Plastic bottles are used as podiums, waste electrical equipment as MEDALS, and how green are the Tokyo Olympics?Japan responded like this
As of today, China has already won 53 MEDALS in the Tokyo Olympics!
But do you know what these MEDALS are made of?
According to CCTV,
The MEDALS in Tokyo are made from metals found in scrap.
Many athletes who won gold MEDALS at the Tokyo Olympics found that their MEDALS were made of electronic waste.
Japan's latest explanation came after many athletes and the media questioned it, stressing that the Games were a "Renaissance event" and that one of the themes was environmental protection.
However, it is worth mentioning that there are many materials in e-waste that can be reused, such as some metals, precious metals, rare metals and plastics.
Therefore, reasonable and prudent disposal and recycling of e-waste is necessary.
In line with the international Olympic Committee's philosophy and requirements of technology and environmental protection, as early as April 2017, Japan launched the "Urban Mine" project in preparation for the Olympic Games.
In 1988, "urban mine" was first proposed by Professor Michio Minamidou of the Research Institute of Mineral Processing and Processing of Tohoku University in Japan. It is vividly called "mine" because e-waste contains a variety of valuable metals and precious metals.
The plan is to take waste e-waste as mineral resources and recycle it in a planned way to obtain available resources.
Took more than two years of time, Tokyo organizers collected more than seventy thousand tons of waste household appliances and a total of more than six hundred mobile phone, not only promoted the public engagement for the games, and to extract from nearly 32 kg, 3500 kg of pure gold silver and 2200 kilograms of the material such as pure copper, good meets the need of production of Olympic MEDALS.
It is understood that the raw materials used in the MEDALS awarded by Japan to athletes from various countries are mainly metals extracted from mobile phones and other electronic products used by millions of Japanese people.
If it weren't for the cardboard beds in the Tokyo Olympic Village, people might not know that beds can be made of paper.
As far-fetched as it sounds, there are deeper reasons why the Olympic committee is doing this.
The Tokyo Olympic Organizing Committee regards the concept of sustainable development as "working together for a better future for the planet and people".
Under the principle of "doing better for the planet and for people", the organizing committee has used a lot of renewable energy and recyclable raw materials in the preparation of the Games, which may be the most environmentally friendly and green Games in history.
Even more surprising than the cardboard beds are the MEDALS and podiums, which can also be made from scrap material.
In the Olympic Village, hydrogen-powered cars have been put into use and a hydrogen-powered community has begun to take shape.
In order to implement the concept of environmental protection, Japan can do how "exaggerated"?
It's not just the cardboard beds. Discarded paper cups and plates from the Olympic Village will be recycled and turned into toilet paper.
At a recycling plant in The city of Fuji, Li Miao saw the process of making recycled products.
Waste paper from the village is first removed from impurities and ink, and then processed by a machine into finished toilet paper.
Waste water from the papermaking process is also treated to meet environmental standards before being discharged into the city's rivers.
"Our goal is to reuse or recycle 99 percent of everything we buy or borrow," said Yuki Arada, director of sustainability at the Tokyo Olympics organizing Committee.
Of course, items like containers should be recycled as much as possible, so paper containers are recycled after being used for meals and are used again as paper.
In addition, we have set a target of 65% of sports waste, such as finished drink bottles and leftover food, to be recycled.

"Scrap" podiums and "scrap" MEDALS
The Tokyo Olympic committee has announced that Japan will use 100% renewable energy and zero carbon emissions.
In order to achieve this goal, the Olympic committee has enlisted the Japanese people to help the environment.
"For the podiums, we asked citizens for detergent bottles, discarded bottles, etc., and with the help of P&G, we collected them from citizens and melted them down to make the podiums," said Yuke Arada, director of sustainability at the Tokyo Organizing Committee.
I'm sure the children who helped us will be very happy."
The Organizing committee is trying to get people to collect used plastics.
More than 100 podiums, a total of 45,000 kilograms, 1.5 million plastic items.
At 75 grams of co2 per plastic item recycled, the energy savings would be enough to light a home for 112 years.
Take hydrogen in a new way
Hydrogen energy plays a very important role in the environmental protection strategy of The Tokyo Olympics. It is an important carrier of low-carbon energy reform.
In the use of hydrogen energy in this field, Japan has the world's leading technology, the Tokyo Olympic Games has become a Japan to show the international community energy development technology achievements of the "hydrogen show"!
Li Miao, chief correspondent of Phoenix TV in Japan, learned from Yuki Arada, director of the Sustainable development department of the Tokyo Olympic Organizing Committee, that some of the torch will be fueled by hydrogen, which does not produce greenhouse gases or particulate pollution.
But there were some problems with the hydrogen-powered torch, such as the combustion mechanism. The flame produced by the hydrogen combustion is almost transparent, so the design team had to go to great lengths to "dye" the flame.
The Olympic village in Tokyo is also equipped with self-driving cars powered by hydrogen.
The hydrogen buses will run every five minutes during rush hours, with a maximum interval of 20 minutes, and they can run automatically for 24 hours, the staff said.
"Sustainability is one of the main pillars of the Tokyo Olympics," said Koji Arai, director of the Tokyo Organizing Committee's Office of Innovation Promotion.
Our goal is to emit no carbon dioxide, so we will use the hydrogen produced in Namie, Fukushima, to power a hydrogen car, which I think is one of the sustainable measures."
The Olympic Village, through which the buses travel, is already powered by hydrogen.
"We are also using hydrogen to generate electricity in the Olympic Village and for some of the dormitories," Said Yuki Arada, director of sustainability at the Tokyo Olympic Organizing Committee
Hydrogen power has been embedded in pipes for use in the Olympic Village after the Games, when it will be used as a regular house.
I think this is one of the characteristics of the Olympic Games."
The Olympic Village will be powered by hydrogen from a plant in Fukushima, Japan, which is the world's largest hydrogen manufacturing plant.
After the Games, the Olympic Village will be transformed into the world's largest hydrogen-powered community.
The 4,100 apartments will also be equipped with hydrogen fuel cells.
It will be the first community in Japan to put hydrogen stations, hydrogen pipelines and hydrogen fuel cells into full use.
According to the UN's e-waste report, one gram of gold can be extracted from 35 to 40 mobile phones.
The Tokyo delegation released a statement that it had extracted more than 30 kilograms of gold, 100 kilograms of silver and 2,700 kilograms of copper from nearly 80,000 tons of home appliances and 6.2 million mobile phones to make the MEDALS using new refining technology.
Japan is preparing about 5,000 gold, silver and bronze MEDALS for the entire Games, starting four years ago.
Over 700 days, tens of thousands of collection boxes were placed across the country.
About 90 percent of the local people in the area participated in the event, and many people left their unused electronic products in the collection boxes, including mobile phones, computers, digital cameras, electric shavers and computers.
Using environmental protection slogans, Japan fully mobilized the enthusiasm of the public to crowdfund Olympic MEDALS.
In other words, Japan does not need to take actual gold from the bank, but can extract some gold directly from electronics, which is literally "turning waste into treasure."
5,000 MEDALS needed at the Olympics
