About Jälle Technologies

Jälle Technologies is a cleantech startup turning battery recyclers’ biggest headache — graphite-rich waste — into their greatest opportunity. Our proprietary process upcycles this residue into a high-performance 2D material with applications across energy storage, coatings, composites, electronics, and more. By transforming a costly waste stream into a valuable resource, we close a critical gap in the battery recycling chain. Instead of relying on mined graphite and harsh chemical processes, our method leverages the unique properties of recycled graphite, making production more efficient, scalable, and sustainable. We work as the missing link between recyclers and manufacturers: recyclers gain a profitable outlet for graphite waste, and industries gain access to advanced materials at lower environmental cost. Founded by a team of scientists and cleantech entrepreneurs, Jälle is building Europe’s first integrated pathway from battery recycling residue to graphene-based materials — positioning Estonia at the forefront of circular, high-value material innovation.
