If able to decompose, they can take over 100 years to fully decompose*. Another consideration of throwing away batteries is safety. Some battery types, including lithium-ion, have a higher potential for a thermal runaway event – if not handled properly.

Since 2015, developing nations like Vietnam have increased their battery processing capacity as global demand for batteries has grown. The process for recycling batteries often leads to toxic metals being introduced into the environment. In many of these nations, there are little protections available for workers working with the batteries.
The process for recycling dry and alkaline household batteries follows the same principle as the process for the recycling of NiCd batteries. In such process, household batteries are milled in the shredder and the shredded materials are screened. The coarse fraction is mainly composed of metals and is separated from the process.
Battery recycling is a recycling activity that aims to reduce the number of batteries being disposed as municipal solid waste. Batteries contain a number of heavy metals and toxic chemicals and disposing of them by the same process as regular household waste has raised concerns over soil contamination and water pollution.
Unfortunately, there is no relation between the size or shape of batteries and their composition. Researches have occurred in several laboratories in order to develop new recycling processes for used batteries or, in certain cases, new treatments to allow a safe final disposal. 2.
