To construct the Sustainable Society, the importance of consideration to 3R (Reduce , Reuse , Recycle) in the design phase increases in various industrial products. Concerning Reuse and Recycle, the improvement of the disassembly property is important. Then we develop the quantity disassembly property assessment method Disassembly Property Index (DPI), one of the DfE (Design for Environment) supporting tool. Additionally, the quantitative environmental load assessment is also necessary to achieve the sustainable society. Though various LCA (Life Cycle Assessment) method is developed for such a demand, it is pointed out that there are a lot of problems in existing LCA. To solve such problems, Eco-Efficiency Potential Assessment (E2-PA) is developed. E2-PA is based on the concept of "Eco-Efficiency" and the "Potential Assessment". In this paper, we pay attention to Domestic Appliances (SDA) including digital cameras. Recently, digital cameras are produced and wasted in large quantities, therefore, it is hoped to be recycled. Then, we examine the consideration of 3R and environmental load assessment about them.
