for the last four months, protesters have been rallying in hong kong. first, against a proposed bill that would have allowed the extradition of hong kong residents to the chinese mainland to face criminal trials. that bill has now been withdrawn, but protesters remain on the streets, asking for more demands to be met, including greater democratic freedoms and an inquiry into alleged police brutality. the protests have been watched around the world,

with videos uploaded daily showing highly organised groups. in the airport, on roads, and even in the legislature. but with no clearly structured leadership. this contrasts with the so—called umbrella revolution of 2014, a pro—democracy movement where individual organisers were targeted and jailed. this time, people are using encrypted messaging apps to organise in a more anonymous way and try to avoid interception by the police. china is a world leader in facial recognition, surveillance and artificial intelligence technology. so it's not unthinkable but they have found workarounds to keep an eye on the apps. danny vincent is in hong kong and he met two protesters who are trying to organise

without being identified. a smart lamppost being kicked to the ground and opened up by protesters. hong kong authorities say they're used for monitoring the weather, pollution and traffic. but protesters say they could have a more sinister purpose, housing a facial recognition camera for monitoring and identifying people taking part in the protests. they sawed it down to see what was inside. they claimed to find computer chips made by a mainland company linked to surveillance. i think the guys in the front line that took down that surveillance camera, they understand it might be a surveillance system that is monitoring its people. they actually might not know the entire technology behind it. lasers are another way protesters are using relatively low—tech solutions to disrupt the surveillance of the police en masse.

the laser pens are used because if you point it directly at a camera it will make the sensor of the camera a little bit unstable. it might buy time for us, it might disrupt the police from chasing us. hong kong has seen months of protests. these protests have not been organised by individuals. they have been organised by tens of thousands of people online and tens of thousands of people have also taken to the streets. much of the organisation has been done using online forums and encrypted messenger apps like telegram. this it professional and protester has asked us to call him tony. he is a member of several groups planning protests over telegram group chats. some of these groups have tens of thousands of members. the last time hong kong has had such la rge—scale protests was during the occupy central movement or the umbrella revolution. that movement had a leader. the government has targeted that organisation afterwards.

so this time around, people see that it is safer to participate in this movement without identifying themselves. without telegram, i can't imagine our masses would have imagine how the masses would have co—ordinated effectively, feeling secure that the police could not implicate us or prosecute us. some go to even further lengths to protect their digital footprint. meet alex. the phone i use isjust a normal android phone from samsung that has got military grade security. it works as a secondary android. it is behind a primary android system. it's two separate systems. there is a lot of passwords you have to input in order to get into that secondary android. it has military grade protection. it's very difficult for the police to trace me digitally.

he suspects the authorities are also becoming increasingly tech savvy. many have long suspected a loophole in the popular messenger app, which could allow the government to monitor communication despite its encryption. we suspect that the government has been importing all of the hong kong phone numbers into the telegram, or the police force telegram account, to help them pinpoint which person is involved in that kind of speech or involved in that conflict. telegram claims it has now fixed this loophole — but fixed or not, protesters are developing other methods of communication. these include using airdrop on iphones and the bridgfy app. both over bluetooth. bridgfy uses peer—to—peer mesh networking and doesn't need the internet to work. still, these apps may not be

completely surveillance free. sometimes face—to—face communication is the only means available. if the internet is not good and it is not feasible for us to grab our phones, it is better to do it in the field. this movement has also become an information war between the protesters and police. protester scouts take photos of police locations and spread the information online. after more than 15 weeks of protests, this movement shows little sign of slowing down. london fashion week has kicked off with all its usual glitz and glamour, and as the biggest designers take centre stage to showcase their latest creations and set this year's trends, protesters from extinction rebellion gathered outside to remind the world about the true cost of fast fashion. 80 billion pieces of clothing

are produced every year. and many of those are discarded not long after they have been bought. the true cost of fast fashion is now becoming apparent. the industry is one of the largest polluters in the world, right up there with oil and agriculture. and cotton production is a big part of its carbon footprint. almost half of all clothing contains cotton. well, lara lewington has been to sweden to see a facility which is hoping to refashion our cotton garments several times over. from the cotton fields to the clothes rail, it takes 20,000 litres of water to makejust one kilogram of cotton. and to put that into context, that is enough for a t—shirt and a pairofjeans. and that is why what is going on here is so important. at this swedish recycling mill, a fifth of that water is needed

