  13. The objective of this project are to elucidate the thermal characteristics of plastics such as polyolefin, polyvinyl chloride, polyvinylidene chloride and their mixtures, and to develop the dechlorination technique by thermal treatment, prior to converting waste plastics to oils or other useful materials. Thermal properties of low and high density polyethylene(PE), polypropyrene(PP), polystyrene(PS) and polyvinylchloride(PVC) were analized in the range from 40oC to the decopmosition-vaporization state by a new apparatus for thermoanalysis, which was composed of thermogravimeter and conduction-type scanning calorimeter. Mixed plastics of PE,PP,PS and PVC, which contained PVC in the range from 4 to 40 wt%, were also analized. Performance test for dechlorination of mixed plastics were conducted by using an extruder which has two shafts rotating at opposite directions. Dechlorination ratio for mixtures of two or four kinds of plastics which contained PVC at 4 to 40 wt%were accomplished to 99.9 wt% under the conditions of decomposition temperature at 340oC ,and residence time of the plastics above 5.0 minutes. Measurements of thermal properties of dechlorination-treated plastics were done. Tests of oil recovery from treated plastics by thermo-catalytic decomposition were conducted and gasoline-like oils were obtained.

  13. The aim of this study is to investigate the influence of synthetic biodegradable polymers and their degraded products on the natural environment. Mechanism of biodegradation in various environments, survey of microbes, identification and their accumulation of degraded products, their acute toxicity to living things containg microbes and cells, fate of metals used for production of polymers are studied. From consideration of these results, the complete safety of novel synthetic biodegradable polymers and plastics would be verified.

  13. The aim of this study is to develope advanced techniques for analysis of toxic substances in polluted soils. From the point of view of preventing human health and ecosystem from being polluted by toxic substances from industry and anthropogenic pesticides, 25 chemical materials were designated as items requiring surveillance. The purpose of this project is to advance techniques for analysis of surveillance items solubilized from polluted soils, such as antimony, molybdenum, nickel, boron and so on. This year we present noble analytical techniques for characteristics and determination of antimony solubilized from the artificial synthesized and polluted soils.
