The paper divides resource efficiency of smartphone into three stages; they are resource efficiency of manufacturing, utilization and end-of-life treatment. Output-input evaluation method is used for manufacturing. A real used value of each functionality of smartphone is developed for utilization. An index of resource efficiency for recycle stage is proposed. For each stage, an environmental impact coefficient and TMR are used. Finally the total resource efficiency of a smartphone is derived. This index evaluates resource efficiency both considering mechanical aspect and the real used value by people related to consumption of resources. (C) 2017 The Authors. Published by Elsevier B.V.