to create a comparable amount of fabric. the place runs on wind and water power, converting cotton into viscose in a process classed as climate positive. these bales are stuffed full of denim, in this case leg panels from pairs of jeans. so although this facility could separate any metal fastening or even any stitching which is made out of something that isn't cotton, here, this batch has arrived all sorted already. but here, an eco—friendly chemical process is followed by de—dyeing the fabric. any remaining colour is then removed through chlorine—free bleaching. water then transports this pulp into the next stage, where it will be dried for transportation. resulting in quite literally a blank canvas to be sold on to clothing companies. and this is the end result.

a sheet of what is known as circulose, a type of dissolving pulp. that gets sold on and turned into thread which feels a bit like cotton wool, and from there of course it is used to make clothing. feels pretty nice. that is now made out of viscose and it is recyclable again, about five or six times. this was in fact a proof of concept seen on the catwalk a few years back. this was in 2014. four years down the line, this facility was ready to be opened. we are the first company which is doing this on an industrial scale. we are notjust producing kilos, we are producing tons of this, and that is very, very important for the industry, to realise that this could be done on a real

scale, and make a real difference. because if you just talk about kilos, nobody can make a change with a few kilos, but you can make a change with thousands of tons of material, and you can show the world that this is actually working. raw materials being sorted is just one piece of the puzzle, though. this denim had to be shipped from the us, although with scale, more facilities could open worldwide, reducing the carbon footprint of that element. and how about the labour afterwards? that is not in renewcell‘s remit, but it is of course part of the bigger picture. meantime, high street retailer h&m, one investor in the company, will soon have clothing originating from this process on their shop floors. but the big dream here is that by 2030, the clothing industry might use 100% recycled or sustainably sourced materials.

and while that may sound unachievable now, clearly, times and attitudes are changing. that was lara in sweden. and that's it for the short version of click this week. in the full version, we have more fashion fun, and you can find out why i'm wearing these attractive goggles and this alarmingly tight green t—shirt. that is available on iplayer for you to watch right now. don't forget, we live on facebook, youtube, instagram and twitter, at @bbcclick. thanks for watching and we will see you soon. hello, once again. i don't expect any complaints about the weekend's weather from anyone who spent both days

in the south—eastern corner in the south—eastern quarter of the british isles, and eventually a good part of scotland got to see some sunshine to finish off the day. so, too, parts of northern ireland. it's the bit in between that's been a bit of a problem, given that we've had this weather front, a great banner of cloud — still enough to be producing the odd bit of rain. not amounting to very much, but pretty miserable fare, continuing its journey south overnight, filling in the gaps in the cloud that brought the sunshine in the south—east through the day. and that complete blanket of cloud will keep the temperatures up, but where it's more broken to the north of the weather front, temperatures really tumbling away — borders, for example, 3—4 celsius as your night—time minimum. but at least you have the chance of starting monday with some sunshine. yes, there will be some gusty winds across the north, and again a rattle of showers on those. further south across wales, the midlands, east anglia and all the southern counties, a lot of cloud here with the odd bit and piece of rain gradually fading through the day. no more 26—27 celsius,

we are much closer to a high of 20—21 celsius, many locked into the mid—teens. now, many of those showers through the evening on monday will fade away overnight. the skies with broken cloud, so some clarity. and again, that will allow the temperatures to fall away for many of us down into single figures. for the dry aspect of the weather in the middle parts of the week, we've got the high—pressure to think of, but not really tapping into the mild air. because of this high just at the moment, the flow on its eastern flank is coming in from way up towards iceland so, there is a decidedly cool feel about proceedings to the far northeast of scotland. the warmer colours are there to the west end to the south of us. but tuesday is a pleasant enough day — if you've got outdoor jobs, this is the day for you, most certainly. a fair amount of sunshine around, as well, but not doing that much for the temperatures. i'm afraid you'll lose your sunshine across this north—western quarter, the first sign of rain eventually getting towards the western isles later in the day. moving from tuesday to wednesday, the centre of the high just beginning to move further east,

cutting off that flow from those north westerlies. it will be a slow process, but gradually through wednesday, thursday and friday we'll find those temperatures ticking up by 2—3 degrees. that's it, take care, bye—bye.
