  13. The status of industrial wastes generation in the Korea industries was investigated. The data reported to the Ministry of Environment during 1989 to 1991 were analyzed especially for waste plastics, waste oils, and waste organics. Properties of the wastes samples were characterized by calorific value analysis, proximate analysis, ultimate analysis, halogen analysis, and trace elements analysis.

  13. In order to reduce the ecological impact of manufacturing, it is necessary to minimize the environmental burden of each part of the system. We have developed a new computerized simulation method for assessing the environmental impact of proposed new products and manufacturing processes. Inputs to the simulator include environmental loads, and product and facility information. The materials and energy which are input to and output from the system under analysis are measured in "Ecounits", an index which represents the total environmental burden of the resources used and system outputs. The output from the simulator allows calculation of the predicted increment in ecounits caused by operation of the system. During tests of the simulator, the environmental impact of a hypothetical factory producing mechanical components was predicted, and the simulation method was shown to provide realistic and useful data.

  13. The ecologically conscious product depends mainly on how much consideration is given toenvironmental issues in the design phase. In this project, design strategy for materials selection and structure decision for aiming at resource recycling, is investigated, and a developing prototype design support system which is based on such strategy is introduced. In this system which is based on commercially available CAD system and database, material candidates are selected with solving trade-off relations among ecological, functional, andeconomical criteria tohelp a designer's choice. Also, essential parts which should be dismantled for resource recy-cling are pointed out, and dismantling information such as manual operation time is estimated from CAD data and some attribute data, to help a designer decide basic structure of product. Selected joining method and products performance such asproducts strength should be examined in the future work.

  13. The goal of this research is to develop techniques for hydrocracking flame-resistant macromolecular organic materials. It is vitally necessary to explore cheap hydrogen donors instead of gaseous hydrogen and active catalysts promoting hydrogen transfer from hydrogen-donor solvent systems to flame-resistant macromolecular organic materials. It has been revealed that organic fractions of coal liquefaction residues (CLR) obtained in the NEDOL Process act as effective hydrogen-donors and hydrogen-shuttlers. Binary systems of tetralin and CLR are expected to be feasible hydrogen-donor solvent systems. Ni and some active carbons with high O/C ratios have been shown to be promising catalysts transferring solvent hydrogens to flame-resistant macromolecular organic materials. Carbon materials can be expected as robust catalysts against deactivation in this research, and their exploration is still in progress.

  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. This study aims at developing in situ water treatment systems employing recycled local materials for use in rivers and lakes . Waste ceramic materials have been considered potentially useful as recycling materials for preparation of porous carriers supporting microbial adhesion and growth. Effective microorganisms, including aerobes and anaerobes, used in the purification of water supplies are immobilized in the surface-modified porous ceramics by immersing the ceramics into a seed culture broth. Design and synthesis methods for porous ceramics carriers with enhanced microbial functions from recyclable waste materials are investigated.

  13. Recently, pollution of valuable water due to daily waste water or industrial waste water has been spreading on the earthwide scale to become a world wide problem. The treatment of waste water using TiO2 photocatalyst is able to decompose toxic and bioresistant organic pollutants readily. In such water treatment studies, TiO2 powders in general have been utilized as photocatalyst. TiO2 film photocatalysts have several advantages:1)it is easy to treat,
    2)filtration is not necessary to separate catalysts from treated water, 3)continuous treatment of waste water is possible. In this study, the development of highly active TiO2 film photocatalysts prepared by sol-gel method, the research on the destruction of bioresistant organic pollutants and the development of water treatment system using the TiO2 film photocatalysts are being performed.

  13. Prawns are cultivated in an enormous amount in Southeast Asia including Thailand. Prawn shell waste is discarded and therefore causesan environmental problem. The shells contain chitin, a polysaccharide, which can be converted into various highly valuable materials. This project is designed to prepare chitin, chitosan and their derivatives from prawn shells and to explore their potential in practical use such as a flocculant, heavy metal adsorbent and paper additive.
