The main purpose of this research was to develop upcycled DIY kits made from subway billboard material to make living products. This study was conducted based on the following four stages of design process: research and analyses, DIY kits' design direction establishment, completion of DIY kits, and implementation and evaluation. Through this study, we developed DIY kits for pouches, tissue cases and pencil cases. In the implementation and evaluating stage, we chose to make pouches because it includes zipper attachment process. Implementation was conducted by recruiting four high school students and four female adults. As a result, we found the following: First, the participants were able to make pouches in less than an hour. Second, pouch making has a moderate degree of difficulty. Third, video instructions should be slowed down. Forth, materials need to be improved. Fifth, environmental awareness was improved by using unfamiliar subway billboard materials. The upcycled DIY kits, developed as a result of this study, can be used as eco-friendly education sources for secondary school students as well as for adults' healing hobby.

The purpose of this study was to propose up-cycling fashion designs, based on guidelines derived from up-cycling fashion brand products and their required elements of the design. The study thus categorized required elements into environment, significance, economy, function, design, and material, then extracted a set of design guidelines. The guidelines for waste resource-based up-cycling fashion design include the followings: First, authenticity, taking mutual environmental relations into account. Second, rarity of products beyond the domain of standardized ready-made goods thanks to manual operation. Third, storytelling, reflecting the consumer history. Fourth, sustainability to signify the circulation of matters. Fifth, experimental characteristic to fulfill creative innovation. Sixth, changeability through interactions with wearers. The investigator decided design concepts based on them and created up-cycling design works with waste plastic bags, shirts, stockings, neckties, outdoor mats, and backpacks in a variety of formative expressive techniques.

This study explores application of upcycling design methods in structural transformation of second-hand denim clothing, aiming to achieve sustainable design objectives. By drawing inspiration from Liu Qing's research methods in the field of circular utilization of denim clothing, this study collected and analyzed cases of structural transformation of used denim clothing from 2020 to 2023. It summarized structural transformation design methods for used denim clothing. Through the development of design works, this study aims to find out the best upgrading and renovation design strategy by applying the method of structural renovation design. This study aims to support the development of a sustainable fashion industry and promote recycling and upcycling of discarded clothing fabrics, thereby reducing resource waste and environmental impact.

A feasibility test was carried out for upcycling of waste jelly-filled communication cables together with the development of environmentally friendly processes and equipments. High pressure water injection is proved to be an exceptionally environmentally friendly and highly efficient mechanical process. A batch-type cable barking equipment is designed and built on the basis of computational fluid dynamics modelling. It is optimized in terms of energy consumption and productivity with very high copper recovery of 99.5%. Copper nano-powder is prepared by an electrical wire explosion in ethanol media in order to improve the value of final products, and the preliminary economical assessment is also conducted.

This study is the 2nd report following "A Study on the Characteristics of Material in the Korean Up-cycling Fashion Brands (Part I)" that handled the development of upcycling props using the characteristics of upcycling material. The 2nd report analyzed product types and materials focusing on 21 foreign upcycling fashion brands. It analyzed the characteristics of upcycling fashion materials using the case analysis of coffee bean bag and waste denim based on external characteristics and internal characteristics. We then classified the external characteristics into environment/economic feasibility and availability/mixture and the internal characteristics into historicality/story and originality/scarcity. Five bags were designed and produced for the actual commercialization of fashion products based on such characteristics of materials, with the use of coffee bean bags and waste denim as upcycling materials. This study is differentiated from existing research by its suggestions for the utilization of fashion product upcycling coffee bean bags and waste denim. Also, upcycling fashion products could be competitive products in eco-friendliness and originality that can be a driving force for the sustainable development of fashion industry through the differentiation of existing fashion products.

Plastic's ease of processing drives its growing production, resulting in a surge of plastic waste. Addressing this issue, catalytic upcycling emerges as a promising remedy. Various metals (Ru, Pt, etc.) and supports (TiO₂, CeO₂, etc.) have been employed for the chemical recycling of polyolefin plastics. Strategies to enhance liquid fuel selectivity and minimize methane include manipulating particle size, introducing heterogeneous metals, and tuning support characteristics. Simultaneously, endeavors to optimize catalysts by reducing precious metal usage were pursued. This study explores enhancing economic viability in hydrogenolysis and hydrocracking reactions, underscoring the potential of catalystdriven upcycling to tackle plastic waste.

The purpose of this study is to develop and implement a step-by-step upcycling fashion education program that can be utilized within the local community. This program aims to provide basic data by analyzing the current state of community-based upcycling projects and upcycling center programs. To achieve this, the study first examined the meaning and value of upcycling in fashion through literature research and explored upcycling projects and programs in connection with local communities. Subsequently, an upcycling fashion education program platform was developed and applied using the design thinking process. The program involved students from nine high schools in Gwangju Metropolitan City. Depending on the school's circumstances, the time and difficulty level of the upcycling education program were adjusted accordingly. A unique eco-bag making kit, using jeans developed in this study, was employed. Following the completion of the program, a satisfaction survey was conducted among 167 participating students from the high school community class. The findings indicated that the majority of students experienced an increased appreciation, attraction, and interest in upcycling products. They also demonstrated an understanding of the environmental impact of upcycling products and the distinction between upcycling and recycling. It is believed that the educational program developed in this study can promote ethical fashion and foster a sense of value-based consumption. This program can be customized and flexibly adapted to different educational levels and institutional characteristics, making it accessible to a wide range of learners.

The purpose of this study was to provide basic information on the development of local governments and upcycling industries that want to establish centers in the future. The study investigated the current situation and programs of domestic upcycling centers for regional sustainable growth. As a result of comparing and analyzing the programs operated by the upcycling centers by region, they could be classified into culture and arts experience programs, resource circulation experience programs, and environmental culture education programs according to the nature of the operation programs that are more focused on in addition to the experience and education programs reflected by each center. Among the upcycling materials and items used in the operation program, fashion-related education was being operated in a more diverse manner in the area of culture and arts experience programs. As a result of the analysis, it was found that it was necessary to establish a smooth material supply network, develop an in-depth step-by-step upcycling fashion education program, and strengthen the upcycling center program using regional characteristics. The results of this study are significant in that they provide the local governments with basic information for the establishment of upcycling centers in areas where the upcycling centers have not been established. In addition, this study presents the types and directions of programs necessary for establishing upcycling centers in the future.
