Like to come and see to show you what i found and to investigate how your just kind of computer equipment found its way to god. This is the moment that i have been waiting for to listen to the other side of the story. Good morning. Who was doing it casually but then he want to come this way with me about the. Cycle of the os attacks some of the he wished the good saddam didnt dawn on him well college of nursing is if youre my School Student some garlic salt Bank UniversityYoung University in london so you go fast bread of the england you know let me show you the place where farmers equipment. This way i keep the waste. Cut. It off. Its terrible to mark such an emotional he says sam of all the africa oh hes your specific bastard i figure well well were having problems when we have nigeria and of course god you know these 2 countries are the major countries. You see even literally. It is researched as far as we can learn that particular piece of waste from the serial numbers look in there to me which on 20 years ago. I mean the article was for to be ethical was. Or will recall mission and given the challenges account for their own call it was but i will think anybody actually thought things through what happens when when it is normal that in you. Were not able to complete the training to find all the good men from leeds we went to because a deposit on to a Community Organisation would have committed lizzie she no longer exists. Really southern weather for that were not able to get that much information that could offer included the story for me. This is the piece that i found in gone from a dump site its only with the belong to do be sure constabulary and i really do want to bolt it in 2000 yes we put the story on the front page because we knew that people would be outraged that their daughter should police you know were somehow getting their equipment on a landfill in guyana was a difficult investigation the story i had to fill in the press offices several times and to push it they said that they at that time were using a contractor to deal with their waste and it was the contractor who had arranged well for the waste to be disposed of and so i guess there was a little bit of them saying its not really us here its the contract. A waste i dont think people have quite grasped the seriousness of it and can brush it away to a certain degree in the. They wouldnt necessarily mean it was kind of other crimes with drugs and so on. And you look at those speeds of equipment yes you realize that obviously theres a loss of time but it belongs to them should not the letter yeah it does not really please youve come away from gone with this and let me 1st to apologize to you and all the people of gone and it was happened it shouldnt happen this to you and acceptable to most of the time you find children some as young as 5 dismantling and burn in these ngs and exposing themselves to very toxic chemicals yes the police at the time did use a proper bona fide the licensed recycling company to recycle old computer equipment had to be replaced if you conduct formal investigations into what happened in london standing is was cry alone subcontract the chain from the company we were using that was called broke already ceasing. Then we should at least come from possibly only from one person from one of his Asian Company to the other because they were very difficult the one who is acting to block and went. With it my name is mike and i mean people trying to reach to into. Our 2nd issues and you have. Their. Gratitude for certainly betake grove where they came to america where theyre going and youre making very good news here are neither here nor here. But you and i have not been hearing it and i. Am very much support and i have been to several places in the usual this cues as has been 20 years or we give them to charity and i find these as cues rather funny. You know because it doesnt take away the problems it doesnt take away the complicity and it doesnt take away the fact that we blamed. Today business on the fish for 2nd plan for the u. S. And spain. This is. Generated by developed countries should go for recycling. The shredder is done using proper equipment with a hill specialized machine. Which is protected. You dont have to use the bit like the children in dumb side enough for. All. Up to 90 percent of the materials i reuse. Let me ask you this question you have this wonderful recycling facility and so why do we still hope the little electronic was illegally being dumped in gone off for instance. They dont. Go to the black market to look. I dont know but really it is that we are safe 25 percent no mater what i consider wrist what does it go i dont know. Become to my country ready ready ready ready ready. This is a tracker for money during each wastes so in this way we can control what are the movement from didnt quite extreme point to their treatment plans. So it means that once it is installed in the us you can full of the movement. And possibly notify him of this to mention here just for him and. I think this very important so we can get to simply live wire to send it in the way of these things on board this go. Now we have yes this. Computer we can follow this ng now from days that allows. We can see down the street where we are going to the next. Im taking the discarded computer with a tracking device to the public collection point. I wonder where it is going and. This we sold you how we control all the money devices this is the battle of the small need because an indication of the street where we have placed so we can go that if we can in this to field so we have every other week share of the players we have received this monday so its possible to track all the way to gone there yet so we dont see this thing not all we can say is sing gonna. You dont ask my National Opinion ok i was happy to put them up on this fancy globus he. Doesnt i was he was in the look at us ill just go. To. The underside it has to be a dental decided it was