This report summarizes the result on selecting sites for large-caliber production wells, and landscape characteristic evaluation for simulation, based on the landscape survey on C candidate site for geothermal development. Field survey was made on landscape, plants and animals in the Kirishima Eboshidake area. It was clarified that this area has diverse flora including some rare species such as rein orchid and monkshood which are listed as endangered species. In addition, not a few epiphytes were identified. The zoological survey result showed that planted forests of evergreen coniferous trees which cover a wide range of the surveyed area, and peripheral grassland, scrub and natural forests provide good habitats for mammals such as sika deer and wild boars. On the other hand, no animal species in need of special protection were found. Geologically some traces of landslide occurrence in the past were detected in the northern part of the surveyed area relatively. As the survey result, some promising sites suitable for geothermal development were selected, which are judged to have a relatively small impact on natural environment and landscape. (NEDO)

International Panel on Climate Change (IPCC) published the 1st assessment report in 1990 and the 2nd report in 1995 since its establishment in 1988, and is promoting the 3rd research and analysis. Among them, this report describes the study on technology transfer for efficient energy consumption. For stabilizing greenhouse effect gas concentrations in the air, strong control of such gas emission is indispensable, and a role of technology is important for the control. For overcoming some weak points for climate change, practical use of applicable technologies is necessary over a certain period of time, and technology transfer is essential in each country and all over the world. For promotion of such approach, the analysis and evaluation for technology transfer and diffusion are useful in addition to reports on technology itself. Based on such understanding, IPCC has promoted preparation of the special report on methodological and technological issues of technology transfer since 1997. Its approval at the IPCC general meeting is expected in late 1999 or early 2000. Some chapters related to efficient energy consumption are presented. (NEDO)

In an effort to help preserve the global environment, International Center for Environmental Technology Transfer (ICETT) contributes to the solution of global environmental problems by promoting research exchanges with developing countries. As a part of this effort, ICETT hosted an environmental development researcher who visited Japan from the Institute of Environmental Research of Chulalongkorn University in Bangkok, Thailand. The invitation was extended at the request of NEDO. During the period of this investigation between September 16 and December 14, 1997, a photocatalyst was prepared and its performance was evaluated under the theme ``Application of photocatalysis to purification of atmospheric environment.`` At the same time, roadside test spots were inspected to study the practical application of optical photocatalysis. The visiting researcher also visited the National Institute for Resources and Environment to discuss with the staff of institute. This helped to deepen understandings of the state of air pollution problems confronting Japan, Europe, and North America, as well as issues related to the technologies that have been developed to solve these problems. The visiting researcher toured the RITE and examined Japan`s progress in the development of environmental control technology through joint research involving government, industry, and academia. At ICETT, the visiting researcher received training in Japan`s approaches to environmental problems in developing countries

Global environment handling technologies were investigated and put into order. Universities often make research and development on themes that can be handled at laboratory levels or by simulations. Development at a practical application level is few. Technological seeds may include manufacture of hydrogen by water and steam decomposition using solar energy, and new synthesizing reactions utilizing solar energy. Included may also be urban type wind power generation, superconductive energy storage systems, biomass utilization, and natural energy utilization. Furthermore, CO2 recovery and utilization by liquefaction, alkaline metal heat power generation, and pulse power technologies can also be found. Studies on applying advanced technologies to environmental measures include composite materials, membrane separation, photo-catalysts, optical elements, porous bodies, functional polymers, bio-reactors, electron beams, and aeration. Private corporations are working noticeably on prevention of fluorocarbon and dioxin emission, PCB treatment and waste water treatment technologies, catalyst application technologies, recycling technologies, and incineration ash treatment and utilization technologies.

The paper arranged the present situation and the problems of environmental cooperation for developing countries, and studied based thereon how to cooperate in environmental protection for developing countries in the future. At the same time, it arranged the problems/subjects posed when environment-related companies in Japan try to transfer environmental technology to developing countries, for the purpose of using them as data in studying possibility of reviewing the environmental cooperation presently conducted. A view on environmental cooperation is that as security of mankind, it is necessary to help developing countries in technology/knowledge/fund. However, a trial calculation indicated that the initial investment of 11.1 trillion yen is needed only for desulfurization and water treatment in China and ASEAN countries. Such a huge amount of money cannot be paid at all even by developed countries. As the support of environmental protection measures, the one also including energy and resource is needed. Further, the support of environmental protection measures should be the one that has the exhibition effect and influential effect, promotes efforts of developing countries' own, and pushes independent environmental measures forward. From this point of view, a study was made on what the details of the environmental cooperation should be like. (NEDO)

In order to serve for measures against global problems taken by Japan, joint research was carried out with overseas research organizations. The research project selected ten themes considering urgency, internationality and economic proliferation effect in areas to serve for solution of global environment problems. These themes include removal or emission control of greenhouse effect gases, measures against atmospheric environment problems such as acid rains and ozone layer destruction, prevention of ocean contamination, development and effective utilization of energies and resources. When the feedback of these themes to the NEDO projects is considered, the research achievements in relation with development of the acid rain monitoring system in particular support indirectly development of carbon dioxide fixation technologies. The research achievements in developing an environmentally friendly biomass energy manufacturing process and environmental effect evaluation thereon contribute as an effective process to carbon dioxide reduction using biomass as raw materials. The achievements in research of nonlinear interfacial properties and mixed phase turbulence of low-purity carbon dioxide bubbles contribute to a project related to storage of carbon dioxide in oceans.

Described herein are the FY 2000 results of the research study on environmental information network formation. The Internet is experiencing an explosive increase in volume of information distributed therethrough. This is accompanied by increased problems related to information searches, information exchange security and information-reliability guarantees. First in demand are excellent portal sites, and second are sites that can be relied on to responsibly provide information. Cooperation with the real world off the Net is of particular importance, because the operating organizations, e.g., sites, will lose their raison deter, unless they clarify their unique abilities and characteristics under the tendencies towards broadened bands and ubiquity. The public sector, on the other hand, is highly reliable, accumulates a large volume of information, and has high network capacity. It has various functions, e.g., supporting the activities pertaining to ISO standards, and promoting the activities, e.g., those for educational programs, interdisciplinary exchanges by researchers, and matching of various organizations. The international cooperation for environmental information needs construction and operation of the networks, and construction of the infrastructures in the developing countries. If information becomes more ubiquitous, a chaotic sea of information will result. NEDO is strongly obliged to serve as the beacon, because it has established a huge volume of environment-related technologies, information, and networks. (NEDO)

Processes that contain latent environmental problems are the massive generation of wastes (inorganic salt, acid catalyst, base catalyst, and huge quantities of wastewater), handling of dangerous substances (use of hydrogen fluoride, use of phosgene, and use of substances whose discharge is legally controlled), processes which consume much energy (circulation of quantities of raw materials, use of quantities of solvents, separation of products with difficulties, use of high pressure, and multiple stage reaction), and processes which are expected to use resources now remaining unexploited. As an element technology for the solution of problems, there is the development of a solid redox catalyst for liquid phase oxidation. As compared with a liquid phase homogeneous catalyst, it discharges less inorganic wastes, facilitates the separation, recovery, and treatment of inorganic salts, corrodes structural materials less, and is thermally stable. An alkane partial oxidation catalyst when developed will achieve more energy conservation than an alkene oxidation catalyst. In relation to acid/base reaction, the zeolite catalyst will be improved and ultrastrong acids and ultrastrong bases will be developed, and these will reduce wastes, mitigate corrosion, and facilitate product separation. The development of a process is also expected which will avoid the use of toxic phosgene. (NEDO)

This paper describes a survey on an environment technology transfer information network. Based on the achievements obtained by the surveys in fiscal 1995 and 1996, the ICETT has participated as one organization constituting the APEC environment technology exchange virtual center, and begun providing information since April 1997. As the environment technology information, those items actually employed by factories and operation sites in Japan are put into a data base, and into a home page including training information centering around those contained in the data base, and examples of works done by local governments for prevention of pollution. Furthermore in fiscal 1997, a simulation software for a model process has been developed. Fiscal 1998 strengthened the data base for environment preservation technology information, investigated environment preserving model companies and summarized them including even their management aspect. Investigations were carried out in developing countries on application of cleaner technologies. Gaps far exceeding anticipation exist in every field between these developing countries and Japan. Environment protection measures applied and succeeded in the developing countries as the means to narrow the gaps were collected, and compiled as the specific examples. (NEDO)

Described herein are results of the natural environment surveys, carried out in the Shitanotai Region in Yuzawa City, Akita Pref., where Geothermal Development Promotion Survey C is scheduled. On-the-spot surveys, conducted from June to November, covered 3 items of landscape, vegetation and animals. The Shimonotai Region has a number of ponds and swamps, some of which are used as fields for Brasenia shreberi, and wet shield plant communities in places reflecting these environments. The zoological survey results show that moderate to dry deciduous forests of Japanese beeches (Fagus crenata) and Mongolian oaks (Quercus mongolica var. grossesserrata) in this region provide sound habitats for large mammalian wild animals, e.g., moon bears (Selenarctos thibetanus). For birds, there are some areas extracted indicating high possibility of being inhabited by honey buzzards (Pernis ptilorhyncus), which are listed as a near threatened species by the Environment Agency. Geologically, traces of landslide occurrence in the past have been detected widely, indicating need for more detailed investigation for land stability. These surveys have extracted several areas whose natural environments and landscapes are damaged relatively little by geothermal development. (NEDO)

By research groups having been sent, the integrated evaluation was made of the projects on the research cooperation with Indonesia in the development of environmental measurement use laser radar and the research cooperation with China in the mining waste water treatment technology using biology. As to the research cooperation with Indonesia, the purpose/target proposed were almost achieved, and all were favorably carried out. Especially, after finishing the project, the design/manufacture of an on-vehicle type Mie-scattering laser radar were made using the acquired laser technology. And, it was reported that an observation study of the state of air pollution in Bandung city was made using the laser radar. It can be said that generally the research cooperation with China was smoothly proceeded with. However, the Wushan mine is small in scale of management, and therefore, there might have been some points to be reviewed in selection of the mine for research. The pilot plant installed at the Wushan mine is not now operated. If the mine has strong management force, the effective use of the pilot plant after finishing the project might have been studied.

The water environmental criteria in China consist of the sea water criteria, surface water criteria, fishery water criteria, agricultural water criteria, and scenery and recreational water criteria. This paper describes the problems thereof and the future assignments. The `sea water criteria` among other classifications of the water environmental criteria are under discussions for amendment that plan to increase the kinds of water from three in the conventional criteria to four kinds. Generation of harmful chemical substances has kept on decreasing since the 1980`s. However, as can be seen in part of the river water monitoring data, concentrations of pollutants show a trend of increase since 1994. This is caused by waste waters discharged from small-size chemical factories and hide tanning factories. Adequate regulations are applied to these `local enterprises`. Organic compound substances regulated under the waste water criteria are only seven kinds. As the kinds and amount of harmful chemical substances are anticipated to increase in the future, regulations that can deal with the new situation are required. Improvements are sought in the system of `discharge and contamination fee` imposed on industrial waste waters. Preparing the criteria for a total quantity regulation is an important assignment to be discussed as the forthcoming problem. 5 refs., 4 tabs.

In order to investigate useful protective medicines for the relief of skin injury induced by irradiation, 60 methanol extracts of Chinese traditional medicines were used in the test of protective potency on skin injury. ICR male mice at 6 weeks of age were whole-body irradiated with 1100R by using a soft X-ray generator (30 kVp, 10 mA, 190 R/min). Each methanol extract of these medicines was injected intraperitoneally into mice before or after irradiation. The degrees of skin injury were determined by a score system of skin reaction within the observation period from 21st to 40th day after irradiation. Protective potency of each medicine on skin injury was calculated from the maximum mean scores of administrated group and un-administrated group. As a result of these studies, the protective potency was detected in Unsei-in, Kumibinro-to, Keisi-syakuyaku-chimo-to, Keigai-rengyo-to, Gosyuyu-to, Koso-san, Saiko-seikan-to, Syo-kankyo-to, Syo-saiko-to, Syoma-kakkon-to, Sen-kan-meimoku-to, Zokumei-to, Sokei-kakketu-to, Bokuryo-in, Mao-to and Rikkunsi-to by intraperitoneal injection before irradiation. Of these effective medicines, only Unsei-in and Mao-to are shown to have a significant protective effect by intraperitoneal injection after irradiation. (author)

Proposals have been made for the establishment of a network (ETERNET-APR) linking those involved in the research and development of environmental technology in the Asia-Pacific region in order to limit the environmental impact of industrial activity. By pursuing active exchanges of information and personnel, researchers in environmental technology in the Asia-Pacific region have been making serious efforts to establish such a network. This fiscal year, the Internet Web site of the ETERNET-APR has been created using the data collected to date. This database includes information on some 350 researchers and 200 research projects from seven countries. The first international symposium was successfully held at Environmental Research Institute of Chulalongkorn University in Thailand (ERIC), hosting 200 environmental researchers from 10 countries in the Asia-Pacific region. Tripartite sister laboratories ties among the National Institute for Resources and Environment (NIRE) and three Korean laboratories were forged. The sister laboratory project between ICETT and ERIC is also proving effective. These successes prove that intraregional joint research, the objective of ETERNET-APR, has begun to take shape in this year

Outlines of various energy supply/demand analytical models are surveyed. With environmental problems gathering importance, a number of models are being introduced in which energy supply/demand structures, long-term climate changes, and impacts of policy options on social economy are linked to each other. Some socioeconomic impact models cover a single country and others the whole world. They are various in type, ranging from dynamic optimization models to static balance models. Twenty-four models are chosen, and grouped into two types respectively covering Japan and the whole world from a geographical viewpoint and into three groups in view of their structures. Under an optimization model, such optimization is accomplished as economic growth maximization and energy cost minimization and so forth under given energy supply restrictions. Under a general balance type econometric model, an adjustment process in which capital and labor and production are coordinated across multiple departments is expressly stated. Under a partial balance type econometric model, a demand function for goods is given and optimum behavior such as consumption maximization is indirectly described. (NEDO)

Taking the area of the clean coal technology (CCT) effective for energy conservation and environment preservation as the object, a feasibility survey has been performed on executing a model project in India. About 70% of the total power generation capacity in India depends upon coals existing in abundance inside the country. Since the local coals are high in ash, low in sulfur, and low in calorie, the environmental problem related to thermal power plants is the disposition of fly ash. The Central Electricity Authority of India expects solving this problem by CCT introduction. It also expects increase in combustion efficiency by using ultra-critical boilers. The Indian cement industry often uses in-house electric power generation facilities because of high electric power cost, wherein the produced coal ash is used as a cement raw material. The matter of the strongest interest is the introduction of a high-efficiency combustion system that depends on low-grade coals. Among the CCTs, strong interest was shown in the fluidized bed cement kiln and the circulating fluidized bed boiler. The iron and steel industry has expectations toward effective coal washing technologies and coke manufacturing technologies. (NEDO)

This paper reports the surveys in fiscal 1999 on research and development of the environment harmonizing catalyst technology. The discussion subjects taken up included suppression of discharge of carbon dioxide, catalysts used when manufacturing hydrogen and technology thereof, and environment purifying catalysts to decompose harmful substances, and technology thereof. The roles of catalysts and their technologies are expected in reducing the reforming temperatures, achieving energy saving, and reducing decomposition energy. Furthermore, the catalysts are expected of high activity, long life and low cost. Three themes were selected from the emergency and importance points of view. The themes are, in the consumer field, research and development of efficiency improvement in membrane reactors for reforming low-grade hydrocarbons to structure a technology to manufacture hydrogen for small-size portable fuel cells; and in the industrial field, development of hydrogen and carbon product manufacturing technologies with which CO2 generation is suppressed by means of the catalytic decomposition process. In practice, for such discharged harmful substances as dioxins, PCB and volatile organic compounds (VOC), treating them is the urgent environmental problem, and therefore, the fundamental research was taken up for practical application of the second-generation catalysts of the ultra-violet light and visible light responding type.

This research arranges recent public transport system technologies such as LRT, and clarifies their technical issues to be overcome and developmental courses, and the improvement effect of their energy efficiency and CO{sub 2} reduction effect by such measures to contribute to development of next-generation public transport systems. The outlines and features of LRT, monorail/trolley bus and AGT as existing public transport systems are arranged. In the EU, development of tramways using rubber tires is in promotion. The concept of a next-generation environment- friendly urban transport system is prepared based on features of every public transport system. Since a trolley system causes traffic congestion and environment deterioration, introduction of an independent transport system with fuel cell is necessary in the future. The technical issues and solutions for construction of the next-generation transport systems are analyzed. Fuel cell and ITS are important candidates. Substitution of the next-generation transport system for existing buses showed a CO{sub 2} reduction effect of 3.91 Mton/y in Japan. (NEDO)

For active environment technology export to OECD countries, needs for environmental measures in developing countries were surveyed. Both collection of environment technology needs in developing countries and preparation of technology seeds information of Japanese enterprises, and promotion of environmental projects by adding an information dispatch function are important. Active preparation and exchange of experiences and know-how of concerned enterprises, local governments and national organizations are also necessary. For development and possible export of small- and medium-sized ventures with excellent technologies and know-how, a suitable consulting system is essential for risks. For smooth promotion of warming prevention by international cooperation, active development of monitoring technology is also important. To support developing countries, OJT of persons in charge in technology transfer sites, and preparation of information infrastructure are necessary. Japan with much know-how on environmental preservation should positively participate in international standardization activities such as ISO. 10 refs., 14 figs., 56 tabs.

The research is conducted in cooperation with Industrial Technology Development Institute of the Philippines, and aims to solve water related problems such as unstable water supply and water quality pollution though developing a waste water treatment and recycling system which is easy to operate and maintain, low in cost, and usable in the Philippines. Fiscal 1998 is the second year of the project. Statistics are studied about the load that each industrial branch imposes on water for its pollution, and it is found that food manufacturers, paper pulp mills, and fiber dyeing plants are heavily responsible for water pollution. A method consisting of single-tower UASB anaerobic treatment and activated sludge treatment is applied as a water treatment process to Ram Food Products Corporation, and its optimization is studied. A removal rate 60% is achieved after a 12-hour treatment period at a COD (chemical oxygen demand) rate of 8g/liter/day. A method consisting of coagulating sedimentation and activated sludge treatment is applied to the waste water from a Solid Mill Corporation dyeing plant, when it is found that the water after ultimate treatment is almost colorless and that COD is 76mg/liter and BOD (biological oxygen demand) 13mg/liter, and these suggest that the waste water is recyclable. Since it is low in COD removing rate, the application of anaerobic treatment to high-concentration water after washing is not appropriate. (NEDO)

An environmentally friendly refuse energy utilizing business, for which RDF (refuse derived fuel) produced out of wastes discharged by industries belonging to a Fujieda city environmental protection council will provide the heat source, is proposed by the said council. The proposal is subjected to a study, a basic plan is drafted, and a decision is made on its profitability. In the study, surveys are conducted on the actualities of wastes and of demand for heat, and specifications are worked out relating to transportation and storage of RDF, production of steam by an RDF-fired boiler, routing of pipes for transmitting the steam to the industries in the district, facility costs, operating costs, etc. It is found that the amount of RDF produced out of the wastes discharged by the council member industries is so small that it can meet the demand of only one industry and that, even if more wastes are collected from a wider area, the increased amount will but meet the demand of two industries and a hot water pool. It is found that the system will be economically feasible, however, if the shortage of RDF-generated energy is covered by an oil-fired boiler and thereby impartiality is established in steam distribution and steam production unit price is reduced. In view of the intensification of control over dioxin, etc., the business will be gaining profit in 2002 and after. (NEDO)

Effects of the transfer of environmental technology were studied as an important policy for control of greenhouse effect gas in the Asian region. As schemes, those that were drew up by NEDO, JICA, etc. now exist and are used also in Japan. However, for the control of greenhouse effect gas emission which is expected to rapidly increase in future, it is indispensable to construct a new powerful and effective scheme in which technology transfer and fund to be given are organically connected. Especially, in the U.S., etc., the assistance of developing countries of a huge amount of money such as Japan's ODA is not extended. However, they position the environmental technology as an important strategy and is developing the assistance of developing countries by technology transfer and eco-business of private companies. Also in the eco-business field, the environment-related technology of Japanese companies is used in Asian developing countries, with expectations of its being a new business with international competitive strength. This is the subject for the whole global environment, and an important subject also for Japan which requires the creation of a new business field with international competitive strength. (NEDO)

For the purpose of contributing to working out a master plan for the introduction of the environmentally friendly type coal utilization system in the Philippines, analysis was made of the state of coal use/the state of spread by industry mostly including the electric power industry, cement industry and residential/commercial use fuel sector. In the Philippines, the amount of coal use has rapidly been increasing since coal-fired power plants started operation. For the promotion of the use of domestic coals, it is important to reform low grade coal. Moreover, the technology is required which copes with the reinforced regulation against SOx emissions. In the cement industry, coal and coal ash have not yet been effectively used. Therefore, the following measures should be taken to increase the competitive force: energy conservation measures, reinforcement of environmental measures such as dust prevention, and effective use of the fly ash emitted from power plants. In general households and small-/medium-sized industries such as tobacco drying, they still use a large amount of charcoals and firewood, which is approximately 86% of the residential/commercial use energy. There is a growing tendency for the development/spread of coal briquette as substituting energy. (NEDO)

An investigation was conducted into the systematical scheme for the introduction and promotion of environmentally friendly products mostly to the U.S., Europe and China. In the U.S., the introduction policy is given to one and all fields of the industry. The introduction policy of the U.S. has a characteristic that the introduction is left to the market principle by DSM or permit dealing, etc. except the preferential tax system and systematical finance in which the government is concerned. The policy of European countries is characterized by the idea preceding, standards or rules are first given, and the whole is pushed on to them. Accordingly, it seems that there is few atmosphere of expecting to receive the government side economic incentives from the corporate side. Legal regulations on the environment in China were prepared in a comparatively early time (1979), but the supervision of obeying the regulations and the appearance/spread of environmentally friendly product menus have just started. Accordingly, as the introduction policy on environmentally friendly products, there was found nothing valuable but the regulations. 12 refs., 3 figs., 15 tabs.

