우리나라를 포함한 많은 국가들에서 향후 원전 해체로 저준위폐기물이 대량으로 발생할 전망이다. 본 논문에서는 미국의 저준위방사성폐기물 처분 관련 규제 기준을 분석하고, 특히 원자력발전소의 운영 및 해체를 포함하는 전주기에서 발생하 는 폐기물의 처분 옵션을 확장하는 방안으로 사용되고 있는 저준위방사성폐기물의 블랜딩에 대해 검토하였다. 2007년 미 국 NRC는 미국 저준위폐기물 관리 프로그램에 대한 전략분석 결과, 방사선위험도와 성능평가에 기반한 새로운 저준위폐기 물 관리 규제의 필요성을 제기하였는데, 특히 방사성핵종 농도가 다른 폐기물의 블랜딩을 처분에 대한 옵션을 다양화할 수 있는 안전한 방안으로 제시하였다. NRC는 블랜딩을 처분에 적합하도록 방사성핵종의 농도가 다른 저준위폐기물을 비교적 균일하게 혼합(mixing)하는 것으로 정의하였다. 2015년 2월 농도 평균과 포장에 대한 NRC BTP의 개정판으로 공표된 블랜 딩에 대한 구체적인 기술요건을 분석하였고 국내 해체폐기물에 대한 적용 방안도 예시하였다. 대량으로 발생할 해체폐기물 에 대해 블랜딩과 농도평균을 적용하면 처분 효율성을 향상시킬 수 있다. 바이오쉴드 콘크리트에 대한 농도평균 적용에 대 해 예시하였다.

Waste management in Jeju Province, Korea, has recently emerged as an urgent problem. The increasing waste discharge requires more landfills but, since it is an island, the available land is restricted. Accordingly, an efficient waste management urgently requires environmentally sustainable policies. In this article, the waste discharge characteristics (such as the amount of waste, its composition, etc.) of Jeju Province have been compared with those in the rest of Korea. The current industrial waste management of two cities on the Island, Jeju City and Seogwipo City, has been also analyzed to suggest policies for an efficient management. The local government’s endeavor to enhance environmental awareness of the community has been known to reduce the private cost of policy compliance, and have individuals recognize the results of their policy compliance. Policies to achieve the above are then proposed.

With the upcoming enforcement of the Fundamental Law of Resource Circulation in January 2018, changes are expected to occur in waste management policies. Until now, South Korea has worked hard to prevent waste generation and improve recycling. The recycling rate has improved, but recyclables are not considered high-quality. To resolve these issues in its member states, the EU is promoting resource efficiency policies. Their plan is to integrate the environment with the economy, achieve economic growth, and create jobs. A circular economy has also been adopted as a strategy to promote the resource efficiency policies. The key content of the strategy consists of an action plan and a waste law revision. Goals for the recycling of wastes by 2030 have been set in laws revised through this strategy, which also includes recycling evaluation standards and calculation methods. For Korea to cultivate a resource circulation society in the future, the EU’s resource efficiency policies and strategies must be preemptively implemented in a manner that suits the situation in Korea, and terms must be defined and standards established for recycling.

In this research, the upgrading technology and policy trends for biogas were examined with a focus on the European Union (EU). Depending on the capacity of the biogas upgrading facility investment costs are different. In addition, biogas upgrading technology-specific energy demand is lowest in the amine scrubber process. Organic waste met the sustainability criteria. Also, the energy content was four times larger, and the results showed that the utilization value was significant. Through cogeneration, and it can secure various markets. Because of these advantages, various policies are being promoted in the EU. In the future, South Korea needs to model its biogas policy after the upgrading technology and policy trends in the EU, and it should strive to create a market for biomethane.

Waste recycling comes to the fore because of resources depletion and environmental pollution. ‘End-of-Waste (EoW)Criteria’ are reported to help improve recycling by determining when a waste ceases to be a waste, independently fromthe waste management option, and guarantee higher quality of secondary materials by environmental requirements of thesematerials. This approach can reduce consumption of natural resources and decrease the amount of waste sent for disposal.The aim of this study is to comprehensively review and analyze the current criteria on the End of Waste in foreigncountries. In addition, this paper suggests policy implications to promote more recycling and use of waste materials asresources by comparing domestic and foreign regulations. Based on the research, domestic EoW criteria need to be morecleared in the aspect to hazard assessment, ensuring a high level of environmental protection and solving legal uncertaintyhindering the development of the recycling sector.