a skin idea that little. One everywhere if it has. To be which is the given and i thought id been dubious and we got the door to the house and it went on in the other another innocent to stick it out at another house because what us is really about on are not a mother this come by the city be go to the opera but i think we ought i think you are aware of those. Who are less that he is on the eve of. The end. Of the bill but ive had people yes ive got to be up. To. The name of that ive had a lot to let me see if theres lookin out you know a lot of that building where stock is the list of middle space how to see the masses will tell you about the. Less police units d. N. A. And all now been adequate it is going to go to cisco so yes there will be a battle. What the all projects trucking the movements and flying album locations of it was what are the findings to do share that with me i think its the by cisco so a different story in some cases it was all the less than half of the devices they are rife on a fisa authorize is leaving a little nyquist yes what happens is that he was there is a bird in a market is it is your story insulting is because it has some of these value so if you have and you can take these he wastes to an illegal market where you can sell these devices through out of attaining a benefit. Responsible for that you needle shipments and dumping abuse from africa and gone. And im investigating agencies and you which are doing i used to expose and come out what is a crime. Why does it all go wrong. For research we found it was leakage of an inversion every stage of the process here in the u. K. At least half of the short waste and is about market. Move in china exposed like our child gets diverted. He set out for a Company Based in hong kong and we then put together some of the vehicle hit list of countries we thought were suspicious and we contacted those companies to see what theyre offering. I know thats a few meetings with this companys. Story was that one of our customers from the other goods in china asked us to secure some supplies of c. Azziz katherine choose from from europe and so we were just presenting us i was going to middleman if you like yourself because its your field and we will. Just call the guy when i was inferring call is something these than europe and hes able to say you know we can get your 1000 pretty quickly we get them from a major recycling firm he said yeah a lot of them love. This law or medicine so it was a computer use it was a result of income or something so we have a really small of a wall thing its huge is that small towns but its he she set it on for some good stuff from you know the. Whole staged does that he was good i bet it members of the public to you know hold a choice agreement to civic i mean seaside you know council dump site at that point these sites are run by by companies they subcontracted by the local Authority Local council to miners the waste but often of these locations as we found theres ferguson shutting 2 Small Companies there deal specifically with the other child waste and instead of this material being recycled its is simply put in containers and shipped out to places like west africa and the far east. Resident. For the better you must deal with people to. The star resort could be to suffer through before you leave. And what is the motivation why is this so much he was been sent to got to the most recent strain is just pure money pure profit if you can receive a payment from a local council. Its a contract to 200. 00 this waste and then instead of recycling it simply put in a container and ship it out youre basically getting paid twice or because youre avoiding the cost of recycling and you maybe give us some money to pay for the far east. Die good idea i have a bag stored in fun and then it glows in heaven and i wouldnt feel whole nuts muncy contain i get pissed. We have full of electronic shots when that falls on does i owned illegal. We do want to close the loophole which is leading to so many electrical goods ending up in developing nations being taken apart by by children bonfires and dumps. At least kenya he had to hope michel he does in gods own fucking elect was shot into the tibetan and it was an awfully kikes but cute one is just my nominal mischa to top it. In the center of my view does this mean does down mark a name as i suppose. The elect to live in an age say about eagan must convey as i say this to me and. This is a very toxic waste stream for ng and europe we are wasting what could be and should be used again mom it would know she would up us to ski vanya masoud off to the productive it all before lectern each next 23 years since cousins tot mom in the suit off to the top that. I would assume. With or without the 3. Yeah bro i. Should know im best in is. Gods elect. Media elite so im biased being a flea conscious linda expletive. Does da neednt be exporting us alice beleaguered with some documentation with snuff eyes most innocent was off watch that. It was interesting seeing the port in scotland and having a feel for what is actually done why we pulling these ship limbs of use. They are actually open a container in my presence in the for me was so important. And historic lesbian west africa play model in nigeria over the last 3 years we have noticed an increase to ghana one of the usual tricks but these illegal exporters use is an example changing that contain a drop off point last month so as we cant be there to check our potentially have and material in the past feel fear of the container of our walking or the butts of until something behind us is not working although. Theres a lot of money to be made an explanation to them that we estimate the number that exports are organizing it could potentially make up to 5000. 