Lead Acid Batteries

Lead-acid batteries, the oldest rechargeable battery technology, are utilized in a diverse range of applications. They serve as reliable power storage solutions in small-scale setups like UPS systems and act as vital sources for starting, lighting, and ignition in vehicles, while also finding application in large, grid-scale power systems.

One notable advantage of lead-acid batteries is their extensive recyclability. Lead-acid battery recycling is a crucial practice that addresses both environmental and economic concerns. These batteries contain hazardous materials like lead and sulfuric acid, which can have severe detrimental effects on the environment if not properly managed. When lead-acid batteries are disposed of improperly, they can leak toxic substances into the soil and water, leading to contamination and posing risks to human health and wildlife. Recycling these batteries not only prevents the release of harmful chemicals but also reduces the demand for new raw materials, conserving natural resources and minimizing the environmental impact associated with mining and production.

At Blancomet, we have developed a unique recycling process that ensures the complete recovery of all battery components. This includes the retrieval of valuable materials such as lead, polypropylene, ABS, and sulphuric acid. These components are then sent to refiners, where they undergo further recycling to manufacture new products. By implementing such a recycling process, we contribute to the establishment of a circular economy, where end-of-life assets can be repurposed and utilized once again. Through our efforts, we promote sustainability and reduce waste in the battery industry, fostering a greener and more environmentally conscious future.

The economic benefits of recycling lead-acid batteries are substantial as well. The process allows for the recovery of valuable materials like lead, which is a primary component of the battery’s construction. This recovered lead can be used to produce new batteries, reducing the need for lead mining and smelting. Recycling also helps create job opportunities in the recycling industry and contributes to the overall circular economy by repurposing materials and reducing waste.

Knowing when a lead-acid battery can be reused or recycled depends on its condition:

  • Reusability: If the battery is still holding a charge and functioning effectively, it may be suitable for reuse. Some auto parts stores or battery retailers offer programs where you can exchange your old battery for a new one at a discounted price.
  • Recycling: If the battery no longer holds a charge, shows signs of physical damage, or is nearing the end of its typical lifespan (usually around 3-5 years), it’s recommended to recycle it. Authorized recycling centers have the expertise to safely extract valuable materials for repurposing.

To safely unplug a lead-acid battery from a car and deliver it to a recycling company, follow these steps:

  • Safety Precautions: Put on appropriate protective gear, including gloves and safety goggles, to safeguard against any potential contact with battery acid.
  • Identify the Battery: Locate the battery in the vehicle’s engine compartment or in the back. It’s typically a rectangular or square-shaped unit with terminals marked as positive (+) and negative (-).
  • Disconnect the Negative Terminal: Begin by loosening the nut on the negative terminal (“-“) using a wrench. Once the nut is loosened, carefully lift the negative terminal off the battery post and place it away from the battery.
  • Disconnect the Positive Terminal: Repeat the same process for the positive terminal (“+”). Loosen the nut and remove the positive terminal from the battery post.
  • Inspect and Clean: Examine the battery and terminals for any signs of damage or corrosion. If needed, clean the terminals and posts using a mixture of baking soda and water to neutralize any acid residue and corrosion.
  • Secure the Terminals: Ensure both terminals are securely positioned away from the battery posts to avoid accidental contact.
  • Transport to Recycling Center: Place the disconnected battery in a secure and upright position to prevent spillage during transportation. Transport the battery to an authorized recycling center or a designated drop-off location for hazardous waste.

By following these guidelines, you can contribute to responsible lead-acid battery recycling, promote sustainability, and help reduce the negative impact of battery waste on our environment.
