Note! Do You Know How To Classify Used Batteries?

Date:May 15, 2019

In our daily life, the battery can be said to be one of the highest usage and rejection rates, but do you know the proper way to dispose of used batteries?


Some people say: "The battery can't be littered because it is very harmful to the environment."


Some people also said: "Isn't everyone throwing it? It's not too much harm!"


So, how do you deal with the used batteries at home?


People often say: "A button cell can pollute 600 cubic meters of water, which is equal to the amount of water a person can drink in a lifetime. One cell of the first one is rotten in the ground, which can make one square meter of land useless." However, the truth of the truth Is it really?

NO! NO! NO, the current battery has been considerably improved.


If it was before, it would not be too much to call the "disposable dry battery" in a section called "pollution bomb". However, with the development of science and technology, as early as 2005, these [disposable dry batteries] have gradually disappeared. Achieve low-mercury and mercury-free production!


The mercury content of 0.0001% is close to or even lower than the naturally occurring mercury content in uncontaminated soil. Therefore, the disposal of [disposable dry battery] has no effect on the natural environment. After being discarded, it can be mixed with domestic garbage or landfill.

So how do you put the waste battery in the end

This is about starting from its classification.

The batteries are mainly divided into the following categories:

Disposable dry battery

The most familiar dry batteries for flashlights and remote controls. The most common in the family is a variety of disposable batteries with different capacities such as No. 5 and No. 7.

Zinc-manganese batteries (also known as carbon batteries) and alkaline manganese batteries (alkaline dry batteries) mainly contain heavy metals such as iron, zinc and manganese, and also contain trace amounts of mercury, which is a toxic substance. More than a decade ago, due to production technology, the mercury content of ordinary dry batteries was relatively high, and if discarded at will, it would cause pollution to soil and water. However, since January 1, 2005, China has stopped producing and selling alkaline batteries containing more than 0.0001% of mercury. At present, the disposable dry batteries used in households use mercury-free and low-mercury technologies, which have little impact on the environment. So we can throw it into other garbage (yellow bucket) as ordinary garbage.


Button battery

Button battery for children's toys and electronic watches.

Button batteries are generally available in both rechargeable and non-charged versions, including 3.6V rechargeable lithium ion button battery (LIR series) and 3V rechargeable lithium ion button battery (ML or VL series); The charging includes 3V lithium manganese button battery (CR series) and 1.5V alkaline zinc manganese button battery (LR and SR series).

The button-type battery is made of stainless steel. It contains heavy metals such as mercury, manganese, cadmium, lead and zinc. If you dispose of the waste battery in nature, these materials will leak out when the outer metal is corroded. It breaks into the soil, penetrates into the groundwater with rainwater, and flows into rivers, lakes and seas to form serious pollution.


Cell phone battery

The phone battery used on the phone. According to incomplete statistics, at present, the number of mobile phones in China exceeds 1.3 billion, almost to the state of the average manpower. The environmental pollution of used mobile phone batteries cannot be ignored.

Abandoned mobile phones and batteries contain heavy metals such as gold, mercury, lead, and cadmium. If they are directly discarded or landfilled, heavy metals will directly pollute the soil and groundwater. When they are simply incinerated, the gases they produce will pollute the air and cause poisoning.


Lead-acid battery for uninterruptible power supply and motor vehicle battery

It is used in elevators, banks and other ups uninterruptible power supplies and as lead-acid batteries for motor vehicle batteries.

The lead-acid battery is mainly made of lead and its oxide, and the electrolyte is a sulfuric acid solution. If the waste lead-acid battery is not disposed of according to the regulations, the waste residue and acid solution generated by it will be extremely harmful to the environment. Therefore, it is listed in the “National Hazardous Waste List” and needs to be managed according to the relevant standards of hazardous waste. It is not allowed to transfer, collect or dismantle without authorization. Solution and disposal.


Therefore, the common disposable dry batteries are basically free of pollution risks, and can be directly put into other garbage cans as ordinary domestic garbage, but only for ordinary disposable dry batteries.


Button batteries, mobile phone batteries, and lead-acid batteries are all hazardous wastes and cannot be mixed with household waste. It needs to be recycled in time.

The main hazard of heavy metals in waste batteries


Mercury can dissolve in fat, causing central nervous system diseases in animals, teratogenic, causative, carcinogenic and even death;


Cadmium softens the bones, deforms the bones, and forms a natural fracture in severe cases, resulting in death;


Lead mainly causes anemia, neurological dysfunction and kidney damage, and inhibits the anabolism of hemoglobin;


Nickel dissolves in the blood, damages the central nervous system, causing vascular variability;

Since the harmful battery hazard is so big,

So how do we put it in our lives?

Button batteries, mobile phone batteries, and lead-acid batteries are hazardous wastes and should be placed in hazardous battery recycling bins for centralized recycling by workers.

 

Harmful batteries are so hazardous that they cannot be discarded at hand. Find ways to deal with it, environmental protection depends on everyone. It is the responsibility and obligation of each of us to care for the environment around us and to participate in the recycling and recycling of hazardous batteries. Personal behavior may be insignificant, but uniting the strength of each of us is enough to hold up a civilization, a civilization that coexists with nature, a sustainable civilization.
