    An International Symposium on the Asian Industrial Waste Issue was held in Tokyo on 4 February 1999, where lectures were delivered by participants representing China, the Philippines, Thailand, Malaysia, and Japan. More 150 people attended the event, with questions and answered animatedly exchanged between the lecturers and the audience. The progress of urbanization is quite rapid in China, with the quantity of waste increasing every years to justify the anticipation that there will be a very sharp increase in refuse incineration in the near future. Raising a serious problem in China these days is the plastic waste. In the Philippines, there are no private-sector waste treatment/disposal facilities and corporations are not obliged to take care of their waste. Consequently, very little treatment or recycling is being undertaken. In Thailand, although waste treatment/disposal centers are in operation financed by the Government and private sectors, the cost is very high, and the Government policy is that private investment will be encouraged and supported in future. In Malaysia, privatization is in progress of the business of managing waste in the solidified form. A comprehensive waste treatment/disposal plant was completed in 1998 by the endeavors of a Denmark-Malaysia consortium, and is in operation since then. (NEDO)

    Tanaka, M. [The Institute of Public Health, Tokyo (Japan)

    1998-05-15

    This paper describes waste management in the world. Richer countries produce more wastes with their contents diversified. Poorer countries produce less wastes, which will not present problems in terms of quantity and quality if individuals will dispose of them properly. Household and kitchen refuses in developing countries are organic in nature, and contain more water. Refuse collectors using such animals as donkeys and horses are still seen. Cases of performing intermediate treatment such as incineration are few, and land reclamation is the main treatment. Neither soil covering nor mud water prevention measures are taken. Smoke stays in air throughout year due to open dumping and open burning, and foul water seeps out. Scavengers (people who collects valuables from dumps) exist, who recover such resources as metals and plastics to make their living. Some of the countries make kitchen refuses into compost. In industrialized countries, ratio of containers and wrappings is high in refuses, which are collected by mechanical recovery vehicles, and carried to incineration facilities and reclamation areas. Securing reclamation areas is difficult. Resource recovery is in a trend of mechanization. Pollution preventive measures are also taken at high levels by means of waste processing. 2 refs., 2 figs., 2 tabs.

    This paper describes technologies and devices suitable for disposing of sewage and waste water produced in a ship. Methods for disposing of sewage in a ship include such physico-chemical disposition methods as disinfection and sterilization, and such biological disposition methods as activated sludge sewage disposition and catalytic oxidation (biological membrane treatment). Sewage treatment devices include a storage tank type sewage treatment device often used in inner sea liners such as ferry boats, and a biological treatment device (aeration device) used as a mainstream in merchant ships, large passenger liners, and governmental ships. With the storage tank type sewage treatment device, sewage is stored in a storage tank provisionally while a ship is cruising in a discharge prohibited sea area, and discharged in a sea area allowing the discharge or when the ship enters a port. The method is simple, but limited in storage volume. An activated sludge sewage treatment device consists of a tank divided into an aeration chamber, a sedimentation chamber and a disinfection chamber, an air compressor, a chlorine dissolving apparatus, and a screen. Sewage is digested and decomposed by activated sludge, and the top clear water is disinfected by chlorine, and then discharged. 1 tab.

    This paper explains treatment of wastes produced in ships. Wastes produced in ships should be essentially treated on ships. Since storage and transport of difficult-to-treat wastes to harbor for land treatment is expensive, wastes produced in ships are treated on ships as much as possible. Combustibles such as waste oil, plastics, paper and wood fiber waste are treated by incinerator. Food waste is dumped into the sea after crushing by disposer. Excrement and urine are dumped into the sea through a waste water treatment plant. Oil content in oily bilge is burned after heating and vapor separation. Food waste is temporarily stored in ships because its dumping along the coast and into harbor is impossible. Kitchen refuse decomposer utilizing bacteria was proposed for ships. Press for used cans and crushing/thermal compaction/storage equipment for plastics were also put on the market. The primary regulation on diesel engine exhaust gas may be cleared by improvement of engine bodies. 1 ref., 1 fig., 1 tab.

    A cement-based filler is one of the back filling materials used in radioactive wastes disposal facilities. This paper describes fundamental tests performed on a filling material as to its filling performance, water permeation characteristics, and adsorption property to cerium by using the normal cement mortar (SM) that uses the water-to-cement ratio of 40% and the silica fume mortar (SFM). Furthermore, model wastes were fabricated by using a filling mortar of about 1 m{sup 3} and a 200-liter drum, which were used for tests on the filling and water cut-off performances. The result of the fundamental tests revealed the following matters: all of the materials show good filling performance and adsorbability when an adequate amount of high-performance water reducing agent is mixed; and the diffusion coefficient of the SFM is less than one tenth of that for the SM, showing high water cut-off effect. It was made clear from the tests using simulated test pieces that the Lugeon test value and water permeation coefficient of the SFM is less than half of that for the SM, and high water cut-off effect can be obtained by using the SFM. 11 refs., 8 figs., 4 tabs.

    Discussions are given on treatment methods that can utilize scallop cultivation wastes effectively. Tests to incinerate and convert the main scallop shell content, calcium carbonate, into calcium oxide (CaO) discovered optimal incinerating conditions of a temperature at 750[degree]C and a duration for 30 minutes, and 700[degree]C and one hour. CaO content in burnt shells was so high that they could be used as a raw material for quick lime. In the incineration and conversion tests on wastes from shell processing factories, the result of X-ray diffraction in chemically combined conditions of inorganics before and after the incineration revealed that the main component Ca existed as CaCO3, which may be converted into CaO when incinerated. The result also showed that the second component, Mg, existed as MgO after the incineration. From the above results, incinerating the wastes from shell processing factories at 750[degree]C would be capable of incinerating organic components completely and reducing their weights. Because the inorganic residues have high CaO content, they could be utilized effectively as a quick lime raw material. Although shells to be incinerated have low salt content because of having been boiled, salt content in scallop processing factory wastes will require discussions on possibilities of its corroding an incineration furnace. 3 figs., 7 tabs.

    This paper introduces a refuse crushing apparatus to reduce for storage the volume of refuses produced on board a ship by crushing. Refuses to be crushed are solid wastes including solid combustible refuses such as paper, wood pieces, and cloths, non-combustible refuses such as empty cans, metals and glass, and refuses unsuitable for combustion, such as plastics and stylofoam. Crushing methods include impact system, compression system and shearing system. The shearing system shears and crushes refuses by using blades rotating at a low speed. The system has a wide range of crush ability and excellent versatility, generates low levels of dust, noise and vibration, and is suitable as a marine use refuse disposing apparatus. However, empty cans and PET bottles are more difficult of getting into cutting blades requiring a large amount of time for crushing. Therefore, it is more suitable to reduce volume of refuses by using a compressor or the like apparatuses, and then crush them by using a double-axial shearing crusher. Stylofoam causes its crushed pieces to be electrically charged and deposited onto the apparatus, hence it is more suitable to reduce the volume of refuses and make them brittle by heating, and then crush them by using the double-axial crusher. 2 figs.

    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.

    For the natural environment preservation, effective utilization of resources, and maintenance of the ecosystem, an international cooperation model was proposed for the environmental harmony type green technosystem. A comprehensive evaluating analysis of a green forest resource, etc. as the global resource, and an intensive extraction of subjects and needs was made. The analysis was conducted of technical possibility and abstract business development effects toward the industrialization with high values added which is in harmony with the environment. As a case study, the Papua New Guinea area, Malaysia was selected and re-evaluated. For this typical tropical forest area, a new technical system was studied based on the natural environment, industry/economy, social/cultural assessment, etc., and a model for industrializing new international cooperation was proposed. For the model making for industrialization, various steps to be taken and conditions to be prepared were studied and arranged for the realization. Upon going ahead with the international technical cooperation, Japan, a large lumber consuming country, needs to always consider the fostering and effective use of lumber resource in particular. 27 refs., 28 figs., 30 tabs.

    A study was conducted on a technology to melt shredder dust and non-combustible wastes directly by using coal, reduce their volume and re-utilize them. The elementary study on a high-temperature melting and treating technology set such targets as optimizing the melting and treating technology in correspondence with properties of materials to be treated, by using a small melting test plant, achieving a volume reduction rate of 1/200, and reducing treatment cost. In order to make innoxious the different kinds of environmental loading materials contained in exhaust gas from a high-temperature gasification and direct melting system, discussions were given on an optimum control condition for the exhaust gas system facilities. Furthermore, physical properties of discharges (slags nd metals) were investigated to discuss material re-utilization. In discussing optimal systems, three kinds of systems including two types utilizing fuels were proposed as high-temperature gasification and melting treatment process from a viewpoint of technology and cost. Respective systems were compared with each other on treatment cost, and their priorities were identified. 56 refs., 50 figs., 55 tabs.

    This technological development is intended to develop a process technology to dispose adequately of air bags convergently when they are removed from waste cars, with consideration paid on environmental and safety aspects. This technology that can dispose of air bags remaining as air bag modules (ABM) in large quantity and adequately can solve the problems of maloperation in opening them in cars and noise in conventional disposal methods. The recovery and disposal system using an inflator can be expected of reducing work load on dismantling contractors and enhancing the work safety. Furthermore, the energy saving process utilizing combustion of plastics can save resources. However, this technology has not elucidated how dioxins, dust, smoke, sulfides, and nitrogen oxides are generated and how the generation can be prevented. Therefore, an exhaust gas dioxin testing facility and an exhaust gas treating facility were installed additionally to the existing heating treatment facility to develop a disposal technology to treat adequately the exhaust gases generated when ABMs are disposed conveergently in large quantity, and treat the waste water discharged from the facilities. Fiscal 1998 has performed preliminary tests to accumulate fundamental data, and design and installation of the above two facilities. (NEDO)

    To reduce the environmental pollution caused by lead eluted from the electronic equipment waste, the R and D on lead-free solder were conducted and the results were summarized. As to the basic characteristics, the evaluation test method was studied in terms of the range of melting temperature, mechanical strength, wettability and joint strength, to select a uniform test method. As the lead-free solder, Sn-Ag alloys were mainly used and mixed in a combination of Cu, Bi and In. Changes in characteristics were made clear by adding trace elements such as Ge, Mn and P. Relating to the applied characteristics, in selection of solder materials, materials were selected for which evaluation of the commercialization is proceeded with from a viewpoint of promotion of commercialization. Concerning the experimental evaluation of characteristics of lead-free solder in mounted substrates, it was indicated that basically lead-free solder can be practically used. Further, it was indicated that the Sn-Ag-Cu-Bi system depends not on solder composition but on active force, printing accuracy and flux characteristic of solder paste, that improvement of solder paste has an effect on mounting characteristics.

    In order to promote the joint implementation based on COP3, a survey and a discussion were given on improvement in wastes treatment systems and reduction of greenhouse effect gas emission in Tapioka starch manufacturing plants scattered in Indonesia. Currently, the wastes are disposed untreated, discharging methane gas into atmosphere as a result of putrefaction and contamination. Ten factories were picked up as the object of the survey. The following processes are to be adopted as the most suitable method for treating waste water and waste substances: solids (peels and fibers) are composted, and rinsing waste water is subjected to simple aerobic treatment; purified waste water is recovered of methane gas by means of anaerobic treatment; and the reduction amount of greenhouse effect gas converted to CO2 is estimated to reach 314,824 tons per year in total of the ten factories. If the carbon dioxide discharge right can be transacted at a sales price of a dollar per ton, assuming the compost sales price at 200 Rp./kg, the IRR will be 10% or higher, making the project very highly profitable. An IRR of 8% may not be assured unless the discharge right can be sold at 5 dollars per ton if the compost sales price is 150 Rp./kg. The Indonesian Government expects financial assistance from Japan for the pilot plant demonstration. (NEDO)

    An ice storage cold-water manufacturing unit that can manufacture cold water at a stable temperature near 0degC by using midnight power and a solid organic waste treatment facility were developed. The high-speed melting of ice is required to stabilize the cold-water temperature. Therefore, experimental investigation was performed. A piece of flake-shaped ice whose surface area and storage quality are balanced was used. A system that melts ice using the melting tank installed outside an icebox, and a high-speed melting system of ice based on the mixing unit installed in a melting tank were also used together. In the validation test of a prototype for smaller food factories, the following was confirmed. Manufacturing of cold water at about 1degC, amount of cooled water, stability of output water temperature for a change in water temperature, and good storage of ice in an icebox. In the prototype developed for a solid organic waste treatment facility, satisfactory performance was confirmed for following. Temperature in a fermenter when wastes were put, moisture content in a fermenter, pH value, net loss when the refuse of fish is put, and saving of an electricity rate. 6 figs., 2 tabs.

    The composting method can be divided roughly into the aerobic process and the anaerobic process. The former one is a method of processing which decomposes organic substances in the work of the micro-aerobion by blowing the air in the compost material layer, and the latter one is a method for mainly decomposing the organic substance by the work of the anaerobiont microorganism without the positive contact of the material and air. Since the anaerobic process has a slow reaction rate, and emits a resistant odor, an aerobic process system is taken in many plants. In this paper, the aerobic process is described. At first, a fermenter, crush equipment, screening system and a deodorizer as the composting facilities are explained, and the problems of the composting process are described. The largest problem is to exploit a demand without a seasonal variation. It is necessary to exploit the market except for farmland and orchards in order to avoid the seasonal variation. For example, there is a demand for compost in parks, green land and golf courses. It can be also utilized for the normal plane protection of roads and railways. In addition, there are utilization applications such as barn bedding, earthworm culture floors and a deodorant of sewage urine disposal facilities. (NEDO)

This system comprises a system to utilize ozone by using silent discharge and oxygen enriching device, and a living organism/activated charcoal treatment system. The latter system utilizes living organisms deposited on activated charcoal surfaces to remove polluting substances including ammonia. The treatment experimenting equipment comprises an ozone generating system, an ozone treating column, an activated charcoal treating column, an ozone/activated charcoal control device, and a water amount and quality measuring system. An experiment was carried out using an experimental plant with a capacity of 20 m[sup 3]/day on water taken from the sedimentation process at an actual water purifying plant. As a result, trihalomethane formation potential was removed at about 40% in the ozone treatment, and at 70% in the whole treatment combining the ozone and living organism/activated charcoal treatments. For parameterization of palatability of water, a method is being studied that utilizes nuclear magnetic resonance to investigate degrees of water cluster. The method is regarded promising. 1 ref., 4 figs.

    A practical and specific working manual was prepared that satisfies the standards and criteria defined in the relevant law such as the Sanitation and Environment Ordinance No. 249, the guideline for generation of dioxins caused by refuse disposal, and that enables the reports evaluating the wastes quantitatively to be submitted to heads of the local governments when persons in charge of planning the introduction of wastes power generation at local governments discuss the wastes power generation systems. Taking general combustible wastes and sewage sludge treatments as the object, this paper details from the economic performance to size of wastes treatment at the priority limit for the power generation facility introduction. The subject power generation systems include the following: the stoker furnace/separation type ash melting furnace power generation system, the fluidized bed/separation type ash melting furnace power generation system, and the direct type gasification melting furnace power generation system, whose establishment of safety, reliability and stability have been verified by full-size system operation record available at the local governments, the gas turbine re-powering composite type power generation system (gas turbine power plants are installed beside the incineration furnaces) that makes high-efficiency power generation possible, and the RDF power generation system (power generation by mixed combustion with general refuses, and power generation using RDF (refuse derived fuel) exclusive combustion). Other important discussion and assessment items include environment and resource utilization performances. (NEDO)

    Toyota`s waste reduction efforts based on a drive for dealing with the source of waste generation are introduced. For the propulsion of the policy for dealing directly with the origin of waste, it is necessary to convert the existing manufacturing processes that give high priority to product quality and low production cost into environmental impact reduction oriented processes. In particular, conversion of materials into those that are easier to recycle, technology for reducing defective products, technology for the completion of recycling within the process involved, and the simplification of all the processes are mentioned. For the cleaning job in the machining process, a detergent enhanced in oil/water separating capability is developed, and this prolongs doubly the detergent replacement period and decreases the waste liquid to a 1/4 or less of what the conventional method produces. For the handling of foundry sand that is yielded in great quantities, a flow classification system is developed to replace the conventional gravitational classifier, and the reusable coarse-grain sand in the collected dust which occupies approximately 70% of the whole waste is now recovered for reuse. In the vehicle body coating process, a newly-developed robot arm type coating system is developed, which halves the coating waste. 2 refs., 9 figs., 1 tab.

    Discussions were given on effects of acid pretreatment and tetralin swelling in Wandoan coal on a Curie point flash pyrolysis (which used a Curie point pyrolyzer). Residue yield loss effects were obtained at 3.9% in hydrochloric acid pretreatment, and 6.2% in acetic acid pretreatment. The effects of tetralin swelling pretreatment were compared in the similar manner in terms of the residue yield loss. The effects were 4.0% in untreated coal, 2.0% in the hydrochloric acid pretreatment, and 0.6% in the acetic acid pretreatment. It is thought that components that can be activated by acetic acid have already been activated, but the remaining components would not be activated by tetralin. Average microporosity (area) in the remaining particle as a whole shows very little difference both in acetic acid pretreated coal and untreated coal. However, with the acetic acid pretreatment, pores smaller than 4{mu}m{sup 2} disappeared, and pores as large as 205 to 411{mu}m{sup 2} increased largely. This phenomenon was observed as an increase in foaming degree under microscopic observation, even if the average microporosity remains equal. Thermoplasticity of the coal increased, and so did volatilization reactivity as a result of the acetic acid pretreatment, resulting in appearance of a large number of large pores. 6 refs., 2 figs., 2 tabs.

