Batteries
Because they contain various hazardous materials, including heavy metals and acids, batteries can cause serious environmental harm if not discarded properly. Battery disposal laws can vary greatly across regions and municipalities, so check your local government website for regulations and options for proper disposal which can include recycling facilities, hazardous waste facilities, or designated drop-off sites in your community. Be sure to properly store and care for used batteries before you dispose of them to minimize the risk of fire and dangerous chemical leaks.
