What should I do with used batteries? How to dispose of waste batteries

Although there are special personnel and factories to waste batteries, but the overall is not ideal, harmful waste battery disposal is still a problem, it is recommended that you use mercury-free environmental protection batteries or rechargeable nickel-metal hydride batteries.

There are trash bins for old batteries, you just throw them in there! Pay attention to the environment!

Put it in a special ** box.

There are ** boxes at the entrance of the community, so it's good to still go in.

There are dedicated trash cans, which can't be **.

There are dedicated bins for batteries.

At the entrance of the community, there are special boxes or barrels in the company.

There are three ways to dispose of waste batteries: solidification and deep burial, classified delivery, and utilization.

1. Curing and deep burial.

In places where the state stipulates that waste batteries can be landfilled, the batteries are first wrapped in plastic bags or cartons, and then a large pit is dug to bury the waste batteries.

2. Classified delivery.

There are many imitation waste batteries at home, and we should hand it over to the sub-district office where we are located for disposal.

3. Utilization.

Put the waste batteries in the trash can of the waste battery, wait for the sanitation workers to come and deal with it, and then make reasonable use, different batteries should be disposed of separately, and the dry battery and rechargeable battery should be separated.

The most used industrial battery in China is lead-acid battery, which accounts for more than 50% of the total cost of the battery, mainly using pyrometallurgical and hydrometallurgical processes and solid-phase electrolytic reduction technology. The shell is plastic, which can be recycled, and basically no secondary pollution.

The hazards of waste batteries

When the chemicals inside the battery are completely reactive, the battery can no longer be powered and becomes a waste battery, which is usually thrown away and bought with a new one. Most people would say that this is quite normal. But they didn't expect that even with that gesture, they were also destroying their home, the earth.

Batteries don't look that destructive, but you can't look at all the surface. Waste batteries contain a large amount of heavy metals such as mercury, cadmium, manganese, lead, etc.

When the surface cortex of waste batteries is corroded in the sun and rain, the components in it will penetrate into the soil and groundwater, and it is not good for people to eat crops produced on polluted land or drink polluted water.

At present, there are 4 main treatment methods in ChinaManual sorting, dry, wet and dry-wet.

1.The use of manual sorting is to classify the waste dry batteries first, manually sort out carbon rods, copper caps, zinc batches and various residues, and treat them with corresponding methods, this method is simple and easy, but the use of labor is more, and the economic benefits are poor.

2.The so-called dry method, also known as smoke method or fire method, is to classify and screen waste dry batteries, crush, and then put them into the furnace to roast at 600-800 degrees, extract mercury after condensing the discharged gas, and then put the roasting residue into the rotary kiln at 1100-1300 degrees for low fever, from the flue gas ** zinc in the dry battery, if further ** other substances, equipment needs to be added.

3.The so-called wet method is to classify and crush the dry battery, put it in the leaching tank, add dilute sulfuric acid for leaching, and then filter to extract metal zinc from the filtrate, and then further extract manganese from the remaining sludge after the filter residue is separated from the copper cap iron sheet. This method can use the equipment and technology of the existing wet zinc smelting plant to make the best use of waste dry batteries.

4.Dry and wet method is to combine the advantages of dry and wet process, first use the roasting method **mercury and part of the zinc, and then use the method of leaching and electrowinning **manganese and residual zinc. Using this method, the first effect is good, but the process is more complex and the cost is higher.

In the past two years, the impact of waste batteries on the environment has become one of the most hot topics in China. Some reports say that batteries are very polluting to the environment, and one battery can pollute 60,000 cubic meters of water.

Some even say that waste batteries can cause hazards such as Minamata disease in Japan with the disposal of domestic garbage, and there is a No. 5 waste battery can make a square meter of land wasted, etc., these reports have caused great repercussions in the society, and there are many people and groups who love environmental protection to carry out or participate in the activities of waste batteries.

Scientific studies have shown that a button battery can pollute 600,000 liters of water after being discarded into nature, which is equivalent to the water consumption of a person's lifetime, and China consumes 7 billion such batteries every year.

It is understood that 96% of the batteries produced in China are zinc-manganese batteries and alkaline manganese batteries, and their main components are manganese, mercury, zinc and other heavy metals. Whether the waste battery is in the atmosphere or buried deep underground, its heavy metal components will overflow with the leachate, causing groundwater and soil pollution, and will seriously endanger human health over time. In 1998, mercury, cadmium, zinc, lead and chromium were designated as hazardous wastes in the National Hazardous Waste List.