    Chlorination of drinking water is an inevitable process for the purification of drinking water. It has been made clear that injected free chlorine reacts with organic matter in water to produce chlorinated by-products. Many of those compounds are toxic, and studies have been made on the international water quality standard. Water quality standard has been revised also in Japan. The sources of organic matter which is the cause for production of chlorinated by-products vary according to the kinds and conditions of the water source for drinking water. Removal of precursors in the original water, removal of by-products, and change in the disinfection system with alternate disinfectant for chlorine are among the measures for decreasing chlorinated by-products at water purification plants, but the first one is employed as the basis method. It is expected that more severe regulation may be imposed on the quality of the water source for drinking water, and more strict oxidation and disinfection systems is inevitable for water management based on the new water quality standard. 10 refs., 5 figs., 2 tabs.

    This paper evaluates influences of stacking of incident angles against the reflecting surface on the resolution. Basic equations for evaluating the influences were deduced. A simple evaluation method has been provided using these equations. The present evaluation method is considered to be useful for acquisition design, processing, and interpretation of data as an indicator. According to the equations introduced in this study, there are some demerits for stacking traces whose incident angles were large. A total reflection region often appears due to the decreased resolution, and the vertical resolution decreases prior to stacking. Occasionally, it is not effective to remove traces having large incident angles from the viewpoint of resolution. In practice, the selection of most suitable trace through trial and error is not easy due to difference in individual regions. An evaluation method must be discussed, by which the optimal trace can be selected automatically during the data processing. 6 refs., 15 figs.

    Wastewater containing organic pollutants is generally treated by the biological methods like the activated sludge process, etc. But these biological methods are not necessarily applied to the wastewater with high salt content generated at pickles making plants, etc.. In this report, with the objective of application of the electrolytic oxidation treatment to the organic wastewater with high salt content of pickles making plants, the effects of such conditions as pH, temperature and current, etc. on the treatment rate and treatment efficiency were examined, furthermore, the treatment process was simulated on the basis of a simple reaction model, and its simulation results were compared for study with the experimental results. The results are shown below: No effect of pH was observed, hence no pH control is required; The higher temperature of the wastewater accelerates the treatment rate; It was considered that in high temperature, a loss due to autolysis of hypochlorous acid increases, but the current efficiency of generating hypochlorous acid increases too and since the latter effect is bigger, the above phenomenon occurs. The current has a small effect on the treatment efficiency. With the simple reaction model, the change of residual chlorine concentration, etc. with time can be reproduced semiquantitatively. 7 refs., 6 figs.

    Discussions were given on a small-scale sewage disposal of about bod 200 mg/l, for which no many examples of use have been hitherto available, using a system combining an anaerobic reactor and membrane modules. Experiments had been carried out from 1988 through 1990 as a part of the Aqua-Renaissance Project. The test equipment wza installed in the premises of the Chigasaki Coastal Research Facilities operated by the Ministry of International Trade and Industry, which used sewage flowing from the adjoining sewage treatment plant for the southern area of the Fujisawa City. The test facility consisted of a system comprising a pretreatment facility, SS decomposing reactor, fluid-bed reactor, separation membrane modules, nitrogen removing facility and micro-organism activity measurement. The test facility was constucted assuming a treatment of 10 m{sup 3} a day. The system was divided into a composite system, A system and B system to operate the system in simplified flows. As a result of comparing the composite system, A system and B system, it was found that B system can deal with wider range of disposal for a small-scale sewage treatment of about 1000 m{sup 3} a day. 6 refs., 14 figs., 3 tabs.

    At present, Ni-Cd battery is mainly used for the power source of portable AV devices and back-up power source of computer memory. From an environmental point of view, however, Ni-hydrogen battery in which hydrogen storage alloy is used instead of Cd as for the negative electrode has been developed. The productivity of Ni-hydrogen battery is not so high because it takes a very long time to activate the battery after it is assembled. This invention solves the problem. According to the invention, the hydrogen storage alloy containing Ni is immersed in a non-oxidizing acid aqueous solution containing dissolved oxygen by 1 mg/L or less. If a large amount of dissolved oxygen is contained in the acid solution, metal appearing on the surface of alloy by the acid treatment is directly combined with the dissolved oxygen, resulting in the re-formation of metal oxide. So that the effect of oxide removal by the acid treatment is reduced. Using the treated hydrogen storage alloy in the Ni-hydrogen battery makes it possible to produce the battery which has a high initial activity and a good storage property with less self-discharge. 2 tabs.

    A nickel-hydrogen battery using a hydrogen storage alloy takes considerably long time for the initial activation treatment after the assembly of the battery. In this invention, a hydrogen storage alloy containing nickel is immersed in an aqueous acid solution or an aqueous alkaline solution and washed with a solution containing a complexing agent to form a nickel complex by a reaction with Ni(OH)2 in a concentration of 10{sup -6} to 10{sup -1} followed by washing with water. By using this method, hydroxides, particularly, Ni(OH)2 deposited on the alloy surface on the treatment of the hydrogen storage alloy with aqueous acid or alkaline solution can be removed efficiently to afford the hydrogen storage alloy with a high initial activity. The hydrogen storage alloy which is the object of this treatment method is AB5 type and AB2 type alloy used for a nickel-hydrogen battery and an alloy composed of nickel is particularly preferable. The complexing agent is selected from ammonia, ethylenediamine and cyanides. 2 figs., 6 tabs.

    The activated sludge process and other biological treatments, though utilized for most sewerage and drainage water disposals, often necessitate the maintenance to be managed with a professional knowledge so that confrontation is oftem impossible with trouble in management. In the present report, different basic studies are to be introduced of microbial activation by an addition with saponin. Saponin'', etymologically identical with savon'' and soap'', has been being used as natural cleaner, emulsifier and foamer in South America and Europe since olden times, and is used also for the processed food and potable water in the USA. The present experiment concluded that, in case of using it as microbial activator, the activated sludge can be considerably increased in load quantity of disposal by the heightening in oxygen-supplying power, high concentration microbial maintenance, microbial activation, etc. In the future, there will remain many problems unsolved such as what is the optimized condition for the addition depending upon the condition of base material. 3 refs., 6 figs., 1 tab.

    Recently, geological analysis using remote sensing data has been put into practice due to data with high spectral resolution and high spatial resolution. There has been a remarkable increase in both software and hardware of personal computer. Software is independent of hardware due to Windows. It has become easy to develop softwares. Under such situation, a portable remote sensing image processing system coping with Window 95 has been developed. Using this system, basic image processing can be conducted, and present location can be displayed on the image in real time by linking with GPS. Accordingly, it is not required to bring printed images for the field works of image processing. This system can be used instead of topographic maps for overseas surveys. Microsoft Visual C++ ver. 2.0 is used for the software. 1 fig.

    This paper reports pre-stack migration in elastic wave exploration as to its algorithm and examples of processed data. The time migration processing hypothesizes that seismic waves propagate linearly. It calculates travel time by dividing the sum of the straight distance from a vibration transmitting point to an image point and the straight distance from the image point to a vibration receiving point with RMS velocity given as a parameter. To maintain the relative relation of amplitude sizes, the signal on an elliptic body is made smaller in inverse proportion to the size of that elliptic body. With regard to apparent interval of input trace as seen from the reflection surface, or with regard to density, the signal is made smaller by cos{theta} times. While this program deals with three-dimensional migration, its output turns out as an arbitrary two-dimensional plane. The program requires a huge amount of data processing, whereas a method is used, that the input trace is divided, each group is processed by using separate computers, and the results are summed up. 3 refs., 4 figs.

    This paper describes chlorination substituting disinfection technologies used in water purification systems. Chloramine treatment is regarded as effective in reducing trihalomethane (THM). Chlorine is injected in the initial stage in the form of free chlorine to disinfect pathogenic microorganisms in a short time, which is then added with ammonia to convert it into chloramine for further utilization. Chlorine dioxide has not been used in Japan, but introduced in Europe and America to treat THM. Ozone has the strongest oxidizing power, and is used for disinfection, virus inactivation, decomposition of THM precursors, and removal of fungus odor. The ozone treatment will produce aldehyde if an organic matter is present, but aldehyde can be removed by treatment using organismic activated carbon. Ultraviolet ray treatment has an advantage of being difficult of producing byproducts. This system was experimentally compared with free chlorine treatment on disinfection effect, mutagenicity, suppression of producing THM byproducts, and odor removal. In order to assure reliability of microorganismic and chemical safety in tap water supply systems, assurance by considering the entire system is important, not only by operating the disinfection units, but also combining such physical water purifying technologies as coagulation, sedimentation, filtration, and membrane treatment. The use of chlorine substituting disinfectants is also a part of the conception. 6 refs., 8 figs., 5 tabs.

    An investigational study was conducted of the brain function aiming at developing an interface with the same function as humans have. In the study, the most up-to-date information/knowledge and future problems were examined on brain measurement, brain modeling, making a model an element, and the brain function data processing system. As to the brain measurement, the paper took up the multielectrode simultaneous measuring method and the optical multipoint measuring method as an invasive measuring method, and the functional magnetic resonance imaging, near-infrared spectroscopy, magneto-encephalography, and electro-encephalography as a non-invasive measuring method. Relating to the brain modeling, studies were made on senses of sight and smell, the movement control and the learning. As to making a model an element, how to make the modeled function a chip on silicone for example becomes the problem. Reported were two reports on making the sense of sight an element and one report on making the parallel dispersed processing mechanism of brain an element. About the brain function data processing system, three reports were made on the present situation, matters in question, and the future development of the system in the case of catching data processing as a system taking a step ahead from making the model an element. 250 refs., 74 figs., 11 tabs.

    A biological reduction method in which hazardous hexavalent chrome is reduced by bacteria is explained as one of the bioremediation technologies. Those bacteria are separated from active sludge in the urban sewage treatment plant. The hexavalent chrome-reducing bacteria were isolated by cultivating the sludge. They were Enterobacter cloacae which are intestinal bacteria. Then, they were named HO1 stock. As a result of analyzing the reduction mechanism, it was made clear that the function is localized in the cellular endosporium and that the reduction is made by utilizing the electronic transfer system of endosporium. Under both aerobic and anaerobic conditions, they convert the hexavalent chrome into the trivalent chrome outside the cells. As a result of test, it was known that 5mM hexavalent chrome can be treated in one day. A quick reduction was confirmed also through an experiment in which carbon source was added to the industrial wastewater. If used for the treatment of sludge/water contaminated by hexavalent chrome, the present reduction by bacteria has the following advantages: The highest reduction rate is given near pH=7 at ordinary temperatures. It is not necessary to add chemicals. Energy is not needed. It is a disadvantageous fact that the present bacteria, if exposed to oxygen, become inactive. 18 refs., 5 figs.

    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.

    Surveys were conducted of the effect on waste quality of the Law for Promotion of Sorted Collection and Recycling of Containers and Packaging, diffusion of PFI (private finance initiative) involving refuse-fueled power generation, recycling of slag, etc. Questionnairing was conducted for the survey of the effect on waste of the effectuation of the recycling law, size of population supplying the waste and the amount actually incinerated, actually measured data of the composition of incinerated waste, assorted collection programs, amount reducing measures, and the like. Studies were made as to if the empirical formulas applied in the survey of the preceding fiscal year would remain applicable after the coming into force of the recycling law. In the survey of PFI popularization, it was found that the rate it was taken into account for concrete projects was so low as 13.8% though most of the autonomous bodies had cognizance of PFI. It was requested that it be clearly stipulated that 'the conventional subsidies and grants apply also to PFI projects.' In the survey of conversion of residue into molten slag in refuse-fueled power generation and its reuse, four kinds of slag specimens were examined for physical properties, elution, and analyzed for ingredients, and then it was found that they posed no problems like heavy metal elution.

    High temperature and high pressure steam has been investigated for the high efficiency waste power generation technology development. The steam temperature below 300 centigrade is currently employed to avoid the corrosion of superheater, and the generating efficiency is less than 15%. Practical application of 500 centigrade and 100 kg/cm{sup 2} is planned by developing corrosion resistance materials. Environmental load reduction technology has been also developed. For the external circulation type fluidized bed furnace combustion tests using dummy waste in fiscal 1995, the temperature control at bag filter was effective for suppressing the dioxins. When using waste plastics, HCl could be reduced by blowing Ca compounds. Various Cr-Ni-Mo-based alloys have been developed as a corrosion resistance superheater tube material, and are currently tested. For the environmental load reduction technology, the development of pulse plasma exhaust gas treatment method has been continued from fiscal 1993. In fiscal 1995, this method was confirmed using a small-scale test unit, and also tested using a 5000 Nm{sup 3}/h bench-scale unit. The removal rates of dioxins at the outlet of bag filter were 99.8% and 99.3%, respectively. They were found to be affected greatly by the pulse waveform. 13 refs., 107 figs., 24 tabs.

    Case studies were conducted of industrial refuse-fueled power generation using plastic waste, paper waste, and wood chips, and the same using the excretions of cattle. In the study of power generation fueled by mixed waste containing plastic waste, 325t/d, 220t/d, and 130t/d incinerators having the lower calorific value of 5,960-6,401 kcal/kg were taken up, and steam conditions, generator output, generating-end efficiency, station service power ratio, sending-end efficiency, etc., were tentatively calculated. As for cost efficiency, a manufacturer's estimate indicated that commercialization would be impossible in all the cases unless the construction cost was cut down. In the study of excretion-fueled power generation, cases were taken up where medium-temperature fermentation proceeded for the excretions of 620-29,853 dairy cows (32-1,576 t/d). A calculation was performed on conditions that the construction cost and maintenance/utility costs were as estimated by the manufacturer, that the excretion treatment and power generation facilities were covered by subsidies, and that personnel expenses of 6-million yen were necessary. It was then found that there would be commercial viability in case the yield was 790t/d or higher. (NEDO)

    The biological effects of acute toxicity, chronic toxicity, carcinogenicity, etc. of chlorination by-products detected in drinking water in Japan are discussed. The biological effects of representative chlorination by-products such as trihalomethane, haloacetic acid, haloaldehyde, haloacetonitrile, chlorophenol, chloropicrin, etc. as well as the evaluation of mutagenicity in drinking water purification process, for which Ames Salmonella/microsome assay is used for safety evaluation of drinking water, are discussed. The extent of the contribution of mutagenicity of chlorination disinfection by-products to the mutagenicity of drinking water is investigated. It must be admitted that biological evaluation of the safety of water quality is impossible currently by using only the known chemical substances contained in drinking water. The effects of chlorination and ozone treatment which are often applied to drinking water treatment are different each other. 58 refs., 1 fig., 4 tabs.

    Concerning the analysis of data from seismic reflection survey, time migration and DMO treatment are discussed. As a tool for dealing with irregular changes in elevation, a technique is developed that can define the local reference level working effectively in the Kirchhoff-type treatment. In this technique, for each migration or dipmovement trace outputted, processing is repeatedly performed for imaging and local reference level. In dealing with the curvature of a traverse line, a 3-dimensional DMO treatment with cross-dip correction is performed, for the development of a method for simultaneously applying projection and accumulation to stacked traverse lines. A migration projection plane is set separately from the CMP traverse line, and this enables a quasi-3-dimensional treatment approximately corresponding to the curvature of the traverse line. A technique to respond to irregular shock points is discussed, in which input traces corrected by NMO having uniform amplitude distribution are presumed, DMO treatment is conducted for each irregular shock point, and the results are used as a normalization factor usable in the process of real DMO stacking. 6 refs., 2 figs.

    For the purpose of preventing closed waters from eutrophicating, COD regulations and nitrogen and phosphorus waste water regulations are executed in Japan, but practically applicable techniques for this purpose are a few. Concerning technology for removing nitrogen and phosphorus in waste water, this paper describes the actual situation of two industries, electroplating and alumite processing, and applicable techniques. Among various nitrogen removal methods, the biological treatment method has been used practically in many cases and is applicable to practical use. While there are many kinds of physical and chemical treatment methods, applicable methods are limited. In removing nitrogen, the coagulating sedimentation method with Ca salt, Al salt and Fe salt is effective generally for orthophosphate. At electroplating factories, various forms of phosphorus and nitrogen compounds are used as plating chemicals. In treating waste water containing phosphorus, the coagulating sedimentation method is used most frequently. The oxidation + coagulating sedimentation method, the autolysis + oxidation coagulation method, and the evaporation method are effected, though the examples of their implementation are small in number. 15 tabs.

    An examination was made on the possibility of data processing by stacking with scattered waves assumed in a seismic exploration analysis (diffraction stacking method). In the examination, a CDP stacking method and the diffraction stacking method were compared through numerical experiments in the case of imaging a flat reflection surface and an irregular reflection surface. As a result, it was revealed that the CDP stacking method for stacking mirror reflection waves was merely a processing to raise S/N ratio while the diffraction stacking method for stacking with scattered waves assumed contained a migrational aspect as well as an aspect to raise S/N ratio. Consequently, it was shown that, if an oscillator was properly arranged, a structural imaging was possible not by the shape of a reflection surface but by the diffraction stacking method. Additionally, the diffraction stacking method revealed that the imaging effect varied by frequency with the stacking effect decreased at high frequencies, and that no stacking effect decreased at low frequencies but resolution lowered in horizontal direction. 4 refs., 8 figs.

    Concerning a high level treating method of regeneration of sewage water, there are methods of coagulation/precipitation, sand filtering and ozone treatment in addition to the conventional active sludge method. However, none of these methods are perfect from the viewpoint of virus. A film treating method to remove micro-organisms in water is twofold, i.e., microfiltration and reverse osmosis. For such filter treatments, polio virus is most suited as an experimental index for conducting an assessment of the treating ability of viruses. The reasons are as follows: 1. It is the smallest virus among the viruses which are mixed in the water systems. 2. Polio virus is always detected in the study of actual conditions of the viruses contained in the sewage waters. 3. It involves less danger in handling because there are vaccines which are made less poisonous. 4. Separation and quantification of viruses is easily conducted by means of cultured cells. 8 refs., 1 fig., 7 tabs.

