  • 최근에 매립에 의한 도시 쓰레기 처리방법이 한계에 도달해감에 따라 이를 좀더 감량화하고 안 정적으로 처리할 수 있는 소각처리기술의 중요성이 더욱 부각되고 있다. 정부에서도 2001년까지 국내 생활쓰레기의 25%를 소각 처리하는 것을 목표로 투자 계획을 세워놓고 있으며 이를 달 성하기 위해서는 무엇보다도 소각기술 및 소각 플랜트 기술의 자립이 급선무이다. 현재 우리나 라의 소각로 기술은 초보적인 단계에 머물러 있으며, 그 동안 대부분의 소각로를 외국 기업으 로부터의 기술 도입을 통하여 건설하여 왔다. 이와 같은 방법은 기술적으로나 경제적으로 많은 불이익이 있으며 특히 소각로 설계 기술의 자립과 국산화라는 근본적인 목표 달성이 지연되는 문제가 있다. 이러한 기술상의 한계성을 극복하기 위해서는 무었보다도 선진 원본기술에 대한 심도있는 분석 연구와 정부 및 산.학.연간의 협조에 의한 연구 개발노력과 투자가 지속되어야 한다. 또한 소각로의 안전성과 신뢰성향상을 위한 꾸준한 기술개발이 이루어져야 하며 지역 주 민들에 대한 적극적인 홍보를 통하여 현재 문제가 되고 있는 소각로 기피현상을 조속히 타개해야 할 것이다.

  • 국내 A군에서 운영중인 한 쓰레기 매립지에서 배출되는 침출수와 주변 지하수를 채취하여 화학분석과 동위원소 분석을 실시하였다. 그리고 생활 쓰레기가 분해되는 과정에서 생성되는 가스들을 채집하여 동위원소 분석을 실시하였다. 유기물 분해로 생성된 이산화탄소는 일차적으로 침출수의 알칼리도를 높이고 이차적으로 일어나는 이산화탄소의 환원작용에 의하여 메탄가스가 형성되었다. 이러한 과정에서 침출수내의 용존무기탄소(DIC)의 탄소 동위원소 조성이 부화되었으며, 아울러 생성된 메탄과의 수소 동위원소 교환반응에 의하여 침출수의 수소 동위원소 조성이 크게 부화되는 특징이 관찰 되었다. 쓰레기장에서 발생되는 혼합가스에서 이산화탄소를 분리하여 탄소 동위원소 조성을 분석해 본 결과 새로운 매립지 보다 오래된 매립지에서 배출되는 이산화탄소의 탄소 동위원소 조성이 부화되는 특징이 관찰되었다.

  • Product design should reflect environment and experience of use in consideration of product's role as well as roles in life. In doing so, it is expected to realize interaction between product's role and users. Therefore, design of a recycling bin should also consider not only colors, shape, or materials but also process and experience of use. This study was conducted targeting public recycling bins in Beijing. As for the study method, first concept of a recycling bin was defined while specifying significance of recycling in Beijing City. Also, advanced research on recycling related policies that are currently being promoted was carried out. Second, current status of recycling in Beijing and problems of recycling bins were analyzed through on-campus survey. Lastly, users' psychological demand on a recycling bin was assessed and analyzed to suggest developmental direction of recycling bin design in the future.

  • Recently due to development of IT technology, ideas and technology that blend with environment have evolved. This technology can help people's living environment and in the future it is an essential component of the connected society. In this paper, we propose WiT(WiFI Trashcan) which takes advantage of the IT technology fusion and environmental factors at the same time to create a more pleasant environment. WiT provides a free WiFi when trash is disposed in the trash can. WiT detects whether a user disposes trash, determines the volume of the trash and provides free WiFi. To detect trash we use ultrasonic sensor and trash weight is measured by using weight sensor. Also by using Phython programming the measured sensor value is transmitted to Raspberry Pie and WiFi delivery time is determined. We used Arduino and Raspberry Pi to design and implement WiT.

  • Zero waste clean city was visualized by designing the environmental fundamental facilities such as automated waste collection and bio-energizing system of domestic waste, which was categorized into food and combustible waste from urban area. The biomass circulation position was applied to the domestic waste collection position combined with bio-energizing system in the zero waste clean city. Bio-energizing system consisted of bio-gasification, bio-fuel and bioenergy-circulation process. Food wastes were treated by bio-gasification with anaerobic digestion, and combustible wastes were made of bio-fuel with pyrolysis/drying. Biogas and bio-fuel was utilized into the electric generation or boiler heat in bioenergy-circulation process. The emission of carbon dioxide(CO2) and construction fee of the environmental fundamental facilities related with domestic waste was estimated in the existing city and zero waste clean city, assuming the amount of food waste 35 ton/day, combustible waste 20 ton/day from domestic area. Consequently, 2.7 times lower carbon dioxide emission and 15% construction fee of the environmental fundamental facilities related with domestic waste were obtained from the zero waste clean city by comparing with existing city.

  • This study was conducted to analysis citizen's attitude and style to the foodwaste from loth Sept. to 30th Sept. in 1996. The research was used questionare method and the analysis was used prequency analysis and cross table method by SPSS (scientific statistics). they answered that the most serious environment problem was waste problem and the best way to settle waste problem was to reduce waste production itself. And they answered that to settle environment problems, it was most important for us to change our life style. But It was not agreed between consciousness and action(execution). Because most of the food-related waste was among household waste, it's settlement was the most importment thing than any other. Nevertheless the seperation of waste was essential to effective incineration, the seperation process was not actually conducted and only a few housewife knew the difference of incinerable and non-incinerable waste. The recycling for the disused dry-cells and garbage is not completly. But we think that if the effective government's recycling counterplan for wastes, foodwaste or wasted dry cell, etc., is estabilished, rates of seperation and collection was increasing. Much usuage of onetime vinyl bag for shopping was become the one of the main cause in increasing the package waste, and so it was needed to use the longlife shopping basket.

  • This study aims to provide a program for the municipal solid waste collection and transportation management through data consolidation and field research of the materials about waste collection and transportation in a small city. The field research was conducted in the collection zone of the housing, apartment and business section within C city area. As a result, the main factor of collection and transportation plan required at the waste collection and transportation process and the central mean applying at the small city were calculated. The process that systemize the waste collection and transportation step and the expert system were constructed. In conclusion, the developed management system of the municipal solid waste collection and transportation can be wildly used by adding the data of other zone.
