Although Japan, Korea, and Taiwan are all East Asian countries, there are marked differences in the recycling policies, motivations, and methodologies of each country. One reflection of differences is the approaches each country has taken toward the OECD proposal for Extended Producer Responsibility (EPR). I consider the relationship of local governments and producers for Japan, Korea, and Taiwan from the perspective of EPR. First, I provide an outline of the establishment of waste home appliances (WHA) recycling systems. And then, consider the responsibility of related subjects. Lastly, I prepare the differences of EFR concept of each country.

This paper deals with a closed-loop remanufacturing system with one manufacturer and one remanufacturer. The manufacturer sells new products bearing the 'Extended Producer Responsibility (EPR).' It is assumed that the manufacturer's collection rate of used products depends only on the buy-back cost, while that of the remanufacturer depends on the minimum allowed quality level of used products in addition to the buy-back cost. Through the development of mathematical models with the objective function of maximizing profit, we study an efficient operation policy of each party. The decision variables are the unit selling price of new products and remanufactured products, the unit buy-back cost of the used products of the manufacturer and remanufacturer, and the minimum allowed quality level. The validity of the model is examined through numerical examples and sensitivity analysis.

'생산자책임재활용제도'는 제품생산자나 포장재를 이용한 제품의 생산자에게 그 제품이나 포장재의 폐기물에 대하여 일정량의 재활용의무를 부여하여 재활용하게 하고, 이를 이행하지 않을 경우 재활용에 소요되는 비용 이상의 재활용 부과금을 생산자에게 부과하는 제도이다. EPR(Extended Producer Responsibility)의 개념은 종전의 생산자들은 재활용이 쉬운 재질 구조의 제품을 생산하여 이를 판매하는 시점까지만 책임을 지고, 사용 후 발생된 폐기물은 소비자의 책임이었으나, 이제는 사용 후 발생되는 폐기물의 재활용까지 생산자의 책임으로 범위를 확대한다는 의미로 자리매김하고 있다. 우리나라의 경우 완전히 새로운 개념의 제도가 아니라 이미 생산자책임원칙에 의해 '92년부터 운영해 오고 있는 예치금제도를 보완 개선하여 '03. 1. 1일부터 시행하고 있는 상황이다. 본 고에서는 EPR 제도의 현황 및 성과에 대해 포장재 재활용을 중심으로 살펴보도록 한다.

The introduction of Extended Producer Responsibility(EPR), voluntary agreements and operating were analyzed in this study. The voluntary agreement to participate in the manufacturers, recyclers and management reporting agency data and literature data to verify through research and analysis assessing the performance of the management plan for this system was analyzed. The effectiveness of Voluntary Agreement(VA) on waste analysis system of voluntary agreements with the voluntary agreement of waste reduction savings exemption amount and reductions in greenhouse gases, such as comparison and understanding of business organizations participate waste recycling effects were verified. The Voluntary Agreements as a means of future regulatory system for the ongoing operation of the waste recycling operations and systems effectiveness analysis of the problems appearing in operators and manufacturers suggest ways to improve it.

As a practical means to upgrade urban sustainability, this paper focuses on resource cyclical systems concerned with the waste of electric and electronic equipment (WEEE) in Korea. Borrowing System Dynamics concepts and approaches, it examines behavioral changes of WEEE dynamics to observe whether the existing management methods can be readjusted. The measurement is based upon both reuse and material and thermal recycle simulation works in the individual stage of WEEE discharge, collection, and treatment, going beyond the traditional recycle-only customs. This research estimates that the newly introduced Extended Producer Responsibility (EPR) system would definitely exert a significant impact on the final stage of WEEE treatment, decreasing the final treatment volume in the first half of the research period. The trend, nonetheless, would be reversed in the second half, mainly owing to the additional waste volume originated from the local government and recycling center. Sensitivity analysis poses, among others, that the local government-supported reuse center should take charge of a pivotal role in the long run. The research also shows that sufficientand necessary conditions for the WEEE management and treatment should be given to the combined efforts, both from the private sectors and the public domains. Based on these research findings, the paper recommends that key stakeholders including the producer and the public organizations should devise how to jointly carry out specific agenda centered around partnership or network buildings.

Plastic supply and recycling are increasingly becoming matters of social concern. In our country, Extended Producer Responsibility(EPR) system has been adopted in 2003 to expand recycle and reuse of waste resources at producer side, and due to expansion of the EPR system, amount of the mixed plastic waste generation has been drastically increased. Plastic-plastic separation is most fundamental technique to achieve effective plastic recycling. This paper reviews recent developments in plastic-plastic separation techniques and describe future tasks. The mechanisms of each separation which contain gravity separation, electrostatic separation, flotation, and separation of automotive shredder residue are described, and commercial scale and lab-scale results are introduced.
