Lead batteries: the circular economy in action

The recycling of lead batteries is a model of successful circular economy, thanks to a recycling industry that was established in the 1990s and is well-structured and efficient. With a recycling rate of 92% for components, including 99% for lead, this industry demonstrates that it is possible to transform waste into a resource while protecting the environment.

A mature and efficient sector

The recycling process begins with rigorous collection from garages, sorting centres, businesses and retail outlets. Used batteries are then transported to approved treatment centres specialising in the decontamination and recovery of various materials.

Key stages of treatment

• Acid neutralisation: electrolytes are treated to eliminate any environmental risk.

• Shredding plastic packaging: polypropylene is separated and reused in new production processes.

• Lead extraction: this metal is isolated, purified and remelted for use in the manufacture of new batteries.

The circular economy loop is then closed.

Lead: a strategic resource that can be recycled indefinitely

Beyond the environmental issue, this industry also meets major industrial needs. Lead is a critical material, essential to many sectors. Its key advantage is that it can be recycled indefinitely without any deterioration in its properties.

Between 2015 and 2017, the collection and recycling rate for lead batteries in Europe already reached 97.3%. This level, which is still rising today, demonstrates the effectiveness of a virtuous model that reduces dependence on mines and limits the economic, social and environmental impacts associated with extraction.

A collective success

This performance can be attributed to ongoing cooperation between producers, distributors and recyclers. Each player has a role to play in the chain of responsibility, ensuring optimal flow management, efficient collection and maximum recovery of raw materials.

Towards a new form of governance: Extended Producer Responsibility (EPR)

The introduction of Extended Producer Responsibility (EPR) for lead batteries, scheduled for summer 2025, represents an important step forward. However, this reform must ensure that the balance is maintained in a sector that is already exemplary, with recycling rates well above European regulatory requirements. Any changes to the framework must be carefully calibrated so as not to undermine an already successful model.

Conclusion

Lead-acid battery recycling is one of Europe's great industrial successes in terms of the circular economy. With record recovery rates and a significant reduction in environmental impact, this sector is leading the way for others. It demonstrates that a more sustainable, responsible economy that is less dependent on primary resources is not only possible, but already operational.
