How toxic is waste batteries

　　How toxic is waste batteries?

　　 Professor Nie Yongfeng of the Department of Environmental Science and Engineering of Tsinghua University clearly stated that ordinary dry batteries do not contain cadmium, lead, and arsenic, but they are rich in cadmium, lead and arsenic. A very small amount of mercury is added to the mercury contained in batteries every year in the country, and no beneficiation company contains more mercury in the waste water discharged a year, and its toxicity is even negligible. What's more, China completed the mercury-free battery production in 2006. .

　　Are ordinary dry batteries suitable for collection?

　　 Nie Yongfeng believes that nickel-cadmium batteries (rechargeable more than 500 times), lead-acid batteries Batteries (usually used in cars) need to be recovered. The toxic substances contained therein are of high quality and have a high recovery rate; while ordinary dry batteries have minimal impact on the environment, and secondly, recovery is uneconomical. From the perspective of environmental hazards, the collection of collections will cause greater environmental pollution, and each ton of dry batteries collected will probably cost several thousand yuan. The country has clearly pointed out that it does not encourage or initiate gatherings to collect and reclaim used batteries. The reason is that secondary pollution is more expensive.

　　How to dispose of used batteries?

　　 How toxic is it to discard used batteries? Cadmium seeps out and pollutes the land and water bodies, and eventually enters the human body and damages the liver and kidneys. It also causes the bones to become soft and deformed in severe cases. Waste car batteries are rich in acid and heavy metal lead that leaks into nature, which can cause soil and water pollution, which will eventually cause harm to people.

　　 We understand that mercury-free environmentally friendly batteries are now popular in the market! Compared to carbon batteries that pollute the environment, alkaline batteries do not contain harmful substances such as mercury and cadmium. Even if it is accidentally abandoned in the wild, it will not pollute water and soil due to mercury leakage. When purchasing, you only need to see if it is a mercury-free alkaline battery to know if it is an environmentally friendly battery.

　　Recycling waste batteries: The popularity of household appliances and the addition of varieties have caused the usage of batteries to increase dramatically. Mixed with waste batteries not only pollutes the environment, but also wastes it. The country’s annual battery consumption is 3 billion, and 740 tons of copper, 16,000 tons of zinc, and 97,000 tons of manganese powder are lost due to non-recovery. We should separate the used batteries from other waste and gather them for recycling.
