the battle for freedom and dignity. against repression and violence they deplore the powers of social. the messages are spreading like wildfire and thousands of followers are joining the last. album on the streets. changing the. digital. starts marching on w. . the search for a sustainable role materials for use in industrial production and processing is intensifying. we can use this material to manufacture any number of different products saving a huge amount of petroleum based plastics. germany's eco innovators are prepared to
travel to the most remote corners of the earth in their hunt for new sustainable resources. might come almost anything made from the many a more steel can be made out of bamboo these pioneers want to put the brakes on over exploitation of natural resources especially fossil fuels and their derivatives what is the original limit at some point we're already over exploring the planet the search for alternative raw materials is becoming ever more urgent. chicory is one alternative raw material with great potential its leaves are usually atan but the pioneers are also. so interested in its roots they usually end up as
waste or as sent to the bio gas plant. professor andrea cruiser from the university of pool on high and uses these chicory roads they contain a substance that she needs for her research. well this is the bit you eat the vegetable but we want these roots here they contain a storage substance that we can use to make a platform chemical. in other words we can make stockings for example or beverage bottles out of these rates thank you for asking my. chicory roots are too bitter to be edible apart from fermenting by i guess there is little else you can do with them that makes them ideal for andrea cruz and her project. this is the first time we've been able to produce this platform chemical from
chicory beets or any kind of waste product. that's what makes it special the chemical is called hydroxy methyl for all it's commercially available but then it's made from sugar and the production process is rather dirty so we have a clean process using something that is not a food and that's important to us. in her bar a tree at the university of hall and time cruisers spent more than five years searching for the right role materials chicory is ideal because a substance forms in the root from which they can extract a basic chemical building block simply by boiling it. the chemical is used to obtain additional substances and at the end of the process you have nylon.
cruiser believes this could be a real alternative to petroleum based plastics. five hundred thousand tons of chicory waste a produced every year in europe alone enough for about three billion pantyhose is this it again we know that oil is limited in other words it will run out at some point. and of course we also have the c o two problem. when we use crude oil we also burn it in some form to break it down so to speak so that produces carbon dioxide. by that it's the odd and also special thing is when you use biomass it also releases c o two but only as much as the plants absorb while they grow. cruiser hopes that one day plastics will be made from chicory
roots though she will need more funding to make her project marketable ideas like hers are urgently needed says ben human buckhart materials expert from the environmental association nabu. here are your hat on the neck and we've all seen it . we've all seen news reports of explosions on oil rigs or tankers transporting crude oil on. these kinds of things do catastrophic damage to the environment off oil is a very problematic raw material. or the extraction causes problems. and even more than that the refining process is very energy intensive mandamus a lot of harmful gases it can be a threat to health. and being one declining going touch at least. in addition the global population is growing and placing ever greater demands on resources including crude oil usually unless now believes that coffee may be part
of the solution. twenty million tons of old coffee grounds end up as waste in germany every day like here in cafes. yulian less now is testing methods to turn these coffee grounds into an alternative to oil based plastics. the used coffee grounds have to be dried. misspent more than a year experimenting with avon's used for baking or drying fruit. he's also started having larger quantities tried industrially. after drying the grounds look like regular coffee again. in fact the coffee brewing process is the first step in lessness production method as at the hottest it turns out the coffee
that has been brutal ready in a cafe or in your kitchen is better suited to production processes. and coffee contains quite a lot of oils those oils are flushed out when coffee is brewed are pressed the less oil the coffee grounds contain the better it is for the production process. and it will be shared and it's going to play nice. the old coffee grounds a mixed with cellulose wood and starch to form a granular it just. it has the same properties as petroleum based plastics and can be molded into different shapes. dishware for instance this cup and it's also contains about sixty grams of coffee grounds. less now runs his marketing and sales operation out of the social workshop the
product designer believes coffee grounds could be an important new material of the future. ethylene is their coffee the coffee grounds in this hard form could replace traditional plastics. which we can we can use machines that normally process plastics to create my products to. what i've made here could serve as an alternative to a massive amount of petroleum based plastics. coffee is a consumer product that is the second most traded product in the world and there's enough coffee available which in turn could replace quite a lot of other raw materials for and then be turned into new products. so more important and far better. left now is designing other products to the cops were just a beginning his next idea is a substitute for regular paper to go karts. he has to go caps
a made out of an organic material that is recyclable biodegradable within a few months dishwasher safe and almost unbreakable. baristas wouldn't have to keep replacing the porcelain and at home you could wash the cop outs and keep using it right or thing. coffee ground plastic turns out to be very versatile this skate board was also made out of it now has a lot of ideas for new products buttons garbage cans building materials and. the technical university of braunschweig is also conducting research on new roma tiriel on a grand scale. one focus of investigation is the mineral oil free
factory institute director christoph hermann is trying to find alternatives that can replace oils in large industrial machines. that it is not are that we're looking for alternatives of course fossil based raw materials including mineral oil are a finite resource mineral extraction also results in a series of environmental impacts that extend across the entire cycle from extraction to processing into mineral oil so it would be a major step forward if we could find substitutes that have a significantly lower environmental impact because the rest of. this machine is being used to test for cooling live a trend for milling machines it looks like water but is designed to lubricate remove metal particles and serve as a coolant lubricants like this a usually based on conventional crude oil in twenty sixteen sixty eight thousand tons of oil we used to manufacture cooling lubricants in germany alone.
