[Author] This edition writes "International Herald Tribune" reporter Guo Yina He Degong Chen Rui

Slightly dirty clothes, with a hoarse voice, riding a cart piled with goods back and forth in the alley, shouting: "Take home appliances! Refrigerator, color TV, washing machine..." or a piece of hard paper shell standing up at the gate of the residential courtyard with the words "Recycle Home Appliances" written on it ". This is a lot of people's impression of home appliance recycling.

However, if you go to Japan's Panasonic Home Appliance Recycling Company (PETEC), you will find that the original home appliances can also be recycled. Recently, the reporter walked into PETEC and found that the waste products were not born as waste products after exploring the various decomposition procedures of household appliance recycling. It depends on whether you want to use your brain and give it a second life.

Visit: Panasonic Recovered ≈ 160000 Vehicles and 94 Planes in 10 Years......

The "International Herald Tribune" article is rich in Japanese wine called "Tan" in the beautiful and quiet city of Kadong, Hyogo Prefecture, Japan. Many fields are planted with rice for winemaking. In front of a golden wheat field sits Panasonic Appliance Recycling Company (PETEC).

"There used to be people who would say that building a home appliance recycling plant in such a beautiful, wine-rich place wouldn't damage the ecological environment?" PETEC President Tomita said, "but we have gained recognition from our neighbors by constantly introducing and communicating with local residents. PETEC has been able to blend in with its surroundings." Futian said that even trucks transporting waste household appliances have been "packaged": the trucks are covered with covers to prevent others from seeing that they are vehicles transporting waste household appliances and will not block others.

"Take it from the commodity and use it from the commodity"

"Take it from the goods and use it for the goods" is the slogan of PETEC. So, waste is how to turn waste into treasure here?

Entering the production workshop of PETEC, the reporter saw a TV set walking in "intact". After passing through layers of passes, the reporter went out in pieces. Among them, analog TV is more.

This year is the year that Japanese television communications changed from analog signals to digital signals. Before and after August, when the signal was officially switched, many consumers focused on purchasing new TVs. Unprecedented busy not only home appliance retailers, and recycling manufacturers.

Next to the first "manual disassembly" production line in the PETEC workshop, workers in blue overalls, white helmets and masks on their faces were working manually to disassemble each TV set. When split, the glass tube inside the TV is exposed.

Next is the second procedure-separating the picture tube. The staff will take out the panel glass in front of the TV and the funnel glass in the back.

Subsequently, the reporter saw a large pink broken washing machine, issued a rumbling sound. Both the panel glass and the funnel glass taken out in the previous process are transferred to this machine to be crushed and cleaned. Pieces of broken and high-purity small glass slide down the conveyor track into the recycling bin after the "shower. Recycling bins are not the end of the line; their ultimate destination is to be shipped to overseas CRT production plants to be used as materials to re-produce new tubes.

Air conditioning's division

On the second floor of PETEC, the reporter also saw several "recovery experts". The first is the magnetic selection machine for recycling iron, copper and aluminum in the air conditioner. After the heat exchanger of an air conditioner is disassembled and crushed, the iron, aluminum, copper and plastic that can be recycled are mixed together. How to achieve rapid separation through the machine, respectively, recycling?

This machine first through the internal device of the magnet to screen out two categories, namely iron and non-iron. Non-iron also includes copper, aluminum and plastic. In the next step, the separation is further carried out by permanent magnets operating at high speed. According to physical principles, a high-speed permanent magnet generates an alternating magnetic field. Copper and aluminum entering the magnetic field will generate eddy currents, thus forming far-force and jumping into a box placed far away in advance. However, the plastic will not be affected by the magnetic field and will gently fall into the box closer to the separator. These two steps are not enough. Finally, there is a distinction between copper and aluminum. This is to be operated by vibrating the specific gravity selection machine.

A blower is set at the bottom of the vibrating machine to blow upward. As copper is heavy and aluminum is light, the aluminum entering the selection machine will float into the special box for aluminum recycling as soon as the wind blows, while the copper with heavier quality will slowly climb in the inclined direction and climb into the special box for iron recycling under the action of continuous wind.

Big account and small account

These technical principles are seemingly simple, but they are the magic weapon for rapid recycling developed by PETEC. As of April 2011, PETEC has processed more than 8 million household appliances. Of the recovered resources, nearly 130000 tons of iron, 20000 tons of copper and more than 10000 tons of aluminum have been recovered. If this iron is used to make cars, it can make about 160000 amount of cars. 20000 tons of copper is equivalent to 80 Nara Buddhas, while the recycled aluminum can make 94 Boeing 747 aircraft.

