Today the tastes of consumers change rapidly and the kinds of the products become diverse. Therefore the product life cycle becomes shorter and shorter. Moreover the save of resources and the recycling for the environmental preservation are the essential theme. On this the necessary information for the product development increases enormously. For the right use of the information the design process should be supported by the proper design tool. For this the 'design catalogue system for recycling' is suggested here. This system consists of four parts, that is, 'the existing automobile system database', 'working principle database', 'assessment system of the ease of disassembly' and 'one's own product development database' By the use of this system the product development period could be reduced about 30% drastically.

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.

Product design should reflect environment and experience of use in consideration of product's role as well as roles in life. In doing so, it is expected to realize interaction between product's role and users. Therefore, design of a recycling bin should also consider not only colors, shape, or materials but also process and experience of use. This study was conducted targeting public recycling bins in Beijing. As for the study method, first concept of a recycling bin was defined while specifying significance of recycling in Beijing City. Also, advanced research on recycling related policies that are currently being promoted was carried out. Second, current status of recycling in Beijing and problems of recycling bins were analyzed through on-campus survey. Lastly, users' psychological demand on a recycling bin was assessed and analyzed to suggest developmental direction of recycling bin design in the future.

The purpose of this study is to investigate the main characteristics of the environment-friendly design expressed in Koran fashion. Environment-friendly design can be categorized into choice of material, extension of products life cycle, and recycling design. In this study, Korean fashion designers can be found having the conciousness of environment for fashion design since 1990. First, in choice of material, the designers used Natural fibers which are cotton, linen, wool, and etc, and used natural dyes. Some of the designers have moved from using real fur to using fake fur for animal welfare. But fake furs produced from synthetic or regenerated fibers have the environmental problems during textile production processes. Some of the designers used fake leather made from the skins of an edible fish which are otherwise going to waste. Secondly, Design for extension of products life cycle can economize the resources and energy. Design for extension of products life cycle are classified into reversible clothing, many function clothing, modular style, patina clothing, simple style, and layered look. Finally, recycling design are classified into recycling of daily necessaries and expression techniques of recycling design which are designer's works used patchwork, mash techniques, and handmade of knits or buttonhole stitch.

This study deals with the technological trends in the automobile recycling technologies. It first discusses the importance and current situation of automobile recycling. And then it discusses the technological trends in automobile recycling industry classifying the technologies into three groups: disassemblying, recycling, and design. It deals with recycling of major parts of automobiles and the design of automobile for recyclability. This study also contains a patent analysis of the technologies. Different patterns in the trend of patents among various conn-tries are discussed with the context of legal and industrial situation of each country And finally it discusses the forecasting for the future technological and legislative trends.

In this paper, shortening of product life cycle and wide disposal of consumer product have given rise to many environmental problems, it needs to propose module design principle for saving of disassembly cost and reusing of used part and subassembly. To analyze characteristics of module for recycling, materials and function of part and subassembly must be classified. In disassembly process, a unit operation can be grasped for disassembly function, worker, tool and sorting process. As a result of applying module design principle, simpler structure and reduced structural interference can be realized for product structure. For disassembly, simpler disassembly and quicker disassembly can be obtained for recycling.

Recently, metal-composite hybrid structures became a very attractive material system for various applications such as automobile and air vehicles due to their design flexibility as well as superior mechanical properties. On the other hand, recycling is a hot issue to reduce material wastes and environmental pollution, so that many countries made recycling regulations. But the recycling of metal-composite hybrid structures is not fully considered since the development and application are very early stage. We developed and optimized the recycling process for metal-composite hybrid structures based on the easy adaptation of the local recycling companies.

Increasing concerns of environment need to make change furniture field to more environmentally friendly approach, such as reuse of by-products from wooden products. As it is, the methods of recycling wood for industrial purposes have the advantage of productivity and adaptability. However, the industrial way is required a certain production facility of processing wooden by-products and has possible hygienic problems due to contaminated sources. Many designers have developed their own methods for reuse of wood in unique and artistic ways. Even so, because of confined sources, it could be not enough supply. Therefore, I developed the design methodology utilizing wooden by-products from S Design Company to relieve former ways' problems. The design suggestion took materials from a safe and abundant source. The wooden leftover pieces were connected together with epoxy clay, so previous process traces of furniture are remained as a decorative factor. Moreover, the synthesized material was able to be processed by ordinary woodworking facilities without additional installations. In doing so, console table focused on a commercial purpose and dining table for an artistic objective were successfully fabricated as final suggestions. In consideration of the proposal using wooden furniture leftovers, diverse recycling designs should be investigated for future reference.

In this study, it was developed eco-friendly mix design of mine sprayed concrete, which satisfies both the stability and economics by mixing the industrial in cement, for development of the mine sprayed concrete and recycling of industrial. From this research, it is found that mixing of mineral admixture is effective on strength enhancement. Also, it is considered that designed mixing ratio of sprayed concrete using industrial byproducts should be applied to the field through field test.
