Standards and regulations exist to ensure supply chains are not exploitative of the people, environments, and materials with which they interact. This technical note concentrates on two aspects of the process for electronics supply chains: the responsible sourcing of raw materials and end-of-use recycling. It is recommended for use with a companion technical note, "Electronics Supply Chain Overview" (UVA-OM-1716); as well as with the following cases: "Fairphone (A): Can a Start-Up Change an Industry?" (UVA-OM-1712); "Fairphone (B): Is It Really Worth It?" (UVA-OM-1713); and "iFixit: If You Bought It, You Don’t Really Own It" (UVA-OM-1772).