    This report describes the historical procedure of a bacterial test for a certain respective bacteria, and also describes the removal of micro-organisms by a water treatment and treatment with disinfectants. The disinfection is made mainly on basis of foreign literature. This is because there exist few literature published in Japan. In a good sense, this is because of the Japanese habit of drinking raw water which has contributed to high level of facilities and the maintenance. If seen from a different viewpoint, the prsent concern is concentrated to a contamination of the underground water by organic solvent and the counter measure against such minute quantity of organic chemicals as trihalomethane and the agricultural chemicals in the golf courses. From the consumers {prime} standpoint, these are of the level of problems that only one affected person increases per year for 100,000 inhabitants even if they continue to drink such drinking waters continuously through their life years. The reality is that it is remote from the realities in life. 37 refs., 9 tabs.

    Change in structures of 3 kinds of coals with different coal ranks and their deashed coals was studied by heat treatment below 200{degree}C. In experiment, crushed Adaro, Taiheiyo and Huaibei coals below 200mesh and their deashed coals were used as specimens. The coal and deashed coal specimens dried in vacuum at 110{degree}C for 3 hours were filled into an autoclave, and the heat-treated coal specimens were prepared by holding them under initial nitrogen pressure of 2kg/cm{sup 2} at a fixed temperature for 30min. Extraction using pyridine as solvent, volumetric swelling using methanol or benzene as solvent, and measurement of the amount of carboxyl and phenolic hydroxyl functional groups were conducted for these coal specimens. The experimental results are as follows. Huaibei coal has developed aromatic ring structure, and its structure is hardly affected by heat treatment. The oxygen containing functional groups decrease by heat treatment over 100{degree}C in Adaro coal and 150{degree}C in Taiheiyo coal, and PS, MQ and BQ also decrease due to aggregation between molecules. 5 refs., 2 figs.

    Data processing method was studied for mise-a-la-masse survey. Mise-a-la-masse method using wells as current sources measures resultant ground surface potential difference, and detects underground local resistivity anomaly. To extract resistivity anomaly largely different from surroundings, the anomaly is extracted as difference between the estimated value of regular resistivity structure (background) and potential difference or apparent resistivity. The following three approximations were attempted to estimate the background: the theoretical equation assuming isotropic homogeneous resistivity structure, that assuming horizontal multi-layered structure and the exponential function of distance from linear electrode for apparent resistivity, and these were compared with each other by numerical model experiment. The data processing method which determines the resistivity structure of the background and the residual of apparent resistivity distribution by inversion analysis using the above second equation, could precisely extract local resistivity anomaly, and estimate the depth distribution of resistivity. 5 refs., 10 figs., 2 tabs.

    With respect to concept of resolution in seismic exploration using the reflection method, detailed considerations were given on processes of forming the resolution as a result of arranging observation points at vibration transmitting and receiving points. In the discussion, numerical experiments were carried out, in which the scattering stacking process is applied in a model having one scatterer existing in homogeneous media. The experiments investigated an imaging formation process of the scatterer when arrangement of the vibration transmitting and receiving points were changed from a coarse condition to a dense condition while the number of transmitting and receiving points is being increased. Resolution is created if waveforms having finite frequencies are used as input, and the imaging is performed by utilizing the limited number of vibration receiving and transmitting points. If the concept of equi-travel plane is used under these conditions, the equi-travel planes perform negation with each other, and it was indicated that visual resolution is expressed by how good the negating effect is. It was discovered that such concept of the resolution is quite ambiguous in terms of engineerings. 2 refs., 17 figs.

    We aimed to develop a system for treating emulsified oil discharged from ship engine rooms. The efficiency of the system aimed at reducing the oil content of the drain to 15ppm or less so that the drain might be discharged into the sea. We have succeeded in developing a biological treatment system using the fluidized bed in which the drain and sludge are efficiently mixed by aeration and stirring. The specific sludge with enhanced oil decomposing ability is used in the system. We performed on - shipboard tests using a pilot test system, whose capacity of the reaction chamber is 0.5m{sup 3} and oil volume load, 0.4kg-oil/m{sup 3}/d, and have confirmed future possible applications to the treatment system for ships. This would bring great reduction in loads on the existing oil separator, saving its maintenance cost in general. 9 refs., 8 figs.

    Demand has been building up for an individual dry type scrubber for treating exhaust gas from the semiconductor manufacturing process. Some factors for the wide acceptance of such a scrubber would be the capability for complete treatment, easy maintenance and safety features, etc. Practical gas analysis and optimum scrubbing techniques would have to be applied, as well as effective monitoring, alarm, and fail-safe techniques. The overall exhaust gas line, i.e. the line connecting the scrubber system and the upstream process, including that extending to pump system, has to be fully considered for enabling effective scrubbing performance. Such factors, which have until now not been given any priority, would have to be fully studied for the development of a practical, individual dry type scrubber. Cooperation on this matter from the semiconductor manufacturing industry would also be essential. 6 refs., 3 figs., 5 tabs.

    In the refining process for the production of copper from pyrites, heat treatment is carried out in a neutral atmosphere so that part of the sulphur will be collected in the form of simple sulfur and that pyrites naturally low in reactivity will be made active. A basic study is also conducted of a very high speed electrolytic method. The chemical aspects of pyrites which are various in composition (mainly CuFeS2) are clarified by X-ray diffraction, and then is subjected to heat-treatment in a 773K-1073K argon atmosphere. There is a decrease in the amount of sulfur at a temperatures not lower than 973K. The X-ray main diffraction line splits for the emergence of some lower angle diffraction lines. The specimen is then subjected to a leach test in a copper chloride base liquor, to disclose that leachability grows remarkably higher in the presence of a great change in the X-ray diffraction lattice constant. An experiment follows in which an electrolyte is allowed to flow at a high speed for accelerating the rate of electrolytic refining in an effort to prevent the passivation of anode and deposition of dendrite on the cathode that is apt to occur when the current density is high. Passivation is prevented when the flow rate is 10m/min or higher in the vicinity of the anode surface for the formation of a smooth electrodeposited surface. 2 refs., 2 figs., 2 tabs.

    Studies are conducted to develop a new wet method for copper concentrates to replace the conventional dry smelting method for the settlement of problems involving the processing of impurities for environmental protection. A specimen of pyrites polycrystals is subjected to leaching at 80 {degree}C in a strongly acidic cupric solution. Findings are that the element sulfur generated in this process does not impede leaching and only approximately 4% of the sulfur is oxidized into sulfur ions; that the presence of more than 2g/liter of bromide ions produced during bromine-aid leaching of gold changes the structure of sulfur for the inhibition of leaching; that circulation of a bromine-containing leaching liquid is not desired since even a small amount of approximately 0.02mol/liter inhibits the leaching rate. Controlled potential electrolysis is performed for the anode in an acid solution containing CuCl, NaCl, and NaBr, for the observation of oxidation/reduction potentials predicted by Nernst`s equation. It is then disclosed that bromine is more effective than chlorine in gold leaching and that the solution potential during leaching agent regeneration enables the monitoring of solution constitution. 2 refs.

    Water-soluble cutting fluids are able to be used for several months to several years if the proper periodical management is carried out. However, the used solution should be treated as waste water when the function-recovery thereof becomes remarkable difficult. On this occasion, the treated solution (drainage) ought to meet the environmental standards prescribed for the purpose of protecting globe environment. Many cases in Japan are that the strict rules are set by each urban and rural prefectures addition to the government ordinance. For carrying out the treatment of waste water efficiently, it is necessary to construct the treating system by mastering the characteristics of waste water and selecting the most suitable one from numerous treating methods. In this paper, after the description on the water-polluting substances and drainage standards, the general treating method of waste water miscible cutting fluids is described. Finally, the concrete cases with respect to the treatment of waste water treatment in automobile manufacturing factories are introduced. 5 refs., 5 figs., 5 tabs.

An outline of the survey is introduced. The system optimization for the commercialization of WPP was studied by considering waste as un-utilized energy. A successful condition and preparation method of the commercialization of a public power plant was also studied, which is a combination of the garbage collection business of a local government and an electric power generation business of a municipal company. For the introduction of the aforementioned system, the problems and supporting methods were studied by making allowance for the profitability of the WPP introduction, because they also need to deliberate it from the economical point of view as electric power companies. Based on the results of foregoing items, commercialization plans, problems encountered from the construction phase through the maintenance and service phase, and the supporting method were arranged. 30 figs., 18 tabs.

The study was made in terms of a large-capacity waste-fueled power plant, estimation of the waste amount considering wide-area processing, size of facilities, comparison of four types of combustion furnace, steam condition/seawater cooling/power generating efficiency, etc. As a result, the following were proposed: As to the size of facilities, a capacity as large as possible is recommended in the light of the scale merit of costs of the waste-fueled power plant and final disposal site and the environmental preservation. Concerning the high efficient power generation, recommended are 450degC and 60-80 ata which are steam conditions for coping with high temperature corrosion. In respect to seawater cooling, the adoption is recommended making good use of locational conditions since the output energy increases by approximately 16%. Any furnace types including the fluidized bed furnace are equal. The amount of dioxin becomes below 0.1ng/Nm{sup 3} because of the control of furnace combustion temperature, residence time, catalytic desulfurization facilities, blowing of activated coal into the flue, etc. 172 figs., 78 tabs.

    With an objective of converting dairy farming wastes and fisheries wastes into resources to be used as energies, this paper discusses development trends and utilization possibilities thereof based on their utilization characteristics. The Tokachi, Abashiri and Nemuro regions produce more cattle wastes, and regions on the coast of the Sea of Okhotsk produce more hepatopancreas of scallop than other regions. The amount of energy from such wastes is subject to large seasonal variations. Methane gas production through methane fermentation is an effective treatment technology, although it is utilized less effectively in Hokkaido. Important is applying the processes depending on energy demand, supply characteristics and regional features. Taking waste utilization characteristics and regionally uneven distribution of resources into account, conceptions on six model systems that could be introduced were structured. The six systems include two types for fisheries wastes utilization, three types for agricultural and dairy farming wastes, and one type for combined utilization of agricultural and fishery wastes. Important factors to select suitable commercial operation sites and promote the operations are stable quantity assurance of waste resources, energy demand, and stable operation, such as could be available in fishery processing complexes and large dairy farming areas. 44 refs., 66 figs., 29 tabs.

    A discussion was given on the fundamental properties of mortar made from cement mixed with silica fume. Four kinds of silica fumes with different particle size distributions were used. The following results were obtained: distribution of pores in mortar admixed with silica fume shifts to the smaller radius side; while the admixture increases the compression strength in mortar, the increasing trend varies depending on the kinds of silica fumes; this is thought to be caused from the difference in pozzolan activity between silica fumes; and the strength increase is caused by densification of the structure due to the pozzolan reaction that is generated after hydration, or in other words, decrease in the pore volume. The applicability of the mortar was investigated as a filling mortar to fill up clearances between wastes. It was found that the filling performance can be controlled by mixing silica fume at an adequate level and adjusting the viscosity. The diffusion coefficient for the admixed concrete is smaller by 30% to one digit than that for the ordinary concrete.

    This paper summarizes the achievements of developing a technology to generate electric power at high efficiency by using a combustion furnace that uses general wastes and combustible industrial wastes as fuel to generate high-temperature and high-pressure steam under a stabilized condition. In the developmental research of the combustion furnace, discussions were given on single-pass and double-pass type stalker furnaces, an internal circulation type fluidized bed furnace, and an external circulation type fluidized bed furnace, whereas technological prospects were established on any of them as the combustion furnace. In developing corrosion resistant super heater materials, demonstration tests were performed by using a pilot plant, corrosion mechanisms were elucidated, amount of corrosion in steam generating tubes was discussed, and corrosion life of super heaters was estimated. In developing a technology to reduce environmental load, developmental researches were carried out on a method to treat waste gases by using pulse plasma to have established nearly completely a waste gas treatment system technology. In the demonstration test using the pilot plant, the operation has started from February 1998, generating stably the steam conditions of 500 degrees C and 9.8 MPa, and the smooth operation has continued.

    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)

    In high-efficiency power generation using general wastes and combustible industrial wastes as fuel, development has been performed on a wastes gasifying and melting power generation technology. This technology is capable of suppressing generation of dioxines, recovering slag that can be utilized effectively, and reducing ash volume, by thermally decomposing the wastes and melting combustion ash at elevated temperatures by using thermally decomposed gases. With regard to the evaluation on high temperature corrosiveness of SH materials and the development of a high temperature dust removing system, a steam heater was designed, fabricated, and installed in a model plant, wherein the operation test has been performed for about 1,620 hours. For the technology of dechlorination during a thermal decomposition process, dechlorination rate of 90% was confirmed at 425 degrees C or higher in a demonstration plant. In addition, developments were made on a low temperature denitration device to avoid re-heating of waste gases, a stable wastes supply system to reduce quantity of self-heated melt limiting heat generation, and a waste plastics blowing technology to reduce external fuel charge quantity. Furthermore, a survey was carried out on the trends in wastes electric power generation technologies. (NEDO)

    To introduce the power generation system fueled by animal waste (excrements), one of the so-called industrial waste, its feasibility has been studied in Koyu and surrounding area located in Miyazaki Prefecture. This report includes the technical feasibility of available quantity of animal waste, chemical analysis of the waste, and basic design of the power generation system containing the furnace model and also its economical feasibility. The available quantity of animal waste in Koyu area is about 169,000 tons a year, which can generate 10.5 MW of electric power. That including the surrounding area is about 219,000 tons a year, which can generate 15.0 MW. The heating values of animal excrements in average and as received are 970 kcal/kg for pigs and 1,230 to 2,700 kcal/kg for broilers. In the case of combustion of mixed broiler and pig excrements, both of the stoker and fluidized-bed model furnaces become refractory furnace construction and provide with heat recovery boiler due to their high moisture content. In addition, the stoker furnace model requires an excrement dryer system as pre-treatment of fuel. For the fluidized-bed furnace of 15 MW grade power plant using the mixed fuel of 50% broiler excrements and 50% pig excrements, the power generation efficiency of 23% can be expected at generator end. The generating cost is around 10 yen/kWh. 27 refs., 61 tabs.

    For the seismic reflection method conducted on the ground surface, generator and geophone are set on the surface. The observed waveforms are affected by the ground surface and surface layer. Therefore, it is required for discussing physical properties of the deep underground to remove the influence of surface layer, preliminarily. For the surface consistent amplitude correction, properties of the generator and geophone were removed by assuming that the observed waveforms can be expressed by equations of convolution. This is a correction method to obtain records without affected by the surface conditions. In response to analysis and correction of waveforms, wavelet conversion was examined. Using the amplitude patterns after correction, the significant signal region, noise dominant region, and surface wave dominant region would be separated each other. Since the amplitude values after correction of values in the significant signal region have only small variation, a representative value can be given. This can be used for analyzing the surface consistent amplitude correction. Efficiency of the process can be enhanced by considering the change of frequency. 3 refs., 5 figs.

    Aiming for the stable operation and the rationalization of factory plant, the color-image processing has been tried to introduce into the on-line system to measure the crystalline color of L-Lysine in its refining process. Because the practical spectro-photometry was used to be employed by manual measurement. In this paper, the calculation formula of the transmittance by spectrophotometry is theoretically introduced by analyzing the relation of Lambert-Beer`s law of luminous transparency with the Kubelka-Munk`s function of the luminous dispersion using color image data. The parameters of the calculation formula were decided by actual measurement, so that the formula with accuracy value of {plus_minus}3% elucidated the possible estimation of transmittance by spectrophotometry. The system was tested on a commercial plant, and some issues are discussed. 8 refs., 8 figs., 3 tabs.

    Coal was treated at high temperature under high pressure in the binary system mixed solvent of water and organic solvent, and the solvent treated coal was liquefied. When the treated coal was treated again by the explosive method in which high temperature and pressure were released immediately, the oil yield was higher than that by the normal method in which high temperature and pressure were reduced gradually to room temperature and atmospheric pressure. In this study, an explosive treatment unit with increased scale of sample amount was newly fabricated. Illinois No.6 coal was treated by the explosive method in a mixed solvent of water and cyclohexanol using this unit. Changes in shape on the surface, specific surface area, and functional groups were analyzed. The explosively treated coal contained more amount of low boiling point components than the normally treated coal. It was suggested that the oil yield of explosively treated coal increased due to the liquefaction of these components during the successive hydrogenation process. For the explosively treated coal, micro pores were fractured by the rapid change in the volume of solvent molecules, and the specific surface area was smaller than that of the normally treated coal. When the treatment temperature was increased from 300{degree}C to 350{degree}C, specific surface areas of both the treated coals increased. 2 refs., 3 figs., 2 tabs.

    Discussions were given on effects of heat treatment at relatively low temperatures as a pretreatment for coal liquefaction on coal swelling and hydrogenolysis reaction. Taiheiyo coal was heated to 200{degree}C for one hour as a pretreatment. The attempted heating methods consisted of four steps of rapid heating (6.7{degree}C/min)quenching (20{degree}C/min), rapid heating/natural cooling (0.7{degree}C/min), heating (1.0{degree}C/min)/quenching, and heating/natural cooling. The swelling treatment was composed of adding methanol benzene into heat treated coal, and leaving it at room temperature for 24 hours. The hydrogenolysis was carried out by using a tetralin solvent and at an initial hydrogen pressure of 20 kg/cm{sup 2} and a temperature of 350{degree}C and for a time of one hour. Hydrogenolysis conversion in the heat treated coal was found lower than that of the original coal because of generation of liquefaction inactive components due to thermal polymerization. When the heat treated coal is swollen by using the solvent, gas yield from the hydrogenolysis reaction decreased due to gas suppression effect, and the conversion was lower than that of the original coal. Heat treatment suggests densification of the coal structure. Swollen coal shows no conspicuous difference in the heat treatment methods against the hydrogenolysis due to the swelling effect. 3 refs., 5 figs., 1 tab.

