  • This study aims to analyze region-specific trends in changing greenhouse gas emissions in incineration plants of local government where waste heat generated during incineration are reused for the recent five years (2009 to 2013). The greenhouse gas generated from the incineration plants is largely $CO_2$ with a small amount of $CH_4$ and $N_2O$. Most of the incineration plants operated by local government produce steam with waste heat generated from incineration to produce electricity or reuse it for hot water/heating and resident convenience. And steam in some industrial complexes is supplied to companies who require it for obtaining resources for local government or incineration plants. All incineration plants, research targets of this study, are using LNG or diesel fuel as auxiliary fuel for incinerating wastes and some of the facilities are using LFG(Landfill Gas). The calculation of greenhouse gas generated during waste incineration was according to the Local Government's Greenhouse Emissions Calculation Guideline. As a result of calculation, the total amount of greenhouse gas released from all incineration plants for five years was about $3,174,000tCO_2eq$. To look at it by year, the biggest amount was about $877,000tCO_2eq$ in 2013. To look at it by region, Gyeonggido showed the biggest amount (about $163,000tCO_2eq$ annually) and the greenhouse gas emissions per capita was the highest in Ulsan Metropolitan City(about $154kCO_2eq$ annually). As a result of greenhouse gas emissions calculation, some incineration plants showed more emissions by heat recovery than by incineration, which rather reduced the total amount of greenhouse gas emissions. For more accurate calculation of greenhouse gas emissions in the future, input data management system needs to be improved.

  • 우리나라의 대형 생활폐기물소각시설의 건설시기를 보면 상당수가 1980년대 후반인 것을 알 수 있다. 대부분의 시설들은 이 시기에 설계되었으며 그 후에 건설된 소각로 역시 변경이나 조정 없이 시설해온 것으로 조사되고 있다. 그러나 소각로에 반입되는 폐기물의 성상은 정부의 폐기물수거 정책에 의해 급격히 변화하고 있다. 이는 생활폐기물의 발열량변화를 조사해 봄으로도 쉽게 알 수 있다. 그 결과 많은 소각시설에서 과열에 의해 내화물과 화격자가 손상되고 있다. 한편 보일러 전열면에 클링커가 생성되어 열전달에 방해를 줌으로 이용열량이 줄어들 뿐만 아니라 연소실의 온도가 상승되는 등 원하지 않는 현상이 연속되고 있다. 이를 개선하기 위해 폐기물저장고에 물을 뿌리거나, 분리수거해 온 음식물류 폐기물을 다시금 혼합하여 혼소하거나 연소실에 물을 분사하는 방법을 동원하고 있다. 이러한 방법은 근본적인 해결책이 되지 않으며, 설계부터 다시 하여 새로 시설하는 것 또한 비용적인 측면에서 효과적이지 못하다. 따라서 본 연구를 통해 위와 같은 문제를 원천적으로 해결 하기위한 방법을 도출해 보았다.

  • The purpose of this study is providing basic data to control the air pollutants from solid waste incinerator. Incinerating the waste wood, the electrostatic precipitator had the best collection efficiency. The leather incineration had the same collection efficiency as synthetic resin incineration. And the coarse particle collection efficiency was high. As you know in correlation of leather incineration. pollutants produced a from incinerator are mostly fine particles. If the scrubber used only in the process produced a lot of fine particles. It is adequate to use the above control devices, together with high efficiency collector like bag-filter. To select the adequate control devices, it is required to investigate the size distribution before establishing control devices.

  • A scrapped fiber-reinforced plastic(FRP) fishing vessel causes many environmental problems, because technology development for recycling FRP vessel has not been adequately addressed. FRP is a main material for constructing a small coastal fishing vessel that is an object of reduction policy. Therefore, the FRP wastes derived a scrapped fishing vessel are increasing. In this study, I investigated an effective disposal process for FRP through the analysis of the actual conditions of scrapped FRP fishing vessel. The treatment processes of scrapped FRP fishing vessel are carried out with oil-removing, dismantling, intermediated processing(crushing), and then reclaiming follows burning in the final processing in Korea. However, in Japan, several recycling methods have been developed, for example, the incineration including thermal recovery, the use of cement-reclamation, and the use of asphalt concrete aggregate, because the method of reclaiming after incinerating which is generally used in Korea produces a toxic by-product such as dioxin.

  • Main disposal technology for industrial wasites in Korea has been landfilling, however, this is encountering serious problems such as the lack of landfill sites and objections of residents. Incineration, therefore, has become a final solution for this dilema. Various kinds of air pollutants generation are possible because of the variety of types and compositions of wastes generated in industry. In this paper, air pollutants produced while incinerating hazardous industrial wastes are discussed and some control technologies are surveryed with the purpose of optimal design of incinerators and emission reduction. From this initial stage of incinerator utilization, low-emission type should be developed and applied and intensive research on pollutant generation due to waste incineration and advanced control technologies should be also performed.

  • In this paper, the life cycle assessment(LCA) methodology is applied to Personal Computer's basic materials in order to analyze the impact to the environment. LCA data collection is carried out taking into account on main materials of PC's parts and component. And the impact assessment is the environmental burden on three factor into air emission(CO2, SOx, NOx), five factor into water emission(BOD, COD, SS, N, P), and three factor on transported substance(cl, NH4, SO4). According to the result, the environmental burden of PC's basic materials was proved to be used total energy 6,285Mj and emitted CO2 259.8kg, SOx 3,571g, NOx 330g, COD 1,328g, P 246g, N 2,434g. And this paper was presented the problems of its disposition-incinerating, landfill, and recycling.

  • In case of domestic pyrolysis dry distillation gassification technology, it stays at the stage of its early introduction and development. Moreover, the companies possessed of this technology are limited to Japan and some countries in Europe, and domestic operative performance of this system is nominal, so there exist a lot of difficulties in securing its basic data. In addition, considering its operation and management, there happens a corrosion of metals by the production of corrosive gases in time of combustion of waste, and there arise a problem of occurrence of low temperature corrosion on exterior casing or gas ducts of a combustion chamber due to the high temperature corrosion around the burner of an incinerator, lowering the durability of an incinerator. Therefore, this study looked at the problems arising in time of incineration by understanding the characteristics of the pyrolysis dry distillation gassification incinerating facility, and did research on the improvement plan for durability of an incinerator for more economic, efficient waste incineration.
