Batteriesmay contain toxic metals such as cadmium, mercury and lead, so their disposal must be controlled. Brazil was the first country in LatinAmerica to regulate the disposal and treatment of batteries. Limits were established on the concentration of heavy metals within batteries,so that they could be disposed along with domestic waste. Since batteries are products used broadly, it is very difficult to control theirdisposal. In order to have an efficient collection, the population must be engaged, and that can only happen if they are informed aboutthe laws and regulations regarding the subject, as well as the importance of disposing of batteries with higher concentrations of heavymetals or toxic substances separately from domestic garbage. Around the world, there are some long-established recycling processes forbatteries. In Brazil, automotive (lead–acid) batteries have been recycled for several years, whereas the recycling of other types of batteriesis just starting. This work does an analysis of the Brazilian law for battery recycling and presents some suggestions and examples of theinitiatives of other countries, in order to manage of this kind of dangerous waste.
