||In recent years, since the environment and climate change dramatically, different countries gradually pay attention to the environmental issues. Two Environmental Directives announced by the European Union (EU) in 2003 were the most well-known and they significantly influenced the industries of electronics and electric engineering. They were “RoHS” and “WEEE”. RoHS, established by EU, sets the standard for 6 hazardous substances (lead, cadmium, mercury, Cr6+, PBB and PBDE) in products. WEEE provides guidelines on increasing the recycling ratio from the wastes.
This paper presents the statements and inquiry concerning the legal regulations and the pertinent progress and development of the two directives proposed by EU in Chapter 2. Then it illustrates and analyzes the design principles of green products in two parts. First, in Chapter 3 it states that the design of the product should conform to the requirements regulated in RoHS and WEEE in the initial stage and accordingly collates the design principles conforming to green products. Second, in Chapter 4 it embarks on the case analysis of the consumptive products in the marketplace. Through the systematic process of analysis, it can be ascertained that whether the parts of product’s construction conforms to the green requirements proposed by EU or not. Finally, in Chapter 5 it proposes the conclusions. This paper expects to promote and facilitate the process of the research and development of green products in the industries relating to electrons and electric machinery.
