  • To provide successful treatment policy and to apply sources for establishing plan, municipal solid wastes quantity was investigated as physical and chemical characteristics from Sunchon city. Results are like following after checking out characteristics by seasons, type. The average specific weight of municipal solid wastes is $219kg/m^3$ for combustible wastes, $391kg/m^3$ for non-combustible. Food wastes of combustible wastes contained moisture of 38.1% as standard of moisture weight per real weight, 49.6% moisture is contained in non-combustible wastes except food wastes moisture. Moisture, volatile and ash are contented by 16.9%, 68.1% and 15.0% in combustible wastes except food wastes. That means combustible wastes are available a refuse incineration. The low calorific value of only combustible waste is 2,962kca1/kg that is good for refuse incineration.

  • Characteristics of household wastes production from fishing village in small island was investigated. Investigation was conducted in August and December to represent seasonal characteristics of summer and winter, respectively. Amount of household wastes production was 0.65 kg/capita·day and this is relatively low value compared with nationwide average. Food wastes, papers, vinyl and plastics are major part of combustible portion in household wastes. Composting is inappropriate method as a final disposal method in terms of C/N ratio calculated from elemental analysis. It is recommended that incineration can be appropriate way as a final disposal method of household wastes because low heating value of household wastes is equivalent to that of crude oil. The fraction of food wastes in household is considerably higher than the values obtained from other residential areas in nationwide. Thus, it is evaluated that household composting devices and vermicomposting facilities are necessary to reduce the amount of food wastes. It also can be evaluated that incineration is optimal method as disposal method of household wastes from fishing village except food wastes.

  • The purpose of this study is to suggest the design parameters, which are applied to the solid waste treatment and management systems in rural area. In order to drive out the parameters, the solid waste production and management systems in rural and urban areas had been surveyed and analyzed, respectively. The comparisons of the analyzed results are also introduced in the paper. The rural areas referred to the survey are grouped in accordance with the industrial activities in those areas. The conclusions of the study are as follows: 1) The solid waste volumes produced per day per capita in rural area are less than those of urban area. For example, the average volume produced in rural area in 1995 is 0.85kg, which is two thirds of those in Seoul area. 2) for the treatment, the country has depended mainly on landfill. On the other hand, the incineration treatment ratio has been in creasing in rural area. 3) The physical and chemical properties of the rural solid waste, according to the analysis, are similar to those of the urban areas, which means the living pattern in those two areas have a little difference.

  • The aim of this study is to find out major accumulation zones through field survey and moving route tracking trials on floating debris of Nakdong River. It also identified composition and accumulated amount of the floating debris by sample survey for accumulation zones. As a result, total 5 accumulation zones were selected from the midstream and downstream of the Nakdong River. There was a large amount of floating debris, including vegetation debris, in the accumulation zones. And two accumulation zones located in the downstream region, it is much more likely to flow into the ocean along river. From the sample survey on the major accumulation zones, more than $40{\ell}$ of floating debris were collected including vegetation and artificial debris. As a result of composition analysis for artificial debris, plastic(49%) and styrofoam(36%) were the majority in number. The present study is expected to help to plan an efficient pre-collecting activity and to reduce floating debris flowing into the ocean from the Nakdong River.

  • This study describes the national municipal solid waste stream of the United States based on data collected and published by EPA for 1960 through 2009. This paper characterizes the municipal solid waste stream of the nation as a whole, and can be useful for understanding the nationwide stream of America. Among the various materials contained in MSW, recycling status of the major materials of paper and paperboard, glass, metals, plastics, food scraps and yard trimmings are discussed somewhat more minutely.

  • 인간은 생활을 영유하는 과정에서 필연적으로 쓰레기를 배출하게 됩니다. 그러나 우리나라는 60년대까지는 주요산업이 1차 산업에 의존하고 있어 쓰레기 배출이 크게 문제되지 않았었습니다. 왜냐하면 그 당시에는 우리들의 일상 생활용품들이 대부분 인위적으로 개발한 새로운 물질이 아닌 자연에서 그대로 구했기 때문에 배출쓰레기를 일정장소에 적당히 처리하여도 자연의 물질순환계에 의하여 원상태로 돌아갔으며 또한 물질이 귀한 시절이어서 대부분 재사용, 재활용되어 특별히 버릴 것이 없었기 때문일 것입니다. 그러나 우리나라도 70년대 이후 경제발전에 따라 고도산업 사회에 접어들고 인구 도시 집중화 및 자연상태에서 좀처럼 분해되지 않는 새로운 화학물질 소재들이 다량 생산되고 생활수중 향상 등에 의하여 많은 양의 물질이 소모되면서 배출되는 쓰레기도 인간에 치명적인 위해를 줄 수 있는 성분이 함유됨은 물론 배출향도 엄청나게 증가하여 처리에 어려움을 겪게 되었습니다. 이에 우리도의 당면한 생활쓰레기 처리실태 및 문제점과 이에 대한 개선방안을 제시 논의해 보고자 합니다.

  • In this study the physico-chemical characteristics of solid waste and the thermagravimetric analysis of waste investigated. It was found that the combustible component, water and ash were 61%, 32%, 7% respectively. The amount of combustible component was much higher than those of others. It was shown that the total carbon and hydrogen of the waste 94% and the high heating value was 2897,883(Kcal/kg). The thermagravimetric analysis showed that the weight loss of wastes occurred as temperature increased, and the rate was higher in the temperature range of $300^{\circ}C$ to $500^{\circ}C$.

  • 우리의 일상생활에서 발생되는 생활쓰레기의 처리 문제가 심각한 사회문제로 대두되고 있다. 쓰레기의 일부는 재활용되지만 대부분의 쓰레기는 소각, 매립 등의 방법으로 처리되고 있다. 우리 나라는 협소한 국토사정과 매립과정에의 악취, 먼지, 침출수 등으로 인한 환경문제를 감안할 때 쓰레기의 처리를 매립처리에 의존하는 것은 바람직하지 않다. 따라서 우리 나라의 현실성을 고려할 때 소각처리의 확대는 필연적으로 볼 수 있다(1999, 고윤화) (중략)

  • In this study, the composition and physico-chemical characteristics of municipal solid waste (MWS) which was treated in national park area kyungnam-do landfill were investigated. It is necessary to measure the characteristics of MSW and sludge to build a waste treatment facility, the data-base and total managing of the landfill. This MSW was composed of 34.62% of food wastes, 36.05% of papers, 15.37% of plastics & vinyls, 2.28% of textiles, 3.33% of wood, 0.49% of rubber & leathers and others, respectively. Most of MSW are composed of food, paper and plastic waste and more than 90% was combustible waste. For three components, moisture is 29.84%, combustible component is 62.30% and ash is 7.86%. The chemical element has the high order of carbon, oxygen, hydrogen on the dry basis of wastes. Also, the low heating value of the MSW which is measured by calorimeter is calculated as 2377.8kcal/kg. low heating value of the sludge is calculated as 338.06kcal/kg.