Efforts are made to grasp the parts remaining technically unsolved of the ozone-aided technology for creating a comfortable environment, such as ozone-aided enhancement of the decomposition of nondegradable organic matters in the urban sewage and industrial wastewater. Efforts are also made to put in order and analyze data about the said technology, to isolate the current problems and the objects of technical deliberation for the future, and to examine the feasibility of the introduction of this technology. Case studies were conducted for a novel ozone-aided system and the effect is examined of the introduction of ozone-aided treatment into crowded towns, water supply systems, sewerage, and industries that handle paper and pulp, chemicals, electric power, and foods. Findings are mentioned below. The ozone utilizing technology when introduced improves the efficiency of water circulation, reduces pollutants at an excellent rate, suppresses the generation of carbon dioxide, and enhances safety of water resources and water environments. To realize such good results, however, it is important for the ozone to be high in concentration, for the accelerated oxidation and enhanced biofunction processes to be further studied, and for the system to be optimized. It is also found that a technology of appropriate ozone storage will help enhance cost reduction. (NEDO)

The results achieved in fiscal 1992-1995 under the above-named project are stated. In the development of photocatalytic materials, a photocatalytic fluorocarbon polymer sheet suitable for use in a denitration apparatus is developed. A high density fluorocarbon polymer sheet composed of TiO{sub 2} modified with 0.3% of Pd/absorbent zeolite/fluorocarbon polymer PTFE (polytetrafluoroethylene) =48-63/24-36/10-20 is fabricated, which achieves a level higher than the denitration goal of 70%. Although the sheet in a 500-hour accelerated exposure test undergoes a hardening phenomenon in which elasticity decreases and tensile strength increases, yet degradation is hardly detected. Although a slight reduction is detected in denitration efficiency, yet it does not affect its practical application, and thus the durability goal is achieved. In the development of an energy conservation type air cleaning apparatus usable in underground parking areas or motorway tunnels, an apparatus capable of treating air at a rate of 2,000m{sup 3}/hour is fabricated, and this achieves a denitration level of not less than 80% in a field test (in the absence of rainfall). For denitration in the presence of rainfall, the apparatus is combined with an equimolar adsorption system, and a system capable of 80% denitration is proposed on the basis of data actually measured for each of the two. A conceptual design for a service model comprising a photodenitration and equimolar adsorption systems is evaluated, and it is found that it occupies less space than the existing models. (NEDO)

Two lectures were given by Christopher Flavin (vice president for Research, Worldwatch Institute Inc.) and Hiroshi Takeuchi (chairman, LTCB Consulting and Research Institute Inc.), and a panel discussion was held by five panelists with Toyoaki Ikuta (The Institute of Energy Economics, Japan) as the coordinator. The themes were 'a sustainable energy strategy for the nineties', 'industrial structure change and energy problem', and 'new energy and the global environment'. The panelists were from Sweden, France, Thailand, U.S.A., and Japan. The main subject was energy security, in which discussion was held on the uneven distribution of oil resources in the Middle East and political instability in the region and on counter measures against global warming problem. The discussion on the latter subject showed that a limitation exists in the total consumption of fossil fuel in the world, and that energy policies were meaningless unless they were on a global scale. As the concrete measures, energy conservation technologies and regenerative energy utilization technologies need to be developed and spread, for which emphasized was the spread on a global scale, namely, the necessity of international cooperation and an international propulsion system.

This project is aimed at development of optimum combustion technology with diversified fuels, e.g., naphtha and LCO, for gas turbines and others as power sources for topographical energy supply. The combustion under the microgravity is also investigated using the underground facilities at Japan Microgravity Center. Described herein are the FY 2000 results. For construction of combustion model and simulation, the combustion reactions for various liquid fuels are simplified to calculate ignition delay, adiabatic flame temperature and laminar burning velocity with an error less than about 3%. The microgravity combustion experiments are conducted for spray dispersed into a cylinder, to find flame propagation velocities changing with the vaporization characteristics of liquid fuels, and also to construct the combustion models. The premixed turbulent combustion simulation program is developed using a probability density function and analyzed. Development of new combustion technologies includes the study themes of flame propagation and combustion of the air mixture of the multi-component fuel in which the spray exists, combustion characteristics of the droplets of diversified fuels, and combustion of gas turbines with diversified fuels. A propane/air mixture shows different flame propagation characteristics whether it contains kerosene or LCO droplets. The effects of electrical field intensity in the combustion zone on combustion of fuel droplets are elucidated. (NEDO)

The paper outlined the present situation of industrial waste all over Japan and the present situation of industrial waste of large urban areas where it is most difficult to secure places for the final disposal, and conducted an analysis on the present and future amount of final disposal waste. According to the literature from the Ministry of Health and Welfare, `research report on the discharge/treatment situation of the industrial waste` and `research results of administrative organizations for industrial waste,` the situation of final disposal from the past to the present was outlined and analyzed to study the future trend. Out of the administrative divisions of Japan, four divisions, which are all typically called large urban areas, were selected, and the situation of industrial waste in large urban areas was outlined and analyzed according to the questionnaire survey and the literature on industrial waste obtained from each administrative division. The survey by the Ministry of Health and Welfare indicated that the volume of the industrial waste discharged from the whole country amounted to approximately 400 million tons in fiscal 1992. However, helped by the improving recycling of waste construction materials, the amount of final disposal around 2000 is presumed to be less by 20% or so than that in 1992. 58 refs., 5 tabs.

Two lectures were given by Christopher Flavin (vice president for Research, Worldwatch Institute Inc.) and Hiroshi Takeuchi (chairman, LTCB Consulting and Research Institute Inc.), and a panel discussion was held by five panelists with Toyoaki Ikuta (The Institute of Energy Economics, Japan) as the coordinator. The themes were 'a sustainable energy strategy for the nineties', 'industrial structure change and energy problem', and 'new energy and the global environment'. The panelists were from Sweden, France, Thailand, U.S.A., and Japan. The main subject was energy security, in which discussion was held on the uneven distribution of oil resources in the Middle East and political instability in the region and on counter measures against global warming problem. The discussion on the latter subject showed that a limitation exists in the total consumption of fossil fuel in the world, and that energy policies were meaningless unless they were on a global scale. As the concrete measures, energy conservation technologies and regenerative energy utilization technologies need to be developed and spread, for which emphasized was the spread on a global scale, namely, the necessity of international cooperation and an international propulsion system.

Researches were conducted aiming at the establishment of an ozone-aided highly efficient decomposition process for the persistent organic matters in municipal sewage and industrial wastewater. Tested for verification were advanced water treatment technologies of the biological function acceleration type and the effect of their combination with the accelerated oxidation method, conditions necessary for efficient operation, and water treatment apparatuses and systems for operating them at high efficiency. Some findings are stated below. With an ozone-aided process performed at the first stage of biological treatment, biological decomposition is accelerated for a rise in the persistent organic matter decomposition rate. This is nothing but a finding in the laboratory, however, and much remains to be disclosed concerning the optimum conditions, reforming of sludge to be generated, volume reduction of the same, etc. Another finding involves the acceleration of decomposition of persistent organic matters using ozone in combination with hydrogen peroxide, ultraviolet radiation, titanium oxide, and the like. There still remain numerous tasks to carry out, however, which relate to the investigation of the reaction mechanism, establishment of operating conditions and criteria for selecting oxidants, etc. As for ozone, remaining to be solved are the problems of generation cost, storage and preservation, and safety.

Technologies to purify polluted soils vary with kinds of pollutants, spread of pollution, and shapes of water veins. A method is used often that several wells are drilled in a polluted area, and water is circulated between upstream wells and downstream wells, where activities of microorganisms living in that particular environment are utilized to biodegrade the pollutants. This technology is called bioremediation. This paper deals with soil pollution by chemical substances, and describes development of a technology to remove pollution caused by PCB and petroleum which is thought difficult to apply the bioremediation technology among environment purifying technologies using microorganisms. The bioremediation of petroleum pollution assumes petroleum pollution on seashores. Discussions have been given on separation from sea water of petroleum decomposing microorganisms to be used in the bioremediation, and the number of petroleum decomposing bacteria in seas near Japan. As a result, it was made clear that a few kinds of bacteria will suffice for decomposition of main components in a mixture as complex as petroleum. 5 refs., 4 figs.

The present paper outlines the present situation of environment of developing countries, factors causing environmental devastation, and the influence in the international linkage as described in 1992 White Paper on Environment. The present environmental devastation is originated from national poverty. In general, as the results of imposing excessive pressure on the natural environment accompanying the increase of population or causing urban pollution due to the movement or densification of population, poverty brings about the reduction and devastation of forest, deterioration of soil, desertification, contamination of air and rivers, causing miserable situation. Prawn culture as primary export industry damages mangrove woods, and causes water pollution. Industrial development is rapidly spreading pollution of water and air. As for international relations, the net transfer amount of money in the flow of funds between advanced countries and developing countries is in the direction from the latter to the former due to payment of debts. In enforcing direct investment or overseas development aid projects, advanced countries must be aware of their responsibility, make efforts in grasping the situations of aided countries and perform sufficient environmental assessment. 5 refs., 8 figs., 11 tabs.

The paper grasped the state of coal utilization by coal consumption field, the state of coal physical flow in Vietnam, etc., surveyed/studied a possibility of introducing the environment friendly type coal utilization system, and assessed the possibility. As to energy resources, the north is abundant in hydroelectric and coal (mainly anthracite) resources, and the south in oil and natural gas resources. Coal production in fiscal 1997 is planned to be 10 million tons. Coal preparation technique presently available is only grain size sieving. Accordingly, it is necessary to study for heightening efficiency of facilities and modernizing facilities in accordance with the introduction of the environment friendly type coal utilization technology. During the study, it is possible to propose improvement on coal processing technology (coal preparation technology). Assessment and study are made especially of the coal selection system, fine coal recovery system and waste water treatment system. For the plan on new coal-fired power plants (300MWtimes4), there is left much necessity of proposing studying models considered of the anthracite combustion technology and environmental improvement and of assessing/studying them. 60 figs., 117 tabs.

This paper takes general view of the history of global environmental problems. A UN human environment conference was held in Stockholm in 1972, at which the human environment declaration and an action plan were adopted. The most important among the results of the Stockholm Conference were the treaty on international transactions of wild animal and plant species feared of extinction in the 1970's, the international treaty on prevention of pollution caused by ocean vessels, and the treaty on prevention of ocean pollution caused by dumping of wastes and other materials. Also adopted in the 1970's include the action plan to prevent desertification, the action plan on the world population, and the world weather plan. The UN Nairobi Conference in 1982 has sounded the alarm on the delay in tackling with the facing problems and the progress of aggravation in the global environment. In 1987, the ozone layer protection protocol was adopted. The earth summit at Rio de Janeiro in 1992 adopted the Agenda 21, with which the participating nations, autonomous bodies, and civil organizations have prepared their own Agenda 21, and are now about to begin challenging the global environmental problems. 7 refs., 4 tabs.

Development of conditions under which project financing (PF) functions is described. PF, a method with which funds are procured for a project on the security of the assets of and the cash flow involving the project, established its position as a popular financial means. Into the 1990, however, PF underwent a complete change, when it came to be actively employed as a means for the procurement of money for what is called `infrastructure building project for invigorating the private sector` in the developing countries. PF has now come to be utilized for the financing of projects in various fields besides the field of resources exploitation. In particular, PF is now utilized in schemes such as BOT (build, operate, transfer) in public enterprises, for instance, electric power utilities in developing countries. The gravest problem found in the private sector invigorating type PF is that the sponsor, operator, exporter, and lender on their respective levels are experiencing rising risks because of intensified competition in the presence of a great number of projects. Such risks involve the exchange rate, the completion of work, and the relations between the borrower and operator. 2 figs.

For the purpose of contributing to the resource recycling and global environmental preservation, the R and D of metal base scrap regenerative utilization technology were conducted, and the report on the finally obtained results was summed up. As to the technology to remove impurities by the solid phase treatment, the Cu removal rate of more than 96% was made possible by the low temperature fracturing technology, and that of more than 90% by the hue difference discrimination separation system technology. From the results of the FS on the low temperature fracturing technology applied to car scraps, it was found out that the present price condition is not economically efficient in the present price condition, but a possibility of achieving the removal rate of 54% in the initial plan was obtained if applying the hue difference discrimination separation system to the pretreatment. Concerning the Sn removal, the Sn removal rate of more than 70% was obtained by the gaseous phase sulfuration method, and that of more than 50% was obtained in Sn removal/Cu removal/Zn removal by the oxidation reaction method. The targets were achieved. Relating to the treatment of impurities by melting (liquid phase), the Cu removal/Sn removal technology under reduced pressure was effective in vacuum melting furnace of 2-ton scale, but the needs for the development of large capacity plasma torch were recognized in that of 40-ton scale for practical use.

This survey was conducted to estimate effects of drilling of geothermal exploration well on the environment, aiming at grasping the present state of environmental elements before the survey/development. As a result of the literature survey, the following distribution were confirmed in the fauna: 5 orders 10 families 19 species in the mammalia, 10 orders 25 families 73 species in the aves, 1 order 3 families 6 species in the reptilia, 2 orders 6 families 9 species in the amphibia, and 17 orders 179 families 719 species in the insecta. In the flora, a distribution of 132 families 670 species was confirmed. The results of studying the above indicated that in the fauna, there were 10 species such as antelope as valuable animal in the area surveyed and that it is necessary to pay much attention to the environmental preservation of the habitat for those animals in the well drilling associated with geothermal survey. In the flora, the 13 valuable animals selected as animal having a fear of extinction in the 'plant-version red list' were confirmed in the area surveyed and the periphery. Further, as to the plant colony, there are no important colonies in terms of preservation. In well drilling, important things are efforts exerted to restore to the original state of the area altered, prevention of the washed-away of mud water, etc., and efforts exerted to preserve the environment of vegetation.

The research aims to develop materials and apparatuses for the purification of atmosphere using titanium dioxide that exhibits a powerful oxidizing capability when irradiated with light. A study is conducted to find out an optimum composition for a photocatalytic fluorocarbon polymer sheet suitable for use in a denitration apparatus. A high density fluorocarbon polymer sheet composed of TiO{sub 2} modified with 0.3% of Pd/absorbent zeolite/fluorocarbon polymer PTFE (polytetrafluoroethylene) =48-63/24-36/10-20 is found to show high denitration efficiency, and this achieves the denitration efficiency goal. As for sheet thickness, 0.75mm is found to be enough. The sheet experiences some hardening in an accelerated exposure test, but does not change much in a surface gloss test or a chalking test. Although a slight reduction is observed in denitration efficiency, yet the durability goal is achieved. In the effort to develop an energy conservation type air cleaning apparatus, field tests and experiments are repeatedly conducted. As for photodenitration in the cleaning apparatus, the number of photodenitration stages and the magnitude of equimolar adsorption area necessary for achieving an 80% denitration rate is calculated from the relations of the NOx concentration profile and the denitration rate in the equimolar adsorption module to (gas flow rate/module surface), and the result shows that the initially intended goal is achieved.

This paper describes the achievements in fiscal 1998 in developing environment friendly catalyst technologies. Development was proceeded in a water decomposing hydrogen production system of double tank system utilizing visible lights. The system connects combination of visible light responding type semiconductor powders with an oxidation and reduction mediator via a membrane (consisting of a hydrogen ion permeating membrane and an electric conductor). Discovery was made on two sets of semiconductor-mediator combinations (to produce hydrogen and oxygen) that meet the requirements. A composite oxide powder catalyst of nano structure was also realized. Verification was made on water decomposing hydrogen production by using multi-layered membranes composed of a hydrogen producing catalytic membrane, a semiconductor membrane, and an oxygen producing catalytic membrane. By using selective oxidation that uses trace amount of nitrogen dioxide as a gaseous phase catalyst, such good results were obtained as conversion rate of 10%, and selection rate of 27% in methanol and 23% in formaldehyde. Selective oxidation mechanisms in iron carried silica and oxidized tin were elucidated theoretically and experimentally. It was elucidated by calculating chemistry that effect of adding nitrogen dioxide lies in draw-out of hydrogen, NO is involved in draw-out of O from CH3OO, and NOx is involved in synthesizing formaldehyde from CH3O.

A survey was made to study possibilities of Japan`s cooperation in tackling energy/environment problems in Asian countries. In 1995 the GNP growth rate was 2.6% in the world, while it was 7.9% in Asia showing a rapid growth. With the accelerating industrialization and urbanization, energy demand is now over three times as much as that in the 1980s. This means increases in waste and environmental pollution. Especially, the use of firewood in non-electrified areas is a serious problem the same as the slash-and-burn farming and deforestation. Also relating to the production of electric power, it is inevitable to choose hydroelectric power and renewable energy in addition to fossil fuels. Therefore, the necessity is heightening of various technologies for it and environmental protection technologies such as coal cleaning. Local areas, where the population density is extremely low and the electrification cost is high, became victims of elecrification. There the power system should be shifted from the central supply system to the local distributed one. For it, it is necessary to recognize an importance of the distributed type renewable energy which is friendly to the environment. The paper outlined the state of each country and energy by policy and environment. 10 figs., 83 tabs.

Evaluation for committed effective dose due to dietary foods by the intake for Japanese adults

Explained are the internal exposure (IE) in Japanese adults due to the ordinary intake of food and the committed effective dose (CED) derived from it, which can be the basic reference data for estimating CED at emergency like the recent Fukushima Disaster. IE lasts as long as radioactive substances exist in the body and its health risk is assessed throughout the lifetime, 50 years in adult and in children until their age of 70 years, by CED based on consideration of the physical and biological halftimes of radionuclides involved. CED (mSv) is calculated by an equation given in International Commission of Radiological Protection (ICRP) Pub. 72, using radioactivity level (Bq/kg), intake (kg/y) and age-dependent dose coefficient (mSv/Bq). Japan MEXT in its homepage (http://www.kankyo-hoshano.go.jp/) publishes the states of environmental radioactivity levels including those of daily Japanese food. The food survey of yearly changes of radioactivity level (Bq/man/day) indicates that, when compared with the level in 2009, it is two times higher in 1970s due to old in-atmospheric nuclear experiments, and is decreased gradually with a temporary peak around 1986 by Chernobyl accident. Studies on certain natural and artificial radioisotopes in 240 kinds of current food in 1989-2005 reveal that Po-210 level in fishes and shellfishes is particularly higher than others like St-90, Cs-137, Rd-226, Pb-210 and so on. CED in adults is calculated from yearly intake of foods (kg/y), their radioactivity (Bq/y) and the coefficient above, to be 0.80 mSv, and 0.98 mSv when the contribution of K-40 is taken in calculation. The proportion of the contribution in the latter estimated CED accounts for 74% (0.73 mSv) by Po-210 and for 18% (0.18 mSv) by K-40, which is conceivably derived from intake of more seafood by Japanese than other people in the world (average 0.070 and 0.17 mSv, respectively).

This promotion project on the cooperative research aims to efficiently extract and recover valuable metals (gold, silver, copper, rare metal, etc.) including in large quantity in tailings of ores in the Republic of Kazakhstan. In FY 1995, conducted were the field survey, support study in Japan, acceptance of researchers from Kazakhstan, conceptual design of pilot plant, etc. The ore/mineral for Cu is mainly an alteration ore of chalcopyrite. Au and Ag are low grade and unknown, and the main gangue mineral is pyrite. The low grade ore (waste/much) of the Nikolayevska mine has a tendency to leaching at normal temperature, but the ore of mostly chalcopyrite such as tailings from each place has difficulty in leaching. It gets leaching by increasing temperature. The more the temperature rises, the more conspicuous the reaction becomes. Further, chalcopyrite is leached with priority over pyrite. From the result, a technical potentiality was obtained of leaching of low grade chalcopyrite in tailings mostly of pyrite. The existence of Thiobacillus ferrooxidans was confirmed. As to the recovery method for Au and Ag, CIC is studied. The process of waste/much is solvent extraction, electrowinning study and leaching, and that of tailings is bacteria leaching and leaching study. (NEDO)

An investigation was conducted with the aim of elucidating the foundations for effective utilization of environmental pollutants or unused resources which are likely to be causal substances of environmental pollutants, as resources, using biotechnology. Composting of agricultural waste, production of microbial mycelium proteins and microbial fermentation materials were suggested as main examples of effective utilization of unused resources by microorganisms. Selection of active microorganisms in the livestock waste, clarification of the mechanism of action and the establishment of treatment conditions are essential to new developments in this field. In the field of marine products industry, it was pointed out that the recycling of waste using microorganisms and enzyme treatment is the most promising approach to the effective utilization of resources. In the field of food industry, applications as the culture media for mushrooms, for enzyme production and for the production of physiologically active materials as well as fuel were clarified.

Efforts are made to develop the above-named technology so as to improve on performance of magnetic materials for magnets extensively used in electric motors to consequently influence their energy conversion efficiency. For this purpose, probes are conducted into novel alloy phases, intermetallic compounds, and microstructure in a containerless coagulation process in which a molten body of a magnetic metal material in free-fall is allowed to cool rapidly, and a system is developed to enable a series of processes of heating and melting in preparation for containerless coagulation, specimen formation, and then coagulation in a microgravitational environment. The system is used for the study of novel materials for magnetic alloys and process technology. For the utilization of containerless coagulation in a microgravitational environment, it is necessary to make full use of the JAMIC (Japan Microgravity Center) facilities, and an experimenting apparatuses are fabricated for a containerless coagulation process and unidirectional coagulation process applicable to a free-fall test. In this fiscal year, some significance involving for example structural uniformity are found among the specimens created using containerless coagulation in a microgravitational environment, and it is inferred that the data as an index of higher performance will lead to studies in the next fiscal year and afterward.

