Batteries can cause fires when they spark against metal objects (including other batteries) or short circuit and overheat. Battery fires in collection trucks and at waste and recycling facilities are a workplace hazard and a risk to the community. Any type of battery can cause a fire.
Batteries also contain toxic materials such as cadmium, lead, zinc manganese, nickel, silver, mercury and lithium. In landfill, these chemicals contaminate the soil and groundwater, harming the environment, wildlife and the community.
Fortunately, if disposed of correctly, most of the materials in batteries can be recovered and recycled.
