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.

The cosmetics industry faces a significant challenge in addressing the decreased recycling rate of cosmetic containers due to the composite materials used to meet consumers' aesthetic satisfaction. To address thees issues, eco-friendly packaging solutions such as refill packaging and single-material use have been developed. However, the market for eco-friendly cosmetics packaging requires a product that meets consumers' demands for aesthetics, sensitivity, and eco-friendliness while also performing as well as existing products. This study presents a solution to the challenge of the decreased recycling rate of cosmetic containers by developing a new cosmetic packaging product for cream formulations. The product features an easily separable and dischargeable internal refill container, while maintaining the design aesthetics of the external container. Through various tests, the product was shown to be of equivalent quality and performance to existing cream cosmetic packaging, with no leakage or defects observed. Furthermore, the use of a single-material polypropylene refill container is expected to contribute to the improvement of the plastic recycling rate.

Electric vehicles (EVs) are spreading rapidly and many counties are promoting hybrid and fully EVs through legislation. Therefore, an increasing amount of lithium ion batteries will reach the end of their usable life and will require effective and sustainable end-of-life management plan which include landfill disposal or incineration. The current research focuses on more sustainable methods such as remanufacturing, reuse and recycling in order to prepare for future battery compositions and provide insights to the need recycling methods to be developed to handle large amounts of batteries sustainably in the near future. The two most prominent material recovery techniques are hydrometallurgy and pyrometallurgy which are explored and assessed on their relative effectiveness, sustainability, and feasibility. Hydrometallurgy is a superior recycling method due to high material recovery and purity, very low emissions, high prevalence of chemical reuse and implementation of environmentally sustainable compounds. Expanding recycling technologies globally should take the research and technologies pioneered by Umicore to establish a sustainable recycling program for end-of-life EVs batteries. Emerging battery technology of Telsa show the most effective designs for high performance batteries includes the use of silicon which is expected to increase capacity of batteries in the future.

Focusing on 'reuse' with a view to the importance of unused cloths, this paper investigates the aspects of consumers' recycling attitudes regarding the cause and treatment of unused clothes. This research examines the responsibilities for recycling from the standpoint of consumers, and shows their requirements and advice to consumers themselves, clothing companies as the subject of production and the government and society. Considering the pattern of clothing life, this research deals with housewives who live I Seoul, Sung-nam and Choong-ju. After several pretests, the content and format of this questionnaire is revised and added. This investigation is carred by individual interviews and reponders' filling-out, from 24 November 1997 to 5 January 1998. Among the total 1,200 questionnaires, 1,150 sheets are taken back, but only 1,132 are available to analysis. The results are as follows: Most of all, among the causes of unused clothes, the problem of clothes itself is stemmed from the more responsibility of clothing companies rather than consumers'. From production to sale the companies, considering environment and recycling, should choose proper cloth material and adequate design. And then they require the consumers' attention to laundry and conservation. More important, consumers' attitudes should be changed because consumers themselves, in fact, recognize their responsibilities for recycling of clothing, from the questionnaire. After all, the recycling of clothing should lead to reduction of unused clothes as a fundamental solution. When it comes to unused clothes, its elimination pays more money and needs specialization. Moreover, citizens should participate in the problem independently and more information on the policies of recycling should be well-informed.

Around the 1980s, with government's promotion and dissemination policies for FRP (Fiberglass Reinforced Plastics) of the government as a main material of fishing boats, approximately 97% of the entire fishing boats in Korea have utilized FRP until now. Nevertheless, diverse social and environmental issues have emerged due to the susceptibility to fire and the generation of substances detrimental to human health during the construction process of FRP fishing vessels. Especially, the high disposal cost and the limitation of recycling technology in the disposal process of FRP fishing boats have elicited attention to circular economy. This research intended to grasp the management status and problems of disposed FRP fishing boats in Korea, and to assess the level of competitive advantage of FRP fishing boats' recycling technologies of FRP fishing boats based on VRIO (Value, Rarity, Imitability, Organization) analysis through domestic and foreign management policies and related recycling examples. According to the survey of 161 respondents, including the industry, stakeholders and experts related to the collection, treatment and recycling of fisheries wastes, it was revealed that FRP fishing boats' recycling technologies of FRP fishing boats are at the level of 'unused competitive advantage' that satisfied the level of value, rarity and imitability, but not the level of organization.
