The anaerobic fermentational condition of 15 to 20 of C/N was adjustable for the experimental of waste, which came from the agriculture fisheries freight station. A breeding sludge became to anaerobic biological steady state two days after the injection which defined the loading period of an organic matter A biodisintegrational experiment showed that the solid material created 150 to 200ml of methane gas from the first day through the fifteenth day. And the liquefied material created 100 to 200 ml of accumulated mathane gas through the twentieth day. The experiment of on biochemical mathane potential showed that the solid material became stabilized containing 60% over of methane gas after 10 to 20 days after the experiment started. The liquefied material did not stabilized until 10 days containing 39 to 58% of mathane gas. This experiment showed that the mathane gas conversion by anaerobic counteraction seemed to be potential as a matter of agriculture fisheries wastes disposal.

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 result of the study and analysis on the formation and the mutual relation of environmental consciousness followed by residential forms are as bellows; The ratios of the subjects of this study for each gender are ; 68.1% of male and 31.9% of female. And the group of aged thirty to thirty-nine occupied 33.2% as the majority. Each residential group comes up to 65.0% of using washstand when they wash their faces and hands. While being in the kitchen, 55% of individual housing residents and 61.8% of tenement housing residents are using basins, and the ratios are occupied very highly. 52.5% of discharged water which is accrued from the rice-wash is used for flower gardens and dish washing, and the ratio of direct discharging the water comes up to a very high ratio regardless the residential forms. 33.2% of the subjects of this study do car washes, and the residents living in the tenement housings and apartments do more car washes than the residents living in the individual housings do. 51% of the subjects or this study do warm-ups of the automobiles and apartment residents highly grasp the warm-up ratio while individual housing residents showed lesser warm-ups. 57.2% of the subjects of this say, they do not know well about the greenhouse gas and the tenement residents occupied high ratio. 10% of individual housing residents do not recycle garbage and this group grasps the highest rate. 57.6% of the entire subjects of this study do separate discharge of the rubbish but 61.8% of the individual residents do not separate discharge.
