Owing to technological advancements and energy-saving policies, the demand for LED is increasing, leading to rapid industry expansion. Consequently, efficient recycling of accumulated LED waste has become a growing social concern, and current recycling status of LED waste resources and future directions were reviewed. Currently, waste LED recycling is focused on Ga recovery. Therefore, the development of integrated recycling technologies such as pre-treatment and concentration/recovery of high valued materials is necessary. In this study, we investigated the status and recycling technologies of waste LED and presented prospects.

In general, recyclable items are separately discharged from households and then, hand-sorted into different types of valuables at materials recovery facilities (MRF). However, most of residues after hand-sorting are finally end up with landfill and/or incineration due to lack of separation technologies and economical reasons. In the present study, physical properties on recyclable items obtained from an MRF are investigated to improve the recovery of valuable items. The results of physical compositions based on the sizing tests are also presented.

Number of vehicles in Korea is gradually increasing and it exceeded 16 million in 2007. Holding of vehicles is connected to disposal, owing to this reason the importance of ELVs recycling has been emphasized. The recycling of ELVs makes the disposal of ELVs easier as well as protects environment and it has the alternative effect economizing the insufficient resource. This study was carried out to evaluate the economic effect of recycling of ELVs compared with disposal of ELVs. The analysis showed that recycling process makes a profit in comparison to the disposal of ELVs. Therefore the government has to consider establishing the regulation related to recycling of ELVs or materials and car manufactures have to develop the efficient dismantling and recycling methods.

Development of technology makes LED an economical option because of lower energy consumption and better environmental impact. Because higher consumer demand the LED market is expanding rapidly due to its environment-friendly advantages. Expansion of LED application, development of various fusion technologies, the emergence of new markets, and the large-scale expansion of markets would lead to a large volume of e-waste generation with valorization potential. Currently, most of the generated waste being that landfilled and incinerated due to the absence of technology and management system. In this paper, we review the current status of LED waste recycling and analyzes the available recycling technologies.

The importance of recycling came to the fore by increasing of waste electrical and electronic equipment(WEEE) generation. Small WEEE recycling in particular represents a big challenge in Korea because it has various items and components. Main materials of small WEEE are typically well known for metals (copper, iron, aluminum, etc.), PCBs and plastics. Not only Korea but also overseas, the laws for small WEEE were in effect in order to recycle effectively, but the technology is not catched up with the regulation which has to recycle an allocated account of WEEE. In addition, recycling technologies and processes for small WEEE are not developed enough to recycling center properly. In that sense, if we develope the recycling process, have not only technology competitiveness but also resource conservation, improving the environment and economic profits. Therefore, through the analysis of economic value of recycled small WEEE, and current technologies both domestically and internationally, we design conceptual recycling process of small WEEE, and consider the way forward.

Recycling of spent autocatalyst that includes the platinum group metals (PGMs), namely palladium, platinum and rhodium, is a very profitable endeavor. In order to ensure an efficient promotion of an appropriate policy-making and the technical development of the recycling process of spent autocatalyst in Korea, the generated amount, trading conditions, and recycling technology for spent autocatalyst were surveyed. The generated amount of spent autocatalyst was estimated by analyzing the domestic statistical data of registration & disuse of automobiles and the records of autocatalyst installation to new cars. The review of the recycling technology was carried out by surveying the recycling processes of 'Heesung PMTech Ltd.', which is the largest company in the recycling industry for spent autocatalyst in Korea. In addition to the above, some policy suggestions for the improvement of recycling industries for spent autocatalyst were offered.

본 연구는 국제환경규제에 따라 폐자동차의 재활용율 향상을 위한 재활용 부품 우선순위를 도출하고, 폐시트 등 부품 재활용에 의한 환경성을 평가하기 위하여 폐차 해체시스템 전과정평가를 수행하였다. 연구결과 차피의 고철을 재활용 할 경우에는 지구온난화와 오존층파괴에 큰 환경이득을 얻을 수 있으나 폐시트를 폴리올 원료로 재활용할 경우에는 많은 자원의 사용으로 오히려 소각으로 인한 환경부하보다 지구온난화와 오존층파괴, 광화학산화물생성 등의 부하를 증가시키는 것으로 나타났다. 그러나 폐차의 95% 이상을 재활용 및 회수하기 위해서는 분해시간 및 시장성, 기술현황 등을 종합하여 고려하여야 하며 재활용이 곤란한 유리와 같은 다른 부품과 함께 시트의 물질재활용도 반드시 포함되어야 될 것으로 사료된다. 처리와 재활용에 따른 환경성을 비교한 결과 재활용이 필요한 부품은 시트와 유리가 가장 시급하며, 배터리, 혼합플라스틱도 재활용시 환경친화적 공정개발이 필요한 것으로 도출되었다.

폐기물의 양이 급격히 증가하고 있는 현재, 국내는 물론이고 전 세계적으로 자원의 고갈에 대한 심각성을 인식하고 폐기물을 재활용하여 가능자원으로 만들기 위한 방법을 모색하고 연구하는 등 미래자원을 확보하기 위한 노력을 꾸준히 하고 있다. 하지만, 폐철, 폐지, 폐플라스틱, 폐유, 폐타이어 등의 폐기물에 대해서는 많은 관심을 가지고 재활용 기술을 연구하는 등 그 중요성에 대해 인식하고 있는 반면, 유리제품의 재활용에 대해서는 그 중요성이 인식되지 못했다. 그래서 월간 ‘재활용’지에서는 폐유리병 재활용 현황, 기술 등에 관한 특집기사와 더불어 유리제품 재활용에 대한 인식을 고취시키기 위해 현장의 목소리를 듣고자 유리재생원료(cullet)를 생산하는 쎄로라인을 찾아 업체탐장 코너에 소개한다.
