Reverse Logistics is a rather general term. In its broadest sense, reverse logistics stands for all operations related to the reuse of products and materials. The management of these operations can be referred to as Product Recovery Management (PRM). PRM is concerned with the care of products and materials after they have been used. Some of these activities are, to some extent, similar to those occurring in the case of internal returns of defective items due to unreliable production processes. Reverse logistics refers however to all logistics activities the collection, disassembly and processing of used products, product parts and/or materials in order to ensure a sustainable (environmentally-friendly) recovery.
