What can make white plastic instantly turn yellow

Look at this report appalling: waste plastic turned into raw materials for the production of shocking: a large number of finished products sold to Xi'an and surrounding areas a worker is picking waste plastic bottles, ready to be sold to the plastic processing plant Core Tip In Xi'an, some places, a variety of unscrupulous channels to recycle disposable infusion sets, plastic bottles, disposable plastic cups, etc., after a simple treatment, they produce bags of plastic particles. These plastic particles are shipped to various places, most of them are used to produce disposable food bags, some of which are mixed into the polypropylene waste, into the production of disposable plastic cups of raw materials If not seen with their own eyes, who would not have thought that a variety of illegal channels recycled disposable infusion sets, plastic bottles, disposable plastic cups, condoms just after a simple crushing, mixing, will produce bags of plastic particles. These plastic granules are shipped to various places, most of which are used to produce disposable food bags, and some of which are mixed into polypropylene waste to become the "golden raw material" for the production of disposable plastic cups. ...... These "white pollutants" have a significant impact on the urban environment. "In the urban environment caused harm at the same time, but also a serious threat to the life and health of every person. Our reporter after nearly a month of investigation, a "waste" for "treasure" of the city's "white pollution" black chain was finally uncovered.　　Surprise disposable infusion tubes were purchased in large quantities The first section of the chain, is hidden in the "urban village" of some individual waste goods purchasing points. In Xi'an Yanta District, Weiyang District, Lianhu District, many "urban villages", there are many waste plastic purchase points, some of which are only recycled beverage bottles, and some are any plastic are collected. Some scavengers know that the state expressly prohibits the private recycling of medical waste, but still secretly sold to the recycling point. In Yanta District, Beiqitou Village, the reporter secretly found that some bosses explicitly do not accept these sticky mucus and even blood of the disposable infusion tubes, syringes, etc., but secretly in a large number of purchases.　　"Do you want infusion tubes?" The afternoon of March 24, the reporter came to a recycling point, a woman who is organizing the waste measured the reporter two eyes, did not squeak. But when the reporter's front foot just out of the door, she caught up with the back foot and asked: "Is the amount of big? New or not?" Learned only to ask the market, she quietly told reporters, large quantities can be negotiated, the price "are not losing.　　Unannounced visits to the reporter found that the medical waste sent to the acquisition point mainly from a number of small hospitals, small clinics, according to the amount of the size of the collection price is generally between 1.4 yuan per kilogram to 1.6 yuan ranging. Some of them are clean and of good quality, and the collection price is higher. A recycling point boss revealed that the reason why the collection of medical waste, mainly large volume, high purity, good sales. Often some good business acquisition point, is because of hospitals, clinics, a stable "source of goods" and do more and more big.　　"As long as you can make money, what do you care what you do?" --- unannounced visits to many recycling point bosses have the same mentality. It is this mentality, so that should do harmless treatment of medical waste from the scavengers fingertips, a little bit gathered to the recycling point, and then centralized flow to the second section of the chain - a hidden plastic processing plant.　　Tough processing, regardless of whether it has a virus In order to find these hidden processing plant, the reporter tried to find ways to recover from the boss of the point "set" the address of the manufacturer, but the results were disappointing. No choice but to squat and look for ways to transport garbage motor vehicle traces. After several days of squatting, tracking, March 25, in a motor vehicle to Xi'an North Second Ring Road still failed to get rid of us, tracking results.　　Soon, the reporter followed the trail to the junction of Xianyang City and Chang'an District, Xi'an City. Here, there is an area of thousands of square meters of plastic waste processing plant. Plant area stands side by side with four or five plastic processing plant.　　Several factories face south and north is located in an open area. Around the plant, is a large area of polluted farmland. From morning to night, the machine rumbles, pungent odor when the wind can be blown hundreds of meters away. The ditches crisscrossing the back of the plant are dedicated "sewage channels". A stream of white foam, mixed with various colors of slag sewage from the factory outflow, the stench is compelling.　　The factory door is usually closed, only when the delivery of finished products --- plastic pellets, only open the door for a while. Reporters to open a similar plastic processing plant on the pretext of the owner agreed to enter the plant. In the factory reporter saw, a large number of plastic garbage piled up, and leaning against the mountain of garbage, is a row of crushing pool. Pool water with roller-like gears in the mixing, chopping, black pool water, tumbling with infusion sets (tubes), plastic film, as well as condoms, disposable syringes and other things. The crushed plastic garbage is turned into pieces as big as fingernail caps, and one by one, they are fished into the tall furnace through a big strainer by a coal-black-faced teenager. While he keeps filling the furnace, a machine is attached to the other end, and a girl wipes her sweat off as she pulls spaghetti-like plastic shreds out of the machine, despite the heat. These black plastic threads were quickly cut into half-centimeter-long particles, which fell to the ground for a while before being swept away by the workers and put into the flour bags of the ×××× flour mill. Asked why to load into the flour bag, the workers were silent, the boss was beside the narrow-eyed smile.　　