Promotrame has mastered the treatment and recovery of industrial waste and recovered materials containing metals.

First intended for the treatment of P.T.T. (lead, armored cables), it has gradually diversified into iron metals (electric motors, armatures, telephone exchanges, electrical cabinets, etc.), but also in electronic equipment (computers, peripherals, components, cards, etc.) ), and excels in toll processing. It maintains privileged links with major metal groups, refiners, and a transnational and diversified clientele.
