the environment is not responsible make up your own mind, dw, made for mines, the how can commercial trucking help protect and sign? it sounds crazy, but switzerland is trying a new approach to the greenhouse gas problem. it's collecting carbon dioxide produced by with industry and shipping. it to thousands of kilometers to iceland their, the gas is pumped into the ground where it's trapped and turns into a solid future technologies for a cleaner environment. this time on dw science. so welcome to tomorrow. today a very special tank is waiting a positive freight station. it's been pumped full of c o 2 from switzerland that's

being sent abroad. a pretty unusual load for the driver this distance. so you don't transport c o 2 every day. and this way i can do something good for the climate to this. we truck drivers are often seen as major polluter and so forth by transporting c o 2 we can show we're not so bad after all in switzerland to ship the gas a special permit is required. that seal dog c o 2 is partly responsible for climate change. this tank of it is being taken to iceland via rotterdam in the netherlands. it's a pilot project. it's one of the 1st c o 2 transport emissions

in europe. the journey starts at this bio gas plant and burn it produces almost fewer a carbon dioxide around $6000.00 tons of annual light process engineer and professor michael much salty, has spent years studying c o 2 capture. today we meet about $40000000.00, which is due per year and the plans are the climate strategy of the, of the, of the food is that we reduce emissions by electrification to about $10000000.00 toasts. but here in 2015. so in 2050 we will have to handle to manage 10000000 tons of c o 2 from us resubmit this, these are the so called higher the to a bait. that means shows filters are now installed and the plants chimney stacked to capture the gas. it's then liquefied and cooled to minus 20 degrees celsius for transport. sensors for

a container like the one we saw could only transport around 40 kilograms of c, o. 2 in gaseous form, and that's not enough. but if we liquefy it, it takes up much less space and we can transport around 20 tons for a container. the liquid gas is under high pressure, so it has to be handled with care. the leak could be fatal. it is on teens. madison has been just as soon as anyone who is close by could get sick, who's become disoriented or simply pass out and they have to go to things got really bad and they might suffocate. understood. and off we go. setting out on an over 2600 kilometer trip to iceland. the bio gas plant admits this much carbon dioxide in just over a day to become c o. 2 neutral by 2050 switzerland would have to organize 500000 such journeys every year. the project was born at this with the

federal institute of technology into wreck. the results of years of research directed by michael much not the greenhouse gas has to be exported because there's currently no suitable storage facility. it's west territory, 3 equals one until the single dose. one point to my personal opinion is that even if you find sites in switzerland, we need anyways, more capacity. and we will have to go to combine storage in switzerland and storage abroad. an ecological assessment of the transport process is positive. we have made an evaluation of this, that was one of the main goals of the demo karma. and just seen that we can, let's say you have an efficiency around 80 percent in the whole the chain transporting system from switzerland to iceland. a cement factory in paisley,

not far from burn production of the material is energy intensive venom its large amounts of c. o 2 hopes are high here. that exporting the gas could lower the plants, environmental impact the to be sack, all those on demand by 2015 swift concrete producers will have to store $2000000.00 tons of c o. 2. keep up with making concrete, without those emissions is impossible. it'd be separate yourselves that got so it makes sense to filter out the gas directly in the chimney stag. see what there's on . that's much easier than removing it from the atmosphere later. it won't accept julie optic who died iceland. 13 days have passed since the trip began in switzerland. the container has finally reached the port in the capital. they can pick iceland hopes to act as a sing for huge quantities of carbon dioxide from all over europe.

