Recycling of radioactively contaminated metal wasles is very attractive to reduce thc final disposal volumc of the radioactive wastes, thereby maximizing the usage of nahrral rzsuunts and minimizmg the detrimental effects of thz rzdioaclive wastes on the environment. In the recycling process, many complicated processes arc involved. Among those processes the 'surface contamination removal techniques such as physical, chemical and electrochern~calm ethods are the most critical and Ircquently applied in accordance with the contamination characteristics and the chemical compositions of the metal wastes. In this sludy, the sulfuric acid-cerium method and electmchemical methods were applied lu removc the conatiminated suhce. The results showed the surface contaminalion could he lowered to the background levcl by lhasc mclhods.

An introduction of landfill tax has been recently in issue in order to raise the financial resource for establishing waste resource-circulation society. The objectives of this study are to evaluate the plan of increasing energy recovery from waste at Incheon Metropolitan City, and to propose several points to be considered in terms of introducing the landfill tax. There are a lot of problems that impede energy recovery from waste at Incheon Metropolitan City, such as high-calorific waste from decrease of food waste to the municipal incineration plant, metals and batteries in the standard plastic garbage bag, etc. Alternative policies to solve these major problems have been drawn.

In 2002, the waste was generated about 277,533tons per day. The treatments of waste were recycling, which had accounted for almost 70%, landfill, which had accounted for 19.8%, and incineration, which had accounted for 6.5%. The energy recovery from incineration has been increased since 1995. The portion of waste in the renewable energy has been increased. Waste incineration heating system generates total 134TOE of $CO_2$ as compared to 6,800TOE of GHG from LNG boiler centralized heating system to bring 98% reduction rate of GHG emissions. We need the integrated model to examine the impacts of waste managements on economy and environments. The Asia-Pacific Integrated Model is introduced as the example of the integrated model.

After the introduction of Volume-based Waste Fee System for municipal wastes, the disposal of food wastes became an issue an issue in society. Concerted efforts among government agencies have been made to manage food wastes separately from municipal wastes. For example, the Ministry of Environment, the Ministry of Agriculture and Forestry, and the Ministry of Health and Welfare established the '5-year('98-'02) Basic Plan for Recycling Food Wastes' in September 1998. Also changes in the waste disposal system has been sought, aiming at the Resource-circulating Society.

For the development of a resource recycling society, it is important to control the generation of waste in all processes such as production, distribution, consumption and disposal, and to recycle the recyclable resources of waste instead of simply landfilling and incineration. However, in order to develop a resource-recycling society, not only emitters, businesses, and the central government, but also local governments need to work together to find a solution. Therefore, in this study, we present a promotion strategy for the development of Sejong City's resource-recycling society, taking into consideration the current situation of Sejong City as well as changes in the government's institution system. We suggest that regionally preparing recycling priority management plan, maximizing waste resource utilization, establishing recycling industry activation plan, and building a systematic and efficient recycling platform, etc.

To use of industrial wastes as sources of fertilizer, the waste materials from 75 factories through-out the country were collected and analyzed. The wastes from fermentation, paper manufacture, food processing and textile industries might be useful sources of fertilizer. They contained high organic matters, nutrients and relatively low heavy metals.

1992년 '자원절약과 재활용 촉진에 관한 법률'이 제정되었고 폐기물 관련 규제가 강화됨에 2003년 생산자 책임 재활용 제도(EPR)를 도입하였다. 하지만 비데시트 내부에 부착된 열선의 누전방지를 위하여 은박지 및 비데 상하면을 강력본드로 접합시키고 있다. 이 점이 재활용에 많은 어려움으로 되어 일부는 재활용되거나 폐기되고 있는 실정이다. 이러한 유효자원이 폐기되고 있는 문제점을 해결하기 위한 방안으로서 열선과 플라스틱을 자동분리 할 수 있는 장치(지그)를 개발함으로써 효율적인 R&D 사업을 제시하고 문제점을 해결할 수 있다. 이에 가정이나 생활현장에서 폐기되고 있는 자원을 회수할 수 있는 기술을 제공하고자 한다. 본고에서는 필자가 현장에서 근무하면서 터득한 폐기되고 있는 생활 폐기물인 비데두껑을 이용한 환경개선과 소재활용을 목표로 열선과 플라스틱 수지를 효과적으로 분리시킬 수 있는 기술을 적용시킴으로써 수입 대체 소재 재활용 국산에 이바지 하고자 하였다.