Assessment and examination were conducted on the scientific/technological aspect, environmental aspect and economic/social aspect concerning measures for mitigating climate change, as a part of international cooperation in global warming issues. In the development of assessment methods for cost analysis, it revealed that, in the activities for mitigating emission of greenhouse effect gases (GHG) or for increasing carbon sequestration, benefits of the mitigation sometimes surpassed their cost, allowing the society to benefit from the mitigation. In the examination of problems in technology transfer and their solutions, it was found that, in order to attain successful transfer, partnership among the parties interested was essential and that each government was capable of promoting such partnership. In the assessment of various policy options, the situation in the U.S. is such that the market aspect of GHG emission permit and credit trading is rather weak because of immaturity in a legal framework on GHG emission trading and because of undefinedness in the systems of the Kyoto Protocol and in the possibility of its validation. However, the reason enterprises are actively participating in the early market is that they plan a risk-hedge for example in anticipation of tighter regulations in the future. (NEDO)

The dye finishing operation in the textile industry places heavy load on the global environment. This paper describes the achievements in fiscal 1998 on development of process to eliminate the load. Low-temperature plasma treatment was introduced into the desizing and refining process to develop a continuous treatment process using no water and chemicals. Quality equivalent to that produced by conventional methods was obtained by applying an appropriate plasma treatment condition. The energy saving rate was presented by reduction by 84.3% converted into steam. Conventional dye finishing operation uses three to six times as much water as the cloth weight. The developed air flow treatment device reduced the water ratio to less than one. This is 86.0% reduction of energy consumption converted to steam. In removing pectic substance in cotton refining, no water, chemicals and steam were used, but were substituted by enzyme for continuous treatment. Good finishing result was obtained by performing bleaching and dying. Enzyme cost is an issue, but the cost would decrease if it is used in large quantity. A two-dimensional colorimeter (measures cloth color with high clarity and reproducibility) and an automatic dye preparing device (with high volume measuring performance) were developed. If the cost required for re-coloring under the present inspection method is converted into energy, it corresponds to 81.6% reduction. (NEDO)

This paper describes the achievements in fiscal 2000 in investigating generation mechanisms and suppression of dioxins from refuse incinerators, and in investigating non-bromine flame retardant materials (having a possibility of generating hazardous material such as bromine-based dioxin during combustion). To produce poly-chlorinated dibenzo-para-dioxins (PCDDs)/PC dibenzo furans (PCDFs) (dioxins, but not containing Co-PCB) in a small fluidized bed combustor for simulated refuse derived fuel (RDF), both of chlorine source and hydrocarbon are required. If the primary combustion furnace temperature is high and the air excess rate is low, the concentration of the dioxins increase. In addition, since oxygen shortage in temporal and spatial locals or excessive concentration zone of unburned hydrocarbons imposes great effect, promotion of turbulence mixing is important. In producing dioxins, vaporization from dust due to interference with the combustion gas, and copper and iron catalysts have great effect, whereas SOx in the combustion gas has suppression effect. Flame retardant materials can provide specific flame retardation effect to particular plastics in a temperature zone slightly lower than the combustion temperature. The paper also describes development of new flame retardant materials. (NEDO)

The paper studied the working-out of the basic plan on the RPF (refuse paper and plastic fuel) production business in the area mainly including Nagoya city and of the business profitability. RPF is a solid fuel made by grinding, mixing and pressurizing paper and plastics in appropriate sizes. Its shape and calorific value can be adjusted according to the needs. In the Nagoya area, the demand for RPF is more than the supply, and therefore a much larger amount of RPF is in need. In Phase 1, business was studied for paper and plastics in the container packing paper waste and business-derived general waste. As a result, the RPF production amount was 21,000 t/y, which is equivalent to the effect of reduction of the same amount of coal. As to the profitability, it was made clear that the business can be profitable if collecting 41,400 yen/ton as the re-commercialization cost. In Phase 2, the design of the facilities was made for the larger-sized commercialization by adding industrial waste plastics to the waste in Phase 1. (NEDO)

Noticing that metal oxides have photocatalysis for reduction in NOx concentration and examining effects of the TiO2 selected on removal of pollutant, the paper proposes a direct purification method for the air environment. Since TiO2 causes electron excitation meeting near ultraviolet irradiation, it manifests a catalytic function for various oxidation/reduction reactions. Details of the reaction mechanism are unknown, various active oxygen species generated on the surface of TiO2 under light irradiation oxidize NOx and acquire it as nitric acid on the surface. It is found that mixture of activated carbon of low hygroscopicity with TiO2 is effective to prevent a tendency of NO to desorb before NO becomes nitric acid. What 40% of the catalyst with fluorine resin is formed into like a sheet shows a high removal rate even in the amount of ultraviolet irradiation in a winter cloudy day in the wide range of 0.5 - 95.0% of NOx and SO2, and if the photocatalyst is applied to the side wall of city buildings, the NOx concentration is estimated to be reduced by as much as 20%. 5 refs., 3 figs.

Two articles of 'Care of coppice in Wood Totoro' and 'Global environment protection from the universe' are included in this report. The former explains the necessity of coppice conservation through an example of Sayama Hill in Tokyo. Until the time 30 years ago, coppices are deeply related to people as the places which supply fuel and fertilizer to villagers, but they have been left or cut down by energy source conversion and development of home lots. Now we must learn the traditional methods of caring coppices again and find a new sense of values regarding the nature. The latter introduces satellite-used remote sensing which allows to continuously scan all the areas of the earth within a short period for global environment protection. This sensor uses a wide range of wavelengths from light to radiowave. In the U.S., it is operated in the name of LANDSAT since 1972, and Japan is also operating various kinds of satellites for environment research concerning, e.g., CO2 concentration and resource exploration. 10 figs.

Naturally, a human being has a rhythm with a period of about one day for hormone distribution and body temperature. This rhythm is called circadian rhythm. An ecological watch controlling this rhythm exists in supraoptic nucleus of brain, and its inherent period is clarified to be about 25 hours. Light, temperature, sound, smell and the like are the elements to improve arousal degree of brain and adjust the interior watch. However, a strong light does not only have the direct effect on improving immediately arousal degree and performance but can also shift the interior watch. Specifically, the interior watch becomes slower when a human body is bathed in an intensive light in midnight, whereas it becomes faster when bathed in an intensive light at daybreak. Consequently, this phenomenon can be used to shift the sleepy peak of a person on night duty from the working time to daytime sleeping time zone. The technology using light to improve arousal degree is utilized in space shuttles, atomic power plants, petroleum refineries and the like in USA. (NEDO)

This paper summarizes mineral waters as commercial products, and the manufacturing facilities thereof. The most widely used pattern of packaging mineral waters is to use either PET bottle or back-in box. The manufacturing process consists generally of: rough filtration of natural water, storage, activated carbon filtration, filtration, sterilization, ultrafine filtration, warm water bottling, capping, cooling, cartoning, storage, and shipment. The rough filtration removes sands. The activated carbon filtration removes water soluble organics. The sterilization is carried out under conditions of retaining the water at 75{degree}C for 15 seconds or retaining at 120 to 140{degree}C for 2 seconds. The ultrafine filtration uses a ceramic filter with a thickness of 0.2{mu}m. Sterilizing harmful microorganisms uses heating operation and filters to remove bacteria. An example may be cited that uses a bio-clean room for the purpose of controlling the harmful microorganisms. Subject microorganisms include a variety of viruses, rickettsia, bacteria, and fungi. The super-high performance (HEPA) filter used in the sterilization is demanded of collecting dusts with sizes of 0.3{mu}m or larger at a collection efficiency of 99.97% or higher. 3 refs., 4 figs., 1 tab.

This paper explains mechanism of biomethylation of such elements important in environmental science as As, Hg, Sn and Pb, and its significance in the environmental science. Biomethylation is a process to bond methyl group directly to metals by actions of living organisms, which is occurring widely in the natural environment. Addition of methyl group onto metallic elements has a high possibility of changing their chemical and physical properties and increasing their movability, thus affecting the geochemical circulation. Particularly, such elements are important for the environmental science as As, Hg, Sn, Pb, Se, Te, Ge, Sb, P, S, and Cl. Deposits in water zones which have been regarded previously as final settling places for heavy metals are active media for anaerobic bacteria which can cause methylation. Important molecules involving in methylation are S-acenosylmethionine (SAM) and methylcobalamin which is a derivative of vitamin B12. The SAM is regarded as sulfonium salt, and the methyl group is transferred as a carbocationic intermediate. 106 refs.

This paper explains the ecology of wild birds, and describes a number of attempts at the Gyotoku wildlife sanctuary to build wetland environments for waterfowls to live. Many of wild birds use shallow marshy grounds, rivers, ponds, and tidelands as their place of living. There are not only birds living on fishes, but like wild ducks those living on plant seeds, algae on mud, and small animals. Others live on shellfishes and insects. Their environmental conditions for hatching and breeding are also a large factor. Among the `estuary area sets` where these environmental conditions are available, the continuation of tidelands is now endangered. One example is the Shinobazu pond in Ueno, Tokyo. Fulica, for example as a representative bird living at swamps, requires vegetation around its living area, affluent submerged plants, an open area with a radius of at least 200 meters to be available, and water depths from about 0.5 m to 2 m. At the Gyotoku wildlife sanctuary, long-lasting observations are continued at several test ponds having different conditions and water qualities. 4 figs.

In the Kuwanosawa area, Yuzawa city, Akita prefecture, survey was conducted to grasp effects of drilling for structural boring in the geothermal survey on the peripheral environment. In the survey of animals, there were 5 orders/10 families/19 species of mammals and 10 orders/25 families/73 species of birds. Three kinds of precious animals were confirmed. There were 132 families/6,670 species in the flora. Three kinds of precious plants and three kinds of precious floras were confirmed. During the survey, drilling for structural boring was conducted. At three spas for survey, there were recognized some survey items of which there were great fluctuations. However, those are seasonal valuations or valuations related to the situation of the inside of hot springs. It is not recognized that the fluctuations were caused by the drilling work and pumping-up of geothermal water. The noise made during the well drilling was reduced around the well as theoretical values indicated. At a spot 200m away from the well, the noise was reduced from the environmental standard, and accordingly, it seems that there are few effects on the peripheral environment. The vibration was reduced around the well more than theoretical values indicated.

The Chubu International Airport is positioned as a hub airport scheduled to start its use in the early part of the 21st century, to which introduction of large-scale cogeneration systems was discussed. Structuring an energy supply system conscious of the 21st century is intended, that is friendly to the environment, is attached with importance on the economy, and has high reliability and safety. The systems have cogeneration capacity from 4,500 to 6,000 kW, and utilize high-pressure waste heat from the cogeneration system as the heat source. The system uses the high pressure waste heat, stored heat, and gas at the same time to achieve high economic performance brought about by heat storage and the best energy source mix, while attempting cascade utilization of the heat. Considerations were given to suppress the environmental and energy load on the district as low as possible for the coexistence with the district, and to build framework and coordination to return the merits to the district. Subsidy introduction also has a great effect to assure the economic performance. The optimal specific construction of the system was found in combining the utilization of energy generated from temperature difference in sea water as a heat source system, the topping system utilizing the high pressure waste heat available in the system, high-efficiency heat pumps, and the heat storing system utilizing electric power available at late night.

Identification of noise and vibration levels and evaluation on environmental effects were performed in association with the excavation in the geothermal investigation well drilling point (well N11-MD-3) and the vicinity thereof in the Busadake area in Hokkaido. In the survey, noise and vibration were measured before and during the well excavation at the well drilling point and nearby four points (boundary of the drilling premises, 500-m point, Kawakita Spa and the entrance to the mountain stream of petroleum). In addition, a distance decay survey was carried out at five points in one direction from the well drilling point. The result of the noise measurement showed the value of about 30 to 50 dB before the well excavation at the drilling point and its vicinity, and about 40 to 60 dB during the excavation. The vibration was about 40 dB at the boundary of the premises during the excavation, whereas the places other than them showed the lower limit of measurement. In the distance decay of the noise, 75 dB at the 10-m point decayed to 50 dB or lower in the 200-m point, while the vibration level of 75 dB decayed to 30 dB or lower in the 100-m point. These facts lead to a conception that the noise and vibration in association with the well drilling would not give great influence on the neighboring environment. (NEDO)

The paper described the present situation of the waste treatment system for the environmental engineering and the problems. The final waste treatment plants are in the tighter and tighter condition, and therefore the waste treatment system ought to be changed to a system in which importance is placed on the size reduction, weight reduction, and recycle. Accordingly, the waste treatment system becomes more characterized as a resource feedback process, and should be given more credit as a system for production of secondary resource. The problem is arrangement of conditions of technology, cost and legislation system for smoothing such recycling flow. Of course, it is natural that the most important subject of the system is to secure the environmental preservation by the waste treatment. As future subjects, needed are understanding of the waste treatment as a resource reproductive system, relation with other industries, and review of the legislation system. In consideration of technology, cost and environmental loads, required are proposal of validity of the recycle level limit and a future image of the system structure, and policies for promoting and supporting the recycle business. 47 figs., 104 tabs.

To reduce SOx with coal utilization, a desulfurizer is introduced in Thailand as diffusion activities in the demonstration program. The purpose is to reduce the environmental pollutants. For this desulfurizer, lime mud mainly composed of lime stone is used as an absorber. SO2 in the flue gas is absorbed by the slurry of lime mud, to form calcium sulfite. The calcium sulfite blown in the bottom of recycling tank is oxidized by oxygen in the air, to form gypsum. The gypsum is recovered as a by-product. In this fiscal year, a feeder of lime stone, spray nozzles, and various analysis apparatuses were supplied. Supervisors for electric instrumentation/control were also dispatched as well as for main body construction, to carry out the instrumentation setting works, check of sequences, and adjustment of apparatuses. After the test operation, supervisors for the demonstration operation were dispatched up to March 1998, to conduct the cooperation works between Japan and Thailand sides. Thus, successful and successive demonstration operation was confirmed. 21 figs., 6 tabs.

Measurements were carried out on three buildings having different heat insulation, airtightness and heat capacity for testing the hot heast enviroments (having a room size of about 4.6 m{times}3.7m{times}2.3 m) as to the temperature differences between the upper and lower parts of the room and the MRT (mean radiation temperature, representing the temperature of radiation from the wall face). These are compared according to types of heating appliance. The result is summarize as follows: The temperature difference in the upper and lower parts is affected largely by the airtightness of the building, the difference being capable of getting reduced by rasing the airtightness even in a buildings low in heat insulation. In a building with low airtightness, type of heating appliance and its installation location affect the temperature difference. The MRT is determined determined nearly completely by the heat insulation of the wall face in a room, but it tends to be affected easily by the specification and area of windows. A floor heating system increases the MRT and generates very little difference in temperatures in the upper and lower parts of the room. A comparison using a PMV (one of the indexes for enviromental comfort in a room) was also conducted. 12 figs., 7tabs.

For global scale measures to be taken for environmental protection, it becomes more and more important in the future to positively transfer and spread energy conservation technologies of Japan to overseas countries. Especially, it is effective for both economic growth in the Asian region and global environmental protection to transfer technologies which the oil refining industry has been developing and accumulating. Energy conservation in the oil refining industry means the energy conservation by strengthening the operational control at the first and second oil crises in the first stage, the energy conservation in the second stage which was accompanied by small and medium scale plant/equipment investments during several years after the first stage, and the energy conservation in the third stage which was accompanied by large scale investments from the first half of the 1980s to the present, resulting in improvement of 40% over before the first oil crisis. As to environmental protection measures, measures to reduce waste from oil refinery against air pollution and water pollution were prepared by the first half of the 1970s, and technologies were established of waste water treatment, flue gas desulfurization and denitrification. A lot of facilities for improvement of product quality and for low pollution were installed. In addition to environmental technologies, also in other industries, there were seen the heightening of thermal efficiency of kiln and thermal efficiency of cooling technique of clinker cooler in the cement industry and the improvement of productivity in the paper/pulp industry. 360 figs., 62 tabs.

For grasping the characteristics of weather, climate, and natural earthquakes in and around the geothermal survey area in the Appi district, Iwate Prefecture, observation data of weather stations or the like in the neighborhood were collected and put in an easy-to-use order. Weather and earthquake data of the 1990-1999 decade were collected and subjected to statistical processing. Weather in the Appi District Survey C area is characterized in that it assumes the Japan Sea side pattern with much snow in winter and much rain in the rainy season. In the other seasons, however, it assumes the Pacific side inland pattern. Weather data in the Appi district and its vicinity are deemed to be similar to the values observed at the Hachimantai weather station. The area covered by the survey, however, is higher than the Hachimantai weather station by 400-900m, and therefore is that much colder and has more rain and snow. As for earthquakes, a total of 647 were recorded in the decade 1990-1999. In the Appi District Survey C area, which is approximately 20km times 20km large, suffered 31.1 events/month in 1998, which indicated a great rise in seismic occurrence. The rise is now attributed to the volcanic activity of Mt. Iwate which is deemed to be waning. (NEDO)

Energy efficiency of construction machines is extremely low, because engines cannot follow sudden load changes. Solution is sought by developing a construction machine using as the motive force source a hybrid unit composed of an engine, a generator and batteries. The activities were advanced in the following five fields: (1) analysis on loads on existing construction machines, (2) development of hybrid move force unit, (3) development of an actuator device, (4) development of a control system, and (5) development of a hybrid construction machine simulating system. In Item (1), a control work on a 6-ton class hydraulic shovel was selected as a representative work, whereas the work was divided into seven modes to measure such output characteristics as fuel consumption and actuator output in each work, and the standard work load modes were established. In Item (2), motive force in the set load modes was measured to discover functional requirements on the motive force unit. In Item (5), the simulation model for the existing machines was used to evaluate the fuel consumption performance of the motive force unit. (NEDO)

Surveyed are the roles of the government, important for environmental buildup for technological innovation. The U.S. research and development support programs are classed into contracts, grants, cooperative agreements, and CRADAs (Cooperative Research and Development Agreements). The government financially supports the first three, but not CRADA. It provides CRADA with manpower, facilities, and resources. The research and development (R-and-D) appropriation not for national defense in the U.S. fiscal 2000 budget is up 36% to $39.4 billion occupying 50.6% of the total R-and-D expense. The basic research appropriation is given the highest priority, enjoying an increase of 4.7% to $18.1 billion. In the U.S., taxation for R-and-D expenses is done in two ways. One is a research expense tax deduction system under which R-and-D expense is handled as a cost, a subject of deduction. The other is a research and experiment tax deduction system under which a certain percentage of R-and-D increment is free of taxation. NEDO's (New Energy and Industrial Technology Development Organization) system for national R-and-D projects is scheduled to change extensively upon reorganization of the government ministries and agencies in January, 2001. Under the circumstances, the current and future systems of the state supports for R-and-D are outlined, and the position of NEDO in them is clarified. The R-and-D systems of the entrusted businesses and the problems they contain are also described. (NEDO)

A large quantity of coolant is used in the grinding process for ensuring high accuracy and quality in the work. This presents a serious problem from the viewpoint of environmental impact or energy conservation, and now environment-conscious grinding methods requiring no or less coolant are sought for. With a view to answering the demand, efforts are exerted to put to practical use, and improve, an EcoloG grinding technique. The goal is to reduce to half the energy that the grinding process is now consuming. The EcoloG technique is a grinding method under which vegetable oil mist is cooled for lubrication and a small amount of cooling water is fed to the point of grinding for removing chips. In fiscal 1999, a survey was conducted on technical literature, patents, and the like in and out of Japan for the study of the actual state of dry machining, and then the course of future studies was clearly established. Studies were also carried out aiming at the practical application and improvement of the EcoloG grinding technique, and the technique achieved a quality level as high as that of the conventional coolant-aided method in a process of grinding a shaft to have an accurate outer diameter by use of an ordinary wheel head.

This survey is intended to utilize cogeneration to promote structuring a system to effectively utilize potential energy in a district. In connection with the total rebuilding plan for Yatsushika Hospital, a proposal was made on a cogeneration district heat supply system that could be introduced to six facilities in total including the hospital, its three ancillary facilities, and two neighboring facilities. The proposal is intended to evaluate energy conservation performance, environmentality, and economic performance of the system, and structure an optimal system. Two gas engines having the same capacity were selected as the driving source of the cogeneration system. The waste heat recovering system adopted the 'hot water plus steam recovery system'. Generators were selected that have high energy saving and overall cogeneration efficiency, power dependence, heat dependence, and waste heat utilization factor. As the countermeasures for heat load that cannot be taken care by the waste heat recovery alone, discussions were given on the cogeneration plus gas-burning absorption type cold-hot water device system (the system 1) and the cogeneration plus heat pump heat storing system (the system 2). As a result, the system 2 was selected as the optimal system because it uses both of LNG and commercial electric power effectively, and has stability against variation in fuel prices and excellent environmentality.

Pursuant to the COP3 (Third Session of the Conference of the Parties to the United Nations Framework Convention on Climate Change) protocol, studies are conducted on a district cogeneration station for Radom City, Poland. Using the annual load pattern of heat supply, cogeneration will be built only for the amount that covers utilization factors not lower than a specified level, and the shortage in winter when the load is heavy due to demand for heat will be dealt with by the existing hot water boilers. Daily change in load is to be covered by a new, additional boiler which will bear 20% of the whole output. The system is a natural gas fired turbine cogenerator, and hot water is supplied by a waste heat recovery boiler. Cogeneration will cover 80% of the annual heat supply. As for heat supply capability, it is set at 72MWt with the additional boiler taken into account, and 35MWe is to be generated. Heat efficiency will increase to be higher than 80%, coal consumption will decrease, and 28,117 tons/year in terms of oil will be saved with the increase in natural gas consumption subtracted. CO2 reduction will also be as large as 206,000 tons/year, decreasing air pollutants. Provided that 4.336-billion yen for facilities are financed by Japan's environmental yen loan, Poland's National Fund, and Radom City's own fund, IRR (internal rate of return) on investment will be fairly good at 10% in 30 years of operation. Investment will be recovered in nine years and there is no problem in cash flow. (NEDO)

With the advancement of information technologies, multimedia information terminals such as handyphone systems and mobile computers are increasing in number and improving in quality, sharply increasing power consumption in this domain. So as to suppress the power consumption, efforts are exerted to develop technologies for information terminal LSI (large-scale integration) substrates consuming extremely low power and still capable of high-speed operation. Studied are a device technology of SOI (silicon on insulator) to realize a remarkable reduction in power consumption and enable high-speed operation and a circuit technology of the multi-threshold CMOS (complementary metal-oxide semiconductor) advantageous to the achievement of low-voltage high-speed operation. In concrete terms, the efforts center about an extremely thin film SOI device of the full depletion type higher in transistor driving capability, lower in load capacity, and smaller in surface area than those currently in use, and aim to put such an SOI device on an optimized multi-threshold CMOS circuit for the establishment of techniques toward the embodiment of an LSI substrate consuming extremely low electric power.

The energy and environment issue was considered from a viewpoint of human happiness. The paper picks up economy, philosophy, energy and humans as organisms, and considered how the principle of the increase by geometrical progression plays an important role in these. That the repetition in phenomena is like the increase by geometrical progression means that changes increase not linearly but exponentially and nonlinearly and bring such large changes as are unimaginable. The increase in entropy, which is caused by a nonlinear increase of the state, is an irreparable change. The problem of the pursuit of happiness also cannot be solved by the linear thought. The energy and environment problem cannot reach the solution in an extension of the linear thought in which humans have overcome poverty and lacks since the past and pursued richness earnestly. Namely, it is necessary for the 21st century to stop thinking of the energy utilization for seeking for much more richness and to try to think the energy issue in the social system where happiness with not too much richness is presupposed. 16 refs., 1 fig., 1 tab.

This paper explains the concept, history, and analytic methods of life cycle assessment (LCA), showing its application to beer bottles and cement factories as specific examples. The LCA is a method to calculate substances and energies put into the whole process of production of a product from raw material mining to product wasting and environmental loads emitted therefrom. It also evaluates the result collectively and quantitatively. A first case of the research is reportedly the one performed at Coca-Cola Co., Ltd. in 1969. Full-scale researches have gone forward in European countries in the recent several years, and are progressing to international networks. The analytic methods can be divided largely into an accumulation method to analyze data in each process and add them up, and a method to use an industrial association table. The former method is the most generally used method currently in overseas countries if referred to the LCA. Because the LCA can cause the analytic result and evaluation to vary depending on the purpose, it is important to define the goal, and set the scope. The LCA must develop in the future although it has a number of problems. 10 refs., 5 figs., 2 tabs.

Ground improvement using fibredrain (FD) material has not been used in Japan. For its practical use in Japan, laboratory experiment was made on such technological characteristics of FD material as tensile strength and permeability, and field test was also made to verify its improvement effect. A plane FD specimen of nearly 90mm wide and 9mm thick is composed of a folded double jute fabrics band and 4 twisted coir ropes arranged between the jute fabrics at even intervals, and the band is sewn up along center lines between the ropes. A mean permeability coefficient is estimated to be {kappa} = 1.0times10{sup -1}cm/s and {kappa} = 1.0times10{sup -2}cm/s at {sigma}{sup 3} = 0.5kgf/cm{sup 2} and {sigma}{sup 3} = 2.0kgf/cm{sup 2} in lateral pressure, respectively, showing sufficient permeabilities for vertical drain material. The tensile strength of fresh FD material is estimated to be a little stronger than 900kg/material width which is far stronger than that of conventional FD materials. The field test result showed that the FD material achieved the target for ground improvement, and has sufficient functions as a substitute for SD material. 6 refs., 10 figs.