Reporter: Pool water this dirty, the production out of this (referring to the particles) dare not use? Boss: It sells fast! And do not eat into the mouth, nothing! Reporter: What if there is a virus in the medical waste? Boss: As long as the money on the line, who cares how much ...... See the reporter is very interested in opening the plant, the boss of the plant is very appreciative, even said "guaranteed to earn no loss", said each car particles earn at least 3,000 yuan of money, such as polyethylene, polypropylene raw materials rose, earning even more.　　The factory next to several factories also produce plastic granules, and the color includes red, white, blue and other kinds of. "This stuff can be done directly to the bag, thinner, can also be mixed into the polyethylene powder to do a good bit of bags, do disposable mouth cups can also be mixed." A worker revealed that do mouth cups also have additives, stabilizers, more trouble.　　Loss of "hit" into the legal store low-priced sales in late March of a night, the reporter "to follow the melon", tracked to Xi'an western suburbs of Damalu village near a plastic bag production workshop. The workshop is hidden in a residential courtyard, a room on the west side of the courtyard, two or three workers are blue plastic particles to a huge film blowing machine to fill, as the machine rotates, the other end will be pressed out of the long plastic film. Then instantly cut and molded, a look smooth, soft food bags were "born".　　In the three bridges, Doumen and several other black workshop unannounced visits to the reporter found that, in addition to a very few workshops also wash the particles, most of the plastic particles directly into the machine. The entire production process without any effective sterilization measures. It is this simple production, so that the average small factory can also have a daily output of about 600 kilograms. The output of slightly larger factories is even more astonishing. It was revealed that manufacturers who produce food bags from plastic pellets can earn at least 800 yuan a ton.　　Investigation of the reporter also learned that, because the bag "process" is simple, there are many processing plastic granules in the purchase of machines to produce plastic bags. Produced by the plastic bags are thin, impurities, odor characteristics. In addition, in order to pursue greater interests, some of the production of plastic granules of the factory simply through the relationship will be part of the plastic granules through the western suburbs of Sanmin Village, Daxing West Road, a legitimate chemical store sold at a low price, the price of these plastic granules than the price of the regular polyethylene powder to be lower than the price of more than 4,000 yuan per ton.　　From the first to the second section of the chain, mixed with medical waste of various colors of waste plastic instantly "new", into the outsiders simply can not see exactly the chemical raw materials. With the constant flow of these particles shipped to various places, unscrupulous manufacturers have a low-cost raw materials.　　Yin "feel free to use" cup mixed with old materials in the tracking of food bags at the same time, the reporter will also focus on the many people regarded as "hygiene" of disposable plastic cups. Why is this cup transparent and the bottom of the cup is cloudy white? Why pour boiling water, the cup will emit a choking odor?　　In order to explore the source of these plastic cups, to find the secrets behind the disposable plastic bags, from early April, the reporter from the wholesale market to the village, from a recycling point to the chemical store, to start tracking. As a result of disposable non-biodegradable food and drink utensils have been stopped by the state production, all the activities of manufacturers are extremely hidden. Not to mention the ordinary consumer is difficult to find its trail, law enforcement agencies are also difficult to find. After tracking for many days, the reporter set his sights on the market a large number of sales of "100%" disposable plastic cups. Because there is no factory address on the box, the contact phone number left can not be reached, the reporter had to be based on the box on the manufacturer "Xi'an Qicai Industry and Trade Co., Ltd." to the business sector inquiries, the company is located in Xi'an, Shangqin Road, the reporter immediately went to, but went to find that it is only a pop-up netting workshop, there is no sign of the company.　　So, the reporter folded back to the wholesale market and then from the wholesaler "set" factory address, but still nothing. Helpless, the reporter had to deposit to a large number of goods and short time for the reason that, asked to personally go to the factory to pull the goods. Wholesalers hesitated again and again, finally agreed to tell reporters to Wenjing Road, an auto body shop can be found. Thought I could find the factory, but found the garage was found, just a stacked disposable plastic cups of the warehouse. A staff member of the warehouse refused to disclose the factory address. We have no choice but to continue to track.　　From tracking the wholesale market in and out of the vehicle to track the warehouse transport vehicles, from the northern suburbs to the western suburbs, the highway running back and forth, almost to the reporter's patience is exhausted. After the Wang Temple, three bridges and Zaoyuan road waiting, tracking, the morning of April 11, we tracked the delivery truck even ghostly to Daxing West Road, Xi'an New Century Meidenggao Foods Co.　　