Lead-acid battery recycling is a crucial process that helps conserve natural resources, reduce environmental impact, and support a circular economy. Lead-acid batteries are widely used in automotive and industrial applications due to their reliability and high energy output. However, improper disposal can lead to environmental hazards due to the toxic nature of lead and sulfuric acid. Let’s understand how this recycling process works.
Used lead-acid batteries are collected from dealers, automotive workshops, and recycling centers. Industrial Batteries are transported to authorized recycling facilities following proper safety and environmental regulations.
Collected batteries are mechanically broken down in a hammer mill or shredder. Components like lead, plastic, and electrolyte are separated using gravity and filtration techniques.
Separated lead is melted in a furnace at high temperatures. Impurities are removed through a refining process. The purified lead is cast into ingots for reuse in manufacturing new batteries.
Battery cases (typically made of polypropylene) are cleaned and shredded. The plastic is melted and remolded into new battery cases or other plastic products.
Sulfuric acid from the electrolyte is neutralized with industrial-grade chemicals. Neutralized acid is processed into sodium sulfate, which is used in detergents, glass, and textiles.
Emissions and waste products from the recycling process are treated to meet environmental regulations. Air filtration systems capture and neutralize harmful gases and particulates. Water used in processing is treated and recycled to minimize environmental impact. All these units comply with CPCB and battery waste management rules.
Refined lead and recycled plastic are reused to manufacture new batteries. This closed-loop process reduces the need for raw materials and minimizes environmental impact.
Sustainable practices ensure that the recycling process remains eco-friendly and efficient.
