Recycling of coal combustion by-product(Ash) are becoming more important in the utilization business as a result of the increased use of NOx reduction technologies at coal-fired power plants. current disposal methods of these by-products create not only a loss of profit for the power industry, but also environmental concerns that breed negative public opinion. Since inherent characteristics make these by-product suitable for building materials, several types of artificial aggregates and construction bricks are manufactured and tested to verify the engineering properties.

It is the real circumstance in the country that not only the data and special books but also people who have an expert knowledge are short of the field of the study about plastic wastes, so that to build the Database carrying out gathering info of that is the present question obviously. The business on recycling plastic, for some reason or other, is one of the best ways as called bright prospect industry to prevent environmental pollution and obtain economical outcome by using limited resources. Plastic wastes with construction industry especially using Polymer may have a good effect on the environment and human beings and have a fine view to produce functional and Eco-friendly concrete as well. In this study, Chemical resistance and Water Absorption test in Polymer concrete using bentonite as a shrinkage control agent was made an experiment by comparing with influence on concrete strength and used to offer some valuable data about Polymer concrete.

The purpose of this study is to examine the actual condition of environment conscious logistics system which is essential to make material recycling economic society. Environment conscious logistics management which meant simply recycle is tend to promote material reduction, reuse and recycling. We have made case studies about advanced environment conscious logistics system. To examine korean companies' environment conscious logistics system, we made survey form which is consist of 81 questionnaires in Korea between 2003 and 2005. And we have analyzed the survey responses. As a result of this study, we propose the way of constructing environment conscious logistics system in Korea.

난지도 하수슬러지 매립지 내 슬러지의 적정 처리방안을 검토하기 위한 기초조사로서 슬러지의 매립량 및 성상을 조사하였다. 보링시험을 통하여 매립지의 깊이를 측정하였고 슬러지성상분석을 위한 시료를 채취하였다. 주요 분석내용은 슬러지의 화학적 특성, 중금속함량 그리고 용출시험이었다. 조사결과 슬러지 매립지는 평균 15m 깊이에 약 5만 평방미터 넓이로 총 매립량은 60만톤 정도로 추정되었다. 슬러지의 성상을 분석한 결과 일반적인 하수슬러지에 비하여 상당히 안정화된 슬러지임을 알 수 있었다. 또한 중금속 함량 시험에서 구리를 제외한 모든 항목에서 미국 캘리포니아주의 일반폐기물기준을 만족하였으며, 외국의 퇴비내 중금속허용기준치와 비교한 결과 대부분 기준치 이내이었다. 슬러지의 용출시험결과 난지도 하수슬러지매립장의 슬러지는 일반폐기물로 분류되었다.

태양전지용 웨이퍼 제조공정에 있어 Slurry의 가격 비중은 약 68% 정도로 매우 큰 비중을 차지하고 있기 때문에, 제조비용 절감측면과 Wafering 원가혁신 및 산업폐기물 처리비용 절감효과, 환경오염 방지를 위해 Slurry의 순환 사용은 필수적이다. 기존 Slurry를 재생하는 방식은 물리적인 원심분리(데칸터) 방식을 이용한 방법을 사용하고 있으나 미분(微粉)이 남아 있어 재생품질에 한계가 있고, 대부분 액체, 100% 오일과 분리되지 않은 상태로 재생된다. 이 상태를 건조시키는 경우도 순도가 많이 떨어진다. 본 논문에서는 원심분리(데칸터) 방식과 케미컬 방식을 함께 사용하여, 태양전지 Wafering 공정에서 필수적인 Slurry를 재생함에 있어, 원심분리에 의한 재생품질의 한계를 극복할 수 있는 재생기술을 개발하였고, Slurry 재생에 대한 Total Solution을 제공하여 성능을 향상시키고 재생 회수율을 높였다.

This study examines the effect of cosmetic certification marks on consumer behavior. The underlying objectives of this study are threefold. First, it explores whether the certification mark inserted into the cosmetic package-such as marks denoting quality assurances, ethical practices (specifically, pertaining to animal testing), and recycling packaging-affects consumer responses. Second, it investigates whether a higher number of certification marks leads to heightened positive consumer responses. Third, it analyzes the potential moderating effect of consumers' certification mark knowledge on the relationship between certification marks and consumer responses. In the pretest, certification marks with higher recognition were selected as stimuli, and a survey involving a total of 550 male and female consumers was conducted. The collected data were analyzed through ANOVA and post-hoc tests. The findings of this study confirm a significant difference in consumer responses to products based on the certification marks inserted in the cosmetic packaging. Compared to clusters without a certification mark, groups with two or more certifications (recycling certification + ethics certification, recycling certification + quality certification, recycling certification + ethics certification + quality certification) exhibit significant consumer responses. Second, more certification marks did not result in an increase in positive consumer responses. Third, a moderating effect of consumers' cosmetic certification knowledge on the certification mark-consumer response relationship was not found. The findings of this study have implications for developing product promotion strategies that leverage cosmetic certification marks as a marketing tool.

산업혁명 이후 인간의 대량생산과 과소비는 자원고갈, 환경오염, 폐기물발생 및 지구온난화 문제를 야기시키는데, 이는 물질제조와 사용 및 폐기를 반복하는 선형경제에서 기인 된 것이다. 선형경제의 문제점을 극복할 대안은 자원이용의 효율성향상을 통한 자원고갈문제 해결, 에너지효율 향상 및 대체에너지 개발에 의한 CO₂ 발생억제, 물질활용의 극대화 및 오염물질의 무해화, 제품의 재사용과 재활용 등을 통한 폐기물발생의 제로화를 기할 수 있는 유일한 방법인 순환경제로의 전환뿐이다. 순환경제는 사용 후 제품의 폐기보다 재생 및 재활용이 가능케하여 상호연결고리 안에서 반복사용함으로써, 생산 후 판매에만 그치지 않고 실질적인 가치와 편익이 대부분 다시 창출되는 사용 및 회수까지의 가치사슬을 확장하는 경제개념이다. 이를 이루기 위해서는 순환경제로 혁신적인 변환의 절실함을 깊이 인식하여, 지구생태계 보호 및 지속가능한 성장에 필요한 새로운 비즈니스모델을 제시한 다음 현실화화 시켜야 한다. 그리고 전술한 내용의 순환경제로의 전환은 필요성 인식, 성공적인 달성방안 및 방법확립, 다양한 비즈니스모델의 실현, 구체적인 우위기술 확보 및 정책적인 지원이 수반되어야 가능할 것이다.

Seaweed by-products have been dumped into the sea and induced marine pollution. However, they can be recycled as a valuable natural resources. Approximately 240,000 tons of sea mustard and kelp by-products were estimated to be producted during the last three years. The estimate corresponds 6.7% of the total production of marine aquaculture and 14.9% of the total production of seaweeds. When adding up the by-products from fish and mollusks, approximately 1,000,000 tons of fisheries by-products were thrown out into the sea every year. A three-step strategy is required for the industralization of fisheries by-products. The first step is the construction of the processing foundation of by-products, the second is its food industralization, and the third is its recycling as raw biomaterials. The stable supply of raw materials is the prerequisite for the industralization. Thus, it is necessary to construct the refuse logistics around chief production districts and to build the processing facility and frozen storage of by-products. Cooperation among private enterprises and government investment for research and development is required the second and third steps.