pioneers like christoph herman and looking for natural alternatives that have properties similar to oil. be discovered one day weekend in the animal kingdom. spitting on the side what actually happens to all those crab shells. people consume huge quantities of crowds. so if you're wondering what the raw material looks like you actually already know. when you order a big seafood plate you end up with crab legs like this. from the king crab. and this shell which you can't eat is waste that it can be processed into a natural polymer called cotton cutters or which is water soluble and can be used as an additive goodness that got. in the crab based additive is tested for its
lubricating qualities in a glycerin water solution to see if it might be suitable for industrial use. one day a product like this might replace hydraulic oil. researches are also searching for metal alternatives it's an urgent task says materials researcher benjamin hart traditional steel and metal production consumes a great deal of energy and poses both a social and environmental burden. and if you're an author and i think you want one regions where metals are mined often become conflict regions so these countries also face ecological conflicts because ecosystems are being destroyed i and of course the profits from that also don't always go to the people who are entitled to. be in the eye gets water.
steel and iron are produced after the war was which had been mined hearing central germany's hearts mountains for thousands of years geologist retard kanada has been studying the consequences of all mining in the region for decades. although the local metals industry is long gone the scars remain lead zinc and copper woman. until the one thousand nine hundred. eleven skype is still dotted with slag capes and toxic mining weist. as. there is no such thing as sustainable mining when you intervene in nature like this it's never sustainable mining doesn't just remove soil it removes forest and bedrock too it does permanent damage and destroys the natural environment. it's something your ordinary tourists will never get to see when they visit
a historical mine i know this is stored. in the later mr field the metals from the huts mountains were used in many major industries to camilla the impact of mining is further proof of the importance of finding alternatives. we have to pursue any idea no matter how our land is for replacing a dryer mentally damaging raw materials in. this soil here is contaminated with heavy metals even the trees that were planted after the mine shot aren't growing properly the mines also affected the ground water this artificial lake is also contaminated with heavy metals for local residents it's a significant health burden for you are in the past when there was a dry summer's day of them are dried and was blown about in the when you get in your mouth and the heavy metals would crunch between your teeth. and you can imagine how the women used to complain. they wrote letters to the editors saying my
laundry turns black and i can't get a clean i have to wash things two or three times because of the dust clouds blowing off this dangerous waste landfill. of high today we have two choices. either we leave this waste where it is and secure it properly. or we reprocess it using modern recycling methods. the waste contains high levels of lead zinc copper cadmium indium and other metals that could be recycled and then retire and when demanded of your income canelo regularly take samples of the contaminated water it's his job to monitor the pollution that the entire region has been able to contend with. here in kill a roll material that could replace aluminum steel or carbon in the future is
already rolling through the city center are. going to start is a pioneer in metal alternatives. is by fracking is made of bamboo. as was a great about bamboo is that it makes for a very comfortable right at the bamboo consists of long fibers which absorbs shock that's really nice when you're writing over cobblestones or bumpy ground like i was unless i'm going to miss fire three. he's sold about a thousand bamboo bikes since he founded his company four years ago. the bikes are assembled in kiel city and touring bikes and now and he bike to. the frames are made of bamboo most of the other components
a missile. on which they and i. buy school frames are usually made of steel al-ameen your more carbon fiber those are finite materials and their production process also consumes a great deal of energy. using a bamboo frame offers a lot of ecological benefits it's a raw material that grows very quickly in the wild bamboo grows faster than almost any other plant in the world and in vast quantities so we take this role material from nature and then we build the frame by hand which also conserve energy it still needs the same technical specifications as a frame made from a conventional roll material but uses a minimum of energy. the bamboo for the past sickles comes from ghana. together with his workshop manager stuart's good travels to africa several times a year he first discovered band in twenty twelve since then he's been collaborating
