The U.S. Navy and GE Aviation are collaborating on an environmentally beneficial program to recover rhenium-bearing aircraft engine components from out-of-service F404 and F414 engines and then incorporate this precious metal back into the manufacture of new engine parts. This effort is aimed at reducing raw-material requirements, lowering dependency on foreign sources of rhenium, and providing financial "credits" the Navy can apply to future engines and hardware. Rhenium is a prime component in turbine blades and stators. GE has an arrangement with a Navy-approved vendor who receives and subsequently processes these parts for material reuse. Other metals are recycled from these parts as well.
