Workplace Examples of Df. D: • “BMW's 1991 Z 1 Roadster, whose plastic side panels come apart like the halves of a walnut shell, is an example of a car designed for disassembly. One of the lessons learned, is that glue or solder in bumpers should be replaced with fasteners so that the bumpers can come apart more easily and the materials can be recycled…Now BMW uses variations of polyurethane, foam, and rubber so the panel can be recycled. The portion of a car recycled is 80% by weight and BMW is aiming for www. assignmentpoint. com 95%. ”

Workplace Examples of Df. D: HP products are designed to be recycled. Recycling design features include: • Modular design to allow components to be removed, upgraded or replaced • Eliminating glues and adhesives, for example, by using snap-in features • Marking plastic parts weighing more than 25 g according to ISO 11469 international standards, to speed up materials identification during recycling www. assignmentpoint. com

Workplace Examples of Df. D: HP Continued: • Reducing the number and types of materials used • Usingle plastic polymers • Using molded-in colors and finishes instead of paint, coatings or plating • Relying on modular designs for ease of disassembly of dissimilar recyclable materials www. assignmentpoint. com

Workplace Examples of Df. D: • GE Plastics is involved in numerous consumer recycling efforts, from making tea kettles that are easy to disassemble and recycle to turning old plastic computer housings into roof tiles for restaurants. It's trying to put that kind of ingenuity to work for automakers not only in Df. D, but also in design for serviceability (Df. S). Greg Jones, GE Plastic's manager of design development, currently sees more OEM interest in Df. S than Df. D, but he sees them as being closely related. www. assignmentpoint. com

Is it easy to disassemble your product? • When using the checklist, you may want to apply a weighting scale; doing so will help you see your most important parts of the disassembly process and interpret your weak and strong areas. www. assignmentpoint. com

Summary With the growing world demand for manufactured goods, and the decreasing availability of landfill space, recycling is becoming more of a necessity than a good idea. By making it possible to re-use product parts, companies can decrease their production costs, decrease refuse and landfill materials, and increase their quality management. A company that can recycle and re-use their own parts is not only ahead of the game of the future, which will eventually require compliance with Df. D, Df. S, and other green design initiatives, but that company is also at an advantage compared to others in their industry who have not considered such changes. www. assignmentpoint. com
