Our story

Dutch innovations for a resilient industry

As pioneers in metal recovery, we help Europe's stainless steel industry reduce its dependence on virgin metal imports and build a more resilient, circular supply chain. Our technologies recover materials such as nickel, chromium, and molybdenum from production waste, upcycling material that would otherwise be downcycled or discarded into high-grade metals ready to go straight back into steel production.

Since our foundation in 2022, and our spin-off as an independent company in 2026, we've been building the infrastructure European stainless and specialty steel producers need to source critical metals from their own waste — starting with our first commercial plant in Alkmaar.