below the surface, the volcanic island is 90 percent by salt rock highly suitable for this purpose. the last steps of a long journey take the container south west of the thanksgiving just 50, more kilometers before the c o. 2 is finally pumped into the ground. upon arrival of the liquefied gas is 1st emptied into a tank, then injected into the ground under high pressure. the process is straightforward. so what we see here is the injection. so it's 400 meters inches. so then we have a see what the gas, which is something in co injected into the best rough

when the gas reaches the sub surface, it solidifies and is trapped in the rock. here is what we would like to kind of display as a before and after before we have a very porous rock and then once we inject alicio to mentor lies, we have a more much more dense truck with the kind of whites back, which is the seo tool that has been monopolized. so the process of c o 2 minute recess and there's something that's not 3 occurs, but this process in nature sim, take up to a 1000 years. but what we're doing here is kind of speed things, same stuff. and it happens within the last, within 2 years. not everyone on the island is happy about using natural processes in this way. the environmental activists like handling them, your highness door theater, say the risks are too great. she believes every country should store its own c o 2 . actually i would say it's

a bad thing to get it from abroad because it wouldn't be pollution from the those big ships meet, don't like that because the font i sent this guy think like a trust trust ben foot been for other countries and it could be like small earthquakes, well, monday we're starting this up and had to say they, i mean we are trying to compare to that. they have to us clerks in between because of that. so i would say yes, it would be those in charge of the project say no, seismic effects have been observed so far and that no c o 2 has reached the surface . the iceland is expecting several dozen more containers filled with, with c o 2 suits and that's probably just the beginning,

the, the oceans absorber huge amounts of c o 2. even though we still don't know exactly how the process works to gain a better understanding of the sometimes bizarre life forms found far beneath the waves. researchers are investigating animals able to survive the extreme conditions in the deep sea. the one creature that's always good for a surprise, jelly fish, the science expedition off the island of madera, in the atlantic on the jelly web mission. an international research team is looking closely at the role that jelly fish play in the marine food well finds and testing is jelly fish are currently a hot topic and ocean research because for a long time, we've completely misunderstood how important they are to the system. we now know they're very important dispos predators and pray and also have much larger bio mass

as than we thought. and higher species diversity. he fired a diving robot that weighs several tons is being used to find out more about the animals. it has to function at depths of up to 2000 meters below the surface, under immense pressure. the teen steers the robot from the ship. it collects and brings the jelly fish to the surface, unharmed to get so many made out of it's a matter of millimeters during this giant device down there in such a way that the animal floats exactly into this small opening homes. what makes caps are even harder is that of course, we have all the thrusters for positioning. and using them generates flow of the money that can easily cause an animal to simply float out of range. again, your eyeball who to austin booth? always feel the we still have

very little data on the role of jelly fish in the deep sea. that team has found more than 50 species that have never before been detected off a day or uh, photos like these help answer questions like, who is eating? who, after almost a month on the chef, usually on shelf, are returns to the g. omar helm road center, and kia to evaluate the data. the doctoral candidate has nothing to see bad trying to find out which animals live, where one thing he observed on the expedition stood out across me. certainly said richard, what really amazed me personally was the human impacts and our data, even in the deep c as in dog. and we saw lots of loose fishing lines on the seabag, often and also garbage. so models and plastic option plastic the human induced climate crisis has also long since arrived in the deep sea because the ocean stored large amounts of c o 2 best outside of us. and then some of the c o 2 that's

absorbed by water on the surface has transported into the deep sea di funds. but we use the term biological carbon palm to describe it or so that describes fixing dissolved c o 2 and bringing it down to the c bed where it's stored for a long period of time. it was, i gonna type surprising how much carbon dioxide ends up there is also dependent on the food chains that on the gas. but there are still many unknowns as high as it is a teeth expedited. so i think this deep sea expedition is extremely important. i might because we still know so little about this environmental device and because it's a challenge to understand the data, what do you even have, what species, what diversity we have to determine that 1st of otherwise there's simply to greater risk will ruin things we don't even know about when the amount of products with the greenhouse

gases are also released when trashes incinerated, hospitals and clinics are among the biggest producers of waste worldwide. disposable items like single use gloves and masks, land and bins there. but also many more expensive surgical instruments and devices . something needs to change in a hospital in western germany is showing a found an abdominal exam at ponds university hospital. every day a wide range of medical procedures are carried out. and it's 40 operating theaters from appendectomies to tumor removal. that 1300 bed hospital is a care provider responsible for the health of many people. and for a lot of ways, we produce mountains of trash with single use materials alone. and it's not just surgical equipment, door disposable instruments, even complex. so electrical instruments like surgical staplers and ultra sonic

