Remanufacturing is one alternative to conserve the good environment of our earth and to save the production resources and manufacturing energy. To make active remanufacturing in Korea we have to prepare basic rules to support the collaboration among the original manufacturing, remanufacturing, and repairing companies. Basic rules for active remanufacturing can be established by the analysis of recently environments of remanufacturing procedures and the relationship among the main constituents.

Remanufacturing is a series of industrial process by which retired or non-functional products are restored to a like-new condition. The remanufacturing industry provides much more economical and environmental benefits in view of significant materials and energy savings than existing material recycling way. It also has an effect on the substitute of natural resources, and gives the opportunity of high employment creation due to its highly labor intensive work. This paper thus presents the features of remanufacturing and its various benefits, and current status of domestic and overseas remanufacturing industry including USA, Europe, Japan and China. Furthermore, three major tasks for promoting the remanufacturing industry in Korea have been proposed based on the analysis of remanufacturing activities, technologies and related system in advanced countries.

Due to environment problems in end of Life Vehicle in the country, the interest in remanufacturing is heightened than ever. In this study, it is important to quantitatively evaluate the economic effect of the introduction of the automotive remanufacturing business and analyzed cost-benefit for the three species of bumpers, doors, fenders, which is relatively lower remanufactured automotive component. The results showed that cost-beneift of each parts were analyzed 54,000 per one part, and if remanufacturing were 50%, benefits were to occur with a profit of 226,060 won. Thus, remanufacturing of bumpers, doors, fender resulted a significant benefit, and then it is possible that remanufacturing company have enough economic value for remanufacturing.

This paper considers a remanufacturing and purchasing planning problem, in which either used products(or wastes) are remanufactured or remanufactured products(or final products) are purchased to satisfy dynamic demands of remanufactured products over a discrete and finite time horizon. Also, as remanufactured products are purchased more than or equal to a special quantity Q, a discount price policy is applied. The problem assumes that the related cost(remanufacturing and inventory holding costs of used products, and the purchasing and inventory holding costs of remanufactured products) functions are concave and backlogging is not allowed. The objective of this paper is to determine the optimal remanufacturing and purchasing policy that minimizes the total cost to satisfy dynamic demands of remanufactured products. This paper characterizes the properties of the optimal policy and then, based on these properties, presents a dynamic programming algorithm to find the optimal policy. Also, a network-based procedure is proposed for the case of a large quantity of low cost used products. A numerical example is then presented to demonstrate the procedure of the proposed algorithm.

Recycling involves processing used materials into new products and remanufacturing is an industrial process in which worn-out products are restored to like-new condition. Recycling and remanufacturing industry is environmentally and economically important industry and provides significant benefits to prevent waste of potentially useful materials and reduce energy usage. The purpose of this research is to investigate the trend of recycling and remanufacturing industry in Korea and other countries like Germany, Japan and America. The yield information is generally quite valuable to promote green growth industry as an important alternative in the 21st century.

The rise in population and the increase of urbanization and industrial growth has resulted in an ever-increasing volume of municipal solid waste that must be regularly collected, transported, and ultimately disposed of. Therefore, over the last decade the public, commercial and legislative awareness of environmental issues has been increased dramatically on earth particularly some industrial countries which has a shortage of landfill capacity. A quality, cost and delivery lead-time are usually considered as the competitive factors for each industry. However, the concepts of environmental issue are emerging common terms and concerns more seriously. More attention than ever is being focused on the recycling and source reduction techniques to reduce the total volume of waste. Unfortunately, however, a shortage of landfill capacity and increasing disposal cost requests a fundamental solution about the environmental issue. That is the remanufacturing which allow manufacturers to minimize waste, production cost and to turn end-of-life product into a profitable product. The objectives of this research were to growth the remanufacturing system by suggesting issues and implementation methods for the remanufacturing. In order to accomplish these objectives, we introduced backgrounds of appearance and benefits of the remanufacturing.

As one of the developing countries in the world trade market, we have to apply the environmental concept at the development of a product for environmentally conscious manufacturing system(ECMS). Traditionally, production control model has been studied based on a new product manufacturing environment. However, ECMS such as a remanufacturing system should be developed and implemented for highly competitive environment in 21C. The objective of this study was to extend the research of production control model by applying it at the remanufacturing environment of ECMS and to test the applicability of current production control model at the remanufacturing environment by the simulation experimental study.

As production, distribution, consumption and processing increase with the development of industrial societies, the importance of resource depletion and environmental problems is increasing day by day. This has led to increased research and interest in remanufacturing that can satisfy both environmental and economic aspects. Currently, the remanufacturing industry is progressed in Korea with automobile parts with as the central figure, and it needs to be expanded into various areas. In this study, the failure type analysis and FMEA were performed on the hydraulic pumps used in construction and industrial sites for the development of the standard remanufacturing process plan, and the actual disassembly and reassembly process was carried out. Remanufacturing products were manufactured through the analysis contents and drawing process, performance tests were conducted in accordance with RS B1501 criteria to evaluate performance, and all of these products passed the test criteria.

Remanufacturing is one of the most important resource recycling technology in response to resource depletion and environmental pollution. Domestic remanufacturing industry don't invigorate compared to other advanced countries because of low price and reliability of remanufactured product. In this study, remanufactured hydraulic pump and solenoid valve were evaluated durability by accelerated life test. In order that standard remanufacturing process was developed by core analysis and failure mode and effect analysis. And cores were remanufactured by standard remanufacturing process. For accelerated life test, the evaluation item and criteria were deduced by results of FMEA, reliability standards and enterprise interior criteria. To evaluate durability of remanufactured product, the remanufactured hydraulic pump and solenoid valve were evaluated performance after accelerated life test and the results were satisfied with criteria. This study showed that remanufactured products have a similar level of durability to new products by definition of remanufacturing.
