DREV develops the Vault family of contamination-control products (Vault Mobile, Vault Stationary and Vault Autonomous) for battery gigafactories, recycling plants and refineries. The systems use a patent-pending dry brush technology and canister that avoid water and harsh chemicals, capturing airborne and settled metal particles at source. Captured material can be reprocessed to recover critical metals such as nickel, cobalt, lithium and copper. The company plans processing facilities near major gigafactory sites in Sweden, Poland and Hungary.
