We identified pyrolysis condition, effect of catalyzer and pyrolysis mechanism through contact decomposed method by adding Bentonite in waste plastic of hospital solid waste. The result from this study were summarized as the followings: 1. The optimum fuel oil were obtained when hospital wasted plastic (P.P) and Bentonite were mixed in the ratio of 30:1. 2. Maximum absorption wave of hospital wasted plastic (P.P) appeared at 2900cm$^{-1}$, 1480cm$^{-1}$, 1360cm$^{-1}$ and 1180 cm$^{-1}$ by FT-IR and the plastics were identified and confirmed. 3. Reaction temperature of hospital wasted plastic started at 360$\circ$C, proceed rapidly at 437.5$\circ$C and finished at 481$\circ$C. The residue was 0.729%. When bentonire was added started at 318$\circ$C, proceed rapidly at 399.5$\circ$C and finished at 449.3$\circ$C, the residue being 4.23%. 4. Pyrolysis products of hospital wasted plastic were about 90 kinds. The Main components were 2-Heptene-3-ethyl-4-trimethyl (27.4%), 1-Heptene-2-isobutyl-6-methyl (8.6%) and 1-Heptene decene (7.7%). There was little component difference at different temperature. This is the result from stability of decomposition product. 5. Pyrolysis efficiency increased by the addition Bentonire. 6. Some of the Environmental and Sanitary problems could be solved by the pyrolysis of hospital wasted plastic and the decomposed products were to be used as fuel oil.

The objective of this study is to investigate the generation rates, composition, propertion and lower heating values of each material in the municipal solid wastes(MSW) as well as the effect of landfill leachate on the environment in Taejon. The results are as follows: 1. The annual average generation rate of MSW in Taejon is approximately 1.7kg/c.d. 2. The weight percent of combustible matters is on average 80 and the lower heating value of MSW is measured to be more than 1,700 kcal/kg after removing the briquette component. 3. It is necessary for us to take a proper management system for leachate treatment in the landfill because it has many problems in the sewage and groundwater. 4. It is recommeded that MSW be treated by multiple methods such as the sanitary landfill, resources and recovery, composting and incineration.

This survey is related to the status of education for environmental managers, who are taking charge of pollution control untilities, and its analyses. This survey is also discussing the improvements of educational course for the trainees, who have already been educated in environmental background as well as its problems. The 45% of in-service trainees were those who had graduated more than a junior college. But under the 50% of them were those who had school careers of less than a high a high school, which means that the trainees have trouble in acquiring the professional knowledges on environmental educations such as the lectures and the practice educations. All over the country, 46 junior colleges, and 65 universities which have a environmental education program, have produced the graduates who major in the environment. Therefore, it is demanded that they should be properly treated. In this research work, it is shown that the 76% of environmental managers have no certificate of environmental study. It is thought that this has resulted from the released environmental law; the untilities of the first and second grade need a manager with a certificate related with environment, the third grade utilities only need a manager with a non-specified certificate related with environment or a manager with more than 3 years environmental practice careers, the fourth and fifth grade utilities do not need the certificate related to environment. In view of relation between environment pollutions and the management of environmental utilities, it is thought that present environmental laws should be improved to be strict. The fact that the differences in regions or utilities are not considered in the contents of texts, has reduced the efficiency of education. Therefore, it is needed that the experts and the in-service managers should take part in the development of the text. In this survey, the more than 20% of trainees have negative opinions about the result of this education, which means that overall the environmental practice education should be reconsidered. In the educational methodology, more than 50% of trainees have the opinion that they want spot speciations, the audio-visual educations and the practice. Therefore, it is demaned that the subjects, syllabus, and the allotment of time ect, should be reorganized for the more practical education.
