More Detail about Recycling of Lead Acid Battery
Because lead acid battery contains lead, lead compounds and sulfuric acid, they are hazardous waste. And they are still hazardous wastes even when drained of acid because they still contain lead. Lead compounds can be absorbed through ingestion and inhalation. Moreover, lead is an acutely and chronically toxic compound, and is also highly toxic to fish, other animals and plants. Acid is corrosive which may hurt you and damage your skin if it touches you.
Therefore, we need to recycle the lead acid battery because toxic components pose a potential risk to the environment and human health. So we can get many benefits of lead acid battery recycling.
Lead acid batteries have many components that are re-usable but how exactly are they recycled? In this blog we will go into more detail about the recycling of lead acid batteries and there components. 3 components of lead acid batteries that are recycled include Plastic, Lead and electrolyte these components are recycled in many different ways but inevitably end up becoming lead acid batteries again. Below we have a diagram that shows the method.
Plastic – The pieces are washed and dried and sent to a plastic recycle company they are then melted together, this then makes the plastic into a liquid form, it is then turned into small plastic pellets which are then sold back to the battery manufacturer. They are then used for the outer casing of the lead acid batteries.
Sulfuric Acid – The acid can be used in 2 separate ways. The first is to turn the acid into a sodium sulfate, which is a white odorless powder which is used in laundry detergent. The other use of the acid is to neutralize it; this turns the acid into water; then is released back in to the sewer system.
Lead – All the lead parts from the battery are melted together in smelting furnaces, and then those are treated and remove any impurities. The lead is then put in a mold, cooled and sent to the battery manufacturers, they can then re-use the plates in new batteries.
Anyway, the lead acid battery is all recyclable to a lesser or greater extent. This only means, however, that a battery can be recycled after it is spent. The battery itself does nothing to close the recycling loop if it is not recycled, but we, our governments or our industries can ensure that they enter the loop by creating an infrastructure that will promote and facilitate recycling.