PETEC not only calculated this big account in the past 10 years, but also calculated every small account clearly. According to statistics, 14.3 kilograms of glass can be obtained from a waste TV set, which can be made into 68 exquisite glasses; a washing machine contains about 10.8 kilograms of plastic, which can make 58 double-layer lunch boxes. In a refrigerator produced in 1982, 50% is iron, 40% is plastic, and 3% is aluminum and 4% is copper. It can be said that PETEC is not only a recycling factory, but also a diverse treasure mine.

Mirror: Consumers Should Paste for Recycling

"International Herald Tribune" article In China, when consumers eliminate home appliances, they will find a higher-priced waste recycling buyer. But in Japan, consumers are looking for a buyer with a lower recycling price.

This is because in 1998, the Japanese government enacted the re-commercialization law for specific household machines (also known as the household appliance recycling law). In the law, home appliance consumers are also called "emitters" in Japan ". Japan's Home Appliance Recycling Law stipulates the division of responsibilities of the three parties, in which home appliance retailers bear the obligation of collection and handling, manufacturers bear the obligation of recycling, and the emitters who use home appliances bear the corresponding costs, so as to promote the formation of a circular society.

For example, at Panasonic's recycling points, consumers have to pay 2835 yen (about 236 yuan) for a 16V LCD plasma TV set, 4830 yen for a 171-litre refrigerator, 2520 yen for a washing machine and 2100 yen for an air conditioner.

"This kind of consumer handling of home appliances has to be upside down, which makes many Chinese who visit here feel incredible." PETEC President Tomita said. In fact, in some other countries, consumers seem to make money when selling home appliances, but merchants have already added all the recovery costs to the selling price of goods.

The Household Appliances Recycling Act also specifies the statutory recycling rates for various household appliances. The recovery rate is calculated by dividing the weight of the valuable item by the total mass of the scrap and multiplying it by 100.

Before 2008, the recycling objects of the household appliance recycling law only included televisions, refrigerators and freezers, washing machines and household air conditioners, and the legal recycling rates should reach 55%, 60%, 65% and 70% respectively. After 2009, flat-panel TVs (plasma, liquid crystal) and dryers were added, and the recovery rates should reach 50% and 65% respectively.

In recent years, with the continuous research and development and improvement of recycling technology by various home appliance manufacturers, the recycling rate of TV sets has reached 85% in 2010, compared with 73% in 2001.

Depth: by recycling achievements resource power

"International Herald Tribune" article In recent years, the concept of urban mines has gradually penetrated into the hearts of Japanese people.

Japan's independent administrative legal person material research institute speculates that the amount of metal extracted from recyclable goods in Japan can make Japan comparable to several resource-rich countries in the world.

Specifically, 6800 tons of gold, equivalent to 16 per cent of existing global burial, and 60000 tons of silver, equivalent to 22 per cent of burial, could be recovered from these commodities. These figures do not include Japanese exports of home appliances abroad. However, this number may increase in the future. This year, Panasonic, together with another Japanese company, will cooperate with a resource recycling company in Hangzhou to jointly set up a resource recycling company to recycle five kinds of waste household appliances in Zhejiang Province and decompose them.

Although mobile phones rich in rare metals have not yet been included in the mandatory recycling scope of the Home Appliance Recycling Law, the Ministry of Internal Affairs and Communications of Japan, which is in charge of the communications industry, has already made specific arrangements for mobile phone recycling at a research meeting held in 2009. This includes letting 70% of consumers know about mobile phone recycling activities in 2012. In 2012, the metal recovery rate in recycled mobile phones will be increased from the current 60% to 70%. The independent target of mobile phone recovery rate for mobile phone manufacturers is set at 30%.

There are no mobile phones on PETEC's current recycling catalog. However, PETEC President Tomita said that if mobile phones are added to the recycling targets of the Home Appliance Recycling Law in the future, they will also actively recycle them according to law.

Last month, Japan's Ministry of the Environment announced the latest recycling system for small appliances. The recycling list includes 45 categories of goods such as digital cameras. In the past, small household appliances were mostly landfilled in Japan. However, according to the calculation of the Ministry of the Environment, if the recovery rate of mobile phones, digital cameras and computers reaches 30%, the production cost can be basically balanced by obtaining rare metals from them. If a 30% recovery rate is achieved, 54000 tons of useful metals will be obtained, worth 16.5 billion yen (100 yen is about 8.29 yuan). According to estimates, this requires local governments to add about 2 billion yen per year in collection and classification costs. It is reported that for small household appliances, the government does not charge back to the emitters in principle. The system is expected to be implemented in 2014.

Japan, in the eyes of many people seems to be synonymous with extreme lack of resources. But it is from this sense of crisis that the combination of Japanese officials and people is constantly accelerating the progress of turning waste into treasure. While other countries are still dreaming with the label of vast land and abundant goods, Japan is already quietly acting.