00 pounds in a container. Of the container and inspect the material to see if its waste a moth. Is wasteful chikor might not be private to them and be illegal so due to the very thing you could measure functionality not of this angle of covering the amount of exports that is placed in the us or someone because the fact of the use of resources a fact of life. Can come a spike to check for back up the container from. Your checking before 2 for the container but the camera was no longer there is to be endless as little as another and occasion thats why the majority of effort goes into that. Is of intelligence and the use of inspections on analyst day. Weve already out information for mags both sure that each of the frenchs had been tested when i was a small object in children and people of the governess marched up. Crap. For me i would say that the control that i saw on the port in scotland was not good enough every single item would have to be checked for functionality particularly of the continence it was refrigerator is a bit slow on television several computers to talk to finally the idea waking in good working order before this should go with a day just jump.

It is possible to fully clean the premises off and skeletons but what you then leave is. Evidence that you have fully cleaned the mystery wanted to give its the end of the started speaking about the old before even the so b. Cover it up with just as dramatic a shot you are in a saudi consulate on aljazeera. On how hed seen in doha with the top stories on aljazeera police in hong kong have fired bullets and tear gas at demonstrators disrupting the 70th anniversary of the founding of communist china some demonstrators built barricades and set fires on protesters shot in the chest by live fire is reportedly in a Critical Condition in hospital sarah clarke has more from hong kong. Live fire has been used a lot of bullets been used 2 locations a young my type on the telephone side and should one thats in the New Territories and thats where that boy was shot with a boy teenager the reports suggest local media that hes 15 or 16 years of age in a high school in a Critical Condition and undergoing surgery in queen Elizabeth Hospital thats one report of a lie but weve had. All like haitians theyre all there at the rally points across hong kong tonight. Well despite the violence chinas capital is marking the anniversary with mass celebrations. Well the performance in beijing tops off a day where the countrys military might its was on display the celebrations are designed to show how much has changed since the peoples republic of china was founded the message is intended to be born of wealth and power. Police in finland say an attack at a school has left at least one person dead and several others injured the attack happened in the east of the country its understood the suspect charged into. The building with a bladed weapon began stabbing at Students Police apprehended the suspect. Reports suggest the us president sought the help of another foreign leader for political gain the New York Times says donald trump asked this trillion Prime Minister to help investigate the miller probe trump is already facing an impeachment inquiry into what was said in a phone call to ukraines president s perus police and military chiefs say they still support smarts and discourages president s to sprains Congress Voting to suspend him from Office Opposition politicians have symbolically sworn in his Vice President after his car dissolved congress to stop electing judges to the constitutional tribunals but the opposition members defied the executive order and remained in congress for the votes that see up to date stay with us an aljazeera news continues after manmade on the wastrel. We dont have a law in this country for building that type of export right now electronic waste is the most traded Hazardous Waste it is recognized as being the most severe problem with respect to toxic trade and it still goes on every day from our ports here in the United States. Says the country that is the wasteful country. And produced most of the waste. And all the different types of brokers in explorers out there say were inside all 3 of them and all the time they cozy up charities and say well give this very nice there is help for so much money. But basically its all about filling up a seagoing container. One of the things weve been able to do to demonstrate. As to how prevalent this type of exporting is we will just go around to these people calling themselves recyclers and you drive by them and the beauty is that you cant hide big old 40 foot container. Theyre all at a loading dock so these buildings are designed so you cant drive them into the building. So its very easy to photograph them and they have prominent numbers and we take pictures of those and we date them. I can type that number into a database called track trace and here we see the whole record of that particular container and its last weeks voyages its gone from thailand to singapore now its in new zealand. Weve been starting to get this data which nobody else has was really the flows look like. It comes through concord almost 65 percent of the time from us we didnt know that we started tracking and tracking tracking wow theyre all going to hong kong. Come from every way oh uncle from the United States of america from europe and even from africa. Every day do about 80 ocean going wessels coming into hong kong and 63000 boxes in containers coming into one does it really is a huge number right. This market is just one some places that doesnt always and see if they can find some little holes they can run but they falsified the descriptions of the decoration. So as they tried to. Deceive their customs of officials but i can tell you that districts will get. A receipt back to high risk on janus or ships for processing. We have 2 types of x. Ray scanners we can scan in a truck in less than 2 minutes the whole truck bombings. His movies put a container under the scanner because season one is us. For you ways that we have a number of kaizen apos failures and most of them are the credits posix scrap metal scrap. We intercept a container and not just face