Using materials recovered from the waste stream instead of virgin resources as a raw material in manufacturing has great environmental and economic benefits. However, there is lack of public interest in needs for integrated waste management and its relevant facilities, because of NIMBY syndrome, This article has proposed a system dynamics model for the study of the potential and systemic consequences of resource circulation management system(RCMS) policy for a Sudokwon landfill site in Korea. The results of the study indicate that the effects of RCMS are seen continuously to increase in term with both the community welfare level and the resource and energy level. Moreover the effects of RCMS appear sharply in the first half of the simulation period.

Along with the expansion of industrial activities, the quantity of industrial waste sludge is increasing, and the treatment/disposal of wastes is a social problem regarding the preservation of the environment. In particular, recycling the sludge as a raw material is actively required considering the situation of Korea, which is poor in natural resources and energy. Lime is a necessity for treatment of waste sludge, which often can be made recyclable by lime treatment. In this thesis, a brief description has been given of my views on the ordinary treatment of waste sludge and the effective use of inorganic industrial waste sludge focusing on lime.

This study is conducted to examine the ways to reduce the garbage amount by effective recycling food wastes in the cooking. The data is collected from 864 housewives who live in Seoul/Sungnam/Choongju by using questionnaires from 24 November 1997 to 5 January 1998. The results are as follows; The level of their needs of reusing food wastes in the cooking is high but the level of their participation and its satisfaction to reuse housewives is low. Especially they take part in reusing the garbage in pre-treatment less than edibile plate wastes. These factors result from lacking of their consciousness and knowledge of methods to reuse food wastes. Therefore it is said that consumer should make an effort themselves to participate in reusing food waste researcher should search the way to efficiently reuse the food waste and government should found the policy to provide information and education program for reusing food waste. The more seriously they perceive food waste reuse the mo e they want the way to accelerate food waste reuse by consumer researcher and government.

A weight-rate disposal system for food waste has been implemented in all over the country. The food waste disposal system is a system paying service charge according to the volume of food waste, which means the more we produce waste, the more we have to pay as much.Since this policy was introduced, each of apartment, villa, etc and other buildings must install the food waste disposal system. We can say that there are strong points in this paper for us to install a weight monitor on the channel of the floor each, accumulate the fares automatically and collect the fares at the end of every month.

2005년 중 저준위 방사성폐기물처분시설의 부지선정 과정은 목표를 달성했다는 측면에서 성공 사례로 평가할 수 있다. 그러나 과정에서 나타난 한계점들은 여전히 풀어야 할 숙제로 남아 있다. 이 정책의 성공과 한계에 대한 영향 인자와 이들 상호간의 관계를 분석함으로써 향후 관련 정책 수립 및 추진에 효과적인 틀을 제공할 수 있을 것으로 예상된다. 방사성폐기물처분시설 정책의 정성적인 요인들은 변수로 설정하여 방사성폐기물처분시설 모델을 수립하였으며 이 모델을 계산하기 위하여 통합적 분석 툴인 시스템다이내믹스를 활용하였다. 시스템다이내믹스 분석 결과를 보면 정책주체의 투명성, 지역 지원 수준, 홍보를 조절 가능한 요인으로 설정하였을 때, 찬성 논리와 반대 논리 사이에 직간접적으로 영향을 미치고 중간에 신뢰가 매우 중요한 역할을 하고 있음을 가시적으로 나타낼 수 있었다. 신뢰는 제시된 여러 인자들에 영향을 미치거나 피드백되어 의견이 결정의 방향성을 전환할 있는 정책지렛대라 할 수 있다.

This research considers a system containing a manufacturing firm who generates waste material during manufacturing process, and a disposal firm who collects and disposes the waste material. Identification of the optimal number of pick ups and the amount of waste to be disposed at certain period of time in terms of cost minimization is studied. Two types of waste accumulation rates, constant and linearly increasing, are discussed and mathematical models are developed. It can be shown that the results for these two different types of waste accumulation differ in a wide range because of the difference in the way of how waste is accumulated, which disturbs the storage cost. An integrated model is also developed and discussed in which both the manufacturing firm and the disposal firm benefit from the coordination between the two parties. It is shown that the optimal policy adopted by the integrated approach can provide a strong and consistent cost-minimizing effect for both the manufacturing firm and the disposal firm over the existing approach. Finally, all the models are verified by a numerical example and the results are compared.

This study uses text mining compares and contrasts consumers' social media discourses on dietary related zero-waste movement before and after COVID-19. The results indicate that the amount of buzz on social networks for the zero- waste movement has been increasing after COVID-19. Additionally, the results of frequency analysis and topic modeling revealed that subjects associated with zero-waste movement were more diversified after COVID-19. Although the results of a sentiment analysis and word cloud visualization confirmed that consumers' positive responses toward the zero-waste have been increasing, they also revealed a need to educate and encourage those who are still not aware of the need for zero-waste. Finally, consumers mentioned only a small number of companies participating in zero-waste movement on SNS, indicating that the level of active involvement by such companies is much lower than that of consumers. Theoretical and educational implications as well as those for government policy-making are considered.
