Mining of precious metals has increased dramatically in the past few decades to meet demand resulting, often, in severe environmental damage and human health consequences as well as depletion of valuable mineral resources. Metals differ from other resources in that they remain with us forever in some form. Recycling metals following their use provides an important means to reduce the environmental burden resulting from mining primary ore, ensures the availability of a valuable secondary source of the metal, and conserves an irreplaceable resource that otherwise would be discarded. Challenges and benefits associated with recycling precious metals are presented here. Emphasis is placed on the need for greater use of green chemistry recycling processes for effective recovery of these precious resources to prevent their extensive loss to the commons. Molecular Recognition Technology (MRT) is presented as an effective green chemistry process in commercial metal recycling together with selected examples of its use.