and process the container container is being repaired traced back to the states and then to have a successful prosecution in Hong Kong Hong kong company and the us company also. We do not process each and every container coming or going out of hong kong around a while theres no no one Customer Administration that can process 100 percent of them. Always want to do something to make some change so i joined going peace in 2002. First can pat is launching only waste. To sing these amazing and the really shock we can fund of the. United states you waste in hong kong. Farmland. I heard about the waste from the always see coming to hong kong 1st store in rio. I checked my mobile phone that i found here of a big contents ariel we have here. In this region. You can see. The 2nd book and not a whole. Thing. Coming from the human mental Protection Bureau in the United States you know what i was going to do we were we were going. d United States government feel we still us the United States not send that waste to out of country trying to. Meet you if you use a real name spoke to us from here to manage on. The trucks and reload in New Territories and drive across to very close and they have to pay a bribe is the only way they can get across or use a small coaster boat to go up the pearl river delta into areas like man high and there again you pay a bribe to unload it. When we went. We dont see any signs to say ok this is but we just its male the some male ok we know we arrive that way. Every year. So median ways to look from overseas that the United States and europe in japan korea l l l l at least home over 80 percent local people make life depends on u. S. Cities are. This is very typical local family will show. The world has recycled the plastic or c r t. The sky used to light to burn the plastic and cars 5 difference have. The walk dont have any protective mask to protect their health. This isnt a daily life they will. Miss family books are people used to pick up the. Expensive metal from the cheeks. And the bad scene is the waste i see people using the word im going out into the river so local. That has been floated way by the. End some of the children jump into the river mystery black is full of hate. But always feel resigned. Meals when he even mental friendly is good but People Health harm and the local environment also well. Really whats happening is people are extra lies in cost you dont want to solve the problem youd leather let someone else deal with it and youll never have to pay for it you dont ever get a bill from china saying you contaminated my land you have to pay. We are all the time appalled what is one of the biggest balls that we have in this country. That is so much from where you were little ships coming in here from all over the wall. It is a very lovely beach i mean a coastline in ghana here its marvelous is beautiful. But its not done so your hobbes to realize that most of the ships that are coming into the port made it would contain is the balls up so much in the 20 which. Well be Environmental Protection agency you know that is the responsibility of educating for no more and so some of these a moment the problems. So when you say other countries of origin a little has been shipped to grown up. Countries of it of the can. We realize that about 60 percent of it comes from here and then the new used equipment not the qualified as wished. So for me the whole thing is being is for economic reasons and it is all organized like in business is organised. So that makes a criminal theres a cascading effect we big money for the book as who are mostly europeans then how do the middle group being africans who are involved in putting them in containers and bringing them here they also get a certain proportion and then when it comes to look at market them do was all in one statue was on selling and other things what is the way old what should be the solution we didnt have laws so we have developed a draft policy which was in the palin meant to say that we can prosecute in country once we have the laws passed nationally that is our empowerment and we can stop it and sell it in the government is to say things. That you do to get on my team responded by 6 months doing that persecution and then we got even undercover as agents. He was was one of the biggest areas that we looked into for example most fraud have been through the east system. Customs have a form of valuation for say Home Appliances so its an evolution is next to nothing. Somebody goes to clear used clothes from the wests and they look at it as on damn good so we are not going to pay the value that you would be ordinarily noble. He does this thinking about them but meant that not even their ministry not even their customs offices all that they care about is that you say he didnt mean them to be used and ways that might get from the aimed at and. To. The intake right instead of credit taking booze for pop and we should. Use. The minerals and if it did you see this as of his as walking through the 1st afforded him cells that became somebody think its useful. To scrap the law to come in on this done by at the point waiting for dave barry is to declare or declare some of his system to play and most of them must occur and thats way the take if. It was not then they anybodys need to check it if you could see if i had a Disability Fund but told that this is it it may have affordable for example if you think about tape people it was the only way can really be about 2 or 3 but then that people would buy a little reliable and do some repair work on it you want to give it to make comics tools you can look at it to see what had become repaid. With the doing and. In the. Evening go to. It. And. This machine then need to find out about how this is not. An action that is when its working and then this one through the 4th wall from the legion of egypt. If i find out where the forces and things are a few names. In. The offing cop is no easy thing for a film guest on 3 guys