Hainan's "plastic ban" road: the rebirth monologue of a plastic bottle

in a 24-hour intelligent garbage recycling station in Haikou, citizens can realize garbage recycling through it

have you ever wondered how many disposable non degradable plastic products are consumed in this land every year? 110000 tons to 120000 tons - this is the annual use of disposable non degradable plastic products in Hainan Province. Correspondingly, it is the pressure of treatment or recycling. It cannot be denied that disposable non degradable plastic products not only bring convenience to people, but also bring headaches

marine pollution and environmental protection caused by disposable non degradable plastics have always been a topic of great concern. In February this year, Hainan Province issued the "plastic ban order". From the perspective of non degradable plastic bottles, Hainan tries to present a microcosm of the chain of links related to non degradable plastic products through its rolling route from production, use to recycling. Maybe we can get a glimpse of the way to "ban plastic"

production: full of industrial flavor

one of the materials comes from oil, and it is difficult to degrade after hundreds of years

in the afternoon of April 8, accompanied by a short sound, an empty mineral water bottle was added to a garbage can on the roadside of Nansha, Haikou. This bottle has a net content of 550 ml, and the product qualification code is 34hkf1

before being put into the garbage can, the bottle cap of "34hkf1" was sealed and filled with water, and was placed on the store shelf together with other mineral water with different color bottle labels and caps. Before entering the store, "34hkf1" was born in a factory not far from Haikou City

softening, molding, cleaning, irrigation, labeling, packaging, transportation... The delivery of a bottle of mineral water has to go through this series of links

the birth process of "34hkf1" is no exception

its bottle body and bottle cap are made of pet and PVC respectively, which means polyethylene terephthalate and polyvinyl chloride in turn. The names of these plastic molecular formulas sound distant and strange and full of industrial meanings. In fact, it is true that one of the bottle making materials of plastic bottles comes from oil

the treated oil is transported to the manufacturer to make tiny plastic balls. The plastic bottle manufacturer melts these small balls and then molds them into a "prototype". The manufacturer in charge of bottled water filling will heat the prototype, reshape it into the desired shape, and then pour drinking water into it

"at present, Hainan's enterprises producing plastic bags and related plastic products have a total production capacity of 60000 to 65000 tons, which meets 55% of the needs of the island's market, and the other 45% are transported from Guangdong, Guangxi and other places." Deng Xiaogang, director of the Provincial Department of ecological environment, said

after a series of processing links, "34hkf1" leaves the factory smoothly. At the bottom of its transparent bottle, a small triangle in the shape of an arrow circle is printed with an inconspicuous image, with the English letter "pet" written on it and the number mark "01"

this inconspicuous number is the distinguishing code of plastic types. "01" means that the bottle body will deform and release substances harmful to human body when it is filled with high-temperature liquid or exposed to sunlight. At the same time, this number is also set for the convenience of sorting

plastic bottles with "01" digital logo are difficult to degrade. If discarded at will and not recycled, these non degradable plastic products will continue to age and crack in their long life. Together with other non degradable plastic products, they will gradually become micro particles, flow into soil, groundwater or the sea, and become a century old "fossil", which will continue to circulate in nature, or pollute soil water quality, or threaten marine organisms

out of the factory, on the shelf, "34hkf1" existence "timepiece" has just begun to take off. In landfills, a plastic cup takes about 450 years to decompose, while for non degradable plastic bags, this time may take longer

recycling: waste bottles can be quickly realized on site

the garbage that was discarded at random before now has a new place to go and has new value

"5 yuan a bottle, you can pay online here."

the shop owner quoted the price familiar to him. The buyer standing opposite tacitly cooperated, scanning the code, paying, taking the bottle, unscrewing the bottle cap, and pouring a few mouthfuls with his head up, trying to quench the heat of the early summer afternoon. The water was quickly drunk, the bottle cap was tightened again, and another empty plastic bottle was thrown into the lying garbage can of "34hkf1"

mixed with all kinds of waste bottles and cans, packaging bags, peel and paper scraps, "34hkf1" didn't know where he would eventually go until Liang guanjin dumped the whole garbage can

the sanitation worker from Haikou Longma sanitation Environmental Engineering Co., Ltd. was agile and skillful. He worked with his colleagues and quickly cleaned up the garbage in the garbage cans along the street. These garbage will be transported to the garbage transfer station located in Jinniu North Road, Haikou City

there, the "timepiece" of "34hkf1" will jump into another stage - recycling

"today, the real-time price of plastic bottles is 2.8 yuan/kg, and that of cans is 7.4 yuan/kg, which is clearly displayed on the computer screen." In the morning of April 9, at the transfer station, Liang guanjin quickly sorted and stacked "34hkf1" and other mineral water bottles together, picked out cans, waste paper and other recyclables, and put them on a 24-hour intelligent resource recycling machine called "quantum recycling", waiting for the completion of recycling and cash

show the QR code, select the type of recycled goods on the machine computer screen, confirm the weight of recycled goods, paste the order code strip spit out by the machine on the recycled goods bagging, put the recycled goods into the machine, wait for inspection, and automatically transfer the recycling fee into the account... It took Liang guanjin less than 2 minutes to put a gunny bag containing 4.11kg empty plastic bottles into the intelligent recycling machine covering an area of about 8 square meters. Lying in a sack, 34hkf1 is waiting for someone to change his fate

