There is absolutely no doubt about the fact that the batteries are the most important component of cars and are essential to keep them running. But after a point, batteries need to be changed and the old ones need to be taken out. In such a case, what does one do with the old ones? Just throw them away? Well, rather than throwing car batteries away, it is always better to get the recycled.
It is one way through which you can minimize the damage done to the environment and play your part in maintaining the environment. The following is some more information about recycling of car batteries.
What are Car Batteries Composed of?
The first question that you may have on your mind is what are car batteries made of? Well, they are composed of heavy metals like lead, mercury, cadmium, nickel and sulfuric acid. All these metals can harm the environment and if they are not disposed of properly, they can pollute the soil and also endanger the wildlife. This happens when the poisonous chemicals and metals get mixed together with the soil when the battery gets deteriorated. This is why a lot of stress and focus is on recycling of car batteries these days.
How to Recycle Car Batteries?
- The first step to recycle a car battery is to take it to a roundup. These roundups are held each year if a local office and are the best places to get your batteries recycled.
- You must know that all the components of the old battery will be reused to create new batteries which will be given to you or can be sold by you to get money.
- Another option for getting your old car batteries recycled is to take them to an automotive shop. These shops too help you to get a new battery while they themselves will keep the old.
- The process of recycling starts when combustible materials such as plastic and the insulation are first removed. A thermal oxidizer fired by gas is employed in this process and the gases are sent to a plant which removes the pollutants and neutralizes it. This is the process which thus results in clean cells. Also, this process helps to remove any valuable metals that may be present in the batteries.
- Now the cells obtained are cut down into small pieces and are then heated. They are heated till the metal turns to liquid. The non metallic substances left are burnt and they leave a black slag behind.
- At high temperatures, cadmium vaporized due to its light weight and this process looks as if it is being pan boiled. In some of the cases, metals may not get separated during recycling but are heated directly. After this each metal is segregated to result in alloys.
Recycling may be a small but is a very important step for the environment and everyone must follow it.