movies so enough isnt just the same since. The group comes to buys schools of the season 2 things. Majority of good mans about 90 percent of americans would want to depend on these 2nd homes that provide. All the new forms new laptops but it is still expensive but to pull up the money it will fall these the. G. O. P. Will say particularly some of those behind it should be able to say that while were trying to bridge the Digital Divide between you very kind and the rest of off it can go. But the reality is that these computers didnt last and theyre not helping anybody here. In. The group are. Believe it were going to come back under the knife thank you very much ok to business or places. For the royal baby this is that the primary area and most of the children come from deprived homes thats probably going to bring to mind already. On my knees a pool of money time and more money to buy named everything but you know. When all was brought everything was taken all right i says tell us in dan you saw that if you press it to get any to not come out then the outflows need and they were tingles off its really worked for how long how many months. Before why a year. Not from an idea who it is obsolete said virus attack day to deploy its possible if not see the disk. So this is not that. This is the old look where they are not liking them when you test out will key so break into 2 with on the buy says its not working out to buy some memory and some heidis and others the change they look at a price in town is a specific kind. Of thing is all for control when jimmy talked with vertical companies you would in the hope of. Positive those old equipment dust up and recycled or disposed of and then as that is just a hobby to dump on one to the electrical items. Here you find young boys some age between well lets say 5 from 5 all words you know breaking this month cling these computers and Television Sets and the burner most well to salvage the metals and then particularly couple. To go to waive it and then the middle name would put these things together and sell them to other companies and theyre shipped to every part of the World Companies that would need them to buy china. You know anybody who wants and. Meeting the people who own these literally right to life owning god was indeed a mixed feeling for me ongo saddam is then of course. George. Isnt a very difficult thing going number one frustrated but im not going to give up. My government should not be a place to recycle or disposal for the wisdom of a couple of your colleagues and every country should learn to disposal recycle its all just. Not a lot of the kids tell me that well when we break these things we burned we have paid deeks miscreants headaches. Isnt a call for us to run i mean that they have all respiratory problems theyre not able to breathe free will. In 10 years i want to see the kids in school i would like to see the kids do want children to play in very clean surroundings and not state all the other dumb sides and burning all these things. Because to them it has to stop. Hello powerglide its remarkably hot recent time and time again of the last couple of years monday was and another example this particular Time Temperature of 42 the obvious 34 september that will be the record for october 43. 00 is a record so even at least equal it now has changed a month and is still 40 degrees theres a front line of green which will bring some sort of cooling which will get there i think during wednesday down to 27 but well see the return of heat the line is the seasonal one right in through bolivia thats through ecuador and beyond to colombia and those potential for that cloud over brazil. Yet more showers the next day also the caribbean still quit quieter than it was but the great trying to these these big white clouds represent the dailys under storms and its quite active at the moment so anywhere really from. Say Santa Domingo west was towards cozumel in mexico city is a line with the potential development of big thunderstorms and thats true size throughout somalia and costa rica thats true the next 2 days know also that big sunday storms again have been vicious ones i have to say in the u. S. Its a line its developing across the plains states are the side a difference of 10 degrees big thunderstorms. Sponsored by town and. On the streets of greece and violence is on the rise there or you have to go from other potential and this and that both of those results from fusses. And increasingly migrant farm workers are victims of vicious beating. Is helping the Pakistani Community to find a voice the stories we dont often hear told by the people who live them undocumented and under attack this is 0 on aljazeera one of the really special things about working for aljazeera is that even as a camera woman i get to have so much empathy and contribution to a story i feel we cover this region better than anyone else would be what it is you know is that it turns out in the butt to be heard because you have a lot of people that are divided on political issues. The people who believe to tell the real stories are just mended is to do the work in depth journalism we dont feel inferior to the audience across the globe. International trade swill years of food and having free trade with nazi germany or the japanese or chinese dogs or germany controversial immigration policies that anyone who has a well founded euro persecution should be able to count on the off ministers from syria has closed the door to Syrian Refugees like the buffalo maybe her son goes head to head with senior trump advisor Stephen Moore this year the trump deficit crossed a trillion dollars you will be urging the world not to reelect a little from well i dont know how to go on. This is aljazeera. Follow on how my he did in doha this is the aljazeera news are coming up in the next 60 minutes. A new level of violence in Hong Kong Police use live ammunition against and see government protesters one person is shown in the chest
