This paper focuses on the pilot-scale investigation of direct recycling of electric arc furnace (EAF) stainless steelmaking dust. The direct recycling of EAF dust is to make pellets with the mixture of the dust and the reducing agent carbon, then introduce the pellets to the EAF. The valuable metals in the dust are reduced and get into the steel as the alloying elements. Experiments simulating direct recycling in an EAF were performed using an induction furnace. But it seems difficult to reduce all metal oxides in the dust so that some metal reducing agents added in the late stage of reduction process. The valuable metals in the dust were reduced partly by carbon and partly by metal reducing agent for the economical concern. The recovery of iron, chromium and nickel from the flue dust and the amount of metal oxides in the slag were measured. The results showed that the direct recycling of EAF stainless steelmaking dust is practicable. It wes also found that direct recycling of flue EAF stainless steelmaking dusts does not affect the chemistry and quality of stainless steel produced in the EAF. It is benefit not only for the environmental protection but also for the recovery of valuable metal resources in this way.

Although the rare earth elements (REEs) recycling industry is expected to increase worldwide in hightech industry, regulations for worker safety have yet to be established. This study was conducted to understand the potential hazard/risk of REE recycling and to support the establishment of regulations or standards. We review the extensive literature on the toxicology, occupational safety, and health issues, and epidemiological surveys related to the REEs, and propose suitable management measures. REE recycling has four key steps such as collection, dismantling, separation, and processing. In these processes, hazardous substances, such as REEs-containing dust, metals, and chemicals, were used or occurred, including the risk of ignition and explosion, and the workers can be easily exposed to them. In addition, skin irritation and toxicities for respiratory, nervous, and cardiovascular systems with the liver toxicity were reported; however, more supplementary data are needed, owing to incompleteness. Therefore, monitoring systems concerning health, environmental impacts, and safety need to be established, based on additional research studies. It is also necessary to develop innovative and environment-friendly recycling technologies, analytical methods, and biomarkers with government support. Through these efforts, the occupational safety and health status will be improved, along with the establishment of advanced REE recycling industry.

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.

폐기물 재활용은 폐기물 관리에 있어서 감량화 다음으로 중요한 개념이다. 폐기물 중 특히 포장폐기물은 재활용시 환경성과 경제성을 지니고 있어 재활용이 용이하다. 그러나 그 중에서도 포장폐기물 중 점점 더 증가 추세에 있는 화장품용기는 재활용품목이 아닌 일반폐기물로 분류되어 버려지고 있다. 화장품 산업의 규모와 비례하여 나타나는 산업쓰레기의 처리문제는 심각한 환경문제를 유발하는 요인이 되고 있다. 또한 화장품은 대부분 플라스틱과 유리 등 복합재료로 만들어져 있어 재활용하기가 어렵다. 화장품용기는 분리수거 하기도 힘이 들고 분리 수거한 용기들도 재질이 복합적이기 때문에 재생이 어려운 경우가 많다. 이에 본 연구에서는 현재의 화장품 용기 재활용과 관련하여 갖고 있는 소비자들의 의식을 조사하였다. 조사결과에 대한 용기 재활용을 위한 증진방안은 다음과 같다. 첫째, 화장품 용기 관련 법 및 제도개선 분야로 화장품법 및 예치금, 부담금 제도 개선과 화장품 용기류 재활용을 위한 기술개발, 리필제품의 확대, 화장품용기만의 회수체계 확립, 생산자의 화장품 재활용 적극 참여 유도가 이루어져야 한다. 둘째, 화장품 용기 디자인 개선 분야로 용기 재질 단순화 및 규격화,화장품 라이프 사이클 확대, 재활용 가능한 재료 선택, 화장품 용기의 비용감소, 기업의 재활용 용기 개발 적극 참여가 이루어져야한다. 결론적으로 포장폐기물 중 화장품 용기의 재활용을 증진하기 위해서는 관련 제도 개선 뿐만 아니라 정부와 기업의 적극적 참여,그리고 소비자들의 적극적 재활용의식이 종합적으로 발전을 이루어야 한다. 그리고 무엇보다도 기업에서 화장품 품질 개선을 위한 투자와 개발 뿐만 아니라 화장품 용기의 환경친화적인 용기 개발을 위하여 많은 노력이 우선시 되어야 할 것이다.
