A 'Resource recycling society' is the common goal to reduce environmental impact from human activities and to conserve natural resources. The Resource-Recycling Waste Management is necessary to explicitly show objectives, and to evaluate the achievement level gained by school administration. In this paper, focusing on resource-recycling school waste management, three indicators are designed to evaluate the present conditions of school waste management, which include evaluation of school policy, waste management and education for waste management by school administration. Each indicator is made up of three or four questions that are supposed to be answered by school managers, teachers and students. Questionnaire surveys, which is based on the resource-recycling school waste management indicators, were carried out in elementary school, middle school and high school in the National Capital region. The resulting of indicators well describe the situation of school waste management among these schools. Influential strategies towards resource-recycling school waste management have been found in analysis.

자원순환기본법 시행에 따라 국가적으로 자원순환사회 발전을 위해 노력중이다. 이를 위해서는 생산·유통·소비·폐기 등 전 과정에서 폐기물 발생을 억제하고 폐기물 중 재활용가능자원이 단순히 매립·소각되는 대신 재활용되는 것이 중요하다. 하지만 자원순환사회를 만들기 위해서는 배출자. 사업자, 중앙 정부 뿐 아니라 지자체가 함께 노력하고 해결방안을 모색할 필요하다. 이에 본 연구는 국내 제도의 변화와 함께 세종시 현황 및 여건변화를 고려하여 세종시 자원순환사회 발전을 위한 추진 전략을 제시하고자 한다. 지역적으로 재활용 우선 관리 단계별 활성화 방안 마련, 폐기물 자원화의 극대화 및 재활용 산업 활성 방안 마련, 체계적이고 효율적인 재활용 플랫폼 구축 등을 제안한다. 이를 통해 자원순환사회로 도약하고 폐기물이 지속적으로 증가되고 있는 환경문제에 대한 해결책이 될 수 있을 것으로 기대한다.

Since the Framework Act on Resource Circulation was enacted in 2018, the government should establish a National Resource Circulation Master Plan every 10 years, which defines mid- to long-term policy goals and directions on the efficient use of resources, prevention of waste generation and recycling of waste. In addition, we must set mid- to long-term and stepwise targets for the final disposal rate, recycling rate (based on sorted recyclable materials and recycled products), and energy recovery rate of wastes, and relevant measures should be taken to achieve these targets. However, the current industrial waste (IW) statistics have limitations in setting these targets because the final disposal rate and recycling rate are calculated as the ratio of the recycling facility input to the IW generation. In this study, the material flow from the collection stage to the final disposal of industrial waste was analyzed based on the generation of 2016, and the actual recycling amount, actual incineration amount, final disposal amount and their rates were calculated. The effect on the recycling, incineration and final disposal rates was examined by changing the treatment method of nonhazardous wastes from the factory and construction and demolition wastes, which were put in landfills in 2016. In addition, the variation of the waste treatment charge was investigated according to the change of treatment methods. The results of this study are expected to be effectively used to establish the National Resource Circulation Master Plan and industrial waste management policy in the future in South Korea.

Most of dredged soil generating millions of tons per year is treated as a waste disposing in ocean or landfill except some part of recycling. The purpose of this study is to present the prerequisite for the use of dredged soil as a resource and analyse economic and environmental values of the recycling of dredged soil. The analysis of the economic and environmental value of recycling of dredged soil as a resource showed that several trillion won of budget can be saved in construction of disposal area or landfill and that loss of about 50 million tons of aggregates from deforestation can be restored by supplyment of dredged soil preserving a mountain as big as the Namsan(Mt.) every year. In order to utilize dredged soil in more diverse areas as high value of resource, the related domestic laws are needed to be readjusted integrating laws spreaded in different government departments and a special law is prepared and enacted.

Upcycling generally refers to the conversion of waste materials to something useful or valuable and is a useful concept that can be applied not only to the waste design industry but also to waste recycling and resource circulation. Our study highlights upcycling as the key concept for improving the value of waste by redefining the concept as "the recycling of waste materials and discarded products in ways that enhance their value." Four upcycling strategies are linked to material flow analyses conducted on waste electronic and electrical equipment, specifically waste refrigerators and waste computers, to examine the technologies available for implementation and suggest guidelines for the promotion of upcycling. The amount of waste refrigerators collected by the formal sector was 121,642 tons/y and the informal sector, 63,823 tons/y. The current recycling ratio of waste refrigerators was estimated as 88.53%. A total of 7,585 tons/y of waste computers were collected by the formal sector and 3,807 tons/y by the informal sector after discharge. Meanwhile, the current recycling ratio of waste computers was estimated as 77.43%. We found that it is possible to introduce 28 upcycling technologies in the case of refrigerators, and 15 technologies are available to promote upcycling in the case of computers. By refining the broad concept of upcycling and looking at the stages of material flow, our approach presents universally applicable directions for incorporating upcycling in resource recovery and recirculation plans.

Nowadays, flooding wast is serious problem to mankind and the endeavour for solving waste problem is performed in connection with environmental problem and natural resource problem. In Korea, there are a lot of movements related to reduction of waste, too. As the solution of these problems, recycling is recommanded and many kinds of recycling technique are devised. In America, military has been playing an important role in recycling area for a long time. This paper is the survey of several articles and working papers about America military's recycling research. We investigated the recycling of water, construction and demolition wastes etc. These research results are very important in real field of military. It is considered our military has to prepare this recycling problem and now it's the right time. All of these can be adapted to our military, commercial companies and civilians through some modification. We suggest that our military should cope with recycling problem more deliberately.

Currently, the global atmosphere around the world is altering at a very rapid pace. Among those changes, some are beneficial, but most of the changes are lead to destruction to our planet. The area of environmental science is a significant resource for learning more about these changes. Due to the urbanization, the human population is increasing, natural resources becoming very limited. To solve the limited resources issues, recycling is absolutely an alternative source for the new demands and limitations. Recycling education is very important to raise awareness among students and their communities about the need for recycling and what materials are recyclable locally. In this paper, we reported the role of sustainability science and technology and the impact of recycling research education in the middle schools, both in developing countries and Asian countries and also we included the brief data of global recycling of waste.
