RECYCLING AND RECOVERY OF USED ZN-C PRIMARY BATTERY

In the last two decades, great work had been carried out in recycling the used batteries. In order to enhance the recycling of used batteries, several directives were introduced and followed by different countries. Used batteries contain majorly heavy metals which are considered as waste. These heavy metals are hazardous to the environment such as mercury, nickel, lead, cadmium, lithium and so on. The disposal of these heavy metals caused many environmental problems such as environmental pollution, global warming, and human health problems. This review paper deals with the disposal of used primary batteries such as Zn-C battery and the problems faced while disposing batteries. It is considered that recycling of used batteries is considered as an efficient way of disposing used batteries. Also, explained the re cycling and recovery process used in Zn-C batteries and the usage of the recovered materials in various applications.
