Waste batteries turn waste into treasure.
Students pour waste batteries into the waste battery recycling bin.
"I'm really happy to take part in this environmental protection activity, because I know that these batteries are no longer homeless as before, and they can also turn waste into treasure!" District students in Grade Two of Xiaoyuan Middle School told reporters excitedly. On the special day of "Earth Day" yesterday, the "Environmental Action for Recycling Used Batteries" jointly sponsored by Guangzhou Environmental Protection Education Center was officially launched.
According to reports, the biggest difference between this battery recycling operation and the past is that the recycled waste batteries will not be handed over to the sanitation department for landfill treatment, but will be sent to a waste recycling company in Panyu District for crushing, sorting and forging to become useful metals for reuse. This indicates that the recycling of waste batteries in Guangzhou has achieved an important transformation from "alkali damage" to "resource utilization".
The "environmental protection action of recycling used batteries" will be carried out in schools in the whole city at first. The first batch of schools in Haizhu District 100 will be selected as pilots, and then spread to the community and gradually spread throughout the city. A waste recycling company in Panyu District, which is responsible for recycling waste batteries, will also set up special waste battery recycling bins in the above areas for a long time, and send dozens of vehicles to recycle waste batteries discarded by citizens.
According to Chen Guoan, the chief engineer of a recycling company in Panyu District, taking the battery in 4 yuan as an example, the value of recovered useful metals can reach 3.2 yuan, which is equivalent to 80% of the battery cost. According to reports, at present, Guangzhou consumes about 500 million batteries every year, equivalent to about 2,500 tons, of which 80% are discarded after use.
How to turn waste batteries into treasure?
It should be recycled. There is nothing to use.

When will waste batteries become valuable (discussion)
Nowadays, with the enhancement of people's awareness of environmental protection, there are more and more activities to recycle waste batteries, and many people turn over waste electricity.
As a conscious action. However, the recycled waste batteries have encountered the embarrassment of "homelessness". Go to Jinan ginza
Take the shopping mall as an example. Since 1998, shopping malls have the obligation to recycle used batteries. So far, it has recovered more than100000 parts, except a part.
Except for the treatment trial in an enterprise, the rest are still stored in the shopping mall. It is reported that there is no place in such a large Shandong province.
Enterprises that operate waste batteries are quite worrying.
We know that waste batteries are a serious pollution source, especially the high content of mercury and lead, which directly threatens people's health.
Healthy. Because people don't know enough about this, it is very serious to discard waste batteries at will, and some waste batteries are treated as garbage.

Take recycling used batteries as a major event, so that used batteries can "precipitate" in time and return to their parents' homes as soon as possible. no
Then, only paying attention to the production of batteries, but not to their recycling, will cause waste of resources and long-term harm to the environment.
Long-term injury.
I hope people can understand this and do a good job in recycling used batteries, which is not only the need to save resources.
Yes, it is also the proper meaning of the theme of "green consumption".

How to deal with waste batteries correctly
The increasing garbage production is overloading the planet we live in, and the endless public hazards and "garbage siege" have sounded the alarm for us. How to realize harmlessness, reduction and recycling has become a top priority. "Dislocation of resources" is a new understanding of garbage in recent years. The implementation of garbage classification will make the best use of recyclable garbage and turn waste into treasure.
In terms of volume and weight, waste batteries are insignificant in domestic garbage, but their harm is very great. Batteries contain heavy metals such as mercury, cadmium and lead. Mercury is very toxic, and lead can cause nervous disorder and nephritis. Cadmium mainly causes kidney injury and bone diseases-osteoporosis, rickets and fractures. If waste batteries are buried together with domestic garbage, heavy metals may pollute groundwater and soil over time.
The usage of batteries in our life is increasing rapidly, and it has penetrated into every corner of our life and work. Walkman, BP machine, mobile phone, camera, calculator. At present, the national battery consumption is around 7 billion. It is predicted that by 2000, the battery consumption of BP machine alone will reach 65.438+0.55 billion. If these batteries are not handled properly, they will directly or indirectly endanger people's health. Implementing and advocating the classified collection of used batteries has been recognized by more and more people, and has received more and more attention, support and participation-instead of dispersing pollution, it is better to treat it centrally.
