Disposable Batteries’ Severe Impact on the Environment.
The increasing global demand for batteries is largely due to the rapid increase in portable power-consuming products such as cellular phones and video cameras, toys and laptop computers. Each year consumers dispose of billions of batteries, all containing toxic or corrosive materials. Some batteries contain toxic metals such as cadmium and mercury, lead and lithium, which become hazardous waste and pose threats to health and the environment if improperly disposed. Manufacturers and retailers are working continuously to reduce the environmental impact of batteries by producing designs that are more recyclable and contain fewer toxic materials. The global environmental impact of batteries is assessed in terms of four main indicators. These indicators further distinguish the impact of disposable and rechargeable batteries. Potential toxic risks are associated with emission of battery chemicals into aquatic ecosystems. Improper or careless handling of waste batteries can result in release of corrosive liquids and dissolved metals that are toxic to plants and animals. Improper disposal of batteries in landfill sites can result in the release of toxic substances into groundwater and the environment. Credit: Brut.
