With the continuous introduction of various policies at all levels, merchant preferential activities are frequent, and some people around have experienced it first...... During this time, if you don't know how to trade in your home appliances, you won't be able to keep up with the trend. After the replacement, where will the waste household appliances go? How to recycle? Follow the reporter to experience this wonderful journey of turning waste into treasure.
First stop: recycling
A waste recycling service station in Yuhang, Hangzhou, is home to old household appliances such as refrigerators, TVs, and computer hosts.
The mobile phone prompted a resident to place an order, and Master Luo Dahai put on his toolkit and set off on an electric tricycle. This site receives recyclables from the surrounding community, including a lot of waste paper, waste plastics, and waste home appliances.
Leaving a resident's home is the starting point for the recycling journey of household appliances.
Luo Dahai has been working at the No. 1 site of the Tiger Recycling Service Station for several years. During this time, when he went to the door to collect, some residents began to ask him, "What is that trade-in?"
When it's fast, it's a matter of minutes to move a home appliance.
But Master Luo also encountered a problem: a door-to-door recycling, to the resident's house found that it was a double-door refrigerator, the door was very small, the refrigerator could not be lifted out, it took several hours, the resident also found a professional to dismantle the door, only to move the refrigerator out.
Since it is also responsible for recycling cardboard, plastics, etc., this service station may receive an average of 50 orders per day, of which about 10 are used appliances per month.
"Appliances are available every month. Master Luo counted the recycling records in his mobile phone: 12 units were collected in March. So far this month, I have received 2 washing machines, 2 refrigerators, and 1 TV......
This is not a laborious move, but also requires "brain power". The value of home appliances is related to internal compressors, hard disks, components and other parts.
"At first, I didn't understand it, but I recycled a lot, and the company also trained me often, and I gradually became familiar with waste household appliances. Master Luo said, "For example, the components of the TV screen are more recyclable than the shell. ”
Second stop: sorting
At the door of the service station, Luo Dahai and his colleagues moved the recycled waste into the carriage one after another. At the headquarters of Zhejiang Huge Waste Management Co., Ltd., trucks carrying waste have been driven into the sorting warehouse. After weighing and unloading, the master registers the information of waste household appliances into the warehouse and moves it to each cargo frame.
In the factory, a row of racks is divided into categories to put all kinds of waste household appliances, washing machines have the difference between wave wheels and rollers, air conditioners are placed according to hangers and cabinets, and TVs have old-fashioned TVs and LCD screens......
Wang Wenqin, director of the Renewable Resources Centre, said that on average, about 1,500 waste electrical appliances are recycled every month, of which more than 98% are four machines and one brain (referring to refrigerators, washing machines, air conditioners, TVs and computers). "There is also a seasonality in the recycling of household appliances, especially in summer, and the demand for refrigeration equipment updates such as air conditioners and refrigerators has increased, which is also related to more e-commerce promotions in June. ”
On the company's big data information screen, more detailed data records the life updates of "residents": 29 electrical appliances were received on April 17, and as of 15:00 on April 17 this year, the company had recycled 1,195 televisions, 732 microcomputers, 92 air conditioners, 701 refrigerators, and 895 washing machines.
And some of the old models recovered also brought the staff the fun of "treasure hunting". There is an exhibition area of old objects in the company's headquarters, where many "antiques" are placed: rotary dial telephones, black-and-white televisions, typewriters, antique video cameras...... As renewable resources, they have limited value, but they are long-lasting.
Third stop: dismantling
After sorting, waste spinning and waste plastics flow to garment companies, plastic products companies, etc. Large appliances are sent to a specialized dismantling company. Warehousing, weighing, and traceability codes...... large household appliances collected by "Brother Tiger" appeared in the dismantling plant of Zhejiang Shengtang Environmental Protection Technology Co., Ltd.
Shengtang Environmental Protection divides the entire dismantling plant into several dismantling lines such as TVs, refrigerators, washing machines, etc. "Dismantling is to 'squeeze' the residual value of each home appliance part, so it is necessary to carry out 'refinement' to the end. Dong Lei, deputy general manager of Shengtang Environmental Protection, said, "In our factory, more than 200 employees are assigned to work in 19 different positions, as small as a plastic shell. ”
The detailed division of labor brings extremely high operational efficiency. According to Dong Lei, the dismantling time of a 25-inch LCD monitor is about 220 seconds, and the fastest dismantling is the refrigerator, "We have introduced a full set of equipment from Germany, and in less than 50 seconds, a complete refrigerator can be decomposed into reusable materials such as copper, iron, and plastic." ”
In the case of abundant front-end recycling, Shinetech Environmental Protection can dismantle about 10,000 sets of waste household appliances every day, and the dismantled parts are classified into more than 200 categories of reusable materials, which flow to the next level of deep processing enterprises.
Is it enough to dismantle quickly and accurately? Far from it. The dismantling of waste household appliances has both economic and social value, and the latter can be reflected in the recycling and dismantling of hazardous waste.
Dong Lei said that old electronic components also have reusable elements, such as precious metals on circuit boards. However, circuit boards are often accompanied by lead-acid, resin powder and other environmentally harmful substances, and manufacturers without relevant qualifications may let harmful substances enter the environment when reducing and refining.
"In our eyes, there is a place for every old appliance. Dong Lei said, "Our task is to intercept hazardous waste in the dismantling process and hand them over to reliable deep processing enterprises." ”
Stop 4: Regeneration
Accurate classification is related to the reuse rate of the dismantled materials by downstream deep processing enterprises to ensure that the recycled materials go to the right place in the right way.
Dong Lei mentioned the common motors in household appliances, "There are aluminum and copper, and the mixing of the two metals will affect the economic benefits and reduce the production efficiency of downstream enterprises, which requires the employees on the dismantling line to have a high level of professionalism." ”
Anhui Tongling Fumao Renewable Resources Utilization Co., Ltd. is a partner of Shinetech Environmental Protection for many years. Every month, Tongling Fumao will purchase about 5000~6000 tons of waste refrigerators and air conditioning compressors. Mr. Wang, the company's manager, said with a smile: "When it comes to our link, we don't count it by one, but by the ton." ”
In line with the rhythm of the seasonal change of household appliances, from June to August every year, it is also the peak period for the company's purchases. Before the compressor enters the factory, its parts have been destroyed according to the regulations to avoid entering the second-hand market. Instead of compressors, they see cut metals such as copper, iron, aluminum, etc.
The value of the metal is self-evident, and after fine dismantling, it either flows to the trading end, or to the copper factory, aluminum factory, iron factory, etc.
Mr. Wang gave an example of copper, "After the copper factory buys it back, it will be reprocessed to produce coarse copper blocks, or it can be finished into copper rods, copper plates, and copper strips, and then it can enter the industrial field." ”
Every household appliance will be abandoned, some will consume their life in one household, and some will be circulated in several places to witness different lives. Seemingly lifeless household appliances also carry stories and emotions: it may come from your first salary, or witness a new marriage, or a child's childhood friend, or the companionship of elders in their later years......
But don't worry, because of the existence of the resource recycling system, part of the new home appliances may come from the "old friend" who left. After leaving home, waste household appliances can also be reborn in the wonderful journey of recycling.
