timing and insulation and packaging that would reduce c o 2 emissions is that enough to make a natural result sustainable. it is not just about emitting less as. we also consider social criteria fair remuneration in the respective countries. or your regarding the agricultural context where does the maize come from from a land that is biologically high value with a lot of biodiversity or fields where old growth forests or rain forests used to be . the father criterion for sustainability is where the materials can be recycled most conventional plastics company p.t. from say bottles can be used. but much too much plastic waste and stop littering the environment slowly crumbling into ever smaller fragments. from micro plastics can be found in the soil just about everywhere they come from

a range of sources rubbish dumps and sewage sludge used as fertilizer on fields and we don't yet know what effect these particles have on the structure of soils or whether they expect to soil fertility worked. the spray on rape seed mulch by contrast eventually washes away at a predictable pace. as long as i'm up there on our materialist biodegradable plastic foil often soiled and contaminated with other chemicals and has to be disposed of or recycled with great care our material can stay out in the field. as it decomposes all that remains there are a few non toxic selves the to kyron they check anyway it's a home this product derived from nature. there's definitely a lot to consider before finding the well factor vollmer to substitute plastics but what if you want to look at existing supply and demand models. and find

a solution that big bang will make for example it has had a long tradition of job production and cultivation but today follows a producing excess joint and knocking all of it leaving behind a huge list a local scientist seems to have found the well fix solution to this problem. it looks like plastic it feels like plastic but it isn't it's a plant based product. part about you like you can make had these things you will get approved packaging materials that will be done or marketing material you could with the government by getting material it will be the. shopping bag single. khan has spent years coming up with a substitute for plastic the raw material he works with is jute from which he creates a water soluble base 40 he then adds

a natural starch based binding agent. most certainly in one part. and then we use some other chemicals i'm not mentioning this chemical because they're more secured part of this should be and then we get this. final. product which can then be made into a for oil now khan is hoping that his invention dubbed dishonestly will draw global interest. this is just one polypropylene you can see. morning if you could see produce that drop this is. the group that does it before the market. but turn it around this is my finale. you see there is no drop of plastic here just like paper see.

after a while ash is all that remains. this is a. land where probably more jute will be grown like here the plant is the number one natural fiber grown in bangladesh it's composed primarily of cellulose the main component in sauna. moslem bed party is one of 3000000 jute farmers in bangladesh what he's harvesting now he only sowed 4 months ago. the climate in bangladesh is ideal for growing this crop which requires plenty of water heat and humidity and editing to do. the jute fibers are found inside the stands and have to be separated from the rest of the plant. it's painstaking manual labor the whole family lends a hand. once again it's not been a good year for the pharma floodwaters washed away

a part of his crop and prices have dropped so he won't get as much for what he's managed to harvest. you have to borrow money just to make ends meet. buyers who there was i have no idea what will happen alternately this jeered and they tell me the government isn't buying much because demand from foreign markets is down so they don't offer us good prices but i have to sell it to them anyway. around 40000000 people in bangladesh make their living from jilt either directly or indirectly at the sauna project could change their lives but. at the moment it's still at the experimentation stage. the government is funding the pilot production at this factory. but this new machine will soon be producing a ton of so nearly a day. is that maybe somebody's going to come and go for

a whole or because it is a lot of. songs and. the juice industry is one of the biggest economic sectors in bangladesh. it's viewed as a kind of national treasure closely linked with the state's founding and for many years its only export many here hope could help breathe new life into the industry . the digital revolution and the big it has provided us with has given us a big push to be more and more environmentally friendly young people around the world leading this trend and i'm more aware and did know about it about protecting them. in the next. we met one such group of students that's the. 1000000 dollar limit livable is best achieved with the help of people who live here

. using new technology to contribute to a better understanding of traffic. i would like to see the city authorities and the general public taking care of the trees. these students are applying their coding and programming skills to the development of applications and devices to make cities more ecologically sustainable. it looks relaxed but they're actually taking part in an intensive summer school at city lab . the better ones have almost got held around us is full of technology and how it microcontrollers like this you can see how much of it both invisible and indispensable in our everyday life works really well here we want to make things with them ourselves. at various workshops during the 9

days of the summer school the participants develop all kinds of ideas and inventions all in a relaxed atmosphere outside of the classroom and the city lab is a venture that brings people in berlin together to work on sustainable or. been development. in the photos for months decides i like a summer school for massive we means outdoors in the fresh air and working pretty interesting technology and topics team yet so much we've got them on like you have some online lectures but now we're working together on group projects so when it's a misstep because everything has been remote since the coronavirus here now at long last we can work together again as the topics are interesting and something to. $54.00 students from 4 berlin universities took part in the summer school this year this online lecture by professor colony was about digitalisation and sustainability she says urban development processes need to be more inclusive. and days

to be made available to very different groups in society including people who don't have much experience with the internet who can't write computer programs how can they nonetheless access data and use it to develop something new and because. most of the workshop participants are studying business information systems and are already used to working with technology and computer programs. they relish the opportunity to brainstorm and work on innovative sustainable and eco friendly projects. yeah your line on when to compile it has no names on up on it i've used to solar panels and a lithium battery to build a device to charge a mobile phone i'm on small run a development board and a lot. of. inflicting spots let's see what even when there is no external source of electricity compared to way off grid. i think.

among the projects developed by the students at the summer school. a new system of hydroponics for city plants and a digital map of sustainability initiatives. to be deterred is your never numb time digitize ation wasn't considered to be very important in germany and that includes the government it requires major investments so if you want to digitalize an entire country it takes a lot of resources and that's also the case with promoting sustainability and there is still a long way to go as if you know me upside. these students are seizing the moment to press ahead to make perhaps eventually the larger world smarter greener and more sustainable. the use of science and technology can help

intentional action for the good of the involvement i hope even cottage to to be to use your scientific and book to help the you know what a big or small town i'll leave you with that part and see you again next week until they get back.
