The same is the pure water sold in the supermarket, some purchase price is 12 yuan / each (24 bottles), and some are only 8 yuan, or even lower. What is the difference? Manager of a water plant in Daqing City, manager Ma told reporters: some water plants recycle used plastic bottles after processing and reuse, not only the price of bottled water is low, the quality is also worrying.
In order to find out the "inside" of the old plastic bottle into a beverage packaging, the reporter lasted for several days, from Daqing, tracking to Anda, and visiting Harbin...
A tracking truck to Anda
On the morning of March 11, the reporter followed a scrap buyer who was pushing a tricycle through the streets of Daqing City until 14 o'clock, and then followed the first destination, a waste collection station in Dongfeng New Village. Watching him sell the scrap on the car to the acquisition station.
B to find the source of the preform
The next morning, the reporter came to the waste collection station. Soon after, a truck drove into the waste collection station, and the staff loaded the woven bags filled with plastic bottles such as pure water bottles and beverage bottles into large trucks. After a few minutes, the truck left the acquisition station.
The reporter followed the truck to the factory of the development team of Anda City Development Village to crush the plastic bottles. Looking far away, the tallest "building" here is a hill made up of plastic bottles.
After entering the factory, several workers were busy under the “bottle mountain†covering nearly 100 square meters. Some of them were sorted according to the color of the bottles, while others were pulling the classified bottles to the factory. In front of the building, hundreds of bags are filled with sorted recycled bottles and shredded materials.
At this time, a worker found the reporter. When he learned that the reporter was coming to buy materials, the worker introduced the reporter into a small house and brought it to the owner of the factory.
"What do you buy for?"
"Blowing a mineral water bottle."
"What color do you want? Blue or white?"
"Pure white, can you make a bottle of blanks here?"
"I don't make bottle blanks (the PET material is processed and formed into a pure water bottle), but there are a lot of people picking up the goods from me. What do you mean by doing, I know what to give you. â€
"The people who come to pull the materials are used to blow the bottles?" asked the reporter. "They used to make billets. Playing billets and blowing bottles is not a factory. It is usually sold after the billet is sold, but most water plants can blow the bottles themselves."
Subsequently, the reporter visited some of the nearby waste plastics repo points and found that there are certain technical thresholds for the recycling of plastic bottles, which are basically concentrated in some areas around Harbin. Moreover, bottle blanks can be purchased in some stores in Nanxun Street, Harbin.
On the morning of the 15th, the reporter went to Nanxun Street in Harbin. In more than an hour, the reporter visited dozens of shops and did not hear the whereabouts of the bottle.
Just about to give up the search, the reporter approached the boss of a plastic processing factory, and led him to the factory. After opening the iron gate, the two men came to the reporter with vigilance. After Wang Bo explained to them, the other party relaxed.
The reporter saw that in this residential building, a snakeskin bag was piled up, and two women were operating a machine in a 20-square-meter room. In the corner of the room, there is a 1 meter square container with some scrapped scrap and some PET pellets. Wang Boss said that such a small workshop has an annual production capacity of 20 million to 30 million, which is a relatively small one in the 28 or 30 similar factories in Harbin. Boss Wang told reporters that in the process of processing the billet, the ratio of new materials and scraps is determined according to the customer's price - the customer's bid is high, all use new PET pellets; customers want to be cheaper, add some scrap If the customer wants to be cheaper, they have to use all the waste. "One sentence in total: a price for a kind of goods, what you want to give is like."
When the reporter asked Wang Boss, what is the enterprise waste, Wang Bo told reporters that some regular water plants are asking for higher; some black water plants that are unknown and undocumented are basically cheap, they buy how is it like. Wang Boss suggested that Dongfeng Town of Harbin is a distribution center for plastic waste in the Northeast. There are many PET bottle crushing factories there, where you can go.
C shocking Dongfeng Town
At noon that day, the reporter arrived in Dongfeng Town. After many inquiries, I learned that there are more than ten factories engaged in the recycling and processing of plastic products near Fengguo Street. They first sorted the recycled materials and sold them to different manufacturers for making water bottles and beverage bottles. Plastic pots, woven bags, fiber and other products.
At 8 o'clock on the 16th, the reporter went to a factory in Fengguo Street and was immediately shocked by the shocking scene: a few hundred square meters of factory buildings and a large courtyard filled with woven bags filled with used water bottles and beverage bottles; yard The surrounding area is covered with barbed wire to prevent the bottles in the yard from scattering to the outside; in the open door behind the factory building, plastic bottles are rolled out from time to time.
In the factory, the crawler belts on the machine transfer the well-used water bottles and beverage bottles to the machine from time to time. After the bottle is pulverized, it is dropped through the slide into the washing tank. The water in the sink has turned black and yellow, and the water is still floating on the water. The staff is holding the fence and stirring the pieces of the bottle from time to time.
The reporter reached out and grabbed a piece of plastic debris from the sink and found that the pieces were not only lubricious but also smelly. "The industrial firewood is put in, there are some other chemical materials." The owner of the factory told reporters. Later, the reporter went to another factory less than 200 meters away from the factory. The boss here told reporters that some of the people who bought their recycled materials were sold to Liaoyang, and some were supplied to local preform plants.
D factory is cut at the price
On March 19, the reporter contacted a Zhejiang boss who sold recycled materials in Dongfeng Town in the name of purchasing recycled materials and bottle blanks. He told reporters that he could take a reporter to see a bottle embryo manufacturer, and he told reporters: It means that 70,800 people are needed every day, so that manufacturers are willing to meet.
More than 20 minutes later, the reporter and his party came to Zhihua Packing Products Co., Ltd., located at Hadong Road, Daowai District, Harbin. The iron gate of the company's compound is locked, surrounded by a wall nearly three meters high. After knocking through the door, I haven't seen anyone open the door, and a fierce bark has sounded.
After entering the house, the reporter saw a sample of many bottles and some plastic bottles on the shelf on the right wall.
The manufacturer Zhang asked the reporter: "Do you want material B or material A, or sheet material?"
"What is A material, B material?"
“A material is brand new, B material is two-in-one (recycled material and PET new material), and the flakes are full reclaimed materials.â€
“How much is the new material?â€
"Do you want to bring a ticket or not? If you don't have a ticket, 1 point is 2% 5. A bottle of 18 grams is 2 hairs and 2 points."
"What if it is two in one?"
"The difference between the two in one is 1%."
“Do Daqing still buy a blank in your company?â€
"Not only your family, but several of them get goods from me."
E "rebirth" plastic hidden dangers
According to relevant national standards, food grade containers cannot use recycled materials as raw materials. In fact, a large number of PET bottles on the market are still being processed into new bottles.
Dr. Meng Linghui, deputy dean of the School of Chemical Engineering of Harbin Institute of Technology, told the reporter that the new PET is non-toxic, tasteless, and has excellent gas barrier and water properties. It is widely used in food packaging.
Food grade PET containers are required to be completely new because there is no way to ensure that PET bottles are not contaminated after they enter the market. In particular, some water bottles will be trapped in the trash and recycled again.
In addition, after the second melting or even melting of PET waste, its physical and chemical properties will change. High temperature will cause PET to produce some toxic substances, which may cause cancer.
In addition, the performance of PET materials that have been recycled many times is reduced, and the adhesion and folding resistance are reduced. In order to improve its stability, some processing plants will add industrial salt to it, which will carry certain heavy metals. After the water bottle is filled with water, especially after long-term storage, these toxic substances will be diluted in the water, thus endangering human health.
