Here's a riddle: What's a foot long, is sitting in your car, and has about 20 pounds of poison in it? Want a hint? You probably never think of it unless your car won't start.
Yes, it's your car battery, which contains 18 pounds of toxic lead, and a gallon of sulfuric acid - two hazardous wastes you don't want to dump into the environment.
Fortunately, you can take a car battery to a gas station or auto parts store, and they'll recycle it for you.
Americans recycle about 80 percent or our car batteries. But the other 20 percent - containing about 330 million pounds of lead - wind up in landfills.
How are batteries recycled? Companies called "battery breakers" crack each one open and drain out the sulfuric acid (which is either reprocessed or sent to a hazardous waste facility). Then the batteries go to a scrap yard. The lead is removed and shipped to a mill, where it's melted down into ingots. It's sold to manufacturers......and might very well end up in you new car battery. The polypropylene case is also recycled.
Why recycle? It's estimated that three out of every four Americans who change their own car batteries throw them away instead of recycling. In landfills, battery cases eventually crack, allowing the lead and acid to pollute groundwater.
Lead is poisonous. It can cause liver, kidney and brain damage. Batteries contribute 2/3 of all lead in municipal waste. Incinerating batteries spews lead into the air.