With developing countries (APEC countries) as the main objects, investigations were carried out to issue environmental technology transfer information that Japan has accumulated, and advance exchanges of technical information with persons related inside and outside Japan. As a result of the investigations, it was found that the environmental technology information that serves more effectively for the developing countries is the technical information that has been developed by repeating improvements, has provided actual results in work sites, and is actually used, rather than the state-of-art technologies. Based on this result, business entities having factories and operation centers located in Mie Prefecture and the city of Yokkaichi were asked to provide data for the actually used environmental technologies. Out of 51 items provided by 17 companies, nine items were selected to be used as prototype database materials for an information network. The objects of information sources will be expanded to a nationwide scale in the future to improve the contents of the database. Problems of handling information copyrights and technical know-hows were presented in the course of data collection, urging the necessity of due considerations on the matter. Necessity was indicated on maintenance and management of data base as well as its quantitative expansion. 1 ref., 4 figs.

Various physiological reaction of plants would be obstructed and troubles of their growth would be met under environmental pollution. There are also cases that the polluted materials as nutritious components are absorbed by plants. Consequently, if plant's reaction on this environmental pollution would be used, indexes of environmental pollution and environment can be improved. For examples, Ipomoea Nil and Petunia having high reaction on photochemical oxidate are widely used as index plant of air pollution. Zelkova trees and poplars planted as street trees can also greatly absorbed the polluted gas and have a function to clear air. In this paper, a diagnosis method by visualizing plant's reaction on environmental pollution by using technique of image measurement was explained. As devices of usable image measurement, a thermal camera, a solid measuring cameras, an ultrasonic camera, a multi-spectral camera and an X-ray TV camera were given. 6 refs., 4 figs., 1 tab.

A verification was conducted on the micrometeorological function of paddy fields that control temperature conditions. A movement measurement was executed in order to elucidate air temperature distribution in the paddy field area. The observation revealed the following matters: air temperatures over paddy fields and farm lands are lower than those at bare lands and paved areas; air temperatures downwind the paddy fields are lower than those in residential areas; and air temperatures on the paddy fields are lower than those on the farm lands. Measurement of the air temperature distribution in paddy fields revealed that a paddy field becomes a heat absorbing source in the process of breeze blowing over the paddy field, and alleviates the temperature environment in the downwind area. A discussion was given on the specificity of surface temperature of the paddy field from the above result. It is the feature of paddy fields in summer that the energy exceeding the radiated amount is distributed into latent heat around the noon of a day. The surface temperatures are in the decreasing order of non-irrigated bare land > irrigated bare land > atmometer water surface > farm land > paddy field. The upper limit for the paddy field surface was around 28{degree}C. Surface temperature forming factors were discussed, and the surface temperature parameters (relative humidity, evaporation efficiency, etc.) were derived on each type of the land surface. The surface temperatures on each land surface were calculated using the parameter values. The result revealed that a paddy field having high relative humidity and evaporation efficiency has an effect to suppress the surface temperatures. 6 refs., 10 figs., 1 tab.

In recent European Union commissioned report, there was no evidence that the air raid of the NATO military in Yugoslavia became a cause of the large-scale ecology destruction until now. However, the pollution is very serious in industrial area suburb which becomes a target for Novi Sad and Pacncevo, Prahovo. The Hungary-based Regional Environment Center for Central and Eastern Europe in Hungary: REC was reported. According to REC, the pollution of the Danube river after the air raid which reaches for 11 weeks by the NATO military was serious, and ammonia of 100 tons, ethylene dichloride over the 1 thousand tons, 33% hydrochloric acid solution of the 1 thousand tons escaped to the Danube river from the air raid of Pancevo on April 18th. And, the mercury accumulated in sodium hydroxide of about 3 thousand tons, liquid chlorine of several decade tons and chlorine/alkali plant also escaped from Pancevo. United Nations-led Environmental Damage Assessment Mission should inspect Kosovo and Yugoslavia on July 19th, and it was announced with 'NATO does not show still us all well-informed information'. The investigation is carried out on the item which the Yugoslavia authorities designates, and the atmosphere level of VCM has reached 10600 times the concentration of the acceptable level near Pancevo, and it reports that acid rain was observed in each place.

This paper describes the removal technique of gases such as CO2, SO2 and NOx which have the deep relation to the maintenance of global environment. This paper describes partially r SO2 and NOx which are the primary cause of acid rain. As for the removal of CO2 generated from fixed sources (thermal power stations and others), the separation technique and isolation-fixation technique have been researched on and developed. Of the separation method, the effect of the chemical absorption method and the adsorption method is proved with the preceding experiments. The isolation method is differently researched on as to store under deep sea or ground but may be urgent and temporary. The fixation of CO2 is a serious global problem which relates to the afforestation and forests. The fixation which uses coral reefs in ocean as the absorption source has a potential. As for the processing of substances causing acid rain, the desulfurization from petroleum and the flue gas desulfurization have the excellent results. The improvement of combustion method or the flue gas denitrification at the fixed sources are used to remove NOx. The removal of NOx from all diesel cars is difficult compared with the exhaust gas cleaning of gasoline cars and is not commercialized. 11 refs., 1 fig., 2 tabs.

For the purpose of contributing to the promotion of methanol introduction and establishment of conversion technology, testing research on environmental safety of methanol was conducted, and the FY 1982 results were reported. In this fiscal year, construction was completed of testing facilities for breeding monkey/aquatic animal in the methanol environment, and test was started. In the test on the rapid exposure of macaca to high concentration (10,000ppm), effects were recognized on the blood physiochemistry, urine analysis, cardiac function, cerebral basal nuclei and cinerea part, as a result of various inspections/analyses made after 7-day exposure. Further, for the macaca exposed to a concentration of 3,000ppm, no remarkable changes were observed in urine analysis, pH value, etc. As to the effect of toxicity of methanol on oryzias latipes, toxicity is considerably lower than that of other chemicals. At about 3% concentration, half the number of oryzias latipes was fatal in 96 hours. Further, when diatom is exposed to methanol of concentration of 100ppm or more at the time of starting culture, the diatom continues to be hindered by methanol even after methanol fades away. At the same time, methanol also seems to have effects on the shape and metabolism of diatom. (NEDO)

The demonstration project is carried out in at Chaili coal mine in Shangdong Province, China for installation of and dissemination activities for circulating fluidized bed boilers to abate sulfur oxide emissions associated with utilization of coal, and the FY 1999 results are reported. The operating conditions were reviewed, and some recommendations were made for improving the operation procedures. Limestone was not used for desulfurization, and furnace temperature tended to increase due to increased size of the fluidizing particles. Therefore, it was recommended to use limestone at the design rate. The boiler was operated at a load exceeding the design level, and it was recommended to limit the load viewed from extending serviceability. The boiler start-up procedure was concretely proposed to use a mixed fuel of wood and coal instead of distillate oil, in order to reduce the start-up cost. The recommendations and design support activities for improving facilities included early stage repair of the damaged refractories. For build up of the ashes in the horizontal heat transfer section, the investigated design charts for improvement by installation of ash-discharging hopper were drawn and proposed. Maintenance-related information was given, including Chinese agencies for obtaining auxiliary facilities. (NEDO)

For the assessment of the environmental impact to be produced by geothermal exploration well boring and short-term outburst tests, water in hot spas, fountains, and rivers in and around the Appi survey district was inspected for fluctuation. A survey was conducted of multiple components to help analysis of the geothermal reservoir structure. Distributed in the alteration zone in this district are the hot spas of Kusanoyu, Shin-Kusanoyu, Appi, and so forth, and, in the vicinity, numerous hot spas including Iwahatanoyu belonging to the Appi hot spa. In the multiple component survey, 12 hot spas, 1 fountain, 8 rivers, and 2 gas wells were subjected to measurement. In the fluctuation survey, 5 hot spas, 1 fountain, 5 rivers, and the amount of precipitation were subjected to measurement. In the survey of river bottom quality and river bed rocks, river bottom quality was checked at 18 spots and river bed rocks at 12 spots. It was found that fluctuation was great in the amount of welling water at Kusanoyu, Shin-kusanoyu, and Appi, with the coefficient of fluctuation recording 10 or more. A negative correlation was detected between the welling amount and water temperature. It is deemed that the hot water spurts out of natural fountains or shallow wells and that its temperature tends to grow lower with an increase in meteoric water by which it is diluted. (NEDO)

A survey was conducted on 'what attractive research environment is for young researchers' as a theme. The young researchers are referred to as those who are registered on a master's or doctor's degree courses and what is called postdoctoral scholars who received a doctor's degree. In the survey, a few common comments were seen in over interviews on the U.S. research environment. The comments were such that, needless to say, subsidies are indispensable for researches but economic aspects of treatment are not necessarily satisfactory, that the research environment is generally good, allowing freedom in research, and that results tend to be achieved by providing a subsidy for experienced knowledgeable researchers rather than directly subsidizing young researchers with a large sum, while programs with individuality such as a fellowship are desired more. It is apparent that the interests of postdoctoral scholars are economic stability; in fact, uneasiness and dissatisfaction in the status and the treatment are pointed out in a survey by the U.S. Science Academy.

Explanations are given on the recent movements in the bio-technology applications. In the United States, gene therapy has been applied to patients having damaged immune system, while in Japan the first outdoor experiment is about to begin this year on gene recombined tomatoes. In the area of the marine bio-technology, researches carried out by the industrial, governmental, and academic sectors combined, led by the Ministry of International Trade and Industry have begun, which include such an attractive subject as finding out new kinds of algae living on carbon dioxide as their special favorite diet to use them to prevent the earth warming-up. On the other hand, the difficulty of bio-business is represented by the fact that venture business groups are absorbed into larger chemical companies. In Japan, the bio-business established in individual regions related to soy bean paste and Shoyu sauce industry is a distinct feature. Deregulations and review on the patent system are in progress in the United States and Germany aiming at strengthening the business competitiveness. Expectation is placed on the bio-technology that it will contribute largely in the future to solving such a critical environmental problem as experienced in the Persian Gulf war. 1 tab.

This paper introduces history of the development of an electric automobile, `Ecovehicle`. It is provided with a high overall energy efficiency compared with an engine vehicle. The Ecovihicle is 1.2m in width, 3.3m in length, 2 seating capacities and 910kg in overall weight with serially connected 56 batteries of each 4V, 40Ah and having the total weight of 269kg. Its travel distance per charging is 130km at a speed of 80 k.p.h. This vehicle is capable of running with an energy of approximately one third as much as that of a light car. In addition, the vehicle is provided with polycrystal solar batteries placed on 0.6m{sup 2} area on the roof and spoiler generating 60W maximum. Assuming the annual duration of sunshine is 1,800 hours, charging is possible for 63kWh annually. Assuming the charging efficiency is 83%, charging is possible about seven times, which is an equivalent of travelling about 1,000km annually. The characteristics for example are the employment of brushless DC motor, use of energy saving switching element IGBT in order to realize a low level of loss in the inverter, in-wheel motor system, and storage of storage batteries in a hollow aluminum frame installed under the floor. 2 refs., 5 figs., 1 tab.

In Japan, there were some serious disasters in recent years. In 1991, Unzen-Fugendake erupted and more than 1,000 people were forced to take refuge from their houses. In 1993, Hokkaido-Nanseioki earthquake attacked the south-east area of Hokkaido and more than 3,557 houses were destroyed. In Japan, the government supplies the temporary housing to those who lost house from the natural disasters. The purpose of supplying temporary houses mentioned in the disaster relief law (established in 1947) prescribes the purpose of temporary housing that to rescue the poor who can not afford getting a shelter with their own funds. But actual condition of temporary housing is completely different. Government supplies temporary housing to all those who request temporary housing. The term of using temporary house tend to become longer. The regulation about temporary housing has not been yet up to dated. Many problems concerning about temporary housing originate in outdated regulation. The temporary housing have to be ranked in the part of restoration process from natural disaster. (author)

Polychlorinated dibenzo-p-dioxins (PCDDs), polychlorinated dibenzofurans (PCDFs) and coplanar polychlorinated biphenyls (Co-PCBs) exhibit similar chemical and biological properties. Because of their highly toxic activity, the pollution with these compounds, which are called dioxin-related compounds, is one of the most serious environmental problems. In this review, we described the analytical methods of dioxin-related compounds in environmental samples, especially in the exhaust gas from the incineration site of municipal solid waste. In addition, we described the present situation of environmental pollution by dioxin-related compounds, including pollution levels in environmental, human, and food samples, daily intakes, and risk assessment. On the other hand, a number of microorganisms have been reported which are able to degrade dioxin-related compounds including PCDDs and PCDFs. These microorganisms are classified into two groups, lignin-degrading white rot fungi and the dioxin-degrading bacteria. We also described the degradation pathways of dioxin-related compounds in these microorganisms, and their degradative enzymes. 47 refs., 5 figs., 4 tabs.

In order to apply FEM (finite element method) flow analysis to environmental engineering, the two-dimensional analysis system was developed, and applied to the design of plant ventilation and improvement of an enviromental control equipment. Furthermore, the three-dimensional analysis system was developed to extend its application. Since in a large scale model, no enhancement of a processing capacity was expected even by a supercomputer because of longer I/O times between internal and external memories caused by a small internal memory space, the parallel processing system with multiple external memories was introduced to analyze such models. To achieve more efficient processing, multiple series of renumbering codes were also prepared to optimize the processing order of solvers, elements and nodes. As examples, the improvement of a thermal oxidizer and the ventilation design for a forging plant, and as an example of a three-dimensional large scale model, the flow analysis around a plant were presented. 8 refs., 17 figs., 1 tab.

Since the electric industry has grappled with a prevention of the environmental pollution such as the air pollution and water contamination as a forerunner in case of construction and operation of the power facilities, and at the same time has conducted actively the environmental conservation countermeasures, it has consequently achieved the environmental conservation level as a top level in the world. On the other hand, as for the emission quantity of CO2 relating to the earth warming, the power field occupies about one fourth of total Japan. Therefore the electric industry should aim at the electric energy supply considering the influence on the environment, such as the power supply structure to restrain CO2 emission as less as possible, higher efficiency of equipments, higher efficiency of energy utilization by using the unused energy and so forth. In addition to it, the consumer side should aim at the social structure with a recycle type such as saving resources and saving energy, and aim at changeover of life style. It is hoped to conduct the overall measure including the items mentioned above. In this report, the recent trend of earth enviromental problems, grappling with the environmental problems as a forerunner such as the prevention measure of air pollution in the thermal power plant, etc., and the correspondence to the earth warming problems are outlined. 11 refs., 9 figs., 3 tabs.

This report relates to the designing of functional materials that decompose in response to various signals. A derivative of {alpha}-bromomethylstyrene is caused to act on the living anions of {alpha}-methylstyrene for the synthesis of a pyrolytic polymer having unsaturated groups at its terminals. The terminal double combinations of this polymer split under the influence of heat, acid, or base for depolymerization which is quantative, and the decomposition temperature may be controlled by replacing terminal phenylallylic groups with methyl groups or phloro-groups. Furthermore, a novel polythyramine polymer is synthesized with its principal chain constituted of NCH2CH2Si, the principal chain easy to disintegrate when exposed to an electron beam. The polymer is signal-responsive and may be patterned by use of an electron beam. As a temperature-responsive polymer with the hydrolytic feature controlled, poly(thyroxy ethylene glycol) is obtained from a derivative of diaminosiloxane and oligo-oxyethylene. This is a high-mobility, temperature-responsive material whose hydrolysis may be controlled. 3 refs., 2 figs.

The effort aims to use low grade waste paper out of various grades of waste paper, whose recovery does not make good progress, as a raw material for the development of value-added, commercially competitive products and to contribute to the enhancement of waste paper recovery. A dry pulverization method less polluting the environment and not requiring a drying process is established, and types of waste paper and optimum conditions for their pulverization are made clear. A molding system using a steam injection method capable of atmospheric pressure control is established, and this enables the molding of pulverized waste paper not only into flat boards but also into corrugated boards. It is found that water contained in the waste paper alone produces a result similar to that expected from steam injection. A partitioning board is produced from waste paper, and it is found to be near the conventional product in terms of noise absorption. Old newspaper and corrugated cardboard are pulverized and an air filter is developed, which is similar to the conventional product in terms of operating efficiency and life. Waste paper is carbonized, and then charcoal with more pores than the conventional charcoal is produced. The porous charcoal is found to be usable in vegetable beds. (NEDO)

Survey was made of the case of applying the low grade coal reformation technology to commercial plants in Indonesia. In the survey, supposing the UBC process as reformation technology and 5,000 t/d as size of the commercial plant, studies were made of companies to be applied, schemes on the usable fund raising/governmental supporting policy, potential diffusion/effects of diffusion, facilities which can be domestically manufactured/subjects in promoting the domestic manufacture, economic F/S, etc. Different from the first generation coal companies, the second generation coal companies own low grade coal for the most part of the coal resource. Therefore, the companies are very much interested in the reformation technology. In the financial plan, the equipment cost of a commercial plant of this size was estimated at approximately 10 billion yen. This is a large initial investment for coal companies in Indonesia. So, it is necessary to consider a system of joint venture with Japanese users, etc. As to the study of the economical efficiency, the trial calculation indicated that the reformation cost was 7.35 US$/product ton and the price of reformed coal briquette product was 19.85 US$/product ton. In this case, ROI (return on investment) of 8.40%/year was expected. (NEDO)

To select projects of the New Sunshine Program which is the locomotive for Japan`s research and development of energy and environmental technologies and to map out the Program`s long-term strategy, it is required to develop an effective methodology of assessing research and development themes. It is also necessary to establish the pre-assessment system which makes the assessment process more logical and which will enable the priority setting among different themes on the basis of objective and quantitative analysis. Additionally, transparency should be ensured for such a pre-assessment process through disclosure to the public and other means. The present survey aims to concretize the pre-assessment system by studying the system and techniques of an assessment system which is applicable to the research and development themes of the New Sunshine Program and is objective, quantitative and logical and which can ensure transparency and by receiving suggestions on the pre-assessment of Japan`s research and development of energies and environmental technologies through research on overseas trends of government-led research and development. 3 refs., 7 figs., 26 tabs.

The R and D were conducted of a grinding machine system of an environmental-friendly type in which no coolant is used or the amount of coolant is reduced, and the FY 2000 results were summed up. As to the ECOLOG grinding newly thought up, the roles were divided: the lubrication into a trace of the vegetable oil supplied onto the grindstone surface, cooling into a trace of the cooling water supplied to the structure, discharge of chips to the cooling water for bed table cleaning. By this, the amount of the cooling water becomes approximately 1/3 of that in the conventional grinding. Concerning the ECOLOG grinding using the usual grindstone, the grinding performance equal to that in the conventional grinding was confirmed. In the study for making the cooling water non-pollutant, the chlorine/sulfur free coolant was developed which includes no chemical substances designated by the PRTR law at all. It was confirmed that the grinding performance was almost the same level as the existing coolant which includes sulfur. In the study of the supply of coolant applied with ultrasonic waves, the result was obtained that in the optical glass grinding, the number of scratches decreased and the surface roughness improved even at the flow rate of coolant which is less than in the conventional grinding.

Features of the continuing remediation involving corporations managed by AIG include the following: It has economical superiority; in-situ purification of contaminated soils is possible; and it can solve contamination issues in a short time, and makes reuse of lands possible. The remediation uses a principle of promoting the contamination purifying actions of the natural world. It activates microorganisms by supplying oxygen, water, and nutrients in suitable amounts for microbial activities to decompose chemical wastes and converts them into harmless substances such as CO2. Objects of purification include petroleum-based substances, herbicides, insecticides, and solvents. Establishing optimal parameters before purification (mediator variables and population parameters) and protocols is important. The system goes through the following steps: Hydraulic and geological experts identify patterns and levels of contamination; microorganism experts find optimal parameters in laboratories; engineers design treatment systems; and site technicians operate the system. 6 refs., 3 figs.

A method is developed of applying near infrared rays to the drying of paint coatings on resin-made automobile parts, and its environment improving effects are described. Using the conventional hot-air dryer for the drying of such coatings, the portion near the top surface is hardened prior to the other portions because the heat is absorbed near the top surface. Using an infrared drying system, however, defects in the product surface attributable to the lack of uniformity in the hardening of paint or to the splashing of solvent are remedied because deeper portions are hardened first. Experiment and study are conducted for the purpose of applying a near infrared drying method to an ABS (acrylonitrile butadiene styrene) coating. It is found that the near infrared drying method takes only seven minutes to dry a paint coating for which a hot-air furnace will take 20 minutes, thus shortening the drying time a great deal. Defects of gas hole of coatings are generally dealt with by changing the setting time and drying conditions for example by increasing the amount of the diluting thinner. When an near infrared drying method is used, the amount of the diluting thinner is reduced approximately 50% from the amount required using the hot-air drying method in case of the thickness of 60{mu}m. 2 refs., 9 figs., 2 tabs.

For the state-run plant of Pakistan Steel in Pakistan, an investigational study was conducted on energy conservation and reduction in greenhouse effect gas emission. In the project, energy conservation technology on the following was tried to be introduced: coke oven coal moisture control (CMC) equipment, sintering cooler waste heat recovery equipment, blast furnace hot stove waste heat recovery equipment, blast furnace pulverized coal injection (PCI) equipment, blast furnace top pressure recovery turbine (TRT) equipment, and hot strip mill heating furnace regenerative type burner equipment. Further, in the project on environmental improvement, studies were made on coke oven environmental improvement and blast furnace cast house dust collection. The results of the study indicated that economical effects of the energy conservation project were considered as low because the unit price of energy of Pakistan Steel is low. However, substitution of the low-priced domestic coal for the imported coal has a good effect, and energy conservation in the TRT power generation and by the regenerative type burner produces a highly economical effect. Therefore, Pakistan Steel also agrees to positively promote the project. Moreover, concerning the environmental improvement project, it was considered that the necessity of the project is high in the relation of the coke oven aimed at reducing emissions of toxic substances.

To verify the clean coal technology to be diffused in China and consolidate its diffusion basis, demonstration project of circulating fluidized bed boiler was conducted through the cooperation with China which is positive in its introduction. This report describes its characteristics. Coal and limestone are supplied in a lower part of combustion chamber, and are mixed with circulating ash by fluidized air for combustion. Densely fluidized bed the same as the bubbling fluidized bed is formed in the lower part of combustion chamber, which provides excellent stability in ignition and combustion. Particles including ash, char and limestone formed during the combustion are discharged into the cyclone through the convection heat transfer part at the outlet of combustion chamber with the combustion gas flow. Since the gas temperature is lowered to 400 to 500degC at the convection heat transfer part, troubles of the ash circulating system can be prevented. The combustion gas separated from ash at the cyclone is discharged through the heat exchanger and precipitator, and the collected ash is returned to the lower part of combustion chamber. In FY 1997, design, fabrication, procurement/inspection, field survey/meeting, survey of visitors/meeting, and education were carried out. 4 figs., 4 tabs.