Starting from me and starting from every little thing around us is our motto. Caring for the surrounding environment and participating in the classification and recycling of used batteries is the responsibility and obligation of each of us. Individual behavior may be insignificant, but the strength that unites each of us is enough to support a civilization, a civilization born out of nature and a sustainable civilization.
1. composition of battery: composition of dry battery and rechargeable battery: zinc sheet (iron sheet), carbon rod, mercury, sulfate and copper cap; The battery is mainly composed of lead compounds. For example, 1 waste zinc-manganese battery weighs about 70g, including 5.2g carbon rod, 7.0g zinc skin, 25g manganese powder, 0.5g copper cap and 32g others.
Second, the harmfulness of waste batteries: the harmfulness of waste batteries is mainly concentrated on a small amount of heavy metals, such as lead, mercury and cadmium. These toxic substances enter the human body through various channels, and long-term savings are difficult to eliminate, damaging the nervous system, hematopoietic function and bones, and even causing cancer. Lead: diseases such as nervous system (neurasthenia, numbness of hands and feet), digestive system (dyspepsia, abdominal cramps) and blood poisoning. Mercury: Mental state change is the main symptom of mercury poisoning. Rapid pulse, muscle tremor, oral and digestive diseases. Cadmium and manganese: mainly harm the nervous system. 3. Ways for waste batteries to pollute the environment: The components of these batteries are sealed inside the battery box during use and will not affect the environment. However, after long-term mechanical wear and corrosion, heavy metals, acids and alkalis will leak out, enter the soil or water source, and enter the human food chain through various channels. The process is briefly described as follows: pool soil microorganisms, animals, circulating dust, crops, food, human nerve deposition.
Heavy metals ingested by other water plants and food-borne organisms from the environment can accumulate in thousands of higher organisms step by step through the biomagnification of the food chain, and then enter people's bodies through food and accumulate in some organs to cause chronic poisoning. Water disease in Japan is a typical case of mercury poisoning. 4. Other manifestations of the harm of waste batteries: At present, the treatment of domestic garbage in the world is mainly sanitary landfill, composting and incineration. The pollution of waste batteries mixed with domestic garbage in these three processes is reflected in landfill: the heavy metals of waste batteries pollute water and soil through infiltration. Incineration: waste batteries corrode equipment at high temperature, and some heavy metals volatilize in the fly ash of incinerator, causing air pollution; Heavy metals accumulate at the bottom of the incinerator, polluting the ash. Composting: The high content of heavy metals in waste batteries leads to the decline of compost quality. Reuse: reverberatory furnace metallurgy is generally used. Although the process is easy to master, the recovery rate is only 82%, and the rest of the lead appears in the form of gas and dust. At the same time, sulfur dioxide in the smelting process will enter the air, causing secondary pollution and directly endangering the health of operators.
Harm of waste batteries: Mercury discarded from natural batteries will slowly overflow from the batteries, enter the soil or water source, and then enter the human body through crops, damaging the human kidneys. In microorganisms, ......
How are used batteries recycled?
