108 Screws
Adventures in EcoDesign of Electronic Products 9.4 Will China show the way? In China legislation of the type of WEEE, RoHS and EuP is underway. For WEEE and RoHS drafts have been published. A draft for EuP has not yet been made public. A basis for this legislation has been laid by studies in China itself. Moreover, Chinese delegations have been visiting Japan, Europe and the USA to assess the developments in those regions of the world. The Chinese strategy to develop environmental legislation for electronic products will consist of three elements: Take on board elements of legislation elsewhere in the world that are appropriate (and do not take on board what is inappropriate). Introduce specific Chinese elements. Look at cost consequences/economic impact from the very beginning. The debate in China about the draft legislations is in full swing. What the outcome will be is at the time of writing still unsure. Nevertheless there are four elements in the Chinese debate which are useful to consider when reviewing WEEE. These elements will also be helpful to come to a better implementation strategy for ROHS in Europe and will avoid WEEE type disasters on implementation of EuP. These are: 1. Make laws to formulate the environmental intent/goals, but make standards to specify the implementation. Advantage: the law can stay in place, standards can be modified according to growing experience, technological developments, and changing prices respectively cost. 2. Formulate organizing principles and formats for procedures, before implementation. Advantage: more uniformity among regions/provinces. 3. Use catalogs of products to be considered instead of product categories. Advantage: priority setting, no scope discussion. 4. For overall improvement purposes put EcoDesign, technology development and system organization on equal footing with functionality optimalization. Advantage: the life cycle principle is in the lead ?all technicalities are equally subordinate. ???Tidbits, 14 Design for disassembly was a popular subject in the Nineties. In order to do it properly a disassembly analysis is necessary. Methods to do this are available (see chapter 7.3), but the biggest problem has not been solved yet. After identification of opportunities for simplifying the product structure, acceptance of the proposed changes by the product creation team is still necessary. The answer is simple: involve the team, make a sport out of it. A good trick is to ask team members at the kick off of a disassembly session how many screws they think are in the present product. In the case of a monitor, disassembly session guesstimates ranged between 30 and 50. After disassembly it turned out that there were 108! The same question was asked to the general manager who came to review the results of the session. So far he had been suspicious about environmental activities, but nevertheless had approved the session to take place.