The effect of lemon, jasmine and lavender aroma on people was studied through environmental aroma experiments by 270 subjects in a meeting room for two months. As a result, the high percentage of positive responses was obtained on the sense of air cleanliness and efficiency of meetings, and a statistical significance was, in particular, obtained in the case of lemon as smoking was permitted. It was suggested that aroma had physiological and phychological effect even under conditions where the subjects were not necessarily aware of aroma. The effect of the same three aromas was also studied through experiments by 13 subjects in a VDT room for one month. As a result, the number of keypunch errors decreased in every aroma although punching speeds decreased slightly, and lemon showed a significant difference among three aromas. Based on these experimental results, the aroma generator was developed, and more than 30 environmental aroma systems combined with air conditioning ducts have been installed in Japan. 20 refs., 5 figs., 6 tabs.

An investigational study was conducted on energy recovery (power generation) in disposal of industrial waste. The capacity of power generation facilities in incineration processing of industrial waste reached approximately 200,000kW (50 facilities) in the total nationwide. The incineration-processed waste is mainly chips of wood, waste tire and bagasse. Almost all the electric power is for non-utility use, and there are no examples of selling it outside. In the metropolitan area, there is only one example of the industrial waste incineration power generation in Tochigi prefecture. This is because there are extremely very few enterprises which are sources producing the waste as target. However, if the industrial waste market is targeted, there is a future. The industrial waste has a lot of disadvantages as power generation use fuel because of its diversification, but the use of it as fuel is technically easier than the use of the general waste as RDF. Accordingly, it can be used for power generation with no need of special technology or facilities. When picking up facilities with a potentiality of high efficiency power generation from the existing incinerators in operation of persons in charge of industrial waste processing, approximately 125,000 kW can be obtained only from remodeling of the existing facilities.

In Vietnam, survey was conducted of the project in which the adoption of circulating fluidized bed boiler (CFB) makes energy conservation and greenhouse effect gas reduction possible. CFB makes a marked decrease in SOx emission possible by using limestone as combustion bed material. As a result of the survey, the thermal power plant was not suitable for the model project due to its large size. However, it was found that two cement plants and one fiber plant having coal-fired boiler were suitable for survey. Nghi Son and Bim Son cement plants are typical cement plants in Vietnam. As a result of the hearing, they were eager to adopt CFB equipment. As to environmental improvement effects, in the thermal power plant with power source loads, emissions of SOx and NOx can be reduced by 79.0% and 72.5%, respectively. Further, in Nam Dinh Textile Company, emissions of SOx and NOx can be reduced by 79.8% and 84.6%, respectively, in case of converting boiler from the existing stoker boiler to CFB boiler. (NEDO)

This paper reports the surveys in fiscal 1999 on energy and developmental problems in Japan and the U.S.A. New and complex environmental problems are rising to the surface, such as global warming, ozone layer destruction, and chemical harms. It is necessary to deepen quickly scientific understanding of the problems, and identify accurately their impacts on human bodies and ecological systems. Within the limitation of the scientific understanding, political decisions on economy and environmental risks are also important and difficult questions, with the environmental hormones being the typical examples. Establishing chemical substance verification systems is important, whereas joint researches by Japan and the U.S.A. are desired. Policy decisions on handling the researches must also be made jointly, and acceptance by citizens must be asked for at international workshops. While energies are the base of economic activities, and the sustained development thereof is indispensable, how to take balance with health and environment in the global scale is a large assignment. Joint Japan-U.S. discussions are required on technological innovation, such as for regenerative energies, energy conservation, safety of and wastes from nuclear reactors, clean use of fossil fuels, and fuel cells. International cooperation, including that from developing countries, is also important. (NEDO)

The members of MHD project examination subcommittee made an investigative tour of the U.S. on the state of development of MHD generation. This report of the 2nd part explains opinions and the present status of the R and D on MHD generation by each of the 19 institutions visited. The U.S. research on MHD generation is under the leadership of DOE, whereby the budget for the development is so large as nearly one hundred million dollars have been provided for several years. The purpose is the effective use of domestic coal. General Electric is of the opinion that a combined gas turbine system will be put to practical use earlier because MHD takes time for practicability despite its highest efficiency in coal-utilized power generation. Yet, GE thinks MHD will be more attractive in the future. Reynolds Metal is considering application of MHD generation to the electro-chemical industry at present. According to Reynolds, combined supply of electric output and heat of MHD can reduce the use of calorie per ton of aluminum from 240 MBTU to 100. Montana Power is promoting practicability through a combined plan with DOE-built MHD generation. (NEDO)

The paper investigated and studied the present situation and future trend of coal utilization and distribution in Thailand, and the present situation of environmental effects and the measures taken for environmental protection. Around 2010, coal will probably be produced only at EGAT`s Mae Moh (MM) coal mine. Demand for overseas coal is expected to be 40-50 million tons in 2011, and preparation of the coal center becomes a subject. For general industry use coal, pretreatment such as coal preparation, coal blending and briquetting is needed, considering coal quality, usage, transport distance and environmental effects. Brown coal of MM coal mine is a lignite with high sulfur, high ash content and low heating value. Wide spread of its use can be expected if upgrading is possible such as desulfurization, deashing, increasing heating value. In the electric power generation field, the absorber was installed at the existing boiler of the mine-mouth generating plant to conduct a verification test on high grade desulfurization of ultra-high sulfur lignite. In the industry field, the circulating fluidized bed boiler was adopted. In the residential/commercial field, introduction of briquette was proposed. 80 refs., 84 tabs.

Learning from a history of the earth of ancient times, the paper studies effects of refreshing environment and soil or making them natural and harmless mostly using primitive bacteria, and develops element technology which is industrially accelerating. The spread type accelerator working only by solar energy was installed and operated for experiment. As indices of refreshment effects, a study was comparatively made between a sugar degree of sweet potato and a yield shown in the number of potatotimesunit weight. An EM propagation garbage layer is formed, and the two sections were installed of a site of the actual installation of the spread type accelerator and a site naturally left alone. Other effects of weather, temperature and humidity which are external factors and general fertilization are offset as common modes, and a consideration was so made that only refreshment effects of primitive bacteria can be relatively compared. Acceleration effects in using accelerator for growing sweet potato could be quantitatively confirmed. As to sugar degree, because the last study was made in the beginning of summer, the underground temperature was high enough. Even only EM effects were fully effective. This time, the weather was much colder, and it was found to be a must to use accelerator. 2 figs.

The relationship between environmental control and biotechnology is discussed, and purification of moats and lakes is taken up as a concrete example of introducing biological waste water treatment technology to ecotechnology. In addition, an overall waste disposal system connecting cities and agricultural districts is investigated. After the purification of water and waste problem solution, etc. are discussed, the importance of creating ecopolis and ecotown is described. The 3 concepts of microbial ecotechnology (high densification of organism, field control, interaction between organisms) are used to explain biological treatment technology. Attempts for direct purification and ecotechnology are described quoting a few examples. If waste produced in cities and ligneous materials or charcoal obtained from forests are mixed for treatment, effective waste treatment or new resources production may be possible. It seems to be possible to create ideal ecopolis and ecotown by applying the doctrine of irrigation, drainage and reclamation engineering and the technology established by now. 35 refs., 1 fig., 2 tabs.

This paper describes use technologies of organic materials for selecting them under various environmental conditions. FRP is superior in mechanical strength and chemical resistance, and suitable as anticorrosion structural materials. Its chemical resistance is dependent on matrix resins. Simple polyolefine system resin is superior in chemical resistance and cost, however, because of its poor mechanical strength, it is mainly used for small parts. The composite structure is used for middle tanks or piping materials where the inside surface contacting solution is lined with chemical resistant resins such as PP and PVC, while the outside surface is reinforced with FRP. Various lining materials and lining methods are used. The following materials are used for lining: liquid resin type one such as tar epoxy resin, melting powder type one such as PE, PP and fluororesin, laminated glass fiber type one using cold setting polyester and thermosetting phenol resin, compound type one of scale-like glass flake and resin, and rubber or plastic sheet material. It is important to select optimum material for lining. 1 fig., 2 tabs.

This paper summarizes the following techniques: a gene engineering method for bioremediation and wastewater treatment, microorganism breeding using the former method, and a monitoring technique for genetical and ecological stability of genetically engineered microorganisms. Recombination bacteria reinforced with PH genes showed higher phenol removing rate than wild strains, but presented accumulation of catechol in such a large quantity as cannot be seen in wild strains, with the complete degradation rate rather decreased. Gene recombined bacteria structured by introducing the recombined plasmid, pBH500, had high genetic stability when P.putida BH-1 is used as a host. E.coli C600 having recombined plasmid and P.putida BH were added and cultivated in activated sludge. As a result, both recombined bacteria showed rapid logarithmic decrease just after the addition, then, maintained the relatively stable population groups, and remained in the activated sludge for an extended period of time. In monitoring techniques, the colony hybridization process detected clearly the gene recombined bacteria. 9 refs., 7 figs., 1 tab.

Atmospheric concentration of CO2 is increasing, and discussions are urged on measures to suppress emission of CO2 into atmosphere. While different CO2 fixing technologies may be conceived, there is a technology to utilize CO2 absorbing capability of ocean by discharging and dissolving CO2 artificially into middle layer of the ocean to separate CO2 from atmosphere. This technology is one of the technologies which are promising in the aspects of technology, economic performance, and possible amount of CO2 reduction. However, it is difficult to say that scientific and technological discussions have been given sufficiently on behavior of CO2 discharged into the ocean, effect of the discharge on environments, and CO2 separation capability of the ocean. Therefore, in the present research and development, a 'technology to forecast environmental effect in areas in the vicinity of CO2 discharging points' is developed to serve for acquiring technological prospect on the feasibility to realize the CO2 ocean separation by discharging CO2 into the middle layer of the ocean. The present fiscal year has performed researches on the following research and development items: elucidation of behavior of liquefied CO2 when discharged into the ocean, CO2 feeding and diluting technologies, indoor experiments on the effects of CO2 on ocean living organisms, and development of a model to forecast environments in areas in the vicinity of CO2 discharging points.

An investigational study was conducted of applicability/viability of the technology to recycle as resource the organic waste and CO2 discharged from the chemical industry, etc., and the FY 1999 results were summarized. As to the production of hydrogen from the organic waste, a bioreactor was developed which enables the production of hydrogen of 58 mmol/L/hr using Enterobactor aerogenes by the isolation bacteria method, and it successfully enabled the production of hydrogen from biomass resource. Further, the micro-flora method can be responded to a variety of substrates, but in this method the hydrogen production rate is not as high as in the isolation bacteria method at the present time. Concerning the method to convert CO2 to useful organic resource by the hydrogen produced, an experimental value of the maximum production rate of 149g/L/d which is high was obtained in case of acetic acid. Moreover, the paper described an outline and the basic concept of the recycle system of energy and carbon resource which integrates the production of energy from organic waste being considered at the present time and the production of useful matters from CO2.

A potential study in FY 1998 was made of the energy/environment related activity implementation joint (COP3 related AIJ) in 6 Southeast Asian countries. Vietnam is a country which is the lowest in greenhouse effect gas (GHG) emission in the world, but they want the international assistance for their continued development and contribution to the global environment. Laos has to continue their economic development for extermination of poverty and improvement of life level. Accordingly, AIJ has to be the one that supports those and is helpful for both industrial development and environmental improvement. The same in Cambodia as in Laos, AIJ has to be the one that is helpful for both industrial development and promotion of environmental improvement. In Myanmar, GHG emits (CO2 conversion) 94.5% in the agricultural sector where methane is emitted from livestock and rice growing. There, the forest protection plays a big role. In Thailand, the use of land and forest protection are subjects mainly with the heightening of energy efficiency and fuel substitution. Malaysia, of course, promotes the economic development, has the leading GHG policy (traffic management in urban area, etc.), and wants the international technology transfer. (NEDO)

The paper surveyed the present situation and future trend of economy, energy supply/demand, coal production/distribution/utilization and the environmental effects in Thailand. The survey on the coal utilization and its environmental effects was partially requested of the environmental research institute in Thailand. The amount of coal utilization in Thailand rapidly increased to nearly four times as large as that ten years ago mainly in terms of domestic lignite under the government`s policy on expansion of the domestic energy use. However, most of this domestic lignite is low-grade coal with low calories and high sulfur content, and the use of it was rapidly increased mostly in power generation sector without no adequate environmental measures taken. This caused an environmental problem on air pollution due to sulfur oxides at Mae Moh power plant in the north several years ago, and the damages to the regional residents, etc. were given much publicity by journalism and developed the social problem. Accordingly, Thai people are now critical of the coal resource exploration and the coal use expansion. Under the circumstances, the Ministry of Industry and the energy related ministries/offices are obliged to review their development/promotion plans. 84 figs., 99 tabs.

Grasping the present situation of coal utilization technology in the Philippines, the paper proposed a feasibility study of introduction of the environmentally friendly type coal utilization system which seems to be needed in the future. (1) Introduction of the environmentally friendly type coal utilization system in the electric power generation sector: there are only four full-scale running coal thermal power plants in the Philippines. In the future, several coal thermal plants are planned to be constructed by 2005, but for the new installation, it is desirable to adopt fluidized bed boilers with wide application to coal kinds. In case of 0.3-1.0 million MW class plants, it is planned to adopt high grade import coals, and it will be natural to fire pulverized coal. For the processing of flue gas, it is a must to install desulfurization facilities and smoke/soot removal devices. (2) Utilization/development of domestic low grade coals: at the mine-mouth generating plant, it is necessary to investigate the economically minable amount of coal, confirm productivity, survey coal quality, etc., and select boiler. As to coal briquetting technology, it is necessary to examine coal quality for tests and make a thorough study of what technology is most suitable. 50 figs., 78 tabs.

The aim is to develop a technology for detecting environmental pollution before it becomes apparent and thereby to contribute to the development of technologies to minimize the damage that may be inflicted upon the global environment. For this purpose, researches are conducted in search of techniques to detect, at high speed with high sensitivity over a wide scope, the response of living organisms to chemicals. In a research on the application of the reaction of ecosystem to environmental stress, communication between living organisms in coping with environmental chemicals is investigated. It is then found that the growth of vegetable roots may be used as a measure for the detection of environmental pollutants but that the method is too low in sensitivity. A research is conducted on the creation of an ecological reporter function using the biological amplification technique. It is then found that the immunoreaction-aided measuring of environmental pollutants yields an excellent result in terms of sensitivity but that it has a problem in its resistance to environmental conditions. In a research on the standardization of environmental measurements using ecological information, it is found that the primary object of research and development should be a systematization technology compatible with biological functions.

Researches were conducted with a view to organizing projects for developing intelligent fibers, equipped with environmental friendliness and amenity without being deprived of their original properties as structural and clothing materials, the ultimate goal of the effort being the creation of harbingers of next-generation fibers which would contribute to the advance of industries related to environments, medicine and welfare, and information. What were learned from fiscal 1998 researches are mentioned below. The strength that the general-purpose fibers currently in use exhibit is so small as to be but several percent of what is theoretically predicted for them. Demand will increase a great deal if the actual strength is doubled, for which new technologies have to be developed including those involving super-fiber texture control. For providing the fiber with such functions as environment-friendliness, amenity, etc., it is necessary to develop phasal structure control technologies with regard to fiber morphology, surface texture, etc. For success in practical application in the future of such super-fiber materials, each specimen needs to be manufactured in the order of kilogram by way of trial. Moreover, fiber evaluation techniques have to be developed in the three domains of software, hardware, and interface. (NEDO)

Recently, environmental pollution by a large amount of undecomposable waste has became a serious problem. Therefore, biodegradable polymers, which can be degraded by environmental species such as bacteria and enzymes, have been studied extensively. Most of the biodegradable polymers prepared so far were polyester derivatives such as poly(hydroxybutyrate/valerate), poly(lactide) and poly(glycolide). The degradation mechanism is the hydrolysis of the ester groups in the main chain of the polymer which is facilitated by enzyme degradation. Most of the mass-produced polymers, however, are vinyl-polymerized plastics such as poly(ethylene), poly(propylene) and poly(styrene). There is no technology on the degradation of such vinyl polymers except in the lithography field, in which it is known that some vinyl polymers can be used for posi-type resists by decomposition with UV or electron-beam (EB). For creation of degradable polymers, the following three factors must be considered Purpose of the project seriously; 1) What degrades the polymers? 2) Row long does the polymer maintain the initial properties? (Time course of the mechanical strength, etc.) and 3) Bioactivity of the liberated oligomers. The aim of our work is the creation of new polymers which can be easily controlled by the above three factors. If we can degrade the polymers from the end of the polymer chain, i) we can control several properties of the polymers in the degradation such as degradation source (pH, light,, UV, EB, etc.) and rate of the degradation by changing the structure of the end group; 2) production of oligomers, which may induce a significant problem in terms of bioactivity, can be suppressed because of the depolymerization from the end of the polymers (only the monomer will be liberated). In this project, we investigated to synthesize the end functionalizations of poly({alpha}-methylstyrene) derivatives and their degradation characteristics using temperature, acid and alkaline conditions. To induce degradabilities in polymers in response to environmental conditions, the end-modification reactions of poly({alpha}-methylstyrene) (PMS) derivatives were carried out. When diphenylphosphine chloride was used as a modifier for the living end of para-substituted PMS, the coupling efficiency was ca. 50%. 2-Phenylallyl halide derivatives such as 2-phenylallyl bromide, 2-(4-tolyl)allyl bromide, and {alpha}-trifluoromethylstyrene were found to be suitable end-modification agents. For example, {omega}-2-phenylallyl PMS was prepared with almost quantitative functionality by the reaction of the living PMS with 2-phenylallyl bromide. In a similar way, {omega}-3, 3-difluoro-2-phenylallyl and {omega}-2-(4-tolyl)allyl PMS derivatives were synthesized. Based on thermogravimetric analysis, onset of the degradation temperature of the end-modified PMS derivatives decreased in the following order: {omega}-hydrogen- > {omega}-3,3-difluoro-2-phenylallyl- > {omega}-2-phenylallyl- > {omega}-2-(4-tolyl)allyl-PMS. Actually, the onset temperature of {omega}-2-(4-tolyl)allyl-PMS derivatives was 50 degree C lower than that of {omega}-H-PMS derivatives. These results indicate that the active species is produced effectively at the end unsaturated bond, which initiates the depolymerization of the polymer at rather low temperatures. Ionic degradation of these polymers was also investigated using butyllithium as an anionic initiator and methanesulfonic acid as a cationic initiator Tendencies similar to the thermal degradation were observed. Therefore, it is concluded that a 2-phenylallyl substituent at the end of the PMS chain induces effective degradation through several mechanisms such as radical, anionic and cationic depolymerization reactions.

In promoting international collaboration research project, coordination of the patent system of each country which participants to the project belong to has broad implications in concluding the contract for the project. For example, in Japan, 100% of the patent belongs to the government for contrast or collaboration project with the government. While, in the USA, the patent developed by the private company belongs to the private company even for the contrast project. In Japan, the shared patent can not be transferred to the third party or implemented without agreement with the partner. While, in the USA, the shared patent can be transferred to the third party or implemented without agreement with the partner. Due to such a difference, some projects can not be established by ill coordination of intellectual property even when the meaning of the projects is well understood. In this survey, was investigated the outline of patent systems of major countries to study about what should well balanced treatment of intellectual property in international collaboration research project be in the future. 4 figs., 8 tabs.

This survey arranged the status of coal utilization technology and the status of coal production, supply, etc. in Malaysia and Vietnam, examined/studied coal utilization systems in both countries, and finally assessed feasibility of introducing the environmentally friendly type coal utilization system. As a country of primary energy source which is abundant in crude oil, natural gas, hydroelectric power, coal, etc., Malaysia now depends on crude oil and natural gas for 80% of its energy, and places emphasis on exploration of natural gas and oil refining. In electric power and cement industries where coal is consumed, effectiveness and environmental issues in association with coal utilization are future subjects. In Vietnam, the north is abundant in hydroelectric power and anthracite, and the south in oil and gas resource, but the north and central districts are in a state of undevelopment. Coal is used for coal thermal power generation, cement industry, and residential/commercial fuel. In the future, effective coal utilization and environmental issues will be subjects. 16 refs., 38 figs., 75 tabs.

The aim is to develop a technology for detecting environmental pollution before it becomes apparent and thereby to contribute to the development of technologies to minimize the damage that may be inflicted upon the global environment. For this purpose, researches are conducted in search of techniques to detect, at high speed with high sensitivity over a wide scope, the response of living organisms to chemicals. In a research on the application of the reaction of ecosystem to environmental stress, communication between living organisms in coping with environmental chemicals is investigated. It is then found that the growth of vegetable roots may be used as a measure for the detection of environmental pollutants but that the method is too low in sensitivity. A research is conducted on the creation of an ecological reporter function using the biological amplification technique. It is then found that the immunoreaction-aided measuring of environmental pollutants yields an excellent result in terms of sensitivity but that it has a problem in its resistance to environmental conditions. In a research on the standardization of environmental measurements using ecological information, it is found that the primary object of research and development should be a systematization technology compatible with biological functions.

For the construction of houses that effectively utilize natural energy and impose less load on environments, an example of house building respecting environmental symbiosis is described. Reported herein are a heating system and the measurements of thermal environment in winter. In winter, the floor is heated by warm water from solar heat collectors circulating in pipes buried in downstair underfloor RC foundation. For the verification of the heating effect, comparison was made between the heater-provided southeast (SE) room and heater-unprovided northeast (NE) room, both downstairs. Warm water circulated in the underfloor pipes only in the daytime, the pipe surface recording the maximum of 32{degree}C in the daytime and the minimum of 17{degree}C early in the morning. At midnight, the SE room was warmer than the NE room by 2{degree}C. The slab surface in the SE room recorded 28{degree}C at the maximum and 17{degree}C at the minimum, but the temperature remained constant at 10{degree}C in the NE room. The rubble temperature was 17.5-20{degree}C in the SE room and approximately 11{degree}C in the NE room. It was noted that the SE room floor slab was capable of heat accumulation. The resident is a devotee of environmental symbiosis with mindset for enhancing natural energy utilization, burning an oil heater and a fireplace but intermittently. 1 ref., 12 figs., 1 tab.

For the purpose of corresponding to changes of the industrial structure and making full use of the control technology, the paper investigated the state of the application. High-grade automation in the manufacturing industry has reached the spread of use at big companies for these 10 years. The hierarchical structure of business/process/DCS has been completed, and the optimal control and the advanced control have been realized. The development and spread to the much wider field is anticipated. The soft structure system is needed for equipment improvement in view of the life cycle of equipment and toward the elimination of bottlenecking. For the design of the control system, commercial tools began to be much used, and it is expected in future to accumulate and recycle the knowledge/knowhow for effective design work. Further, strict simulation models based material balance and heat balance have also been on the rise, and the advance in technology is expected. Because of the total productivity of the production equipment, the control technology is anticipated not only for the pursuit of controllability but for the use as supporting technology in the operation/driving/failure diagnosis for working out, carrying out and evaluating the optimum operation plan. 18 refs., 99 figs., 100 tabs.