    To develop a novel process for copper concentrates which includes leaching of copper with acidic cupric chloride solutions, aiming at the recovery of sulfur in its elemental form, and leaching of gold from the residue with dissolved bromine. The effect of bromide ions on the leaching of chalcopyrite with 1.0 mol dm{sup -3} CuCl{sub 2} has been investigated at 353 K, and it was found that bromide ions have no influence on the leaching rate and the morphology of elemental sulfur deposited on the surface of chalcopyrite. Dissolved bromine has trivial effects on the morphology and oxidation of porous elemental sulfur covering the residue. However, the dissolved bromine even at 0.02 mol dm-3 depresses the leaching rate of chalcopyrite significantly. Electrotechnical oxidation of cuprous ions, chloride ions and bromide ions in the solution has examined to understand the regeneration of leachant, and it was found that these ions are oxidized simultaneously on the anode surface under the condition of galvanostatic electrolysis, but these oxidants diffuse toward the bulk of solution and react with their reductants. Thus the redox potential of the solution increases gradually showing the temporary stagnation in potential for oxidation of Cu{sup +}, Br{sup -} and Cl{sup -} ions respectively. (NEDO)

    A vision processing unit was introduced into autonomous underwater vehicles (AUV) to judge the visual situation and to construct an environmental observation platform that can collect wide-range and high-precision measurement data. The cable optionally installed at the bottom of the sea was recognized by vision processing to propose automatic tracking technique. An estimator that compensates for the hough conversion or time delay and a PSA controller that is used as a target value set mechanism or lower-level controller were introduced as the factor technology required for automatic tracking. The feature of the automatic tracking is that a general-purpose platform which can observe the prescribed range environmentally in high precision and density can be constructed because the observation range required by the observer can be prescribed near the sea-bottom surface using a cable. The verification result off Omi Hachiman at Lake Biwa showed that AUV can be used for the high-precision environmental survey in the range prescribed near the sea-bottom surface using a cable. 8 refs., 8 figs., 1 tab.

    Discussions were given on seismic exploration from the ground surface using the reflection method, for surface consistent amplitude correction from among effects imposed from the ground surface and a surface layer. Amplitude distribution on the reflection wave zone is complex. Therefore, items to be considered in making an analysis are multiple, such as estimation of spherical surface divergence effect and exponential attenuation effect, not only amplitude change through the surface layer. If all of these items are taken into consideration, burden of the work becomes excessive. As a method to solve this problem, utilization of amplitude in initial movement of a diffraction wave may be conceived. Distribution of the amplitude in initial movement of the diffraction wave shows a value relatively close to distribution of the vibration transmitting and receiving points. The reason for this is thought because characteristics of the vibration transmitting and receiving points related with waveline paths in the vicinity of the ground surface have no great difference both on the diffraction waves and on the reflection waves. The lecture described in this paper introduces an attempt of improving the efficiency of the surface consistent amplitude correction by utilizing the analysis of amplitude in initial movement of the diffraction wave. 4 refs., 2 figs.

    This paper describes the effect of surfactants on purification capability and living life phases in the living life membrane method and the activated sludge method as biological waste water treatment methods. As a result of treating artificial waste water in an immersion hearth process of the living life membrane method, it was found that LAS added concentration at 50 mg/l or higher would not affect noticeably the quality of water treated under a steady-state operation, but that at 100 mg/l has aggravated the treated water quality by increasing COD. In the case of soaps, the COD in the treated water has aggravated when the added concentration is 70 mg/l or higher. The result of discussing the activated sludge process using urban sewage water indicated that COD in the treated water shows higher value for synthetic detergents than for soaps at the detergent added concentration of 140 mg/l or higher, having affected adversely the treated water quality. An activated sludge treatment process was operated to identify the effects of synthetic detergents and soaps on living life phases in the activated sludge and living life membranes. The result suggests that either the LAS added system or the soap added system presents no problems in a long-time aeration, while activated sludge aerated for the standard period of time has a possibility of abnormally proliferating filamentous microorganisms that can cause bulking in the soap system. 14 refs., 3 tabs.

    Thermo-mechanical treatment was given to improve further the superplastic behavior of SUS 304 stainless steel. In the SUS 304, martensite phase produced by the processing induced transformation may be reversely transformed to the primary austenite phase by high-temperature heating. Crystal grain size is micronized to 1 {mu} m by combining this reverse transformation and recrystallization of the austenite phase. However, the straining rate at that time is as extremely low as 1 times 10 {sup -4}/s or lower, which is insufficient for an industrial material. Therefore, the SUS 304 processed as described above was given again a series of thermo-mechanical treatment of the similar forced cold processing and annealing to ultra-micronize the crystalline particles. Majority of the crystalline particles have come to have a grain size of several hundred nm. This test piece showed a total elongation of 400% or more at a test temperature of 973 K and a straining rate of 1.8 times 10 {sup -3}/s or lower. In addition, the straining rate sensitivity index `m` at that time was 0.45 or higher. The superplastic deformation of the SUS 304 has a high possibility of being governed by dynamic recrystallization. 4 refs., 7 figs., 1 tab.

    The electronic industry should invariably correspond to MPEG-4, when considering the essential conditions for home information equipment of the next generation to be used massively. This project is aimed at formulation of the standard platform for MPEG-4, and identification of the necessary examples and corresponding the necessary tools/functions thereto, to give an impetus for the future development, and to positively provide the additional aids to the tools which strengthen MPEG-4 in the arena of promoting the international standardization. The efforts in this year began with investigations on the assumption of the concrete application examples, considered from the standards' structures, and were concentrated on investigations on characteristic problems involved in each of the system, server and client blocks which constitute the system, and then on identification of the products application, based on the analysis of the MPEG-4 profiles and levels. These have led to selection of an MPEG-4 receiver as the case study item for extracting problems possibly involved in assembling works. (NEDO)

    The image processing technique (reported previously) developed for analyzing combustion in a diesel engine was applied to measuring flow and turbulent intensity in a high pressure spray. Copper vapor laser beam in a sheet form with a thickness of 0.2 mm was injected into the cross section of a spray center in a container. Photographs of the scattered lights of the beam is converted into digital values and analyzed using an image processing equipment. With the laser light emitting frequency set to 20 KHz at a maximum, the flow velocity is measured from changes in photographic image density in two subsequent photographs, and the turbulence intensity from changes in brightness intensity. As a result, it was clarified that the flow velocity and the turbulence intensity in the spray cross section increase with raising the spray pressure. Further discussions are being made on the measuring method, including changes in the image brightness associated with entrance and exit of spray particulates into the laser beam sheet, and effects of the laser beam sheet thickness on the measurements of the turbulence intensity. 6 refs., 6 figs.

    Described herein is a feature extraction processing method necessary for measurement of an object on a stationary image. It imitates the structures and functions of the visual area in the human brain to automatically extract features, such as edges, lines and apexes, from a stationary image or drawing. Information transmitted from the retina to the primary visual cortex area 1 (V1 area) is processed to extract feature candidates from brightness changes on the shading-treated image. The V1 area has the cells which react with long lines and the structure which controls the other cells.

    To develop the culture residue treatment technique using aquatic organisms, the ammonia and nitrate uptake rates of seaweed Ulva and the nitrogen reduction rate of polychaeta annelid Captella sp. with organic sediment predaceous ability were examined in the excretion of Japanese flounder. Nitrogen uptake rate of Ulva was affected by water temperature. It was highest at 20degC, followed at 15degC and 25degC in the order. It was not affected by light intensity between 1500 and 6000 lux. Ammonia and nitrate uptake rates by Ulva were estimated to be 28.2 and 14.6 {mu}g-N/g/h at 20degC under 3000 lux, respectively. Proportion of feces excreted from Capitellid to ingested sediments was 0.38. At 25degC, Capitellid population of one thousand individuals ingested-N at the rate of 24 mg-N/day, and excreted the feces-N of Capitellid at the rate of 7 mg-N/day. About 70% of nitrogen in the sediment was reduced through this process. 15 refs., 9 figs., 13 tabs.

    The needs for low power LSIs have rapidly increased recently. For the low power LSI development, not only new circuit technologies but also new design automation tools supporting the new technologies are indispensable. The purpose of this project is to develop a new design automation software, which is able to design new digital LSIs with much lower power than that of conventional CMOS LSIs. A new design automation software for very low power LSIs has been developed targeting the pass-transistor logic SPL, a dedicated low power circuit technology. The software includes a logic synthesis function for pass-transistor-based macrocells and a macrocell placement function. Several new algorithms have been developed for the software, e.g. BDD construction. Some of them are designed and implemented for parallel processing in order to reduce the processing time. The logic synthesis function was tested on a set of benchmarks and finally applied to a low power CPU design. The designed 8-bit CPU was fully compatible with Zilog Z-80. The power dissipation of the CPU was compared with that of commercial CMOS Z-80. At most 82% of power of CMOS was reduced by the new CPU. On the other hand, parallel processing speed up was measured on the macrocell placement function. 34 folds speed up was realized. (NEDO)

    Followup research was conducted using a high-efficiency refuse-fueled power generation pilot plant for interpolating research and development results, improvement on refuse-fueled power generation efficiency, and for introduction and popularization of refuse-fueled power generation. Operation control and safety control were performed in compliance with the pilot plant operation program, when high-temperature high-pressure steam (500 degrees C, 100 atm) was stably generated for approximately 7,600 hours in this fiscal year recording a total of approximately 22,000 hours when counted from the beginning of the verification test. Plant operation data were examined and every part of the furnace was checked and measured while the furnace was at rest, and it was found that the plant satisfied the intended specifications as refuse-fueled power plant facilities. As for its environmental impact, it was confirmed that it fully satisfied the standard values for substances in exhaust gas, which involved soot and dust, sulfur oxides, nitrogen oxides, hydrogen chloride, and dioxins. Dioxins, in particular, were far below the most rigorous legal level of 0.1ng-TEQ/m{sup 3}N. In the test of superheater materials, long-term data covering three years were acquired. (NEDO)

    Discussions were given on a sterilizing effect of ozone on Fusarium bacteria in hydroponic culture, and its effect on components in the culture solution. In an experiment, dry air with O3 concentration of 3.5 ppm was sent into aqueous solution inoculated with Fusarium bacteria at a flow rate of 5 liters per minute. The Fusarium bacteria was sterilized nearly completely in about five minutes. No change was observed in pH, EC and dissolved oxygen concentration of the O3-treated culture solution. However, iron and manganese among the soluble components have been oxidized by O3 and precipitated, hence these components must be added after the O3 treatment. In spinach culture performed on a culture medium inoculated with Fusarium bacteria, ozone water containing dissolved O3 at 0.8 ppm was flown into a urethane foam medium and vegetable roots. This treatment has resulted in reduction of the number of strains occurred with a wilt symptom below that in the section flown with distilled water. The spinach has grown normally without showing an effect of the ozone water. 15 refs., 10 figs., 3 tabs.

    It is estimated that the woody biomass resources in Japan total 42.70 million t/y on a dry basis (indigenous production: 20.00 million t/y), which corresponds to 18.00 million t/y as oil. This project studies effective utilization of low-quality biomass resources now discarded, e.g., thinning materials and demolition woods, by reference to biomass utilization pursued in European and North American countries. The study activities cover the 3 areas of woody biomass wastes, current status of biomass utilization technologies in the overseas countries, and feasibility of introduction of the utilization technologies, after investigating necessity of abatement of the green-effect gases, current status of energy demands and policies, and woody biomass. Utilization of biomass resources for low-temperature heat purposes, which is the central issue in Japan, is not well established both technologically and politically. Moreover, the biomass resources are not exposed to price competition. Based on these premises, a total of 6 scenarios are proposed to promote utilization of biomass resources, including power/heat co-generation at a wood processing center, and dual firing at existing coal-fired boilers.

    It is well known that many kinds of hazardous organic compounds in incinerator exhaust gases. In this study, a simple sampling method to test mutagenicity on exhaust gases in flue and its extracting and its solvent converting methods by organic solvents were examined. In sampling 100 to 300 l at about 2 l/min in aspirating speed of the extract gases, the most of mutagenic substance were collected almost completely by condensed water and qualtz wool column. And, the collected materials into the condensed water could almost perfectly recovered by extracting the condensed water with about its one fourth volume of ethylacetate on vibrating once in 5 min., extracting the quartz wool column on flowing 20 ml of ethylacetate at the speed of about 3 ml/min., and others. After mixing such effluents and dewatering with about 5 g of sodium sulfate, they are evaporated out ethylacetate and resolved with 5 ml of dimethylsulfoxide (DMSO) to execute Ames mutagenicity test. As a result, more than about 3000 net rev./Nm{sup 3} of the mutagenicity was estmated on TA 98 strain. 9 refs., 5 figs., 8 tabs.

    Slag released from an electric furnace consists mainly of waste steel. There are two types of slag, namely, oxidized slag and reduced slag. Reduced slag, which is generally in the form of powder, is difficult to recycle as compared with oxidized slag. However, with a hydraulicity, some reduced slag is expected to be useful as hydraulic material. Test results obtained here show that the hydraulic properties of reduced slag powder can be improved by mixing it with gypsum and that the resultant mixture can serve to improve the prooperties of soft clay. Another study is made to determine the potential, as hydraulic material, of mixtures of reduced slag powder and waste gypsum material with a high gypsum content released from an oxidized titanium production process. The hydraulicity is found to develop as a result of the formation of a hydrate of calcium aluminate which is contained in the slag. Addition of water to the hydrate and gypsum cause the formation of ettringite, leading to an increased uniaxial compressive strength. These findings indicate that the above-mentioned mixture can be useful to improve the hydraulic properties of coal ash to be disposed of at landfill sites. 5 refs., 5 figs., 1 tab.

    Demonstrative operation was conducted of the super waste power generation system in which the low temperature steam generated in waste incinerator is raised in temperature using the combustion exhaust gas emitted after the power generation using another gas turbine for conducting the steam turbine power generation with high efficiency. The FY 2000 results were summed up. In the demonstrative operation, operation and data acquisition/analysis were conducted following the previous fiscal year by 25MW class gas turbine repowering waste combined power generation facilities (Takahama power plant). Further, four years after the start of operation, the secular variation was studied by disassembly/inspection of equipment. As a result of the operation, the thermal efficiency was approximately 35%, much higher than the existing waste power generation. It was verified that the power system was maintained by the same maintenance as that of the ordinary power system. Moreover, the important point of this system is that no special corrosion resistant materials are used and that the high-efficiency waste power generation was demonstrated by combining the existing equipment. It can be said that the super waste power system has high qualities for forming energy community as a regionally dispersed stabilized power source. (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)

    This paper is a generalized report in relation with the mine waste water treatment technology utilizing biotechnology, from among the promotion projects for research cooperation with China. Ferric iron (Fe{sup 3+}), which precipitates at low pH, is produced by utilizing bacteria which derives energy from oxidizing ferrous iron (Fe{sup 2+}) in the waste water, and the iron is precipitated and removed by using low-cost calcium carbonate as a neutralizing agent. Joint researches and developments have been carried out on selection of optimal kinds of bacteria, cultivation of bacteria oxidizing iron at high efficiency, optimal removal system of heavy metals in mine waste water, and recovery of useful resources. Japanese engineers were sent to sites in China, Chinese researchers were received in Japan, and pilot plants were operated and studied. For the purpose of proliferating and enlightening the result of the project, a seminar was held in Beijing in February 1998. In order for the achievements derived up to fiscal 1998 to be used in diverse fields, fiscal 1999 will carry out follow-ups, including assistance, for the voluntary researches performed by China. The follow-ups will also include confirmation on the state of testing the iron oxidizing bacteria technology, technical guidance, and analyses and discussions on the data. (NEDO)

    This paper reports the achievements in the Sunshine Project in fiscal 1988 in studies on the studies of the initial process in liquefaction. It is intended to identify the swelling phenomenon in coal particles in the coal slurry preparation and preheating processes, and change in the slurry viscosity associated with the heating. The slurry viscosity starts decreasing from around 300 degrees C at which the liquefying reaction begins, and decreases sharply at around 350 degrees C. Therefore, rise in the viscosity at temperatures below 300 degrees C is caused by factors other than the liquefying reaction. The rise starting at 100 to 120 degrees C is due to absorption of the solvent by coal. The rise starting at 210 to 260 degrees C requires further discussions. The equilibrium swelling ratio was measured on different types of coals by using the hydrogenated anthracene oil solvent. No coals swelled at 100 degrees C. The temperature of 200 degrees C largely divides coals into those swelling and those not swelling. At 300 degrees C, the coals were divided into those shrinking after largely swelling, those not swelling and those swelling monotonously. For consideration of the utilization as an auxiliary solvent, petroleum-based heavy oil was used to perform coal liquefaction to discuss effects of the solvent on the liquefaction rates. (NEDO)

    The removal treatment of free cyanide in waste water was tested by complexation with Fe(2) ion followed by alkaline chlorination and precipitation of residual iron cyano complex to study saving of sodium hypochlorite (NaClO) for alkaline chlorination. The complexation with Fe(2) ion was studied in batch treatment under the coexistence with zinc ion assuming plating waste water, while the relation between the complexation and effective chlorine consumption in alkaline chlorination was studied in continuous treatment. As a result, the effective chlorine consumption was greatly decreased by pretreatment, and a cyanic acid ion (CNO{sup {minus}}) concentration was also lower than that in conventional methods. In the case of free cyanide with lower initial concentration, the total cyanide concentration in final treated water offered sufficiently low values only by adding zinc salt, while in higher initial concentration, it reached 1 ppm or less through precipitation by adding a reductant together with zinc salt. 9 refs., 7 figs., 2 tabs.

