  • 급속한 경제 발전과 인구증가, 일회용품의 증가 둥 사회구조가 대량생산, 대량소비 형태로 변화되면서 폐기물의 처리가 새로운 환경문제로 대두되었다. 도시 생활폐기물의 대부분이 매립 처리되고 있지만, 환경부에서는 매립처리의 비율을 줄이고 2001년까지 소각처리 비율을 25%로 늘릴 계획이다. 1997년에는 도시 생활 폐기물의 63.9%가 매립 처리되고 7.1%는 소각 처리되었으며, 29.0%가 재활용되었다(환경부, 1998). 한편 1995년부터는 쓰레기 종량제의 도입으로 도시쓰레기의 27%가 줄어들었고 재활용되는 쓰레기의 양이 35% 정도 늘어났다.

  • In this paper, we have implemented the living waste analysis system based on IoT and AI(Artificial Intelligence), and proposed effective waste process and management method. The Jeju location have the strong point to devise a stratagem and estimate waste quantization, rather than others. Especially, we can recognized the amount variation of waste to the residence people compare to the sightseer number, and the good example a specific waste duty. Thus this paper have developed the IoT device for interconnecting the existed CCTV camera, and use the AI algorithm to analysis the waste image. By using these decision of image analysis, we can inform their deal commend and a decided information to the map of the waste cars. In order to evaluate the performance of IoT, we have experimented the electromagnetic compatibility under a national official authorization KN-32, KN61000-4-2~6, and obtained the stable experimental results. In the further experimental results, we can applicable for an data structure for precise definition command by using the simulated several waste image with artificial intelligence algorithm.

  • This study investigated the spatial distribution of the marine debris in Jinudo in the Nakdong river estuary. Types of marine debris in Jinudo are analyzed through sampling around some portion of its sandbar shoreline. The present study and its main results are summarized as follow: 1) Monitoring system, for evaluating the volume of marine debris, was established in the coastal region of $50\;m\;{\times}\;50\;m\;(=0.002\;km^2)$ over the southern part of Jinudo. All the marine debris of conceivable form are collected and their amount was also estimated. 2) During the $1^{st}$ collection in May 2007, the total weight of the marine debris was 1,110 kg in this site, which means the density of marine debris around the shoreline is $444\;ton/km^2$. After one month later, the collected marine debris was 23.75 kg and so we have the average density of $9.5\;ton/km^2$. From these results, it is suggested that the marine debris of 316.67kg was being accumulated per day over unit area($1\;km^2$). 3) The most frequent marine debris collected during monitoring campaigns was wooden material amounting to 85.86% of the whole collection; the rest were fishing gears such as nets and buoys(5.13%), household waste(2.34%), glass(0.94%) and metals(0.27%).

  • As environmental sustainability becomes a key consideration in policy-making, more responsible consumption and utilization in daily life concern both health and quality of life. To address inequities in health in relation to environments, waste management has taken more progressive ways, and one of them is biomass-to-energy conversion that utilizes energy recovery from food waste. By extension, a food waste zero-emission system using fermentation and extinction technology gains much attention, so that this study is designed to examine residents' attitudes toward recycling food waste produced at home and toward food waste zero-emission system. Utilizing a survey questionnaire, this research collected data from 400 individual units of multifamily housing estates nationwide, and the data were analyzed using descriptive and inferential statistics. The findings indicate that food waste generated at home was highly water-contained and produced in the stage of food preparation before cooking while respondents viewed that food waste collection and treatment needed to be improved. It's noted that respondents strongly supported the use of food waste as a energy source and would have the use of the food waste zero-emission system built in kitchen sink. Regression analysis showed that educational attainment of housewives, cooking style, and planning food purchase were statistically significant factors in the attitude of the responded residents toward recycling food waste while none of the factors were in the attitude toward the food waste zero-emission system.

  • This study examined the environment and landscape aspects of rural villages, which are based on agriculture, to regenerate a disappearing rural village. The lifestyle and living conditions in this area were examined and the field survey of this area was carried out. The main negative factors at the rural landscape and living environment, such as rural households garbage, compost piles, and farming wastes, were found. An improvement plan of the landscape in this area was then determined. The disposal conditions according to the garbage types were analyzed through a survey with the residents directly. Through this survey, the current negative factors in landscape were checked and various improvement methods were assessed. Based on this, an institutional framework about landscape improvement of a village was developed, and a fundamental resource that can improve the environment of rural communities by this system is suggested.

  • 폐기물이란 쓰레기ㆍ연소재ㆍ오니ㆍ폐유ㆍ폐산ㆍ폐알칼리 등 사람의 생활이나 사업활동에 필요 없게 된 물질을 말하는 것으로, 쓰레기와는 엄밀한 의미로는 구분되지만 일반적으로는 버리는 것은 모두 폐기물이라고 볼 수 있다. 폐기물은 발생 주체에 따라 생활폐기물과 사업장폐기물로 구분되는데, 사업장폐기물은 사업장에서 발생되는 폐기물로 구성물질은 업종과 생산공정에 따라 다양하다.(중략)

  • 최근 인구증가와 더불어 도시화, 산업화 및 생활수준의 향상으로 인해 가정 및 사업장 등에서 배출되는 음식물쓰레기의 발생량이 급속하게 증가함으로써 쓰레기처리에 따른 비용절감과 효율적인 폐기물 처리방법들이 중요시되어지고 있다. 현재 우리 나라에서 쓰레기처리법으로 가장 많이 활용되고 있는 기술은 매립이다. 그러나 매립처리는 유기물이나 유해물질의 유출 및 악취발생 등 매립장 인근에 환경을 오염시키고 있다. (중략)

  • 우리나라는 1970 년대부터 급속한 경제발전과 더불어 생활수준의 향상에 따른 소비 성향의 변화 및 인구의 도시집중화현상 등으로 도시 쓰레기의 배출의 변화가 나타나서, 배출된 쓰레기의 양은 매년 증가되는 추세이다. 또한 배출된 쓰레기의 80% 이상을 단순 매립에 의존하는 처리방식이므로(환경부,1995), 유기성 폐기물이 혐기 소화되면서 다량의 가스와 침출수를 발생시켜 주변 지역의 자연 및 생활환경에 악영향을 미치며, 환경적, 사회적으로 큰 문제가 대두되고 있는 현실이다.(중략)