This paper describes a report on the material committee for coal gasification technology development in fiscal 1988. The in-plant test on new materials has performed information investigation on use characteristics and use records of new materials. A sulfurizing corrosion resistance test showed that the aluminum-chromium diffused and permeated material and the molten aluminum plated material stabilize the coated surface and have high corrosion resistance. Ceramics painted lining material was evaluated unusable in a steam diffusion test. Phenol resin was found sufficiently usable as a result of giving the stress test at 100 to 150 degrees C. In developing a let-down valve, a high-velocity water slurry injection test revealed that CVD coating of Ti (C, N) has high effect of suppressing the erosion damage. In a high-velocity powder injection test, PVD coating of TiN and CVD coating of TiC were found to show good erosion resistance. Tests and researches were performed to evaluate durability of furnace materials for manufacturing gasified hydrogen, and elucidate conditions to cause iron oxide burst. Evaluation on repairing techniques, and improvement on durability were also executed. (NEDO)

This report describes the impact assessment which is an important step for LCA. For classification of the impact assessment, the existing literature was reviewed and a skeleton for the classification was proposed. The weighting factors for nine selected impact categories, which were used to calculate environmental load point (ELP) for the valuation, were obtained for two overseas groups, i.e., students of Amsterdam University and SETAC Europe members. It was found that the former provided the similar trends to general Japanese, however that the latter gave high weighting in the global warming and depletion of ozone layer. The ELP was proposed and applied to automatic washing machine, coffee maker, waste incineration power generation system, and co-generation system. As a result, its effectiveness was demonstrated. This report also describes problems for the LCA of thermal and material recycling of PS trays. 99 refs., 96 figs., 73 tabs.

In an effort to extend cooperation for reducing pollution in urban areas in the Asia-Pacific Region, a laser radar system was constructed in the city of Djakarta, Indonesia, in 1996, and a follow-up started in fiscal 1997. The aim is to collect information necessary for atmospheric environment improvement through observing pollutant distribution and movement in the upper atmospheric layers over the city. Mie-scattering lidar (laser infrared radar) observation has uninterruptedly been on since the summer of 1997, the system collecting data about Djakarta's atmospheric boundary structure throughout the year. The data indicate great changes in the atmospheric boundary structure between the dry and rainy seasons. The result of intensified observation conducted in the dry season shows that the altitude that the mixed layer reaches in the inland region is higher in the daytime and lower in the nighttime. It is necessary to compare the result with atmospheric pollution data collected on the ground surface and determine the relationship between the behavior of pollutants and the circulation of land-and-sea breeze. The data of September, 1997, reveal an aerosol layer at altitudes of 2km and higher, and this is attributed to forest fires. The result of intensified observation conducted in the dry season of 1998 is also stated. (NEDO)

This paper describes a survey on problems in developing technologies for the global environment issues. Technological development of means to reduce generation of environmental issues and substitutive means for non-generation thereof is being moved forward specifically in the Sunshine Project and the Moonlight Project. The Chemical Technology Research Institute assumes that it has a responsibility to positively contribute to developing a technological system that matches the substance circulation mechanism of the earth from the fields of chemistry. Therefore, the Institute has organized working groups that have been identifying problems from their expertise standpoints and have been extracting study assignments. Subsequent to the Version I, the Version II has been compiled. The Version II takes up the simulation of global warming mechanisms, behavior of gases dissolved in oceans, and possibility of fixing CO2 in oceans. With respect to fluorocarbons, the Version II describes development of substitutive substances, their stability, combustion method as a destruction technique, and destruction by means of super criticality. Regarding CO2, the version introduces technologies to re-use CO2 as a resource by means of membrane separation, storage, and contact hydrogenation. The volume also dwells on CO2 reduction by using photo-chemical and electrochemical reactions, CO2 reduction and photo-synthesis by using semiconductors as photo catalysts and electrodes. (NEDO)

Techniques have been studied to accelerate, on a commercial scale, the natural refreshment effects which synthesize useful materials, such as compost and grape and amino acids from carbon dioxide, oxidized wastes and excretions exhausted by man. The symbiotic relationship between primeval bacteria and useful bacteria for Japanese traditional foods was investigated in 3 different experimental sections which were commonly composted; the first one consisting of composted soil, the second one provided with a layer (EM layer), in which these bacteria were densely cultured, on composted soil, and the third one with a common accelerator driven only by solar energy. A total of 9 seed potatoes were planted, 3 for each section, to monitor their growth. It is quantitatively confirmed that, when cultured in the third section, they grow roughly 3 times faster than in the first one. Sweetness can be sufficiently secured by the EM effect, because of sufficiently high ground temperature in early summer and an anaerobic atmosphere kept in the system. 6 refs., 2 figs.

Research was made on electronic NEDO research reports corresponding to the recent extending trend of Internet. The logical structure and electronic format of NEDO research reports as document were first studied considering document disclosure and reuse of technical information. HTML as electronic format for Internet is unfortunately insufficient to describe the logical structure of NEDO research reports because of HTML's restricted description. Thus, XML which is being watched because of its possible definition of original tags was studied in place of HTML. As a result, because at present preparation of standards on XML and a compatibility for implementation of standards are insufficient, it was concluded that construction of the electronic document system for NEDO research reports is still too early. However, since adoption of XML as document format is important from the viewpoint of a property succession on Internet, preparation of the XML format file of NEDO research reports is essential.

For the purpose of working out a comprehensive master plan for application of the coal utilization system, the paper surveyed and studied the coal utilization system in terms of environmental measures and efficiency improvement in the utilization of coal. As a result of the discussion with NEDO and the National Planning Committee of China, Liaoning Province (the whole China) and Shenyang City were selected as a model area and a model city for the survey and study. As energy conservation measures taken in the former, desirable are intensifying/capacity-increase of boilers, kilns, etc. and adoption of new-type/high-efficient equipment. Also expected are reinforcement of combustion control and improvement of efficiency by using coal preparation, industrial use coal briquette, etc. Measures taken in the latter are the same as those taken in the whole China. As SOx reduction measures for Liaoning Province, desirable is installation of dry-type desulfurization equipment and simple desulfurization equipment. As dust prevention measures for it, desirable is installation of electrostatic precipitators or high-functional bag filters. SOx reduction measures for Shenyang City are the same as those taken in the whole China. SOx can be reduced by using coal-prepared low-sulfur coal and industrial use coal briquette added with desulfurizing agent. 88 figs., 163 tabs.

For the purpose of spreading/promoting circulating fluidized bed boilers in China, survey was conducted on the confirmation of effectiveness of implementation of the model project on spread type circulating fluidized bed boilers and the appropriateness of the sites proposed for implementation. As to the model of spread type 35t/h-CFB boilers, local products are more integrated into it, taking cost reduction of equipment and secure performance/quality into consideration, and the wider-ranging technical guidance/transfer are conducted also in design/production. In China, where environmental regulations are not strict, and there are many restrictions on funds, the size of the initial investment is an important element for selection of type. Further, the market is very big, about 200 units/year. It is highly possible to realize the competitive cost level by the quantity production effect by increasing local production. Two companies, Southeast Electrochemical Co. and Fujian Prime Pharmaceutical Group Co., which were proposed as sites are financially good and are achieving substantial results. Both companies are located in the urban area, and therefore, environmental measures should urgently be taken, and PR activities for spread are highly effective. It was confirmed that the companies were fully appropriate as sites proposed for the spread type model project. (NEDO)

In the survey, the following were studied: regional characteristics of the said area, levels of technology of direct combustion/thermochemical conversion, future technical trends, system candidate, grasp/analysis of the resource amount, characteristics of ligneous biomass resource in the said area, analysis of economical efficiency of the procurement of biomass resource, grasp of energy users, etc. As a result, a system was selected of a 1,000kW scale cogeneration of ligneous resource. At the present technology level and under scale conditions, it was found out that the fixed bed direct combustion system was the most profitable in securing the economical realization. As to the system mostly for power generation, however, it was found out that the heat low in unit price of energy production should widely be used because the installation cost of plant is comparatively high. Facilities such as Kochi Medical Center where heat is in great demand throughout the year can expect profit from selling heat, and therefore, those have high potentiality of the commercialization.

Surveys and discussions have been performed in Yuge Town in Ehime Prefecture for aiming at promotion of district development and zero emission in islands by carbonizing general wastes (household refuses and business operation wastes) and bamboos in the islands to utilize their energies as a substitute for the heat source of the warm sea water bathing facilities, as well as utilizing the produced carbides as soil improving materials or deodorants. The surveys were performed on bamboo carbonizing and gas carbonizing technologies, energy utilization feasibility, analysis of wastes composition, and identification of quantity of bamboos in existence. In discussing the energy utilization system by means of carbonization, it was revealed that the introduction of the bamboo carbonizing and gas carbonizing technologies can sufficiently satisfy the heat demand of the Yuge Town community facilities, although the amount of heat that can be supplied may vary because of difference in the technical processes. Also with regard to the problems of dioxins contained in the discharged gas and the problems of heavy metals contained in the carbides, it was discovered that different environmental criteria can be met as evidenced by the existing demonstration data.

This paper reports the activities of the coal type committee in fiscal 1992, and summarizes the main technological achievements. In the Chinese coal liquefaction test, fiscal 1991 has performed liquefaction tests on Fushun coal by using a small continuous testing facility (0.1 t/d) at the Coal Chemistry Research Institute in Beijing. Fiscal 1992 has completed the liquefaction tests on Shengli coal. In October, a liquefaction test was carried out by using Tianzhu coal according to the NEDOL process. This paper reports the result of the liquefaction test on the Shengli coal, and the result of the analysis on the Fushun coal liquefied oil. The coal type selection and investigation having been performed to date reveals close correlation among the maceral composition of coal, coal rank and liquefied oil yield. Coals having good reactivity and suitable for liquefaction are generally suitable also for gasification. In the pretreatment of coal as a gasification material for hydrogen manufacture, a test was performed by using A heavy oil and tar sand bitumen plus A heavy oil as the granulating agents. With Montana coal, the highest de-ashing rate was achieved when the oil was added at 35% by weight. Both of the reaction rate and oil yield were improved. A handling test was carried out up to 72.5 degrees C, wherein Tatung coal presented no problems in both of the discharging and sticking tendencies. (NEDO)

A coal type research project is started under which data concerning the coal resources that Japan can make use of are to be gathered, which are necessary for determining their fitness-for-use in a coal liquefaction or gasification process, and the gathered data are to be compiled into files which are easy to use. As for the buildup of a computer-aided data bank, since the number of coal types is not yet large, only part of the data is taken into consideration this fiscal year. In the study of compiling the data into files, it is decided that the files be divided into two categories, one for grasping the status of the development project as a whole and the other for defining the positions of the individual coal specimens. Provided in the former are outlines covering the name of coal mine or project, location, entrepreneur, states of the mining area and geology, state of production, infrastructure-related matters, etc. Described in the latter are the details that enable the identification of given specimens such as the coal bed or coal brand, location and method of collection, collector, date, amount of the specimen, method of treatment, etc. (NEDO)

An epidemiological survey survey was performed to elucidate the fungal flora of a dwelling house. The measurements were carried out in an apartment in Yokohama from Jul. 1996 to Dec. 1997. Fungi were isolated from 106 sampling points (the surface of the walls, floors, etc.) with sterile stamps. It was proved that Cladsporium, Penicillium, Eurotium, and Yeasts showed characteristic distribution. Especially Cladsporium was not isolated from the spring to the summer, but increased in the autumn. In addition to the survey, experiments on fungal growth temperature (13, 20, 25, 30, 36, 42 degree C) and water activity (A w 0.75{approx}0.97) were carried out. Cladsporium grew well in 13, 20, 25 and 30 degree C, but didn't grow in 36 and 42 degree C. In addition, the growth activity of Cladsporium was down below Aw 0.91. Eurotium was isolated from under Tatami, where it has an unchanging temperature and relative humidity. Yeasts preferred very high humidity. It was concluded that environmental factors such as temperature and relative humidity related to the growth of fungi. (author)

To investigate the energy demand and supply structure in Japan, the international trend of approaches to global warming problems and the mitigation options to global warming in the energy related sectors have been surveyed. For the United Nations Framework Convention on Climate Change, an Ad-hoc Group has discussed relevant topics after the 1st conference of the Parties. Meetings of the Group primarily focused on what objectives to set for the reduction of greenhouse gas (GHG) emissions in and in and after 2000. IPCC completed their Technical Paper in November 1996 in which technologies and measures to reduce GHG emissions and to enhance GHG sinks were analyzed and evaluated in various aspects. This Paper discusses about each sector of institutional buildings sector, transport sector, industrial sector, and energy supply sector. Especially, in the energy supply sector, promising approaches to reduce future emission include more efficient conversion of fossil fuels, switching to low-carbon fossil fuels, decarbonization of flue gas and fuels, CO2 storage, switching to nuclear energy, and switching to renewable sources of energy. 5 refs., 2 figs., 14 tabs.

Corrosivity of vapor-phase aenvironments in indoor pool, water thank, and water purification plants was investigated. Sodium hypochlorite (NaClO) was used as a sterilizing agent in indoor pool, while chlorine gas was used in water tank and water purification plants. It was found that Cl{sup -} ion were concentrated in the dew formed in the indoor pool. H{sup +} ions as well as Cl{sup -} ions were accumulated in the dew dormed in the water tank ans water purification plants. Thus, the corrosion condition was varied with the type of sterilizing agents used. Through the investigation of water tanl, the relationship between pH and Cl{sup -} ion concentration was given as follow; pH=-1.09-2.19 log [Cl{sup -}] (mol/L). Corrosivity of vapor-phase enviroments in sterilizing water systems would be characterized by the exstence of oxidizing chemical agents such as ClO{sup -} and HClO, the shift of corrosion potenrial of the thin water film, and the accumulation of H{sup +} and/or Cl{sup -} ions in the dew.

The world energy demand is increasing with the development of the world economy and the improvement of the life level. In view of the future economic development and population growth, the world energy demand will considerably increase especially in the LDCs. Since the oil crisis, saving of energy and material were effectively executed, thus significantly reducing the energy requirement per GNP. However, in the recent several years, the conciousness of energy has become diluted, causing considerable consumption in larger size and higher grade products, thus increasing the non-industrial and transportation consumption. This report considered the effective use of energy and the nuclear application. It is to be noted that the accident frequency in the Japanese nuclear plants is much less than the other countries. The coal utilization requires further technical development in view of the environmental problems. Other substitutible energies are all weak in competition and cannot be expected utilizable in large scale for the time being. This report also referred to the oil problem. 9 figs.

This paper summarizes application of photo-catalysts in environmental problems. The paper lists examples of the application in residential environments. Photo-catalytic decomposition is possible by using ultraviolet rays contained in room illumination if the bacterial presence is sparse. The examples thereof may be cited as follows: if colon bacilli are suspended on a tile with TiO2 photo-catalyst sintered in it and exposed to room illumination, the bacteria are disinfected; using photo-catalysts in a bathroom suppresses deposition of Pseudomonas aeruginosa; a photo-catalyst tile (TiO2 loaded with Cu) and light irradiation reduce intensity of tobacco smoke odor; and adsorbents may be used simultaneously if intermediate products are odor generating substances. The examples of applying photo-catalysts to regional environments may be quoted as follows: growth of algae in a Petri dish is suppressed by presence of Cu loaded TiO2 under room illumination; this leads to an expectation on its effect in a relatively clean water environment; glass beads loaded with a TiO2 photo-catalyst placed in a gold fish breeding tank reduces turbidity, the number of colon bacilluses, and COD value; and the mortality in gold fish shows no change. With an objective of application to exterior building materials, photo-catalyst applied tiles were left outdoors for 160 days. Nitric acid ions were detected that are thought to have been generated by decomposition of microorganisms that have deposited on the tiles. 6 refs., 5 figs., 3 tabs.

In a servo PD (positive displacement) flowmeter for oil, a differential pressure transmitter detects difference in pressure between the PD flowmeter input and output ports and a rotor is driven by a servo motor so that the pressure difference between before and after the PD flowmeter rotor will be zero. The design enables high-accuracy measurement across a wide range of flow rates and is not easily affected by the surrounding physical conditions such as viscosity and density. For the development of such a flowmeter, it is necessary to develop a rotor that rotates smoothly free of locking in a steady and uniform flow, to build a visualized model that enables the analysis of flow inside the flowmeter which in turn will enable the determination of optimum differential pressure detecting ports, and to connect a newly developed servo mechanism to the thus determined ports. As the result of the research, a servo PD flowmeter is developed, which is a 50mm diameter prototype employing the Invoflex tooth form which is the waveform for a rotor suitable for a high performance flowmeter. Placed in a generally used oil flow calibration liquid, which is gasoline, kerosene, or the like, it covers a flow rate range of 1:10 and reads with an accuracy of {+-}0.1%. It remains stable in performance and suffers but a little change with the passage of time. (NEDO)

A high speed towed type physical and chemical observation marine robot named as `Flying Fish` has been developed since 1992, which can measure chemical substances in the sea as well as physical data, such as flow velocity of the ocean and water temperature. This paper describes its formation, designing, control system, and results of ocean tests. For the space continuous observation of physical, chemical, and biological quantities, it is essential to control the depth, pitch, and roll. The wing control method was employed for this robot. As a result of the ocean tests, the following conclusions were obtained. The accuracy under the steady state was {plus_minus}0.05 m in the depth, {plus_minus}1 degree in the pitch, and {plus_minus}0.5 degree in the roll. This was stable enough to operate chemical analysis, such as dissolved oxygen analysis. Even under the unsteady state during the change of depth, the pitch and roll were controlled in {plus_minus}3 degree and {plus_minus}0.5 degree, respectively. Results of the field tests and the numerical simulations for the performance of this robot were agreed well mutually in the practically sufficient accuracy. 10 refs., 15 figs., 2 tabs.

The present paper suggests chief measures to suppress and reduce global greenhouse gases. Under the control of artificial environments such as bioreactor, hydroponics and vegetable factory, a very high fixing rate of CO2 can be obtained, but CO2 generation accompanying electric power consumption is also large. It is preferable to use methane as resource by reforming reactions or selective oxidative reaction. In the recovery technique of fluorocarbon, 100% recovery is desirable. Techniques for decomposing recovered fluorocarbon and converting it to harmless material are the most backward ones. Understanding of essential structural relationship of coal is necessary for establishing combustion technique for the reduction of N2O. The integrated power generation system composed from solid electrolyte type fuel cell and coal-gasifying process, high-performance, superheat pump system form scientific technology imposing no burden on the global environment. Establishment of purification technique for industrial- or living-related drain inflowing to a closed water area system, establishment and reinforcement of inspection system for oil spill in the oceans in a global scale are required. 240 refs., 63 figs., 30 tabs.

In order to structure a chemical reaction process that does not discharge a large amount of waste by-products or harmful chemical substances, or so-called environment friendly process, investigations and discussions were given based on the results derived in the previous fiscal year. A proposal was made to reduce environmental load on development of oxidized and dehydrogenated catalysts that can produce selectively ethylene, propylene and isobutylene in an oxidation process. In liquid phase oxidation, redox-based oxidation and solid catalyzation of automatic oxidation reaction were enumerated. In acid base catalyst reaction, development of ultra strong solid acid was described to structure no pollution discharging process. In the fine chemical and pharmaceutical fields, the optical active substance method and the position-selective aromatics displacement reaction were evaluated to reduce environmental load. A questionnaire survey performed on major chemical corporations inside and outside the country revealed the following processes as the ones that can cause hidden environmental problems: processes discharging large amount of wastes, processes treating dangerous materials, and processes consuming large amount of energy. Development of catalysts is important that can realize high yield, high selectivity and reactions under mild conditions as a future environment harmonizing chemical process. 117 refs., 23 figs., 22 tabs.

The fatigue behavior of ceramics has been discussed on the basis of the relation between stress intensity facter (KI) and crack velocity (V). In this paper, the effect of environment on the relation between KI and V was studied on machinable ceramics (mica glass ceramics) and two kinds of glass ceramics with different grain sizes. The double torsion (DT) technique was used for the determination of the KI-V characteristics under different environments of air and ion-exchanged water. The characteristics of acoustic emission (AE) during stress corrosion cracking of mica glass ceramics was also examined. In water environment, the region II in the KI-V curve, in which crack velocity varies slowly with KI, disappeared. From this experimental fact, it was considered that at high KI, the crack velocity is encouraged by diffusion of the corrosive species to the crack and thus depended on the amount of water. SEM farc tography revealed that mica single crystals in the material caused crack arrest and deflection to occur. It is also found that AE event rate is quantitatively related to the crack velocity. AE measurement can be used in studying the crack propagation behavior of mica glass ceramics. 11 refs., 12 figs., 3 tabs.

With an objective for spatial continuous measurement of physical, chemical and biological amounts in ocean, development has been made on a wing controlled towed vehicle, `Flying Fish` which is capable of controlling depth, pitch and roll. Numerical simulations and two-year sea experiments have been carried out for the development. Flying Fish consists of a sub-system comprising a towing vehicle, towing cables, and on-board controllers. In a steady state, Flying Fish can be controlled at accuracy for depth of {plus_minus} 0.05m, pitch of {plus_minus} one degree, and roll of {plus_minus} 0.5 degree. This accuracy is sufficient for operating a chemical analyzer, the dissolved carbonic acid analyzer. Even in a non-steady state such as in changing the depth, the pitch can be controlled at {plus_minus} 3 degrees and the roll at {plus_minus} 0.5 degree. This extent of attitude change is within a range rendering no problems in maintaining accuracy of the measurement devices. The result of sea experiments for movements of Flying Fish agreed with that of the numerical simulation at practically usable accuracy. Flying Fish is verified as an effective system in investigating spatial variations in ocean data. 10 refs., 15 figs., 1 tab.

Energy conservation is considered the most realistic measure against the problem of the global warming for the time being. Developing countries consume about 30% of the energy consumed in the world. Although their absolute consumption amount is little at the moment, their energy consumption is increasing year after year. Efficiency of their energy utilization is low because compared with advanced countries their equipments are of old type and their technologies are behind the times. It is, therefore, estimated possible to conserve energy by 30% with e improvements and plant and equipment investments. It is very effective to introduce Japanese advanced energy conservation technologies to these countries through international cooperation. In fact investigation commissions composed of experts have been dispatched to Thailand, China and Argentine, experts have been dispatched to foreign countries to stay there for several years and give assistance, trainees have been received, and study and training meetings have been held already. Seminars with Japanese lecturers have been also held in many foreign countries since 1983. As for the future prospect, establishment of core organizations as the base of technologies and human resources in foreign countries for the further promotion of assistance is expected. 7 figs.

Summarized in this report is the material already distributed concerning the program for modifying the Nakoso 200t/d pilot plant entrained bed coal gasification furnace. The program aims to verify the overall suitability for power generation use of the air-blow pressurized 2-chamber 2-stage flow entrained bed gasification furnace. Although each specific feature of gasification furnace performance is found to be satisfactory, yet a 100% operation and extended continuous operation remain to be accomplished. Slagging is a phenomenon of ash grains in high-temperature gas adhering to and growing on the furnace walls to block up the furnace to eventually disable the furnace from continuous operation. In view of past achievements and test results, it is found that slagging is closely related to the behavior of floating or molten ash and to the transition temperature range. Various slagging measures have been taken for the current gasification furnace, but they prove to be ineffective. Some drastic measures need to be implemented for improvement. Under study using model furnaces and test furnaces are the reduction of slag generation at its source (re-entrained slag), prevention of adhesion (untrapped slag), removal of slag, optimization of gyration in the furnace, modification of slag properties for enhanced discharge, optimization of the transition gas temperature range, and the modification of furnace dimensions.

