The treatment of technical consumer products after using is important for the conservation of our environment. In this paper the demanufacturing technology that is required to maximize the recycling rate of end-of-life products is introduced, The definitions including types of the recycling are described. The factors that have to regard in the design stage of products in order to maximize the recycling rate of the products are introduced. The objective assessment methods for the design for environment are described. Finally disassembly process and future prospect of the automations are discussed.

Reusing is one of the most environmentally friendly recycling methods. For the economical remanufacturing of used cellular phone, the cellular phones should be design for easy disassembly. In this paper, we analyzed the components and connecting elements of cellular phones and developed a guideline for the design of the cellular phones. A software for the disassembly assessment was also developed. Redesigned cellular phone by the developed guideline and its original phone was analyzed by the disassembly assessment software. Disassembly time could be reduced about 40% and reusing rate could be improved about 37%.
