The patents were searched to investigate the trend of recycling technologies about plastic waste. Database was collected from WIPS site and the range of the search was limited to patents opened in U.S.A (US), European Union (EU), Japan (JP) and Korea (KR) to september 2009. In this paper, 4,795 patents were selected by investigation abstracts and the trend of the recycling technologies relating to waste plastic were investigated through the analyzing by the years, countries, companies. The patents were occupied 65% by Japan and the most of the patents were about chemical recycling. In the case of Korea, material recycling was major in the patents of waste plastic recycling.

The idea of Sustainable, first mentioned in "Our Future (Bruntdland)" from the United Nations report released in 1987 has been highly affect design disciplines in developed countries in 21st century. It relocated industrial society and structure's attentions to nature and recourse conservation and reuse. Designed and manufactured products eventually disposed and it leads to waste of resources as well as creates environmental issues. Unfortunately, vast majority of designers starts designing without anticipation of this matter and produce more believing this leads to more sales. However shorter life of a product will create bigger increase of resource consumption and waste than, importance of re-usage and recycle will eventually increase. In modern furniture industry metal and plastics are frequently used beside wood that material has been diverse than in past. However, there are lack of plans and regulations of re-usage of those material due to difficulties of separating each different materials and collecting due to it's size. This study would like to look into recycling rate, methods and usage of three major materials (wood, metal, plastic) that is typically used in current furniture industries. Furthermore, see the potential of sustainable furniture by analyzing furniture practices made by each different recycled material from old furniture and what designers should consider to achieve feasibility of sustainable furniture.

The purposes of this study were to deter-mine the dimensions of the housewives' cloth-ing behavior for the environmental protection and the identify the effective variables. The results of this study was intended to provide fundamental material for the establishment of clothing behavior guidelines for the environmental protection. This study was conducted by reference analysis and empirical study. To develop theoreti-cal framework study. To develop theoreti-cal framework of dimensions of environmental protection behavior, references concerned were analyzed. The results of reference analy-sis showed that the dimensions of environmental protection bahavior were resource and energy saving, sold waste reduction, resource reuse or recycle, and green product purchase. The dimensions of housewives' clothing behavior for environmental protection were identified by use of self-administered questionnaires. The results of enpirical study showed that the dimensions of clothing behavior for the environmental protection wre clothing resource reuse or recycle, clothing management resource saving, clothing consumption resource saving, green product purchase, and clothing management resource saving was the highest and that of resource reuse or recycle was the lowest. Environmental consciousness, taking environmental education or not, residing place, clothing seperate-collectiong at residing place were effective variables on clothing behavior for environmental protection.

Although the industrial society gained people with material wealth, they were panic-stricken, felt in lack of everything, not to mention how fast the environment was destroyed. In the midst of this social flow, more and more people who became aware of the problems of the industrial society began to crave happy and beautiful lives through the combination of mental and physical health. This resulted in a new lifestyle called 'well-being'. Lohas, which has become a prominent figure through deep thoughts on social well-being is beyond the persuation of an individual's health and quality of life. Not only does Lohas propose a lifestyle for the mental and physical health of an individual, it also proposes sustainable consumption without hurting the world or the environment. The appearance of the Lohas provided an opportunity not only for people to look in a different aspect on the problems of pollution and ecosystem but to develop and design different products accordingly. Through furniture designs with the idea of lifestyles of health and sustainability applied, this thesis analyses how the main concept of the 3R-Recycle, Reuse, and Reduce is being applied and put to use productively in furniture design.

Silk fabrics are widely used as high quality cloth, interior, quilting and bedding materials because of having excellent touch, drape, resilience and low specific gravity characteristics. But, many waste silk materials are produced during the reeling, spinning, weaving, dyeing and finishing processes. From this fact, the recycle of waste silks is interested in studying for the application of industrial textile materials such as filter, oil absorbent and wound protector. Thus, this research has surveyed the decolorizing and carding characteristics in order to recycle the colored waste silk materials. As the results, the carding condition of waste silk fabrics was optimized with different fiber lengths and curding passage. In addition, the fiber failure mechanism from the wasted silk microdamage caused by carding process was investigated. Also it was found that longitudinal and transverse cracks, abrasion and pilling were formed on the surface of wasted silk fibers.

The slurry stability and removal rate during recycling of slurry in silicon wafer polishing was studied. Average abrasive size of slurry was not changed with recycling time, however, large particles appeared as recycling time increased. Large particles were related foreign substances from pad or abraded silicon flakes during polishing. The removal rate as well as pH of slurry was decreased as recycling time increased. It suggests that the consumption of OH ions during recycling is the main cause of decrease of removal rate. Therefore, it is important to control pH of slurry to obtain optimum removal rate during polishing.

Kobe Steel, LTD. and Midrex Technologies Inc. jointly developed the FASTMET$\circledR$ process as a steel mill waste recycle technology in which the DRI product meets BF feed material or BOF/EAF feed material requirements. FASTMET(R) process turns value-less wastes into valuable DRI and sellable zinc oxide, and gives the solution for the steel mill wastes recycling from both economical and environmental viewpoints. During the development of the process, Laboratory, Pilot Plant and Demonstration Plant tests were carried out from 1990 to 1998. The first FASTMET(R) commercial plant began operation in April, 2000 and the second commercial plant started in April, 2001 Both commercial plants have proceeded successfully preying that FASTMET$\circledR$ is a suitable process for recycling steel mill waste and for producing DRI as an iron source.

Serious problems of the environment protection and resource exhaustion are exhibited. due to the increase of the construction materials and activation of the remodeling, recently. Especially, most of the advanced countries. recycling plan for the waste concrete is vigorously progressing. The purpose of this study is making advances in the recycling of waste concrete material for use as recycled aggregate to make secondary concrete product. Using recycled aggregates form demolished concrete, we manufactured cement bricks to experiment overall performance in Korean Standard and feasible performances. On the recycled cement, in the case of cement : aggregate is 1 : 7 is satisfied with KS F 4004 : dimensions, water absorption, compressive strength of quality of a standard. So we concluded that it has great feasibility to apply these products to construction industry.

Pulp and paper industry is a typical plant industry which usually consume lots of water and energy. Recently, environmental issues have become more important due to climate changes around the world, and reinforcement in the regulatory content in transfer and management of chemical material and that in environmental regulations for waste water and air. Paper industry is a source material recycle industry which recycle or reuse waste paper, recyclable wood, planned plantation or lumber from thinning and waste wood. Hence it can be said that paper industry is the representative industry for earth environment and of 21th century.