"in the past, we had to contact the waste recycling station first and wait for the other party to collect it. It took a long time." Liang guanjin said that the use of intelligent resource recycling machines saves them a lot of trouble

in fact, this intelligent resource recycling machine was installed and put into use at the end of January this year. Zhang Yun, the on-site person in charge of the 24-hour smart resource recycling station of "quantum recycling", said that since its operation, the total weight of various items recycled has increased from the initial dozens of kilograms per day to more than 360 kilograms per day, and the users include sanitation workers, residents of surrounding communities, merchants, etc

it is not new that waste bottles can be quickly realized on site. There is a deposit system for plastic bottles in Germany: people send empty plastic bottles back to supermarkets. Using the automatic bottle returning machine, each plastic bottle can be returned 25 euro cents. Stores must abide by the obligation of recycling plastic bottles

in the "plastic ban order" of Hainan Province, it is clearly proposed to implement the "producer extension system", which is intended to urge production and sales enterprises to use their sales networks to recycle discarded disposable non degradable plastic products, and recycle the recycled plastic products to improve the recycling efficiency

in less than 2 minutes, it was transferred to an 8 square meter resource recycling station, and the "life" trajectory of "34hkf1" began to change. Instead of being landfilled or incinerated as domestic waste, it was "reborn"

utilization: after primary processing, the low-cost plastic bottle slices are welcomed by recycled plastic products manufacturers.

Yang Xuecai, Secretary General of Hainan material recycling association and executive director of Hainan Lvbao worry free renewable resources Recycling Co., Ltd., will witness the transformation of "34hkf1"

"we will treat the bottle body and bottle cap separately. The PET bottle body will be sliced, transported out of the island and sold to manufacturers producing recycled plastic products to make recycled fabrics, etc.; while the PVC bottle cap will be used for other purposes." Yang Xuecai said

as a kind of chemical products, polyester chip has always been the raw material of polyester. Because its utilization rate is as high as 9%, it can better provide market service of 7%, and it is drawn by many garment enterprises to make clothes. Nowadays, the waste plastic beverage bottles are processed into filament after being crushed by machine. Its function is equivalent to polyester chip, and the price is low, which is deeply welcomed by recycled plastic products manufacturers

the bottle body of "34hkf1" will be transferred to Yang Xuecai's factory, stored after preliminary processing, slicing, crushing and other processes, and then selected a fashion ship to be transported outside the province for recycled plastic products

the ship loaded with plastic chips will go all the way north from Haikou through the Qiongzhou Strait to chemical fiber factories in Zhejiang or Jiangsu. It will take about 10 days along the way. In this "journey", each ton of plastic chips needs to be paid logistics and transportation fees ranging from 80 yuan to 120 yuan

"at present, the number of plastic bottles recycled every month in our province is about 3000 tons, accounting for only 15% of all recycled plastics." Facing the current situation of recycling non degradable plastic products in the province, Yang Xuecai was frustrated. He said frankly that the reasons for such an embarrassing situation were, on the one hand, the blocked front-end recycling network and, on the other hand, the lack of end use links

this is a long-standing problem. Liang guanjin admitted that the previous process of disposing of recycled materials was not so easy. This is not the only problem to face in implementing the relevant measures of "plastic ban"

in fact, since Hainan Province started the "plastic restriction" work in 2008, due to consumption habits, production costs and other reasons, the consumption and use of disposable non degradable plastic products are not optimistic

"the 'plastic restriction' work has a significant effect on large supermarkets. According to statistics, the use of plastic bags in large supermarkets has decreased by about two-thirds in recent years, but it has little effect on the farmers' market." Zhang Jing, the relevant person in charge of the soil environment management office of the Provincial Department of ecological environment, said that in addition to paying for disposable plastic bags in large supermarkets, consumers can still get free plastic bags from vendors in farmers' markets and other places; Moreover, with the emergence and growth of new business forms such as takeout and express delivery, the use of plastic packaging and plastic tableware has increased sharply

in Deng Xiaogang's view, there is a clear difference between "plastic restriction" and "plastic prohibition". The former emphasizes restrictions and adopts payment system and other means to restrict or reduce the use of plastic products; The latter emphasizes the prohibition. First of all, it prohibits the one-time non degradable products listed in the relevant directory, and fully utilizes and integrates the business and resources of the existing leather chemicals and rubber production base in Changzhou

in the "plastic ban order" issued by Hainan Province this time, it is also clearly proposed to reasonably plan and build plastic products recycling function points. Plan the recycling points of renewable resources in the province as a whole, actively promote the construction of relevant points and projects of renewable resources utilization, guide and support the development of renewable resources recycling industry, and promote the recycling and reuse of waste plastic products

question: what should be used to replace

through the method of economic leverage, the use cost of alternative products should be reduced, and the consumption habits should also be changed

the sliced "34hkf1" will exist in the market in a new form

after several days, the ship carrying plastic chips arrived at chemical fiber plants in Zhejiang or Jiangsu. The manufacturer will