with a local workshop. the bamboo is harvested in a remote town of just thousand residents. here in this workshop bamboo components are prepared for customers around the world it's the largest workshop for bamboo classical in africa. because bicycle friends of mine here. he comes here every few months to observe the work and brings new tools with him. as with a normal bicycle the bamboo chips come in various with skimpy classes. ones
in here this chub is relatively thin with a relatively thin outer wall we use this for the top tube because it doesn't have to withstand as much force then here on the other side we have the lower tubes which are much weaker the outer wall is thicker so it's sturdier. as a natural roll material than do is not as uniform a steel bar most of the plant can still be used. against gaza but we use large bamboo plants about twenty to twenty five meters tall one single plant has all sorts of thicknesses and diameters we cut up the plant and then categorize it according to thickness so we use the entire plant. if some don't most harvest time while the bamboo grows in the area surrounding the workshop. any.
of the bamboo has a very hard surface and fake outer walls making it a perfect substitute for metal the workers come from the area off because bicycle factory has created thirty five jobs c.f. looks set to become a material of the future once manufacture is back in europe to catch on. was more than a modest of it but aren't completely uniform on it's a natural raw material so production processes are more complex than with aluminum or steel using bamboo costs more at the moment but other resources are finite so will eventually be forced to make the switch to renewable materials bamboo will be a very big part of that but one of the. bamboo grows very quickly it doesn't take up much space and it doesn't need much tending and it requires no pesticides.
and is in here when this right here is almost a bamboo tree a big cluster of them is growing wild to hear the holding of oxygen. in just two or three years a tiny bamboo shooter can grow to withstand thirteen meters tall. i mean what we can make five to seven bicycle friends out of once them so that's a lot of them against a man or. a few. feet from the bamboo stands a dried that's how they lose their green color. then temperate says sultan recycled industrial adhesive a product for which there is no natural alternative yet. keep using the glue so drop the bamboo in metal parts a join together. that it. was in.
when there dried the hardened temp joints a sanded by hand and then foundation. a single bamboo frame replaces about two kilos of steel. the finished parts of a ship to kill in ritual fluid close to about fifty people. straight and germany go into a bamboo bicycle in germany they cost upwards of fifteen hundred euros. for like any bicycle made of steel carbon fiber aluminum the bamboo bikes also have to pass stress tests. but customers i'm most concerned about a juror ability many is still wary of the new rule material.
if you can find the hero of almost any customers wonder whether bamboo we spared enough but with put about a thousand bikes in the road and still haven't had any frame breakage. the surface of the bamboo is extremely hard and there's exterior organs on the distance fish. the keel startup has created a market for its products without help from outside sponsors or funding. the climate center in the northwest german town of their helps fill that gap. they provide a network for entrepreneurs and give them access to technology like three d. printing for example. to help spur innovation direct to mari louisa rotman maya brings bio economists and project managers together fibers made of papers all pieces for example are already being used to make three d.
printed products but there's still work to be done. bennett is a hint at a number of german associations are very committed to this idea but in the netherlands for example they have a kind of credit system to reward products with a positive environmental impact or something like that here could help boost the market or we could support baseline production quantities that would really help pave the way for these products. but this kind of political support isn't on the radar yet in germany. the german ministry of research does have a few prototypes on hand and offers many funding programs but it's a bureaucratic operation that's anything but hands on. deserves to.
this topic is a bit abstract for ordinary citizens who have never had anything to do with bio economics. or didn't drink and. we hope to support this work in the future by offering agenda processes and conference programs they are made of birch bark not plastic. if there's a mission in and we don't just want to use renewable materials for our frames we want as many of the other components to be made out of high quality renewable materials as possible and. birch bark was a popular role material hundreds of years ago until it was replaced by plastic a new generation of entrepreneurs are trying to bring these natural materials back on the market as quickly as possible.