    In this project, a pilot plant for mine wastewater treatment facilities using Thiobacillus ferrooxidans was installed at the Wushan mine in China to study the operation using the bacteria habitable in this mine. The project aims at establishing the mine wastewater treatment technology using the method of Thiobacillus ferrooxidans in China. The field survey and study in Japan were carried out. In the field survey, the technical guidance was given for incubation method, neutralization experiment method and analysis method of Thiobacillus ferrooxidans. In the study in Japan, one kind of bacteria to be used was selected in the 'selection test for the optimum kind of bacteria,' and a study was made which was titled 'Study of mine wastewater treatment using the method of Thiobacillus ferrooxidans which is suitable for the mine site.' In 'Study of the optimum removal of heavy metal in mine wastewater,' a table test of sulfide precipitation method was conducted on copper removal/recovery to make formation conditions of copper sulfide clear. The conditions obtained were reflected in 'Study of mine wastewater treatment by the method of Thiobacillus ferrooxidans which is suitable for the mine site,' and various conditions for bacteria oxidation process were studied. The paper surveyed characteristics of heavy metal and temperature of Chinese strains. Further, the basic data were acquired which contribute to the production of inorganic flocculants. (NEDO)

    R and D was conducted concerning intermediate processing technology for recycling mixed waste plastics, a technology for processing household waste plastics such as plastic containers and packaging into plastic pellets of suitable grain sizes, with fiscal 2000 results compiled. In the development of the element technologies, an air clutch structure was added that generates rotor slip when foreign matters were engaged, thereby unnecessitating pre-sorting work for locating and removing metallic foreign matters. Addition of an air separator and a sieving machine also helped to achieve a useful-plastics recovery rate of 75% or more in the PVC separation equipment. In the operation of a demonstration plant, a continuous operation was carried out in a three-shift 24-hour system for five days, with the data obtained. Further, waste plastics to which the Containers and Packaging Recycling Law was applicable were treated, resulting in the processing capacity of 0.51 t/h and the production capacity of 0.38 t/h, which both exceeded the target. In the evaluation of the intermediate processing system, the cost of waste plastics treatment turned out to be about 50,000 yen per ton in the case of a plant having a processing capacity of 6,000 tons per year and about 30,000 yen per ton in the case of a plant of 24,000 tons per year.

    The container and package recycling law is fully enforced starting fiscal 2000. Recycling obligation is placed also on plastic containers and packages discharged from households, excepting PET bottles for beverages and soy sauce. Therefore, it is required to establish an interim processing technology to process these materials into shapes easy for re-utilization and transportation, that is a technology to manufacture granules with adequate diameters. The purpose of this research is to develop the interim processing system technology. Design, fabrication and installation were performed on an interim processing system plant (a mixed waste plastic granule manufacturing facility) that can process annually waste plastics of 3,000 tons (0.5 t/h). The plant consists of the following four pieces of equipment: (1) a pulverizer, (2) a PVC sorting device, (3) a granulating device, and (4) a sizer. After the installed interim processing system demonstration plant has been trially operated and adjusted by each device, the whole plant was given the trial operation and adjustment to have verified that all the devices function normally. In addition, in order to evaluate economy of the waste plastics interim processing, the processing cost was calculated and the economic performance was evaluated preliminarily by using the rated electric power setting and trial operation data of each device.

    By operating the demonstrative plant for the preparation system to recycle mixed waste plastics and process them into such a shape that the transportation can be easier, conducted were the development of element technology necessary for the preparation and the evaluation study of process cost, economical efficiency, environmental effects, etc. The FY 1999 results were summed up. As to the operation of the demonstrative plant for the preparation completed in September 1999, the target waste plastic processing capacity of 3,000 t/y was expected to be achieved. Further, conditions were obtained for effectively separating/removing metal foreign matters such as iron and aluminum and heavy materials such as glass and plaster and for separating/removing chlorine resins such as PVC and reducing the chlorine concentration of the agglomerate to 2% or below. Concerning the development of the agglomeration technology by frictional heat, the target processing capacity of about 350 kg/h was expected to be achieved. In the plant assumed of the actual machine of process capacity of 6,000 t/y, the waste plastic processing cost was estimated to be about 70,000 yen/t. Moreover, the CO2 emission reduction amount of the agglomerate by coke substitution was quantitatively evaluated. (NEDO)

    An investigational study was made of the quantity of the specified freon remaining in the construction use heat insulating material, the rational method for the recovery/treatment, etc. As to the standardization of the method to analyze the remaining freon quantity, the tube furnace - GC method and the MS method were proposed, and the basic items that can be developed to JIS (Japanese Industrial Standard) were standardized. In the estimation of the remaining freon quantity, the actual state of the use of heat insulating materials was surveyed from the statistics on the start of construction work, survey of the heat insulating area in actual buildings and listening to heat insulation workers/cold store construction companies, etc. Further, the remaining quantity was analyzed of samples collected from various buildings nationwide and by years of completion. As a result, it was found out that, even in samples before 1995, HCFC is used in about 10% and that, in case of limiting to the specified freon (CFC), the freon remaining quantity was more than 1-4 wt% even after a lapse of 30 years. The paper arranged subjects on the freon recovery/treatment in each stage of the life cycle and the required conditions for technology/equipment. (NEDO)

    This promotion project on the cooperative research aims at developing technology to efficiently extract and recover valuable metals including in large quantity in tailings of ores in the Republic of Kazakhstan in consideration of the environmental harmony. The support study in Japan was conducted as follows. As to the Nikolayevska low grade ore, high leaching speed and high leaching rate by grain refining were made possible. The coarse grain was also possible of leaching if leached for a long time. The sulfide froth is possible of leaching in fine grain and in the temperature range of 50 degrees C. The Zhezkent tailings were possible of leaching with sulfuric acid, by aeration, and in the range of medium temperature. The sulfide froth was possible of leaching in fine grain and at temperature of 50 degrees C. After filtration/washing and regrinding, high sampling rates of bulk concentrate and pyrite concentrate were obtained by sulfide flotation by zanthate. The Zhezkent copper concentrate was tested on various factors such as grain size, temperature, and washing/no washing, to confirm effects of bacteria. In the pre-observation test on Au and Ag leaching, cyanogen leaching test was conducted using Cu leaching residue. About Cu, studied were leaching (vat leaching, flotation froth machine agitation (temperature increase, bacteria)), solvent extraction, and electrowinning. About Au and Ag, studied were cyanogen leaching and process of adsorption of activated carbon. (NEDO)

    A report is given here about the use of a newly-developed multi-channel surface wave data acquisition and processing system different from the conventional surface wave exploration device. This system enables the on-site pickup of a dispersion curve out of the multi-component surface wave data and, in the analysis of underground structure, performs the forward modeling and inversion. The system, furthermore, acquires and analyzes the data obtained from reflection earthquake exploration and constant microtremor observation. During a survey conducted along the highway from Port Ren-un to Xuzhou, China, estimation of the basement boundary was made by use of dynamite, and what was obtained agreed with the result of boring though with an error of 3m. In addition, this system could probe levels deeper than 100m using the instantaneous Rayleigh wave exploration method. This system and the conventional surface exploration device were compared in a soft ground in Fukui Prefecture, the former using a 10kg hammer and the latter using a 350kg exciter, when it was verified that the results produced by both techniques excellently agree with the geologic columnar section and changes in the N-value. 4 refs., 4 figs.

    Reflection exploration of earthquakes was conducted in the continental shelf off the north-west Australia, and a report is made concerning the processing of the acquired data. A GI gun was used as the vibration source, and a wave quite similar to a pulse was generated. Hydrophones were arranged with group intervals of 12.5m, and high-resolution field data were acquired. An analog low cut filter was used to suppress the large-amplitude swell noise attributable to sea conditions. A digital filter was designed for the purpose of eliminating coherent noises from other survey ships. At the ultimate stage the f-k filter was applied to each of the shot records, and the effectiveness was verified. The traverse line was as long as 6700km and therefore the design window was set relatively long at 2.0-4.0s in the residual static correction phase. It was found that this setup is effective in improving the continuity of the reflection surface. 5 figs., 1 tab.

    The comprehensive analysis was conducted of various data obtained in the geothermal development promotion survey conducted in the Kuwanosawa area, Yuzawa city, Akita prefecture, from FY 1998 to FY 2000. The geology of the Kuwanosawa area consists of the Pretertiary system and Quarternary system, through which intrusive rocks are recognized. Basement rocks are composed of the Paleozoic-origin crystalline schist and the Cretaceous-period granites which intruded into the schist. In the Kuwanosawa area, there were recognized no clear geothermal signs such as the discharge of geothermal fluids like hot spring, fumarolic gas, etc., places of high temperature and new geothermal alteration zones. The geothermal water of borehole N11-KN-1 is a low temperature/low CL concentration geothermal water which was stored in basement rocks, which is supposed to be the one conductively heated in the process of the meteoric water penetrating deep-underground. The geothermal system heat source in the Kuwanosawa area and the periphery is regarded as the relic magma which spewed out the volcanic rocks of Mt. Takamatsu-dake in the Quaternary period. However, the geothermal fluid included no components originating in high temperature volcanic emissions, and therefore, it is considered that the geothermal fluid was formed by the meteoric water conductively heated by volcanic heat source.

    As a part of the FY 1999 geothermal development promotion survey - Kuwanosawa area, the following were conducted and the results were arranged: ground surface survey (electromagnetic survey, analysis of numerical map), N11-KN-1 structure test boring survey, geothermal water survey, environmental effect survey, supplementary survey related to data processing, and comprehensive analysis. As to the reservoir structure, it seems that the area is low in water permeability from the results that there was seen little lost circulation at the time of drilling N11-KN-1 and that transmission coefficients in the water poring test indicated smaller values than those of the production well. In the underground temperature distribution, the temperature at a depth of 1,800m was 164.5 degrees C, which is lower than that in the neighboring Wasabizawa area. The geothermal water of N11-KN-1 does not have many dissolved constituents, showing alkalescence, which belongs to the Na-HCO{sub 3} type. As to the geothermal water of N11-KN-1, it seems that the meteoric water went down along faults and fractures, was stored in basement rocks and heated by heat conduction to form the geothermal water. In the Kuwanosawa area, there are seen very few geothermal signs on the ground surface, and a possibility seems to be small that high temperature and dominated geothermal fluids are active on a large scale.

    This paper describes the achievement in relation with the mine waste water treatment technology utilizing biomass, from among the promotion projects for research cooperation with China. Waste water is converted into ferric iron (Fe{sup 3+}), which precipitates at low pH, by utilizing iron oxidizing bacteria which use ferrous iron (Fe{sup 2+}) in the waste water as the energy source, and is precipitated and removed by using low-cost calcium carbonate as a neutralizing agent. Fiscal 1998 has performed eight site surveys with 47 persons in total. The main survey items are the study and guidance of pilot plant operation and the survey on measures to prevent occurrence of contamination by heavy metals in Wushan Mine. Additional site surveys were made at Dexing Mine and Yinshan Lead/Zinc Mine. Continued from fiscal 1997, consumables required for the pilot plant were purchased, and items of the bench-scale testing equipment used by Japan for domestic researches (an oxidation and neutralization testing equipment and a copper recovering and testing equipment) were transported to China. The operation research data of the pilot plant were put in order and analyzed. This paper summarizes the concept design of the shaft waste water treatment facilities for the north mine in Wushan Mine, and the surveys on measures for heavy metal contamination sources. (NEDO)

    The material distribution center is a facility to store the goods from a factory and to prepare to ship the goods in response to order from retail store. Recently, with multiplication of consumption market, multi-variety and less-amount of the goods, multi-frequency of delivery and time saving form order to delivery are required. As picking work to prepare the stored goods for each customer requires specially many man-hours out of the works in this center, time saving of working becomes an important problem. In this paper, for an object of the automatic picking system constructed by plural equipments and to execute picking of small goods for each order, the following two operation methods were proposed: (1) To define shelf sharing of the goods so that the picking requirement numbers for each picking hand may be uniform as well as possible in response to order distribution for each goods, and (2) to define treating sequence of order so as not to generate large difference in order treating times among each treating hand on operation in parallel. These operation methods were confirmed their total treating time saving by some experiments using actual ordered data. 7 refs., 8 figs., 6 tabs.

    The above-named survey had been scheduled to be conducted in fiscal years 1996-1998 for an approximately 10km{sup 2}-large area of Kokonoe-cho, Kusu-gun, Oita Prefecture. In fiscal 1996, surface surveys were conducted, such as geological and alteration zone surveys, gravity prospecting, and electromagnetic survey. In fiscal 1997, an exploration well (N9-KH-1: depth 2,222.0m) was drilled. Since the maximum temperature in the well was found to be so low as 78.5 degrees C, the survey was given up in the second year. The survey conducted at N9-KH-1 showed that deep-seated and shallow-seated ruptures developed there in the absence of aquicludes, and so it was inferred that it was a recharge area, as predicted by the temperature logging profile, with surface water flowing into the depth. The above showed that there was no deep-seated blind geothermal system which the survey was after. Since it was not likely that the shallow-seated geothermal system located in the southern part of the Mizuwake pass would be found expanding into the area of the current survey, it was decided that the survey not be carried forward to the following fiscal year.

    Corrosion of alloy proceeds in the conventional hydrogen absorbing alloy because the composing hydrogen absorbing alloy powder contacts with high concentration alkali electrolyte in the battery. Immersion into alkali aqueous solution and pulverization by metal fluoride compound of the electrode have been practiced to solve the problem, but internal resistance of the battery increases and the charge and discharge properties of the battery are deteriorated. This invention relates to a method in which hydrogen absorbing alloy electrode powder or the hydrogen alloy electrode whose main content is the said powder is contacted with alkali aqueous solution to increase the specific surface area of the hydrogen absorbing alloy powder, followed by its contact with pH3-6 acidic aqueous solution containing fluorine ions. As a result, corrosion resistance of the surface of hydrogen absorbing alloy powder after the treatment against high concentration alkali electrolyte is improved to elongate the cycle life. Salts of LiF, NaF, KF, RbF, and CsF or their hydrogen salts can be used as the supply source of fluorine ions. 3 tabs.

    In order to develop the evaluation methods for reappearing corrosion characteristics of coated steel sheets in a short time, acid rain composition and artificial acid rain composition for the accelerated test were studied, and the cyclic corrosion tests were conducted. The literature survey shows that the main ionic species present in acid rain are Ca{sup 2+}, Mg{sup 2+}, Na{sup +}, K{sup +}, NH{sub 4}{sup +}, SO{sub 4}{sup 2-}, NO{sub 3}{sup -}, and Cl{sup -}, of which the acid rain components are SO{sub 4}{sup 2-} and NO{sub 3}{sup -}, their equivalent ratio (NO{sub 3}{sup -}/ SO{sub 4}{sup 2-}) in the Far Eastern area being 0.2 to 0.3. Therefore, the solution specified by ASTM 1141 is diluted 30 times with water to prepare the base solution for the accelerated tests, where its acidity is adjusted with a mixed acid of NO{sub 3}{sup -}/ SO{sub 4}{sup 2-} = 0.2 to 0.3 (pH: 3.0 to 4.0). Two sets of preliminary cyclic corrosion tests were conducted, one involving acid rain spraying, drying and humidification in this order, and the other acid rain spraying, humidification and drying. Analysis of the test data indicates that difference between these test cycles in corrosion rate is within a deviation range caused by different testing tools. Therefore, the former condition is adopted as the basis for the accelerated tests, because of its smaller deviation caused by different testing tools. (NEDO)

    A report was made on the result for fiscal 1979 of the development of a coal solvent treatment and liquefaction plant. With the purpose of establishing a technology of making equipment for a coal liquefaction plant by a solvent treatment method, R and D were conducted on a solid liquid separation method and on the construction and operation of an experimental equipment having a scale of the maximum 1 t/day coal processing, providing technical data for the construction of an efficient coal liquefaction equipment. In studying the operation of a centrifugal separator, it was run using heating solvent, dummy slurry and coal extraction slurry, with no abnormality found in each equipment and with knowledge obtained of the separation state of the solid. The machine is capable of obtaining SRC of 0.2-0.3% low ash contents. Water operation was performed for the extraction processing device (agitation tank, heating furnace, compression pump, circulation pump, etc.) of the 1 t/day experimental plant and, as a result, a relation was confirmed between a water flow rate and pressure loss of the piping part. The detailed design, manufacture and installation were completed for a part (pulverizer, solvent tank, feeding pump, etc.) of the equipment for the coal pre-processing slurry making process and the extraction process, with a trial run implemented for adjustment and confirmation of the operation. The cold/hot continuous trial run by a solvent smoothly proceeded, proving the performance to be the same as the specifications. (NEDO)

    In this study, effects of variation of flow and accumulation of suspended solids (SS) on the performance of anaerobic/aerobic biofilm system were investigated through the laboratory test using synthetic wastewater and the field test using grey water. Effects of flow variation scarcely appeared on the time change of effluent quality in both cases where daily average hydraulic retention time (HRT) in anaerobic filter was 20h and that of aerobic filter was 6.7h. In the field test, however, removal rate of organic substances was lower (20-30%) than that of the laboratory test (90%), since SS content in grey water accumulated in the anaerobic filter which led dissolution of organic substances from accumulated SS, blocking, and short-circuit flow. Moreover, it was confirmed by the batch test that constituent of grey water has lower resolution for microorganisms and is more difficult to nitrate than synthetic waste water. 24 refs., 11 figs., 4 tabs.