Reporters twice to find people want to enter the company, were stopped by the guards. Around the company before and after the discovery, in addition to the main door, and then "no door to enter" in the case, had to pretend to buy disposable cups, who knew that was allowed. Into the company, the reporter according to staff pointing, has been inward, to the south, found a narrow aisle, a small yard parked two van-type "light truck", the yard came out of the click-clack-clack machine sound. Several workers are a box of a box on the goods, box printed on the "Xi'an Qicai Industry and Trade Co. While the boss is not in, the reporter will soon "factory" turned once. Factory is very small, dark, old houses. The westernmost is the main workshop, the east side of the air compressor, pull the film production machine. North and South two rooms a stacking boxes, a warehouse. In the film workshop, a worker is filling the mixer, snow-white polypropylene powder, gray, obviously impurities are old materials (directly recycled plastic cups crushed material and white plastic particles).　　Reporter: Where do these old materials come from? Worker: I don't know, the boss let mix.　　Reporter (from the mixer to pick up a piece of dirty yellow plastic particles): what is this thing, this can do disposable cups?　　Worker: a moment of high temperature will melt, can not see. Reporter: Why not completely with polypropylene powder? Worker: the boss is too expensive. Reporter: What is the ratio of new material to waste (old material)? Worker: one to three. Reporter: What is it? Worker: 30% old material, 10% new material.　　In the western workshop, the ground plastic fragments, particles can be seen everywhere, several female workers around a molding machine like wearing a hat constantly press out the plastic mouth cups on the thumb and forefinger, even if the mouth cups fall to the ground, but also put on, and then loaded into the plastic bag labeled "has been sterilized and disinfected, please rest assured that the use of the" plastic bag. In the corner behind this room, there are also a large number of stained disposable plastic cups. According to workers, these cups crushed by the crusher can also be mixed directly into the polypropylene powder.　　In order to find out why the cup factory here, the reporter yesterday asked the staff of Maideng high company, allegedly, "Maideng high and plastic cup factory has nothing to do. Maideng high company occupies a food factory's factory land, is the food factory to the back of the lease to the mouth cup factory." It was reported that an electromagnetic factory also rented land in the back. All vehicles go in and out of the gates of the Maiden High Company. However, it is puzzling, out of the United States high company gates, just "let" the reporter in the guard suddenly stood next to a security guard, the guard was surprised to ask our driver why did not buy a cup, the reporter had to say that the manufacturer let to the warehouse to buy, and finally be able to get out of the way.　　It is understood that a ton of polypropylene powder to more than 11,000 yuan, and mixed with white plastic particles (commonly known as white C) and recycled plastic cups crushed old material is less than 5,000 yuan a ton. Due to the rising price of polypropylene powder, the original underground production of disposable plastic cups, and now even more cost-saving production with old materials. The net profit of production in the meantime in about a thousand dollars per ton. It can be said that there is no old material, plastic cup factory pure polypropylene powder material is difficult to survive.　　Black each link to engage in "stealth" from the whole chain, if there is no last link - smooth sales, a large number of disposable food bags, plastic cups are unable to lay to Xi'an and even the surrounding areas. And it is relying on the wholesale market and small traders to promote these two ways, so that every link in the chain participants can finally profit.　　In Guoheng Food Wholesale City, Rehabilitation Road Wholesale Market, Jian Gong Road Comprehensive Wholesale Market, Jixiang Village Wholesale Market, Zhujiao Road Wholesale Market and many other wholesale markets in Xi'an, wholesale plastic bags, disposable plastic cups of the stalls can be seen everywhere, and in the streets and alleys in Xi'an, pushing a bicycle full of bags of food touting vendors are countless. Through contact, the reporter found that the reason why the sale of wholesale markets and vendors to promote these two channels, on the one hand, the problem can be legalized, a large number of sales, on the other hand, can also avoid investigation and handling, "safe survival".　　In order to "safe", the whole chain of each link, are very covert. Such as the wholesale market stalls do not know where the manufacturers, even if there are customers need a large number of goods, the stalls can only be contacted by phone, the warehouse with goods. Warehouses are generally more hidden, but find the warehouse, the warehouse also do not know the address of the manufacturer. In addition to a phone can contact the factory owner, want to find the manufacturer simply can not be done. In addition, the manufacturer to the warehouse of the transport vehicle, are manufacturers to find "their own people", these "their own people" in addition to keeping their mouths shut, but also for the boss to keep secret. And from the warehouse to the wholesale market, and are the warehouse arrangements for the car, the wholesaler is difficult to know its details. From all the links, its confidentiality is very strong. As for pushing the bicycle touts, mostly some illegal production of food plastic bags of small workshops practices, they walk the streets, rarely can be found by law enforcement agencies to penalize.
