Jälle Technologies

At Jälle Technologies, we believe the future of energy storage depends on rethinking how we treat battery waste. Every used battery holds critical materials that are too valuable—and too environmentally costly—to discard.

​

We started with a simple but ambitious idea: What if waste wasn’t waste at all? What if it could become a reliable, sustainable source of essential materials, supporting Europe’s independence from imported resources and reducing the environmental burden of mining?

​

Our journey began with a team of researchers and innovators united by more than technical expertise. We share a can-do attitude and a relentless drive to turn ideas into reality—into tangible results that create meaningful impact. We want to leave our mark, to make our dent in the universe by tackling one of the most pressing sustainability challenges of our time.

​

We know innovation doesn't happen by playing it safe. We're not afraid to make mistakes, because that's exactly where the breakthroughs lie. We believe in moving fast, experimenting boldly, and learning quickly—understanding that real progress often means breaking things and rebuilding them better.

​

Our mission is clear: to enable a truly circular battery economy. By developing efficient, sustainable recycling processes, we’re helping keep critical materials in continuous use, reducing environmental impact, and laying the foundation for a low-carbon, resource-secure future.

​

But for us, this isn’t just about technology. It’s about delivering real, lasting value—for industry, for the environment, and for society. We’re committed to working openly with partners, investors, and future team members who share our vision of a cleaner, more resilient world—built on action, collaboration, and the courage to innovate where it matters most.​

Why “Jälle”?

Jälle is an Estonian word that means “again” or “renewed.”

​

We chose this name because it perfectly captures what we stand for: giving valuable materials another life instead of letting them go to waste. Our mission is to create true circularity in the battery industry—so that critical resources can be used again and again, reducing environmental impact and building a more sustainable future.

​

At Jälle Technologies, we believe that nothing valuable should be lost. Everything deserves another chance. That’s why we’re here.
