal stuff. and this is what it looks like when the mixture has solidified. it forms the granular the proportions need to be adjusted for each natural fiber. the 2 inventors illustrate this with their debut product soc hangers, theater the these ones, the very elastic. these once year though, you can definitely feel this difference in fluid solids produces hundreds of
11:41 pm
thousands of stock hangers in competition with conventional cheap plastic. the plastic market is highly competitive. impact. it's brutal decision. i fish all till we move in chuck interested water. ok, maybe that sounds a bit too negative. we 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 your ground against your competitors. that will happen on the team members demonstrate just how well the soc hangers, decompose using compost soil once buried in the compost, the bio plastic, the grades in 5 weeks. the
11:42 pm
much slower process in water. but even in water, the colder slowly starts to dissolve after 5 weeks. so this via plastic is not completely waterproof. sure, yet depending on where it's used, that could be a problem because i wouldn't recommend using fluid solid to say 4 chairs, original theory 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 the health fluid sol 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
11:43 pm
companies and furniture makers until they're actually ready for market. they have to remain top secret for ya. if it can be exhausting. firstly, it might help us grow the business if we were allowed to say with whom we are working on these projects. mclamery 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 biodegradable plastic should help solve one environmental problem. we asked you what other environmental issues do you think scientist should research and what are our biggest environmental problems. shown from nigeria wrote for us in africa,
11:44 pm
science should focus on 2 things, waste disposal and forrest bias. we didn't have many knowledge companies, so the global warming caused by these companies is a problem of making, ah, can you believe that science should focus on wastewater treatment and technologies that can capture the store and treat c o 2? now we move some, a saw where it says that scientists should investigate the causes of the plots that are destroying so many areas. ah, the grid yano stood at home when 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. moto right from allay had
11:45 pm
a question about that. how does living close to major roadways impact people's long term health? some studies suggest that living close to busy traffic on teresa crossroads is quite deadly. particular master nitrogen outside ozone, noise. all these factors increase the risk of heart attack, stroke, asthma, diabetes, cancer dementia, depression and allergies. on the risk to health directly proportional to proximity just full of toxins and noise along 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
11:46 pm
5 kilometers from a major roadway. ah, 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 death worldwide a year, according to a study conducted at the university of mind and the max planck institute for chemistry. but how exactly is it permit, you're just defined a day, a month, a year? research is calculated that the effects of abolition shorten people's lives in europe by an average of one year. recent studies also say people have been exposed to particulate matter for extended periods of time, a more likely to die when infected by cars at 19 basically living close to busy
11:47 pm
roads. it's bad for us. and anyone who can avoid it showed me if i was let is read, why do you have the science? cuz you'd like us to send it in as a video text to voicemail. if we featured on the show, you'll get a little surprise from us as a thank you. come on up just on the news. you can find more fascinating stories from the world of science on our website. and on twitter, the news around the world we produce mountains of much of it ends up in africa and asia, where people who are who recycle labor under terrible conditions and suffer serious health effects. that's because a lot of us contains many hazardous materials. batteries are also testified as
11:48 pm
hazardous waste, but researchers are looking for ways to make them more environmentally friendly. here at the swiss, federal, a bar trees for material science and technology research is working on the battery of the future. so 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 cafe and i kept strictly apart, each lying in its own conductive electrolyte. as the battery charges,
11:49 pm
lithium ions are released from the coating of the cathode migrate through the separated to the energy and are stored in the graphite. as the battery discharges, the ions migrate back to the cafeteria to produce electrical energy. electrons flow between the 2 ends via an external circuit course in but talia and its 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 been 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 alternative
11:50 pm
use. china has already invested at least $60000000000.00 in the electric car sector. europe has been slower, mark thought 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 as well. 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 projects, including at the twist 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
11:51 pm
liquid, they use a lightweight solid version as the lithium conductor. that makes the battery lighter and safer. it's liquid that makes lithium ion batteries hazardous. that is fine. i think there are safety benefits, but we also hope it will make them charge faster a lot and then it would be okay for them to get warm. and i'm of our batteries are part of a global undertaking to make a mobility fit for the future, making it place cleaner and more sustainable. and the research is here determined to make that a reality given the copy because brings the batteries that have heated environmental benefit. last year they were some 11000000 registered electric vehicles. world was a new record. and 50 times the number just 9 years ago. the person ration e cause will seen reached the end of their last what will happen to all those dead
11:52 pm
batteries? here in this former factory and 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 gregory's. so can the bones only, but when we get the batteries, they storage capacity is down to 70 percent. first, we dismantle them. then 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. dismantled checked 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 this,
11:53 pm
this is our product vital energy supply system. this is tim. why are we doing this? it is, we want to help prevent c o 2 emissions and this is clean energy, the energy the powers climate agreement to commit signatory 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. second lie for old car batteries. it's especially practical for parts of africa and asia as a handy option for clean mobility. i know her name was once a managing director, ed rolls royce, germany not only is pursuing a green agenda and he's looking for partners to get on board at this
11:54 pm
facility outside paris. 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. well, the family seem to fly as it only magic. we want to make our facility a pioneer because they're also convinced of the economic benefit to cost hospital movies. turner, this is the future of the automotive sector, meeting the demands of society and customers, climate and environmentally friendly. lucian's was strictly metric by example. it's already paying off. these for shipping containers are packed to the brim with 54 repurposed e car. batteries. they're stamped in groups of 6, forming a miniature power plant connected to the electricity grid. they serve as
11:55 pm
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 stand in paris. the former car batteries have taken to the water d. d s spot runs a tour boat company and was quick to get them on board. ah, to be sure to do the future for everything connected with transportation. both the 2, especially, even all the criticism about their environmental pollution. ah, but is refilling his entire week with the revamped batteries. they already powered his smaller boats with enough to pass city for 2 trips a day. he wants almost all his boats running on electric power in time to the paris olympics in 2024. the supplied by seconds live car
11:56 pm
batteries for today will be back next week with another exciting addition of tomorrow today. until then by by the ah, the news? the news? the news,
11:57 pm
the the the me ah, the thing like a great to see and to come the so ah, it is an island as early as germany's longest speech, some 1900 hours of sunshine a year. the charm of a bygone era on the medical baltic sea island of louisa. don't lose trick in coming up on d w. the koran
11:58 pm
sis ah ah ah ah 2030 minutes dw, lose . can you hear me now? is germans house. we bring you uncle michael and you've never had had before. right . just so with what is who is medical really want me and also talk to people who follow along the way,
11:59 pm
admirers and critics alike. and how is the world's most powerful woman shaking her leg? is be joining us for macros class. in december, 2019 the european counties president show me shows embarked on a ground breaking mission. i have a job to make sure of the 1st time a gentleman on the planet by 2050 but not all member states supported and some persuasion is required. a surprise he glanced into the very heart of power. negotiations. money use money can be the process. flattery and the best laid plans often go straight the most of