This paper reports a joint meeting of the coal liquefaction committee and the coal type committee in fiscal 1993. The report is focussed on the coal type selection (the final report) for the coal used in the 150-t/d coal liquefaction pilot plant (PP) among other agenda. Initially the Australian Wandoan coal was scheduled to be selected as the reference coal for the PP operation, but the mine has not gone into operation, hence the schedule was given up. Screening was carried out to select a coal which is commercially produced and exported, and contains ash at 10% by weight or less, sulfur at 1.5% by weight or less, and chlorine at 300 ppm or less. An autoclave and a 0.01-t/d flowing type device were used to evaluate liquefaction performance, whereas the Tanito Harum coal produced in Indonesia, very similar to the Wandoan coal, was selected as a promising candidate. A PSU was used to demonstrate overall operation performance. The coal is an appropriate reference coal as seen from the aspects of liquefied oil yield, nature, operability, and site surveys in Indonesia. Among the actual record of four kinds of PSU coals in the past, the present coal has the oil yield ranked high, has the least liquefaction residues, and is advantageous economically. The oil yield per ton of coal has cleared the PP target of four barrels. The coal has less ash, is easy in solid/liquid separation in the depressurized distillation, and has no problems in operability, excepting the matter of coal supply. (NEDO)

This is a summary primarily of the distributed material. As of December 14, 1995, the 200t/d pilot plant for power generation by entrained bed coal gasification records a total coal gasification operation time of 4,485 hours with an accumulated amount of power generation of 9,227MWh. A large combustor is tested, and it is found that combustion is stable under a 1/4 load with low NOx emissions. The combustor is sufficiently cooled with a small supply of air. Coal ash and coal, supplied in a constant state for an improved heat recovery efficiency in the development of hydrogen-from-coal technology, are heated to a temperature near their melting points. They are then allowed to impinge at a heat transfer plane simulating a gasifier heat recovery section, and a study is made of the mechanism of ash adhesion, molten or semi-molten, to the heat recovery section. The reduction of the heat transfer coefficient due to added grains is 30-50%, and the reduction is small when the heat transfer pipe surface velocity is high or when the carbon concentration in the grains is high. In another effort, utilization of coal-derived gas as town gas is studied. As for yields as indicated by the Curie gas pyrolyzer, the gas yield increases and liquid yield decreases when the reaction temperature is high. Using a small test unit, it is found that a rise in the hydrogen partial pressure increases the production of both gas and liquid. (NEDO)

Summarized herein are results of the studies on closed cycle MHD (CCMHD) power generation by the study committee. The studied system is based on the MHD gas turbine combined Brayton cycle of about 500,000 kW in output power, firing natural gas as the fuel, and the conceptual design works therefor are completed. The major findings are: the overall plant efficiency: 54.2% at the power transmission side, plot area required per unit power output: 0.04 m{sup 2}/KW, unit construction cost: 251,000 yen/KW, and unit power generation cost: 10.2 yen/KWh. This system will be more operable than the gas turbine combined cycle with steam system, because start-up time, output change rate, optimum load and so on are constrained not on the power generator side but on the gas turbine side. The expected environmental effects include the exhaust gas NOX concentration being equivalent with that associated with the conventional power generator of 2-stage combustion system, quantity of combustion gases to be treated being approximately 40% of that associated with the gas turbine combined cycle, and reduced CO2 gas emissions, resulting from enhanced power generation efficiency. It is expected that the CCMHD system can exhibit higher efficiency than the high-temperature gas turbine combined cycle system. (NEDO)

A business feasibility survey was performed on introduction of an RDF electric power generation system utilizing general wastes in the Noto area. Wastes quantity was estimated by accounting for large-sized wastes to be generated newly as a result of enforcement of the container package recycling law, and transfer of non-combustible wastes to incineration. The quantity was estimated to be 84,000 tons annually. Quantities of RDF and heat were calculated from this estimation to be 103 tons per day and 400 lkcal/kg respectively. According to the result of discussing the RDF transportation systems, time-based freight was found advantageous for short distance, and distance freight system for long distance in terms of cost. Discussions for RDF power systems were carried out on an RDF circulation fluid bed furnace plus ash melting furnace, a fluid bed gasification melting furnace, and shaft furnace type gasification melting furnace. In a comprehensive view, it is difficult to distinguish them in terms of merit and demerit. Molten slag was assumed to be re-utilized, but cost for the re-utilization should be considered. According to the result of discussing the business feasibility, it was found difficult to make it profitable by operating the RDF power generation business alone, and wastes incineration charge should be collected.

Research and development was conducted of a technology for manufacturing an ultrathin polycrystalline silicon solar cell capable of efficiency enhancement and cost reduction earlier than the types of polycrystalline solar cells now available on the market. In this fiscal year, a silicon melt/solidification experimenting apparatus was built for manufacturing high-quality silicon ingots. Using an apparatus with its performance similar to the newly built one, a preliminary experiment was conducted involving high-purity silicon ingot manufacturing. In the experiment, boron was added to 75 kg of silicon for semiconductor devices so that its resistivity may be 0.5 ohm-cm. The silicon was melted in a quartz mold, and then subjected to unidirectional coagulation at 0.13 mm/min that started at the bottom to proceed upward. The result was a silicon ingot 44 cm times 44 cm times 17 cm (height). The ingot thus obtained exhibited 0.4-0.8 ohm-cm in resistivity distribution. Solar cells produced from the ingot showed a conversion rate of 16.9%. (NEDO)

This paper is a survey report for fiscal 1999 on structuring of the circulation type economic society harmonizing with environment. In order for Japan in the 21st century to solve various problems while maintaining sustainable development of the industries and economy, structuring the industrial technology strategies is indispensable. In order to establish targets to structure the circulation type society harmonizing with environment, small targets were broken down and specific technological examples were extracted as seen from categories based on flows of goods and the policy aspects. Then, from the viewpoints of extrication from wastes, reduction of risks caused by harmful substances, and growth under suppression of the global warming, case studies were performed on policy aspects toward the year 2010. Based on these studies, images of the emphasizing strategies were prepared, that are built on three pillars of 'R', the reduction, reuse and recycling. Specific technological examples were extracted comprehensively and specifically from research and development themes in research institutions inside and outside Japan to prepare a fundamental material for establishing the small targets. Furthermore, the examples were classified from the aspects of the three Rs. Areas of technological development seeds and areas with fewer seeds were made clear successfully. (NEDO)

Devices that decompose halogen compounds by use of AlPO{sub 4} are built, and studies are made concerning the collection of basic knowledge and findings, the settlement of problems that accompany scaleup, and the elucidation of mechanism of catalytic function occurrence. Tests are conducted at an intermediate plant, when catalytic performance is observed using a unit accommodating 1 liter of catalyst and chlorofluorocarbon (CFC) 12 is subjected to decomposition for the selection of proper operating conditions. Results similar to those from micro-reactor operation are attained when the reaction tube temperature is controlled. On the basis of the results, a real reactor and reaction system are designed and constructed, and CFC12 containing some CFC115 and CFC22 is made to undergo a decomposition reaction in this real reactor. It is then clarified that CFC catalytic decomposition proceeds at a low cost without generating dioxins and that therefore the process is commercially viable. In the study of catalytic adjustment, it is found that adjustment may be sufficiently effected when baking is conducted at 1,000 degrees C even when the extrusion process which demands low manufacturing cost is employed. Studies are also conducted about the mechanism of co-catalytic function occurrence. (NEDO)

In the manufacturing process of semiconductors and in the high tech industry, cleaning is indispensable. At present, when regulation of the use of CFC which used to be much used has been decided on, the conversion to the use of substitutes for CFC cleaning is urgently needed. Transfer to cleaning by water/alcohol/hydrocarbon has been proceeded with, but there are a lot of problems. Out of the development of the cleaning method using supercritical fluid, the paper described the fiscal 1997 result. As to enhancement of efficiency and decrease in size of equipment, a cleaning experiment by high pressure CO2 around the critical point was conducted by integrating nozzle, ultrasonic generator and cavitation generator and adding solvent circulating system. Multi-purpose and energy saving of the equipment were also studied. To establish an analysis method for the cleaning degree, the contaminated component film of trace organic matter with a specified thickness was formed on the silicon wafer, and using the Fourier transform ultrared spectroscopy, a method to determine the film thickness was studied. For the function evaluation for precision machine parts and determination of optimum cleaning conditions, the cleaning/degreasing process of valves were compared with the conventional method. For the product manufacturing, the paper investigated and prepared the data in Japan and from abroad. 55 refs., 79 figs., 18 tabs.

This survey was made to obtain the basic data for future spread and promotion of No.6 type (waste use type production facilities) and No.7 type (waste fuel production facilities) which were added to the objects having been subsidized since fiscal 1997 under `the environmental harmony type energy community project.` In the former, the kiln in the cement industry and the blast furnace in the steel industry can be extremely large places to receive waste plastic since the facilities are distributed in every area and the treatment capacity is large. However, the effective collection, transportation and sorting of large quantity of waste plastic, especially the problem of removal of vinyl chloride, is a big bottleneck. As to the use of waste plastic using gasification technology, there are no actual results on the commercial basis. That is, however, appropriate for treatment of the waste difficult in treatment, and can be expected of the usage in the chemical industry. In the latter, in the facilities using industrial waste raw materials as fuel, solidification and liquefaction are both operated on a commercial basis. In relation to the solidification and use as fuel of general waste, the treatment of combustion ash is preventing the expansion of use of waste in the industrial field because of a large quantity of chlorine included in the products. 92 refs., 54 figs., 35 tabs.

In order to construct real sustainable global environment and human society in the 21st century called the century of environment, not only the innovation of manufacturing processes technically supporting such the construction but also the conception including the innovation of the whole society from a wide viewpoint are essential. As a total energy and material control system (TEMCOS) concept, the view of an energy-saving circulating society is attempted which minimizes a total energy and material flow in Japan, and the role and issue of manufacturing industry, in particular, material industry are extracted. As one of the targets of such a concept, the conception of an eco-town is also described. Paying attention on some important material industries including a mass material flow and consuming a large amount of energy such as metal, plastics and automobile industries, the study result on a material flow for every industry is arranged, and some effective issues contributing to minimize a material flow and control energy consumption and CO2 emission are extracted. 80 refs., 67 figs., 30 tabs.

For the purpose of studying an expanse and characteristics of the geothermal system and a possibility of geothermal development in the Haneyama area, Oita Prefecture, geochemical survey was conducted. In the survey, various kinds of analyses were made for 13 specimens of hot spring water and 5 specimens of surface water in the area of about 280km{sup 2} at 402 measuring points of the concentration of Hg in soil gas. The results of the survey were as follows: In this survey area, it was thought that the HCO{sub 3} type geothermal water of a comparatively low temperature which was heated by the wide-spread conduction heat from the depths was widely distributed deeper than the depth of 500-700m, and it was presumed that a possibility was low of existence of a high geothermal potential which can be used for the geothermal power generation in the part deeper than the drilling depth of 700m. In the Noya area in the southwest part of the survey area, the high temperature deep geothermal reservoir was confirmed. In this area, the high temperature neutral-alkalescent Cl-SO{sub 4} type geothermal water was distributed in the depth of several 100 meters or deeper. The geothermal water seemed to flow from NE to SW along the structure in the NE-SW direction, and it was concluded that the area was the most promising one. (NEDO)

Study was made on promotion of CDM (clean development mechanism) project through technology transfer with plant exports. Although CDM system was provided in COP3 on climate change held in Kyoto in 1997, its detailed rules including project approval are yet undecided, and only the schedule to provide the detailed rules until COP6 in 2000 was decided in COP4 in 1998. The common recognition that the CDM project with plant exports produces various merits for both Japan and the partner country is increasing. However, from the viewpoint of forming concrete CDM projects, most Japanese enterprises are passive in approach to the CDM project because of no detailed design of CDM, uncertain profitability and procedures, and avoidance of additional burdens. Plant export is also difficult because of the fact that assessment of a new project is difficult. Enterprises' deeper recognition on the CDM project, and a governmental integrated support system are desirable. (NEDO)

For the contribution to elucidation of the geothermal structure in the Haneyama area in Oita Prefecture, gravity prospecting was conducted. Survey was carried out in the area of about 280km{sup 2} at 205 measuring points, and analysis was made altogether with the existing 3,273 gravity measuring points. As a result, the following were made clear. The gravity basement forms the fault-state structure that sinks several 100 meters to the south side on the line from the south edge of the Higashi-shiiya ridge to Mt. Kurotake - Mt. Daigansen - Amagase hot spring in the SW direction. This fault was made correspondent to the Beppu north fault on the east side of Mt. Kurodake. Each of the following regions is the region where the fault-state structure that predicts the development of fracture and the area of distribution of alteration zone that can be cap rock overlap each other: NW edge of Shishimuta sedimentation zone - Machida alteration zone distribution area; N edge of the Shishimuta sedimentation zone - Ibushi alteration zone/Noya alteration zone distribution area; Vicinity of Mt. Kurodake - Hijiu alteration zone distribution area. It seems that the above-mentioned regions have high potentiality of geothermal exploration. The region where new igneous activities are seen, which is near the heat source, is important for exploration. The distribution area is seen near the west of the Mizuwake Pass ridge. (NEDO)

To know the trend of measures taken for global warming, conducted were overseas surveys, participation in academic society meetings, and literature surveys. The phaseout time of all ozone depleting substances responsible for the ozonospherial destruction was determined for both developed and developing countries in the 7th Meeting of countries which concluded the Montreal Protocol. As information on measures for protecting the ozonosphere, introduced was activities under United Nations Environment Programme (UNEP). New fluorine containing ethers were introduced as cleaning solvent which causes no ozonospherial destruction and is low in global warming index. Toxicity data were obtained on HFC-236ea and HFC-236fa which are promising substitutes in HCFC foaming and refrigerant fields. The paper introduced an outline of the 1st Meeting of countries which concluded the Framework Convention on Climate Change held in 1995. According to the report on the National Institute of Public Health and Environmental Protection of the Netherlands, the amount of emission of fluorine containing greenhouse effect gas (in CO2 conversion) reached 8-14% of all the amount of greenhouse effect gas emitted in 1990 unless the control is reinforced. An outline of the TEWI-3 project was introduced which is useful for comparing effects of substitution technologies on global warming. 14 refs., 11 figs., 29 tabs.

Because of an increase in energy demand due to economic growth and industrial structure change in the Asian area and its effect on global environment, the economic evolution harmonizing with energy and environment (3E) of the Asian area is required. The role of Japan, in particular, NEDO for achieving such 3E was studied from an international viewpoint. The following are thus surveyed: The history of energy demands, economic growth, an increase in energy consumption and their effect on global environment in the Asian area, and the policies, measures and future plans of Asian countries corresponding to the above situations. The role of NEDO is first of all R & D of biomass toward practical use, and development of effective use technology of biomass energy. Positive approach to control of CO2 emission and immobilization of CO2 is also required in industrial and traffic fields. As technology transfer from Japan, promotion of joint researches and establishment of an economic support scheme are expected together with transfer of the basement technology and training. 79 figs., 13 tabs.

Evaluations were given on spatial resolution and measurement time of an optical tomographic system by using the developed 64-channel time-resolved spectroscopy and an image reconstruction algorithm. With respect to the spatial resolution, the target value of 1 cm was verified from tomographic images of a phantom with a diameter of 10cm, simulating a neonate. The measurement time achieved 20 minutes, being one third of the target value. In installing the equipment at Hokkaido University, speeds of the optical switches and attenuators were increased to have reduced the measurement time to one minute. For installation at Kanagawa Rehabilitation Center, development has been made on a nano-second light pulser, whose average beam quantity has been increased to 40 times, and improvement has been given on the optical switches, the attenuators, and the indication software, by which the measurement time was decreased further by 30 seconds than that at Hokkaido University. In performing the clinical evaluation, the evaluation protocol resolved by the Experiment Evaluation Special Committee was submitted for deliberation at the Medical Welfare Device Clinical Evaluation Committee. Upon having been authorized by the Committee, the clinical evaluations were performed at Hokkaido University and the Kanagawa Rehabilitation Center. (NEDO)

Arrangement, investigation and analysis of an energy information exchange system were conducted, with the aim of coping with the development in the whole Asia/Pacific area, the stabilization of energy supply/demand, and the environmental problem and of realizing effective cooperation of every country in the area. Concerning the trend of the domestic primary energy supply/demand, there are some patterns. Countries which show high growth rates are developing countries such as Thailand and China, and NIES such as Korea and Taiwan. Countries where growth rates are slowing down and lowering are developed countries such as Australia, Canada, Japan and the U.S. Countries where energy supply/demand is not stabilized are Singapore, Hong Kong, Indonesia and Chile which are suffering from variations in import/export. The ultimate energy consumption is the domestic primary energy supply from which the conversion loss in the conversion sector was deducted, and indicates almost the same trend as the primary energy supply. It is divided into a stabilized type of developed countries and a rapidly increasing type and a stagnant type. However, there are some exceptions. Total data in the quarter of the year cannot be the yearly data by itself, but requires a year-end tax arrangement. 40 tabs.

The ability that architectural space improves the thermal environment in comparison with outdoor environment is called the `capability of controlling thermal environment.` As the value becomes higher, the indoor thermal environment is more improved. In this paper, the controlling capability of six building envelopes with different window systems was compared. The heat transfer in the wall and window system is approximated using a lumped mass model of heat capacity to obtain a heat balance equation and combined with the heat balance equation in indoor air for backward difference. The wall surface temperature and indoor air temperature in a calculation model are then calculated. A radiation absorption coefficient is used for mutual radiation on each wall. In the model, the adjoining room or first- and second-floor rooms were made the same in conditions as the model on the assumption that the one-side lighted office in an RC reference floor is in the non-illumination and non-airconditioning state. In summer, the controlling capability remarkably varies depending on the window system. For the window facing the south, the annual capability is more advanced than in other directions and the indoor thermal environment is improved on the average. 7 refs., 12 figs., 1 tab.

A rough design was performed on a floating airport. On this floating structure, environmental external force was estimated, mooring design was carried out, and discussions was given on the position retaining performance important for airport functions and behavior of the floating structure. The discussion was given on cases that the airport is surrounded and not surrounded by floating breakwaters. A floating structure which becomes super-large in size requires considerations on force due to sea level gradient as a result of a tide. Deriving flow condition changes and force acting on the floating structure simultaneously by using numerical calculations makes it possible to estimate current force given with considerations on influence of the flow conditions created by installing the floating airport. Estimation was carried out by using a zone dividing method on wave drifting force acting upon the floating airport. As a result, it was found that installing floating and permeating type breakwaters can reduce the wave drifting force acting on the floating airport. The wave drifting force working on the floating airport can be reduced by installing the floating and permeating type breakwaters to lower levels than when no such breakwaters are installed. The airport may be moored with less number of fenders when the fenders of the same type are used. 18 refs., 10 figs., 5 tabs.

For the purpose of studying how the energy supply/demand structure in Japan should be, a report on the secondary IPCC (Intergovernmental Panel on Climate Change) evaluation was analyzed. Possibilities of reducing the world CO2 emissions in association with the energy consumption were studied in the five assumed cases. Every case says that CO2 can be reduced to 1/3 of the 1990 level by 2100. In a case of the use of biomass as main fuel (1), the use of primary energy is suppressed to two times the 1990 level, and photovoltaic/wind/biomass power generation is introduced in a large quantity. Synthetic methanol and hydrogen are used for transportation and commercial/residential use fuels. There are four more assumed cases: the use of nuclear power as a substitute for renewable energy in the power generation in (1), the use of natural gas of 1.5 times that used in (1), the substitution of coal for biomass used in (1), and the assumption that the demand for primary energy in 2100 will be twice that used in (1). In Japan it is assumed that basically the nuclear power generation will be expanded, that the photovoltaic and waste power generation will be introduced in a large quantity, and that synthetic methanol and hydrogen are mainly used as transportation and commercial/residential use fuels. It is necessary, therefore, to analyze conditions under which the quantity introduction of such non-fossil energy is made possible. 11 figs., 31 tabs.

For the contribution to elucidation of the geothermal structure in the Wasabizawa area, Akita Prefecture, survey by the paleomagnetic measurement and fracture system measurement was conducted of the borehole cores and specimens of outcrop granite obtained from boreholes of N6-WZ-3 and N6-WZ-4. In the survey, the following were carried out: measurement of the core fracture system of N6-WZ-3 (102-1,505m) and N6-WZ-4 (507-1,556m), paleomagnetic measurement of 9 outcrop granite specimens and 16 core specimens, and k/Ar age determination of 3 outcrop granite specimens. As a result of the paleomagnetic measurement of outcrop granite, the magnetization azimuth of the schistose granodiorite distributed in Kuwanosawa was regarded as almost NS. The measured magnetization azimuth of the core specimen obtained from the same rock mass was also made NS-based, and measurement of the fracture in the neighborhood was made. As a result, it was found out that the NNW system was dominant in dikes and that there was the NE system in most of the small geothermal channels. The fracture system of well tended to develop around the boundary between granite and metamorphic rock, and it was thought that this part could be a reservoir if temperature conditions are prepared.

Environmental factors affecting conversion efficiency of solar cells were measured in Tokyo and Nagano to comparatively study the difference. In the study, measurement was made of intensity of global solar radiation on an inclined surface (insolation intensity), ambient air temperature, and distribution of spectral solar radiation at the two points. Also measured were output characteristics of polycrystal silicon solar cell modules and amorphous silicon solar cell modules. The result of the comparative analysis was as follows: The annual inclined global solar radiation amount integrated in 1996 is 27% more in Nagano than in Tokyo. The weighted average insolation intensity in Nagano is 0.09 kW/m{sup 2} higher in Tokyo. The weighted average cell temperature in Nagano is 4degC lower than in Tokyo. The effective spectral ratio in Nagano is 1-2% lower both in polycrystal Si and amorphous Si than in Tokyo. Thus, it was inferred from that environmental factors are different that conversion efficiencies of photovoltaic modules were different. 6 refs., 5 figs., 5 tabs.