How to recycle used batteries abroad? Nomura Company in Hokkaido, Japan buys 6.5438+0.3 million tons of waste batteries from all over the country every year, accounting for 20% of the national waste batteries. Among them, 93% were collected by non-governmental environmental protection organizations, and 7% were collected by various manufacturers. In the past, mercury was mainly recycled, but at present, batteries in Japan no longer contain mercury, so we mainly recycle the iron case of batteries and the "black" raw materials inside, and develop and manufacture secondary products, such as one of which can be used to produce TV picture tubes. German consumers are required to send all kinds of waste batteries, such as dry batteries and button cell, to shops or waste recycling stations for recycling. Stores and waste recycling stations must unconditionally receive waste batteries and hand them over to manufacturers for recycling. Waste recycling stations and manufacturers generally only recycle batteries containing toxic chemical components such as cadmium and mercury, while 90% of pugan zinc-carbon batteries and aluminum-magnesium batteries are buried or burned as domestic garbage. The United States has the most detailed legislation on environmental management of waste batteries. Not only has a perfect waste battery recycling system been established, but also a number of waste battery treatment plants have been established. At the same time, we will persistently publicize and educate the public, so that the public can consciously support and cooperate with the recycling of used batteries. = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = Waste battery pollution can not be ignored. With the improvement of people's living standards and the development of modern communication industry, people have more and more opportunities to use batteries, such as mobile phones, pagers, walkman, pocket radios and so on. In the future, there will be more waste batteries. However, although people have paid more and more attention to the protection of natural ecological environment in recent years, and achieved certain results in the treatment of environmental pollution such as water pollution, air pollution and white pollution, the pollution of waste batteries has not attracted enough attention. According to relevant data, a 1 battery rotted in the ground, which can make the soil of 1 m2 lose its use value forever; A button cell can make 600 tons of water undrinkable, which is equivalent to a person's lifetime drinking water. Among the five substances that pose the greatest threat to the natural environment, batteries contain three kinds: mercury, lead and cadmium. If waste batteries are mixed with domestic garbage and buried, mercury and heavy metals will seep into soil, pollute groundwater, and then enter fish and crops, destroying human living environment and indirectly threatening human health. How to dispose of waste batteries in time and safely has become increasingly prominent in front of people. Once the human body absorbs these heavy metals, what diseases will occur? According to experts, mercury is a highly toxic heavy metal, which has great destructive power to the central nervous system of human body. The Minamata disease that shocked China and foreign countries in the 1950s in Japan was caused by mercury pollution. At present, the mercury content of mercury-containing alkaline dry batteries produced in China is 1-5%, and that of neutral dry batteries is 0.025%. China's battery production consumes dozens of tons of mercury every year. Cadmium is easy to cause chronic poisoning in human body, and the main symptoms are emphysema, osteomalacia and anemia, which is likely to paralyze human body. Lead is the most difficult to excrete after entering the human body, which interferes with renal function and reproductive function. At present, the annual output of batteries in China exceeds 654.38+08 billion, accounting for more than 30% of the world's total battery output, and the annual consumption reaches 7-8 billion, but the recovery rate is less than 2%. Recycling batteries is awkward. Because people don't know enough about the pollution of used batteries, it is very serious to discard them at will. Whether in cities or villages, used batteries can be seen everywhere. It is understood that Beijing consumes more than 6,000 tons of batteries every year. Although the recycling of used batteries has attracted the attention of relevant departments in recent years, designated recycling units have been designated and recycling points have been set up in some high-density population areas such as schools, shopping malls and residential quarters, but the results have been minimal. Since 1998, Beijing Garbage Collection Center has recovered more than 400 tons of used batteries, and the recovery rate is only 1.7%. A large number of waste batteries were discarded. From May 65438 to May 1998, Shanghai began to recycle used batteries, and the recycling points of used batteries are also increasing year by year. Up to now, the city has set up 4,000 or 5,000 collection points for waste batteries, and * * * collects more than 0/00 tons of waste batteries/kloc, but this is far from the annual output of about 3,000 tons of waste batteries in the city. Three middle school students in Hangzhou used questionnaires, interviews, literature review, etc. to complete the investigation report of "Investigation and Research on the Status of Waste Battery Recycling" within a few months. The conclusion is that the recovery rate of waste batteries in China is only 1. ......
Turning waste into treasure, waste utilization
"Waste utilization [1]" in life!
Dry batteries that can't be used can be revived with a little effort. The method is extremely simple. Just rub it on your hands, feet or clothes for a while. This "revived" battery once made an alarm clock run for two weeks. Speaking of it, the principle of the battery is to generate current by chemical reaction. The battery is dead, but the current is not smooth. Even though the surface looks lifeless, there are still many components inside that have not yet produced chemical reactions. Therefore, as long as it is rubbed for a moment, the heat generated by friction warms the inside of the battery, which can help the residual components in the battery to produce a chemical reaction smoothly.