    A verification plant operation study is conducted in cooperation with Thailand over wastewater treatment technologies for effectively decomposing and removing organic matters contained in foods plant wastewater and for recovering methane gas therefrom. The effort aims to transfer to Thailand anaerobic wastewater treatment technologies for recovering methane gas. For the 3-year research that began in fiscal 1998, a verification plant was installed at Cho Heng Rice Vermicell Factory Co., Ltd., located 30 kilometers west of Bangkok City. In the first half of verification plant related operation studies for fiscal 2000, the plant was kept in operation for the determination of the optimum operating conditions, and operation/maintenance technologies were transferred to Thailand. In the second half, plant operation was studied for by-passing the ultimate sedimentation tank of the factory. The results of activities are summarized into seven chapters of (1) outline of research cooperation project implementation, (2) outline of project implementation in fiscal 2000, (3) verification plant operation study, (4) automatic monitoring system construction, (5) technology disseminating activities, (6) study of support in Japan, and (7) subjects for future discussion.

    Effects of substrate concentration, specific surface area, and hydraulic loading, which are major factors influencing treatment efficiency in a submerged biological filter, were analyzed through the test with a special apparatus. In the test, the wall of the submerged biological filter was regarded as the contact material, and the specific surface area was changed by adjusting the sectional form of the filter. Using specimens from actual plant reservoirs, treatment efficiency for each case of three kinds of substrate concentration and hydraulic loading was measured. BOD removal rate was lower with smaller specific surface area. It was conspicuous particularly with higher BOD concentration in influent water. After the multiple regression analysis of the test results, the multiple regression equation to estimate BOD residual rate from three variates such as BOD concentration, specific surface area, and hydraulic loading was obtained. When 200mg l as BOD concentration and 50m{sup 2} m{sup {minus}3} as specific surface area were applied in this equation, the result almost agreed with the tendency obtained from data of actual plants. 6 refs., 4 figs., 1 tab.

Visits and investigations were also given on business entities in Thailand as to their design capability, quality control, delivery time control and maintenance capability. In designing the demonstration plant, the basic process combining the anaerobic treatment and aerobic treatment was adopted, and the detailed design was made according to the results of operation of the pilot plant in the past. This fiscal year has performed civil engineering construction composed mainly of RC structures, and fabrication and installation of devices and facilities ancillary to different structures. Devices were fabricated in Thailand whenever possible, with some parts being imported from Japan. (NEDO)

    The above-named survey had been scheduled to be conducted in fiscal years 1996-1998 for an approximately 10km{sup 2}-large area of Kokonoe-cho, Kusu-gun, Oita Prefecture. In fiscal 1996, surface surveys were conducted, such as geological and alteration zone surveys, gravity prospecting, and electromagnetic survey. In fiscal 1997, an exploration well (N9-KH-1: depth 2,222.0m) was drilled. Since the maximum temperature in the well was found to be so low as 78.5 degrees C, the survey was given up in the second year. The survey conducted at N9-KH-1 showed that deep-seated and shallow-seated ruptures developed there in the absence of aquicludes, and so it was inferred that it was a recharge area, as predicted by the temperature logging profile, with surface water flowing into the depth. The above showed that there was no deep-seated blind geothermal system which the survey was after. Since it was not likely that the shallow-seated geothermal system located in the southern part of the Mizuwake pass would be found expanding into the area of the current survey, it was decided that the survey not be carried forward to the following fiscal year.

    The research cooperation project on a technology to treat well waste water by utilizing biomass has used as the object the well waste water from the north mine in the Wu Shan mine in Jiangxi Province. The research included surveys on properties of the well waste water from the subject mine by means of the site survey, discussions on treatment conditions based on studies in Japan, and discussions on factors for designing a full size facility as a result of pilot plant operation research. The Japanese side has transported to Beijing the bench-scale testing equipment used for the studies in Japan (an oxidation and neutralization testing equipment and a copper recovery testing equipment). In the present follow-up project, supports were provided to the research and development activities performed voluntarily by the Chinese side by using the above bench-scale testing equipment through guiding the tests at the site and supplying consumables. Certain bacteria have capability to oxidize ferrous ions in the mine well waste water into ferric ions. Utilizing these bacteria results in sedimentation of iron oxides in lower pH zones than in the conventional method, making removal of heavy metals from the well waste water possible. As a result, such effects may be expected as reduction in chemical cost, and reduction of quantity of the produced sediments. (NEDO)

    Tehcnology for separation, recovery and fixation of CO {sub 2} was stated. In an absorption method used as a separating recovery method, CO {sub 2} in the waste gas is absorbed into a solution such as amine, heated and recovered. In an adsorption method, the CO {sub 2} is adsorbed by adsorbent such as zeolite, and recovered either by reduction of pressure or by heating. In a distillation method, the CO {sub 2} is distilled under low temperature and high pressure. In a membrane separation method, the difference of the membrane transmisison speed is used. In a fixation technology, the CO {sub 2} disposed into the ocean is liquefied by compression and forced into the deep sea through pipings. The liquid CO {sub 2} has greater density than water under 200 to 300 atmospheric pressure and clathrate is produced over the interface between the sea water and the liquid CO {sub 2} but the influence on the environment should be evaluated. As a means of recycling, synthesis of methanol or hydrocarbon with hydrogen contacting can be considered, and if such synthesis is used, fossil fuel can be reduced. As the source of the hydrogen, a method for combining the electrolysis of water and energy such as the sun and hydraulic power which do not generate CO {sub 2}. 16 refs., 3 figs.

    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)

    This research cooperation promotion project was implemented to develop techniques for preventing water pollution by waste water from pits in mines in China and thereby contributing to environmental preservation by studying to select optimum bacteria, culture the bacteria for high-efficient oxidation of iron, efficiently remove heavy metals from waste water, develop waste water treatment techniques with the aid of the iron-oxidizing bacteria, suitable for the mines in China, and develop techniques for recovering useful resources. The bio-aided waste water treatment process is a suitable method for treating waste water discharged from mining pits, in which ferrous iron present in waste water is oxidized with the aid of iron-oxidizing bacteria growing with ferrous ion as the energy source into ferric iron, which is precipitated at a low pH and removed in the presence of inexpensive calcium carbonate as the neutralizer. The pilot plant has been operating smoothly in a mode to treat waste water discharged from mining pits in Wushan Mine, almost satisfying the targets of treated water properties, i.e., pH: 0.5 or less, Cu: less than 0.5, Zn: less than 2.0, Pb: less than 1.0, Cd: less than 0.1, As: less than 0.5, Mn: less than 2.0, and SS: less than 70, all in mg/L except for pH.

    In terms of coal conversion reaction, the behavior of bituminous coal heated beyond a glass transition point was examined on the basis of pyrolyzed products, and the effect of an increase in proton mobility on promotion of coal decomposition was evaluated. In experiment, after Illinois bituminous coal specimen was heated up to a specific temperature in N2 or He gas flow at a rate of 5K/min, the specimen was directly transferred to a pyrolyzer for instantaneous pyrolysis. As the experimental result, the glass transition temperature of the Illinois coal specimen was calculated to be 589K from a differential scanning calorimetry (DSC) profile. From the pyrolysis result of the Illinois coal specimen heated up to 623K, the char yield decreased by 3kg as compared with that of the original coal, while the tar yield increased by 4kg up to 27kg per 100kg of the original coal. This tar increase was larger than that of cooled coal. These results suggested that the donation of hydrogen radicals to coal fragments is improved with an increase in proton mobility. 4 refs., 4 figs., 1 tab.

    Described herein are the results of the comprehensive analysis of the No.B-3 Kumaishi Area, investigated in the FY 1995 to 1997 period as part of the geothermal development promotion investigation project. The ground investigation project covers geological and altered band, geochemical, gravitational and electromagnetic investigations. The drilling investigation project covers the test drilling for the structural investigation, temperature logging, water injection and temperature recovery tests at the N7-KI-1, N7-KI-2, N8-KI-3, N8-KI-4 and N9-KI-5; core cutting investigation; hot water investigation at the 4 wells; environmental impact investigation; and supplementary investigations for determination of ages of rocks and alteration, and analysis of the substances contained in the fluid. The following conclusions are derived from the findings by the comprehensive analysis. The geothermal hot water in the test area came from seawater (fossil seawater) locally captured by the highly water-permeable strata (e.g., interfaces in the strata, and fractured strata) and underground water from rain water, heated by the conducted heat to around 200 degrees C at the highest. It is estimated that the center of the conducted heat is located in the eastern part of the Yagumo Area. (NEDO)

    For the purpose of confirming the existence of geothermal reservoirs, this survey was conducted as Survey B in the range of 30km{sup 2} east of Lake Ikeda at the south east end of Satsuma Peninsula, Kagoshima pref. from FY 1997 to FY 1999. By the geology/alteration zone survey, fluid geochemical survey, electromagnetic survey and gravity survey which were conducted in FY 1997 as surface survey, the following three were extracted as the areas which have great potentiality of geothermal resource existence: 1) area along the Yamakawa-Matsugakubo structure line on which calderas and explosion craters lie (north part); 2) area along the Takeyama-Tsujinodake structure line on which Ata central dome volcanic rocks lie (central part); 3) area around Kozukahama where the south wall of the Ata caldera extends in east-west direction (south part). In the survey after that, in north part, it was considered that aquicludes in clayey alteration zone were widely distributed around levels of 100m above - 200m below sea level and there existed geothermal reservoirs under the aquicludes. It was presumed that the mixed water of sea water and surface water was thermally conducted by heat sources of 300-490 degrees C and geothermal reservoirs of 260-270 degrees C were formed. (NEDO)

    Researches into organisms for their information processing, conducted in fiscal 1988 as part of a 'biological device research and development' project under the research and development system for basic technologies for the next-generation industry, are compiled into an article entitled 'information processing in neurons, and calcium ions.' The level of neuronal activity depends on changes in the level of nerve-membrane ion channel activity. Some kinds of ion channels are chemically activated (or inactivated) within the membrane. The phosphorylation of a protein ion channel is a typical case where an ion channel level is regulated chemically. In the muscarinic response of a neuron, a chemically operated ion channel plays an important roll relative to neuronal functions. In this response, a second messenger system in the neuron transmits extracellular information to the chemically operated ion channel. In this system, a calcium ion is one of important second messengers. (NEDO)

    Japan currently produces about six million tons of coal ash annually, whose effective bulk utilization to earth engineering materials is an important issue of technological development. A slurry may be made by mixing the following three kinds of materials: fly ash discharged from power plants exclusively burning dust coal (F), gypsum generated as a by-product in a stack gas desulfurizing process (G), and commercially available cement (C). The slurry would be called an FGC slurry taking the first letters of the materials. This paper presents the results of laboratory tests, in-situ execution tests and centrifuge model testing on engineering characteristics of soils improved by the FGC slurry when the slurry is applied to implementing the deep mixing method. As a result, a large number of findings were obtained including the following matters: the FGC deep mixing method makes it possible to improve ground beds having small deformation coefficient with the same accuracy as in the cement-based deep mixing (CDM) method at strengths lower than 5 kg/cm {sup 2} which is difficult with the CDM method, not to speak of strengths equivalent to that is possible with the normal CDM method; and development of a ground bed with improved strength is possible without being governed by quality and kinds of the fly ash. 1 ref., 23 figs., 5 tabs.

    Honjo mining area where investigations are conducted is hilly and has a complicated terrain with gas pipes buried in the ground just under the access road disabling the proper positioning of shock-generating large excavators or vibrators. Auger`s shallow hole shooting method is used in this survey to execute blastings at 639 points. In this method using charge depths of 4m, different from the conventional method using deeper charge depths (20-25m), surface waves prevail in the shot records giving rise to a new problem of removing them in the stage of data processing. The 2D filter that is a powerful tool in 2D data processing is not available in a 3D-survey where the tracing intervals are irregular in the shot records. In the effort of this time, a window length as a parameter in the direction of time is specified, and the F-X dip filtering method is employed in which any event that linearly continues beyond a certain number of traces in the said window is eliminated as a linear noise. It is recommended that the weighting function be changed in the direction of space since surface wave velocities are different at different locations. 1 fig., 1 tab.

    Described herein are the FY 1995 results of the No.B-3 Kumaishi Area investigation, conducted as part of the geothermal development promotion investigation project. The project covers the geological structure, geochemical, gravitational, electromagnetic, environmental impact and supplementary investigations. The following findings are obtained by the comprehensive analysis of the data. The Kumaishi Area is based on the sedimentary rocks and granite formed in the Pre-Ternary, which are unconformably covered by the strata belonging to Upper Oligocene of Ternary to Lower Pleistocene of Quaternary. The presence of NW-SE to E-W to NE-SW systems is suggested as the main fracture systems. It is estimated by the K-Ar method that the intrusion was formed in the 2.06 to 2.28Ma. The geochemical temperature suggests the presence of the fluid of 200 degrees C or higher as the deep hot water temperature. The resistivity structure generally indicates the NW-SE direction. Each stratum is confirmed by the test drilling for the structural investigation. The fluid motion model suggests possibility of hot water of high salt content, similar to that confirmed deep in the Yagumo Area, distributed deep in the Kumaishi Area. (NEDO)

    This paper describes the current actual conditions on treatment of bilge discharged from engine area and oily drain water from cargo area of tankers. Clean bilge among various bilges discharged from engine area such as vapor drain, fresh water, rainwater, seawater and condensed water is directly dumped into the sea after temporary storage in a clean tank. Oily bilge is produced mainly by mixing of clean bilge and leakage oil from main engines and various auxiliaries. Oily bilge is dumped into the sea under comparative monitoring of the bilge quality with the dumping standard by oil concentration monitoring and control equipment after the primary treatment in a treatment tank and the secondary treatment in a bilge separator. Oily drain water from cargo area contains water ballast for cargo oil tanks, wash water for tanks and lines, and bilge produced in pump room. The oily drain water is dumped under a specific condition. However, water ballast for specific ballast tanks is excluded from the oily drain water. 2 figs.

    A lot of efforts have been made traditionally for reducing the amount of water consumption in recycled paper industry. Several mills in Europe and the North America have succeeded in running the closed white water circuit that means to make the amount of water discharge be zero by returning the effluent water back. In this paper, the relevant factors that contaminate the white water in recycled paper mills are investigated. The accumulation of substances which provide bad effects on the paper manufacturing process and product quality is caused by the closed white water circuit in the recycled paper mills. The accumulated substances in white water include microorganisms, volatile fatty acids, salts, calcium, etc. Anaerobic/aerobic treatment is used as means for reducing the consumption of chemicals and energy and minimizing residues. The first biological in line treatment plant was utilized by Zulpich Papier in Germany and its result is satisfactory in aspects of production and product quality. 5 refs., 6 figs., 2 tabs.

    Recently, alkaline seepage water has been found in many landfill sites. Strong alkaline seepage water results from the use of alkaline agents, such as quicklime and slaked lime, for water removal from waste. In the present report, the neutralizing ability of different types of soil is studied to provide a method to neutralize seepage water by using soil covering at landfill sites. Results show that clay contained in soil is playing a major role in neutralizing alkaline seepage penetrating the soil. Clay generally has negative electric charges, suggesting that positive ions in alkaline water is neutralized after being replaced by hydrogen ions. Another major factor is the carbonate ion and carbon dioxide existing in soil, which precipitate and solidify calcium hydroxide as calcium carbonate to achieve neutralization. Investigations indicate that top soil comprising volcanic ash is useful as material for soil covering. 2 figs., 5 tabs.

    As a part of the survey of geothermal development promotion in FY 1992, chemical/isotopic analysis of fumarolic gas in the Yoshioka district was made to elucidate the underground geothermal structure in the west area of Mt. Aso in Kumamoto Prefecture. Items for analysis of fumarolic gas were 16 items including the temperature, concentration of non-condensable gas, CO2, H2O, CH{sub 4}, {delta}D(CH{sub 4}) and {delta}{sup 13}C(CO2). Items for analysis of condensed water were 9 items including pH, Na, NH{sub 4}, {delta}D(H2O) and {delta}{sup 18}O. As a result of the analysis, the main component of non-condensable gas of fumarolic gas was CO2, and the composition was similar to that of the fumarolic gas in the Yunoya/Tarutama district in the periphery. It was presumed that the origin and formation mechanism of fumarolic gas were also similar to those in the Yunoya/Tarutama district. It was presumed that the deep geothermal reservoir which is the source of vapor/gas generation was composed of the neutral or alkalescent geothermal water, and a possibility that the reservoir is connected with the deep geothermal reservoir in the Yunoya district was presumed from a viewpoint of geographical location.