Among the EDS, H-Coal and SRC-2 lined up in the coal liquefaction project of the U.S., the SRC is aimed at producing 6,000 t/day as a module for a 30,000 t/day commercial plant. They expect Ash contents (iron, sulfur, etc.) in coal without basically using catalysts. The products are applicable to fuels for electricity and gas for the moment. In the element technology, there are some problems in manufacturing hydrogen by gasification of residuals as well as in slurry systems, reaction towers, etc.. In the 30,000 ton commercial plant, the coal-liquefied oil costs $19.89/bbl (price as of 1978) assuming coal costs $29.47; therefore, the feasibility is strong as a substitute for petroleum. Japan's share for the required funds will be 86.8 billion yen (if 250 yen per dollar). Since the kinds of coal are conceivably increased in number through the improvement of the process, the Pacific rim countries and these which lie on the Indian Ocean are assumed to be the major coal producing countries for Japan. The stability in storage of coal-liquefied oil is experimentally excellent, as is the compatibility with petroleum products for example. Great results can be expected in the technical know-how and the spread of element technology for Japan. (NEDO)

In the use of hydrogen as fuel, there is the problem on NOx emission. The amount of NOx emission is not as much as in the use of coal or oil, but is more than in the use of natural gas or town gas. However, it can be said that hydrogen is an ideal fuel if considered that it does not emit other air pollutants such as CO, HC and soot/dust which are usually associated with hydrocarbon base gas fuels, and also that hydrogen forms a circulation system which is ecologically sound. The flame of hydrogen is non-luminous, but the flame temperature is high. The formation of NOx depends strongly upon the flame temperature, and therefore, in the design of hydrogen burner, it is necessary to well mix it with air and to avoid the production of the local high temperature region. Further, when using hydrogen to large boiler, the combustion technology to control NOx reduction is needed. About the hydrogen flame, the matter to be noticed is an experimental result that NOx reduction was observed by adding trace ammonia to hydrogen gas. If this method can be successful, NOx can be reduced with no increase in fuel consumption. It leads to hydrogen's reaching a position of clean energy. (NEDO)

With an intention to solve environmental problems and energy problems simultaneously in Sumoto City, Hyogo prefecture, surveys have been performed on feasibility of introducing biomass energy in the district. The dairy farming in Sumoto City has a trend of increase in the number of livestocks being fed in individual farms, and increase of milking quantity per livestock (increase of sewage discharge amount), with the increase of excessive excreta amount causing a problem. The Sumoto Dairy Farming Association is experiencing generation of excreta of 156 tons a day, which requires manure handling and disposal of 112 tons a day even after deducting the field dispersion. Discussions on a biogas plant with a capacity of 100 tons a day call for biogas generation amount of 2,500 m{sup 3} a day, electric power generation amount of 4,500 kWh a day, fuel cell size of 100 kW x 2 units, and heat generation amount of 6,000 kWh a day. A total of the estimated project cost amounts to 2,450,000,000 yen, the annual running cost to 65,280,000 yen, and the annual income to 82,000,000 yen. The electric power generation cost is 135 yen per kWh, the heat production cost is 952 yen per liter (converted to kerosene), and the saving amount due to excessive electric power and heat utilization amounted to 10,700,000 yen. The annual amount of CO2 reduction is 1330 tons. (NEDO)

Described herein are the reports presented to the industrial technology subcommittee, 17th symposium of NEDO projects. For development of high-efficiency industrial furnaces by high-temperature air combustion (including regenerative combustion), high-temperature air above 1000 degrees C is used, where carbon dioxide and NOX are possibly abated by 30% or more and 50%, respectively. The worldwide development is also described. For production of high-function ceramic materials at low temperature, the soft solution process is proposed for the in-situ production of these ceramic materials from the aqueous solution without using high temperature or high energy. For example, the high-functional ceramic material can be produced in-situ on a substrate by reacting the highly active aqueous solution with the substrate by a combination of, e.g., the hydrothermal and electrochemical reactions, without needing post-treatment under heating. For the marine biological technologies, deposition of living organisms is described. A geodome is developed for utilizing very deep (50m or deeper) underground spaces. It is a dome-shaped space supported by no strut, having dimensions of 50m in diameter and 30m high not to affect the surrounding environments, e.g., underground water. The techniques for creating advanced functional materials are developed by combining, e.g., laser, plasma, ion and magnetic field in diversified manners. (NEDO)

Applicable uses and the market size for photovoltaic (PV) systems were investigated taking into consideration the features and economics of such systems. As a result of computing representative usage examples together with the extent of potential demand for PV, 238 GW for the power source in private homes, 76 GW for green houses, 126 GW for sewage water treatment plants, 4 GW for schools and universities and others were estimated. For the greater number of PV systems already in actual use, non-cost factors acted as major determining factors when deciding on implementation. Promising uses (applicable ideas) seen from the standpoint of non-cost factors were studied in order to develop the PV system market and gain breakthrough for lowering future costs and increasing proliferation for such systems. When it comes to simultaneously decreasing costs and increasing demand for solar batteries in the coming days, it will be impossible to make an immediate transition from the present state of demand for public use and for special use to the final goal of demand as a power source in the home. There is a need for an intermediate demand that can bridge this gap. (13 figs, 9 tabs)

This paper reports the activities of the bituminous coal liquefaction sub-committee in the Sunshine Project in fiscal 1992. With an intention of developing a technology on the process (NEDOL) suitable for liquefaction of wide range of coal types placing sub-bituminous coal at the center, researches were carried out by using a pilot plant, and engineering data purposed for practical application of the technology were acquired. The construction of the pilot plant was launched in fiscal 1991. It is necessary to execute the pilot plant plan steadily in the future, and at the same time, reliably acquire different data by means of supportive researches. Economic performance of the process is also important. The first sub-committee meeting presented the following agenda: the status of constructing the 150-t/d pilot plant, tests and investigations thereon, research works by using a 1-t/d PSU, development of the most suitable coal refining technology, development of a coal pretreatment technology, improvement of the distilled oil distribution, studies on coal liquefaction conditions, and studies on solvent hydrogenating catalysts. The second sub-committee meeting presented the following agenda: the status of constructing the pilot plant, tests and investigations on improving the performance of natural pylite catalyst and circulating solvent, technological investigations on structuring a liquefying reaction data analyzing system, studies using a 1-t/d PSU, development of the most suitable coal refining technology, studies on coal liquefaction conditions, and studies on solvent hydrogenating catalysts.

Surveys and studies were conducted to establish a practical SNG (substitute natural gas) production process. In the study of coal hydrogasification, a mathematical simulation was implemented to estimate the distribution of products with the pyrolytic reaction and the hydrogenolytic reaction controlled independently in the ARCH-2 (advanced rapid coal hydrogasification-2) process, the said two reactions representing the key concepts of the ARCH-2 process. It was then disclosed that a two-stage reaction control would increase the liquid yield. Also, a tentative calculation was made of gas cooling efficiency and cost performance in a process capable of achieving the target liquid acquisition rate. It was then found that BTX (benzene, toluene, xylene) production up to approximately 15% in terms of carbon was feasible and that the SNG price would be 29.03 yen/Nm{sup 3} with benzene priced at 90 yen/kg, these promising a better result than in the ARCH-1 process. The gas cooling efficiency of the ARCH-2 process was but 72.0% or less, however, which demanded improvement. Studies were made, based on the results of studies in progress since fiscal 1990, about what the hydrogasification process for Japan to develop should be. (NEDO)

Surveys and studies were conducted to establish a practical SNG (substitute natural gas) production process. The hydrogasification process that Japan should develop is a flexible process that operates on the three modes of the maximum SNG yield, the maximum heat efficiency, and the maximum BTX (benzene, toluene, xylene) yield. Such being the case, an ARCH (advanced rapid coal hydrogasification) process was proposed, provided with a reactor capable of an ARCH-1 type operation for the maximum gas cooling efficiency and an ARCH-2 type operation for the maximum liquid yield. As for the details of the ARCH process development, the time and priority for development were determined for each of the items in consideration of the technical contents and the steps of development in the flow from a bench plant to a demonstration plant. The technology of char cooling and extraction was specified as the first item to be immediately dealt with. As for the development of the hydrogasification reactor, it was concluded that it was suitable to begin with the development of an injector. According to the development plan, the cost required up to a pilot plant test was estimated at 2 billion yen. (NEDO)

Development has been made on element technologies for an esophageal vocalization aid system. With regard to the speaker, selection and trial production were performed on a speaker used for a phono-coupler to be used in coupling with a telephone transmitter. Performance not differing from that in the currently used telephone set was obtained in the overall characteristics evaluation using a dummy telephone circuitry. For the microphone, two kinds of hands-free microphones were fabricated on a trial basis. In order to develop pitch extraction and amplitude pitch conversion systems, pitch extraction performances were compared and discussed on the following five methods: the auto-correlation method, the Cepstram method, the average magnitude difference function (AMDF) method, the simplified inverse filter tracking (SIFT) method, and the time-domain excitation extractor using minimum perturbation operator (TEMPO) method. The hauling phenomenon, having come up as a problem in an auxiliary digital device, was analyzed to discuss methods for prevention thereof. In developing a voice/unvoiced distinction judgment method, a method using low domain power and high domain power was discussed. Development has been made on exclusive ICs, a voice analyzer, and the using feeling enhancing technology. In developing a total system, a digital unit incorporated esophageal vocalization aid system was developed and improved. (NEDO)

Among the EDS, H-Coal and SRC-2 lined up in the coal liquefaction project of the U.S., the SRC is aimed at producing 6,000 t/day as a module for a 30,000 t/day commercial plant. They expect Ash contents (iron, sulfur, etc.) in coal without basically using catalysts. The products are applicable to fuels for electricity and gas for the moment. In the element technology, there are some problems in manufacturing hydrogen by gasification of residuals as well as in slurry systems, reaction towers, etc.. In the 30,000 ton commercial plant, the coal-liquefied oil costs $19.89/bbl (price as of 1978) assuming coal costs $29.47; therefore, the feasibility is strong as a substitute for petroleum. Japan's share for the required funds will be 86.8 billion yen (if 250 yen per dollar). Since the kinds of coal are conceivably increased in number through the improvement of the process, the Pacific rim countries and these which lie on the Indian Ocean are assumed to be the major coal producing countries for Japan. The stability in storage of coal-liquefied oil is experimentally excellent, as is the compatibility with petroleum products for example. Great results can be expected in the technical know-how and the spread of element technology for Japan. (NEDO)

Group activities in fiscal 1993 are reported. In the study of hydrogenation refining of the naphtha fraction under the project for 'the upgrading of coal oil and the development of oil blending technology,' a hydrogenation experiment is conducted for deheterocyclicity for in the naphtha fraction (90-180 degrees C). The neutralization process is found to greatly accelerate denitrification, multiplying the rate constant 2-5 times at 300 degrees C. In the research and development of application technologies, the ASTM-D4625-86 method is applied to the storage test of crude oils such as naphtha from liquefied Yallourn coal, kerosene, and light oil, and the results are compared with those from natural storage. It is then found that this acceleration test is applicable even to oils from coal liquefaction. In the research and development of novel catalysts, it is found, relative to the 1st-stage hydrogenation catalyst, that an increase in the amount of supported tungsten enhances the activity and life of the catalyst and, relative to the 2nd-stage hydrocracking catalyst, that YD zeolite is effective in prolonging the life of the catalyst.

CO2 emission was quantified through the life cycle of a solar water heater to assess its environment impact. Although LCA (life cycle assessment) originally sums up I/O of all materials and energy through the whole life cycle of a product to examine environment impact, this assessment was carried out for only CO2. Calculation of CO2 emission assumed a natural circulating solar water heater of 200 l in effective hot water capacity, 2.78m{sup 2} in effective collecting area, and 0.5 in average annual collecting efficiency of total solar radiation, and an auxiliary city gas heat source for compensating insufficient heat quantity. The total CO2 emission in the life cycle of a solar water heater was obtained from an industrial association table assuming the life cycles of 10 and 20 years. CO2 emission was estimated to be 5407.1kg-CO2 and 10665.2kg-CO2 for 10 and 20 years, respectively. CO2 emission due to city gas was largest in the total CO2 emission in the life cycle. As a result, for reduction of CO2 emission due to a solar water heater, improvement of equipment efficiency was most important. 6 refs., 5 figs., 3 tabs.

This paper introduces the electrodialysis method, the reverse osmosis method, and the evaporation system for reutilization of waste water in non-collection lines in power plants. In the electrodialysis method, waste water which has been divided and fed conventionally into a desalination chamber and a concentration chamber is supplied into the desalination chamber in the whole quantity to improve the recovery efficiency. A process of supplying sea water into the concentration chamber has made prevention of scaling possible. A small testing machine of high recovery electrodialysis system utilizing sea water was installed in an exclusively coal burning thermal power plant. A 3200-hour verification test has been performed, and its high treatment performance was verified. General waste water in thermal power plants is a waste water relatively less contaminated, which can be desalinated by using the reverse osmosis method to recover usable water at a low cost. However, the recovery rate decreases if salt concentration in the waste water is high. In contrast, the evaporation method can maintain the recovery rate at 90% or higher for salt concentration in the subject waste water of up to 20 g/l. Power plants in the United States built in inland areas use the evaporation method because of difficulty in obtaining sufficient amount of water. 6 refs., 22 figs., 7 tabs.

Oil demand is expected to substantially grow in the future, and the use of oil with combustibles such as hull, baggase and waste is considered from an effective use of energy. A regional model survey was conducted as measures to reduce environmental loads where the fuel mixing combustion with coal and other energy is made the core. The domestic production amount of hull is 2.4-3.0 tons/year, which have a heating value of 3,500 kcal/kg. If hull can be formed into the one storable for a the long term (the one mixed with low grade coal, etc.), it can be a fuel for stable supply. Bagasse is produced 100 million tons/year, which have a heating value of 2,500 kcal/kg. Among wastes, waste tire, plastics, waste, sludge, etc. have a lot of problems in terms of price and environment, but each of them has a heating value during 3,000-10,000 kcal/kg. As to the coal combustion, the pollutional regulation on it is strict, and much higher processing technology is needed. The technology of coal fuel mixing combustion with other energy has not risen higher than the developmental level. Though the technology is a little bit higher in price than the coal fuel single combustion, it is viable. 38 refs., 32 figs., 65 tabs.

From the viewpoints of technology, industry and goods, the iron/steel field was characterized based on the statistic data, and especially automobile use steel materials were selected such as cold rolling high tension steel sheet, surface treated steel sheet, and bearing sheet. The analysis of factors of competitive superiority was conducted, and the following were presented: measures for process continuation, and measures taken from the age of equipment and cost indexes. The paper also surveyed the trend of pig iron making/steel making technology in Asia. The present international technical competitiveness in the iron/steel industry in Japan, especially of automobile use steel sheet, is very high. This is because of the well-functioned demand-oriented development, and also as a result of the mutually influentially conducted equipment development such as process continuation and development of new goods, supposing the iron/steel continuous process and reduction in impurities. However, fears are the stagnation in the recent technical development strength and the saturation of new equipment. Moreover, the further heightening is needed of the international cost competitive strength of general-purpose products. (NEDO)

This research program consists of (1) the solid catalyst-aided reforming of various petroleum based oils and heavy coal oils into Solvolysis solvents and the secondary hydrogenolysis, (2) a search for pre-treatment for improvement on the sub-bituminous coal liquefaction yield, and (3) a search for measures for improvement on the brown coal liquefaction yield. Studied in this fiscal year are (1) the high-temperature short-contact time liquefaction of brown coal, (2) the role of catalyst support for selective upgrading of SRC (solvent refined coal), and (3) reforming of thermal melting feature of low rank coal by preliminary deashing at room temperature. In relation with Item (1), it is found that the dehydrogenation or reaction to carbonization of molecules involved in hydrogen donation is structure-sensitive but that thermolysis of coal is accelerated under high-temperature conditions to allow transfer hydrogen to contribute uniformly. It is deemed also that matching is excellent between hydrogen transfer and thermolysis, that the solvent dissolution level is elevated, and that the reaction short in duration inhibits consecutive polymerization reaction. These are supposed to be effective in improving on the liquefaction yield and in rendering heavy constituents lighter. In relation with Item (2), it is found that the experimentally manufactured catalysts are effective in reducing the weight of heavy constituents. In relation with Item (3), a carbonization reforming method is experimentally implemented in which the ash that affects carbonization is further removed by a pre-treatment at room temperature.

Research and development was carried out concerning the automatic parallelized compiler technology which improves on the practical performance, cost/performance ratio, and ease of operation of the multiprocessor system now used for constructing supercomputers and expected to provide a fundamental architecture for microprocessors for the 21st century. Efforts were made to develop an automatic multigrain parallelization technology for extracting multigrain as parallelized from a program and for making full use of the same and a parallelizing tuning technology for accelerating parallelization by feeding back to the compiler the dynamic information and user knowledge to be acquired during execution. Moreover, a benchmark program was selected and studies were made to set execution rules and evaluation indexes for the establishment of technologies for subjectively evaluating the performance of parallelizing compilers for the existing commercial parallel processing computers, which was achieved through the implementation and evaluation of the 'Advanced parallelizing compiler technology research and development project.'

The paper studied the engineering for activating areas using natural energy. A system has started in which electric power companies purchase surplus electric power from the natural energy use power generation such as the wind power and photovoltaic power generation, etc., and a lot of local self-governing bodies in the country plan `projects to promote town` using the system. However, few engineers and makers can plan `a project to promote town,` making effective use of natural energy which is fickle. Therefore, first, the paper arranged the actual status mostly of the cases of `the projects` using natural energy which have been carried out in the country. Next, the trend of the natural energy utilization technology in countries including the U.S. was described. Moreover, assuming model areas in Japan for working out a concept of model projects on the natural energy utilization and town promotion, a concept was proposed making full use of the utilization technology which has now usability. Arrangement is being made for conditions for the full scale spread as seen in the subsidy system for general users. 3 refs., 176 figs., 61 tabs.

This paper explains the involvement of the global environment action plan of Japan Society of Civil Engineers, Agenda 21, with civil engineerings and global environmental problems, as well as the global environment action plan. Global environmental problems require handling the matters in three ways: identification and elucidation of events, effect analysis estimation, and alleviation, avoidance and prevention of the effect. Settlement and proliferation of civil engineering technologies transferred to developing countries demand indispensably understanding such features of the developing countries as social and economic conditions, natural conditions, climates, histories, races, and cultures. Realizing the sustainable development requires the followings: formation of civil engineerings that contribute to improving global environments; development of civil engineerings that make coexistence of human being and other living organisms possible; analyses of effects and mechanisms of global warming and weather change and the corresponding technique and system development; and development of techniques to build resource circulating type national land and cities. It is also essential to move forward positively structuring civil engineerings that contribute to solving such global environmental problems as acid rains and marine pollution, and technical development thereof; providing guidelines on execution of international civil engineering constructions, and technical development thereof; developing civil engineerings in developing countries and assisting training of people.

Offensive odor substances belongs to a quite different field from the perfume inspire of the same sense of smell, and is a substance forming a lot of troubles which is formed in intimate resident environments such as manufacturing factories of the chemicals, incineration and decomposition treatment process of living body relating substances, stock raising facilities, restaurants and others. A material called the offensive odor substance is generally in very low concentration in the atmosphere, most of which is ppm order in its detection limit. And, the offensive odor intensity is proportional to logarithm of its concentration. For example, even removing 99.9% of the offensive odor substance from its forming source, there is remained its difficult countermeasuring problem of no removing as its offensive odor. At present, the offensive odor is severely regulated by means of laws and acts, research on its relating field is active, and its relating publications have become plenty. In this paper, outline on recent state of the offensive odor and its measuring technique was summarized. 14 refs., 6 figs., 8 tabs.

A geochemical survey was conducted by examining soil gas and hot spa water temperature for contributing to the clarification of the subsurface geothermal structure in the Hachijojima district, Tokyo. Mercury concentration, carbon dioxide gas concentration, and 1 m-deep temperature were measured at 155 sites; and chemical and isotope analyses were conducted for 10 specimens of hot spa water and 6 specimens of surface water. After examination, 5 significant locations were isolated at the regions of Yaene-Ogago, Taredo, the northern foot of Mt. Nishi to Weather Station, the southern foot of Mt. Higashi, and the region to the south of Mt. Higashi with hot spa distributed therein. The significant locations are situated in the vicinity of a mar that produced deposit by magma-steam eruption, an alteration zone, and the parasitic volcano in Mt. Higashi, and in an area with hot spa distributed therein. It is therefore concluded that they are closely related with volcanic activities. It is inferred that geothermal signs in the Mt. Nishi area reflect a relatively deep-seated structure. As for the mercury and carbon dioxide gas concentration levels in the Mt. Higashi area, it is inferred that they again represent geothermal signs reflecting a relatively deep-seated structure. (NEDO)

For the purpose of elucidating a possibility of existence of geothermal reservoirs in the Haneyama area, Oita Prefecture, survey of the geological structure (geology/alteration zone) was conducted. The survey was made for the area of 280km{sup 2} lying from Kusu Town to Kokonoe Town, Oita Prefecture in terms of the route survey of 174km, fabrication/judgement of 52 rock slices, whole rock chemical analysis of 21 rocks, age determination, analysis of rock mineral, X-ray diffraction, literature collection, etc. As a result of the survey, the following conclusion was obtained. When considering a possibility of existence of heat source near this area, the area near the present volcanic front was regarded as promising. The fracture structure in the depths seen in the gravity structure (part of sharp dip of gravity) is more closely related to activity of geothermal water than the active structure of E-W system near the earth surface newly formed and is important when considering the existence of geothermal resource. The periphery of the Shishimuta sedimentation zone where Takigami, Oodake, Hacchobaru and Oguni are located was especially regarded as an area propmising of geothermal energy. In the survey area, the geothermal potential was the highest near Noya - Mizuwake Pass. (NEDO)

With an object of accelerating introduction of and uplifting consciousness on new energies at Sabae City in Fukui Prefecture, a new energy vision was put into order based on the result of the initial stage investigation having been performed in the previous fiscal year. Solar light and solar heat energies will be introduced positively into public facilities, and at the same time works will be implemented to accelerate the proliferation thereof into general households. The target of introduction by the year 2010y is set to 2,600 kW by photovoltaic power generation, and the introduction thereof is planned to schools, nursery schools, municipality operated houses, and unattended facilities. With regard to solar heat water warmer, the present proliferation rate of about 7.3% will be raised to 15%. Regarding wastes generated from industrial areas, efficient energy extraction by thermal recycling is intended on the assumption of suppression of wastes generation, their re-use, and recycling. Systems may include the bio-gas system, cogeneration, and recovery of energies from plastics wastes. For acceleration of proliferation of new energies in general, promotion of introduction will be achieved on mini-wind power generation, small hydroelectric power generation, and fuel cell automobiles.

Through visits to US universities and research institutes, investigation was made on the trend of global environment-related research and possibility of their exchanging the result of research with the RITE (Research Institute of Innovative Technology for the Earth). To investigate the process technology to utilize microbes harmoniously with the environment, the visit was paid to Cornell University, Battelle Memorial Institute and Risk Reduction Engineering Laboratory, where the investigation was made on the environmental bioremediation with microbial functions and clean process production without by-producing substances to load the environment. To investigate the technical measures against the global warming, the visit was paid to Brookhaven National Laboratory, Massachusetts Institute of Technology, California University, Hawaii University and Pacific International Center for High Technology Research, where the investigation was made, through discussion and exchange of research information and opinion with researchers and engineers, on the possibility of their exchanging the result of research with the RITE. Judging from the investigation of this time, the research which is mutually complementary between Japan and USA is easy to promote, because their respective advanced fields do not overlap with each other. 88 refs., 11 figs., 6 tabs.
