Most car batteries are made of heavy metals, such as nickel, cadmium, lead, mercury and sulfuric acid, and these metals are a cause for environmental concern. If not disposed of in the proper sequence, these toxic chemicals and metals will mingle with the soil as the battery deteriorates, thus endangering wildlife and polluting the soil. There are several components in car batteries that mix with water and enter the food chain of human beings, because of which human life is in danger too. For these reasons, recycling has gained immense importance.
How to recycle a car battery?
When you think of recycling car batteries, the first question that comes to mind is how to do it? To begin, you must not only throw the battery in the trash with your household waste. A car battery consists of at least 3 and 21 pounds of plastic and lead, respectively, and a gallon of sulfuric acid. Imagine the number of toxins released into the atmosphere if a car battery is left in the open.
The first option you have for recycling the car’s battery is to take it to a roundup. They are organized every year to mark Earth Day. You can get the details of a roundup at a local AAA / CAA office.
While recycling a used battery, all components, whether metals or acids are reused in new batteries. For example, lead is normally used in new batteries again and again. Plastic found in batteries are also recycled to be used in other batteries, or are, at times, also made in other products. Sulfuric acid is neutralized and purified before its release as pure water, or it is reused in other new batteries. In addition, sodium sulfate can also be made from sulfuric acid to be used as fertilizer or dyes.
Another option for recycling used car batteries is to take it to an auto repair shop, which helps you get a new battery while they keep the old one. Today, there are laws in some states that require you to recycle new lead-acid batteries once they are old, and when you buy a new battery you need to pay a down payment.
The recycling process begins when combustible materials such as plastic and insulation are removed. A gas-heated thermal oxidation device is used for this process and the gases are sent to the plant scrubber which is neutralized and eliminated pollutants. Through this process, the cells are cleaned and the valuable metal can be removed.
These cells are cut into small pieces, after which they are heated until the metal turns into a liquid. On the other hand, substances that are non-metallic are burned thus leaving a black slag. As by the weight of the alloys, they install and then are skimmed. At a very high temperature, cadmium vaporizes because of its lightweight. The process seems like if you are boiling pan. At times, while recycling, the metals are not separated, but are heated directly and then each metal is separated to produce alloys.
So, recycling a car battery is a small but important step that you can take to save the environment from harmful chemicals and pollutants. You must remember that all toxic metals, thrown back into the open, come back to us, either by the food we eat, or the water we drink and can harm us in the long run.