    This is part of the state-operated 'geothermal energy development enhancement' project, under which a comprehensive analysis is conducted into the results of a survey of geothermal resources in existence in the Mount Kumbetsu area. The local geothermal structure is examined, and the Kumbetsu hot spring area, the Uebetsu river middle reach area, and the Unabetsu hot spring area are extracted as promising high-temperature supply areas. The Kumbetsu hot spring area and the Uebetsu river middle reach area lie on a heave positioned west of the Mount Musa/Mount Shitabanupuri fault. There is a distinguished bending in the zone of discontinuous resistivity, and, when geology is considered, it is inferred that there exists a geothermal fluid field formed by the Mount Musa/Mount Shitabanupuri fault running NNW-SSW and a fracture zone that runs across the fault. The two areas are located at spots where gravity gradient is sharp. It is concluded that, with the alteration zone, temperature distribution, etc., also taken into account, the Kumbetsu hot spring area is the more promising as a source of geothermal energy. The water of the Kumbetsu hot spring is of the Cl-SO{sub 4} type, 64.5 degrees C hot and neutral, and arises from the depth where water of meteoric origin is heated by heat conduction. The heat source is supposedly the magma reservoir whose eruption once formed Mount Unabetsu etc. (NEDO)

    Described herein are the FY 1996 results of the No.B-3 Kumaishi Area investigation, conducted as part of the geothermal development promotion investigation project. The ground investigation project covers geological and altered band, geochemical, gravitational and electromagnetic investigations. The drilling investigation project covers the test drilling for the structural investigation, temperature logging, water injection and temperature recovery tests at the N7-KI-1, N7-KI-2, N8-KI-3 and N8-KI-4; core cutting investigation; hot water investigation at the N8-KI-1 and N8-KI-2; and environmental impact investigation. The following conclusions are derived from the findings. The geothermal hot water in the test area came from seawater (fossil seawater) locally captured by the highly water-permeable strata (e.g., interfaces in the strata, and fractured strata) and underground water from rain water, heated by the conducted heat to around 200 degrees C at the highest. It is estimated that the center of the conducted heat is located in the eastern part of the Yagumo Area. The geothermal hot water was not heated to an extent to form the widely distributed convection systems, but arise in the form of separate, small-scale systems. (NEDO)

Synthesis of the target Si-Al-C-N-O-based compound succeeds in the presence of a solid catalyst, but it is a fine powder, and hence that of the massive compound fails. The commercial ceramic materials and new refractory materials, made on a trial basis, are evaluated for their resistance to corrosion using fry ashes collected from a commercial incinerator. These ashes are higher in melting point, more viscous, holding a larger quantity of attached slag and more corrosive than synthetic ashes. These materials are corroded acceleratedly as temperature increases to 1,200 degrees C or higher, more noted with the ceramic materials than with the refractory materials. Oxidation and melting characteristics of the molten slag affect corrosion of some materials. Use of the graphite-based material shall be limited to a section below the slag surface, where graphite is oxidized to a smaller extent. The MgO-based material is promising. The Al{sub 2}O{sub 3}-Cr{sub 2}O{sub 3}-based material is more promising than any other material developed in this study. Their bending strength before and after the corrosion test is measured at normal temperature to 1,700 degrees C, to investigate their deterioration by high temperature and corrosion. (NEDO)

    To establish the inhomogeneous solid combustion control technology, effects of the strong magnetic field on the solid combustion were examined. When applying the sufficiently strong magnetic field, it is possible to control the air flow in combustion field by utilizing the force applying to constituent oxygen with large susceptibility. Based on this possibility, combustion experiments of expanded polystyrene plates were conducted between the magnetic poles of electro-magnet having the maximum flux density of 1 T and the maximum magnetic field gradient of 0.5 T/cm. To observe the effects of magnetic field without the effects of natural convection, combustion experiments of acrylic sheets were conducted between the magnetic poles of electro-magnet having the maximum flux density of 0.6 T and the magnetic field gradient of about 0.1 T/cm under the microgravity conditions between 10{sup -4} and 10{sup -5}g using a microgravity test facility. Consequently, prospective combustion results could be obtained, in which the force of flame received from the magnetic field is almost equivalent to the buoyancy of flame. It was demonstrated that combustion can be controlled by the magnetic field. 1 ref., 3 figs., 1 tab.

    Activated carbon impregnated iodic acid (deodorant D) was developed as a new deodorant. Deodorization performance of deodorant D as well as three kinds of commercial activated carbons (deodorant A, B and C) was tested for odors originating from the kitchen wastewater treatment facilities of one commercial building. The odor exhausted from this facility was medium concentration between 422 and 31,620. The main odorous compounds were hydrogen sulfide (0.076 to 15.7 ppm) and methyl mercaptan (not detected to 0.081 ppm). The hydrogen sulfide contribution to the odor concentration was about 90%. The main apparatuses from which the odors were originating were the raw water tank and the pressurized flotation tank. The total odor emission rate was between 10{sup 4.9} and 10{sup 5.7} Nm{sup 3}/min. For the performance test for deodorants, fixed bed adsorption experimental equipment was used, and the breakthrough time of odor concentration and hydrogen sulfide were used as indexes. Correlation between the contact time and the breakthrough time was observed for all of the deodorants. For a contact time of 0.5 sec, the breakthrough times for odor concentration were D>C>B>A, and the breakthrough times for hydrogen sulfide were D>C>B>A. Effectiveness of activated carbon impregnated iodic acid was recognized. 11 refs., 7 figs., 7 tabs.

    As part of the geothermal development promotion survey, the comprehensive analysis was made on the survey of the existence amount of geothermal resource in the Mt. Musadake area, Shibetsu county, Hokkaido, which was conducted in FY 1997. In the surface survey, the following were carried out: survey of geology/alteration zone, age determination of rocks, alteration age determination by thermoluminescence method, geochemical survey (hot spring gas, hot spring water), gravity exploration and electromagnetic exploration. In the survey of environmental effects, survey of flora/fauna and survey of hot spring variations were made. The results of the analysis were outlined as follows. The geothermal system in this area seems to be controlled by the Mt. Musadake - Mt. Shitabanupuri fault, folding zone along the fault and Graben-state structure extending southeast of the zone. At deep underground, the existence of the deep geothermal water forming geothermal reservoirs is presumed, and the deep geothermal water seems to be helped by the thermal conduction and volcanic effluences from the magma reservoir related to a series of volcanoes, centered on Mt. Musadake that is regarded as heat source. The geothermal water has a temperature of over 250 degrees C and a high Cl concentration. (NEDO)

    This survey studies possibilities of geothermal resource existence by checking the presence of high temperature anomaly by a wide-area survey with the aim of extracting the area for Survey B and Survey C to be conducted. The area for survey is an area of approximately 300km{sup 2} including Shibetsu town, Shibetsu county, and Rausu town, Menashi county, which are located east of Hokkaido. Conceptual models of the geothermal system in this area which are thought of from the results of the survey are as follows. It is assumed that heat source exists deeply in Unabetsudake (Mt. Unabetsu). From the fact that the K-Ar method age of the ejecta is 0.5Ma and the TL method age of the rate. (NEDO)ch the position of drilling of the well for survey of heeffective as heat source. It is thought that the water of hot spring/mineral spring came to indicate various spring qualities by mixture of meteoric water and fossil seawater at various ratios. The fossil seawater and old meteoric water are being heated by thermal conduction. The mixture with the original water of Kawakita hot spa is recognized in Shibetsu Kanayama hot spa. It is assumed that the high temperature area exists mostly in Unabetsudake, but the spread does not reach the position of drilling of the well for survey of heat flow rate. (NEDO)

    A comprehensive analysis was conducted into the results of a survey on the state of existence of geothermal energy resources in the Musadake region, Shibetsu-gun, Hokkaido. The region was volcanically active in the period from the Neogene period into the quaternary, with some volcanos still active even today. The geological structure on the whole is characterized by the Musadake/Mt. Shitabanupuri fault which is the major structure running NNE-SSW and having a folding structure. It is inferred that Musadake is the heat source responsible for the underground temperature distribution in this region. The maximum temperature of 274 degrees C is recorded at borehole N11-MD-3 in the northeastern part of Musadake, and the temperature falls rapidly as the distance from the borehole increases. Ejection of geothermal fluids is observed at boreholes N11-MD-3 and N11-MD-4. It is inferred that the deep-seated geothermal water is of the neutral Cl type with Cl concentration estimated at approximately 12,000 mg/liter. Steam composition is characterized by a gas concentration level that is as high as 3-4 vol.%. The gas is composedly mainly of CO2 and contains some hydrocarbons. Fluids in this region are classified into water mixing into deep-seated geothermal water and groundwater originating in meteoric water. (NEDO)

    The result of the data processing (Phase 1) and the result of the 1998 survey carried out for the Tsujinodake area, Kagoshima Prefecture, were subjected to a comprehensive analysis, and the state of existence of geothermal resources in this area was compiled into a report. In fiscal 1998, structural boring (N10-TD-1), thermal water examination, seismic exploration, environmental impact assessment, fluid inclusion examination, and rock dating were conducted. Some findings obtained from the comprehensive analysis are mentioned below. In the vicinity of structural borehole N10-TD-1, fluids move along geological boundaries and in permeable layers in the horizontal direction, with an aquiclude serving as a border. At levels deeper than 980m, there flows a mixture of seawater heated to approximately 135 degrees C by thermal conduction and water originating in Lake Ikeda. Still deeper, water from Ikeda Lake flows in and lowers the temperature. It is suggested that there may be a sharp and abrupt rise in temperature at levels deeper than the cooling region near the bottom of structural borehole N10-TD-1. It is inferred that the magma reservoir that produced the Tsujinodake lava is small as a heat source or that it has not yet formed a high temperature geothermal system shallow in the ground. (NEDO)

    This paper describes photosynthetic function of plants, and CO {sub 2} fixing function of marine organisms. Among the photosythetic reaction systems, the C {sub 3} type reaction carries out CO {sub 2} fixation using the Calvin cycle, and takes out the carbon dioxide out of the system through enzymatic reactions of 3-phosphoglycerate {yields} fructose-6-phosphate. The C {sub 4} type reaction has a special cycle to supply CO {sub 2} to the Calvin cycle, i. e. C {sub 4} dicarboxylic acid cycle. The CAM type reaction enables the photosynthetic type to be converted according to variations in the growing environment. The majority of the surace agricultural crops are from C {sub 3} plants, of which yield may be increased when grown in a high CO {sub 2} atmosphere. On the one hand, gene engineering may make possible breeding of plants having high CO {sub 2} fixing capability. In the area of marine organisms, lime algae growing in clusters around coral reefs form and deposit CaCO {sub 3}. Reef creating corals have symbiotically in their stomach layer brown algae having photosynthetic function to build CaCO {sub 3} skeleton. The corals calcify algae quickly and in a large quantity, hence play an important role in fixing underwater CO {sub 2}. 2 tabs.

    Laser surface melting treatment used for the improvement of intergranular corrosion resistance of sensitized austenitic stainless steel weld metal was studied. As a result, it was revealed that as compared to untreated material, sensitization was improved widely and intergranular corrosion resistance was improved to a level of base metal when laser surface melting treatment of sensitized weld metal was carried out. Further, sensitization effect at a condition of laser traveling velocity of 0.00167m/s was slightly insufficient compared to that of laser traveling velocity above 0.00833m/s. This phenomena was caused due to the existence of {delta} ferrite that accelerates the precipitation of Cr carbides inside the laser treatment portion and together with this, the Cr carbides are precipitated in {delta}/{gamma} grain boundary due to the effect of laser heat cycle with insufficient cooling velocity and this has caused desensitization. 16 refs., 13 figs., 3 tabs.

    Survey/study were conducted of viability of an idea of the high efficiency power generation that combinedly use RDF from the refuse generated in Shizuoka/Yamanashi/Nagano prefectures and LNG from the LNG base in Shimizu City, Shizuoka Prefecture. In the survey of raw materials for RDF, the present amount that can be supplied to RDF power generation was estimated at 280 t/d in RDF and 4,300 Kcal/kg or more in heating value. As to the RDF/LNG combination power generation, combinations of RDF200t/d + 25MW (capacity of gas turbine power generation) or RDF200t/d + 70MW seem to be appropriate. And, 30% or more of RDF power generation efficiency is made possible. In the study of economical efficiency, expenses born by local governments were calculated supposing that the difference between the unit price of power selling and that of power generation in power generation is born by RDF suppliers. As a result, the share becomes approximately 8,600-12,000 yen/refuse t in 15-year operation, and was found lower than that in the existing small-/medium-scale refuse incineration treatment. The combustion flue gas associated with the power generation business becomes approximately 300,000 Nm{sup 3}/h. The gas turbine fuel is natural gas, and RDF is good in combustibility. Therefore, the effect on the environment is expected to be small. (NEDO)

    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.

    High efficiency power generation, which is useful for promoting the environment-friendly type energy and coordinated community, is investigated by combining a steam turbine power generation system using the PS-RDF (paper sludge-refuse derived fuel) and a gas turbine (GT) combined cycle. Industrialization plan for processing PS in low cost has been made to ensure the profitability by participating the wholesale power supply under the law of electric power industry. This combined system is similar to the so-called super power generation using municipal garbage, but the lower temperature of steam from GT waste heat boilers (WHB) is super-heated by the flue gas from RDF boiler, which is called advanced power generation system (A.S.S.). The total power generation capacity is 149,000 kW, which consists of three 35,000 kW units of GT and one 44,000 kW unit of steam turbine. When comparing the combined system (A.S.S.) and usual one with the independent installation of the RDF steam power generation system and a GT combined cycle, the A.S.S. provides the repowering efficiency of 7,600 kW output with exactly the same quantity of fuel input as usual one. 71 figs., 31 tabs.

    Experimental researches were made on rice husk charcoals processed to be used as culture media for hydroponics. Rice husk charcoals with a size of 1 mm or larger retaining the original shape of the rice husk, and with a size of smaller than 1 mm were made for use in the experiment. In the culture media made of these rice husk charcoals, the charcoal with a particle size greater than 1 mm had more air portion than water portion at 6 cm above the water level, and the charcoal with a particle size smaller than 1 mm had poor air permeability. According to the result of immersing the rice husk charcoal in a culture solution, phosphoric acid ion and manganese in the solution decreased by about 35% and calcium by about 10% in the duration of 120 minutes, as a result of having been adsorbed into the rice husk charcoal. On the other hand, chloride ion increased by about 80% and potassium and iron by about 30%, because of having been dissolved out from the charcoal. In cultivating spinach, butterhead lettuce and radish in the rice husk charcoal culture media, the culture medium with charcoal smaller than 1 mm resulted in harvest reduced by about 75% in spinach, and about 10% in butterhead lettuce. 15 refs., 13 figs., 11 tabs.

    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 technology is developed to perform high-efficiency power generation by generating high-temperature and high-pressure steam stably by burning general wastes and combustible industrial wastes as fuel. This paper describes summary of the achievements in fiscal 1998. Corrosion tests were performed on over-heater materials under steam condition of 500 degrees C and 100 kg/cm{sup 2} by using a hot model. It was verified by the tests that the corrosion environment around an external heat exchanger is milder than that with an external stack. A circulation fluid bed was simulated from operation data, and a prospect was obtained on steam conditions required for the high-efficiency power generation. In order to elucidate the corrosion mechanism, discussions were given on deposited ash properties, corrosion characteristics and stress. Elucidation was made on a discharge chamber structure most suitable for removing dioxins and NOx by using a waste gas treatment process that uses plasma generated by discharge. A concept design was made. The economic effect of the system is equivalent to that of the activated carbon blow-in process, whereas a waste gas treatment system was nearly completed. As a result of the pilot plant test, the power generation efficiency is estimated to be 30% in a scale of 1200 tons per 24 hours. A demonstration test revealed that dioxin emission was far below the regulation value. An optimal system was also discussed. (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.

    The refuse-derived fuel (RDF) has been holding public attention not only as the energy resource of stable high calorific value for local energy development, but also as the effective method for waste treatment. As one of the effective utilization methods for waste treatment, this investigation was conducted to industrialize and establish the RDF power generation system, in which power generation and ash treatment are integrated in Tochigi Prefecture which is located inland. The base supply type was adopted as a way of operation from the menu of the electricity wholesale project of Tokyo Electric Power Co. and its rate of operation is 80 percent a year. Then, the fluidized bed combustion method, a dry exhaust gas treatment method, and continuous electric melting furnaces were decided as the RDF power generation system. According to this system, it is possible to obtain 26 percent gross thermal efficiency by conventional generation facilities. It was estimated that the expenses reduction for 15 years will be 17.6 billion yen compared with the ordinary combustion system. Also, the following effects can be expected; the reduction of CO2 emission, improvement of energy efficiency, and the extension of life of landfills capacity. 36 figs., 51 tabs.

    The R and D project has been implemented for small-size gasification melting furnace and exhaust gas treatment system to develop a small-size industrial waste incineration system capable of coping with the new standards, which simultaneously incinerates the waste and treats the resultant ashes, to control evolution of dioxins and, at the same time, recover heat at high efficiency. The studied items include controlling evolution of dioxins by removing salts of heavy metals (e.g., copper) and quenching exhaust gases in a ceramic heat-exchanger, and development of the materials for filters and high-temperature mist separators serviceable under severe conditions. For building the systems, the plant comprising a pyrolysis/gasification melting furnace, high-temperature dust collector and ceramic heat exchanger is designed, constructed and continuously operated for an extended period. As a result, it has been confirmed that the system can be operated stably, evolution of dioxins can be controlled, self-heat recovery type system can be developed, and dust can be reduced in volume.

    Ti-6Al-4V allow was solution treated and aged (STA) in air, and the effect of degraded layer on static tensile properties and fatigue behavior was studied. Also, influence of surface finishing on fatigue strength was studied. Degraded layer formed with 0.75mm thick hardened layer has been formed below extremely thin TiO2 scale. Static tensile properties and fatigue behavior are not influenced by the hardened layer. The hardened layer formed below embrittle layer has smaller hadenening scale, and has shown no structural change with the core. Even for an embrittle layer of about 10[mu]m thickness, the ductility and fatigue strength have reduced significantly. The static strength has been improved about 20% with the complete removal of embrittle layer. The fatigue strength of the receiving material has been greater in the case of mechanical polished finishing using NO.1500 emery paper and diamond taste of 1[mu]m compared to electrical polishing. However, the fatigue strength has been lower in the case of mechanical polished STA material compared to electropolished material. 8 refs., 18 figs., 2 tabs.

