On World Engineering Day for Sustainable Development, hereâs a concrete example of how engineering drives a more circular and responsible future.
Caroline, an engineer working on traction battery circularity, explains how a single battery can contribute value far beyond its first use on a truck:
1ïžâŁ First life on the vehicle
After thousands of kilometres, a battery is inspected to assess its health and potential for repair.
If components are failing but repairable, the battery can be refurbished and returned to service.
2ïžâŁ Second life in stationary applications
When a battery no longer meets the performance levels required for heavy-duty vehicles, it can still provide reliable energy.
It is then repurposed for energy storage, for example to support buildings, microgrids or charging infrastructure.
3ïžâŁ Third life: recycling and material recovery
At the end of its usable life, the battery enters a recycling loop.
Critical materials can be recovered and reintegrated into the production of new batteries, reducing the need for virgin resources.
đ€ Why this matters?
Extending battery life helps lower environmental impact across the value chain.
Repurposing and recycling reduce the demand for critical raw materials.
Circularity supports a more affordable and sustainable electric mobility ecosystem.
Caroline sums it up well:
âThe earlier we design for circularity, the easier it becomes to repair, repurpose and recycle batteries throughout their entire lifecycle.â
