Primobius becomes wholly owned subsidiary of SMS group
by David Fleschen

SMS group has acquired the remaining 50 percent stake in Primobius GmbH from Australian partner Neometals, making the battery recycling specialist a wholly owned subsidiary. The transaction, completed on 12 September 2025, marks a strategic milestone in SMS group’s long-term commitment to industrial-scale, sustainable lithium-ion battery recycling.
Primobius will remain a legally independent entity within SMS group, managing its operations autonomously while gaining expanded access to the group’s global engineering resources and commercial network.
Founded as a joint venture between SMS group and Neometals, Primobius offers fully integrated solutions for lithium-ion battery recycling — from discharging and dismantling to shredding, material separation, and hydrometallurgical refining. Its multi-stage process enables the recovery of critical battery materials at high purity levels while minimising environmental impact.
“With the full acquisition of Primobius, we are strengthening our group-wide capabilities in sustainable battery recycling and sending a clear message about our long-term commitment to this growth market,” said Thomas Hansmann, CTO of SMS group. “We are reinforcing Primobius’ market position and supporting the company as it deploys its industrial-scale recycling plants worldwide.”
While Neometals has exited the joint venture, it will continue to support the technology through a long-term service agreement, ensuring continuity in joint development and innovation.
Michel Siemon, CEO of Primobius, commented: “Together with our shareholders, we have developed a battery recycling solution that already sets international benchmarks. Our close collaboration with Neometals has been instrumental in achieving this and will continue under our long-term service agreement. We are proud to provide our customers with battery recycling plants that recover critical raw materials in high purity, maintain valuable resources in the loop, and make a measurable contribution to the sustainability of the industry.”
