Recovery of used products is receiving much attention recently due to growing environmental concern. Ecient
implementation requires appropriate logistics structures to be set up for the arising goods ¯ow from users to
producers. We investigate the design of such logistics networks. As a basis for our analysis we review recent case
studies on logistics network design for product recovery in dierent industries. We identify general characteristics of
product recovery networks and compare them with traditional logistics structures. Moreover, we derive a
classi®cation scheme for dierent types of recovery networks.