scissors are considered hospital waste. so they usually end up in the incinerator, phillip lingle and others who work on the surgical teams hate that germans are told to separate waste at home, but in the hospital everything's supposed to land in the garbage us. of course, we tried to reduce the amounts of waste as much as we can. another aspect is that disposable devices are sometimes significantly more expensive than we use simple ones. a device can cost between 5 and 600 euro. then after you use it once for an operation, it goes into bin, which just doesn't make sense. maybe not, but it's common practice. in fact, that's what the construction trade, commercial and mining industries. hospitals are the 5th largest producer of waste in germany. they turn up $4800000.00 tons of it per year. the hospital in pa,

now employees waste manager michelle schmidt. his job is to get waste volume and disposal costs under control. his methods are now being emulated by other clinics across the country. okay. the crowns the males. of course, our primary task is patient care and safety. however, waste volume has risen more and more in importance for a number of well documented reasons. he'd i'm the disposable of waste as climate. but disposal infrastructure hasn't grown with it. is this damage was myschoolbucks, and in order to establish a system of sustainable separation, schmitz realized that waste streams needed to be digit, alive to staff. now know exactly what waste is generated, where and report quickly when there are problems with separation or with disposal companies. you can also, and now we know our waste disposal and recycling streams at the hospital very well and tried to optimize them as much as possible. the good thing is that we not only

save resources but also lower costs. so currently the hospital is saving around $100000.00 euros a year instead of a 1000000 euro is it only spends 900001 disposal. that hamburg based start up for a source of fi has helped with special waste collection software in a room and the operating theatre wing, different colored bins have in place to collect waste that's particularly valuable and worth recycling the hospital and needing some challenges. the lack of space, you know, ours are planned in such a way that lots of technology fits but not 10 different recycling containers. so there has to be a central collection point where things can be disposed of separately. and talk then con aluminum, for example, is a valuable resource for staff. waste separation and the operating room is now routine,

less waste and hospitals. it means less than center ration. so lower c o 2 emissions worldwide. the health care sector is responsible for over 4 percent of all greenhouse gas emissions in germany. the industry spews out even more over 5 percent. saving, forestry, and hospital operations were ahead of heavy industry and the air traffic, which is fine years ago. we realize we have to change something. one focuses energy in 2018, we switched our heating system to thermal power plants. they produce all of our heat and steam, some of our refrigeration and 76 percent of our electricity in the school. most of the hospitals, goal is to be climate neutral by 2030, a more efficient use of anesthesia, n o, r is, would also help anesthetic gases, or among the worst climate pollutants world wide one called dest fluoride,

for example, is over $2500.00 times more harmful to the atmosphere than c o 2 i. so fluoride is over $500.00 times worse and sub flooring $130.00 times. but there are other gaseous anesthetics that do much less damage to the climate. the hospital in bon uses only those products and us spiritually as possible. and you can compare it to a car traveler. one dose of anesthetic is equivalent to a 20 kilometer trip in terms of the c o. 2 emissions or under on favorable conditions like high flow or the wrong anesthetic, an operation could be equivalent to a 900 kilometer trip. so it gives us a norm is potential for savings, and that's what we train for here. it means 200 tons, less c o 2 equivalent at the hospital for the 36000. and that's the ties. surgeries, we perform here every year. producing waste and the health care sector. long term

requires large initial investments, but it's worth it pretty much the expression it's rich environment protection always pays off because the costs this we incur. if we do nothing, it will be many times higher. we saw with the our river disaster. what kinds of costs are incurred and we'll all have to help pay them i can get and miss my son, cost an interest in climate neutral, modern medicine that can save resources. a goal for the entire health care sector in our clinics in our closet, in our supermarket, plastic consumption this on the rise everywhere. and most of it doesn't decompose in the ocean bottles made for me. it takes 450 years to break down into micro plastic. bringing the material is not a great solution either. it produces toxic emissions. problem is not all plastic is

