Prior to discuss on recycling status and future prospects for the non-ferrous metals in the Korea, Japan and U.S.A. respectively, worldwide resources of non-ferrous metals and characteristics with recycling of non-ferrous metals are reviewed. In case of recovery non-ferrous metals, recycling of automobile shredder dust and E.A.F. dust are illustrated. Finally, the problems and technological developments associated with recycling of non-ferrous metals are summarized.

최근들어 유리병 재활용에 대한 관심이 고조되고 있다. 이것은 자원의 절약과 쓰레기 감량화의 관점에서 볼때 유리병 재활용의 중요성이 점점 더 크게 부각되고 있기 때문이라 생각된다. 본 논문에서는 국내 유리병 회수 재활용 체계의 현황과 문제점을 분석해 보고 외국의 재활용 현황을 요약하였다. 또한 시민들의 의식 조사에 기초하여 유리병의 재활용 증진을 위한 법적, 제도적 개선방안을 제시하였다.

The purpose of this study was to ensure that materialism is an important explanation variable not only for consumption behavior of clothing but also for recycling attitude and behavior of clothing. Therefore, we investigated the influence of materialism and environment consciousness on recycling attitude and behavior of clothing. A total of 210 survey questionnaires were collected. The results revealed that materialism didn't directly affect recycling attitude, but that the happiness dimension of materialism negatively affected environment consciousness and that materialism indirectly affected recycling attitude and behavior via environment consciousness. Environment consciousness dimensions partially affected recycling attitude and behavior of clothing. Recycling altitude positively affected recycling behavior.

이 글은 현재 국내 리튬이온전지 상용 재활용 공정을 정리하고, 리튬이온전지 재활용 공정의 새로운 방향을 제시한다. 대표적인 리튬이온전지 재활용 업체인 (주)성일하이텍은 10년 이상 리튬이온전지 재활용 공정을 성공적으로 운영해 왔으며 최근 많은 재활용 업체 및 배터리 제조업체들이 새로운 재활용 공정을 제안하고 개발하고 있다. 새로운 재활용 공정에서는 리튬 가격의 급격한 상승으로 니켈과 코발트보다 먼저 리튬이 회수되고, 금속 황산염 용액을 최종 제품으로 배터리 제조업체에 공급하는 특징이 있다. 향후 대량으로 발생할 폐전지 처리를 위해 기존 공정이 개선될 필요가 있으며, 폐기된 자동차와 함께 유입되는 성분들과 리튬이온전지의 새로운 첨가제는 향후 리튬이온전지 재활용 공정에서 주요 공정효율 저감 요인이 될 수 있다.

본 고는 일본(日本)의 자동차리싸이클링 시스템과 해체업계의 경영통향을 조사하여 일본(日本)의 자동차리싸이클링산업의 전망을 고찰한 것이다. 먼저 2005년도부터 시행된 자동차리싸이클링법의 내용과 시행상황을 검토하고, 일본(日本)의 자동차리싸이클링의 전체상을 파악 분석하였다. 2007년도 553만대가 말소등록 되었으며, 이중 161만대가 중고차로서 수출되고 392만대가 폐차(해체)되었다. ELV 리싸이클링율은 94.4%이다. 중고차수출은 매년 신장하고, 자동차리싸이클링에 차지하는 비중이 크다. 해체업계의 경영동향을 파악하기 위하여 서일본(西日本) 오토리싸이클링 주식회사(WARC)가 회수한 재사용 재활용 부품과 소재를 현장조사하고, 리싸이클링시장의 기복과 중고부품 판매망을 조사하였다. 끝으로 현재 진행 중인 자동차리싸이클링법의 재검토 및 수정 보완에서 강조되고 있는 재사용부품의 이용촉진과 자동차리싸이클링의 고도화(레어메탈의 회수 향상)에 관해서 언급하였다.

As the scarcity of natural resources has become apparent, the recycling industry has emerged as a promising one for its growth potential. Yet, the recycling industry still remains undeveloped and inefficient for various reasons. In this study, we focus on firms' recycling processes to understand the current status of recycling firms' value creation activities. With respect to the adopted recycling processes, we empirically investigate the differences in firm characteristics and firm performance. We use the data from Keco (Korea Environment Cooperation) which annually conducts a survey of recycling firms in Korea. We exclusively consider the whole group of plastic recycling industry in order to control for a possible bias in firm performance, stemming from the heterogeneity in processing and recycling of materials other than plastics. We review the descriptive statistics from the sample firms and conduct a series of hierarchical regression analyses. The results show that most of the firms in this industry adopt physical transformation processes with a low-level technology. These firms with physical transformation processes are smaller in size and produce entry level items which do not secure higher margins. The results indicate that the recycling industry largely comprises low value added firms which lack economies of scale and resources for R&D. For the stable growth of the industry, recycling firms must create sustainable values through implementation of technology-driven processes and improvement in product quality. In addition, the government should help build a reliable reverse logistic network, lower the entry barriers, and provide necessary funding for the SMEs in the recycling industry.

This study focused on recycling behavior and related variables. Specifically it aims 1) to investigate the level of recycling attitudes and behaviors 2) to find out variables related to recycling behavior, Data were collected with questionaire from 248 wives in Kwangju city. The results can be summerized as follows: The sorting behavior of waste was higher than median but active recycling behavior was lower than median. The recycling behavior was facilitated by wives' high age lower education level apartment dwelling and part-time job. In addition to motivate the recycling behaviors various implications discussed.

The recycling cell formation problem means that disposal products are classified into recycling product families using group technology in their end-of-life phase. Disposal products have the uncertainties of product condition usage influences. Recycling cells are formed considering design, process and usage attributes. In this paper, a new approach for the design of cellular recycling system is proposed, which deals with the recycling cell formation and assignment of identical products concurrently. Fuzzy ART neural networks are applied to describe the condition of disposal product with the membership functions and to make recycling cell formation. The approach leads to cluster materials, components, and subassemblies for reuse or recycling and can evaluate the value at each cell of disposal products. Disposal refrigerators are shown as an example.
