Ordinary batteries will no longer pollute the environment

"Can't you throw the waste battery casually? Out."@ CCTV news released this microblog on the 13th. The environmental protection department also said that household batteries have reached the national technical requirements for low mercury or mercury free, and can be scattered with daily household garbage without centralized and unified recycling. However, it should be noted that lead-acid batteries and nickel cadmium batteries such as button batteries and electric vehicle batteries still need to be recycled.
In a random interview yesterday, the reporter found that only one of the 10 citizens knew about it.
Environmentalists can't believe it
Mr. Nie lives in Nanping Shanghai city. Seven or eight years ago, he saw a message on the Internet that the pollution caused by a small No. 5 battery can destroy 1 square meter of soil. Since then, he has a habit of collecting waste batteries. But how to deal with the collected waste batteries has always been a difficult thing. Sometimes, the waste batteries have melted into water, and it is difficult to find a place to recycle them. To this end, Mr. Nie also contacted Chongqing solid waste management center. The other party told: ordinary No. 5 and No. 7 batteries can be directly thrown into the dustbin.
"Won't this pollute the soil and the environment?" Mr. Nie decided to continue collecting waste batteries.
It could have been garbage 10 years ago
In fact, as early as 10 years ago, ordinary batteries could be put together with household garbage. On October 9, 2003, the State Environmental Protection Administration issued the technical policy for the prevention and control of waste battery pollution, which pointed out that at present, in the absence of effective technical and economic conditions for recycling, the centralized collection of waste batteries that have met the national requirements for low or no mercury is not encouraged. "Discouragement" is mainly aimed at ordinary citizens.
On December 31, 1997, the China Light Industry Federation, the State Environmental Protection Administration and other nine national ministries and commissions jointly issued the provisions on limiting the mercury content of battery products. The standard for low mercury is that the mercury content in the battery is less than 0.025% of the battery weight, and the standard for no mercury is less than 0.0001% of the battery weight. From January 1st, 2002, it is forbidden to sell batteries higher than the low mercury standard in the domestic market, and from January 1st, 2006, it is forbidden to sell alkaline zinc manganese batteries higher than the mercury free standard.
The treatment method shall be subject to the battery label
People say that waste batteries are polluted, mainly because they contain cadmium, mercury and lead. These three heavy metals are highly toxic and remain in the environment for a long time. They will also enter the human body through the food chain, causing chronic poisoning.
At present, the single battery products sold in the market at home and abroad must be marked with mercury content. Just look at the mercury content of the battery, you can know whether it is an environmentally friendly battery and whether it can be thrown into the garbage can.
At present, our common batteries fall into six categories:
1、 Lithium battery, used for mobile phone batteries, etc., with negligible heavy metal content, can be put in with domestic waste.
2、 Alkaline batteries, such as No. 1, No. 5 and No. 7 batteries for household use, have no or low mercury and can be put with household garbage.
3、 Nickel metal hydride batteries are used in hybrid vehicles, children's toys, etc. the content of heavy metals can be ignored and can be put with domestic waste.
4、 Nickel cadmium battery, used in low current cordless phones and electric toys, contains a large amount of heavy metal cadmium, which needs to be recycled.
5、 Lead acid batteries, electric vehicle batteries, etc. contain a large amount of heavy metal lead, which needs to be recycled.
6、 Button batteries, used in electronic equipment, etc., allow the existence of a small amount of mercury and need to be recycled.