the same and that makes recycling. it complicated. could it be made easier? the university in the german city of holes home to the institute where plastics, scientists, machine, nazzo, and lucas golf mind conducts their research. among other things to, to are working on compounds that are easier to recycle. plastics can be assembled from different chemical components as these magnetic building blocks are meant to demonstrate. one of them represents a molecule, a single hydrocarbon called a monomer, as a queen. so why is that the ex, or column, or is, are made up of monomers? so individual repeating units, i'm on, you know, if you link many monomers together, you have what's known as a polymer ends orthodontist. what do you mean? what are the name on the plastics also contain chemical additives, putting me on hold. so we can also attach additives to modify our polymers,

these can be plas to size, or as for example, i see these are usually quite faulty molecules attached to between the chain system . i'm not going in polyethylene, for example, the monomers are molecules that form long polymer chains. then the additives are attached. there are an estimated 13000 different additives to choose from. they give the plastic specific desire properties such as the last test the day. identity is currently alternatively we could also attach lubricated sub for reinforcement materials like a natural fibers. and that you could almost imagine would lie on top of the engine between the right time. we probably wouldn't use class to size or so let's get rid of the next year. it's all quite simple. i thought when it comes to recycling, it's not as easy to separate everything. we'd have to deal, for instance, with these reinforcing fibers that we added. the constructor stacking the 2

researchers are developing plastics that require few additives that makes recycling easier. so here's a add algae to a polymer made from lactic acid. both components are non toxic recyclable not made with fossil resources and even biodegradable c l g additive is designed to make the plastic green or but that isn't all like other additives but also changes the plastics properties. so this is in our plastic. the algae also plays the stabilizing role, so it makes our till more stable. that means it's more likely to have the properties we need for our application. and if we didn't use the algae like any science of singles, this extrude or uses heat to mix and fuse, the 2 components to material comes out of the machine is

a kind of plastic sausage after cooling and water fits chopped up into a granular after further development, it could be turned, for example, into food package. it is, even though that's difficult to manage, to be honest, there are now a lot of requirements involved in making food packaging films or lamb and upset to show why this is the case. the 2 researchers break down a typical example. packaging used for cheap yeah, and packaging like this is re c a level, but you also need what's called a water vapor barrier. usually polyethylene takes care of that. then you need an oxygen barrier and it's usually made by combining poly mit, ethylene vinyl alcohol. and these 2 layers are not compatible. so why also need

something to promote adhesion? that's why packaging can swiftly become up to 7 or even 11 layers sick because you see what does look like fish design. con. the biggest challenge when recycling is that waste is a mixture of many different plastics and additive researchers hope the new material made from just one polymer and the non toxic additive from spirulina. ology will solve this problem. ok, that's all okay. let's see if our spirit, lena power works 1st item next, they want to use it to produce a film. the problem is that because organic molecules are less stable, plastics made from them or more difficult to produce. the scientists therefore experiment with different temperatures and mixtures. that's the film comes out of the machine. lucas gloss. mine explains that plastics like this can always go wrong

. forcing them to start again. but if it, with stanz processing, it could be turned into a non toxic, fully recyclable packaging, not based on fossil resources. the next day we're trying out another mixture with a different composition. lucas kaufman adds more bio polymer. the film does through a bubbles, but it looks ok. we're positively surprised. it's so stable. the film remains intact. just one of many prototypes not yet suitable for packaging, but a step in the right direction. initial tests of process ability, fitness and 10 cycle strength are satisfactory. so far. the film could become an alternative to poorly recyclable plastics. the that's it for the show. this time around. thanks for watching and hope to see you

again soon on tomorrow today. bye for now. the on the