    As a part of the FY 1997 survey of the promotion of geothermal development, the gravity filter analysis was made of the data processing in the Tsujino-dake area of Kagoshima prefecture, and the results were summarized. The geothermal fluid used in the Yamagawa geothermal power plant has the residual magma brought by activities of volcanic rocks of the Ata central shield volcano as heat source, and the fracture system and deep intrusive rocks are reservoirs. A small scale of gravity anomaly area is located, and it reflects high-density volcanic rock masses which are distributed on the earth surface or shallowly under the ground. The ridge stretching from Kiyomi-dake to the Narukawa tunnel and the ridge connecting Kuze-dake and Tsujino-dake are in the high-gravity area and reflect high-density rocks in the shallow part and deep part. There is a possibility of the existence of the fracture system in the high-density deep basement. Calderas continue close to the south of the high-gravity ridge stretching from the Kiyomi-dake to the Narukawa tunnel, and the fracture system which brings the eruption of volcanic rocks of the Ata central shield volcano and the fracture system forming caldera exist in parallel. From the aspect of the geothermal structure, a consideration was made of rock layers which possibly compose the rise of high-density basement in the deep part near the Tsujino-dake. (NEDO)

    This paper describes the achievements in the Sunshine Project in fiscal 1993 in the investigation for coal type selection. The investigation is purposed to elucidate the status of existence and resources of coals as the raw material for coal gasification and liquefaction, the coal quality features, and the gasification and liquefaction characteristics. The results will be used as the fundamental materials for technological development. Discussions will also be given on the coal applicability to the composite gasification power generation system in which liquefied residue generated in the process are mixed with the supplied coal. Coal quality analysis and a liquefaction test under the standard condition were completed on 389 test samples composed of 136 kinds of coals produced in Canada, Australia, the U.S.A., China and Indonesia. Coal types were enumerated according to the oil yield. A gasification test was performed on the specific gravity separated coals of Chinese coals to discuss the effect of change in the ash amount on the gasification characteristics. A partial coal combustion test revealed that fuel ratio, oxygen partial pressure, and oxygen molar fraction parameters affect the combustion characteristics. The micro-gravity field is effective in discussing the combustion characteristics of particulate groups of dust coal. A coal oxidizing test was performed, wherein oxidizing characteristics and spontaneous ignition performance were estimated successfully from temperature rise of heat stored in coal. The coal type matrix data were prepared. (NEDO)

    A method of estimation of processing time for a management function is proposed to test system performance. This method utilizes characteristics of message passing between managed objects to recognize all over the systems. Estimation of processing time is proceeded with following steps. (1) analysis of message flow: with design information, message patterns are set and the number of messages to be sended and received are counted. (2) measuring processing time of each message type: we developed programs to measure processing time of sending and receiving messages. Using this programs, message processing time for each message type is measured. (3) calculating total system processing time: managing system processing time and managed system processing time are calculated. Total system processing time is derived from those. This paper also shows the applying proposed method to SDH fault detection function, which have two different processes: all event process, event and log process. This resulted in 2:1 processing time on a case of fiber cut off for managing two SDH equipments. (author)

    Survey was made on residential waste treatment in Shanghai city. Shanghai city with nearly 13 million registered residents produces on average 10,000-11,000 tons/day residential solid wastes. Such wastes are basically disposed by land filling. A landfill site has a current disposal capacity of 7,500 tons/day, and is scheduled to be expanded up to 9,000 tons/day. Problems of waste disposal in Shanghai city are as follows: transportation of wastes collected in the city by trucks, transportation through transit stations to the landfill site by ships, and high disposal cost. Shanghai Environmental Sanitation Bureau is pursuing researches on recycling of wastes, reduction of wastes and harmless treatment in place of conventional land filling. As the survey result, adoption of complete separate collection of wastes is basically important, and application of the latest technologies such as combustion treatment for every waste, heat use, gasification fusion furnace, and RDF (refuse derived fuel) for coal-firing boilers should be considered. 86 figs., 18 tabs.

    A geology/alteration zone investigation and gravitational probing were carried out, with the results summarized, for the purpose of elucidating the structure of geothermal reservoir structure in the Kuwanosawa area. The investigation was implemented in the southeast part of Akita prefecture including Yuzawa city and Ogachimachi during the period between June 9 and August 31, 1999. The results were as follows. The geology of the investigation area consists of granite, as the base rock, and the covering Doroyu layer, Minasegawa layer, Sanzugawa layer and intrusive rocks in the Neo Tertiary system as well as Kabutosan layer and volcanic rocks in the Quaternary system. No wide area alteration zone existed, while vein-like alterations and hydrothermal veins along cracks were recognized, with the fluid inclusion homogenizing temperature showing 240-260 degrees C, which presumably indicates the existence of local hydrothermal activity until comparatively recently. The geothermal structure of the subject area is very likely dependent on thermal conduction from a deep thermal source existing in the Wasabizawa district. In the underground depth, it is inferred that a hydrothermal system is formed in the NW fault structure, lower part of cracks accompanying NS hydrothermal vein, and in the NNW/NE structures inferable from the gravitational probing.

    In order to improve the tribological properties of magnetic tape with Co-{gamma}-Fe{sub 2}O{sub 3} fine particles against a magnetic head, the silica coating onto the surface of Co-{gamma}-Fe{sub 2}O{sub 3} particles in aqueous slurry is investigated experimentally, and the kinetic friction coefficient of magnetic tapes prepared using the coated particles is measured. By this silica coating, the amount of myristic acid absorbed on the Co-{gamma}-Fe{sub 2}O{sub 3} particles tends to decrease and the kinetic friction coefficient of the magnetic tapes can be reduced from 0.4 to 0.2 because of the increase of the effective amount of myristic acid working as the lubricant when the magnetic tape is moving. Since the magnetic properties and the dispersibility of Co-{gamma}-Fe{sub 2}O{sub 3} pigment in the magnetic lacquer are not degraded by the silica coating, this coating method is expected to result in magnetic recording media with both good magnetic and low friction properties.

    A joint research has been carried out in the Republic of Kazakhstan on a technology to extract and recover efficiently the valuable metals (copper, gold, silver and others) contained in ore wastes in large quantity, with considerations given to the environment. This paper summarizes the achievements in fiscal 2000 being the last fiscal year. This joint research has performed researches on the processing technology and processes, and on the operation research by using a pilot plant, using low-grade ores in the Nikolayevska Mine and ore wastes from the Zhezkent Mineral Dressing Mill as the objects. As a result of the researches, the following matters were discovered: if the ore wastes are used as the starting materials in the copper recovering process using the chemical leaching process, the copper price of $1,800 per ton is the breakeven point; economic effect is enhanced by grinding the starting materials into finer particles, adding a zinc recovery process, and recovering gold by using cyanogens; and this pilot plant is pollution free, and easy in maintenance and control. These processes were concluded effective in reducing the efficient waste ore processing and environmental cost being the environmental problem in Kazakhstan. (NEDO)

    This paper reports the fluid inclusion test in the Tsujinodake area in fiscal 1998 for the survey on promotion of geothermal development. The fluid inclusions were classified into three types: those with the maximum value or the average value of the homogenizing temperature agreeing nearly with the saturated boiling curve, those with the homogenizing temperature showing the interim temperature between the present well temperature and the saturated boiling curve, and those agreeing nearly with the present well temperature. It is presumed that the bed temperatures in depths of 1,125.30 m and 1,427.50 m have changed very little since after formation of the present circulating and flowing systems of geothermal waters until now. In contrast at the depth of 1,691.75 m, the bed temperature was estimated to have fallen slightly from that in the most active period of the geothermal water activities. As a result of the rock age measurement, it is estimated that, in the Nansatsu bed groups distributing around the N10-TD-1 well, the temperature has fallen gradually after having been subjected to hot water alteration actions at higher than 200 degrees C, and cooling has taken place down to 200 to 250 degrees C as the fission track date temperature of zircon in the relatively late period (about several hundred thousand years before). There should have been no thermal change that affects the age measurement up to now since then. (NEDO)

    This paper reports an image processing analysis of combustion for a high-pressure direct injection diesel engine on the effects of air swirl and injection pressure upon combustion in the diesel engine. The paper summarizes a method to derive gas flow and turbulence strengths, and turbulent flow mixing velocity. The method derives these parameters by detecting movement of brightness unevenness on two flame photographs through utilizing the mutual correlative coefficients of image concentrations. Five types of combustion systems having different injection pressures, injection devices, and swirl ratios were used for the experiment. The result may be summarized as follows: variation in the average value of the turbulent flow mixing velocities due to difference in the swirl ratio is small in the initial phase of diffusion combustion; the difference is smaller in the case of high swirl ratio than in the case of low swirl ratio after the latter stage of the injection; the average value is larger with the higher the injection pressure during the initial stage of the combustion; after termination of the injection, the value is larger in the low pressure injection; and these trends agree with the trend in the time-based change in heat generation rates measured simultaneously. 6 refs., 14 figs., 2 tabs.

    To offer remote processing of the conventional customer service and advanced customer service using information network, customer side equipment, power controller, was manufactured as a trial. For inspecting the power meter by remote processing, watt-hour meter placed outside was moved into house, to integrate an indoor distribution board consisting of a breaker for contract, earth leakage breaker and branch breaker by adding functions of communication, equipment monitoring and control and functions of display and operation. When detecting fault, installed CPU (central processing unit) or DSP (digital signal processor) stops its operation and each breaker keeps its state as before the fault. Thus, there is no problem for power supply. This system has a battery to maintain and operate at least the display function in the case of outage. Advanced customer service functions could be added without a large cost. To increase understanding of customers concerning electric power saving and electric power itself, consuming electric energy and current are displayed at each branch. Outage of the whole house can be avoided by the rapid detection and removal of the earth leakage branch line. 14 refs., 14 figs., 3 tabs.

    The paper studied the international standardization of the chemical analysis method and glow discharge optical emission spectrometry. Chemical composition and coating thickness (g/m{sup 2}) of 14 kinds of specimens including alloy coatings and organic coating with zinc and aluminum as base were analyzed by the above-mentioned methods to examine the relation between the both. As the chemical analysis method, used was inductively coupled plasma atomic emission spectrometry. To study the relation between the methods, it was found to be necessary to recognize morphology at the boundary between the coating and base steel using, for example, scanning electron microscope (SEM) and electro-probe micro-analysis (EPMA). To measure traceability of the analysis method, with the chemical analysis method as a judgement method, it is necessary to make reference materials by coating materials, to use the calibration graph confirmed by the materials and to adopt the glow discharge optical emission spectrometry. On the basis of such way of thinking, drafts were worked out for the international standardization of the chemical analysis method and glow discharge optical emission spectrometry. 7 refs., 117 figs., 33 tabs.

    This paper describes development of a technology to decompose dioxins in incineration fly ash. Experiments were carried out during fiscal 1998 by using a bench-scale plant and a laboratory-scale plant of the installed supercritical water treatment equipment designed and fabricated in fiscal 1997. With the bench-scale plant, operation methods were discussed, whereas high temperature and pressure operation of 25 MPa and a temperature internal to the reactor of 350 degrees C were achieved. An alcohol combustion test and a preliminary slurry delivery test were also performed. With the laboratory-scale plant, operating methods were discussed, and combustion tests were carried out by using different organic matters as fuels for the supercritical water oxidation reactor. Investigations were executed on the effects of reactive operation parameters on organic matter decomposition rates, produced gas compositions, and reactor wall temperatures. The intensity of hydrogen bond between solvent and water has decreased to almost half of the normal temperature and pressure water in the vicinity of the critical point. However, strong interaction still remained in terms of per unit density. A portable equipment (650 degrees C and 25 MPa at the maximum, and standard treatment quantity of dry fly ash of 1 kg/h) was operated for demonstration. Operation methods and organic matter decomposition characteristics were identified in alcohol operation and slurry operation. (NEDO)

    This paper describes the result of an investigation by testing on re-utilizing the used desulfurizing agent discharged from a thermal power plant as a sludge disposer and a deodorant. The used desulfurizing agent used in the test is a nearly neutral substance composed mainly of SiO{sub 2} and CaSO{sub 4}. The paper describes that the tested agent has a character to solidify when added with water, and the solidified substance made from the agent added into a sludge is nearly neutral and usable in the similar manner as in the commercially available sludge solidifying materials. The paper also reports that in a field test for applying this tested agent to cover the sludge surface, a marked effect of improving water quality was recognized, including the increased water transparency. It also states that the tested agent absorbs ammonia actively, and that as a result of investigating its applicability as a deodorant for pet excreta odors, the agent can be handled more easily than the commercially available deodorants and has a deodorizing effect equivalent to or better than them. 4 refs., 7 figs., 6 tabs.

    A technology is developed which treats pickle maker's wastewater containing highly concentrated saline contaminants by resorting to a combination of bacilli and membrane treatment. A 9m{sup 3}/day capable experimental plant is built and experiments are conducted. In the basic research, it is found that the temperature best for bacilli is 30-45 degrees C. They multiply without difficulty until the target salinity of 3% is achieved and, in a culture test, they can multiply until salinity is as high as 8%. Among submerged membrane filtration methods, hollow fiber membrane microfiltration is the most suitable, with its pressure loss increase rate low and stable at a filtration flux of 0.33m{sup 3}/m{sup 2}/day. Tests are conducted at salinity levels up to 1.5% at the experimental plant, when no adverse effect is detected. A BOD (biological oxygen demand) removal rate of not lower than 99.9% is attained under the condition where BOD=15,000-20,000mg/L. In a study of cost performance in which two methods are applied to a real size plant, it is found that the newly developed method is superior to the conventional activated sludge method because its installation area is approximately 1/3, construction cost approximately 65%, and running cost approximately 60% of what the conventional method demands.

    For the consistent processing of waste automobile in Tochigi Prefecture and the neighboring area, survey/study were made of the thermal recycle using shredder dust, ASR (automobile shredder residue), as fuel as well as the material recycle. As to the amount of material recycle of waste automobile, the amount of potential recycle of iron, copper, plastic, etc. was estimated, and it was found out that the potential recycle of parts such as engine was 40-45%, that of iron scrap 35-40%, and that of ASR 20-25%. The amount of fuel (ASR amount) to be thrown into the gasification power generation system was set up at 150t. As the gasification power generation system, the pyrolysis gasifier and shaft kiln gasification melting furnace were selected. In the study of economical efficiency of the gasification power generation system, the following were considered: ASR processing price, plant cost, subsidy, running cost, char receiving price, power selling price, etc., but even in the case of the pyrolysis gasifier with highest valuation, both payback years and IRR did not reach the target.

    Efforts are made to develop a system to collectively detoxify dioxins and heavy metals in incinerator fly ash or in polluted soil using microbes and/or chemicals. In the use of chemicals, verification tests are conducted for a system to detoxify dioxins and toxic heavy metals simultaneously. In the use of microbes, an effort is made to develop a low cost energy conservation type treatment system based on what is provided by the study of microbes such as Phanerochaete chrysosporium. As for the treatment of fly ash, an effort is made to recycle it into resources usable in the development of marketable products. For the detoxification of dioxins using chemicals, they are dechlorinated in a chemical reduction reaction. For their detoxification with help of microbes, it is found in an experiment of ash fly dioxin decomposition using Phanerochaete chrysosporium that the microbe reduces dioxins in both liquid phase and solid phase systems. The result of verification tests using chemicals shows that the reference level of 3ng-TEQ/g is easily cleared in the treatment of high concentration ash fly. In the detoxification of heavy metals, data is obtained indicating that the elution level of lead in ash fly is found reduced by 70-85% after treatment. (NEDO)

    The R and D were carried out on a system by which the long life of coolant of machine tools can be achieved and a system to process waste efficiently, economically and with less environmental loads, and the FY 2000 results were summed up. In the R and D of a system to prevent degradation of low energy coolant, measurement was made of effects of the degradation prevention system at a laboratory level, and it was found out that propagation of bacteria causing the degradation can be prevented with pH kept high. Further, it was admitted that the alkali effect on metal formability was not very much. As to the coolant processing, in the present situation, most of the coolant is taken back by industrial waste processing dealers. So, the development of the low energy waste liquid processing system is earnestly desired. In the R and D of the low energy waste liquid processing system, test on characteristics evaluation was conducted about each method of systems. Subjects to be improved/solved were extracted such as the point that volatile organic matters are included in condensed water after evaporation of waste liquid and there seems to be a possibility of needing the secondary processing.

    This paper describes the survey and discussion on a system to treat microorganisms generated from organic wastes and recover bio-gas energy as an ancillary facility of buildings. The roof of a building is the most suitable location in terms of open space and odor problem, and because the waste liquid after energy recovery can be flown into the city sewage system. Suitable processes for energy recovery are the primary fermentation, followed further by second stage fermentation purposed of reducing BOD. Since rapid enhancement of the efficiency cannot be expected from the present methane fermentation technologies, it is worth discussing to convert the first step from methane fermentation to hydrogen fermentation, for which technological development is indispensable. Permission by the national or local government would be an important condition. Organic wastes treatment systems with different scales may be considered from wastes treatment in each house to treatment of wastes after collection on the whole city basis. Treating wastes with high water content, such as kitchen refuses and human waste is beneficial among organic wastes being collected and treated by local governments. It is beneficial because sorted collection for that purpose can be carried out, and existing incineration systems can be operated more efficiently. (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.

    Viability was studied of the power generation business using plastic waste as fuel and the methanol production business. In the project, the container packing waste plastic which was sorted/collected is supplied by tender, and the organic waste such as shredder dust is mixed. And the electric power is supplied to the gasification power generation facilities by the pressurized two-stage gasification process, neighboring plants, etc. As an alternative, the methanol production was also studied. As a result of the study, if the total amount of the waste plastic needed at the supply price assumed at present can be supplied, the business can be viable economically even without subsidy, but if the supply risk in supposing tender is considered, a subsidy of approximately 10% of the equipment/plant investment is needed. As to the methanol production as an alternative, it was indicated that the economical efficiency is almost the same, but the profitability gets fast worse due to the waste plastic supply cost since there is not much income and expenses are high despite of the smaller investment size than that in the case of the power generation.
