  • Waste electrical and electronic equipment(WEEE or E-waste) is one of the fastest growing waste stream in Korea. The proper management of such equipment has become of major concern for solid waste professionals because of the large growth of the waste stream and the presence of a myriad of toxic materials with in it. In this paper in order to review the recycling system and recycling industries of the E-waste in Korea, the main frame concerning recycling of "Act on the Resources Recycling of Waste Electrical Electronic Equipment(WEEE) and End-of-life vehicles", recycling system, current recycling status, estimation of the E-waste generation, material flow of the E-waste, economics of PCB and recycling industries of the E-waste were surveyed.

  • In order to prospect current recycling status in Korea, legislative system and policies relating to recycling, wastes generation and recycling rate were reviewed. Approximately 260,400 ton/day of wastes was generated in 2001. 48,400 ton/day of household waste and 212,000 ton/day of industrial waste. During the last ten years, waste management laws such as waste disposal law, recycling law and environment friendly industry law were prepared. In this article, concerning over waste generation and recycling, recycling law, Extended Producer Responsibility System and the problems and technological developments associated with recycling were summarized.

  • In order to review the recycling status of urban mine resources in China, recycling of ELV(End of Life Vehicles), E-waste(WEEE) and nonferrous metals were surveyed. Number of the sales volume of the new vehicles were over more than ten million and number of discharge vehicles are increasing now. However, recycling system has not been managed smoothly in China. Though usage of home appliances in urban is similar with advanced countries, there are significant differences in rural community. In the other hand, China is the country with the largest E-waste import in the world. Production and consumption of the nonferrous metals are increasing year by year in China, but recycling of metals is not enough.

  • According to the statistical data of the Ministry of Environment, 47million tons of construction waste were generated, and 96.7% of them was recycled in 2005. However, the recycled products seem to be remained under low quality. Because mixed demolition and construction waste, so called DC Waste, including concrete, brick, plaster, lumber, plastics building materials, paper and some dirt and stone, is very variable and difficult to estimate its exact composition, it is regarded as having little or no value to the construction industry. 'The Research group on recycling of construction waste' was started by the Housing & Urban Research Institute(KNHC), which is sponsored as a large scale national project by the Ministry of Construction and Transportation. This research group intends to establish recycling system through planing, processing, developing practical technology, and eventually contribute to save natural resource and to vitalize the industry. In this paper an overview of DC waste management and recycling technology is given in some detail. Particularly, "recycling law of construction waste" and recent research trends on recycling of construction waste are discussed.

  • In order to review the recent technological progress and issues on the urban mine resources recycling in Japan and Korea, recycling process of the ELV(End of Life Vehicles) and E-waste(WEEE) were studied. Although technological level for processing of the ELV and E-waste is almost similar in both countries, the treatment of hazadous materials of ELV such as freon, air bag and ASR is unsufficient in Korea. In the E-waste recycling, the technological level is deeply different according to the enterprise size in Korea. Finally, the big R&D project on recycling of urban mine resources sponsored by government in both countries were discussed.

  • 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.

  • Sustainable supply of minerals and energy is global problem. Metals and energy consumption in the world has increased with economic growth. Currently more than 40 metals are systematically extracted and used in many different fields in civilized society. Recycling and reuse have become very important because recycling contributes to supplying the materials and protecting the environment of society. It is not realistic that all waste materials are capable of being recycled, because recycling metals have fundamentally been competing with primary production. In this point of view, prior to discuss on current recycling technology of waste resources in Korea, world wide trend and Korean recent activity in the supply-demand far minerals and energy resources are reviewed.

  • The status of waste generation and recycling in 32 countries in the European Union (EU), Japan, and the United States was investigated and summarized to encourage overseas market expansion for domestic urban mining industries. Among the 32 EU countries, Germany has the highest amount of material consumption and generates the largest quantity of waste. Minerals such as mine and soil wastes constitute the largest type of waste in the EU. With respect to waste treatment techniques, landfill and recycling are applied to 39% and 38% of the waste, respectively, implying the necessity to promote recycling. Japan's total waste generation declined recently to less than 400 million tons. The largest amount of waste is generated by the manufacturing industries. The proportion of total recycled waste is estimated to be slightly over 50%, but the proportions are greater than 90% for metal scrap and 60% for waste plastics. The amount of waste produced in the United States recently exceeded 265 million tons; 52.1% of the waste is landfilled, while only 25.1% is recycled. Therefore, the recycling industry has to be developed further.
